Polhemus has launched the G4 wireless 6 Degree-Of-Freedom motion tracker. G4 is capable of being belt-worn. It has sensors operating at 120 Hz. G4's hub calculates each sensor's position and orientation, and then wirelessly reports the information directly to the PC.
Incorporating digital signal processor (DSP) electronics, in concert with AC magnetics, allows data stability, high resolution and speed to be achieved, according to the company. G4 contains all the necessary processing hardware. The company says the rechargeable lithium-ion battery has 10+ hours of battery life. For more information, visit Polhemus.
