A HAPTIC SHAPE-CHANGING BLIND SPOT AWARENESS SYSTEM FOR ELDERLY DRIVERS
A common result of aging is a reduced physical, visual and cognitive ability. This study evaluates the efficacy of a shape-changing steering wheel and seat belt for blind spot awareness during lane changing. Lane changing is a difficult maneuver for elderly drivers requiring a high cognitive load. To this end, two haptic, shape-changing warning types were assessed through an experiment with participants aged from 65 to 92 years. As for preference measures, the participants’ perception of effectiveness and efficiency, in stimulating the sense of safety, of the haptic feedback and their overall satisfaction were used.
Experimental results showed that the highest preference scores were achieved by the steering wheel, which showed a statistically significant difference. Participants did not notice the haptic, shape-changing feedback of the seat belt. In addition, the experiment suggested factors that need to be studied to further improve the performance and preference of haptic blind spot awareness, such as translation of velocity, and shape-changing intensity and size.
