ultrasonic pen / light sabre
Friday, June 3rd, 2011Qualcomm’s ultrasonic pen demo transcribes from paper to device, now we have seen this type of thing before from livescribe where there is a micro dot camera used to identify a location on the page. That system uses, a special printed paper with tiny dots with codes on the paper, I’ve seen it in operation and it works well. The Qualcomm system seems to be different in that it uses triangulation with ultrasonic sensors to see where the pen is in the real world, or on the sheet of paper. I don’t think they will be any requirement for special paper.

They’ll probably be another survey out next week to say that they are safe!
