User Requirements Survey for Interactive Video Tour Product Development

As we all know, panoramas provide essentially static view, instead of truly interactive experiences. While the interactive video tours can help provide a compelling sense of presence. When experiencing a video tour, users can move at will, look at any directions and change the point of view anytime.

You can film a tour of an environment that you wish to display and then use image-based rendering techniques to replay the tour interactively. So users can truly move along a set of predefined tracks, choose between different directions of motion at intersection, and look in any direction. Besides, the interactive tour will have a high resolution and dynamic range. The system easily incorporates multimedia objects such as navigation maps, pop-up stills, audio enhancements, and video textures.
