The effects of 0.2 hz varying latency with 20-100 ms varying amplitude on simulator sickness in a helmet mounted display

TLDR: It is indicated that a varying latency is associated with greater experience of SS among HMD users than constant latency, and that added constant latency on its own does not appear to be associated with the experience of higher levels of SS in an HMD.

Figure 3.6. Vergamatic II. The physical set up, not including the Vergamatic II, consisted of a steel frame, front surface mirror, felt square, and head stabilizer with chin and forehead rests. See Figure 3.6 for setup. At the top of the steel frame were two planks of wood with a horizontal space between them. The Vergamatic II was located on top of these planks with the LED arrays projecting downward through the space between the planks. The light from the LED arrays projected downward reflecting on a front surface mirror which reflected the light toward the eyes of the participant. A front surface mirror was used so the participant did not see a double image as would occur with a regular household mirror. The head stabilizer was aligned so the light from the vertical green LED array was reflected to the left eye of the participant. The head stabilizer was in place to prevent excessive head movements that may interfere with accurate measurements. A square felt
