I Can See on My Feet While Walking: Sensitivity to Translation Gains with Visible Feet

A survey of real locomotion techniques for immersive virtual reality applications on head-mounted displays

“…The lower walking speed in the HMD condition relative to the real world walking is consistent with earlier studies [35] which show that participants wearing an HMD tend to walk slower compared to realworld walking, which is likely explained by the encumbrance of the HMD machinery.…”

“…Steinicke et al [35] have quantified, through a psychophysical experiment with a two-alternative forced-choice task, Detection Thresholds (DTs) for how much humans can be redirected. In an experiment to determine the ability to discriminate whether a physical rotation was smaller or greater than the simulated virtual rotation they found that rotational gains (gR) between 0.67 and 1.24 cannot be reliably estimated by humans.…”

Examining Design Choices of Questionnaires in VR User Studies

“…Similarly, Shute discussed how to embed questionnaires into games without disturbing the game flow [169]. These considerations With Q, not reported: [2, 15, 16, 20, 27, 30, 31, 33, 34, 38, 42, 43, 50-52, 54, 63, 67-70, 73-76, 86, 89, 90, 92, 93, 95, 101, 105-107, 109-111, 115, 117, 120,122,124-126,130-132,134,135,139-143,145,151,156,164,167,173, 174, 178-181, 184-186, 188, 190, 192, 193, 195, 199, 200, 204] OUTVRQS: [3,8,29,77,84,94,98,114,121,138,157,162,176,177,187,191,196,197] INVRQS: [6,28,37,44,55,66,85,100,108,127,148,[158][159][160]198] Without Q: [9,11,19,22,40,59,71,91,133,153,182,194,<...>…”

Investigating Effects and User Preferences of Extra- and Intradiegetic Virtual Reality Questionnaires

“…Most of them use extradiegetic UIs. Their design choices differ from each other in (1) the means of presentation, for example using floating headup-displays [9,12,23], world-referenced UIs [14,18,24,29,[34][35][36] or UIs attached to the body [43], (2) the means of interaction, mainly by using VR-controllers [18,23,24,29,35], gamepads [2,9,14], answering orally [12] or using free-hand interaction via Leap Motion gesture-based inputs [32,34,36,43], and (3) other design choices like presenting single or multi-questions at once, answering via Likert-scales [29,[34][35][36]], text-based buttons [23] or sliders [2,9,14,18].…”
