Microsoft: Integrated Videos and Maps for Driving Directions

October 26, 2009

From Microsoft Research:

(a) Original spacing of panoramas. (b) Final spacing of video frames, after slowing down at landmarks/turns and speeding up between. (c) Straight ahead orientation. (d) Final orientation with look ahead. (e) Widening the view and freezing the landmark thumbnail. One frame of the route video. The field of view is automatically expanded to the left to emphasize the building landmark at this turn. The visual proxy is highlighted. Integrated video and mapping application. Abstract

While onboard navigation systems are gaining in importance, maps are still the medium of choice for laying out a route to a destination and for way finding. However, even with a map, one is almost always more comfortable navigating a route the second time due to the visual memory of the route. To make the first time navigating a route feel more familiar, we present a system that integrates a map with a video automatically constructed from panoramic imagery captured at close intervals along the route. The routing information is used to create a variable speed video depicting the route. During playback of the video, the frame and field of view are dynamically modulated to highlight salient features along the route and connect them back to the map. A user interface is demonstrated to allow exploration of the combined map, video, and textual driving directions. We discuss the construction of the hybrid map and video interface. Finally, we report the results of a study that provides evidence of the effectiveness of such a system for route following.
