Abstract

A method for providing tactile feedback comprises displaying a visual representation of a physical object having at least one haptic property, generating time-varying data associated with the at least one haptic property from the visual representation, sending the time-varying data to a computing device including a feedback apparatus electrically connected to the computing device, and generating the tactile feedback via the feedback apparatus in response to a pressure on the feedback apparatus applied by a user.

Claims

1. A method for providing tactile feedback, comprising:

capturing a visual representation of a physical object having at least one haptic property;

segmenting the captured visual representation into a plurality of portions;

generating, at a first computing device, time-varying data associated with at least one haptic property of each of the portions;

sending, via a network and from the first computing device, the visual representation and the time-varying data to a second computing device including a feedback apparatus electrically connected to the second computing device, wherein the time-varying data is sent to the second computing device as meta data; and

generating the tactile feedback via the feedback apparatus in response to a pressure on the feedback apparatus applied by a user;

wherein a haptic property of a first portion of the plurality of portions comprises a first texture and a haptic property of a second portion of the plurality of portions comprises a second texture that is different from the first texture;

wherein the time-varying data is processed such that the feedback apparatus of the second computing device is configured to present at least the haptic properties of each of the first and second portions of the captured visual representation; and

wherein the time-varying data varies based at least on differences between the haptic properties of each of the first and second portions.

2. The method of claim 1, wherein a pattern of the tactile feedback is a time-varying function of the time-varying data.

3. The method of claim 1, wherein the feedback apparatus comprises:

an actuator, wherein the actuator is capable of generating a vibration pattern based on the time-varying data;

a plurality of fibers on the actuator; and

a membrane on the plurality of fibers.

4. The method of claim 3, wherein the actuator induces an electric charge on the fibers, and the fibers move based on the induced electric charge.

5. The method of claim 4, wherein the membrane is magnetic, the electric charge one of repels and attracts the membrane, and the membrane changes shape based on the electric charge.

6. The method of claim 3, wherein the actuator controls at least one of stiffness and temperature of the fibers.

7. The method of claim 3, wherein the tactile feedback includes a two-dimensional time-varying pattern of vibration generated by the actuator.

8. The method of claim 3, wherein the plurality of fibers extend vertically from a surface and are arranged on the surface in a side-by-side configuration.

9. The method of claim 8, wherein, when generating the tactile feedback, a first portion of the plurality of fibers is at a first height with respect to the surface and a second portion of the plurality of fibers is at a second height with respect to the surface different from the first height, the first and second heights being controlled by the actuator.

10. The method of claim 8, wherein the plurality of fibers are configured to move in up, down, left and right directions with respect to the surface from which the plurality of fibers extend.

11. The method of claim 8, wherein, when generating the tactile feedback, a first portion of the plurality of fibers is at a first temperature and a second portion of the plurality of fibers is at a second temperature different from the first temperature, the first and second temperatures being controlled by the actuator.

12. The method of claim 1, wherein the feedback apparatus is integrated into a body of the computing device.

13. The method of claim 1, wherein the feedback apparatus is selectively attached to the computing device via a port.

14. The method of claim 1, wherein communication between the first computing device and the second computing device is performed via multimedia messaging.

15. The method of claim 1, wherein generating the time-varying data comprises mapping a frequency pattern corresponding to each of the segmented portions based on at least the haptic properties of each of the first and second portions.
