TLDR
In this article, the effect of latency on the user ability to perform a task after 185.5 ms was found to be significantly higher on the force perception rather than on the displacement perception.Abstract:
Latency is detrimental to haptic systems, specifically in networked telepresence systems. Although the latency effect on stiffness is well studied in the literature, it is not very clear if the latency effects on the stiffness perception are due to the displacement perception or the force perception. In this study, we propose passive probing which involves force perception alone, without any displacement of the finger, for studying latency effects. A psychophysical experiment is conducted with a set of artificially induced latencies which provides a quantitative measure of the effect of these latencies on three parameters: Just Noticeable Difference (JND), the time taken to reach the reference forces and the maximum overshoot. The results showed that the latency has a significant effect on the user ability in task performance after 185.5 ms. From the observation, the latency effect on JND in passive probing is similar to that of the stiffness perception (active probing) task which shows that the effect is significantly higher on the force perception rather than on the displacement perception.read more

HapticProxy: Providing Positional Vibrotactile Feedback on a Physical Proxy for Virtual-Real Interaction in Augmented Reality
TL;DR: Zhang et al. as discussed by the authors simulate positional vibrotactile feedback (PVF) with multiple vibration motors when colliding with virtual objects in AR, which could significantly reduce the alignment offset between virtual and physical objects with tolerable task completion time increments.

TL;DR: The observed trends suggest that video content is unlikely to disastrously overflow the Internet, at least not anytime soon, by analyzing commercial residential traffic in Japan where the fiber access rate is much higher than other countries.

Perception of Delayed Stiffness
TL;DR: The results of the experiment indicate a systematic dependence of the estimated sti fer upon the delay between position and force, and findings are consistent with sti fness estimates based on dividing the maximum force by the perceived amount of penetration.

TL;DR: The results indicate that the temporal accuracy of visual-haptic interfaces has to meet stringent requirements in order to optimize the overall realism that users experience.
