The proposed extensions to the core system by Spanlang et al. (2014) include, among others, a full-body tracking system, haptics module for sensory stimulation, quantitative measurement tools to record physiological signals, and brain–computer interfaces (e.g., electroencephalography). These extensions generally need dedicated computers to run at high frequency and exchange data with the VR module. However, current off-the-shelf HMD solutions already integrate some of these extra modules. For example, the HTC Vive and HTC Vive Pro (HTC, Taiwan and Valve, USA) allow the tracking of body parts through trackers that can be attached to the users' limbs. Other HMDs, e.g., Oculus Quest (Facebook, USA); HTC Vive Cosmo (HTC, Taiwan and Valve, USA), employ simultaneous localization and mapping (SLAM) to track the user's hands. Several haptic modules are now commercially available, e.g., hand exoskeletons to render haptic interactions with virtual elements (e.g., Dexmo, Dexta Robotics, China; SenseGlove, SenseGlove, Netherlands; VRgluv, VRgluv, USA; HaptX glove, HaptX Inc., USA) or gloves that provide tactile stimulation through vibrations (Senso, Senso Device Inc., USA; Hi5, Noitom International Inc., USA). Although some off-the-shelf VR solutions incorporate eye movement tracking systems, e.g., HTC Vive Pro Eye (HTC, Taiwan and Valve, USA), to date, no HMD devices incorporate physiological measurements and/or brain–computer interfaces.

A VR device (Model: Oculus Quest 2) was used for the experiment (resolution: 1080 × 1200, refresh rate: 90 Hz, field of view:110°). In a laboratory experiment, a car mechanical simulator VR (GameFormatic S.A., Red Dot Games) was considered to provide the working conditions in VR. Additionally, four cameras were placed in four different directions (east, west, north, and south) of the participant to record their postures while performing the manufacturing tasks. The experiment was conducted in a laboratory environment with sufficient lighting and ventilation.
