Meet the Kinect: An Introduction to Programming Natural User by Sean Kean

By Sean Kean

Meet the Kinect introduces the intriguing global of volumetric computing utilizing the Microsoft Kinect. you will learn how to write scripts and software program permitting using the Kinect as an enter machine. engage at once along with your desktop via actual movement. The Kinect will learn and music physique routine, and is the bridge among the actual fact during which you exist and the digital international created via your software program.

Microsoft’s Kinect used to be published in fall 2010 to turn into the fastest-selling digital gadget ever. For the 1st time, we now have a cheap, three-d sensor permitting direct interplay among human and laptop, among the actual global and the digital. The Kinect has been enthusiastically followed by way of a growing to be tradition of fans, who placed it to paintings in growing technology-based artwork initiatives, 3-dimensional scanners, adaptive units for sight-impaired members, new methods of interacting with computers, or even ecocnomic company possibilities.

Meet the Kinect is the source to get you began in learning the Kinect and the fascinating chances it brings. You’ll find out about the Kinect and what it might probably do. You’ll set up drivers and discover ways to obtain and run the becoming volume of Kinect software program freely on hand on the web. From there, you’ll movement into writing code utilizing a number of the extra well known frameworks and APIs, together with the authentic Microsoft API and the language often called Processing that's renowned within the paintings and artistic world.

Along the way in which, you’ll study ideas and terminology. Volumetric computing didn’t commence with the Kinect. the sphere is many years old—if you’ve ever had an MRI, for instance, you may have benefitted from volumetric computing expertise. Meet the Kinect is going past simply the only equipment to impart the rules and terminology underlying the interesting box of volumetric computing that's now wide-open and obtainable to the typical person.

The following section highlights the devices that are marketed for use in 3D natural interface systems. Because of the way these systems are designed, they have abilities that structured light systems are unable to match. Depending on the type of illumination employed and the 37 CHAPTER 2 BEHIND THE TECHNOLOGY availability of ambient light suppression, time–of–flight units can be used outdoors in daylight. Structured light systems are often unable to compete with the strength of light beyond indoor conditions.

Your shape is silhouetted because you are blocking the IR projector from placing measurable light on the wall behind you. It may not look like much, since this is a very rudimentary use of the technology, but you can get an idea of where this capability is leading when you check out Microsoft Research’s KinectFusion project for realtime dynamic 3D surface reconstruction. This ability to reconstruct the physical world in digital space is a major theme at Microsoft, and simple applications that have you “digitize your world” can be found in the Fun Labs minigames available from Xbox Live.

Some of the great “hacks” seen on YouTube work with just this raw data and don’t even go to the level of using the Kinect for gesture recognition. Microsoft Research’s debut of KinectFusion (Figure 1-25) at SIGGRAPH 2011, the leading industry conference for graphics experts, shocked many in the tech world. Previously, the volumetric video output from the Kinect was panned as too low quality to be useful. KinectFusion’s high-resolution, realtime, photorealistic reconstruction of people and objects, even with 27 CHAPTER 1 GETTING STARTED a shaky camera, demonstrated that a persistent model of an entire scene could be stored and updated rapidly to fill in missing detail behind the view of the camera.
