It looks like you need to press very hard. I expect that people's fingers will get tired and stiff.
Why not just take a picture of your paper? Ideally, they could just put some special markers on the corners of the page, and then a phone app could home in on those to properly focus and align the page. Problem solved.
The other thing is, why make the pen communicate with the device (e.g. tablet) in real time? This seems like a waste of power, and not practically useful [1]. You could simplify it by just having a button on your pen that, when you click, sends over the aggregated line data.
[1] I suppose one use case is to share in real-time with some kind of audience, but this is already a solved problem with a stylus on a laptop or tablet... why add the extra cost of special paper?
- psychometry 11y agoYou're basically describing this: http://whitelines.se/link/ http://whitelines.se/link/ I've bought the paper, which is nice, but haven't used the app.
- joshvm 11y agoI have a Leuchterm notebook with Whitelines. It's not bad, the app works reasonably well. It's just doing fiducial detection and some perspective undistortion, pretty much out of the box OpenCV.
- reitanqild 11y agoThis works excellent. Another reason to love it is they provide their app for free as well as downloadable and printable pdfs of their special paper. Seems they make money on the convenience of buying ready-made stacks of this paper as well as whiteboard magnet kits that allows you to use normal whiteboards with their app. (And yes, I love it and have occasionally used it but I am otherwise unaffiliated.)
- TheLogothete 11y ago>Why not just take a picture of your paper? Moleskine has this in partnership with Evernote. Onenote has an app called Office Lens. Additionally, this has already been done. Livescribe has the exact same product. By the looks of it, it's better.
