Thanks to its quartz-based QMEMS sensor technology, the Epson IMU is approximately 100 times more accurate than low-cost IMU technolgies used in consumer products. The Epson IMU has six degrees of freedom - a tri-axis gyroscope and a tri-axis accelerometer - that allow it to measure and control motion in three dimensions.
