AR - Fitness Form Check
Exploring a fitness app in augmented reality which would help trainers, friends to check form of exercises. In the near future, as we are getting close to having more AR hardware and software capabilities through Apple's ARKit and Google's ARCore, this could be used by someone wearing suitable eyewear. The interaction of tapping the button could be through eye-tracking.
This could also be extended to be used with a mobile phone. An example use case could be the person performing the exercise, puts the phone on a stand. The app would continuously monitor their form and notify (through audio notifications on their earphones) on form corrections.
