Comments on: Touchlib’s AS3 TUIO library updated http://www.cyancdesign.com/2009/05/touchlibs-as3-tuio-library-updated/ Interactive Designer and Developer Mon, 10 Oct 2011 11:07:20 +0000 hourly 1 http://wordpress.org/?v=3.3 By: Chris Yanc http://www.cyancdesign.com/2009/05/touchlibs-as3-tuio-library-updated/comment-page-1/#comment-2560 Chris Yanc Wed, 08 Jul 2009 15:15:57 +0000 http://www.cyancdesign.com/?p=277#comment-2560 One of the main differences between the commercial products and self build ones is the way the software gets the information. Products like the HP touchsmart and touch sensative LCD monitors use a film that uses electricity or sound waves to calculate the distance from the edges. And the Touchlib and Community Core Vision software uses a webcam to collect the points of light on the surface compared to a calibrated grid to interpret the X Y coordinate. The information is then output, Touchlib and CCV use a specific protocol accepted by the community so we all work with the same information across multiple platforms. Commercial products usually make their own output protocol to work with an OS like Windows 7, it seems like the smart business thing to do. It is possible to hack into the commercial protocol and convert it to match the Touchlib/CCV protocol, I know I've seens videos of it done.

I was confused about this as it seems that touchlib and tmini seem to encourage users to build their own multitouch systems. thanks, Ben Hi Chris,
