FORCE FEEDBACK DEVICE INCLUDING ACTUATOR WITH MOVING MAGNET

摘要

A force feedback interface (200) is coupled to a host computer (202) that displays a graphical environment, the device including a user manipulatable object (14) physically contacted and moveable by a user. A sensor (226) detects a position of the user, where the sensor signal includes information representative of the position of the user object. An actuator (228) is coupled to the user object and outputs a force on the user manipulatable object. The actuator includes a magnet (45) and a grounded coil (50) and wherein a current is provided in the coil to generate the force.
