For example, through a speaker disposed on a surface of the electronic device 101, the electronic device 101 may output a relatively stronger audio signal than an audio signal outputted through a speaker disposed on another surface opposite to the surface.
According to an embodiment, the electronic device 101 may obtain information related to distances d1, d2, and d3 matched to each of the visual objects 320. For example, the electronic device 101 may adjust audio signals matched to each of the visual objects 320 based on information related to the distances d1, d2, and d3. For example, the electronic device 101 may relatively strongly output an audio signal matched to the second visual object 323 identified as a relatively close distance d2, compared to audio signals matched to the first visual object 321 and audio signals matched to the third visual object 325. For example, the electronic device 101 may highly designate a level of an audio signal matched to the second visual object 323 and output, compared to a level of an audio signal matched to the first visual object 321 and a level of an audio signal matched to the third visual object 325.
As described above, according to an embodiment, the electronic device 101 may adjust intensity of audio signals matched to the visual objects 320 based on information related to the location of the visual objects 320. For example, the information related to the location may include information on distances between each of the visual objects 320 and the electronic device 101. For example, the information related to the location may include information related to azimuth angles 520 between the electronic devices 101 and each of the visual objects 320. For example, adjusting the intensity of the audio signals may include adjusting the level of the audio signals. The electronic device 101 may enhance the user experience of the electronic device 101 by adjusting the levels of the audio signals.

The photographing camera, the eye tracking camera 740-1, and the motion recognition camera 740-2 may be disposed in different positions on the frame 700 and perform different functions. The eye tracking camera 740-1 may output data indicating a gaze of the user wearing the electronic device 101. For example, the electronic device 101 may detect the gaze from an image including the user's eyes obtained through the eye tracking camera 740-1. An example in which the eye tracking camera 740-1 is disposed toward the user's right eye is illustrated in FIG. 7B, but embodiments are not limited thereto, and the eye tracking camera 740-1 may be disposed alone toward the user's left eye or may be disposed toward both eyes.
In an embodiment, the photographing camera may photograph an actual image or background to be matched with a virtual image to implement augmented reality or mixed reality content. The photographing camera may take an image of a specific object existing at a position viewed by the user and provide the image to the at least one display 210. The at least one display 210 may display one image in which information on the actual image or background including the image of the specific object obtained using the photographing camera and a virtual image provided through the at least one optical device 782 and 784 are overlapped. In an embodiment, the photographing camera may be disposed on the bridge 703 disposed between the first rim 701 and the second rim 702.
By tracking the gaze of the user wearing the electronic device 101, the eye tracking camera 740-1 may implement a more realistic augmented reality by matching the user's gaze with the visual information provided to the at least one display 210.

The motion recognition camera 740-2 may provide a specific event to a screen provided on the at least one display 210 by recognizing a movement of the user's whole or part of body, such as the user's torso, hand, or face. The motion recognition camera 740-2 may obtain a signal corresponding to a motion by gesture recognition of the user and provide a display corresponding to the signal to the at least one display 210. The processor may identify a signal corresponding to the operation and perform a designated function based on the identification.

FIG. 9 is an example of a flowchart of an operation of an electronic device, according to an embodiment. The electronic device of FIG. 9 is an example of the electronic device 101 of FIGS. 1, 2, 3, 5, 7A, 7B, 8A, and/or 8B. The electronic device of FIG. 9 is an example of the electronic device of FIGS. 4A, 4B, and/or 6. Operations of FIG. 9 may be executed by the processor 120 of FIGS. 1 and/or 2.

The electronic device may obtain the first audio signal based on obtaining the acoustic signal generated from the external object and sampling the acoustic signal. The electronic device may obtain a second audio signal based on a virtual object (e.g., the virtual object 321, 323, and 325 of FIG. 3). The electronic device may obtain the first audio signal based on the external object and the second audio signal based on the virtual object. The electronic device may identify the first audio signal obtained based on the external object and the second audio signal obtained based on the virtual object.
In operation 903, according to an embodiment, the electronic device may identify the first audio signal obtained based on the external object. Based on the first audio signal, the electronic device may obtain information related to a characteristic propagated in a space in which the electronic device is disposed. For example, information related to the characteristic propagated in the space in which the electronic device is disposed may be related to a reverberation characteristic in the space where the electronic device is disposed. For example, the reverberation characteristic may be associated with a reverberation time. For example, the reverberation characteristic may be related to the amplitude of the acoustic signal generated from the external object.
