An Approach to a Laser-Touchscreen System

  As modern day technologies advance, so have different methods in which users can interact with computers. Computers are currently being used in combination with devices like projectors for teaching and presentations, in which the mouse and the USB wireless presenter are two of the main presentation devices. However, such devices like the USB wireless presenter, is limited and cannot fully encapsulate what it aspires to simulate, a computer mouse. This device fails to simulate the movement of a mouse but may only simulate the actions of a right and left arrow key. This paper proposes a novel approach to allowing users to interact with a computer from a distance without the need of a mouse, but instead using a laser pointing device, a projector and a web camera, by developing a novel laser-touchscreen system. The test results confirmed the laser pointer could be used to simulate the movement of the mouse as well as mouse clicks with very high accuracy. It could also be potentially used in a gaming environment, especially in first person shooter games.
