Towards the Impact of Gamers' Adaptation to Delay Variation on Gaming Quality of Experience

摘要

Both online and cloud gaming services require a very low network delay to create a good Quality of Experience (QoE) for their users. The required network latency cannot be guaranteed due to the current best effort-nature of the network, and as a result, network latency often degrades the gamers performance and QoE. In this paper, the adaptability of gamers to different variations on delay is investigated both subjectively and objectively using three self-developed games. The results show that gamers can adapt to constant delay while they are playing and change their behavior if the actions in a game are predictable. Such adaptation leads to a significant increase in gamers performance and QoE. The paper also provides evidence that regardless of performance frequent delay switching annoys gamers. The result of this study can be used to create a network resource allocation technique which controls a congested network by giving more priority and resource to the unadaptable games than the adaptable games.
