Last year, Hillcrest Labs (Rockville, Md.) announced the integration of its MEMS sensor algorithms—the Freespace MotionEngine—with Broadcom Corp.'s digital-TV on-a-chip and Bluetooth on-a-chip, as well as major design-wins with the LG's Smart TVs, SMK's Smart TV remotes, and most recently for the second-generation of the popular Roku set-top box for Internet protocol television (IPTV). The company also licensed its intellectual property to Playstation-maker, Sony Corop. and "amicably resolved" a dispute with Wii-maker Nintendo Corp. regarding its motion-processing algorithms.
The latest incarnation of the Freespace MotionEngine has also improved its modularity, enabling OEMs to run its motion-processing algorithms inside the remote control itself, in the USB dongle that wirelessly communicates with the remote, or on the application processor inside the Smart TV, gaming console, mobile phone or other device.
"As we gain more design wins for a greater variety of devices, we needed to make the Freespace MotionEngine more flexible," said Lucien. "For instance, now Smart TVs can run the gesture recognition algorithms on their own application processor, thus cost-reducing and extending the battery life of their remotes, which now just have to transmit raw sensor data from the MEMS chips."
Hillcrest is also offering pre-assembled sensor modules complete with MEMS accelerometers, gyroscopes and magnetometers, plus a microcontroller running the Freespace MotionEngine, for easy integration into their own gesture-based remotes. Or OEMs can choose to license its Scoop Pointer, which is a complete reference design for gesture-based remote controls. The Scoop Pointer even includes a red-laser pointer so it can also be used for air-mouse applications where presenters choose menu items on-screen as well as to point out items with the laser pointer.
Hillcrest also recently updated its free Kylo web browser to allow OEMs to modify it when creating smart-remote control applications using the Freespace MotionEngine with computers.
