designing a new computer mouse and evaluating some of its functional parameters

background: this study aimed to design a new mouse and evaluate some of its functional parameters. the prototype of an ergonomic mouse was made according to design principles. methods: the study was conducted from 2011 to 2013 in the department of ergonomics in shiraz university of medical science. functional parameters including movement time (mt) and error rate of the new mouse were evaluated by 10 participants based on iso 9241-9 standard. results: the application of design principles in the new mouse resulted in improving mt and error rate so that they could be comparable to those of a standard mouse. mt, in both the standard and the new mouse was 0.846 and 0.864 s, respectively. error rate of the standard and the new mouse was reported as 13% and 19%, respectively. statistical analysis showed no significant difference between the two mice from these perspectives. conclusions: apparently, the studied functional parameters of the new mouse were similar to those of the standard one. the new mouse could be an appropriate substitution for the standard mouse without losing its positive characteristics.
