Vibrotactile biofeedback has proven to be effective in clinical studies, however effectiveness in a setting dealing with activities of daily living has not been studied. For vibrotactile biofeedback to function in these settings, real time and fast interaction are required. The fast interaction is largely depended on the reaction time to a stimulus and is therefore researched in the current study. To test the reaction time, a prototype measurement setup has been developed, consisting of vibrotactile actuators, visual stimulators, an inertial measuring unit, touch sensitive fields, a microcontroller board and custom developed scripts for data processing. Simple reaction tests were performed with five conditions: light stimulation only, vibrotactile stimulation on the trunk, vibrotactile stimulation on the arm and multimodal stimulation on the trunk with light stimulation and arm with light stimulation. The goal of the study was to determine the difference in reaction time between the conditions. The second goal was to determine the difference in movement paths between the conditions. Reaction time on light sensation was found to be faster than both vibrotactile conditions. However, the multimodal condition of light stimulation and vibrotactile trunk stimulation resulted in faster reaction times. The results suggest a contribution of vibrotactile stimulation on reaction time in the multimodal situation. Even tough the movement paths and movement workspaces were not in the same plane between the conditions there were no differences in movement paths found that could explain the differences in reaction times.
