A neural-network-based context-aware handoff algorithm for multimedia computing
Tsungnan Lin, Chiapin Wang, Po-Chiang Lin
Article No.: 17
DOI: 10.1145/1386109.1386110

The access of multimedia computing in wireless networks is concerned with the performance of handoff because of the irretrievable property of real-time data delivery. To lessen throughput degradation incurred by unnecessary handoffs or handoff...

Towards attention-centered interfaces: An aesthetic evaluation of perspective with eye tracking
Ingmar S. Franke, Sebastian Pannasch, Jens R. Helmert, Robert Rieger, Rainer Groh, Boris M. Velichkovsky
Article No.: 18
DOI: 10.1145/1386109.1386111

The established method of representing three-dimensional space on a two-dimensional surface involves camera based, point of regard systems, comparable in design to the early “camera obscura”. However, geometrical limitations of such...

Exploring large-scale peer-to-peer live streaming topologies
Chuan Wu, Baochun Li, Shuqiao Zhao
Article No.: 19
DOI: 10.1145/1386109.1386112

Real-world live peer-to-peer (P2P) streaming applications have been successfully deployed in the Internet, delivering live multimedia content to millions of users at any given time. With relative simplicity in design with respect to peer selection...

Low-latency adaptive streaming over tcp
Ashvin Goel, Charles Krasic, Jonathan Walpole
Article No.: 20
DOI: 10.1145/1386109.1386113

Media streaming over TCP has become increasingly popular because TCP's congestion control provides remarkable stability to the Internet. Streaming over TCP requires adapting to bandwidth availability, but unforunately, TCP can introduce...

Data placement and prefetching with accurate bit rate control for interactive media server
Seung-Ho Lim, Yo-Won Jeong, Kyu Ho Park
Article No.: 21
DOI: 10.1145/1386109.1386114

An interactive Media Server should support unrestricted control to viewers with their service level agreements. It is important to manage video data effectively to facilitate efficient retrieval. In this paper, we propose an efficient placement...

Video game design using an eye-movement-dependent model of visual attention
Li Jie, James J. Clark
Article No.: 22
DOI: 10.1145/1386109.1386115

Eye movements can be used to infer the allocation of covert attention. In this article, we propose to model the allocation of attention in a task-dependent manner based on different eye movement conditions, specifically fixation and pursuit. We...

Predictive real-time perceptual compression based on eye-gaze-position analysis
Oleg V. Komogortsev, Javed I. Khan
Article No.: 23
DOI: 10.1145/1386109.1386116

This article designs a real-time perceptual compression system (RTPCS) based on eye-gaze-position analysis. Our results indicate that the eye-gaze-position containment metric provides more efficient and effective evaluation of an RTPCS than the...
