Inertial measurement units (IMUs) are what robots use to keep upright and to navigate indoors where there are no GPS signals. Now an IMU-on-a-chip is being proposed to track both linear and rotational motion in devices like gaming or remote controls. Look for full 3D remote controls and gaming controllers to roll out this year and next. R.C.J.
MEMS chip maker InvenSense Inc. said it has integrated an IMU on a chip using a digital motion processor (DMP) that performs 6-axis sensor fusion of an internal 3-axis gyroscope and an external 3-axis accelerometer. IMUs enables motion processing without adding system processing overhead, said Michael Maia, vice president of InvenSense's Gaming and 3-D User Interface Business Unit. He said its IMU-3000 reduces power consumption whie easing integration into gaming controllers and 3-D remote controls.
