Using a projector is a smart approach, as you aren’t punching a display, which means that you can’t break it.
“That’s the beauty of our technology. We mostly use light, and you’ll never break light,” Desrumaux said.
On each side of the frame, there’s one speaker and two cameras with infrared sensors. There’s also an additional camera near the top of the frame, along with some time-of-flight sensors.
The cameras and sensors are used to calculate the impact zone of your punch and your posture. The accelerometers behind the boxing bag are used to calculate the intensity of the punch.
“The core feature of our product is that we reproduce the physical presence of a one-on-one coach, as if they were physically there with you,” Desrumaux said.
