Abstract: An analog joystick interface system for overcoming the deficiencies of the conventional analog joystick interface by supporting positional tracking in both a legacy and an enhanced mode. In the legacy mode, the host calculates the relative physical orientation of a positional grip of an analog joystick by relying upon continuous polling techniques. In the enhanced mode, a watch dog timer relieves the host of the need to continuously poll by directly providing the host with positional data concerning the relative physical orientation of the positional grip. The ability of the joystick interface to provide both the legacy and enhanced modes ensures that compability issues concerning the legacy DOS-based software applications and CPU allocation problems associated with continuous polling are resolved without considerably increasing cost or complexity of the joystick interface.
