I'm always looking for the next note-taking device, and I got the idea it would be cool to combine a pico projector and a document camera, so I could project an image over my notepad and then just take a picture of it. This way I could, say, annotate web pages/pdfs with a real pen and scan quickly w/o having to rip the page. That's how I found this guy's work I posted a couple days ago [1]. Anyway, turns out HP has done the hard work for me. Now I just need to waste some $2k USD to verify my silly idea... :p 1: https://news.ycombinator.com/item?id=8502303 https://news.ycombinator.com/item?id=8502303
