This study addresses the pressing issue of prison rehabilitation by comparing traditional and Virtual Reality (VR) based training services offered by the General Directorate of Prisons in Saudi Arabia. Utilising Technology Acceptance Model (TAM) metrics such as perceived usefulness, ease of use, and enjoyment, the study evaluates the acceptance of VR technologies across two different headset platforms. Findings reveal that VRbased training services received significantly higher acceptance ratings than traditional methods. Both VR platforms were highly rated in terms of perceived usefulness, ease of use, and enjoyment but showed no significant differences between the headsets. These results indicate that VR-based methods could be more effective, engaging, and safer alternatives in correctional rehabilitation programs. Importantly, this research contributes to the field of Human-Computer Interaction (HCI) by suggesting design frameworks tailored for effective interventions in training and rehabilitative contexts where safety and psychological health are of high concern.

“…We define three applications matching XRindoor and outdoor applications, and a motion controller, as summarized in Table . 1. Indoor encompasses something such as a living room or meeting room designed for VR usage, with a field of illumination (FOI) covering the typical 140 degrees field of human-viewing [3] and a measurement range at least 5 m to sufficiently cover the room size. High-resolution information is needed to give good user precision, although the wide FOI makes it difficult to retain sufficient detail at longer distances.…”

For the advancement of XR headset device technology, the projection screen and display technologies are a major focus of discussion. The ToF sensor system used for detecting human viewing area at a given power/space budget is also considered an inevitable feature. We report on the constructed systems and the achieved performances with newly developed refractive-diffractive hybrid lenses, a diffuser (Platanus ® ) and a dot projector (Ardisia ® ). These lenses were designed using simulator-based ray tracing and a Maxwell equation analysis, and subsequently fabricated using SCIVAX' nanoimprinting technology. These lenses were customized with VCSELs to cover the wide range of field of illumination (FOI) from 30 to 150 degrees. Platanus ® presented considerably uniform and controllable illumination with high phase uniformity over shorter distances, thus we believe it meets the high-resolution sensing requirements for XR.Ardisia ® gave high intensity dots without showing the zeroth order light and any collimation lenses. And its intensity could be even higher with an increased number of VCSEL emitters, without changing the dot count as would be the case for an ordinary DOE, so that long-range illumination is easily achievable. Ardisia® with a FOI of 60x45 degrees enabled illumination over 10 m with an optical power of only 2 W, suggesting that the efficiency and compactness of Ardisia® is suitable for 3D sensing optics for XR applications. And the same can be adopted in automotive applications such as for driver monitoring system (DMS) and potentially LiDAR. In this paper, several experimental results for ToF system are presented.

The objective of the AccesSim project is to design a wheelchair simulator using Virtual Reality and a robotic platform to detect and illustrate accessibility issues in complex environments. In order to be efficient, the robotic platform must provide haptic and vestibular feedbacks to different profile of end users: urbanists to wheelchair users. It must be modular and adaptable to each one of them. In this paper we focus our robotic platform capable of adapting its configuration and feedback rendering based on the user. The design of the platform is described. The capacity of the platform to reproduce the motion of a wheelchair in a specific study case is tested experimentally. Finally the results introduce the possibility of adapting the dynamic feedback rendering based on a specific user and environmental situations.
