Abstract

Following a pilot study that suggested that haptic force-feedback could, under certain conditions, lead to 20-50% improvements in time to target in a selection task, a series of experiments further investigated the use of haptic feedback modulated on the basis of cursor position. Improvement in times were obtained for specific haptic assistance techniques, particularly for the more impaired users. Cursor path data was simultaneously collected and found to identify particular features or properties of the motion-impaired cursor movement that can be specifically addressed using modulated haptic force-feedback. This suggests that parameters obtained from temporal and curvature analysis of cursor movements for haptic tasks could be used to set or adapt force-feedback in user interfaces, assisting motion impaired computer users.
