The short answer: yes. But (there’s a but). I’ve tried using Touch controllers (or Vive’s) and the thing is that by doing so you necessarily occlude some fingers, which is a bad thing for Leap. So you could, but you’ll have a bad tracking of the fingers most of the time. Not recommended. For that solution would be probably something like tracked/haptic gloves. The fun with the Leap is that you don’t have any controllers (at the expense of having fewer mapped inputs)…
