Kinect in Motion - Audio and Visual Tracking by Example

Overview of this book

Kinect is a motion-sensing input device by Microsoft for the Xbox 360 video game console and Windows PCs. It provides capabilities to enhance human-machine interaction along with a zero-to-hero journey to engage the user in a multimodal interface dialog with your software solution. Kinect in Motion - Audio and Visual Tracking by Example guides you in developing more than five models you can use to capture gestures, movements, and voice spoken commands. The examples and the theory discussed provide you with the knowledge to let the user become a part of your application. Kinect in Motion - Audio and Visual Tracking by Example is a compact reference on how to master color, depth, skeleton, and audio data streams handled by Kinect for Windows.Starting with an introduction to Kinect and its characteristics, you will first be shown how to master the color data stream with no more than one page of lines of code. Learn how to manage the depth information and map them against the color ones. You will then learn how to define and manage gestures that enable the user to instruct the application simply by moving arms or any other type of natural action. Finally you will complete your journey through a multimodal interface, combining gestures with audio.The book will lead you through many detailed, real-world examples, and even guide you on how to test your application.

Summary


In this chapter we learned how to start building a Kinect project using Visual Studio, and we focused on how to handle color streams and depth streams.

We managed the KinectSensors_StatusChanged event handler to retrieve the potential active Kinect sensor and we learned how to start the sensor using the KinectSensors.Start() method.

Thanks to the KinectSensors.ColorStream.Enable(ColorImageFormat) and the event handler attached to the KinectSensors.ColorFrameReady, we started to manipulate the color stream data provided by the Kinect sensor. We then had some fun applying custom effects to the color stream data.

We went through scenarios where retrieving color frames using the KinectSensors.ColorFrameReady could cause issues, and we introduced the polling technique using the ColorImageFrame OpenNextFrame (int millisecondsWait) API instead.

We introduced the SDK V 1.6 new API ColorStream.CameraSettings for tuning the images provided by the Kinect sensor.

Using the ColorImageFrame.Format...
