RPLidar S1 for multitouch

I’ve just got myself an RPLidar S1 from Slamtec and so far using RoboStudio I can see the scanning range is quite impressive with quite a not-so-bad object detection. I am wondering how feasible it is to use it for multitouch application, say mount in somewhere perpendicular to the display (projection or videowall) and make it detect finger and translate the detected position/blob as multitouch input?

I know there’s a bunch of ready solution using sensors from Sick or Leuze but given the expensive price tag (hardware+software), I am thinking maybe with this lower cost sensor, it could be an alternative. Of course, it’s only the hardware part while the software portion for this new sensor is basically non-existent.

Some brief todos for the software are:

Any comment or thought or pointer?

I’ll be R&Ding exactly this over the next few weeks for a commercial install.
Looking at using A2/A3 units from Slamtec, and will have 4 in a room one covering each wall.
Won’t be able to share code, but I’ll be happy to let you know how I get on…

For true multitouch you might need a couple of units covering the same wall so you can cover times when one touch point shadows another. I’ve not got this issue as I’m only looking for single touches.
Not sure if you’ll get interference from two units, I’m going to try that out once mine arrive.

@nebulus_design Im interested on this, ready made commercial solutions (hardware+software) are very expensive and this can be a good alternative.

Keep us updated!
