The document is about the Intel Perceptual Computing SDK. It provides the following key details: - The SDK contains algorithms and modules for hand and finger tracking, face recognition, voice recognition, and 3D object tracking. It includes both low and high-level APIs. - The SDK can be used to create natural user interfaces using gestures and voice as well as for manipulating 3D content and games. - An optional Creative camera is available for purchase to enable some of the SDK's capabilities like hand tracking. - The SDK includes samples, documentation, libraries and headers to allow developers to integrate its capabilities into their applications.
