10. HiBall Sensor • Optical Sensor • 6 Lateral Effect Photodiodes, 6 lenses – 26 views • Overcomes most ‘line-of-sight’ problems • 150º Field of View • ‘Inside Out’ Tracking for great accuracy/sensitivity around the subject

11. Beacon Array Strips • Arrays of Infra-red LEDs – 8 per strip • Strips easily mount to ceilings • 6 Strips per 8 square feet • 300 Strips for 20ft. X 20ft. (~ 6m X 6m) • Scaleable to 40ft. X 40 ft. (~12m x 12m)

12. HiBall Stylus • Single button stylus • Calibrated for accurate measurements • Modular pointer • Standard HiBall Sensor mount

13. Software • HiBall Server • Controls entire system • Runs on HiBall PC controller • Provides Ethernet connection for data • VRPN (Virtual Reality Peripheral Network) • Interface to HiBall Server (and other peripheral devices and applications) • Public domain software from UNC-Chapel Hill • Available at http://www.cs.unc.edu/Research/vrpn/ • Sample Clients – track sensor, stylus

14. Technology • Autocalibration • SCAAT Algorithm

15. Autocalibration • HiBall system continually refines Beacon positions • Installation of Beacon strips requires no special calibration. • Image is 20ft x 20ft • Blue = ideal LED positions • Red = ‘actual’ LED positions determined by autocalibration

16. SCAAT • Single Constraint At ATime • Typical optical tracker requires 3 locations to triangulate • SCAAT updates tracker with a single LED location • Provides accuracy, high update and low latency

17. HiBall-3100 Wide-Area Tracker Summary • High update rate • Low latency • High accuracy • Low jitter • Scales to 1600 sq. ft. (148 sq. m.) • 1 – 4 Sensors • Easy installation – autocalibration • For VR, AR, VIZ/SIM, industrial tracking, industrial measurement. Simply the industry’s highest performance wide-area tracker.
