| + | - Enable body tracking in the Settings of your Quest | ||

| + | Body tracking is done on the Quest using an AI model applied on the cameras built into the headset. The software runs on the headset itself so DEMoCap does not have to do this processing itself. Nevertheless body tracking on the Quest does reduce performance to some degree. | ||

| Since the quest only can use reliably the floor distance of the headset it calculates the body proportions solely from it. In general the floor height of a Quest is your own height minus 8-10cm. Hence you can measure your own height and then fill in the values as follows: | Since the quest only can use reliably the floor distance of the headset it calculates the body proportions solely from it.

| - | As mentioned above the simulated WiVRn trackers of unfavorable. In particular the elbow tracker is located at the elbow but with the orientation of the lower arm instead the orientation of the upper arm. If you use these simulated trackers directly you will get bad poses, for example the elbow spread depending on your lower arm bending instead of your upper arm position. | + | |
