Please let me know if I should narrow this down more from the page that I will give a link to.
This question is about positioning systems on athletes’ bodies. I don’t know if the way I’m planning on making a dance qualifies as a sport, but I think I might be able to use technologies used with sports in a dance. I think technologies used with the discus throw might help me overcome the problems of accuracy/precision and line-of-sight that I think I’ll run into. At this time, instead of inertial sensing, I’d like to try electronics (on parts of thrower’s/dancer’s bodies) working together with other electronics (external to what is on their bodies), as part of a positioning system.

So, how are you planning to proceed? Do you want to use an MPU-6050?
Thank you for your reply. I’m a beginner, so I don’t know if absolute positions can be used, but I’d like to know if absolute positions can be used. As far as I can tell, the MPU-6050 doesn’t use absolute positions, but rather inertial sensing. Is that right? Is there a better way than with absolute positions?

Maybe something like this would work for you?
Thank you. That is inspirational, but might be more than I need now. It would involve only two sensors (many of which are shown in the video that the first link that you gave me goes to) on one or two dancers’ costumes and a latitude and longitude (which would be a third point, point C). The size of an angle made by those three points could show how much part of a dance costume (or how much a ray that begins at a part of one dancer’s costume and intersects a part of another dancer’s costume) is towards point C. Why did the video mention sensors and not beacons, or something else?

Try googling them to get their contact info, then call or email them.
I tried, unsuccessfully, by sending emails to their library, marketing department, and orthopaedics department.
Why is it so hard for me to find out how to measure the location of body parts using absolute (instead of relative) positions? If I understand correctly, absolute positions require an external reference. For more on absolute positions, please see https://en.wikipedia.org/wiki/Positioni … al_sensing.
