Sensor Fusion
Flexible 9-axis 6 DOF Solution for Android Devices
VTI’s Sensor Fusion combines sensory data and the strengths of each sensor to obtain accurate and complete easy to integrate motion sensing information for intelligent devices.
Sensor fusion is implemented by using 3-axis gyro, 3-axis magnetometer and 3-axis accelerometer connected to application processor running Android OS.
• Magnetic and gyro sensor are auto-calibrated
• Frequency response and noise performance can be optimized to meet application requirements
• Small memory footprint 12 kB and low <5%
processor load (OMAP4430) for the fusion
