ABSTRACT

In this paper, we design and implement a transport scheme for haptic interactions in CVEs (collaborative virtual environments). When interacting with haptic interfaces in the CVEs, network delay jitter and packet loss over the Internet may seriously degrade the user experience of haptic interactions. The existing transport schemes tailored for networked haptics claim that their schemes could improve the quality of networked haptic interaction. However, what seems to be lacking is that they do not focus on reducing the transmission rate and end-to-end delay of the haptic events. On the contrary, the proposed transport scheme reduces the transmission rate of haptic events by using network-adaptive aggregated packetization and the priority-based filtering. It also compensates the network delay jitter and loss in order to improve the haptic interaction quality by using haptic event error control and priority-based buffering scheme with low processing delay. According to the experimental results, the proposed transport scheme provides shorter playout delay and less transmission rate than those of the existing networked haptic transports.
