User interface for video observation over the internet

摘要

This paper presents the design and application of a system for live video transmission and remote camera control over the World Wide Web. Extensive testing of the Internet Video Server(IVS)promoted us to improve its user interface. The Global View extension of IVS Was developed which enables the generation of panoramic images of the environment And a more intuitive control of the camera. The live video frame is superimposed on A 360°static panoramic picture. By interactively moving a rectangular frame in the Panoramic picture, the user locally selects the new direction of the camera.
