This poster presents a study on the role of vision for driving safety. Based on a naturalistic driving study on visually impaired drivers, the presenter argues that good visual acuity is not crucial for driving safety. A hazard perception experiment suggested that motion perception plays an important role in driving safety. Inspired by the findings, a collision detection system based on image motion is developed. While the resolution of the camera was equivalent to 20/60 visual acuity in human, road tests demonstrated that the approach can be more effective than the methods based on object recognition. Two messages from this poster: (1) many people with low vision probably should have the privilege of driving like normally sighted people; (2) the limitation of object recognition methods for unknown obstacles in automated driving can be addressed through motion analysis.
