Laptop turned multitouch

Very cool. I do have a simple question.

Could you do single laser tracking with touchlib with the 780nm laser similar to a digital whiteboard? If so, where is there some good information on this?

I know it's a silly question why one would want in IR laser for a digital whiteboard, but there is a specific reason.

Do you wear Eyeprotection while you use it?

[stragesv3]

@Flodice yes, thought the 120 degree line lens spreads out the beam a lot

[stragesv3]

@Flodice yes though the 120 degree line lens spreads the beam out a lot.

what program did you use?

[stragesv3]

@InsaneTux I believe I was using touchlib at the time which has since been superseded by Community Core Vision (CCV)

@jonidimo

he uses a line generator on the laser, this creates the laser light plane

[duncandude55]

this is just a average touch screen computer... no lasers or anything

[stragesv3]

@duncandude55 It is a Gateway tablet yes, but the model cx2610 is pen based and doesn't respond to touch. It does have a laser mounted to the upper left-hand corner of the screen.

What specs does the laser have ?

[stragesv3]

It's a 25mW 780nm (IR) laser with a 120 degree line lens from aixiz lasers.
