Hi All -
My studio is developing an interactive activation that will require multiple skeleton tracking (probably 4-6 people). The experience will be approximately a 10’x10’ footprint (still in the works) and will use gestures (mostly arm waving) to affect elements on a large display on one end.
The audience will be a full range of body types / heights, as it is for kids, who may also have adults with them (not sure how much this matters).
Basically, I just wanted to get any thoughts on which camera(s) to use and if there are any technical hurdles I should expect.
Thanks!
Hi Steve,
For this type of application, I always recommend the ZED 2i camera.
It’s a USB camera with a wide angle which is very nice for interactive experiences.
With 4 to 6 people in such a small area, you might need to use more than one camera to prevent any occlusion and tracking loss.
For mainly arm tracking, I’d say 2 cameras should be enough with one on each side.
To have the best tracking quality, you need to make sure :
- What you need to track(the arms in your case) are always visible by at least one camera. That is why I recommend using a second camera.
- The lighting conditions are good. Indeed, our body tracking module is fully based on the RGB image so the tracking quality can greatly decrease in low-light env.
You can completely start with only one camera to see how it goes and update to two later if needed.
Here are some links to our documentation:

Let me know if you need anything else.

I meant front and back, sorry.
We have ready-to-use samples/demos in Unity to demonstrate the tracking features but you need a camera to test it.
