ABSTRACT

The main objective of this study was to measure and model how the human hand interacts with examples of contemporary mouse designs and how this physical interaction may be associated with subjective aspects of comfort. The physical interaction between the mouse and the hand was captured for twenty-four healthy individuals using an electromechanical coordinate measurement machine, generating three-dimensional landmarks and surface features for the hand, mouse, and work surface. Four mouse designs, representing progression along the pronation-supination continuum were assessed. Results for three-dimensional handmouse measures of the metacarpophalangeal arch, dorsum of the hand, and vertical displacement of surface landmarks of digits I, IV, and V are reviewed and related to measures of perceived comfort. Negative perceptions of comfort were associated with an increase in the displacement of the hand from the work surfaces for landmarks associated with digits I, IV, and V.
