FAQs:

Q: Why can't you see father than 10 meters away?

A: 1. Limited camera resolution 2. Limited bandwidth over USB 2.0 3. Baseline of plane




Higher resolution cameras, and USB 3.0 will allow detection at longer distances.


Q: Why not look at multiple depths, instead of just one depth?

A: These CPUs were maxed with just one depth, at 120 Hz More powerful CPUs are already on the market, and will enable multiple depths.
