Virtual reality games on accommodation and convergence

Mohamed Elias Z, Batumalai UM, Azmi ANH

Appl Ergon, 2019 Nov;81:102879.
PMID: 31422241 DOI: 10.1016/j.apergo.2019.102879

Increasing popularity of virtual reality (VR) gaming is causing increased concern, as prolonged use induces visual adaptation effects which disturbs normal vision. Effects of VR gaming on accommodation and convergence of young adults by measuring accommodative response and phoria before and after experiencing virtual reality were measured. An increase in accommodative response and a decrease in convergence was observed after immersion in VR games. It was found that visual symptoms were apparent among the subjects post VR exposure.

The mediating effect of Internet gaming disorder's symptoms on loneliness and aggression among undergraduate students and working adults in Malaysia

Insufficient attention has been given to the integration of the mediating effect of Internet gaming disorder (IGD) symptoms on loneliness and four components of aggression-physical aggression, verbal aggression, anger, and hostility-in the Malaysian context. In the present study, 410 participants with (a) at least 1 year of Internet gaming experience and (b) between ages 20- to 39 years were recruited using the probability proportional to size sampling method. Participants were undergraduate students and working adults. Self-reported questionnaires (the Internet Gaming Disorder Scale, University of California, Los Angeles Loneliness Scale, and the Buss-Perry Aggression Questionnaire) were used. The present study found that loneliness positively predicted four components of aggression (i.e., anger, hostility, physical aggression, and verbal aggression) and symptoms of IGD. Relationships between loneliness and the four components of aggression were partially mediated by IGD symptoms. The present study enriches and consolidates existing empirical evidence, particularly in the Malaysian context. If the mediating effect is not emphasized, it may lead to spurious conclusions that can significantly diminish the effectiveness of interventions that are meant to manage aggression.

Exergaming for Individuals with Spinal Cord Injury: A Pilot Study

Mat Rosly M, Halaki M, Mat Rosly H, Cuesta V, Hasnan N, Davis GM, et al.

Games Health J, 2017 Oct;6(5):279-289.
PMID: 28968153 DOI: 10.1089/g4h.2017.0028

OBJECTIVE: Commercially available exergames that are for wheelchair-bound individuals with spinal cord injury (SCI) are scarce. This study sought to identify exergames for individuals with SCI that are "dose-potent" for health benefits.
MATERIALS AND METHODS: Six participants with SCI were recruited for a pilot study to investigate the exercise intensity of selected exergames (Move Tennis, Move Boxing, and Move Gladiator Duel) for the potential to improve health. Issues relating to exergaming for individuals with SCI were identified, and a Move Kayaking exergame was conceived using relevant design processes in an iterative manner. These processes included the following: participant needs and requirements, system requirements (hardware), system architecture (physical and operational views), and integration and verification of the finished system. Emphasis was given to operational and physical designs of the Move Kayaking exergame.
RESULTS: Move Boxing, Move Gladiator Duel, and Move Kayaking achieved moderate intensity exercise, while Move Tennis only achieved exercise of low intensity based on participants' metabolic equivalent. However, all four exergames achieved at least moderate intensity based on individuals' ratings of perceived exertion (RPE).
CONCLUSION: The intensity classification while playing Move Boxing, Move Tennis, Move Gladiator Duel, and Move Kayaking, using RPE, reported adequate exercise intensities prescribed by exercise guidelines.

Sleep deprivation and emotional problems such as stress, anxiety, and depression commonly occur in university students. Exercise is beneficial to ameliorate those problems; however, university students are not serious to take up physical activity. Commercially available exergame such as Xbox® 360 Kinect is one of the alternatives. This study aims at investigating the feasibility and the potential efficacy of using Xbox 360 Kinect game among health care undergraduate students. A pilot two-armed parallel randomized controlled trial was implemented. A total of 36 undergraduate students was recruited and randomly allocated into the intervention group (playing Xbox 360 Kinect) or the control group (continue with normal daily routine). The intervention group received 30 minutes of Xbox Kinect activity, three times per week for 6 weeks. Information on psychology (Depression, Anxiety, and Stress Scale-21) and sleep (Functional Outcome Sleep Questionnaire-30) status was collected at pre- and post-experiment. The researcher-developed feasibility questionnaire was given to the participants in the intervention group at post-experiment. Repeated-measures analysis of variance was used to investigate within-between group comparison, and significance value was set at p ≤ 0.05. The analysis found potential improvement on sleep (p = 0.039) and psychological health (p = 0.002-0.067). The intervention protocol is feasible and highly accepted by the participants. The required optimum amount of dosage, sample size, and the use of outcome measures are suggested from the findings. This pilot and feasibility study supports the use of Xbox 360 Kinect games in practice and to be implemented for future research.
