[POSTER] Photo Billboarding: A Simple Method to Provide Clues that Relate Camera Views and a 2D Map for Mobile Pedestrian Navigation

This paper describes a mobile pedestrian navigation system that provides users with clues that help understanding spatial relationship between mobile camera views and a 2D map. The proposed method draws on the map upright billboards that correspond to the basal planes of past and current viewing frustums of the camera. The user can take photographs of arbitrary landmarks on the way to build billboards with photographs corresponding to them on the map. Subjective evaluation by eight participants showed that the proposed method offers improved experiences over navigation using a standard 2D map.
