The overall operation of the present invention will be described in detail with reference to FIG. 2.

2 is a flowchart illustrating an embodiment of an eye test in a wireless communication terminal according to the present invention.

First, a user inputs an eye test request signal through an input device (keypad) 17, and then places the wireless communication terminal at a predetermined distance to perform eye test. In this case, the user may measure the right eye and the left eye in order according to the guidance of the wireless communication terminal, and the result may be checked by the user through the display device (LCD) 16 and / or the voice output device 15. Of course, since it is stored in the storage device 14 it is possible to continuously manage the vision.

That is, when the operation / control device 12 receives the vision test request signal through the input device (keypad) 17 (201), the distance sensor 10 is operated to operate the current user and the display device (LCD) 16. Received a distance measurement signal with the (202).

In operation 203, an eye test screen corresponding to the distance measurement signal received from the distance sensor 10 is output through the display device (LCD) 16. At this time, the visual inspection screen is a screen that can check the minimum size of the characters that can be read and determined at a certain distance, that is, the minimum legible (minimum legible), as shown in FIGS. 3 and 4. That is, the eye test screen may output the eye test table at a time as shown in FIG. 3 so that the user reads the text indicated by the pointer 31 aloud, as shown in FIG. 4. You can also print out small letters one by one and have the user read them aloud. In addition, the visual inspection screen may be a figure and a picture in addition to the character, and in this case, may answer "Yes", "No".

On the other hand, if the operation / control device 12 provides a specific visual acuity test character, and receives a user response signal from the voice recognition sensor 19 within a predetermined time, it is determined whether the answer is correct or incorrect (204). In this case, the incorrect answer includes not only the answer other than the correct answer but also the non-answer.

As a result of the determination (204), if the user response signal is the correct answer, it is checked whether the last level (the smallest size letter) is being examined (205), and if the current level is being examined, the current vision test The visual acuity test value corresponding to the size of the character is output to the display device (LCD) 16 and / or the audio output device 15 and recorded in the storage device 14 as a test history (date, right eye, left eye). (208). If it is not the last level (smallest sized character), the process proceeds to "203" and the next level (smaller sized) vision test character is output on the vision screen.

On the other hand, if the determination result 204, if the user response signal is incorrect, the total number of incorrect answers is increased (206), and it is determined whether the total number of incorrect answers exceeds a preset value (207). As a result of the determination 207, if the total number of incorrect answers does not exceed the preset value, the process proceeds to step " 203 " to output another visual inspection character of the same size to the visual inspection screen. If the total number of incorrect answers exceeds the preset value, the visual inspection value corresponding to the size of the current visual inspection character is output to the display device (LCD) 16 or the voice output device 15. The data is recorded in the storage device 14 as an inspection history (date, right vision, left vision) (208).

Processes "202" to "208" described above are performed for the right eye and the left eye, respectively. In addition, in the above process, the visual inspection screen progresses from low vision to high vision, but vice versa.

On the other hand, the inspection history stored in the storage device 14 can be retrieved by menu selection.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.
