Meta-Trainer: An Augmented Reality Trainer for Home Fitness with Real-Time Feedback

Meta-Trainer allows people to train on their own, supervised by a virtual trainer that provides exercise samples and real-time feedback. The system relies on a set of smart glasses for Augmented Reality (AR), to enable users to interact with the virtual trainer in a hybrid environment. Given a target exercise, the virtual trainer demonstrates the movements to be reproduced. Differently from video-based applications, the user can move around the virtual trainer so as to look at the exercise from different angles for a more immersive and realistic experience. The AR glasses can also track head movements, which are then used to give feedback and track the training progress. This system offers an advancement compared to video-only trainers, not requiring the user to look at a screen while performing the exercise.
