The aims of this study were (1) to investigate eye gaze patterns of persons with ball sports experience, based on virtual augmentation during overhead target throwing and playing catch, and (2) to investigate the usability of the Mixed reality system for motor skills training through throwing and catching activities.
We used the Mixed Reality Tool Kit (MRTK) system, in which we combined a HoloLens2 smart glasses (Microsoft Corporation) with a motion recording capture system.
The MRTK system has the potential to provide motor skills training and to assess the eye movement pattern outside of the clinic. This initial investigation of mixed reality (MR) motor skills training may aid in the development of not only motor skills, but also social skills such as eye contacts and reading facial expression with all children, including those with developmental disabilities.
Safety,Efficacy
There are two trials we are going to investigate. The first trial was the target throwing task during which each subject was wearing a HoloLens2 to view the virtual target and was allowed 10 throws to try to hit them. The second trial was the playing catch task, which required each subject to throw and catch a ball 10 times. All trials were recorded with HoloLens2 to gather eye gaze data, and digital video cameras to gather skilled movement data. The subjects' eye tracking patterns, as well as the usability and safety of the HoloLens2 in motor skills training, were evaluated.
