Previous research has shown that the use of multimodal signals can lead to faster and more accurate responses compared to purely unimodal displays. However, in most cases response facilitation only occurs when the signals are presented in roughly the same spatial location. This would suggest a severe restriction on interface designers: to use multimodal displays effectively all signals must be presented from the same location on the display. We previously reported evidence that the use of haptic cues may provide a solution to this problem as haptic cues presented to a user?s back can beused to redirectvisualattention to locations on a screen in front of the user [1]. In the present experiment we used a visual change detection task to investigate whether (i) this type of visual-haptic interaction is robust at low cue validity rates and (ii) similar effects occur for auditory cues. Valid haptic cues resulted in significantly faster change detection times even when they accurately indicated the location of the change on only 20% of the trials. Auditory cues had a much smaller effect on detection times at the high validity rate (80%) than haptic cues and did not significantly improve performance at the 20% validity rate. These results suggest that the use haptic attentional cues may be particularly effective in environments in which information cannot be presented in the same spatial location.
