We know that Intel sees 3D cameras as the future of computing, and the company's Anil Nanduri just provided a few hints of what that future may involve. He tells Network World that the depth-sensing technology can recognize emotions, such as happy smiles. It can also track your gaze; a camera can detect when readers are stumped by unfamiliar words in a book, for example. The technology's shape detection is accurate enough that it can even scan objects for 3D printing. We won't get a true sample of the technology's potential until Creative ships its Senz3D camera before the end of the current quarter. Nonetheless, it's already evident that Microsoft's next-generation Kinect for Windows will have some real competition on its hands.
