Abstract

The present disclosure discloses a wearable device and a method of outputting content thereof. According to one embodiment, the wearable device for outputting the content according to the present invention includes a sensor, a display, and a processor configured to: determine an output mode of the wearable device based on tracking information detected by the sensor, and cause the display to display content in a playback window of a screen, wherein: the playback window corresponds to an entire portion of the display when the output mode is an active mode, and the playback window corresponds to a portion of the display when the output mode is an inactive mode, wherein the portion of the display is less than the entire portion of the display.

First claim

What is claimed is:

1. A method of outputting content by a head-mounted glasses-type wearable device, the method comprising:
determining an output mode of the wearable device based on detected tracking information;
determining an amount of incident light on the wearable device;
determining location information of a source of the incident light based on an angle of reflection of the incident light; and
displaying the content on a screen of the wearable device according to the determined output mode, amount of incident light and location information,
wherein the content is displayed on an entire portion of the screen when the output mode is an active mode, and
wherein the content is displayed on less than the entire portion of the screen when the output mode is an inactive mode.

2. The method of claim 1 , wherein the content corresponds to at least user interface data, video data, image data, text data, map data, application data, or message data.

3. The method of claim 1 , wherein the tracking information is detected by at least a proximity sensor, a camera sensor, an audio sensor, an eye tracking sensor, a motion sensor, or an illumination sensor.

4. The method of claim 1 , further comprising:
assigning a value corresponding to data detected by each of one or more sensors; and
changing a size or a style of the screen based on a comparison of each assigned value to a corresponding threshold value for each of the detected data.

5. The method of claim 1 , further comprising outputting at least an audio alert or a message based on at least the determined amount of incident light or the determined location information.

6. The method of claim 5 , further comprising changing a configuration of the screen or a color of the displayed content based on at least the determined amount of incident light or the determined location information.

7. The method of claim 1 , further comprising:
changing a focal distance of the screen such that it is closer to a user in response to a user gesture detected in a first direction; and
changing the focal distance such that it is farther from the user in response to a user gesture detected in a second direction.

8. The method of claim 1 , further comprising changing a focal distance of the screen based on eye tracking information of a user.

9. A wearable head-mounted glasses-type device, comprising:
at least one sensor configured to detect information;
a display configured to display information; and
a processor configured to:
determine an output mode of the wearable device based on tracking information detected by the at least one sensor;
determine an amount of incident light on the wearable device; and
determine location information of a source of the incident light based on an angle of reflection of the incident light; and
control the display to display content on a screen according to the determined output mode, amount of incident light and location information,
wherein the content is displayed on an entire portion of the screen when the output mode is an active mode, and
wherein the content is displayed on less than the entire portion of the screen when the output mode is an inactive mode.

10. The wearable device of claim 9 , wherein the content corresponds to at least user interface data, video data, image data, text data, map data, application data, or message data.

11. The wearable device of claim 9 , wherein
the tracking information is detected by at least a proximity sensor, a camera sensor, an audio sensor, an eye tracking sensor, a motion sensor, or an illumination sensor.

12. The wearable device of claim 9 , wherein the processor is further configured to:
assign a value corresponding to the data detected by each of one or more of the at least one sensor; and
control the display to change a size or a style of the screen based on a comparison of each assigned value to a corresponding threshold value for each of the detected data.

13. The wearable device of claim 9 , further comprising an audio device, wherein the processor is further configured control the audio device to output an audio alert or control the display to display a message based on at least the determined amount of incident light or the determined location information.

14. The wearable device of claim 13 , wherein the processor is further configured to control the display to change a configuration of the screen or a color of the displayed content based on at least the determined amount of incident light or the determined location information.

15. The wearable device of claim 9 , wherein the processor is configured to:
change a focal distance of the screen such that it is closer to a user in response to a user gesture detected in a first direction; and
change the focal distance such that it is farther from the user in response to a user gesture detected in a second direction.

16. The wearable device of claim 9 , wherein the processor is further configured to change a focal distance of the screen based on eye tracking information of a user.
