A multi-touch based file navigation interface

File retrieval is a frequently adopted primitive operation for most computer users. As the dominant way for file retrieval, file navigation is yet quite inefficient. Lots Efforts have been made to either enhance the navigation interface or provide alternative. However, they all suffer from the challenge of switching users from their preferred interface to a totally unfamiliar new one. In this paper, we try to avoid such switch by incorporating multi-touch interface into file navigation. We provide a rich set of gestures to support various navigation actions. The natural and comfortable manner of multi-touch can help user to get started much more easily.
