Summary: This article proposes a novel design of a VR head-mounted display that provides near-correct focus cues over a wide depth of field. By using a combination of backlight, liquid crystal display panel, and focus-tunable lenses, the system can generate the correct focal blocks based on the depth information of the 3D imagery, reducing visual discomfort for the observer.

Summary: This work presents a perspective-corrected video see-through mixed-reality head-mounted display that combines edge-preserving occlusion and low-latency capabilities. The system performs tasks such as image reconstruction, occlusion masking, and scene reprojection to ensure consistent spatial and temporal composition of real and virtual objects. It uses a hybrid algorithm to refine edges and fill disocclusions, achieving acceptable latency and spatial accuracy. The work is expected to enhance the realism of mixed reality systems.

Summary: This study introduces a perspective-corrected video see-through mixed-reality head-mounted display that can preserve occlusion and has low-latency capabilities. Key tasks include reconstructing captured images to match the user's view, occluding virtual objects with real objects to provide correct depth cues, and reprojecting the scenes to match the user's head motions. The system utilizes algorithms that focus on edge smoothness and disocclusion to generate depth maps quickly, and uses a two-phase temporal warping architecture for registration and user motion tracking. The implemented prototype achieved acceptable latency and spatial accuracy in testing. This work is expected to enhance the realism of mixed reality systems.

Summary: The occlusion-capable optical see-through head-mounted display (OC-OSTHMD) has been actively developed in recent years to accurately present mutual occlusion between virtual objects and the physical world in augmented reality (AR). In this paper, a novel approach for achieving mutual occlusion for common OSTHMDs is proposed by designing a wearable device with per-pixel occlusion capability. Upgraded OSTHMD devices are demonstrated with a prototype using HoloLens 1, showcasing real-time virtual displays with mutual occlusion. A color correction algorithm is also introduced to mitigate color aberration caused by the occlusion device. Potential applications, such as texture replacement of real objects and realistic semi-transparent object display, are demonstrated, aiming to achieve universal implementation of mutual occlusion in AR.

Summary: The study found that using a stereoscopic widescreen display may be more effective for restoring motor function in upper and lower limbs compared to a head-mounted display. On the other hand, a head-mounted display might be more appropriate for applications that require precise exocentric distance judgment.

Summary: The use of head-mounted displays (HMDs) and hand-held displays (HHDs) may impair individuals' ability to control stability during locomotion, especially when perturbations are present. Additional cognitive resources required for dual-tasking with these displays result in delayed response execution and diminished effectiveness of stability control mechanisms.

Summary: In this paper, a novel approach for realizing mutual occlusion for common OSTHMDs is proposed. The OSTHMD devices are upgraded to be occlusion-capable by attaching the device before optical combiners. A wearable device with per-pixel occlusion capability is designed, and a color correction algorithm is proposed to mitigate the color aberration caused by the occlusion device. The proposed system demonstrates the potential applications of texture replacement and realistic semi-transparent object display.

Summary: This study investigates the impact of the field of view (FOV) size of optical see-through head-mounted displays (OST-HMD) on a user's ability to memorize spatial locations and transfer that memory to the real world. The results show that smaller FOV size does not significantly affect user performance in both short-term and transfer tests, but users with a larger FOV rotate their heads less. Additionally, the proximity of objects to memorize interacts with smaller FOV sizes.

Summary: This study investigated the effects of using head-mounted displays (HMDs) for a virtual field trip to Greenland. The results showed that compared to a video, using HMDs had a positive immediate effect on students' self-efficacy and interest, and a lasting effect on self-efficacy, outcome expectations, and interest approximately two and a half weeks after the intervention.

Summary: This paper presents a head-mounted virtual reality study comparing gaze, head, and controller pointing for selection of dynamically revealed targets. The results show that gaze and controller pointing are faster than head pointing, and increased screen width improves performance up to a certain point. The study also validates the applicability of existing pointing models and uncovers differences for gaze at known and unknown target positions.

Summary: This paper introduces a system for emotion recognition in virtual reality environments, based on multimodal bio-signals acquisition using wearable devices. The system records EEG, EDA, PPG, and SKT signals, and includes a human-computer interaction interface for researchers to carry out emotion recognition research using VR as stimulus presentation. The performance of the system is validated through experiments, showing comparable signal quality to dedicated bio-signal measuring devices and efficient recording of alpha rhythm.

Summary: This study evaluated balance recovery methods and intervention timing during the use of VR, finding that video-see-through triggered 500 ms before the onset of fall can effectively help users recover from falls. However, triggering video-see-through at fall onset has a significant negative impact on balance recovery.

Summary: This article presents a systematic review of the usage of optical see-through head mounted display (OST-HMD) in augmented reality (AR) surgery applications from 2013 to 2020. The study revealed that the Microsoft HoloLens is increasingly dominating the field, with orthopaedic surgery as the most popular application. Surgical guidance is the most common context, and segmented preoperative models are the dominant visualization method. Human factors play a significant role in the utility of OST-HMD.

Summary: Mobile displays, particularly head-mounted displays, have a significant impact on operator mobility, performance, and situation awareness in safety-critical systems, as demonstrated in a real-time physical simulation of maritime navigation. The use of HMDs can improve operator performance, situation awareness, and mobility by reducing information retrieval effort and allowing operators to maintain situation awareness without returning to fixed displays. This highlights the importance of operator mobility in safety-critical systems for improved performance and situation awareness.
