The conventional devices such as LASER pointers, remotes, mouse and other devices are meant to offer convenience to users while operating on a projector screen. However, when using multiple devices, transitioning from one device to the other is cumbersome and defeats the purpose of using such devices. The objective is to make operations on a projector screen more interactive. In the developed model, wireless interaction with the screen is accomplished by using Arduino and Joystick Module. The joystick sends the X-Y coordinates to the Arduino, which is then transmitted to the receiver via Bluetooth module, which makes the movement of the cursor possible. The interactive screen is achieved by using an Infrared emitter, an Ultrasonic module and a camera which is positioned behind the projector screen such that it recognizes the movement of the IR rays from the emitter. The image captured by the camera is processed by MATLAB software and mimics the movements on the screen. The ultrasonic module is configured such that it allows the stylus to work only when it comes within a predefined range. These two implementations together make the projector screen interactive and also increases the productivity of the interactive process by eliminating the dependency of the user on multiple devices. |
