Force feedback interface (14) embodiments for providing low cost force feedback for enhancing interactions in a computer generated environment. One embodiment provides an actuator (30) in a non-primary axis or degree of freedom that outputs a linear force on the user object in non-primary linear axis that is not used to control a graphical object, and movement in the non-primary degree of freedom is preferably not sensed by sensors (28). The force sensations can be output in a direction perpendicular to a planar degree of freedom, radial to spherical degree of freedom, and/or along a lengthwise axis of the user object. A different embodiment provides a mouse movable in a planar workspace, where an actuator (30) coupled to a mouse button applies an output force in the degree of freedom of the button. Alternatively, a cylindrical member that may be rotated and translated can include a command sensor detects motion of the cylindrical member pressed down by the user, and an actuator (30) applies an output force in the pressed degree of freedom. |
