Abstract

In a test drive experiment of the short-distance mobility device (electric wheelchair standard) WHILL, young test participants drove the vehicle both with and without side mirrors, and the evaluation data after the test drive under each condition was compared and analyzed. The results revealed that the presence of side mirrors makes driving more comfortable significantly in situations where checking behind is required. Many test participants checked behind them both with the side mirrors and with their eyes when parking. Test participants who drive cars on a daily basis tended to check the side mirrors frequently when driving forward, and used them effectively. Many test participants rated the side mirrors as expensive, but also expressed a desire to purchase them, and rated the mirror surface measuring 4.5 cm high x 11.5 cm wide was narrow in height.
