Description

Technical Field

[0001] The present disclosure relates to a wearable device for providing information about an application (eg, a running application) on the wearable device through an external display and a method of controlling the wearable device. Background Art

[0002] More and more services and additional functions are provided through electronic devices (e.g., portable electronic devices, such as wearable devices that provide virtual reality). In order to improve the practicality of electronic devices and meet various user needs, communication service providers or electronic device manufacturers are competing to develop electronic devices for the purpose of providing various functions and distinguishing themselves from other companies.

The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., an application processor (AP)), and support direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate via a first network 198 (e.g., a short-range communication network such as Bluetooth TM , Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (for example, a long-distance communication network such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (for example, a LAN or a wide area network (WAN)))) to communicate with an external electronic device.

Alternatively, when a user input for displaying only summary information of the current screen being displayed on the first display 208 (e.g., the title of the video being displayed) through the second display 240 is obtained from the user, the wearable device 200 may display the summary information of the current screen being displayed on the first display 208 through the second display 240. According to an embodiment of the present disclosure, the user input for determining the display type to be displayed on the second display 240 may be obtained preliminarily (e.g., before displaying the first operation screen) or when displaying the first operation screen. The wearable device 200 may determine the display type of information to be displayed on the second display 240 based on the current location of the user. For example, when it is determined that the user is currently located in a public place (e.g., a department store, a company, etc.), the wearable device 200 may display summary information or no information on the second display 240. When it is determined that the user is located in a private place (e.g., the user's home), the wearable device 200 may display a screen corresponding to the screen being displayed on the first display 208 through the second display 240. The wearable device 200 may determine the current location of the user through at least one sensor included in the wearable device 200 (e.g., an inertial measurement unit (IMU) sensor, a GPG sensor, etc.), and determine whether the current location is a public place or a private place. When the wearable device 200 includes at least one camera having a sensor exposed to the outside (e.g., a complementary metal oxide semiconductor (CMOS) sensor), the wearable device 200 may also determine whether the current location is a public place or a private place based on an image captured by the at least one camera. For example, when a specified number or more of external objects (e.g., nearby people) are in an image captured by at least one camera, the wearable device 200 can determine that the current location is a public place. Alternatively, the wearable device 200 can determine whether the current location is a public place or a private place based on the characteristics of the captured external objects (e.g., the name of a specific company, the internal layout of a building, etc.). For example, the wearable device 200 can determine whether the current location is a public place or a private place by comparing an image pre-stored in the wearable device 200 with the captured image. The wearable device 200 can determine whether the current location is a public place or a private place based on input preliminarily obtained from the user.For example, when the user has designated a specific location (e.g., 129, Samseong-ro, Yeongtong-gu, Suwon-si, Gyeonggi-do) as a public place (e.g., a company) and the wearable device 200 is located at the specific location (e.g., 129, Samseong-ro, Yeongtong-gu, Suwon-si, Gyeonggi-do), the wearable device 200 can determine the current location as a "public place."

For example, the wearable device 200 may display the screen being displayed on the first display 208 as is through the second display 240. Alternatively, the wearable device 200 may display summary information of the current screen being displayed on the first display 208 (e.g., the title of the video being played) through the second display 240.
