Startup Growl has unveiled a holographic AI trainer for home workouts. It will allow users to exercise from the comfort of their own home with the help of an interactive hologram of the trainer and impact surface. Growl utilizes powerful artificial intelligence and the Unreal Engine to create a realistic workout experience. The system is equipped with projectors that display a life-size image of the coach on a curved hitting surface, while 3D motion tracking analyzes the user's technique and provides detailed progress analytics.
