Currently, optical sensors are not the mainstream use in mice and trackballs. With consumers demanding enhanced capabilities as well as smaller technology for their computer peripherals, using lasers or LEDs in smaller mice and trackballs is one of the most effective ways of achieving that result. Laser technology makes it possible to track on various surfaces, so you’re not limited to your desktop, as well as providing a higher degree of precision in tracking.
This presentation provides information on challenges and resolutions with mouse/trackball design, from concept to creation. Avago will review the different optical navigation techniques, how the tracking actually works and what can be done to improve upon it. Answers to key challenges in designing very thin mice (less than 5mm) as well as optical sensor capabilities in trackball technology and design will be provided as well as recommendations.
At the end of this presentation, you will know how the laser technology works in tracking, how it can work in a small mouse and other design considerations, and future trackball technology.
