“…In this interface, it takes 33-41ms from the time the user's finger moves to the time the virtual finger moves. However, according to previous research, there is a point of reduced operability ranging 24.3-44.3ms [43]. As it takes less than 10 ms to read the finger position in the environment of this interface, the time required for processing within unity is assumed to be significant.…”

“…How low the latency needs to be depends on the application. Kadowaki et al [66] studied the users' performance solving a simple pointing task with their hand being projected at diferent motion-to-photon latencies. The authors concluded that if the latency is greater than 24.3 ms, the user's performance starts to decrease.…”

The next generation of wireless networks fosters the adoption of latency-critical applications such as XR, connected industry, or autonomous driving. This survey gathers implementation aspects of different image and video coding schemes and discusses their tradeoffs. Standardized video coding technologies such as HEVC or VVC provide a high compression ratio, but their enormous complexity sets the scene for alternative approaches like still image, mezzanine, or texture compression in scenarios with tight resource or latency constraints. Regardless of the coding scheme, we found inter-device memory transfers and the lack of sub-frame coding as limitations of current full-system and software-programmable implementations.

“…However, unconscious effects appear to occur at lower levels. On 2D tasks, Kadowaki et al found that there was no difference in performance in a direct touch task at 4.3 and 24.4ms [32]. Friston et al found that performance was perhaps worse, or at least not better, at very low latencies, possibly explained by behaviour of the human motor system having inherent latency [17].…”

Figure 1: Latency was tested both through a hardware instrumentation-based measurement (bottom left) and the new cognitive latency technique (bottom right) on four different devices. The first device, Prism, was an ad-hoc system that attached a pair of colour cameras to an Acer Windows Mixed Reality device (1 top left). This system aimed at providing a top end video see-through quality. We also tested Oculus Quest (2), Oculus Rift S (3) and the Valve Index (4). On the Bottom Left, hardware instrumentation-based measurement setup. Cameras (A and B) are synchronized to capture at the exact same time by the board (2). While (1) is a clock running at sub-millisecond accuracy. The clock for camera (B) is seen by the HMD (3), which displays the video see-through. The scene was kept well illuminated to reduce automatic exposure time problems of the HMD cameras. On the Bottom Right, a participant performing the rapid decision making task while wearing a see-through VR headset.
