We present two interactive approaches for assisting users with visual impairments during photographic documentation of transit accessibility. We are working on an application for camera-enabled mobile devices that drives image composition towards highlighting visual information that is expected to be most relevant. In one interaction modality the user is guided trough small device motions that are expected to center the estimated region of interest in street photographs. In the other modality, the user captures the scene while pictures are processed, and the system alerts when enough data has been collected. The image that best aligns with our attention-getting composition model is then selected for documentation purposes. The specific design of these interactions is evolving to promote small motion behaviors by the user. Future work includes user studies.
