The Flystick2 is our widely-used wireless interaction device for standard VR applications with a protected passive target.
The Flystick2 has 6 buttons and an analog joystick. Up to 4 Flysticks can be used simultaneously. The wireless data transmission to the controller is guaranteed by a USB radio transreceiver in the ISM band. Flystick2 data can be received by trackd, VRPN, VR Juggler and most applications with direct interfaces.
