The public health potential of the current health apps for increasing physical activity

I consider my PhD as having 2 distinctive parts: A) to ascertain the quality of physical activity (PA) applications (apps) on the market in terms of safety, effectiveness, and user experience (Studies 1, 2); B) to assess the efficacy of selected PA apps with potential, physically inactive, users (Studies 3, 4). I am finalising part A of the PhD and I am writing the protocols for part B. It would be valuable to gain the views of experts to make sure I am considering the topic from both behaviour change discipline and user experience research

The potential of virtual reality (VR) and augmented reality (AR) to engage people with physical activity

Introduction: Sufficient physical activity (PA) reduces the risk of non-communicable diseases (NCDs) and improves physical and psychosocial health. The levels of PA in the UK and elsewhere in the world remain low for all age groups. Novel strategies for engaging people in PA are required to tackle the epidemic of inactivity. Virtual reality (VR) and augmented reality (AR) is computer-generated, interactive 3D environments that offer users unique immersive experiences of PA. / Aims: The aim of this mixed-methods, staged research project (vEngage) was to test the potential of VR and AR to engage people in PA. This work was a Medical Research Council (MRC) funded partnership between academic researchers (UCL, Coventry, and Anglia Ruskin Universities) and an industry partner ‘Six to Start’. / Methods: I surveyed and interviewed the users of the world’s most popular running app Zombies, Run! (ZR) (Studies 1 and 2). I then conducted a scoping review in a form of a qualitative analysis of game reviews on popular VR exercise games (exergames) and described positive and negative features, current players of VR exergames report, as important motivators for exergame playing (Study 3). In parallel, the vEngage team set up a steering committee of adolescents (13-17 years) and their parents and interviewed both groups about PA, VR, AR, and exergaming (Studies 4a and 4b). We used the results from these studies to inform our VR exergame intervention (a game called Walls - Study 5) which we developed together with expert games designers Six to Start. / Results: VR is a promising strategy for engaging adolescents in PA but barriers to use remain, including awareness, availability, affordability, and accessibility. The results showed people have a positive attitude to exergaming, with a preference for narratives (engaging story, role-play). This was particularly supported by both ZR studies, where the narrative was the most motivating factor for engagement in PA for all age groups. VR and AR exergaming can distract people from the negative aspects of performing PA such as pain or repetition. / Conclusions: This research project was the first VR study that used principles of co-design in creating a digital VR exergame intervention for adolescents, by engaging adolescents themselves in the exergame design. AR and VR exergaming has great potential to engage a wide range of people in PA and can be particularly useful as means for PA engagement in a time of world pandemics such as the recent Covid-19 pandemic, where gym and fitness facilities are not accessible for unspecified periods of time
