Grid-based interaction for effective image browsing on mobile devices
René Rosenbaum, Heidrun Schumann · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2005
Compared with stationary environments, mobile devices suffer from a number of limitations like small screen space, limited processing power and bandwidth. Thus, it is very difficult and expensive to browse large images by using current mobile hardware. In this publication a new image browsing technique especially designed for mobile devices with limited screen space is introduced, and a completely new concept to communicate important image properties based on a well-defined grid structure is proposed. As every browsing technique needs reasonable concepts for user interaction, this publication introduces intuitive ways for image exploration, which need only little action of the user during browsing and processing power to calculate an appropriate image representation. To decrease the need for expensive bandwidth in remote environments, it will also be shown how to combine this browsing technique with image compression and transmission. Thus,a whole system for image communication is presented. Due to its excellent compression performance and flexibility, the modern JPEG2000 image coding standard is adopted as a foundation of the proposed system regarding a compliant compression and efficient transmission of the image. Concrete performance measures show the applicability of the introduced system.
