Study, Development, and Design of a Mouse

A series of research studies were conducted to develop design criteria for a general purpose mechanical input device. The design criteria and parameters were established with ergonomic studies which included task analysis, competitive analysis and human performance testing. By taking a leadership role in the production issues, Human Factors engineers were successful in having the results of their research implemented into a new design. This report is a case study which offers some insight into methodological and design issues associated with producing an ergonomically designed product.
