Gyro sensor motion capture.

The privacy risks associated with some sensors like a mi crophone eavesdropping camera or gps tracking are obvious and well understood some of the risks remained under the radar for users and application developers. Bunch of concerned applications have been mentioned pointing to the commerciality of the technology. In this section we look into the application of inertial sensors for tracking human motion. Wearable and mountable motion and environmental sensors.

Here different types are plotted by size and performance. Sensors for motion capture biomechanics industrial control robotics facility management cold storage research product development. It is used to determine the rotational orientation of the imu. The motion gyro compass from kongsberg is a maintenance free imo type approved motion sensor and gyro compass for navigation that in addition can serve other applications or solutions in need for attitude and heading input.

By subtracting the gravitational acceleration from the sensor frame the accelerometer can calculate the initial position. Besides sensing the angular velocity gyroscope sensors can also measure the motion of the object. Inertial motion capture uses imus inertial measurement units with built in sensors to detect position and movement. Xsens products include motion capture imu ahrs human kinematics and wearables.

In recent years vibration gyro sensors have found their way into camera shake detection systems for compact video and still cameras motion sensing for video games and vehicle electronic stability control anti skid systems. In particular access to motion sensors such as gyroscope and accelerometer is unmitigated by mobile operating systems. Gyro sensors come in a variety of types. Our sensors include an accelerometer gyroscope magnetometer barometer temperature and ambient light sensor.

Here we survey the relevant body of literature to develop our system. These typically include gyroscopes accelerometers and sometimes magnetometers. The gyroscope measures angular rate. For more robust and accurate motion sensing in consumer electronics gyroscope sensors are combined with accelerometer sensors.

Depending on the direction there are three types of angular rate measurements. The gyroscope in this motion sensor network measures the orientation of the sensor data that reflects gravitational acceleration. Principle of navigation systems based on inertial sensors.
