Summary: CRPS is a rare and severe chronic pain condition with unclear pathophysiology. The study investigated the use of VR in treating unilateral upper limb CRPS. The open-source VR program MV module showed good acceptability and feasibility among participants, with potential for further modification and adaptation for other researchers.

Summary: Recent studies have shown that virtual reality (VR) is an effective tool for changing implicit attitudes towards outgroup members. This study extends this work by investigating the conditions under which VR is effective in changing implicit racial attitudes. The results suggest that when white participants were embodied in a black avatar compared to a white avatar, their implicit pro-white attitudes decreased only when they could see their virtual body both from a first-person perspective and in a mirror.

Summary: In this study, a portable VR-based Mirror Visual Feedback (MVF) system was designed, developed, and tested to monitor behavioral information during a simple motor task. The results showed that the monitored parameters provided relevant information for evaluating the participants' task performance under different experimental conditions.

Summary: This study aimed to test the validity of visual representations of food products in virtual reality by comparing descriptions of actual vs. virtual cookies. The results showed that descriptions of virtual cookies were close to descriptions of the actual cookies. Differences in the weight of brightness and color contrast in the perceptual space of actual and virtual products were observed, which may be due to software-setting configurations that could be optimized for a better match.

Summary: This study investigated the effects of visual environment reproduction methods of virtual reality (VR) on soundscape and landscape assessments, comparing the qualities of urban environments assessment through subjective evaluations. The study found that urban environments were more sensitively assessed through HMD compared to monitors, with negative and positive components more clearly perceived in the HMD environment. Additionally, the surrounded landscape affected urban contextual perceptions positively in HMD and negatively in monitor environments.

Summary: This paper proposes a mixed reality assistive system to aid the navigation of visually impaired people. The system uses a Smart Walker, audio feedback, and vibratory feedback. Through experiments and questionnaires, the feasibility of the system was validated and the impact of different control strategies and paths on the volunteers was compared.

Summary: The experiment found that in a virtual environment, the combination of visual and haptic feedback can enhance presence, with haptic feedback potentially leading to a stronger sense of presence than visual feedback alone. Additionally, haptic feedback is also more effective in helping participants discern the action itself.

Summary: This study compares the skills of experienced laparoscopic surgeons using virtual reality simulators with and without haptic feedback. The results show that using a simulator with haptic feedback leads to higher accuracy, more efficient instrument motion, and avoidance of excessive traction force.

Summary: This study aimed to compare the skills characteristics of expert laparoscopists using VR laparoscopic tasks delivered through haptic and nonhaptic interfaces. The results showed that using a VR simulator with haptic feedback improved accuracy, efficiency of instrument motion, and avoidance of excessive traction force. However, this study did not demonstrate an advantage in skills acquisition with haptic feedback.

Summary: Despite the interest in studying the impact of NPC spectators in games, especially in VR exergames, there is a lack of understanding. This paper presents two user studies that explore the effect of NPC spectators on gameplay. Study 1 found that having NPC spectators and their feedback improved players' performance, experience, and exertion in a gesture-based VR exergame. Further exploration revealed that having a large spectator number and providing feedback can enhance game experience and performance, increase exertion, and reduce negative game experience. These findings provide valuable design recommendations for improving gameplay performance and experience in VR exergames, especially for young adults.

Summary: This study extended the rendering styles of color and size variables in AR geovisualization, and through user experiments, it was found that dynamic variables have higher guidance characteristics than static variables, with shape being one of the most guiding static variables. These results have implications for guiding visual variable selection in symbol design for AR geovisualization.

Summary: Research suggests that precueing information about multiple upcoming steps can improve efficiency in VR and AR task interaction and visualization. In a study on path-following tasks, it was found that participants performed best with precueing two to three upcoming steps with visualizations using lines to show the path to targets, while performance degraded when four precues were used. Conversely, participants achieved best performance with only one precue for visualizations without lines, showing only target positions, and performance degraded with the introduction of a second precue.

Summary: Hyperbaric oxygen therapy (HBOT) is a potential therapeutic modality that has been recognized for its favorable mechanisms in various diseases, including sepsis-associated encephalopathy (SAE). HBOT has neuroprotective effects through its anti-inflammatory and antiapoptotic effects as well as increased tissue oxygenation capacity. However, there are caveats and limitations in applying HBOT in sepsis.
