PhotoPrompter: a framework of photography encouragement in a strolling trip using ambiguous information.

ABSTRACTThis paper introduces a smartphone-based system that encourages photography by enhancing a user's awareness of the surrounding environment during a stroll in a city. When a user approaches a pre-registered location for photography, the system notifies the user by vibrating the smartphone. The system only displays the distance to the location and a photograph of the location on the smartphone screen; it does not provide detailed information, such as that given by a map. A user study performed during a stroll in a city confirmed the application of this system. The results demonstrate that ambiguous information provided by the system increased the opportunity for photography and fortuitous discovery.
