Does Multi-modal Feedback Help in Everyday Computing Tasks?

摘要

A study was conducted to investigate the effects of auditory and haptic feedback for a "point and select" computing task at two levels of cognitive workload. Participants were assigned to one of three computer-mouse haptic feedback groups (regular non-haptic mouse, haptic mouse with kinesthetic feedback, and haptic mouse with kinesthetic and force feedback). Each group received two auditory feedback conditions (sound on, sound off) for each of the cognitive workload conditions (single task or dual task). Even though auditory feedback did not significantly improve task performance, all groups rated the sound-on conditions as requiring less work than the sound-off conditions. Similarly, participants believed that kinesthetic feedback improved their detection of errors, even though mouse feedback did not produce significant differences in performance. Implications for adding multi-modal feedback to computer-based tasks are discussed.
