From research prototype to research product

Dashcams support continuous recording of external views that provide evidence in case of unexpected traffic-related acci-dents and incidents. Recently, sharing of dashcam videos has gained significant traction for accident investigation and enter-tainment purposes. Furthermore, there is a growing awareness that dashcam video sharing will greatly extend urban surveil-lance. Our work aims to identify the major motives and con-cerns behind the sharing of dashcam videos for urban surveil-lance. We conducted two survey studies (n=108, n=373) in Ko-rea. Our results show that reciprocal altruism/social justice and monetary reward were the key motives and that participants were strongly motivated by reciprocal altruism and social jus-tice. Our studies have also identified major privacy concerns and found that groups with greater privacy concerns had lower reciprocal altruism and justice motive, but had higher mone-tary motive. Our main findings have significant implications on the design of dashcam video-sharing services.
