"Liking" other Drivers' Behavior while Driving

Driving is a social activity: Drivers need to coordinate with each other to share the road infrastructure. The social relationship between drivers also influences the driving behavior. With everywhere available connectivity and the broad penetration of social network services, the relationship between drivers on the road may gain more transparency, enabling social information to pass through the steel shell of the cars and giving opportunities to reduce anonymity and strengthen empathy. In this paper, we introduce a concept that enables drivers to express their appreciation for other drivers' polite driving behavior through gestural interaction, in order to improve their driving behavior by social awareness.
