Figure Lengend Snippet: Schematic of the experimental set-up showing the silhouette of an actual participant (a). The backpack computer allows tether-free movement in the space between the motion trackers. The backpack computer is controlled with Laptop I; Laptop II is used to record an overhead view of the experiment. A coordinate frame attached to the HMD denotes how head roll, pitch and yaw were measured. A snapshot of the virtual environment with virtual characters looking up along with an overhead view in the inset is also shown (b). (Online version in colour.)

Article Snippet: Experimental set-up The experimental set-up consisted of a head-mounted display (HMD) (HTC Vive, with 1080 × 1200 pixel displays sampled at 90 Hz, HTC Corporation, New Taipei City, Taiwan) integrated with motion trackers (Lighthouse laser emitters, HTC Corporation), to present a walkable virtual environment, a backpack computer (MSI VR one backpack PC, 2.90 GHz processor, 16 GB memory, 3.3 kg, MSI Corporation, New Taipei City, Taiwan) for running a tether-free simulation of the virtual environment on the HMD, a pair of noise-cancelling headphones (Bose QuietComfort Acoustic noise cancelling headphones, Bose, Inc., USA), a laptop (Laptop I, Dell Latitude E5570, Dell, Inc., Round Rock, TX, USA) to initiate the environment simulation and record the participant's perspective of the virtual environment using a remote desktop connection and another laptop (Laptop II, Dell Vostro 1520, Dell, Inc.) to record an overhead real-world view of the participant movements with a web camera (Logitech C920 Pro Webcam, Newark, CA, USA) in the real world ( ). fig ft0 fig mode=article f1 fig/graphic|fig/alternatives/graphic mode="anchored" m1 Open in a separate window Figure 1. caption a7 Schematic of the experimental set-up showing the silhouette of an actual participant ( a ).
