Abstract

A method of controlling a head mounted display (HMD) according to one embodiment of the present specification includes performing a first operation, receiving a first voice input through an audio input unit, processing the first voice input with respect to the first operation while a first contact is detected through a first sensor positioned at a nose pad of the HMD, detecting the first contact being released through the first sensor positioned at a nose pad of the HMD, receiving a second voice input through the audio input unit while the first contact is released, and performing a second operation according to the received second voice input.

Claims

1. A head mounted display (HMD), comprising:

a display unit configured to display digital information;

an audio input unit configured to receive a voice input;

a first sensor configured to detect a first contact, wherein the first sensor is positioned at a nose pad of the HMD and detects the first contact when the nose pad of the HMD contacts a first designated area of a user'"'"'s head; and

a controller configured to;

perform a first operation;

receive, through the audio input unit, a first voice input while the first contact is detected,

process the first voice input with respect to the first operation,

detect, through the first sensor, the first contact being released,

receive, through the audio input unit, a second voice input while the first contact is released,

perform a second operation according to the received second voice input,

detect the first contact again after being released,

receive, through the audio input unit, a third voice input while the first contact is detected, and

process the third voice input with respect to the first operation,

wherein processing the third voice input is sequential to processing the first voice input with respect to the first operation.

2. The HMD of claim 1, further comprising a second sensor configured to detect a second contact, wherein the second sensor is positioned at a temple of the HMD, and detects the second contact when the temple of the HMD contacts a second designated area of the user'"'"'s head.

3. The HMD of claim 1, further comprising a communication unit configured to perform telecommunication by transmitting the received voice input, wherein the first operation is the telecommunication.

4. The HMD of claim 3, wherein the controller excludes the second voice input from transmission.

5. A head mounted display (HMD), comprising:

a display unit configured to display digital information;

an audio input unit configured to receive a voice input;

a first sensor configured to detect a first contact, wherein the first sensor is positioned at a nose pad of the HMD; and

a controller configured to;

detect an event while a first voice input is being received through the audio input unit and the first contact is detected, wherein the first voice input is related with a first voice command,

detect, through the first sensor, the first contact being released,

receive, through the audio input unit, a second voice input with respect to the event while the first contact is released, and

perform a second voice command according to the received second voice input,

wherein the second voice command is independent of the first voice command and the second voice command is related to the detected event.

6. The HMD of claim 5, the controller further configured to:

detect the first contact again after being released,

receive, through the audio input unit, a third voice input while the first contact is detected, and

perform the first voice command according to the first voice input and the third voice input.

7. The HMD of claim 5, wherein the second command is not related to the first command.

8. The HMD of claim 5, wherein the event includes an e-mail receiving event, a message receiving event or schedule notifying event.

9. The HMD of claim 5, wherein the controller further configured to display the second voice input on the display unit.

10. A method of controlling a head mounted display (HMD), the method comprising:

performing a first operation;

receiving, through an audio input unit, a first voice input;

processing the first voice input with respect to the first operation while a first contact is detected through a first sensor positioned at a nose pad of the HMD, wherein the first contact is detected when the nose pad of the HMD contacts a first designated area of a user'"'"'s head;

detecting, through the first sensor positioned at the nose pad of the HMD, the first contact being release when the nose pad of the HMD is released from the first designated area of the user'"'"'s head;

receiving, through the audio input unit, a second voice input while the first contact is released;

performing a second operation according to the received second voice input;

detecting the first contact again after being released;

receiving, through the audio input unit, a third voice input while the first contact is detected; and

processing the third voice input with respect to the first operation,

wherein processing the third voice input is sequential to processing the first voice input with respect to the first operation.

11. The method of claim 10, further comprising:

detecting, by a second sensor of the HMD, a second contact when a temple of the HMD contacts a second designated area of the user'"'"'s head.

12. The method of claim 10, wherein the first operation is the telecommunication.

13. The method of claim 12, wherein the second voice input is excluded from transmission.

14. A method of controlling a head mounted display (HMD), the method comprising:

detecting an event while a first voice input is being received through an audio input unit and a first contact is detected through a first sensor positioned at a nose pad of the HMD, wherein the first voice input is related with a first voice command;

detecting, through the first sensor, the first contact being released;

receiving, through the audio input unit, a second voice input with respect to the event while the first contact is released; and

performing a second voice command according to the received second voice input,

wherein the second voice command is independent of the first voice command and the second voice command is related to the detected event.

15. The method of claim 14, further comprising:

detecting the first contact again after being release;

receiving, through the audio input unit, a third voice input while the first contact is detected; and

performing the first voice command according to the first voice input and the third voice input.

16. The method of claim 14, wherein the second command is not related to the first command.

17. The method of claim 14, wherein the event includes an e-mail receiving event, a message receiving event or schedule notifying event.

18. The method of claim 14, wherein the second voice input is displayed on the display unit.
