I have the leap motion but probably the old model (not sure).
I was able to use it this way to use hands as vive controllers, instead of the vive controllers, but the problem was the field of view of the leap motion being very narrow.
I was able use my hands just when in the range of the leap. U would lose the controller at the moment they were going off field. It was not really practical because the vive controllers are tracked by the vive base stations and hence they have a much wider range of use compared to your hands in leap motion.
The captogloves instead (when they will be fully implemented in vr) , i think, that they would be able to be tracked as the vive controllers, because of their captosensor in it.
Also, the original firmware of tpcast, I think, does not allow the leap motion to be wify/ wireless. So u would have a leap motion cable anchoring u to your pc.
Maybe the firmware made by a third party for tpcast, fixes the use of the leap motion wifi with tpcast. I did not try it
I also backed these gloves
that have their own sensor to mount on the headset and it would track the gloves for a big range
Do u guys know if the new version of the leap motion has a much bigger field of view/range?
