Abstract :
In this paper, we handle an air hockey game which two players play with haptic interface devices as an example of networked real-time games. To keep the interactivity and media output quality high, we enhance the adaptive Δ (delta)-causality control scheme with prediction, which the authors previously proposed. In the enhanced scheme, we change the prediction time dynamically according to the network delay. Also, we subjectively investigate the effect of the enhanced scheme by QoE (Quality of Experience) assessment.
