The driveBAY™ and trakSTAR™ electromagnetic (EM) 6DoF tracking solutions from Ascension Technology Corporation (an NDI company) provides cost-effective, high accuracy position and orientation tracking technology for integration into the most innovative and realistic medical training and surgical rehearsal simulators and military flight and gunnery simulation systems. Miniaturized, lightweight sensors embedded into medical instruments, helmets or Head Mounted Displays (HMD) track the user’s movements in all six degrees of freedom (6DoF), with no line of sight requirements. Every movement within the tracking volume, no matter how subtle or precise, is tracked in real time to exceptional accuracy. This accuracy, combined with low latency and fast update rates, allows sensor position and orientation data to integrate seamlessly with the simulator display to produce interactive training that’s remarkably true to life. A configurable design, small hardware footprint, and ease of integration further complement this 6DoF electromagnetic tracking technology solution known for its high value and high performance.
