You use computer mouse in your everyday life, whenever you need to activate something. Your Mouse senses motion and clicks and forwards it to computer to get quick and appropriate response. Ordinary mouse works in two dimensional environment and hence detects motion only in X and Y plane. As now professionals are working in the field of 3D graphics motion. Space mouse is a 3D controller device that allows six degree motion i.e. rotation, translation and combination of both. Space mouse has made it possible to manipulate objects in 3D applications. It consists of nine programmable buttons that adjust sensitivity and control motion according to user preferences. It uses calibration free technology for maximum reliability. Space mouse works on the principle of MECHATRONICS ENGINEERING. Mechatronics is the combination of mechanical engineering, electronics engineering and computing. Space mouse technology is well suited for mechanical design, 3D visualization real time video animation and visual simulation.
