5 pressure sensitivity idea... - ID: 2871058

Last Update: Comment added ( gck1970 )

Details:

This would only work with hard surfaces, but what about if you hacked a
pressure sensor behind the IR-LED that adjusted it's brightness? The harder
you press the brighter the light gets? I know this would probably also have
issues with the angle of the pen, etc... any thoughts?

Date: 2009-11-06 12:52 Sender: gck1970 Sure it detects brightness. 4 bits worth, ie. 16 brightness levels. Extended Mode In Extended Mode, the IR Camera returns the same data as it does in Basic Mode, plus a rough size value for each object. The data is returned as 12 bytes, three bytes per object. Size has a range of 0-15. Since the "size" is referring to blobs of IR light which we know for this application would be coming from an LED of fixed physical size and a distance to the camera which is roughly unchanging then yes those size values could be interpreted as being the brightness level of the LED.

The only way I see this working is for the pen to have some kind of wireless capability with the computer sending pressure values back to the computer. This would be a lot harder to program (as it is completely separate) and expensive. But we can always hope :) Kory
