INDENTIFYING CLIENT'S OBJECTIVE

##3.1-QUESTION AND ANSWERS

1)What exactly is the WELCOME BOT?

In places such as colleges, offices, hospitals, hotels, and public buildings, visitors often need immediate assistance to know where to go, whom to contact, or what information is available. Depending entirely on reception staff can cause delays, especially when many visitors arrive at the same time.

The Welcome Bot aims to provide an automated, interactive, and user-friendly welcoming system that can detect visitors, greet them, communicate through voice, display important information, and provide guidance or access to information through QR codes.

3)How is WELCOME BOT useful to society?

🤝 Makes people feel included — It gives newcomers a friendly greeting instead of making them feel like outsiders.

🧑‍🤝‍🧑 Helps people connect — It can direct new members to relevant groups, discussions, or support communities.

🛡️ Improves online safety — It can explain community rules and help prevent spam, scams, harassment, and inappropriate behavior.

♿ Improves accessibility — It can automatically provide instructions and resources in a simple, consistent way.

⏰ Saves volunteers' time — Instead of people repeatedly explaining the same information, the bot can handle basic questions automatically.

🌐 Helps large communities — Schools, nonprofits, public-service groups, and community organizations can use it to welcome many people at once.

💬 Supports different languages — A bot can provide welcome information in multiple languages, helping more people participate.
