The method may include providing signals to an electronic interactive device, the device including an array of micro-step motors for contacting a skin surface of the subject and converting the signals to provide input signals to the array of micro-step motors. Haptic feedback may then be provided to the skin surface of the subject in response to the input signals. Exemplary micro-step motors may include two clutching actuators separated by a lateral actuator, each actuator adaptable to operate independently of the other actuators, and a shaft having a motion defined by movement of at least one of the lateral or clutching actuators.",
  "claims": [
    "1. An electronic interactive device comprising: a first surface; an array of micro-step motors, each motor including: two clutching actuators separated by a lateral actuator, each actuator adaptable to operate independently of the other actuators, and a shaft having a motion defined by movement of at least one of said lateral or clutching actuators, an end of said shaft being in contact with said first surface; and circuitry for receiving signals that provide an input to said array of motors configured to provide haptic feedback in response to said input. 2. The device of claim 1 wherein the first surface comprises a material selected from the group consisting of latex, cloth, neoprene, silicone, polyester, flexible polyvinylchloride, nitrile, ethylene vinyl acetate, ethylene propylene diene monomer rubber, viton, polyether, foam, rubber, fluorosilicone, polycarbonate, cork, nomex, kapton, plastic, elastomers, reversible material, and combinations thereof. 3. The device of claim 1 wherein the lateral and clutching actuators are piezoelectric actuators. 4. The device of claim 1 wherein the device is selected from the group consisting of a garment, touchpad, touchscreen, display, keyboard, tool, button, glove, suit, shirt, hat, goggles, spectacles, shoes, pants, socks, undergarments, clothing accessories, necklaces, bracelets, jewelry, and combinations thereof. 5. The device of claim 1 further comprising one or more transponders adaptable to interact with an incident signal thereon to produce a second signal, wherein the second signal is used to track movement of said transponders. 6. The device of claim 1 wherein the circuitry further comprises a flexible printed circuit board. 7. The device of claim 1 wherein said movement is a function of voltage. 8. A method of providing haptic feedback to a subject comprising the steps of: providing signals to an electronic interactive device, the device including an array of micro-step motors for contacting a skin surface of the subject; converting the signals to provide input signals to the array of micro-step motors; and providing haptic feedback to the skin surface of the subject in response to the input signals. 9. The method of claim 8 wherein each of the micro-step motors in the array further comprise: two clutching actuators separated by a lateral actuator, each actuator adaptable to operate independently of the other actuators; and a shaft having a motion defined by movement of at least one of the lateral or clutching actuators. 10. The method of claim 8 wherein the device is selected from the group consisting of a garment, touchpad, touchscreen, tool, display, keyboard, button, glove, suit, shirt, hat, goggles, spectacles, shoes, pants, socks, undergarments, clothing accessories, necklaces, bracelets, jewelry, and combinations thereof. 11. The method of claim 8 wherein the signal are provided to the device wirelessly or via a wire or cable. 12. The method of claim 8 further comprising the steps of: providing one or more transponders on the device; and tracking movement of the device as a function of signals provided or reflected by the one or more transponders. 13. The method of claim 8 wherein at least one of said input signals is a stepping voltage signal. 14. An apparatus for delivering haptic stimuli to a skin surface of a user comprising: an array of micro-step motors for contacting said skin surface; and a printed circuit board connected to said array for independently providing electrical signals to each of said motors in a predetermined sequence. 15. The apparatus of claim 14 wherein each of the motors further comprises: two clutching actuators separated by a lateral actuator, each actuator adaptable to operate independently of the other actuators; and a shaft having a motion defined by movement of at least one of said lateral or clutching actuators, an end of said shaft being in contact with said skin surface. 16. The apparatus of claim 15 wherein the lateral and clutching actuators are piezoelectric actuators. 17. The apparatus of claim 14 wherein the printed circuit board is flexible. 18. The apparatus of claim 14 further comprising a layer of material intermediate said array and skin surface. 19. The apparatus of claim 18 wherein the material comprises at least one of latex, cloth, neoprene, silicone, polyester, flexible polyvinylchloride, nitrile, ethylene vinyl acetate, ethylene propylene diene monomer rubber, viton, polyether, foam, rubber, fluorosilicone, polycarbonate, cork, nomex, kapton, plastic, elastomers, reversible material, and combinations thereof. 20. The apparatus of claim 14 wherein the device is selected from the group consisting of a garment, touchpad, touchscreen, tool, display, keyboard, button, glove, suit, shirt, hat, goggles, spectacles, shoes, pants, socks, undergarments, clothing accessories, necklaces, bracelets, jewelry, and combinations thereof. 21. The apparatus of claim 14 further comprising one or more transponders adaptable to interact with an incident signal thereon to produce a second signal, wherein the second signal is used to track movement of said transponders."

  "description_excerpt": "Embodiments of the present subject matter generally relate to devices, systems, devices and methods for providing haptic technology. Further embodiments of the present subject matter may provide methods, systems and devices for providing a virtual reality system.\n\nVirtual reality systems and associated technologies have witnessed a steady evolution in a wide variety of industries, e.g., air traffic control, architectural design, aircraft design, acoustical evaluation, computer aided design, education (virtual science laboratories), entertainment, legal/police (re-enactment of accidents and crimes), medical applications such as virtual surgery, scientific visualization (aerodynamic simulations, computational fluid dynamics), telepresence, robotics, and flight simulators, to name a few.\n\nUntil recently, one component lacking in conventional virtual reality systems has been the sense of touch or “haptics.” In pre-haptic virtual reality systems, a user could reach out and touch a virtual object but would place his hand through the object thereby reducing the realistic effect of the associated system. Haptic technology, however, provides force feedback in which a user receives the sensation of physical mass in such objects presented in a virtual world by a computer.\n\nGenerally, haptic technology is an interfacing of a system with a user via the sense of touch through the application of forces, vibrations and/or motions to the user.",
