Microsoft is reported to be buying 3D digital camera company 3DV Systems for $34m, giving it remote gesture recognition technology. Israel-based 3DV Systems is a venture capital-backed startup that has raised about $38m from investors. The company was founded in 1996 by two Israeli defence industry scientists who had worked on electro-optics technology for missiles. They developed and patented technology that could work out the depth relationships of objects in a digital camera’s field of view, in real time with high resolution. This was embodied in a chipset and in the ZCam 3D camera product range, now available in web-cam format.
