Vibrotactile Targeting in Multimodal Systems: Accuracy and Interaction

Tactile displays that enhance appreciation of virtual and real environments are becoming increasingly common. Extending a series of prior studies, we explored spatial resolution for individual vibrating sites on very dense arrays worn on the observer’s trunk, and their interaction with simultaneously-presented visual stimuli in an isomorphic display. Stimuli were composed of individual stationary vibrating sites in a tactile array worn on the chest or flashes of light projected on a screen. In all cases, the task for the observer was to identify the location of the target stimulus, whose modality was defined for that session. In the multimodal experiment, observers were also required to identify the quality of a stimulus presented in the other modality. Performance was affected by the location of the target tactor within the array and the presence and location of the distractor stimulus.
