Terms of the deal were not disclosed, but Silver Lake's private investment firm typically makes large scale investments and most recently participated in Groupon's massive $950 million round of financing.
The Israeli startup's name has been overshadowed by Microsoft and its highly popular Kinect device, though the device's success proves the viability of gesture recognition technology. The PrimeSense name will become more widely recognized once the technology, which is capable of tracking both body movements and gestures, becomes a part of more applications and moves into new markets.
The startup demoed its latest developments in 3-D gesture control at CES. PrimeSense technology is being integrated into TV sets, set-top boxes and computers to allow users the ability to interact with and control devices.
"The company is the global leader in gesture technology with a talented management team, experienced board, and partnerships with some of the world’s premier technology companies," said Paul Mercadante, managing director of Silver Lake Sumeru. "We look forward to working with PrimeSense to realize its significant growth potential."
