Earlier this week I traveled to Microsoft’s Mountain View campus to play with the company’s new Kinect sensor. While there I met with a few of the team’s engineers to discuss how they had built the new device. Up front, two things: The new Kinect sensor is far cooler than I expected. Also, I touched an Xbox One. The story of the Kinect device, both its first and second generations, has been a favorite Microsoft narrative for some time, as it fuses its product teams and basic research group in a way that demonstrates the potential synergy between the two. The new Kinect sensor is a large improvement on its predecessor. Technically it has a larger field of vision, more total pixels, and a higher resolution that allows it to track the wrist of a child at 3.5 meters, Microsoft told me. I didn’t have a kid with me, so I couldn’t verify that directly. It also contains a number of new vision modes that the end user won’t see, but are useful for developers who want to track the human body more precisely and with less interference. They include a depth mode, an infrared view, and new body modeling tools to track muscle use and body part orientation. When in its depth image mode, acting as a radar of sorts, each of the 22,000 pixels that the Kinect sensor supports records data independently. The result is a surprisingly crisp mapping of the room you are in. The new Kinect also contains a camera setting that is light invariant, in that it works the same whether there is light in the room or not. In practice this means you can Kinect in the dark, and that light pollution – say, aiming two floodlights directly at the sensor – doesn’t impact its performance. I did get to test that directly, and it worked as promised. No, I don’t know the candlepower of the light array we used, but it was enough to suck staring into directly. So, developers can now accept motion data from the Kinect without needing to worry about the user being properly lit, or having their data go to hell if someone turns on the overhead light, or time sets the sun. The new Kinect also supports new joints in its skeletal tracking, in case you need to better watch a user’s hands move about. The smallest object
