Dynamic accommodation is affected after performing an executive function task in mixed reality
Ellen Svarverud · 2022
Use of mixed reality (MR) displays in education and training have become increasingly commonplace. However, the inherent vergence-accommodation conflict (VAC) causes concern that usage of these technologies may have an effect on vision. We investigated dynamic accommodation in young adults before and after performing an executive function task in MR (Hololens 2). We found large differences in accommodation before and after performing the task for some individuals. We hypothesize that these changes could be an effect of the VAC and that using MR over longer time periods could be disadvantageous for some, while for others it may be increasing flexibility in the vergence-accommodation system. This emphasizes the importance of understanding individual visual characteristics when incorporating virtual displays into education and training.
