From VR Medicine News–Researchers based in Italy have investigated head-mounted displays for home use and their potential effects on users. Specifically, they evaluated outcomes in knowledge gain, self-efficacy, engagement, and presence over a period of 2 weeks, which they point out is a longer period than that measured in previous studies. The results suggest that the type of headset used did indeed affect outcomes.
