Abstract

A wireless headset capable of wireless communication with an external device is provided. The wireless headset includes a status indication unit, which emits one of at least three colors of light, and a control unit which controls the status indication unit. The control unit determines whether the wireless headset is connected to an external power source and controls to light a first color when the wireless headset is connected and a residual battery charge of the wireless headset is at a low level, to light a third color when the wireless headset is connected and the residual battery charge is at a high level, and to blink the first color when the wireless headset is not connected to the external power and the residual battery charge is at the low level.

Claims

a status indication unit which emits one of at least three colors of light; and

a control unit which controls the status indication unit,

wherein the control unit determines whether the wireless headset is connected to an external power source and controls to light a first color when the wireless headset is connected and residual battery charge of the wireless headset is at a low level and to light a third color when the wireless headset is connected and the residual battery charge is at a high level and to blink the first color when the wireless headset is not connected to the external power and the residual battery charge is at the low level.

2. The wireless headset of claim 1, wherein the control unit controls to light a second color when the wireless headset is connected to the external power and the residual battery charge is at an intermediate level.

3. The wireless headset of claim 2, wherein the status indication unit comprises a first Light Emitting Display (LED) and a second LED, wherein the control unit controls the first LED to emit the first color, the second LED to emit the third color, and both the first and second LEDs to emit the second color.

4. The wireless headset of claim 1, wherein the control unit controls, in a state where the wireless headset is disconnected from the external power source, to blink the third color when the residual battery charge is at the high level, the second color when the residual battery charge is at an intermediate level, and the first color when the residual battery charge is at the low level.

5. A battery status indication method of a wireless headset, the method comprising:

determining whether the wireless headset is connected to an external power source;

checking residual battery charge of the wireless headset;

lighting a first color when the wireless headset is connected and residual battery charge of the wireless headset is at a low level;

lighting a third color when the wireless headset is connected and the residual battery charge is at a high level; and

blinking the first color when the wireless headset is not connected to the external power and the residual battery charge is at the low level.

6. The method of claim 5, further comprising lighting a second color when the wireless headset is connected to the external power and the residual battery charge is at an intermediate level.

7. The method of claim 5, wherein blinking comprises:

blinking the third color when the wireless headset is disconnected from the external headset and the residual battery charge is at the high level; and

blinking a second color when the wireless headset is disconnected from the external headset and the residual battery charge is at an intermediate level

8. A battery status indication method of a portable electronic device, the method comprising:

determining whether the portable electronic device is connected to an external power source;

checking residual battery charge of the portable electronic device;

lighting a first color when the portable electronic device is connected and residual battery charge of the portable electronic device is at a low level;

lighting a third color when the portable electronic device is connected and the residual battery charge is at a high level; and

blinking the first color when the portable electronic device is not connected to the external power and the residual battery charge is at the low level.

9. The method of claim 8, further comprising lighting a second color when the portable electronic device is connected to the external power and the residual battery charge is at an intermediate level.

10. A portable electronic device, the device comprising:

a status indication unit which emits one of at least three colors of light; and

a control unit which controls the status indication unit,

wherein the control unit determines whether the portable electronic device is connected to an external power source and controls to light a first color when the portable electronic device is connected and residual battery charge of the portable electronic device is at a low level and to light a third color when the portable electronic device is connected and the residual battery charge is at a high level and to blink the first color when the portable electronic device is not connected to the external power and the residual battery charge is at the low level.

11. The device of claim 10, wherein the control unit controls to light a second color when the portable electronic device is connected to the external power and the residual battery charge is at an intermediate level.

12. A wireless headset capable of wireless communication with an external device, the wireless headset comprising:

a status indication unit which emits at least one of three colors of light; and

a control unit which controls the status indication unit,

wherein the control unit determines whether the wireless headset is connected to an external power source and controls to blink a first color when the wireless headset is connected and residual battery charge of the wireless headset is at a low level and to blink a third color when the wireless headset is connected and the residual battery charge is at a high level and to light the first color when the wireless headset is not connected to the external power and the residual battery charge is at the low level.

13. The wireless headset of claim 12, wherein the control unit controls to blink a second color when the wireless headset is connected to the external power and the residual battery charge is at an intermediate level.

14. A battery status indication method of a wireless headset, the method comprising:

determining whether the wireless headset is connected to an external power source;

checking residual battery charge of the wireless headset;

blinking a first color when the wireless headset is connected and residual battery charge of the wireless headset is at a low level;

blinking a third color when the wireless headset is connected and the residual battery charge is at a high level; and

lighting the first color when the wireless headset is not connected to the external power and the residual battery charge is at the low level.

15. The method of claim 14, further comprising blinking a second color when the wireless headset is connected to the external power and the residual battery charge is at an intermediate level.

16. A battery status indication method of a portable electronic device, the method comprising:

determining whether the portable electronic device is connected to an external power source;

checking residual battery charge of the portable electronic device;

blinking a first color when the portable electronic device is connected and residual battery charge of the portable electronic device is at a low level;

blinking a third color when the portable electronic device is connected and the residual battery charge is at a high level; and
