Abstract

According to various embodiments, a wrist rest is provided. The wrist rest comprises a base structure, a plurality of light sources housed in the base structure and capable of emitting light, a light guide disposed over the plurality of light sources and configured to receive the light emitted from the plurality of light sources and release the light, and a cushion secured to the base structure and disposed over the light guide in a manner so as to conceal the plurality of light sources and the light guide between the base structure and the cushion. The cushion is configured to diffuse the light released from the light guide. Each light source is capable of selectively producing a plurality of lighting colours.

First claim

The invention claimed is:

1 . A wrist rest comprising:
a base structure; a plurality of light sources housed in the base structure and capable of emitting light; a light guide disposed over the plurality of light sources, and configured to receive the light emitted from the plurality of light sources and release the light, wherein each light source is capable of selectively producing a plurality of lighting colours, wherein the plurality of light sources includes a plurality of RGB LEDs (red-green-blue light emitting diodes); a cushion secured to the base structure and disposed over the light guide in a manner so as to conceal the plurality of light sources and the light guide between the base structure and the cushion, wherein the cushion is configured to diffuse the light released from the light guide; a circuit board housed in the base structure, wherein the RGB LEDs are mounted on the circuit board; and a battery housed in the base structure and operable to supply power to the plurality of light sources, wherein the circuit board comprises a cut-out, and the battery is configured to be inserted into the cut-out to connect the battery to the circuit board.

2 . The wrist rest according to claim 1 , wherein the cushion is formed of translucent soft gel.

3 . The wrist rest according to claim 1 , further comprising a controller operable to control each light source to produce at least one predetermined lighting colour among the plurality of lighting colours based on a predetermined lighting profile.

4 . The wrist rest according to claim 3 , further comprising a communication module operable to receive a wireless signal comprising information about the lighting profile and provide the information to the controller,
further comprising a communication device configured to be detachably couplable to an external electronic device, and operable to communicatively connect the communication module with the electronic device through a network, wherein the base structure further comprises a slot disposed at a bottom side of the base structure to house the communication device, wherein the base structure further comprises a detachable door flap configured to cover the slot.

5 . The wrist rest according to claim 1 , further comprising a port disposed on a side wall of the base structure and configured to allow a power cable to be plugged therein to receive power from an external power source.

6 . The wrist rest according to claim 1 , further comprising at least one switch operable to receive an input from a user to control the plurality of light sources.

7 . The wrist rest according to claim 6 , wherein the switch includes a first switch operable to power on and off the plurality of light sources, preferably wherein the switch includes a second switch operable to trigger switching between a plurality of lighting
profiles to control each light source to produce at least one predetermined lighting colour respectively based on one of the plurality of lighting profiles selected by the switching.

8 . A system, comprising:
a wrist rest comprising: a base structure; a plurality of light sources housed in the base structure and capable of emitting light, wherein each light source is capable of selectively producing a plurality of lighting colours, wherein the plurality of light sources includes a plurality of RGB LEDs (red-green-blue light emitting diodes); a light guide disposed over the plurality of light sources, and configured to receive the light emitted from the plurality of light sources and release the light; and a cushion secured to the base structure and disposed over the light guide in a manner so as to conceal the plurality of light sources and the light guide between the base structure and the cushion, wherein the cushion is configured to diffuse the light released from the light guide; and an electronic device capable of communicating with the wrist rest and operable to transmit a wireless signal comprising information about a lighting profile to the wrist rest; a circuit board housed in the base structure, wherein the RGB LEDs are mounted on the circuit board; and a battery housed in the base structure and operable to supply power to the plurality of light sources, wherein the circuit board comprises a cut-out, and the battery is configured to be inserted into the cut-out to connect the battery to the circuit board.

9 . The system according to claim 8 , wherein the cushion is formed of translucent soft gel.

10 . The system according to claim 8 , wherein the wrist rest further comprises a controller operable to control each light source to produce at least one predetermined lighting colour among the plurality of lighting colours based on the lighting profile according to the signal received from the electronic device.

11 . The system according to claim 10 , wherein the wrist rest further comprises a communication module operable to receive the signal comprising the information about the lighting profile and provide the information to the controller,
wherein the wrist rest further comprises a communication device configured to be detachably couplable to the electronic device, and operable to communicatively connect the communication module with the electronic device through a network, wherein the base structure further comprises a slot disposed at a bottom side of the base structure to house the communication device, wherein the base structure further comprises a detachable door flap configured to cover the slot.

12 . The system according to claim 8 , wherein the wrist rest further comprises a port disposed on a side wall of the base structure and configured to allow a power cable to be plugged therein to receive power from an external power source or the electronic device.

13 . The system according to claim 8 , wherein the wrist rest further comprises at least one switch operable to receive an input from a user to control the plurality of light sources.

14 . The system according to claim 13 , wherein the switch includes a first switch operable to power on and off the plurality of light sources.

15 . The system according to claim 13 , wherein the switch includes a second switch operable to trigger switching between a plurality of lighting profiles to control each light source to produce at least one predetermined lighting colour respectively based on one of the plurality of lighting profiles selected by the switching.

16 . The system according to claim 15 , wherein when the second switch is triggered to switch to a different lighting profile, the wrist rest is operable to transmit a switching signal to the electronic device, and the electronic device is operable to transmit a signal comprising information about said lighting profile to the wrist rest, and/or wherein the wrist rest further comprises a memory, and when the second switch is triggered to switch to a different lighting profile, a controller is operable to control each light source to produce at least one predetermined lighting colour respectively based on information about said lighting profile saved in the memory.

17 . The system according to claim 8 , wherein the electronic device is operable to update the lighting profile and provide the wrist rest with information about the updated lighting profile.

18 . The system according to claim 8 , wherein the electronic device includes at least one of the following: a mobile phone, a tablet computer, a laptop computer, a desktop computer, a head-mounted display and a smart watch.
