Leap Motion is a company most famous for building a gesture-recognition doodad for PCs that wound up integrated into keyboards. Since then, however, it has built ever-smarter sensors that can bring hand gestures to VR without the use of dedicated controllers. Now, the outfit is taking its biggest ever, er, jump by announcing Project North Star, a proposed augmented reality headset it plans to open-source next week. In a blog post, co-founder David Holz explains that the advent of AR is, at some point, going to become a pretty big deal. Consequently, the company has developed its own Hololens-esque device, albeit with a tasty-looking spreadsheet.
