Wearable device on which virtual object is displayed by using single display module or plurality of display modules, and control method thereof

A method for controlling a wearable device, the method comprising:

• outputting image data through a first display module of the wearable device and a second display module of the wearable device in a first mode;
• switching from the first mode to a second mode based on at least one of an occurrence of a notification event, a moving speed of the wearable device, or a type of an application executing on the wearable device;
• determining any one of the first display module or the second display module as an output display module in the second mode;
• and
• controlling the output display module to output the image data through the determined output display module,
• wherein in the first mode, the image data is displayed as a three-dimensional virtual object by using the first display module to display the image data to a first eye of a user and the second display module to display the image data to a second eye of the user, and
• wherein in the second mode, the image data is displayed as a two-dimensional virtual object by using any one of the first display module or the second display module to display the image data to a single eye of the user, the second mode configured to conserve power of the wearable device.

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of a wearable device individually or collectively, cause the wearable device to perform operations, the operations comprising:

• outputting image data through a first display module of the wearable device and a second display module of the wearable device in a first mode;
• switching from the first mode to a second mode based on at least one of an occurrence of a notification event, a moving speed of the wearable device, or a type of an application executing on the wearable device;
• determining any one of the first display module or the second display module as an output display module in the second mode;
• and
• controlling the output display module to output the image data through the determined output display module,
• wherein in the first mode, the image data is displayed as a three-dimensional virtual object by using the first display module to display the image data to a first eye of a user and the second display module to display the image data to a second eye of the user, and
• wherein in the second mode, the image data is displayed as a two-dimensional virtual object by using any one of the first display module or the second display module to display the image data to a single eye of the user, the second mode configured to conserve power of the wearable device.
