Introduction

After years of development, smart home system has become a very promising field. More and more interesting smart home devices appear in people's lives. Thanks to the accuracy of computers, people are also in the management of smart home systems.

The quality of life has been improved as never before. However, when people enjoy the convenience brought by smart homes, the energy consumption of households has also increased significantly due to the increasing number of electronic devices. This form is detrimental to sustainable development.

Based on the problem of people relying too much on smart devices to cause a lot of energy consumption, the Alpha team worked hard to design an energy visualization system to let people intuitively understand the energy consumption of all appliances in the home. After research, the team concluded that people will pay more attention to interesting things.

This system group trying to complete which can not only show the power consumption of the electrical appliances through different expressions, but also express different information through different colours. In general, the group hopes that through this research, people can understand the energy crisis brought by these sensors and electronic devices while enjoying the convenience brought by smart home.

In addition, in order to facilitate people to manage household electricity, emoji system and one-stop management services, people can monitor and operate all connected home devices on the screen, without having to manually turn on or off the appliances.

Problem Space

Background

Global energy and Carbon Dioxide(CO2) Report (“Electricity,” n.d.)shows that global electricity demand increased by 4% in 2018, nearly twice as fast as the demand of overall energy. Considerable amount of electricity consumption is leading to not only significant decrease of energy reserve, but also sharply growth of gas emission(Gelenbe & Caseau, 2015).

Even though some technologies and well-designed products, like energy-efficient light bulbs, are trying to reduce energy consumption, it is still inevitable that human’s bad behaviour is causing lots of waste. For example, it is not uncommon to see that some people left room without turn off the lights. To target those type of behaviour, Home Energy Manage System(HEMS) was invented to automatically switch off applications that are not being used. However, it is proved that perceived control has more positive effects on users(Dam, Bakker, & Hal, 2010). Inhabitants are more likely to foster habits, for example, by being reminded of turning off not-on-use applications.

Moreover, advanced technology and industrialization largely depend on power generated by types of fuel, which means the technology we rely on to reduce energy use could also be a “energy consumer”, if people don’t have the awareness and habit to be energy-effective in everyday life. A study(Dam, Bakker, & Hal, 2010) has revealed that it is very likely for Home Energy Manage System(HEMS) to become a background after a short-term use.

Energy consumption visualization is expected to be a possible way to save energy by presenting interpreted data to users, allowing them to understand their habits of using energy, encouraging a reflective process , consequently taking actions to reduce energy use, then foster habit. Additionally, once people have such awareness, they would make changes on somewhere else , like office or university, and influence other people around him or her.

Literature Review

In order to enable people to stick to use energy wisely in a long run, a majority of research focused on using technology to raise users’ awareness of energy-effective behaviour by energy consumption visualisation instead of improve performance and functionality of technology inventions for people to rely on. A study (Vassileva, Dahlquist, Wallin, & Campillo, 2013) has revealed that providing users with information and feedback of their energy consumption could increase home inhabitants’ awareness and therefore change their behaviour. What’s more, in some cases, information and feedback can effectively reduce energy consumption between 15% and 25%.

Inan et al.(Vassileva, Dahlquist, Wallin, & Campillo, 2013) studied on devices used for present data and feedback. Four devices were evaluated in their research, including in-home display, TV, SMS, Letters. It shows that in-home display is more effective to raise inhabitants’ awareness, especially when it is installed in the center of the house. Sam et al (Borgeson, Flora, Kwac, Tan, & Rajagopal, 2015) have proposed a platform that integrates a bunch of data analysis algorithms and visualization tools for interpreting energy consumption data. Paul et al (Monigatti, Apperley, & Rogers, 2010) designed a system that can automatically turn on or off applications according to available information, or allows users interactively switch off applications.A web application for users to check their daily, monthly and yearly usage of home power was proposed by Safdar and DoHyeun(Ali & Kim, 2013). Since relevant data would be interpreted and visualised in this application, users would easier to understand, and they argued that web-based application would be convenient for users to check information anytime and anywhere. Xiaodong et al(Fan, Qiu, Liu, Zhu, & Han, 2017) proposed a hand phone application which helps household understand electricity consumption and optimise home energy efficiency.

Apart from devices, forms of visualised information have also been given considerable focus. Michael and Anna(Schwanzer & Fensel, 2010) have researched energy awareness service that could obtain more responses from users. Based on game on Facebook platform, virtually presenting a home, participants could interact with the system, so that their behaviour in the virtual world could reflect what they would do in the real world. Result show that users are responsive to real-time graph and are more likely to optimise their energy consumption in a long-term run. However, research by Kobus et al(Kobus, Mugge, & Schoormans, 2015) shows that only providing real-time feedback is not sufficient for fostering habitants’ behaviour, as it is largely influenced by frequency of use. Therefore, they suggested that systems should be designed for users to easy to access and use.

Existing product

Since Home Energy Management System has been commercially available(Dam, Bakker, & Hal, 2010) in the 1970s, lots of products have been invented to provide information of energy consumption for householders. Instead of solely offering feedback on electricity consumption, products have been optimised to potentially change users’ behaviour. Google, IBM and Microsoft have been put their products into market one after another, but they have to stop their projects as the results haven’t met their expectation.

Smart Plug

Smart plug (Marc, 2018)could be used to control devices, as well as be able to monitor energy use round the home. A smart phone App is often used with it for users to check energy consumption. It cannot be denied that an app-based product would be easier for users to get to know relevant information and able to control household appliances remotely. However, most of time, the data is not able to get access to some family members. For those who don’t have phones used frequently or aren’t good at using Apps, like children and elderly people, Smart Plug are unlikely to make difference on them.

Smart Meter

Smart meter(“Smart Meters Revolutionising Electricity Supply,” 2018) is a electrical device installed at home or places that you want to track and record electricity usage. It could enable inhabitants and electricity providers to read data remotely, and collected data would automatically send to both inhabitants and electricity provider, that allows them to know about their electricity usage in real-time.However, even though inhabitants are able to inform of their electricity usage, most of them don’t have a clear understanding of those numbers. They might only realise that they spend more or less money on this month than last month. Also, messages are usually sent to one person in a family, that means other members know nothing about their consumption. That means it has less influence on changing all family members’ behaviour. Another problem could cause by smart meter is privacy issue.

Home Energy Management System(HEMS)

HEMS(Liz, 2017) usually designed for and implemented at home, consisting of three major parts, including software, hardware and interface. There has been different types of HEMS so far, as what involved in the system could be different. Hardwares often include those smart appliances used for collect usage data, like smart lighting, smart plug. Softwares include platforms for users to check information and manage appliance. Interface products are to display, so that users are able to easily access to information and have a better understanding on that. This system could provide comprehensive and accurate information and could help householders to effectively reduce energy consumption in many different ways. However, it could be, to some extent, energy-consuming and turns to have negative influence on foster people’s energy-saving habit. Also, it could be quite costly for a family to implement such a system at home, which means it is not accessible for some people.

To sum up, electricity used by households share a considerable percentage of global energy consumption, and it has been gradually increasing in these years. Due to the fact that some unnecessary consumption has been caused by people’s behaviour, like leaving room without turning off the light, it is necessary to minimize or even eliminate it. Even though some technologies have been applied to help reduce energy consumption automatically, perceived control would benefit people by raising their awareness and encourage a reflection process. However, what people are shown now is only a series of numbers, saying how much they should pay or how much electricity they have used. People become numb and would not do anything to make the situation differently.

Design Concept

The audience for our design is householders. Our design consists of three main components, a home terminal device, a mobile touch panel, and a smart socket.

First of all, the main function of the smart socket is that when each household appliance is connected to the socket, the socket can intelligently identify the device and collect the power consumption of the appliance and transmit it to the home terminal device.

The function of the device of the home terminal is to connect with the smart socket through the way of the object connection, receive the data from the socket, analyze the data, and then transmit it to the mobile display device.

The mobile display touch device is mainly composed of a touchable display screen, which is divided into upper, middle and lower layers, and is a high-energy-consuming home appliance display area from top to bottom, no operating display area and normal running home appliances. Display area. The above will show all the appliances that are in operation and not in operation. They will appear as icons. There are two options for the icon, one is emoji, the other is the thumbnail of the device represented, and the name of the appliance is displayed below the emoji in the emoji state. Both icons can be switched as you like. This device will receive the processed data from the home terminal device and display it directly. If a device with high energy consumption is detected, the icon will be displayed directly in the high-energy-consumption area, and the icon will be shaken, and if it is emoji in the high-energy-consumption area, it will be an angry emoji icon. To present, if it is a thumbnail of the appliance, it will appear red. Appliance icons that do not have a work area in the middle will appear gray. The icon displayed in the area where the lowest power is normally consumed will show its original color. This device can not only observe the power consumption of home appliances, but also control the switch of home appliances. Simply drag the icon of the high-energy-consumption area or the icon of the running area to the no-operation area in the middle to turn off the appliance. In the same way, the icon of the non-operating area can be dragged to the area where the bottom working normally, and the appliance can be turned on. The division of all electrical appliances is based on the data collected by the terminal equipment. This is based on the data from the network, and an average value is taken to determine.

Related work

Research

Initially, we did a literature review on two aspects, one is about the visualization of energy, and the other is about smart home. Then we analyze and research to determine the target audience of our design as householder, and then we will select two of us after discussion. The problem is combined to design a new design theme for energy visualization of smart homes.

We have found in our literature that the energy crisis is getting worse and worse. At the same time, the consumption of electrical appliances in the home is not well monitored and managed, so it will lead to great energy consumption, and in the context of the rapid development of technology today, Smart homes account for a large proportion, so we hope that our design can combine energy visualization with smart homes, and enhance the festival by visualizing energy consumption while bringing convenience to people's lives through smart homes. The awareness of electric environmental protection reduces the threat that the energy crisis poses to people.

There are many similar devices available, such as Google PowerMeter, Microsoft Hohm, but this type is just a single system, based on network application connection and indoor panel display, this way can only make the connection become single, the interaction is very Less, it is difficult to achieve a long-term use effect, but also difficult to make users develop a good habit of saving electricity.

Based on the analysis of the literature and existing equipment, our team concluded that our design needs to be able to provide timely feedback on the data and give the results of the analysis, and to provide some help to the user, and to make the user easy to understand. Based on the above research, we got our original design and designed a wearable smart glasses.

Original design

The original design was based on AR technology, through the scene recognition function in the glasses, to detect each operating appliance, and to visualize the power consumption through emoji. This original design is a smart wearable eyewear with the main features divided into two parts, at home and outdoors. The function at home needs to be used with a terminal machine that connects all the household appliances and can record and analyze the usage of the power in real time. The main function is concentrated on the smart glasses. This smart glasses can detect every appliance in the home and present the current state of electricity consumption of the appliance through emoji. If it is a high-powered appliance, it will show the expression of angry emoji. By clicking on each emoji expression by virtual click, you can get feedback. Click on the high-energy emoji to give tips for unlocking electricity. With this glasses outdoors, you can see that each store has an emoji, which can create interactive effects through virtual clicks, and each store's expressions can be liked or commented.

Feedback on Pitch

Our design of Pitch Presentations in the Week 6 workshop has received a lot of advice. The first is about the use of emoji. No matter what graphical symbols are used to represent the consumption of power, it needs to be based on the interaction between technology and users to serve the users. In addition, the use of emoji expressions is to do research to see if emoji is acceptable to the public. The other is to make the use of emoji expressions meaningful. You can't just use emoji to use emoji. In addition, the way of using glasses is not very appropriate, because not everyone can accept it. When you are at home, you can observe the use of electricity by wearing glasses. Other interaction methods can be considered.

Summarizing the feedback from the teacher, our team decided to improve our design. The main method we use is an interview. Because for our design we have received initial feedback from teachers and classmates through Pitch Presentations. Determining our initial design ideas is to achieve mobile energy consumption monitoring at home. Using interviews as the main research method can help us to modify the uncertain design points that currently exist. Interviews allow us to understand a wider range of user needs through a broader user community, allowing our designs to obtain more general data information. We did three interviews, and the content of the interview was in appendix.

Interview

For initial design, we notice that there are some aspects we didn’t take into consideration. For example, what kind of information we are going to visualise? is that the cost of electricity or the amount of electricity people used? Those missing information drives us to conduct interviews to find out what could be suitable for users. We interviewed three people, the questions we asked have been attached in appendix 1. By using affinity diagram （shown below in Figure 1), we sorted them into four parts, four places that are helpful for our design and found some important insights from interviews. Result shows that many people haven’t paid much attention to their use of electricity. When they don’t need to pay the electricity bill, they are unlikely to know about how much energy has been used and how much money they have spent. Therefore, it is necessary to design something that could share information about electricity usage among all inhabitants. One interviewee mentioned that she usually doesn’t have special feelings when she is paying the electricity bill, but things go different when compared her cost with friends who spend far less than she does. It shows that comparison or competition might help people to raise their awareness of using electricity wisely and motivate them to save energy. All interviewees thought emoji is a good idea to visualise the data, but one of them suggested that different people could have different preferences, so making it optional could be a possible solution to cater for all users. For example, some people might be more sensitive to their cost, some might prefer carbon footprint, others might be keen on emoji as well.

Plan of Work

Team

Jacqueline is doing her master degree of interaction design at the University of Queensland. This is her last semester. She has completed several design-related courses, including web design, graphic design, physical computing and interaction design, and digital computing, that enable her to horn skills of using design software, like Illustrator, InDesign, and Premiere, Xd. Having a background of mechanical engineering and relevant work experience, she has equipped with hands-on abilities, and that would be helpful to build physical prototype in the team work. In this course, she could help with design and, if needed, physical building. Her aspiration is to enforce her knowledge and skills of design, with which to solve practical issues.

The role of Carmen in this team can be the UX or UI designer, she has the basic knowledge in these two areas and she also has some experience on it through the previous courses, she can do the user research and the evaluation through various methods. she is also good at documenting the process, she can record the meeting content regularly so that we can review and discuss it. For the weakness, she does not have enough knowledge on the technical aspect and she also lack the knowledge on the energy consumption, that will be the barrier in our project. For this course, she expects that she can learn the complete process of design from the research, evaluation and implementation. she also expects that she can learn some technical knowledge from doing the project in this course since I think the technical aspect is also an important part of design so that she can assess the accessibility of a project. she thinks the team member should communicate with each other positively and regularly so that we can figure out the problems and difficulties timely. Besides, we also need to do some work individually to make sure we can finish the project effectively.

Wei Zhou is doing his master degree of information technology at the University of Queensland. He likes every high-technology thing also he likes to create something by his IT skills. He already finishes several computer language courses, now he can handle coding mission in the group. In addition, thanks to his various experiences on using different apps and system, he also has a high standard requirement for UI design or UX design. it could help to give some suggestions during the design part. as an only IT student in group, he probably be asked to in charge most back-end operation and development , which is a big challenge for him, but he is willing to try his best to complete the mission.

Zhengyang Zhang is a graduate student in the Department of Interaction Design at the University of Queensland, this is his third semester. He currently has a lot of skills already in place, such as web design, prototyping, graphic design, digital prototyping, Python, Unity, Adobe series software. He has strong learning and practical skills and can organize group work. He hopes that through his knowledge, he will help the team members to do more design and theoretical research work, and better solve the problems encountered in the course. In general, Team Alpha has the ability to design and produce projects independently. The team mainly consists of designers and programmers. Since the designer is the main part of the team, the team has strong advantages in the UI and UX design of the project. Although IT has fewer team members, the member has extensive programming experience and the ability to handle problems independently. On the whole, Alpha is a group with comprehensive capabilities, members who are organized and willing to face challenges.

Scor(e) Analysis

For this project, there are several criteria can be used to check if the project succeed or not, these criteria. The first one and the most important one is that this project can achieve our purpose that our target users can pay attention on the energy saving, the suitable concept can help us to achieve this criteria and it needs us to do enough research on our target users to learn our target users in depth and we also need to identify the problem space clearly and identify the reason of the problem. The second criteria is the implementation, to achieve this criteria, we need to have the clear plan and the suitable method, we also need to assess the accessibility of our method. The third one is the proper project plan, it can make sure that we can finish the project before the due date.

The strengths within our team is that we have members whose major is interaction design and also member in the computer science, that means our team has the knowledge in the design area and technical area as well. For the design area, we have knowledge in the user research, that will help us a lot to learn our target users in depth so that we can design a suitable concept for our target users. we also have knowledge in the coding part that can help us to design the high-quality prototype to do the test and the knowledge in the prototype, evaluation and test can help us to evaluate our concept and do the iteration to improve our concept. We all are in the semester 3 and 4, we have some experience no matter in the prototype or in the group work in the previous course. Our team are all agree with follow our project plan strictly to make sure we can complete it before the due date and we have enough time to develop it, another strength is that we are all full time students in there and we have enough time and space to have regular meeting, that can help us to discuss the process of the project and the solution to the problem and challenges.

In the domain research part, two members of our group did the research on smart home and two members of our group did the research on the visually energy consumption. These two areas are related to our problem space. For the target users, we are all the international students and there are also many international students around us. For them, they need to rent accommodation in here and they also need to pay the bill by themselves. It is easier for us to contact them and do the user research and evaluation.

There are also some challenges we faced in this project, the limitation of the time and hard to match our timetable. We are in different major and some of us are busy on job finding and some of us have part-time job, we also have different course this semester, so it may hard for us to have a complete period which we can work together, we just have some fragment time period to have discussion and we need to finish the main work individually. Compared with work together, this method may add workload. We will try our best to figure out every difficulty we faced when we do our individual work to make sure the project can be finished as the plan. In addition, we also have some challenges in the concept, we have a short discussion in our team, all of us never pay attention on the energy consumption and we also have limited experience on pay the energy bill. That means we need to do more research on users and trying to understand our users about their feeling and attitude in the energy saving and which aspect they concern most so that we can design a suitable concept for them.

In this project, we have a risk at fail in our goal, we are not sure if the concept can meet users’ need and it hard to measure it since the purpose of our project is draw users attention and makes them to concern the problem of energy waste. We also have not decide which method will be used in this project, so we also have the risk at the wrong approach and it may causes the failure in the project, to avoid the risk, we will give extra time in every stages so that we have enough time to correct them. Another risk is about the workload, most members of our group lack the knowledge in the technical aspect and that means the only member who has the related knowledge need to finish lots of implementation part, it may causes the heavy workload on him, to avoid this risk, we will trying to contribute the work balance, other members will also do some work on the implementation and the design part. We are interested in this project and we all do not want to be the person who causes the failure in the project so we will try our best to complete it, it is hard to avoid all argument during the process but we will communicate with each other timely if we are unsatisfied with anything.

The main stakeholders in our project are users and business company. For these stakeholders, the project may get the negative responses and the positive responses. For the negative responses, users and business company may give up it since it causes them an extra workload, they have to give attention on the monitor but it does not have any effective so they may do not want to continue it. Another possible response is that it is useful for users, they can use the monitor to control the energy consumption in their home and the monitor help them to build the habit which pay attention on reducing the energy waste. For the energy company, under user’s authorized, they can collect the energy consumption data and analysis it, so that they can adjust the energy supplement plan.

Interview1:

Q: Have you ever experienced the payment of electricity? A: Yes Q: Ok, how do you pay for it? A: With Alipay, Q: Ah, then have you paid attention to the electricity usage at home? A: No, Q: OK, then your own or your own electricity habits, you will not pay attention? A: Well, maybe pay attention. Q: OK So do you think that the electricity bill accounts for a large proportion of the daily fixed expenses? A: I think I use a lot of electricity. Q: Ah, living at home is not about commercial use. Well, I think you think that the proportion of electricity bills in daily fixed expenses is relatively large. A: It’s a bit big. Q: So when will the power consumption cause your own attention? Does this pay attention? What is the time or power consumption of which time period will pay attention to you. For example, when is the peak of electricity use, when is electricity, the trough, or the specific time of the day, A: Oh, one night, night, Q: Why is it at night? A: At home. Q: OK at home at night. it is good. So do you think that the use of such electricity bills can be controlled by paying attention to such power-consuming equipment. A: Well, I think so. Q: You think so, then how do you think you can use less of this power-consuming device? Use less power-consuming equipment, then you know how to calculate, he is a power-consuming equipment department. That is, this air conditioner is a power consuming device. A: Oh, you can only say that you are based on the feeling, and then find that he is a power-consuming device, so you think that he is a power-consuming device. Can you judge by how many watts? Then do you think that it is the wattage, it is not the power, it is the power that has been used for a long time, Q: Do you think that you are plugged in, but there is no such appliance, it is also using electricity. A: Well, it should be. Q: Yes, OK, then if you have a visual device with electricity at home, what do you want to show through it? Show what, how much electricity is being used, or what information is displayed, and how much is used. Well, you want him to show it in a different way, it will be more acceptable. How is it going? A: Well, it's not visual, what do you mean? Q: The visualization problem is the screen, which is the classification display, such as air conditioning or in which room something is in use. OK, if we just use emoji, you know an acre. By emoji, it is a reasonable way, and then to show that this power is electricity visualization, can you accept? A: That is to use the emoji to show the power consumption, but I don't think there is a specific data for this. It can only be one that is about the amount of performance. He just said that if you just pass such an expression, It doesn't show much, it only makes you feel that he is using electricity or not using electricity, right? Correct. Q: OK, if he can show it, do you want him to show something more than the amount of electricity used and the amount of electricity used, and what kind of electricity is used? There are still some things, such as or for example, whether the appliance is healthy, A: Oh, if the electrical appliance is healthy, it is really a smart product. Q: Ah, then you are the mobile phone now. It has a system that shows the power consumption of that mobile phone. In the system, it has a power consumption ranking. Have you used it before, right, it will help you pay attention to the power usage of this phone? A: It doesn't really matter to me about the battery usage, but he can only see how much I play with it! Q: Yes, then if you are you, if you lived now, have you ever lived this way? Well, how do you say that you are living in a room with others? The experience, living with others, is not living with relatives, sharing roommates with roommates, the experience of sharing, there is so in the process of your cooperation, will you be willing to share with them The use of your own electricity is what I use is relatively high, what? A: Yes, you can. Q: If you are with a family member, would you be willing? is it acceptable? A: Acceptable, acceptable.

Interview 2:

Q: The first time I saw you lived in the city, right in someone else's house? A: Yes, um. Q: Do you have any electricity bill? A: I have paid it once. Q: How did you pay for it? Is it from the Internet when the computer is online? Is there any relevant information? Is that what you see, or are you seeing the store? When you hand this bill, do you have any awareness of it, just pay it? A: Yes, I just paid him a fee, sent a bill to me, and then only paid. Q: Do you think you will think it is too expensive or how? A: Hey, after I compared it to you today, I found it too expensive. Q: Me too. This is deeply touched. Have you ever paid attention to the use of home electricity? A: No, it works. Well, it will be normal to turn off the lights. Q: Do you think that your habits are good or bad? Or is the habit of others good or not? A: It's me. I won't turn off the computer. I will keep the computer on. It may be bad. Just open the screen, but you will plug it in and check it. But I don't know if he is using electricity. Ok. Then, if you think that if there is a thing that allows you to pay attention to your own electricity consumption, then what do you think he will cause your attention because of what? Q: Really. It is difficult to answer questions. How can you get your attention to the use of electricity? A: When Hu Xing told me that her electricity bill was only 1/2 of mine, it was Kangper's. Ok. Then you have a home, if you can have a charge in your home now, Q: Well, a device that visualizes is to visualize your data. What information do you want him to show you? A: I hope he can convert it directly into money. The tactics are intuitive. I can see directly how much it is. For example, I used a knife and a knife for one day, so I think it will be more than a day, and it will attract more attention. Ok. Q: It is him who wants him to show you every day, or if there is any fun, it is just based on the sky. A: Yes. It is best for him to tell me how much I spend each day and send a txt to me. Q: Do you feel annoying? A: If he sends you every day, I spend six of them today, ah, sixty-six to tomorrow, and I will send it to you every day. Maybe I think it might be very fresh at first. It may be more blind for a long time. If you have a long time, you may not open it. It may be more reasonable once a week. Q: But in a month, it will not be a reminder. A: Because the normal electricity bill is not a quarterly turn? It can be said. For example, when there is a big turning point, such as wow, you suddenly use it high this month, and then give you a reminder, but if everything is normal, it will not give you a better reminder. So what do you use to define this normal abnormality? For example, you often cook at home and then don't let you cook. No. Well, so the re-costing is cheaper because they are home, and they are basic to their home. Should you say it? Uh huh. Q: Then do you think that if you say that you are showing money, um, do you want to show it by just a number, or do you need to show it in other forms? A see how you sent it to me. If you are a person who is similar to a public account, or is it a thing, may he be better with graphics or table comparison? But if it's just a txt, I think the numbers are obvious, because I can compare the difference between the two txt? Q: Then would you like to interact with him? A, for example, I can set a value, for example, more than ten to twenty to thirty knives a week, then you can give me a reminder, a reminder, etc. Q: Because we are thinking about it now, a genius of Edel has come up with a Kang site that has a molding machine to show your electricity consumption. what do you think about this? A: I think Ai Luo is a genius. You are indeed a genius, well, and now quietly say his bad words. I think, look at it, it depends on what kind of information you want. Some people may look at the numbers more sensitive, and then some people may feel that today is tomorrow, it seems to be annoying, if every day is A smiley face may be more comfortable. It is best to choose. There are a lot of different things, for example, you can use a tacit or a number to make you use it. Ok. Q: Then you will feel that if you are living in the second slogan, then if the electricity consumption is seen by your roommate, would you feel acceptable? A: TV power is not for everyone. I don't have this point, I think. not worse. Ok, Q: Just for example, he is because of air conditioning, or the use of such electrical equipment, and then placed in a public area, then you will accept? Because the information may have this thing in your house, there is no such thing in his house. Then this may be your own use. Then this entire display will be in an experimental space, and you will accept it. Information Bell. A, I think it’s OK, because it’s going to cut into the electricity bill. The two people’s time at home is different. Then there isn’t a point that is absolutely fair, so everyone decided to go to the sun. The money should be No such contradiction, Q: If you say the other one next to you, is the power of your entire house and the one next to him and Hu Xinjia? A: It is not who is sharing your electricity usage information. I will be very unhappy, especially with breathing. But you may be fine. That is, if it is, for example, we are using the same power company, then I can share it with you. This is how most of the average is, it may be better, but if it is for a single user, I may feel strange, just a little peeping at the privacy of others. Q: Oh, yes, what you mean is to give you an average. For example, the one in the area is still between your friends. It can be a regional or power company. More average. A: Like my friends, I often don't eat at home. Then the information you think is a friend or your same power company will give you some excitement, that is, let you save electricity, or um. Q: Which way will promote you to say that you want to enable TV in the same community, or to compare with friends? Because if it's just an average, then if you are below the average, you will feel it doesn't matter. I think this is what you think will give you a kind of mentality that I use a little more. A: I think you should divide this into categories. For example, the electricity used in my air conditioner is a part. Then when this part is compared with the average, I may be higher. I will have a restraining effect in my heart. But if you say, for example, um, if you have friends who don’t cook at all, then in this case, if you compare with others, I can only think that it may be because I cook, so I use Most of them, he does not have a way to save electricity, but if you separate these into parts and then transfer a part to compare with me, I may be able to save electricity, for example, use less. What about a little air conditioner? Q: Is there any change in your attention to electricity in China and Australia? Who will consider the electricity bill in China? A is because it is cheap to live with my parents, because it is not a problem with my parents. You have paid in one month. Didn't you have a monthly electricity bill of more than RMB? No, I don't remember me. I don't know how much electricity is paid at home. Right, it is because it is very cheap, so it will not consider this kind of problem, and some prepaid things in the domestic city, it is not late checkout, so you have no way to go. That card may be over, and N can't be used for a long time. Q: Can't you say that you think that electricity bills account for a large proportion of daily fixed expenses? A: I don't think so. In fact, okay, I think it is a normal cost, but if you want to compare with the water fee here, it may indeed be a benchmark, because most of the water fee is not money. Q: Do you think that the use of electricity bills can be controlled by paying attention to power-consuming equipment? Is the first store equipment turned off? Q: If you give you some information about the power-consuming equipment, then do you think that your understanding of this does not mean this? A: You have not asked this question. He just said that he has already said the electricity bill. Q: The power consumption display of the mobile phone will help you pay attention to the use of electricity. A: It will help me to pay attention to me from time to time. I should look for a charging cable from time to time. Q: If the power consumption of each appliance is recorded, do you think it will change your electricity usage habits or achieve the effect of saving electricity? A: At least you should give me at least one because I should be like it. There is a standard. It is similar to what we just said should have an average or how, otherwise I have no way to compare with myself. I don’t. Know which one is really used and which one is really used less.

Interview 3:

Q: Have you ever experienced the payment of electricity? A: Yes. Q: Ah, what is the way to pay? A: Alipay payment Q: OK, have you paid attention to the electricity usage at home, or your own electricity habits? A: Very few, but I usually pay attention to some situations that say electricity. Q: OK, do you think that electricity bills account for a certain proportion of the daily fixed expenses? A: Well, this should be? Q: It should be OK. Then, when do you think that the power consumption will cause your own attention, is there any attention to which time period from the middle of the day? A: Well, this may be related to the season. If it's hot or cold, there will be something like electricity or air conditioning that consumes a lot of electricity. I will pay more attention when I'm driving. Q: Ah, do you think that the use of electricity bills can be controlled by paying attention to such power-consuming equipment? A: It should be controllable, but you have to see how it is implemented. Q: What is the specific? A: Ah, then you have a device that can be used to visualize electricity at home. If you have this kind of electricity in your home, this kind of electricity visualization device, Q: What do you want him to show? A: Well, maybe I think it might be a daily statistic. Q: That is to say, how much electricity will be used in a day, right, then, then, what might be compared, right, then he might compare it with other electrical appliances, and then you can see what is being compared with electricity. High, right. Q: OK So what do you want it to be? What is the display method? A: Ah, that’s the show. You say, for example, what you said about the power consumption or the amount of electricity. Well, I think it might be interesting to have a picture on the map. It is like an icon. It means that some power consumption is more interesting. Q: So if you use emoji to use emoji as an expression, then it might be a reasonable and acceptable way to visualize the power, can you accept this kind of recruitment? A: But you estimate how you can grade him. Well, I think it is more difficult to do analysis with a certain department. At that time, it may be more difficult for me to compare. I don't know which smile and face will be. To what extent, how does one go about how he passes, and then let you reach out to let you see where he is using electricity or what? It is best for him to have other logos. Yes, it can at least tell me which one is harder to compare and which one is simpler. Q: So what is the current level of power consumption on the mobile phone? A: It is how much electricity is used every day, or which ones are high-power applications. Does this cause you to pay attention to the use of electricity? Well, I generally don’t care, I only pay attention to the current power of the mobile phone. Then, based on the current power, as well as my daily experience, I can still use the remaining time. Q: OK, then there is still ah, we may be living in this kind of share house here, then you want your own power share? It’s just that you and your roommate are your own power consumption. Ah, the person in the whole apartment is the one who lives in the room. You said that you are talking about information, right, you use electricity information, right. A: Ah, I don’t feel very happy, I’m not happy, yes, because I’m a more exaggerated person, so I’m probably because I’m compared to other people’s feelings. Happy, Q: Ah, would you be willing to play this kind of electricity consumption with family members, for example with parents or later, with children and girlfriends? A: Well, my family is fine, because I feel that because I live together after all, everyone has to participate in the use of electricity, so it does not matter, right. Q: So, when you live in the country, for example, living with your parents, you are living in Australia with this roommate. Do you have any concern about the power consumption of this power consumption? A: Yes, ah, because at home, basically parents are paying attention to electricity. Well, they will be more careful than me. I’m so at home, I don’t pay much attention to electricity here, because I have to Spend money, so I still have to pay attention to it. Q: Then if the power consumption of each appliance is recorded, do you think this way will change your electricity habits or save electricity? A: Well, if I can always pay attention to it, I may think it will be more interesting, that is, it will save my electricity. Yes, you think it is a meaningful thing. Q: OK, there is such a way that you feel that this is an environmentally friendly and low-carbon way. A: Well, to a certain extent.
