Low-latency inertial motion capture suits and sensors
The Yost Labs 3-Space™ sensor product line is a family of miniature, high-precision, high-reliability, Attitude and Heading Reference Systems (AHRS) / Inertial Measurement Units (IMU). Each Yost Labs 3-Space™ sensor uses triaxial gyroscope, accelerometer, and compass sensors in conjunction with advanced processing and on-board quaternion-based filtering algorithms to determine orientation relative to an absolute reference in real-time.
Yost Labs’ 3-Space™ sensors with QGRAD™ fusion firmware are establishing new benchmarks for low latency and high accuracy. These sensors output fully fused orientations at 850Hz (3x faster than sensors running a Kalman filter alone) providing the necessary low latency responsiveness needed for applications such as HMD tracking, drone stabilization, biomechanics analysis, and real-time robotic control. For calibrated IMU data, 3-Space sensors clock in at 1,350Hz. These impressive stats are the result of a decade of sensor fusion research and development. Yost Labs’ innovative work with 3-Space sensors has been recognized with several patent awards and numerous additional patents pending.
The product family offers an array of communication, performance, and packaging options ranging from the ultra-miniature TSS embedded to fully integrated battery-powered wireless and data-logging versions.Orientation can be returned in absolute terms or relative to a designated reference orientation. The proprietary multi-reference vector mode increases accuracy and greatly reduces and compensates for sensor error. The Yost Labs 3-Space™ Sensor system also utilizes a dynamic sensor confidence algorithm that ensures optimal accuracy and precision across a wide range of operating conditions.
The Yost Labs 3-Space™ Sensor system features are accessible via a well-documented open communication protocol that allows access to all available sensor data and configuration parameters using a variety of communication interfaces. Versatile commands allow access to raw sensor data, normalized sensor data, and filtered absolute and relative orientation outputs in multiple formats including: quaternion, Euler angles (pitch/roll/yaw), rotation matrix, axis angle, two vector(forward/up).
“We chose the 3-Space™ Embedded sensor for our medical product because of its ease of integration – it is the best product on the market” Medical Device Manufacturer (confidential) (NY)
“We tested every AHRS/IMU we could get our hands on, 3-Space™ sensors performed at or better then everything else, and was actually the lowest price” Director of Product Development, HMD manufacturer (CA)
