Summary: Immersion in virtual environments is crucial for scientists to study human behavior. However, creating immersive environments may conflict with the goal of evaluating user response to visual stimuli. This article proposes a device-agnostic approach to color calibration for head-mounted displays, allowing finer control over visual stimuli and context.

Summary: This study aimed to evaluate the tolerance of older nursing home residents to head-mounted display (HMD) virtual reality (VR) by measuring their cybersickness and anxiety state. The results showed that most participants had a good tolerance to HMD VR, with only a few experiencing significant cybersickness symptoms in some sessions.

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: Learning concentration is crucial for learning quality, especially in head-mounted virtual reality interactions. However, current assessment methods are not applicable in these new interactive environments. This study proposes a new assessment method for learning concentration in head-mounted virtual interactions and validates its effectiveness through experiments. Optimizing learning strategies can significantly improve students' learning concentration and assessment scores.

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 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 describes the design of a head-mounted virtual reality system for education on clinical procedures for nursing students and explores the experience of nursing students using the system. The results show that students had a largely positive perception and learning experience. However, there were challenges related to technology and physical discomfort that need to be addressed.

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: Research has found that distances tend to be underestimated in virtual reality (VR), but modern head-mounted displays (HMDs) are better at accurately perceiving distance compared to older ones. This meta-analysis, based on 137 samples from 61 publications, examines egocentric distance perception across 20 HMDs and investigates the relationship between perceived distance and technical HMD characteristics. The results show that judged distance is positively related to HMD field of view and resolution, while negatively related to HMD weight, particularly for heavier HMDs. These findings suggest that improving these technical characteristics may be crucial in addressing the problem of distance underperception in VR.

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 develops three catadioptric optical systems for thin VR HMDs by adjusting the configuration positions of different optical modules. The comparison results show that multiple reflections during the light divergence process effectively reduce the thickness of the optical structure, and reasonable transmission during the reflection process is favorable for size reduction. Based on the designed optical module, a varifocal VR HMD is developed to improve the image quality and sensory experience of users.

Summary: This study evaluated the impact of inter-lens and inter-axial camera separations on depth perception in VR headsets. The results showed that misalignment between the lens and camera separations and the user's inter-pupillary distance can distort depth perception. This phenomenon has been largely ignored in previous studies.

Summary: Cybersickness refers to symptoms like nausea, headache, and dizziness experienced by users during or after virtual reality immersion. Recent studies show that current-generation VR head-mounted displays cause less cybersickness but some symptoms remain severe. The nature of movement and sensory mismatch are key contributors to cybersickness, and biosensors can be utilized for its detection.
