Abstract

The emergence of personal mobile computing and ubiq- uitous wireless networks enables powerful field applica- tions of video streaming, such as vision-enabled command centers for hazardous materials response. However, ex- perience has repeatedly demonstrated both the fragility of the wireless networks and the insatiable demand for higher resolution and more video streams. In the wild, even the best streaming video mechanisms result in low-resolution, low-frame-rate video, in part because the motion of first- person mobilevideo (e.g., via a head-mountedcamera)dec- imates temporal (inter-frame) compression. We introduce a visualization technique for displaying low-bit-rate first- person video that maintains the benefits of high resolution, while minimizingthe problemstypicallyassociatedwith low frame rates. This technique has the unexpected benefit of eliminating the "Blaire Witch Project" effect - the nausea- inducingjumpiness typical of first-person video. We explore the features and benefits of the technique through both a field study involving hazardous waste disposal and a lab study of side-by-side comparisons with alternate methods. The technique was praised as a possible command center tool, and some of the participants in the lab study preferred our low-bitrate encoding technique to the full-frame, high resolution video that was used as a control.
