Tile-Based Panoramic View in Mobile Devices

Abstract:

Cylindrical panoramic view is a 360-degrees horizontal representation of a certain scene. The user can navigate interactively through the scene and change their view angles. Basically, panoramic views are often high-resolution, high-definition and consume a significant amount of bandwidth for transmission through Internet in mobile platform. In this paper, a method is proposed by combining a proposed tile-based algorithm with scrollViewDidScroll protocol of the iOS platform. With the tile-based algorithm, the panoramic views are divided into tiles and only tiles of interest are viewed on the mobile screen. Besides, the scrollViewDidScroll protocol of the iOS platform is used to link back the end of panoramic view with the start of the panoramic view to produce a cylindrical panoramic view. From here, the user can view the same output as panoramic views on a mobile device but using limited bandwidth, memory, and number of processors. Based on the evaluation, the respondents gave favorable response to the method.
