Abstract

A wearable device includes at least one lens, an output device, at least one sensor, and at least one processor. The at least one processor is configured to identify a level of light sensed through the at least one sensor. The at least one processor is also configured to provide a notification related to the level of the light by using the output device when the level of the light satisfies a preset condition.

First claim

What is claimed is:

1. A wearable device comprising:
at least one lens;
a display;
at least one sensor; and
at least one processor, wherein the at least one processor is configured to:
identify a level of light sensed through the at least one sensor; and
control the display to display a notification indicating that the wearable device is in a situation in which the display is capable of being damaged by the light when the level of the light satisfies a preset condition.

2. The wearable device of claim 1 , wherein the at least one processor is further configured to:
identify a type of the light as being one of natural light or artificial light; and
control the display to display the notification by using the display when the type of the light is the natural light.

3. The wearable device of claim 1 , further comprising a plate,
wherein:
the plate comprises a first surface directed toward the display and a second surface opposing the first surface,
the plate further comprises an opening in at least a partial region thereof and the at least one lens is aligned with the opening, and
the at least one sensor is arranged on the second surface of the plate.

4. The wearable device of claim 1 , wherein the at least one processor is further configured to:
identify the level of the light sensed through the at least one sensor when identifying, by using the at least one sensor, that the wearable device is not worn, the level of the light including intensity of the light.

5. The wearable device of claim 1 , further comprising a communication module, wherein the at least one processor is further configured to transmit the notification to an external electronic device through the communication module, when the level of the light satisfies the preset condition.

6. The wearable device of claim 1 , further comprising a speaker,
wherein the at least one processor is further configured to output audio corresponding to the notification through the speaker, when the level of the light satisfies the preset condition.

7. The wearable device of claim 1 , wherein the at least one processor is configured to control the display to display to an image corresponding to the notification, when the level of the light satisfies the preset condition.

8. The wearable device of claim 1 , further comprising:
a plurality of sectors that are arranged adjacent to the at least one lens to adjust a size of an exposure region of the at least one lens; and
a driving circuit configured to control motion of the plurality of sectors,
wherein the at least one processor is configured to control the motion of the plurality of sectors to reduce the exposure region of the at least one lens through the driving circuit, when the level of the light satisfies the preset condition.

9. The wearable device of claim 8 , wherein the at least one processor is further configured to:
identify a type of the light as being one of natural light or artificial light; and
control the motion of the plurality of sectors to reduce the exposure region of the at least one lens through the driving circuit, when the type of the light is the natural light.

10. The wearable device of claim 8 , wherein the at least one processor is further configured to control the motion of the plurality of sectors to increase the exposure region of the at least one lens through the driving circuit, when determining that the wearable device is worn.

11. The wearable device of claim 8 , wherein the at least one processor is further configured to control the display to display a notification related to the level of the light through display when the level of the light satisfies the preset condition.

12. The wearable device of claim 8 , wherein the at least one processor is further configured to control the motion of the plurality of sectors to reduce the exposure region of the at least one lens through the driving circuit, when receiving a display protection mode entry command for protecting the display.

13. A non-transitory storage medium containing instructions that when executed cause at least one processor of a wearable device comprising at least one lens, a display, at least one sensor, and the at least one processor, to:
sense light through the at least one sensor;
identify a level of the sensed light; and
control the display to display a notification indicating that the wearable device is in a situation in which the display is capable of being damaged by the light when the level of the light satisfies a preset condition.

14. The non-transitory storage medium of claim 13 , wherein the instructions when executed further cause the at least one processor to:
identify a type of the light being one of natural light or artificial light; and
control the display to display the notification when the type of the light is the natural light.

15. The non-transitory storage medium of claim 13 , wherein the instructions when executed further cause the at least one processor to:
identify the level of the light sensed through the at least one sensor when identifying that the wearable device is not worn, the level of the light including intensity of the light.

16. The non-transitory storage medium of claim 13 , wherein the instructions when executed further cause the at least one processor to transmit the notification to an external electronic device through a communication module of the wearable device when the level of the light satisfies the preset condition.

17. The non-transitory storage medium of claim 13 , wherein the instructions when executed further cause the at least one processor to output audio corresponding to the notification through the display when the level of the light satisfies the preset condition.

18. The non-transitory storage medium of claim 13 , wherein the instructions when executed further cause the at least one processor to control the display to display an image corresponding to the notification when the level of the light satisfies the preset condition.
