In the three months since Beta 2, there have been many improvements to the SDK and runtime, including:
- Support for up to four Kinect sensors plugged into the same computer;
- Significantly improved skeletal tracking, including the ability for developers to control which user is being tracked by the sensor;
- Near Mode for the new Kinect for Windows hardware, which enables the depth camera to see objects as close as 40 centimeters in front of the device;
- Many API updates and enhancements in the managed and unmanaged runtimes;
- The latest Microsoft Speech components (V11) are now included as part of the SDK and runtime installer;
- Improved “far-talk” acoustic model that increases speech recognition accuracy;
- New and updated samples, such as Kinect Explorer, which enables developers to explore the full capabilities of the sensor and SDK, including audio beam and sound source angles, color modes, depth modes, skeletal tracking, and motor controls;
- A commercial-ready installer which can be included in an application’s set-up program, making it easy to install the Kinect for Windows runtime and driver components for end-user deployments;
- Robustness improvements including driver stability, runtime fixes, and audio fixes.
