Bosch aims 6 axis inertial chip as VR and AR headsets

Bosch BMI085

Called BMI085, it is intended for virtual reality (VR) and augmented reality (AR) applications as well as navigation, body motion tracking and gaming.

“Its ultra-precise instantaneous detection of head movements reduces time lag to an almost imperceptible minimum,” said the firm. “The sensor is filled with features, combining a low-drift gyroscope with a low-noise accelerometer to significantly reduce the unpleasant motion sickness effect.”

Temperature coefficient offset (TCO) is typically <0.2mg/K and temperature coefficient sensitivity (TCS) is 0.002%/K. Bias instability of the gyroscope is typically below 2°/h.

“The gyroscope features closed-loop analogue-to-digital conversion, which ensures low drift characteristics even in high-fluctuation temperature environments,” claimed Bosch.

Accelerometer noise density is <120μg/√Hz, and data is synchronised across accelerometers and gyroscopes.

Packaging 3.0 x 4.5 x 0.95mm, pin-to-pin compatible with the firms earlier BMI055  for an easy up-grade.

BMI085 will be available for distributors end of May 2018.
