PICTORIAL VIEW OF INTERACTIVE SYSTEM:

AIR HOCKEY

The principles of air hockey are very similar to regular ice hockey. In ice hockey the puck is made to slide smoothly across the playfield using a layer of ice whereas in air hockey a cushion of air essentially levitates the puck millimeters above the playfield reducing friction. This makes the game extremely fast-paced and enjoyable. The lift generated to levitate the puck is achieved by creating tiny holes all over the playfield in a grid that blows air at high pressure from underneath. The air is then forced through these holes and exits with a high velocity countering the weight of the puck making it float on a layer of thin air.

ROBOTIC ARM

A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. The links of the manipulator can be considered to form a kinematic chain. The terminus of the kinematic chain of the manipulator is called the end effector and it is analogous to the human hand. However, the term "robotic hand" as a synonym of the robotic arm is often proscribed.

CONTROLLING COMPUTER WITH GESTURES

Recently Gesture controlled Laptops or computers are getting very famous. This technique is called Leap motion which enables us to control certain functions on our computer/Laptop by simply waving our hand in front of it. Two ultrasonic sensors are placed on top of the monitor that will read the distance between the monitor and the hand using Arduino, based on this value of distance, certain actions are performed on the computer. To perform actions on the computer Python pyautogui library is used. The commands from Arduino are sent to the computer through a serial port (USB). This data will be then read by python which is running on the computer and based on the read data an action will be performed.

INTERACTIVE LIGHT

This system is gestured controlled ,the sensors detect a movement that corresponds with a command and it responds with the appropriate output. It's an Arduino and PIR motion sensor based automatic light control system. Table lamp on, off and color changes are the main functions. The Arduino board will take input from the sensor and changes the color. Nowadays it is becoming famous due to its unique working principle, hence eases human work and makes life easy.
