Findings from multiple studies demonstrated large effects of using computer mouse and also some other types of pointing devices on developing Cumulative Trauma Disorders (CTD). The main cause of these injuries considered being user s non-ergonomic posture. In fact, using most pointing devices involves pressure on nerves at entrapment points, increased neural tension and use of muscles while contracted. Accordingly, wide range of pointing devices are developed regarding to ergonomic design issues and to modify user s body posture but the classic mouse still remains the most popular device. This paper tried to evaluate available pointing devices in the market regarding to users favorites and ergonomic design factors through an analytical process which promote creativity, and then explore the limitations and possibilities for developing new design solutions. This hypothesis also examined that the most of computer users resist any big modification in their posture; therefore they tend to use pointing devices which are more consistent with their previous daily experiences and looks more natural from their perspective.
