This invention describes an augmented reality system designed to help people learn or practice movement sequences, such as physical therapy exercises. It works by showing a virtual training object, like an avatar, performing a specific movement overlaid onto a live video feed of the user. The system then tracks the user's motion using both the video and multiple physical sensors attached to the user's body, specifically measuring acceleration, incline, and height at various points. Based on the user's performance, it can suggest new, more advanced routines.
Why it matters: Since 2018, consumer AR hardware and smartphone processing power have significantly advanced, making real-time AR overlays and image-based motion tracking more robust. However, the claims' specific requirement for multiple dedicated body sensors and a sensor hub remains a hardware integration hurdle for mass market products.
