In 360-degree video streaming, Most solutions are based on tile-based streaming that divides videos into tiles and streams the high-quality tiles corresponding to the user's viewport areas. However, these methods cannot transmit different combinations ...

In this paper, we propose a taxonomy for 360° videos that categorizes videos based on moving objects and camera motion. We gathered and produced 28 videos based on the taxonomy, and recorded viewport traces from 60 participants watching the videos. In ...

With the rapid growth of mobile web search, it is necessary and important to understand user's examination behavior on mobile devices in the absence of clicks. Previous studies used viewport metrics to estimate user's attention. However, there still ...

The computing power and bandwidth of the current VR are limited when compared to the high-quality VR. To overcome these limits, this study proposes a new viewport dependent streaming method that transmits 360-degree videos using the high efficiency ...

In recent years, geographic information has entered the mainstream, deeply altering the pre-existing patterns of its production, distribution, and consumption. Through web mapping, millions of online users utilise spatial data in interactive digital ...

An algorithm is presented which clips on a non-rotated viewport positioned anywhere on the viewport plane relative to the viewing vector. This is a generalization of the traditional three-dimensional clipping algorithm in which the viewing vector ...
