This paper assesses QoE (Quality of Experience) of output quality and interactivity in a networked air hockey game with haptic media. For consistency and causality, we employ the adaptive Δ-causality control scheme with adaptive dead-reckoning. We clarify the influence of network delay on QoE.
In this paper, we investigate the influences of the difference in network latency among haptic media, sound and video on the quality of experience (QoE) for a haptic media, sound and video transfer system. In the case where network delay jitter exists, we subjectively assess the operability of haptic interface device, sound output quality, video output quality, inter-stream synchronization quality,...
In this paper, we deal with a remote haptic calligraphy system in which a teacher instructs multiple students at remote location show to write characters while conveying the sense of force by multicast communications. We also propose an error control scheme which transmits important media units (MUs) multiple times which include the positional information in the case where the speed of the teacher's...
This paper deals with a haptic media and video transfer system in which users can touch and move a real object located at a remote place by using haptic interface devices while watching video of the object. Making use of the system, the users can do collaborative work in which the users lift and move the object by holding it between the styluses of the haptic interface devices. In the system, we investigate...
