Abstract

The wrist rest may include a base structure; at least two flexible supports extending from the base structure; a vibration assembly supported on the at least two flexible supports in a manner such that the vibration assembly may be spaced apart from the base structure; and a cushion assembly including a cushion disposed over the vibration assembly in a manner so as to conceal the vibration assembly between the base structure and the cushion. The cushion may be secured to the base structure. The at least two flexible supports may be configured to isolate the base structure from a vibrating motion of the vibration assembly. A surface of the vibration assembly directed towards the cushion assembly may move relative to a corresponding surface of the cushion assembly in a manner so as to allow the vibration motion of the vibration assembly to be sensed through the cushion.

First claim

The invention claimed is:

1. A wrist rest, comprising:
a base structure;
a cushion assembly comprising a cushion that is secured to the base structure; and
a vibration assembly spaced apart from the base structure,
wherein a vibrating motion of the vibration assembly causes a surface of the vibration assembly to move in a manner so as to allow the vibration motion of the vibration assembly to be sensed through the cushion of the cushion assembly, and
wherein the cushion assembly further comprises a cushion-wrap wrapped over the cushion and fixed to the base structure.

2. The wrist rest as claimed in claim 1 , wherein the vibration assembly comprises at least two actuators, wherein the at least two actuators are suspended from the base structure.

3. The wrist rest as claimed in claim 1 further includes at least two flexible supports extending from the base structure.

4. The wrist rest as claimed in claim 3 , wherein the vibration assembly is spaced apart from the base structure by the at least two flexible supports.

5. The wrist rest as claimed in claim 3 , wherein the at least two flexible supports are configured to isolate the base structure from the vibration motion of the vibration assembly.

6. The wrist rest as claimed in claim 1 , wherein a fluid or gel is filled between the cushion and the vibration assembly.

7. The wrist rest as claimed in claim 1 , wherein the cushion assembly comprises a lubricating plate fixedly attached to the cushion of the cushion assembly directed towards the vibration assembly such that the lubricating plate is in contact with the vibration assembly.

8. The wrist rest as claimed in claim 1 , wherein a surface of the vibration assembly directed towards the cushion assembly comprises bumps or rounded protrusions projecting therefrom, or one or more lubricating pads attached thereon, wherein the one or more lubricating pads are made of self-lubricating material.

9. The wrist rest as claimed in claim 1 , further comprising a sensor configured to detect whether a body is within a pre-determined vicinity region of the wrist rest so as to switch the vibration assembly from a sleep mode to an operational mode upon detection of the body so as to be ready for generating the vibrating motion.

10. The wrist rest as claimed in claim 9 , wherein the sensor is coupled to a power regulating circuit that controls power supply to the vibration assembly.

11. A wrist rest, comprising:
a base structure;
a cushion secured to the base structure; and
a plurality of actuators embedded within the cushion to cause a surface of the wrist rest to vibrate when haptic feedback is required for the wrist rest, and
wherein each of the actuators receives a haptic signal from a host computer to generate the haptic feedback for the wrist rest.

12. The wrist rest as claimed in claim 11 further includes a controller that receives haptic feedback instructions from the host computer and generates the haptic signal corresponding to the haptic feedback instructions.

13. The wrist rest as claimed in claim 11 , wherein the cushion covers the base structure to enclose an internal space of the wrist rest such that the actuators are suspended from the base structure.

14. The wrist rest as claimed in claim 11 further includes a cushion-wrap wrapped over the cushion and fixed to the base structure in a manner so as to bundle the cushion to the base structure.

15. The wrist rest as claimed in claim 11 , wherein the cushion includes cut out portions to embed the actuators.

16. The wrist rest as claimed in claim 11 further includes at least two flexible supports to isolate the base structure from vibration.

17. The wrist rest as claimed in claim 11 , wherein the actuators are spaced apart from one another.

18. The wrist rest as claimed in claim 11 , further comprising a sensor configured to detect whether a body is within a pre-determined vicinity region of the wrist rest so as to switch the actuators from a sleep mode to an operational mode upon detection of the body so as to be ready for generating the haptic feedback.

19. The wrist rest as claimed in claim 18 , wherein the sensor sends a signal to a processor of the host computer upon detection of the body such that the processor sends the haptic signal to the actuators for generating the haptic feedback.

20. The wrist rest as claimed in claim 18 , wherein the sensor sends a signal to a controller of the wrist rest upon detection of the body such that the controller sends the haptic signal to the actuators for generating the haptic feedback.
