The speaker (318) is described as being configured at a location adjacent to the ventilation hole (333) in FIGS. 3A to 3C , but is not limited thereto and may be configured at other locations depending on the implementation of the wearable electronic device (200).

[0082] FIG. 4 is a diagram showing the configuration of an external electronic device according to one embodiment.

[0083] An electronic device (e.g., an electronic device (101) of FIG. 1, a wearable electronic device (200) of FIG. 2, and / or a wearable electronic device (300) of FIGS. 3A and 3C) providing a virtual reality space according to one embodiment may be connected to at least one controller (401, 403) that transmits and receives control signals and information according to function execution through a designated communication method (e.g., BLE communication).

[0084] Referring to FIG. 4, according to one embodiment, at least one controller (401, 403) may be an input interface (e.g., an external electronic device) including a haptic motor (e.g., a vibration motor), such as a pointing device or an input control device, and may transmit user interaction in relation to a virtual object displayed in a virtual reality space to the electronic device. Without being limited thereto, the input interface for transmitting user interaction to the electronic device may be replaced with at least one of a keyboard, a mouse, an electronic pen, a smart phone, or an artificial intelligence (AI) device.

[0086] FIG. 5 is a diagram showing a configuration of an electronic device according to one embodiment, FIGS. 6a to 6d are diagrams showing examples of receiving user interaction by an external device or hand gesture in an electronic device according to one embodiment, FIGS. 7a to 7c are diagrams showing examples of user interaction types according to one embodiment, and FIGS. 8a and 8b are diagrams showing examples for outputting a virtual vibration sound in an electronic device according to one embodiment.

[0087] Referring to FIGS. 5, 6A to 6D, 7A to 7C, 8A, and 8B, an electronic device (501) according to an embodiment (e.g., the electronic device (101) of FIG. 1, the wearable electronic device (200) of FIG. 2, and the wearable electronic device (300) of FIGS. 3A to 3C) may be worn by a user. For example, the electronic device (200) may be implemented as either an augmented reality glass (AR glass) or a video see-through (VST) device. The electronic device (501) according to an embodiment may include a processor (510), a display (520), a camera (530), a communication circuit (540), a speaker (550), and a memory (560). However, the electronic device (501) may further include at least one sensor and other components necessary to perform at least one operation. According to one embodiment, the electronic device (501) may be implemented identically or similarly to the electronic device (101) of FIG. 1, the electronic device (200) of FIG. 2, or the electronic device (300) of FIG. 3.

[0088] A processor (510) of an electronic device (501) according to one embodiment (e.g., processor (120) of FIG. 1) may be electrically and / or operatively connected to each other by electronic components such as a display (520), a camera (530), a communication circuit (540), a speaker (550), and a memory (560) and a communication bus (not shown).

[0089] According to one embodiment, the processor (510) may display a virtual object on a virtual reality space (610) through a display (520) (e.g., display (321) of FIG. 3B) while the user is wearing the electronic device (501). According to one embodiment, the electronic device (200) may perform at least one of execution (or activation), display position movement, selection, removal (or deactivation), or other operations on a virtual object displayed on the virtual reality space (610) by at least one input interface through interaction (e.g., interaction) between at least one input interface.

[0090] According to one embodiment, the processor (510) can control the communication circuit (540) to connect with at least one user interface using a short-range communication technology (e.g., Bluetooth low energy (BLE) or WiFi) or wired communication), and can receive a user interaction by the at least one input interface. Here, the at least one input interface can be at least one external electronic device including a haptic motor (e.g., the first controller (401) or the second controller (403) of FIGS. 4 and 6A), a part of the user's body (e.g., the hand (601) of FIG. 6C), or at least one external electronic device that does not include a haptic motor (e.g., the keyboard (603) of FIG. 6C and / or the electronic pen (605) of FIG. 6D). According to one embodiment, the processor (510) can receive a user interaction from at least one external electronic device including a haptic motor or at least one external electronic device that does not include a haptic motor through the communication circuit (540). According to one embodiment, the processor (510) can detect a gesture by a hand (601) or an external electronic device (e.g., the first controller (401) or the second controller (403) of FIGS. 4 and 6A) through a camera (530) or at least one sensor (e.g., a motion sensor), and identify (e.g., receive or acquire) a user interaction corresponding to the detected gesture. According to one embodiment, the processor (510) can check whether a vibration mode is set. The electronic device (501) can display a setting screen for setting a vibration mode in a virtual reality space, and can set at least one of sound, vibration (e.g., system vibration), silent mode, or system mode, and can adjust the vibration intensity and set a specific function for each item (e.g., vibration, alarm, system, or media). For example, the sound mode can be a mode in which an audio source is played from the speaker (550) of the electronic device (501).The electronic device (501) does not have a haptic motor and does not generate physical vibrations, so when an object is operated in a virtual environment, it can generate physical haptic vibrations to an external electronic device. For example, the vibration mode may be a mode in which no audio source is played from the speaker (550), and when an object is operated in a virtual environment, it can generate physical haptic vibrations to the external electronic device. For example, the silent mode may be a mode in which no audio source is played from the speaker (550), and when an object is operated in a virtual environment, physical haptic vibrations may or may not be generated from the external electronic device according to a user setting. According to one embodiment, the electronic device may provide a system mode. For example, a touch feedback interaction operation may be generated from a haptic motor (e.g., a haptic controller haptic actuator) of the external electronic device. A dial keypad interaction operation may be generated from a haptic motor (e.g., a haptic controller haptic actuator) of the external electronic device. For example, a keyboard vibration feedback interaction action may be generated from a controller haptic actuator (motor). For example, a gesture feedback interaction action may be generated from a controller haptic actuator (motor) (e.g., grip, pich, click, zoom in / out, etc.). According to one embodiment, the electronic device (501) may provide a personalized vibration method according to, for example, a vibration setting condition, and for example, the external electronic device may not provide a vibration mode in a low power mode (e.g., battery 10% or less) of the external electronic device. The electronic device (501) may provide a virtual vibration sound from the speaker (550) to provide a sense of immersion and feedback to the user based on the physical haptic vibration provided from the external electronic device (e.g., the first controller or the second controller) according to the vibration setting, thereby providing a tactile experience such as physical feedback.

[0091] According to one embodiment, the processor (510) can identify a type (e.g., mode) of a user interaction based on receipt of at least one user interaction. The processor (510) can identify the user interaction as a first type (e.g., first mode), as illustrated in FIG. 7A , if the user interaction is, for example, an interaction by the first controller (401) or the second controller (403). The processor (510) can identify the user interaction as a second type (e.g., second mode), as illustrated in FIG. 7B , if the user interaction is, for example, an interaction by the hand (601). The processor (510) can identify the user interaction as a third type (e.g., third mode), as illustrated in FIG. 7C , if the user interaction is, for example, an interaction by the first controller (401) or the second controller (403) and the hand (601) (e.g., a hybrid interaction). The processor (510) may identify the user interaction as an n-th type (e.g., n-th mode) when the user interaction is an interaction by an external electronic device (e.g., a keyboard, a mouse, an electronic pen, a smartphone, an AI device, or a watch) that does not include a haptic motor. According to one embodiment, the processor (510) may preset the first to n-th types according to the type of the input interface, and may also preset more types (e.g., modes) according to other types of the input interface.

[0092] According to one embodiment, the processor (510) may identify the occurrence of a passive interaction event or an active interaction event based on the user interaction type received. Here, according to one embodiment, the passive interaction event is an event that does not reflect the user's will, and may be, for example, an event related to a phone call, notification, video or music playback, or vibration due to a concentration mode, in which a physical collision may occur between a first virtual object and a second virtual object. For example, when a physical collision occurs and a passive interaction event occurs, the electronic device (501) may determine or generate a vibration pattern of different types depending on the texture of the surface, and output different virtual vibration sounds for the first virtual object and the second virtual object depending on the texture of the surface. According to one embodiment, an active interaction event is an event that reflects a user's will, and may be an event related to vibration of a motion for a virtual object corresponding to a user interaction received from at least one external electronic device (e.g., the first controller (401) and / or the second controller (403)) or the user's hand. Here, the interaction motion may mean an interaction for a virtual object displayed in a virtual reality space (610) corresponding to a motion input (e.g., a button input) by at least one external electronic device (e.g., the first controller (401) and / or the second controller (403)) and a motion input (e.g., a gesture input) by the user's hand. The event may mean information on an action received according to the interaction, and for example, when the electronic device (501) receives a user interaction for a button input according to the user's will, it may indicate that a vibration output for a virtual object corresponding to the user interaction is required.

[0093] According to one embodiment, the processor (510) may obtain information related to a virtual object provided in the virtual reality space (610) based on the identified type (e.g., information about a menu provided in the virtual reality space (e.g., a taskbar app icon menu), information about a function or content, information about a feature of an application (e.g., an app property), or at least one of a direction of an object, a distance of an object, a feature of an object (e.g., a 3D surface / material), or a type of an object, and layout information of content (spatial layout)).

[0094] According to one embodiment, the processor (510) may generate a vibration pattern based on the acquired information, and control the speaker (550) to output a virtual vibration sound corresponding to the generated vibration pattern. The processor (510) may control the communication circuit (540) to transmit or not transmit feedback information including the vibration pattern to an external electronic device (e.g., the first controller (401) or the second controller (403)) including a haptic motor so as to output vibration corresponding to the generated vibration pattern through the haptic motor according to the identified type. For example, the processor (510) may check the distances of other objects displayed in a virtual reality space based on the distance between the user and the object, set the vibration intensity according to the checked distance, and generate a vibration pattern with the set vibration intensity. Here, the vibration pattern can be generated by applying elements for at least one of frequency value (e.g., vibration intensity), vibration time and frequency type (e.g., resonant frequency (F(0)), low frequency (F(low)), medium frequency (F(mid)), high frequency (F(high)), alert frequency (F(alert))) or vibration interval.

[0095] According to one embodiment, when the processor (510) determines that at least one external electronic device (e.g., the first controller (401) and / or the second controller (403)) including a haptic motor among at least one input interface is being used, as illustrated in FIG. 8A, the processor (510) may control the communication circuit (540) to transmit feedback information including a vibration pattern generated to output vibration (e.g., haptic vibration) (803, 805) via the haptic motor while outputting a virtual vibration sound (801), to the external electronic device based on the identification of the first type. According to one embodiment, when the type of the user interaction is the first type, the processor (510) may set an output condition (e.g., output distribution) to synchronize the virtual vibration sound and the vibration so as to output the virtual vibration sound and the vibration simultaneously.

[0096] According to one embodiment, the processor (510) may control the speaker (550) to output only a virtual vibration sound (801) without transmitting feedback information to an external electronic device (e.g., the first controller (401) and / or the second controller (403)) so as not to output vibration through the haptic motor when the type of user interaction is the second type, as illustrated in FIG. 8b.

[0097] According to one embodiment, when the user interaction is of the third type, the processor (510) may output a virtual vibration sound through the speaker (550) and transmit feedback information through an external electronic device (e.g., the first controller (401) or the second controller (403)). Here, the feedback information may include a vibration pattern different from the virtual vibration sound. For example, when the processor (510) receives a user interaction (e.g., a first user interaction) according to a button input through the first controller (401) while the user is holding the first controller (401) with his / her left hand, and detects (or receives) a user interaction (e.g., a second user interaction) corresponding to a gesture by the right hand simultaneously or sequentially through the camera (530), the processor (510) may identify the user interaction as of the third type. The processor (510) may transmit feedback information including a first vibration pattern generated in response to a user interaction (e.g., a first interaction) to the first controller (401) upon identifying the third type, and may simultaneously or sequentially output a virtual vibration sound corresponding to a second vibration pattern generated in response to a user interaction (e.g., a second interaction) through the speaker (550). For example, when the speakers (550) are respectively arranged on the left and right members of the electronic device (501), the processor (510) may control the speaker (550) arranged on the right member to output a virtual vibration sound corresponding to the user's right-hand direction. For example, when a first interaction and a second interaction are received consecutively as user interactions, feedback information including a first vibration pattern generated in response to the first interaction can be transmitted, a virtual vibration sound corresponding to the first vibration pattern can be simultaneously output through a speaker (550), and only a virtual vibration sound corresponding to the second vibration pattern generated in response to the second interaction can be output through the speaker (550).

[0098] According to one embodiment, the processor (510) may generate a vibration pattern in response to the received user interaction when the type of user interaction is an n-th type, which is an interaction by an external electronic device (e.g., a keyboard, a mouse, or an electronic pen) that does not include a haptic motor, and output only a virtual vibration sound corresponding to the generated vibration pattern through the speaker (550).

[0099] According to one embodiment, the processor (510) may adjust the intensity of vibration output through the haptic motor of the first controller (401) or the second controller (403) and / or the intensity of virtual vibration sound output through the speaker (550) based on information related to a virtual object provided in the virtual reality space. Here, the processor (510) may adjust the intensity of vibration and / or the intensity of virtual vibration when outputting the intensity of vibration and / or the intensity of virtual vibration with a generated vibration pattern, or outputting the intensity of vibration and / or the intensity of virtual vibration with a vibration pattern that does not consider a change in the position of the user or the position of the object. According to one embodiment, the processor (510) may adjust the intensity of vibration and / or the intensity of virtual vibration based on a change in the position of the user or the position of the object (e.g., the distance between the user and the object or the direction of the object with respect to the position of the user) while outputting the intensity of vibration and / or the intensity of virtual vibration with the generated vibration pattern.

[0100] According to one embodiment, the processor (510) may adjust the intensity of the vibration output or the intensity of the virtual vibration sound output in proportion to the distance between the user and an object displayed in the virtual reality space. For example, when the distance becomes closer, the processor (510) may adjust the intensity of the vibration output or the intensity of the virtual vibration sound output so that it becomes weaker in proportion to the distance (e.g., lower than a set vibration intensity value or an intensity value of the virtual vibration sound). For example, when the distance becomes farther, the processor (510) may adjust the intensity of the vibration output or the intensity of the virtual vibration sound output so that it becomes stronger in proportion to the distance (e.g., higher than a set vibration intensity value or an intensity value of the virtual vibration sound). According to one embodiment, the processor (510) may adjust the intensity of the vibration output or the intensity of the virtual vibration sound output in inverse proportion to the distance between the user and an object displayed in the virtual reality space. For example, when the distance becomes closer, the processor (510) can adjust the intensity of the output vibration or the intensity of the output virtual vibration sound to become stronger in inverse proportion to the distance (e.g., to be higher than the set vibration intensity value or the intensity value of the virtual vibration sound). For example, when the distance becomes farther, the processor (510) can adjust the intensity of the output vibration or the intensity of the output virtual vibration sound to become weaker in inverse proportion to the distance (e.g., to be lower than the set vibration intensity value or the intensity value of the virtual vibration sound).

[0101] According to one embodiment, the processor (510) may adjust the intensity of the output vibration or the intensity of the output virtual vibration sound based on the direction of the object displayed in the virtual reality space. The processor (510) may identify the direction of the object based on the current location of the user. For example, if the speakers (550) are respectively disposed on the left and right members of the electronic device (501), the processor (510) may adjust the intensity of the virtual vibration sound output through the speaker (550) disposed in the direction corresponding to the direction of the identified object to be greater than a specified threshold value (e.g., the intensity of the virtual vibration sound being output or the intensity of the virtual vibration sound set in the vibration pattern) or greater than the intensity of the virtual vibration sound output through the speaker (550) disposed in the opposite direction. Conversely, the intensity of the virtual vibration sound output through the speaker (550) disposed in the opposite direction may be adjusted to be lower than the intensity of the virtual vibration sound output through the speaker (550) disposed in the direction corresponding to the direction of the identified object. For example, when vibration is output through the first controller (401) and the second controller (403) including haptic motors, the processor (510) can adjust the intensity of the vibration output through the first controller (401) held by the hand in the direction corresponding to the direction of the identified object to be greater than a specified threshold value (e.g., the intensity of the vibration being output or the intensity of the vibration set in the vibration pattern) or the intensity of the vibration output through the second controller (403) held by the hand in the opposite direction, and transmit feedback information including the adjusted vibration intensity value to the first controller (401). Conversely, the intensity of the virtual vibration sound output through the second controller (403) can be adjusted to be lower than the intensity of the virtual vibration sound output through the first controller (401).

[0102] According to one embodiment, the processor (510) can finely adjust the vibration intensity by adjusting complex elements (e.g., a specified vibration intensity value and a sound amplification value) for the purpose of an alert according to a notification event or according to an event that plays audio (e.g., outputs music, sound of video content, or sound of a game). For example, the processor (510) can adjust (e.g., adjust to a high level) the vibration intensity or the virtual vibration sound intensity to provide a notification (e.g., alert) about an incoming call. For example, the processor (510) can adjust (e.g., adjust to a high level) the vibration intensity or the virtual vibration sound intensity to provide a notification alert about functions or applications provided in a virtual reality space. For example, the processor (510) can adjust (e.g., adjust to a high level) the vibration intensity or the virtual vibration sound intensity to provide a notification about a user interaction, such as touching, dragging, or touching and releasing a virtual object provided in a virtual reality space. When the electronic device (501) provides an alert, it may provide a sound for the alert along with a vibration or virtual vibration sound to increase the user's awareness of the occurrence of an event.

[0103] According to one embodiment, the processor (510) can control the communication circuit (540) to identify a grip interaction when the user is holding and using the first controller (401) and / or the second controller (403) with a hand, set the intensity of the vibration to a threshold value (e.g., the vibration intensity set in the generated vibration pattern or the reference vibration intensity set in the device) or a virtual vibration sound, and transmit feedback information including the lowered vibration intensity to the first controller (401) and / or the second controller (403).

[0104] According to one embodiment, when the processor (510) identifies that the first controller (401) and / or the second controller (403) is in a low power mode, the processor (510) can transmit feedback information to control the haptic motor of the first controller (401) and / or the second controller (403) not to output vibration, and control the speaker (550) to output only a virtual vibration sound.

[0105] According to one embodiment, the processor (510) can determine whether the first controller (401) and / or the second controller (403) are in use. According to one embodiment, the processor (510) can determine that the first controller (401) and / or the second controller (403) are not in use if it is determined that the first controller (401) and / or the second controller (403) has not moved for a specified period of time. According to one embodiment, the processor (510) can determine whether the first controller (401) and / or the second controller (403) are in use based on sensing information acquired through a sensor included in the first controller (401) and / or the second controller (403). For example, the sensing information may include acceleration sensor information and / or gyro sensor information. According to one embodiment, the processor (510) may determine that the first controller (401) and / or the second controller (403) is not in use when the first controller (401) and / or the second controller (403) is confirmed to be placed on the ground through the camera (530). According to one embodiment, the processor (510) may determine whether the first controller (401) and / or the second controller (403) is gripped by the user based on sensing information obtained through a grip sensor included in the first controller (401) and / or the second controller (403).

[0106] According to one embodiment, the display (520) can display an object representing at least one input interface (e.g., a first controller (401) and a second controller (403), another input interface (e.g., a keyboard, a mouse, an electronic pen, or a smart phone), or a user's hand) under the control of the processor (510). The display (520) can display a virtual object under the control of the processor (510). For example, the virtual object can include a default menu or a universal menu provided by the electronic device (501). The universal menu can include a menu that can execute a function that can execute an application installed in the wearable electronic device (501), a function that can display devices (e.g., the first controller (401), the second controller (403)) that are communicatively connected to the wearable electronic device (501), and a function that can display a remaining battery level of the electronic device (501). Not limited thereto, the universal menu may include menus that provide various other functions.

[0107] FIG. 9 is a diagram showing an example configuration of a software module of an electronic device according to various embodiments.

[0108] Referring to FIGS. 5 and 9, an electronic device (501) according to an embodiment may implement a software module (901) (e.g., a program (140) of FIG. 1) for outputting a virtual vibration sound. A memory (130) of the electronic device (101) may store commands (e.g., instructions) to implement the software module (901) illustrated in FIG. 9. At least one processor (510) may execute commands stored in a memory (e.g., the memory (130) of FIG. 1 and the memory (560) of FIG. 5) to implement the software module (901) illustrated in FIG. 9, and may control hardware (e.g., the display module (160), audio module (170), sensor module (176), or communication module (190) of FIG. 1) associated with a function of the software module (901).

[0109] Referring to FIG. 9, a software module (901) of an electronic device (501) according to an embodiment may be configured to include a kernel (or HAL) (910), a framework (e.g., middleware (144) of FIG. 1) (920), and an application (930) (e.g., application (146) of FIG. 1). At least a portion of the software module (901) may be preloaded on the electronic device (101) or may be downloadable from a server (e.g., server (108)).

[0110] According to one embodiment, the kernel (910) includes, for example, a module (3) associated with a vibration module. rdThe kernel (910) may be configured to include a device with a vibrator (911), a vibration module of the device (vibrator of the device) (913). The kernel (910) may include, for example, a system resource manager or a device driver, and is not limited thereto and may be configured to further include other modules. The system resource manager may perform at least one of control, allocation, or recovery of system resources. The device driver may include, for example, a display driver, a camera driver, a Bluetooth driver, a shared memory driver, a USB driver, a keypad driver, a WIFI driver, an audio driver, or an IPC (inter-process communication) driver.

[0111] According to one embodiment, the framework (920) may be configured to include, for example, modules necessary for outputting a virtual vibration sound (e.g., an XR-related module (921), an input-related module (922), a system vibrator-related module (923), and an XR control-related module (924)), but is not limited thereto and may further include other modules. The framework (920) may provide functions commonly required by the application (930) or provide various functions to the application (930) through an application programming interface (API) (not shown) so that the application (930) can efficiently use limited system resources within the electronic device (101). As an event for user interaction, haptic feedback may be configured to be generated in the control module (XR controller tracking service) (924) of the software module (901) of the electronic device (501). When the software module (901) receives vibration request information (request vibrate information), the input manager (925) determines vibration (Haptic), and when the application (930) generates vibration (e.g., virtual vibration), the system vibration-related module (923) can generate vibration feedback (haptic feedback). The software module (901) can generate vibration (haptic vibration) in the vibration service (926) (vibrator service). When vibration occurs in the 2D application, the vibration service (926) can transmit information about the vibration (haptic information) to the control module (924).

[0112] According to one embodiment, the framework (920) may include modules that combine various functions of the aforementioned components. The framework (920) may provide specialized modules for each type of operating system to provide differentiated functionality. The framework (920) may dynamically delete some existing components or add new components.

[0113] According to one embodiment, the application (930) may be configured to include related applications (e.g., modules, managers, or programs) (931, 932, 933, 934) for outputting a virtual vibration sound from the electronic device (501). The application (930) may further be configured to include a module (or application) (not shown) for wireless communication with an external electronic device (e.g., the first controller (401), the second controller (403) of FIG. 4). The application (930) may include an application received from an external electronic device (e.g., the server (108) or the electronic device (102, 104)). According to one embodiment, the application (930) may include a preloaded application or a third party application downloadable from a server. The components and names of the components of the software module (901) according to the illustrated embodiment may vary depending on the type of operating system. According to one embodiment, at least a portion of the software module (901) may be implemented as software, firmware, hardware, or a combination of at least two or more thereof. At least a portion of the software module (901) may be implemented (e.g., executed) by, for example, a processor (e.g., an AP). At least a portion of the software module (901) may include, for example, at least one of a module, a program, a routine, a set of instructions, or a process for performing at least one function.

[0114] According to one embodiment, the software module (901) of the electronic device (501) may be configured to simultaneously generate a virtual vibration sound together with the audio (or sound source) when playing audio (or sound source) (e.g., outputting sound of music, video content, or game). For example, when playing a sound source file including both audio data and haptic data (or vibration data) (e.g., including haptic data in a specific channel of the sound source file), the electronic device may transmit the audio data to the audio driver of the software module (901) and transmit the haptic data to the vibration driver (e.g., haptic driver) of the software module (901) to simultaneously output a virtual vibration sound together with the audio source. For example, when a sound source file contains only audio data, haptic data reflecting the audio data can be generated by a haptic generation module (e.g., a vibration service (926)) of a software module (901), and the generated haptic data can be transmitted to a vibration driver to be output as a virtual vibration sound through a speaker (550). For example, when a sound source file contains only audio data, audio data can be output as high-quality data by a vibration driver of a software module (901), and the high-quality data output by the vibration driver can be output as a virtual vibration sound through a speaker (550).

In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0131] Referring to FIG. 10, in operation 1001, an electronic device according to an embodiment (e.g., an electronic device (101) of FIG. 1, a wearable electronic device (200) of FIG. 2, a wearable electronic device (300) of FIGS. 3A to 3C, an electronic device (501) of FIG. 5) may provide a virtual reality space through a display (e.g., a display module (160) of FIG. 1, a display member (201) of FIG. 2, a display (321) of FIG. 3, a display (520) of FIG. 5)) while a user is wearing the electronic device, and may display a virtual object on the virtual reality space.

[0132] In operation 1003, an electronic device according to an embodiment may receive a user interaction via at least one input interface. The electronic device may be connected to the at least one user interface using a short-range communication technology (e.g., Bluetooth low energy (BLE) or WiFi) or a wired communication. Here, the at least one input interface may be at least one external electronic device including a haptic motor (e.g., the first controller (401) or the second controller (403) of FIGS. 4 and 6A), a part of a user's body (e.g., a hand (601) of FIG. 6C), or at least one external electronic device not including a haptic motor (e.g., a keyboard (603) of FIG. 6C and / or an electronic pen (605) of FIG. 6D). According to an embodiment, the electronic device may receive the user interaction from at least one external electronic device including a haptic motor or from at least one external electronic device not including a haptic motor via a communication circuit. According to one embodiment, the electronic device can detect a gesture by a user's hand or an external electronic device (e.g., the first controller (401) or the second controller (403) of FIGS. 4 and 6A) through a camera (e.g., the camera (530) of FIG. 5) or at least one sensor (e.g., a motion sensor), and identify (e.g., receive or obtain) a user interaction corresponding to the detected gesture.

[0133] In operation 1005, an electronic device according to an embodiment may identify a type of user interaction. The electronic device may identify the user interaction as a first type (e.g., a first mode) if the user interaction is, for example, an interaction by a first controller and / or a second controller. The electronic device may identify the user interaction as a second type (e.g., a second mode) if the user interaction is, for example, an interaction by a user's hand. The electronic device may identify the user interaction as a third type (e.g., a third mode) if the user interaction is, for example, an interaction by a first controller or a second controller and a user's hand (e.g., a hybrid interaction). The electronic device may identify the user interaction as an n-th type (e.g., an n-th mode) if the user interaction is, for example, an interaction by an external electronic device (e.g., a keyboard, a mouse, an electronic pen, a smartphone, an AI device, or a watch) that does not include a haptic motor. According to one embodiment, the electronic device may preset the first to n-th types according to the type of the input interface, and may also preset more types (e.g., modes) according to other types of the input interface. According to one embodiment, the electronic device may identify the occurrence of a passive interaction event or an active interaction event according to a received user interaction based on the user interaction type. Here, the passive interaction event is an event that does not reflect the user's will, and may be, for example, an event related to a phone call, a notification, video or music playback, or vibration due to a concentration mode, in which an interaction action between a first virtual object and a second virtual object may cause a physical collision. The active interaction event is an event that reflects the user's will, and may be an event related to vibration of an action for a virtual object corresponding to a user interaction received from at least one external electronic device (e.g., the first controller (401) and / or the second controller (403)) or the user's hand.

[0134] In operation 1007, the electronic device according to one embodiment may obtain information related to a virtual object provided in a virtual reality space based on the identified type. For example, the information related to the virtual object may include at least one of a menu (e.g., a taskbar app icon menu) provided in the virtual reality space, information about a function or content, information about a feature of an application (e.g., an app property), or a direction of an object, a distance of an object, a feature of an object, or a type of an object. As illustrated in FIG. 11, when the received user interaction is, for example, a button input operation (1110) of an external electronic device (401) or a gesture (1120) by a user's hand (601), the electronic device according to one embodiment may identify a virtual object (1101) that is operated or indicated by the button input operation (1110) of the external electronic device (401) or the gesture (1120) by the user's hand (601), and obtain information related to the identified virtual object (1101). As illustrated in FIG. 12a, an electronic device (501) according to an embodiment can obtain information related to a first object (e.g., a taskbar app icon menu) (1201), a second object (e.g., a slide control for volume control) (1203), and / or a third object (e.g., an app property icon running on the dash) (1205) according to a user interaction by at least one external electronic device (401, 403). As illustrated in FIG. 12b, an electronic device (501) according to an embodiment can obtain information related to a first object (e.g., a taskbar app icon menu) (1201), a second object (e.g., a slide control for volume control) (1203), and / or a third object (e.g., an app property icon running on the dash) (1205) according to a user interaction by a user's hand (601).

[0135] In operation 1009, an electronic device according to an embodiment may generate a vibration pattern based on information related to a virtual object. The electronic device may determine distances to other objects displayed in a virtual reality space based on a distance between a user and the object, set a vibration intensity according to the determined distance, and generate a vibration pattern with the set vibration intensity. Here, the vibration pattern may be generated by applying an element for at least one of a frequency value (e.g., vibration intensity), a vibration time, a frequency type (e.g., at least one of a resonant frequency (F(0)), a low frequency (F(low)), a middle frequency (F(mid)), a high frequency (F(high)), or an alert frequency (F(alert))), or a vibration interval.

[0136] In operation 1011, an electronic device according to an embodiment may check whether a user is using at least one external electronic device (e.g., the first controller (401) and / or the second controller (403) of FIG. 4). If the user is using at least one external electronic device, operation 1015 may be performed. Otherwise, the electronic device may perform operation 1013.

[0137] In operation 1013 (operation 1011-No), the electronic device according to one embodiment may output a virtual vibration sound corresponding to a vibration pattern generated based on information related to a virtual object through a speaker of the electronic device (e.g., speaker (550) of FIG. 5). Thereafter, the operation may be terminated. According to one embodiment, the electronic device may identify that the type of user interaction is the second type based on confirmation that the user does not use at least one external electronic device, and may output only the virtual vibration sound through the speaker without transmitting feedback information to the external electronic device (e.g., first controller (401) and / or second controller (403) of FIG. 4) so ​​as not to output vibration through the haptic motor.

[0138] In operation 1015 (operation 1011 - example), an electronic device according to an embodiment may transmit feedback information including a vibration pattern to at least one external electronic device through a communication circuit of the electronic device (e.g., communication circuit (540) of FIG. 5) to output vibration through a haptic motor while outputting a virtual vibration sound based on whether a user is using at least one external electronic device. Thereafter, the operation may be terminated.

[0139] In the above operation 1015, if the electronic device according to one embodiment determines that at least one external electronic device (e.g., the first controller (401) and / or the second controller (403)) including a haptic motor among at least one input interface is being used, the electronic device may identify that the type of the user interaction is the first type, and based on the identification of the first type, transmit feedback information including a vibration pattern generated to output vibration (e.g., haptic vibration) through the haptic motor while outputting a virtual vibration sound to the external electronic device. According to one embodiment, when the type of the user interaction is the first type, the electronic device may set an output condition (e.g., output distribution) to synchronize the virtual vibration sound and the vibration so as to output the virtual vibration sound and the vibration simultaneously.

[0140] FIG. 13 is a drawing showing an example of an operating method in an electronic device according to one embodiment.

[0141] Referring to FIGS. 10 and 13, in operation 1015 or separately from operation 1015, when an electronic device (501) according to an embodiment determines that a user is using at least one external electronic device (401) (e.g., the first controller (401) of FIG. 4), the electronic device (501) determines whether the received user interaction is a third type of a hybrid type including a first interaction (e.g., a control signal) by the external electronic device (401) and a second interaction (e.g., a gesture of grabbing a virtual object (1311) displayed on a virtual reality space (610) by the hand) by the user's hand, and sets and performs an output condition according to the third type. According to one embodiment, the electronic device (501) may transmit feedback information including a first vibration pattern generated in response to a user interaction (e.g., a first interaction) to the external electronic device (401) upon identifying the third type, and may simultaneously or sequentially output a virtual vibration sound corresponding to a second vibration pattern generated in response to the user interaction (e.g., a second interaction) through a speaker. For example, when speakers are respectively arranged on the left and right members of the electronic device, the electronic device may control the speaker arranged on the right member to output a virtual vibration sound corresponding to the user's right-hand direction. For example, when the first interaction and the second interaction are received consecutively as user interactions, the electronic device may transmit feedback information including the first vibration pattern generated in response to the first interaction, simultaneously output the virtual vibration sound corresponding to the first vibration pattern through the speaker, and sequentially output only the virtual vibration sound corresponding to the second vibration pattern generated in response to the second interaction through the speaker.

[0142] According to one embodiment, the electronic device can generate a vibration pattern in response to a received user interaction, and output only a virtual vibration sound corresponding to the generated vibration pattern through a speaker, when the type of user interaction is an n-th type that is an interaction by an external electronic device (e.g., a keyboard, a mouse, or an electronic pen) that does not include a haptic motor.

[0143] According to one embodiment, the electronic device can determine whether the first controller and / or the second controller is in use. According to one embodiment, if the electronic device determines that the first controller and / or the second controller is not in use when it determines that there is no movement for a specified period of time, the electronic device can determine whether the first controller and / or the second controller is in use. According to one embodiment, the electronic device can determine whether the first controller and / or the second controller is in use based on sensing information obtained through a sensor included in the first controller and / or the second controller. For example, the sensing information may include acceleration sensor information and / or gyro sensor information. According to one embodiment, the electronic device can determine whether the first controller and / or the second controller is not in use when it determines through a camera that the first controller and / or the second controller is placed on the ground. According to one embodiment, the electronic device can determine whether the first controller and / or the second controller is gripped by a user based on sensing information obtained through a grip sensor included in the first controller and / or the second controller.

[0144] FIGS. 14A to 14C are diagrams illustrating examples for generating a vibration pattern in an electronic device according to one embodiment.

[0145] Referring to FIGS. 14A to 14C, according to one embodiment, when generating a vibration pattern based on information related to a virtual object in operation 1009 of FIG. 10 described above, the electronic device may apply an element for at least one of a frequency value (e.g., vibration intensity), a vibration time, and a frequency type (e.g., at least one of a resonant frequency (F(0)), a low frequency (F(low)), a middle frequency (F(mid)), a high frequency (F(high)), or an alert frequency (F(alert)))) or a vibration interval time to generate various combinations of vibration patterns (e.g., vibration patterns A to M of FIG. 14A). Here, the resonant frequency (F(0)) is applied to haptic feedback that requires fast and accurate interaction, such as an input device (SIP) and a dialer, and may be applied to secure the best vibration force even in a short duration. The alert frequency (F(alert)) is, for example, a vibration frequency for incoming calls / notifications, and can be derived through a user experience / performance evaluation and applied to the final tuning frequency. The low frequency (F(low)) can be applied to fingerprint recognition errors and input device scale keys, and can be provided as a vibration that minimizes discomfort. The middle frequency (F(mid)) can be applied to functions such as low battery and smart alert, and can be provided as a heavy and soft vibration. The high frequency (F(high)) can be applied to camera shutter, screen capture, and cases of no input, and can be provided as a vibration with an aperture feel and edge.As illustrated in Fig. 14b, in each pattern code (N, O, P), the first number indicates the vibration duration (e.g., 7 ms) indicating how many seconds of the pattern code the vibration will occur, the second and third numbers indicate that 2000 vibrations will occur for 10000 ms, and the last number may indicate a unique ID of the vibration (e.g., 1 or 0).

[0146] As shown in FIGS. 14a and 14c, vibration patterns A, B, and F represent vibration categories (haptics) for haptic vibrations, and the electronic device can generate the vibration pattern to output one vibration with, for example, a resonant frequency (F(0)), a frequency value of 180 Hz, and a vibration time of 7 ms.

[0147] As illustrated in FIGS. 14A and 14C, vibration patterns C, D, E, and G represent vibration categories (operations) according to operations, and the electronic device can generate vibration patterns with, for example, one of low frequency (F(low)), medium frequency (F(mid)), or high frequency (F(high)), one of 120 Hz, 150 Hz, or 200 Hz, a combination of various vibration times, and a combination of various vibration interval times. For example, pattern C can be set to output one vibration with a vibration time of 100 ms (0 ms(off)->100 ms(on)). For example, pattern D can be set to output one vibration with a vibration time of 100 ms (0 ms(off)->100 ms(on)), and then output two vibrations with an interval time of 50 ms and then 30 ms (50 ms(off)->30 ms(on)). For example, the E pattern can be set to output one vibration with a vibration time of 10ms (0ms(off)->10ms(on)), and then output two vibrations with an interval time of 60ms and then 15ms apart (60ms(off)->15ms(on)). For example, the G pattern can be set to output one vibration with a vibration time of 75ms (0ms(off)->10ms(on)), and then output two vibrations with an interval time of 25ms and then 75ms apart (60ms(off)->15ms(on)), and then not output any vibration with an interval time of 300ms (off).

[0148] As illustrated in FIGS. 14A and 14C, vibration patterns H, I, J, K, L, and M represent vibration categories (alerts) according to notifications, and the electronic device can generate vibration patterns with, for example, an alert frequency (F (alert)), 157.5 Hz, a combination of various vibration times, or a combination of various vibration interval times. For example, the H pattern can be set to output vibration with a vibration time of 500 ms (on). For example, the I pattern can be set to output vibration once with a vibration time of 150 ms (0 ms (off)->150 ms (on)), output vibration twice with an interval time of 80 ms and then 150 ms (80 ms (off)->150 ms (on)), and not to output vibration for 1200 ms (off). For example, the J pattern can be set to output one vibration with a vibration time of 250ms (0ms(off)->250ms(on)), output two vibrations with an interval time of 250ms each (250ms(off)->250ms(on)), and not output vibration with 250ms(off). For example, the K pattern can be set to output one vibration with a vibration time of 1500ms (0ms(off)->1500ms(on)), and not output vibration with 2000ms(off). For example, the L pattern can be set to output one vibration with a vibration time of 250ms (0ms(off)->250ms(on)), two vibrations with an interval time of 250ms and then 250ms (250ms(off)->250ms(on)), three vibrations with an interval time of 250ms and then 250ms (250ms(off)->250ms(on)), and no vibration with an interval time of 750ms (off).

[0150] As illustrated in FIG. 15A, an electronic device according to one embodiment may generate a vibration pattern representing a simple waveform that occurs when a user interaction is received for a gesture (e.g., grip, pinch) by a user's hand.

When the type is the first type or the third type, the electronic device may transmit feedback information including a vibration pattern generated to output vibration (e.g., haptic vibration) through the haptic motor while outputting a virtual vibration sound to the at least one external electronic device. At this time, the electronic device may synchronize the virtual vibration sound output through the speaker and the vibration output through the haptic motor, and transmit feedback information including information about the vibration pattern and synchronization generated to simultaneously output the virtual vibration sound and the vibration to the at least one external electronic device. Accordingly, the electronic device can output a virtual vibration sound through a speaker, and at least one external electronic device can output a vibration through a haptic motor in synchronization with the virtual vibration sound.

[0158] FIG. 18 is a diagram illustrating an example of operation in a low power mode in an electronic device according to one embodiment.

[0159] Referring to FIG. 18, when an electronic device (501) according to one embodiment identifies that the first controller (401) and / or the second controller (403) is in a low power mode (e.g., a state where the battery is less than 10%), the electronic device may transmit feedback information to control the haptic motor of the first controller (401) and / or the second controller (403) not to output vibration, and control the speaker to output only a virtual vibration sound.

[0160] According to one embodiment, the electronic device may adjust the intensity of vibration output through a haptic motor of the first controller or the second controller and / or the intensity of virtual vibration sound output through a speaker based on information related to a virtual object provided in the virtual reality space. Here, the electronic device may adjust the intensity of vibration and / or the intensity of virtual vibration when outputting the intensity of vibration and / or the intensity of virtual vibration with a generated vibration pattern, or outputting the intensity of vibration and / or the intensity of virtual vibration with a vibration pattern that does not consider a change in the position of the user or the position of the object. According to one embodiment, the electronic device may adjust the intensity of vibration and / or the intensity of virtual vibration based on a change in the position of the user or the position of the object (e.g., a distance between the user and the object or a direction of the object with respect to the position of the user) while outputting the intensity of vibration and / or the intensity of virtual vibration with the generated vibration pattern.

[0161] According to one embodiment, the electronic device can adjust the intensity of the vibration output or the intensity of the virtual vibration sound output in proportion to the distance between the user and an object displayed in the virtual reality space. For example, when the distance decreases, the electronic device can adjust the intensity of the vibration output or the intensity of the virtual vibration sound output so that it becomes weaker in proportion to the distance. For example, when the distance increases, the electronic device can adjust the intensity of the vibration output or the intensity of the virtual vibration sound output so that it becomes stronger in proportion to the distance.

[0162] According to one embodiment, the electronic device can adjust the intensity of the output vibration or the intensity of the output virtual vibration sound based on the direction of an object displayed in a virtual reality space. The electronic device can identify the direction of the object based on the current location of the user. For example, if speakers are respectively placed on the left and right members of the electronic device, the electronic device can adjust the intensity of the virtual vibration sound output through the speaker placed in the direction corresponding to the direction of the identified object to be greater than a specified threshold value (e.g., the intensity of the virtual vibration sound being output or the intensity of the virtual vibration sound set in the vibration pattern) or greater than the intensity of the virtual vibration sound output through the speaker placed in the opposite direction. Conversely, the intensity of the virtual vibration sound output through the speaker placed in the opposite direction can be adjusted to be lower than the intensity of the virtual vibration sound output through the speaker placed in the direction corresponding to the direction of the identified object. For example, when vibration is output through a first controller and a second controller including a haptic motor, the electronic device can adjust the intensity of the vibration output through the first controller held by a hand in a direction corresponding to the direction of the identified object to be greater than a specified threshold value (e.g., intensity of the vibration being output or intensity of the vibration set in the vibration pattern) or greater than the intensity of the vibration output through the second controller held by the hand in the opposite direction, and transmit feedback information including the adjusted vibration intensity value to the first controller. Conversely, the intensity of a virtual vibration sound output through the second controller can be adjusted to be lower than the intensity of the virtual vibration sound output through the first controller.

[0163] According to one embodiment, the electronic device may finely adjust the vibration intensity by adjusting complex factors (e.g., a specified vibration intensity value and a sound amplification value) for the purpose of an alert according to a notification event or according to an event that plays audio (e.g., outputs music, sound of video content, or sound of a game). For example, the electronic device may adjust (e.g., adjust to a high level) the vibration intensity or the virtual vibration sound intensity to provide a notification alert for an incoming call. For example, the electronic device may adjust (e.g., adjust to a high level) the vibration intensity or the virtual vibration sound intensity to provide a notification alert for a function or application provided in a virtual reality space. For example, the electronic device may adjust (e.g., adjust to a high level) the vibration intensity or the virtual vibration sound intensity to provide a notification for a user interaction, such as touching, dragging, or touch-releasing a virtual object provided in a virtual reality space. When an electronic device provides an alert, it may also provide a sound for the alert along with vibration or a virtual vibration sound to increase the user's awareness of the occurrence of the event.

[0164] According to one embodiment, the electronic device can identify a grip interaction when the user is holding and using the first controller and / or the second controller with a hand, set the intensity of the vibration to a threshold (e.g., a vibration intensity set in a generated vibration pattern or a reference vibration intensity set in the device) or a virtual vibration sound, and control the communication circuit to transmit feedback information including the lowered vibration intensity to the first controller and / or the second controller.
