Mobile devices with touchscreens are often used pinch and flick gestures to navigate large information spaces such as maps, text documents, images, and web pages. As an alternative to such gestures is peephole displays where the content shown on the mobile screen is updated according to the device movements across the underlying workspace. Another promising interaction on mobile devices is to make the device spatially-aware of finger gestures in the air around the device.

In this project, we investigate how these three tchniques (i.e., pinch and flick, peephole and in-air finger detection) can be used for navigating and browsing content in a continuous workspace, such as a map.
