IPen: the first active stylus for iPad by Cregle Inc. — Kickstarter
- drcode 15y agoIf you look at the video, it looks like the technology is quite ingenious: Apparently, there's some kind of camera in the pen, and there's a little jiggling cursor on the the screen- The Camera and jiggling interact to pinpoint the pen position (apparently) down to a single pixel. This pen should be _extremely_ accurate... what I worry about is how quickly you can move the pen.
