Description

Apparatus for Examining Eye Health and Method for Operating Thereof The following disclosure relates to an eye health examination device and a method of operation thereof. The increasing use of digital devices has led to a rise in various eye diseases, such as eye strain, dry eyes, and vision loss. Early diagnosis and prevention are crucial for these conditions, yet in most cases, it is difficult for users to recognize any abnormalities before visiting a hospital. Traditionally, users had to visit a hospital in person to undergo examinations to check for eye health issues. Recently, however, smartphone applications for eye health checkups are frequently used. An eye health examination device according to one embodiment includes: a distance sensor for measuring the distance between a user and the eye health examination device; a camera; a display for outputting a target for eye health examination; a communication circuit for receiving user input corresponding to the output target from an external controller device connected to the eye health examination device; and a processor, wherein the processor determines whether the measured distance between the user and the eye health examination device satisfies a defined standard, and the display outputs a target sized based on the measured distance or outputs guide content if the measured distance does not satisfy the defined standard, and outputs a target of a defined standard size if the measured distance satisfies the defined standard. The camera acquires an image of the user when the measured distance satisfies the defined criteria or when the scaled target is output, and the processor recognizes an eye mask for the user's eye health examination from the acquired image, recognizes the user's eye being examined between the left and right eyes based on the position of the recognized eye mask, and determines the user's eye health examination result based on the result of the recognition and the user input. It may further include a microphone for collecting voice-based user input corresponding to the outputted target. The above processor, when voice-based user input is collected through a microphone, removes noise from the voice-based user input, extracts at least one of the user's speech information regarding at least one of the numbers, characters, or symbols recognized by the user based on the visual target from the noise-removed user input, or at least one of the user's speech information corresponding to the inability to recognize the visual target, and determines the user's eye health test result based on at least one of the user's speech information regarding at least one of the numbers, characters, or symbols recognized by the user or the user's speech information corresponding to the inability to recognize the visual target. The above user input includes at least one of the user's selection information regarding at least one of a number, character, or symbol recognized by the user based on the above visual acuity chart, or at least one of the user's selection information corresponding to the inability to recognize the above visual acuity chart, and the processor can determine the user's eye health test result based on the user's selection information regarding at least one of a number, character, or symbol recognized by the user based on the above visual acuity chart, or the user's selection information corresponding to the inability to recognize the above visual acuity chart. The above external controller device may receive input of at least one of the user's selection information regarding at least one of a number, character, or symbol recognized by the user based on the above target, or at least one of the user's selection information corresponding to the inability to recognize the above target. The processor can recognize the eye mask by detecting recognition text written on the eye mask from the image, recognize the position of the eye mask by recognizing which eye the recognized eye mask is mounted in front of the user's left eye or right eye, and determine the user's eye undergoing an eye health examination, either the user's left eye or right eye, based on the position of the recognized eye mask. The processor may determine the position of the eye covering in front of the left eye and determine the eye of the user undergoing the eye health examination as the right eye when the recognized eye covering is recognized as being mounted in front of the user's left eye, and determine the position of the eye covering in front of the right eye and determine the eye of the user undergoing the eye health examination as the left eye when the processor recognizes that the recognized eye covering is mounted in front of the right eye. The distance sensor described above includes a LiDAR sensor and can measure the measured distance between the user and the eye health examination device using the Time-of-Flight (ToF) method. The above display may output guide conte
