Abstract

The invention provides an eyewear device for transmitting a signal and a communication method thereof. The eyewear device comprises a receiving unit, a shutter and a transmitting unit. For example, the receiving unit is capable of receiving a synchronization signal, and the shutter performs an operation in response to the synchronization signal. Meanwhile, the transmitting unit transmits the synchronization signal to another eyewear device. By this way, each eyewear device is capable of receiving the synchronization signal, and re-transmits the synchronization signal to another eyewear device.

Claims

1. An eyewear device for transmitting a signal, comprising:

a receiving unit for receiving an external signal;

a shutter electrically connected to the receiving unit for performing an operation in response to the external signal; and

a transmitting unit electrically connected to the receiving unit for transmitting the external signal to another eyewear device.

2. The eyewear device of claim 1, wherein the external signal comprises a synchronization signal.

3. The eyewear device of claim 1, wherein the operation comprises opening the shutter or shutting the shutter.

4. The eyewear device of claim 1, wherein the external signal comprises a multimedia signal.

5. The eyewear device of claim 4, further comprising:

a playing unit electrically connected to the receiving unit for playing the multimedia signal.

6. The eyewear device of claim 5, wherein the multimedia signal comprises a caption data, an audio data, a video data, or a combination thereof.

7. The eyewear device of claim 5, wherein the playing unit is a speaker.

8. The eyewear device of claim 5, wherein the playing unit is a liquid crystal display.

9. The eyewear device of claim 1, wherein the transmitting unit transmits the external signal to another eyewear device according to a Zigbee protocol, a Bluetooth protocol, or an ANT protocol.

10. A communication method for transmitting a signal with an eyewear device, the eyewear device having a receiving unit, a shutter, and a transmitting unit, the communication method comprising the steps of:

(a) receiving an external signal by the receiving unit;

(b) performing an operation by the shutter in response to the external signal; and

(c) transmitting the external signal to another eyewear device by the transmitting unit.

11. The communication method of claim 10, wherein the external signal comprises a synchronization signal.

12. The communication method of claim 11, wherein the step (b) further comprises opening or shutting the shutter in response to the synchronization signal.

13. A communication method for transmitting a signal between a plurality of eyewear devices, the eyewear devices each having a receiving unit, a shutter, and a transmitting unit, the communication method comprising the steps of:

receiving an external signal by the receiving unit of the first eyewear device;

performing an operation by the shutter of the first eyewear device in response to the external signal;

transmitting the external signal to the second eyewear device by the transmitting unit of the first eyewear device;

receiving the external signal by the receiving unit of the second eyewear device;

performing an operation by the shutter of the second eyewear device in response to the external signal; and

transmitting the external signal to the third eyewear device by the transmitting unit of the second eyewear device.

14. The communication method of claim 13, wherein the external signal comprises a synchronization signal whereby operation of the shutters of the first eyewear device and the second eyewear device is synchronous.
