Multi-context photo browsing on mobile devices based on tilt dynamics

This paper presents a photo browsing system on mobile devices to browse and search photos efficiently by tilting action. It employs tilt dynamics and multi-scale photo screen layout for enhancing the browsing and the search capability respectively. The implementation uses continuous inputs from an accelerometer, and a multimodal (visual, audio and vibrotactile) display coupled with the states of this model. The model is based on a simple physical model, with its characteristics shaped to enhance controllability. The multi-scale layout holds both local and global view for users to both control photos and look at the surrounding context in a single framework. We show how dynamics of the physical model can be shaped to make the handling qualities of the mobile device fit the browsing task. We implemented the proposed algorithm on Samsung MITs PDA with tri-axis accelerometer and a vibrotactile motor. The experiment used seven novice users browsing from 100 photos. We compare a tiltbased i...
