We've been hearing a lot about motion tracking as of late, the Leap Motion being the most popular device that is making its way to the public. However, a new mechanism is looking to gain some ground and has popped up on Kickstarter. The DUO 3D sensor claims to be the "world’s first and only DIY 3D sensing solution."
The DUO 3D sensor is open source, meaning that you can do anything with it that you please. It comes with open hardware plans, and you can get it in kit form where you assemble it or you can get fully assembled devices. The drivers and SDK are also open source, so there's quite a bit that you can do with it right off the bat.
The company even claims that the sensor is practically plug-in-play, where you just plug it in, download the necessary software, and start playing around with it "within minutes." From the video itself, the DUO looks to be extremely accurate, tracking fingers with every slight move. From the looks of it so far, it'll definitely give the Leap Motion a run for its money.
The "DIY" portion comes into play with the open source hardware blueprints that you can purchase (or "back" in this case). The hardware plans will provide you with everything you need, but it'll be up to you to get the parts and assemble it. However, you can modify the plans however you wish and truly make it your own.
Pledging $10 gets you the SDK, while $20 will get you the hardware plans, as well as the SDK. $40 will get you everything previously, as well as a custom-molded case for your 3D sensor. $140 will get you a fully-assembled kit, while $110 will score you all the parts you need to assemble it yourself.
