[0033] In the sixth divided window, 0 may be used as a number 0, and . inside 0 may be used a number 0 or a period ..

[0034] In the embodiment, six divided display windows including alphabets or numbers are disposed. Accordingly, six detailed dials corresponding thereto may also be provided.

[0035] FIG. 3 is a diagram illustrating a process of inputting a character in the English input keyboard for a severe patient according to the embodiment of the present disclosure, and illustrates a process of inputting a single letter using the English input keyboard.

[0036] First, the conversation partner (guardian) of the patient presents the integrated dial 100 which is the first English input keyboard, as a location where the patient can see the English input keyboard for communication with the patient. The patient gazes at the divided display window inside the integrated dial 100 including a word or a number corresponding to a beginning of the intended word by moving the pupil to express the intended word. At this time, the guardian observes the movement of the pupil of the patient and recognizes the divided display window determined to be gazing by the patient.

[0037] For example, when a letter of LIKE is input, the patient will gaze at the fourth divided display window 140 at 8 o'clock including L, and the guardian presents the fourth detailed dial 141 including the detailed information of the corresponding fourth divided display window 140 to the patient. The patient will gaze again at the third sector 144 at 2 o'clock where L is positioned in the fourth detailed dial 141, and the guardian sees the patient's pupil movement and writes L in the character input unit 127. The input process for one alphabet may be performed through the above-described process.

[0038] Subsequently, the entire dial 100 may be presented to the patient again. The patient will move the pupil to gaze at the third divided display window 130 at 2 o'clock among the multiple divided display windows disposed on the integrated dial 100. When it is determined that the patient has gazed at the third divided display window 130, the guardian presents the third detailed dial 131 including the character information of the third divided display window 130 to the patient.

[0039] The patient will again gaze at the third sector 134 where I is located in the third detailed dial 131, and the guardian sees the patient's pupil movement and writes I in the character input unit 138. Accordingly, I is combined with L previously written, and thus, LI can be written. By repeating the same process for K and E, and thus, the word such as LIKE is completed.

[0040] As described above, in the English input keyboard of the present disclosure, based on the input method of the keyboard, desired characters of the patient are sequentially selected by the guardian according to the intention of the patient, and the selected character is input by the guardian. Accordingly, the word intended by the patient is completed, and thus, quick communication between the patient and the guardian can be achieved.

[0041] In the embodiment, considering that the total of the English alphabet and the Arabic numeral is 36, windows which can be selected in six directions based on the center of the English input keyboard are disposed to better recognize the gaze direction of the patient's pupil. That is, since the number of integrated dials and the number of windows disposed inside the detailed dial interlocked therewith are the same as each other, the patient can keep the movement of the pupil the same on the two dials. Accordingly, the guardian is easy to ascertain the position of the pupil of the patient, and the character intended by the patient can be more accurately selected.

[0042] In the embodiment, a method is used, in which the guardian presents an English input keyboard to a patient, an alphabet or numeric window selected by the patient is recognized by the guardian, and the corresponding English input keyboard is presented to the patient again. The English input keyboard presented to the patient may be made of paper, or may be made of lightweight plastic for durability.

[0043] In addition, the present disclosure may be provided in the form of an application installed on a smart phone or pad. In this case, the integrated screen is presented to the patient in the form of a display, the patient can gaze at a divided display window including the intended alphabet or number on the screen, and the guardian ascertains the position of the pupil of the patient and touches the corresponding divided display window. In the divided display window, the corresponding detailed dial is stored in advance, and thus, the alphabet or number included in the selected detailed dial can be disposed on the screen at a predetermined angle based on the center of the screen. When the patient gazes at the intended alphabet or number through the movement of the pupil, the character appears on a lower end or a specific area of the screen as the conversation partner of the patient touches the corresponding alphabet or number. When a smart phone application is used, the gaze direction of the patient is recognized by a built-in camera, and the character intended by the patient can be displayed through the integrated dial and the detailed dial.

[0044] Subsequent processes may be performed in the same manner as described above, a word or a sentence by intended by the patient is expressed by combining the alphabets and numbers selected by the patient, and thus, the guardian may smoothly communicate with the patient.

[0045] Hereinbefore, the present disclosure is mainly described with respect to the preferred embodiment, but this is merely an example and does not limit the present disclosure, and a person skilled in the field to which the present disclosure belongs may find that various modifications and applications not illustrated above are possible without departing from the essential characteristics of the present disclosure. For example, each component specifically illustrated in the embodiment of the present disclosure can be implemented by modification. Moreover, differences related to these modifications and applications should be construed as being included in the scope of the present disclosure defined in the appended claims.

[0046] The English input keyboard for severe patients according to the embodiment of the present disclosure can be used for a patient who can move his/her eyes of physical movements of the patient, and the patient can quickly and accurately express an intention by staring at the eyes without using an expensive device.

[0047] The English input keyboard of the present disclosure can be provided in a state of being displayed on a screen on a portable smartphone or pad, and each screen may be provided with multiple English input keyboards. Accordingly, a method suitable for the patient is selected so that a pseudo expression is possible, and the pseudo expression is possible even when the patient moves.

[0048] The English input keyboard of the present disclosure can be used voluntarily or assisted by a conversation partner depending on physical ability of a user, and can be applied to a patient with cognitive abilities corresponding to a normal level and literacy.
