iisu Middleware

iisu® is a complete platform for natural gesture development and deployment. iisu offers full-body skeleton tracking as well as precise hand and finger tracking. It supports powerful legacy cameras such as the original Kinect, the Asus Xtion, the Mesa SR 4000, the Panasonic D-Imager and of course the SoftKinetic DepthSense 311 and DepthSense 325 (aka Creative Senz3D). iisu dramatically reduces development cycles by automatically loading the appropriate driver. iisu also offers advanced tools such as Toolbox to visualize human tracking using depth data and Interaction Designer to easily create your interaction. iisu supports Flash, Unity, C# and C++ environments.

Although iisu has been discontinued since the release of our specialized DepthSense Librairies, it remains the best solution to develop human body tracking applications using various depth sensing cameras.
