1. A motion translating device for use in a tactile feedback system, comprising:
- a motion output device that imparts motion from a translator to a target area of a user'"'"'s skin;
a frame assembly, operable to translate motion from one or more actuators to the motion output device along at least a first axis and a second axis;
the frame assembly having associated therewith a motion decoupling apparatus, the motion decoupling apparatus being operable to translate motion between at least one of the one or more actuators and the frame assembly along one of the axes while at least partially decoupling motion between at least one of the one or more actuators and the frame assembly along an other axis;
wherein the motion decoupling apparatus comprises a slot formed in a member of the frame assembly, the slot having a larger dimension in a direction of a decoupled axis and a smaller dimension in a direction of a translated axis.

Abstract
A motion translating device for use in tactile feedback system comprises a motion output device, operable to impart motion from the translator to a motion output device. A frame assembly is operable to translate motion from at least one actuator to the motion output device along at least a first axis and a second axis. The frame assembly has associated therewith a motion decoupling apparatus. The motion decoupling apparatus is operable to translate motion between an actuator and the frame assembly along one of the axes while at least partially decoupling motion between an actuator and the frame assembly along an other axis.

6. A tactile display system, comprising:
-
a motion output device that engages a target area of a user'"'"'s skin; a restraining system that restrains a portion of the user'"'"'s skin adjacent the motion output device; an actuation system including one or more actuators, the actuation system being operably coupled to the motion output device and including; a first frame operable to translate motion from at least one of the one or more actuators to the motion output device along a first axis; a second frame operable to translate motion from at least one of the one or more actuators to the motion output device along a second axis; and each frame having associated therewith a motion decoupling apparatus, each motion decoupling apparatus being operable to translate motion between at least one of the one or more actuators and the frame along one of the axes while at least partially decoupling motion between at least one of the one or more actuators and the frame along an other axis. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method of translating motion from a pair of actuators to a motion output device of a tactile display, comprising:
-
coupling a motion output device to one of a pair of frames; coupling each frame to an actuator through a motion decoupling apparatus, each motion decoupling apparatus being operable to translate motion between the actuator and the frame along one axis of movement while at least partially decoupling motion between the actuator and the frame along an other axis of movement, wherein each motion decoupling apparatus comprises a slot formed in a member of the frame, the slot having a larger dimension in a direction of the decoupled axis and a smaller dimension in a direction of the translated axis. - View Dependent Claims (14, 15, 16, 17, 18)
