On the Perceptual Artifacts Introduced by Packet Losses on the Forward Channel of Haptic Telemanipulation Sessions
In this work we study the position and velocity signal reconstructions using predictive coding when packets are lost during telemanipulation sessions and classify the high-level haptic artifacts perceived by the users. The usage of packet-switched networks for bilateral telemanipulation systems is challenging due to several adversities such as low transmission rates, packet delays, jitter and losses. The previously proposed deadband-based haptic data reduction approaches selectively decrease the high transmission rate of the force-feedback and position/velocity samples on account of human perception limitations. Recently, an error-resilient perceptual haptic data reduction approach was proposed to address the packet losses in the feedback channel. However, the impact of faltered transmission on the forward channel and its subjective influence on the user are still an open issue and thus are treated in this paper.
