About
|
- Open source framework
- Maintained by not-for-profit organization “formed to certify and promote the compatibility and interoperability of Natural Interaction devices, applications, and middleware"
- Provides API for “writing applications utilizing natural interaction”
- Communicates with low level devices and high level middleware
|
- core library for accessing Kinect camera
- maintained by OpenKinect community (2000+ members) – completely open source
- Large number of wrappers available: Python, C Synchronous, Actionscript, C++, C#, Java JNI, Java JNA, Javascript, Common Lisp
- Includes utilities to record Kinect data dump and simulate Kinect feed by playing recorded data
- Licensing: dual Apach v2/GPL v2
|
- Official SDK for interfacing with Kinect
- available for non-commercial use now, commercial package available later
- offers skeletal tracking and audio support, much like other drivers, but with a few differences
|

Features
|
- RGB / Depth Images
- Physical motors
- Accelerometer
- LED
- Audio output
Capabilities supported, implemented by middleware (usually NITE)
- Full body skeletal/blob data
- Hand tracking
- Gesture detection
- Scene Analysis (using depth sensing)
|
- RGB / Depth Images
- Full body skeletal/blob data
- Gesture Detection
- Physical motors
- Accelerometer
- LED
|
- Audio processing using four-element microphone array with noise & echo cancellation
- Sound source localization for beamforming/sound spatial location
- Depth data
- Raw audio/image data
- Skeletal tracking for up to 2 people
|
Pros:
|
- Large number of supported middleware and toolkits for skeletal tracking, gesture tracking, etc…
- Existing sample integration into Ogre, Unity
- Greater range of flexibility for integration with overlying toolkits
|
- Greater range of flexibility for customization
- Large supporting community enables fast development & bug fixes
- Easier to install on a wide range of platforms
- Comes pre-packaged with skeletal/gesture tracking capability
|
- Official support for Kinect based projects
- Allows access to microphone array (can combine with position tracking for greater accuracy)
- Does not require initialization pose (can can therefore also pick up targets easier if location is lost)
- May lead to eventual integration into other Microsoft products (XNA, Xbox 360 Community)
- Includes sample code & documentation
- Very easy to install
|
Cons:
|
- Can be difficult to install on non-Windows machines
|
- Not always supported by utility toolkits (FAAST)
- No audio access yet
|
- Only does skeletal tracking (no finger/hand gesture recognition yet)
- Skeletal tracking limited to 2 people
- Limited to Windows 7 systems
