Evaluation of automobile navigation systems with multisensory information channels

Historically, automobile navigation systems have utilized visual and auditory channels to provide information to drivers. With the recent advancements in tactile technology, the possibility exists to integrate tactile actuators into navigation systems as well. In this research, ninety-six participants used a driving simulator to try out four types of navigation methods: visual, visual + auditory, visual + tactile, and visual + auditory + tactile. The results showed that participants reacted faster when exposed to the navigation guidance modality groups of visual + auditory + tactile and visual + tactile, versus visual only or visual + auditory modalities. In addition, participants experienced greater satisfaction with visual + auditory + tactile and visual + tactile modalities as compared to visual + auditory and visual-only guidance. It is concluded that tactile cues can improve the speed of driver reactions in sudden situations and lead to increased driving satisfaction. Also, combining multiple layers of sensory channels to deliver information does not diminish the prompt responsiveness of the system. It should be noted, however, that tactile cues alone are not sufficient to provide a complete assessment of surrounding road information.
