Free-space navigation

The remote control includes a three-axis gyro and three-axis accelerometer combo circuit that can be used as a free-space navigation sensor, enabling the user to move a mouse cursor through gesturing with the remote control.

The gyro and accelerometer combo circuit is the ICM-20608 from InvenSenseĀ®. The gyro and accelerometer circuit is used as an input device for a SmartMotionĀ® firmware library from InvenSense that is integrated into the Smart Remote 3 firmware. Output data from the InvenSense library is fitted into a HID mouse report and sent to the host.

Note: The in-air pointing functionality is only provided as precompiled HEX files. To use the SmartMotion library in your design, please contact InvenSense or visit the InvenSenseĀ® Developers Corner (sign-up required).
