Effects of precision demand and mental pressure in aiming and tracking tasks
conference paper
From August 24-29, 2003 in Seoul, Korea the XVth Triennial Congress of the International Ergonomics Association and the 7th Joint Conference of Ergonomics Society of Korea / Japan Ergonomics Society were held. The central theme was "Ergonomics in the digital age". The objective of the present paper was to gain insight into the effects of precision demands and mental pressure on the applied grip and click forces on the computer mouse. Two computer mouse tasks were used: an aiming and a tracking task. Performance measures indicated that the levels of the independent variables resulted in distinguishable levels of accuracy and tempo. Precision demands had no effect on the applied grip and click forces on the computer mouse, but large effects on performance. Mental pressure had an almost significant effect on the applied grip force during tracking and substantial effects on the applied grip and click forces during aiming, with grip and click forces increasing by 51% and 40% respectively. Mental pressure had small effects on accuracy but large effects on tempo during aiming.
