A field study was conducted to evaluate the use of an additional tactile signal in a navigation system and to examine the effect of hearing loss on eye movements. 32 participants took part in the study, whereof 16 with normal hearing and 16 with moderate hearing loss.

The participants performed two preprogrammed navigation tasks. In one they received only visual information from the navigation system and in the other there was an additional vibration in the seat to guide the driver in the right direction. The order of which the systems were tested was balanced over the participants.

SMI glasses were used for eye tracking, and the field of view was recorded with a marker showing where the driver is looking. Predefined targets were analyzed, e.g. the mirrors, the speedometer and the navigation display. A questionnaire including questions about the experience of the two navigation systems was given to the drivers afterwards.

Results revealed that hearing loss is associated with lower speed, higher satisfaction with the additional tactile signal and more glances in the rear view mirror. Additionally, tactile support lead to less gaze data on the navigation display, regardless of hearing status.
