Introduction
Today's e-classroom includes many new technologies from audio/video streaming to the audience outside the classroom, teachers using digital projects, to students writing notes on their TabletPC. These technologies provide more efficient flow of information. However, one barrier such technology always has to face is a person who prefers the old fashion way (i.e. for a student this is the use of pen and paper). My project realizes one idea to over come such a barrier by jumping over it rather than hitting it head on. I introduce you to the idea of a digital pen.
Digital pen is a project, which uses a camera that is built into the pen and a specially designed lined paper. This enables the user to do their old fashion writing with an additional feature, which uploads all the information about the pen movement on paper and the paper itself to a laptop computer. The laptop computer must run specialized software that gathers the information delivered to it via USB link and stitch it together. The result is a real-time digital copy of the user's handwriting and drawing stored on their computer.
Video
Demo video is available here. Note that it is fairly low quality compressed with MPEG4 and size is 773 KB. In it you can see captured images from the software. The first part shows linear and non-linear transforms while the second part shows only non-linear transforms. The second part produces much nicer results for obvious reasons explored else where on this site.
