Old pedestrians are overrepresented in fatal accidents. Many studies have consistently shown navigation difficulties that lead to dangerous pedestrian behaviors and/or travel reduction with aging. In this context, the present study aimed at assessing the efficiency of a vibrotactile navigation system to support old pedestrians to navigate in a city.
To this end, 38 participants aged between 61 and 80 and 20 young adults took part in a simulated navigation task where participants had to go from point A to point B in a virtual city. The task was performed with and without a vibrotactile wristband delivering directional messages.
Data showed that both young and old pedestrians benefited from this vibrotactile system. Moreover, stronger effects in the older participants group were observed with more efficient navigation patterns and reduced travel time.
We conclude this system can contribute to maintaining the travel autonomy and reduce the risk of fatal accidents.
