Overview of this book

Kinect has been a game-changer in the world of motion games and applications since its first release. It has been touted as a controller for Microsoft Xbox but is much more than that. The developer version of Kinect, Kinect for Windows SDK, provides developers with the tools to develop applications that run on Windows. You can use this to develop applications that make interaction with your computer hands-free. This book focuses on developing applications using the Kinect for Windows SDK. It is a complete end to end solution using different features of Kinect for Windows SDK with step by step guidance. The book will also help you develop motion sensitive and speech recognition enabled applications. You will also learn about building application using multiple Kinects.The book begins with explaining the different components of Kinect and then moves into to the setting up the device and getting thedevelopment environment ready. You will be surprised at how quickly the book takes you through the details of Kinect APIs. You will use NUI to use the Kinect for Natural Inputs like skeleton tracking, sensing, speech recognizing. You will capture different types of stream, and images, handle stream event, and capture frame. Kinect device contains a motorized tilt to control sensor angles, you will learn how to adjust it automatically. The last part of the book teaches you how to build application using multiple Kinects and discuss how Kinect can be used to integrate with other devices such as Windows Phone and microcontroller.

Skeleton smoothing – soften the skeleton's movement


At the beginning of this chapter we have discussed that skeleton processing is one of the most complex features because of its internal algorithm, data structures, joints representation, and data processing. Over this chapter you have gained a good understanding of skeleton data and while playing around with the applications you must have realized that the joint movements are not that smooth and there is some jitter present. Overall, this shaky movement of skeleton data does not provide a good end user experience and we need to overcome this problem to enable a rich user experience.

What causes skeleton jitters

Though the skeleton jitters could be caused by the application performance due to both software and hardware, there are several internal possible reasons for skeleton joints jittering. One of the main reasons is processing large amounts of data over a period of time during skeleton tracking. Because of the processing of large data...
