Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Application No. PCT/KR2021/016232 designating the United States, filed on Nov. 9, 2021, in the Korean Intellectual Property Receiving Office and claiming priority to Korean Patent Application No. 10-2020-0148711 filed on Nov. 9, 2020, the disclosures of which are incorporated by reference herein in their entireties.

BACKGROUNDField

Various embodiments of the present disclosure relate to an electronic device and/or method for offering a virtual reality object.

Description of Related Art

Research and development for an augmented reality (AR) function and its use are increasing. Augmented reality can be a technology for synthesizing virtual related information (e.g., a text, an image, etc.) to a real thing (e.g., a real environment) and showing. Augmented reality can, unlike virtual reality (VR) aiming at only a virtual space and thing, provide a virtual object on an object called a real environment. Virtual reality can be a virtual space which is implemented to have a similar experience with reality with respect to the virtual space and a virtual thing. Mixed reality (MR) can mean a space which is made by combining and merging virtual information and reality information.

To provide virtual and/or augmented reality contents, a camera of an electronic device can acquire a rendering image continuously tracking a user who is a subject which is a photographing target and reflecting a location, look or/and direction, etc. of the user. In this case, because the camera included in the electronic device has a restricted angle range of view (e.g., general angle (standard angle), wide angle or narrow angle (e.g., telescope angle)), there is a limit in tracking a location, look and/or direction, etc. of the user, when the user moves.

SUMMARY

Various example embodiments can offer a technique/method for setting various events capable of occurring when a virtual realty service is used by using an electronic device and a wearable device, and offering virtual and/or augmented reality contents wherein the virtual reality service can be seamlessly smoothly used by using peripheral space information of a user, and an electronic device supporting the same.

In accordance with various example embodiments of the present disclosure, an electronic device can include a communication module comprising communication circuitry, a camera, and at least one processor (comprising processing circuitry) operably coupled with the communication module and the camera. The at least one processor can be configured to establish a communication connection with an external device and a wearable device using the communication module, and acquire an image through the camera, and acquire first object information for rendering a first virtual reality object based on the image, and transmit the first object information to the external device through the communication module, and while transmitting the first object information to the external device, determine whether a specified event occurs, and acquire map information on a peripheral environment of the electronic device based on at least one of first peripheral space information including information on an object located within a first region, acquired using the camera, or second peripheral space information including information on an object located within a second region, received from the wearable device, and based on the occurrence of the specified event, transmit second object information which includes the map information and information on a location of the first virtual reality object within the map information, to the external device.

An operation method of an electronic device of various example embodiments can include establishing a communication connection with an external device and a wearable device using a communication module comprising communication circuitry, and acquiring an image through a camera, and acquiring first object information for rendering a first virtual reality object based on the image, and transmitting the first object information to the external device through the communication module, and while transmitting the first object information to the external device, determining whether a specified event occurs, and acquiring map information on a peripheral environment of the electronic device based on at least one of first peripheral space information including information on an object located within a first region, acquired using the camera, or second peripheral space information including information on an object located within a second region, received from the wearable device, and based on the occurrence of the specified event, transmitting second object information which includes the map information and information on a location of the first virtual reality object within the map information, to the external device.

According to an example embodiment, although a user who takes part in a call using an augmented reality service or a virtual realty service gets out of a range of view angle of a camera included in an electronic device, the electronic device can offer virtual or/and augmented reality contents in order to smoothly proceed with the call which uses the augmented realty service or virtual reality service, and increase an activity scope of the user.

Also, according to an example embodiment, a rendering image representative of the user and/or a rendering image including information on the user and a peripheral space around the user can be offered as virtual and/or augmented reality contents according to context related to the call which uses the augmented reality service or virtual reality service.

Besides this, various effects taken directly or indirectly through the present document can be offered.

The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a 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 may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 (comprising communication circuitry) may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology.

In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

According to various example embodiments, the antenna module 197 may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108.

According to an embodiment, the electronic device 100 (e.g., the processor 120 of FIG. 3) can, in operation 501, connect communication with the external device 104 and/or the wearable device 102 using the communication module 190.

According to an embodiment, the electronic device 100 (e.g., the processor 120 of FIG. 3) can, in operation 503, acquire an image using the camera 181.

According to an embodiment, the electronic device 100 (e.g., the processor 120) can, in operation 505, acquire first object information which includes information for rendering the first virtual reality object 900a, based on the image acquired through the camera 181.

According to an embodiment, the electronic device 100 (e.g., the processor 120 of FIG. 3) can, in operation 507, transmit the first object information to the external device 104.

According to an embodiment, the electronic device 100 (e.g., the processor 120 of FIG. 3) can, in operation 509, determine whether a specified event has occurred while the first object information is transmitted to the external device 104. For example, in response to an object corresponding to the first object information not being obtained within the image acquired through the camera 181, the electronic device 100 can determine that the specified event has occurred.

In an embodiment, a description of the specified event is made in detail with reference to FIG. 8.

According to an embodiment, in response to the specified event not having occurred, the electronic device 100 (e.g., the processor 120 of FIG. 3) can, in operation 511, transmit the first object information to the external device 104.

According to an embodiment, in response to the specified event occurring, the electronic device 100 (e.g., the processor 120 of FIG. 3) can, in operation 513, acquire the map information on a peripheral environment of the electronic device 100 based on at least one of the first peripheral space information acquired through the camera 181 or the second peripheral space information acquired through the wearable device 102.

In an example, the electronic device 100 can acquire the first peripheral space information using information on an object located in a third region, acquired through the rear camera 180b.

For example, the electronic device 100 can determine that the specified event has occurred, because the object corresponding to the first object information is not obtained within the image acquired through the camera 181. In this case, because the first user 800 escapes a range of view angle of the camera 181, the electronic device 100 cannot acquire an image which includes an object corresponding to the first user 800 and information tracking a portion of a body of the first user 800, using the camera 181. The electronic device 100 can transmit the second object information which includes the map information and the information on the location of the first virtual reality object 900a within the map information, to the external deice 104.
