The Effects of Low Latency on Pointing and Steering Tasks

Abstract: Abstract-Latency is detrimental to interactive systems, especially pseudo-physical systems that emulate real-world behaviour. It prevents users from making quick corrections to their movement, and causes their experience to deviate from their expectations. Latency is a result of the processing and transport delays inherent in current computer systems. As such, while a number of studies have hypothesized that any latency will have a degrading effect, few have been able to test this for latencies less than ∼50 m… Show more

“…Research has shown that latency significantly impacts performance in pointing and dragging tasks [14,17,27,31,32] and that it can be perceived from as low as 5-10 ms on a touch device [30]. So far, several methods have been explored to reduce or compensate for end-to-end latency.…”

“…A delay around 70-75 ms has been found already effective in decreasing performance in a VR reaching task [Ware and Balakrishnan 1994], and in tasks which require moving a mouse cursor to a target [MacKenzie and Ware 1993]. In a non-VR and low latency scenario with a Fitts' law style pointing task a latency of about 16 ms already seemed to have an effect [Friston et al 2016]. Samaraweera et al [2013] showed in an experiment using a HMD that inducing a latency of 225 ms can change gait patterns.…”

“…Studies continue to find the effects of latency at lower and lower levels, and these are beginning to reach the limits of the hardware typically used to conduct such tests. For a recent experiment described in [7], we found ourselves in need of a renderer with very low latency. The architecture of traditional GPUs did not allow us to achieve the required latency.…”
