“…They found time delay to prolong task completion time by a multiplicative factor. Similar effects have also been observed in delayed haptic environments (Alhalabi, Horiguchi, & Kunifuji, 2003;Wang, Tuer, Rossi, Ni, & Shu, 2003). Recently, Jay et al (2007) examined the impact of delayed haptic and visual feedback from the partner in a collaborative virtual environment with two operators.…”

Time delay is recognized as an important issue in haptic telepresence systems as it is inherent to long-distance data transmission. What factors influence haptic delay perception in a time-delayed environment are, however, largely unknown. In this article, we examine the impact of manual movement frequency and amplitude in a sinusoidal exploratory movement as well as the stiffness of the haptic environment on the detection threshold for delay in haptic feedback. The results suggest that the detection of delay in force feedback depends on the movement frequency and amplitude, while variation of the absolute feedback force level does not influence the detection threshold. A model based on the exploration movement is proposed and guidelines for system design with respect to the time delay in haptic feedback are provided.

“…Finally, the perceived mass and damping coefficients caused by network delay are derived from the transparency criterion between Z app h and Z e , as follows: 4 Non-zero phase lag in a sample and hold may generate energy, and thus the sample and hold operation becomes a fundamental instability factor, even in a local haptic simulation [13].…”

“…Haptic-based interaction provides participants with tactile sensation as feedback media, and it is known to enhance the effectiveness of most NVE (networked virtual environment) applications dramatically. Therefore, haptic-based interaction can be very useful in the areas of remote surgery, remote manipulation, sports training, multi-player online games, and many others [2][3][4].…”

Priority-based haptic event filtering for transmission and error control in networked virtual environments

A data filtering scheme is proposed for transmission and error control of haptic events in hapticbased network virtual environments; this scheme is called as priority-based haptic event filtering. Because a high update rate of approximately 1 kHz is required for haptic rendering, sophisticated transmission rate control and reduction schemes are necessary for the haptic events. Although existing schemes can reduce the transmission rate without any perception impairment, they are very sensitive to packet losses. In this paper, we prioritize the haptic events according to the delay and loss effects. Utilizing the proposed haptic event prioritization, the proposed filtering scheme adapts the transmission rate and updates the predicted loss rate according to the current network state. Our simulation and experiment results confirm that the proposed scheme can effectively select important haptic events and guarantee an improved haptic interaction quality over a bandwidth-limited lossy network than existing transmission schemes tailored for networked haptics.
