Questions
How accurate is it compared to graphics tablets
From 1 comment
Very cool! It has the added benefit of being able to manipulate objects in 3d. How does it compare to graphic tablets in terms of accuracy?

How much does it cost, especially the pressure sensor
From 1 comment
Very cool! Could be useful for robotics / VR as well. One-camera hand tracking anyone? Question: could you use gyro+accel to track pressure as well? Or at least "taps"? Another…
