Article No.: 56
DOI: 10.1145/3132041

Cloud gaming has been recognized as a promising shift in the online game industry, with the aim of implementing the “on demand” service concept that has achieved market success in other areas of digital entertainment such as movies...

Game Input with Delay—Moving Target Selection with a Game Controller Thumbstick
Mark Claypool
Article No.: 57
DOI: 10.1145/3187288

Hosting interactive video-based services, such as computer games, in the Cloud poses particular challenges given user sensitivity to delay. A better understanding of the impact of delay on player-game interactions can help design cloud systems and...

Novel Hybrid-Cast Approach to Reduce Bandwidth and Latency for Cloud-Based Virtual Space
Xueshi Hou, Yao Lu, Sujit Dey
Article No.: 58
DOI: 10.1145/3205864

In this article, we explore the possibility of enabling cloud-based virtual space applications for better computational scalability and easy access from any end device, including future lightweight wireless head-mounted displays. In particular, we...

Cloud Baking: Collaborative Scene Illumination for Dynamic Web3D Scenes
Chang Liu, Wei Tsang Ooi, Jinyuan Jia, Lei Zhao
Article No.: 59
DOI: 10.1145/3206431

We propose Cloud Baking, a collaborative rendering architecture for dynamic Web3D scenes. In our architecture, the cloud renderer renders the scene with the global illumination (GI) information in a GI map; the web-based client renderer renders...

ASAP: Adaptive Stall-Aware Pacing for Improved DASH Video Experience in Cellular Networks
Ahmed H. Zahran, Jason J. Quinlan, K. K. Ramakrishnan, Cormac J. Sreenan
Article No.: 61
DOI: 10.1145/3219750

The dramatic growth of video traffic represents a practical challenge for cellular network operators in providing a consistent streaming Quality of Experience (QoE) to their users. Satisfying this objective has so-far proved elusive, due to the...

On the Effectiveness of Offset Projections for 360-Degree Video Streaming
Chao Zhou, Zhenhua Li, Joe Osgood, Yao Liu
Article No.: 62
DOI: 10.1145/3209660

A new generation of video streaming technology, 360-degree video, promises greater immersiveness than standard video streams. This level of immersiveness is similar to that produced by virtual reality devices—users can control the field of...
