Repeatable, wireless motion capture

SolitonReach sensors, originally developed at the Ohio State University, are a revolutionary inertial measurement unit (IMU) based motion capture technology. Other IMU-based sensor systems suffer from drift, making them unsuitable for high-precision repeated measurements. Similar sensor systems may be wired or have short battery life.

What is an IMU?

An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the magnetic field surrounding the body, using a combination of accelerometers and gyroscopes, sometimes also magnetometer. Using a special fusion algorithm, IMU sensors can be used to derive the relative movement of limbs, without requiring any cameras to track ongoing motion.
