Hy-BIRD fuses optical and inertial technologies into one compact tracking solution. Its primary optical technology outputs highly accurate, fast tracking data. A fully integrated inertial tracker seamlessly continues tracking whenever the optical scanner is blocked or its field of view exceeded.
APPLICATIONS
Helmet Tracking
Simulators & Trainers
Virtual Reality
Military Vehicles
Situational Awareness Systems
Biomedical Instrument Registration and Gating
Biomechanical Measurement and Analysis

Hy-BIRD is composed of an optical scanning unit with embedded electronics (above) and two head-mounted sensors - optical and inertial. The optical sensor can be seen in the right foreground. Optical and inertial data streams are fused and transmitted to a host computer via a USB serial adapter.

FEATURES & BENEFITS
240 optical measurements/second; 70-75 measurements/second in hybrid mode: Fast updates with no discernable lag
Full 360° coverage; no FOV limits: Smooth, continuous orientation tracking even when optical detector is occluded or its FOV exceeded
IR laser scanning technology with temperature compensated, calibrated inertial sensors: Accurate, undistorted tracking in fixed, motion-based and mobile environments
Built-in optical correction for inertial drift: Constant data flow without jumps or interruptions
Small footprint for emitter and detectors: Easy set-up with minimal impace on cockpit/vehicle real-estate
Fast, one-time calibration for misalignments: Flexible placement of optical and inertial sensors on helmet
