Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Video-based latency measurement of the 3B system found approximately 73 ms average end-to-end latency (SD 45), below the 150 ms real-time threshold, with an average frame rate of 75 fps. → Lugrin J-L 2016

q2 · i? · design · r3
Pre-user study technical measurement using a video-based frame-counting method with videos recorded at 480 Hz. The measurement found latency "approximately 73 ms (±SD 45)" and the system "delivered an average frame rate of 75 frames per second" for about 400 K triangles per frame.
"The average end-to-end latency between movements of the participant's head and corresponding updates of the projected images was evaluated to approximately 73 ms (±SD 45), which is below the threshold required for real-time interactions [≤150 ms (Lugrin et al., 2012)]."
