PocketDRAGON: a direct manipulation video navigation interface for mobile devices

We present PocketDRAGON, a demonstrator prototype that allows direct manipulation video navigation on mobile touchscreen devices. In contrast to traditional video navigation techniques, PocketDRAGON does not require any overlay UI elements that occupy valuable screen real estate and obstruct the users’ view on the video. Also, direct manipulation video navigation techniques have been shown to compare favorably to the established timeline slider interfaces in terms of performance times, intuitiveness, precision, and perceived ease of use. Our demonstrator system still uses a backend server for the computationally expensive parts of the algorithms but delivers the full-fledged user experience on the mobile device.
