Abstract [en]

This thesis is focused on realizing the multipoint touch screen in an easier and cheaper way. All of the experiments are based on the theory of total internal reflection. A prototype model was built by using Wii remote(Wiimote), Bluetooth, infrared (IR) led and glass. With the IR-led being placed on the sides of glass plate, the lights from diodes propagate inside the glass and will not leave it with an intervention. If a finger is pressed on the glass plate, the light rays reflected on the top surface of the plate underneath the finger get “frustrated” and some portion of it no longer stays in the glass. This means that some light leaves the plate directly under the point where a finger is pressed, optimally in a 90° angle to the glass plate. We can now capture all pressure points (IR light spots) digitally. Using the Wiimote, which has the infrared (IR) camera on the top and embedded Bluetooth chip, the pressured points positions are captured and sent back to laptop via the Bluetooth. The thesis is focused on the experiments to realize the Wiimote touch screen which is built on the prototype model. Several trials with two different types of IR-led have been used here. With the result shown in the final experiment, the normal glass and fiber glass can be used as touch screen successfully
