Mixed Punch Bag is a virtual reality training for advanced (!) martial artists to train with a real punch bag in vr. You can set the dimension of your real punch bag (or a wall). There are targets on your punch bag to be hit with fists and elbows. Furthermore the training includes defensive objects for dodging and blocking.
Here is the video from the first test training of the new unit mixed punch bag with the Oculus Quest. It was a little improvised recorded because of the lockdown, better recordings will follow.
Interest, but be carefully!
