Description

Braille and print integrated input device {BRAILLE AND LETTER INPUT DEVICE}

The present invention relates to a braille input device, and more particularly, to a three-dimensional input device capable of inputting both braille and ink characters.

Braille is a character for the visually impaired, and means a dot in the form of a certain point projected on the ground or a plane so that the blind, deaf or low vision blind can identify it. Recognize the meaning of letters and symbols embedded in touch or braille. In braille, characters, abbreviations and numbers agreed upon in advance may be respectively expressed using 4, 6 or 8 dots for braille.

Recently, with the development of computers and smart phones, the need for visually impaired people to work using these tools is increasing. In general, visually impaired people use braille terminals in which a Perkins braille keyboard and a braille display device are integrated as disclosed in Korean Patent Registration No. 10-1846526 in schools for the blind.

However, low vision blind people who do not know braille prefer to use a general PC QWERTY keyboard rather than a Perkins braille keyboard. Therefore, the existing braille terminals could be used by blind and visually impaired people who have learned Braille, but have limitations in that they cannot be used by blind people who use a general QWERTY keyboard or who have not yet learned Braille, such as low-vision blind people.

Therefore, there is an increasing need for a portable keyboard that can be commonly used by visually impaired people of various disability levels.

First connection terminal 102, second connection terminal 104, speaker unit 106, upper coupling groove 110, first braille key button unit 120, first rotation plate 125, second braille key The button unit 140, the second rotation plate 145, the braille function key button unit 160, the mute key button unit 170, and the lower coupling groove 180 have already been described with reference to FIGS. 1 to 5, so detailed descriptions are omitted. do.

The central processing unit 183 determines information input from the first braille key button unit 120, the second braille key button unit 140, and the braille function key button unit 160, and the main body unit 100 ) plays a role in controlling the overall operation of

The communication unit 184 serves to transmit information processing results of the central processing unit 183 to an external terminal.

The storage unit 185 serves to store data processed by the heavy-duty processing unit 183 and the like.

The sensor unit 190 is composed of one or more sensors and serves to measure a sensor value to be used for controlling the central processing unit 183.

In addition, although not shown in FIG. 6 , a power unit for supplying power to the operation of components of the body unit 100 may be disposed. The power unit may include both a terminal connected to an external power supply terminal and a battery unit capable of being charged.

Referring to FIG. 7 , the sensor unit 190 may include a gyro sensor 191 , an acceleration sensor 193 , a cover sensor 195 , and an illuminance sensor 197 .

The gyro sensor 191 is a sensor that measures angular velocity according to the movement of the main body 100 , and the acceleration sensor 193 is a sensor that measures acceleration according to the movement of the main body 100 . The central processing unit 183 may determine the movement of the main body 100 using the measured values of the gyro sensor 191 and the acceleration sensor 193 .

For example, the central processing unit 100 determines whether the braille key buttons 120 and 140 are disposed upward from the bottom surface of the main body 100 or whether the mute key button unit 170 is disposed upward or the braille function. It is possible to determine whether the key button unit 160 is disposed upward.

The cover sensor 195 refers to a sensor that detects whether or not the upper cover 200 and the lower cover 300 are coupled to the main body 100 . For example, when the upper cover coupling protrusion 200 and the lower cover coupling protrusion 320 of the upper cover 200 and the lower cover 300 are coupled to the upper coupling groove 100 or the lower coupling groove 180 It is determined that the cover is coupled by detecting the flow of current, and when the coupling is released, it is possible to determine that the cover is disconnected by detecting that the current is disconnected.

The illuminance sensor 197 may be installed on the upper and lower surfaces of the main body 100 to measure the illuminance. For example, when light is detected by the illuminance sensor 197, the central processing unit 183 may determine that the cover of the corresponding surface is disengaged.

That is, the central processing unit 183 determines whether the upper cover 200 and the lower cover 300 are coupled to the main body 100 by a combination of one or more of the above sensor values, and the upper cover ( 200) is disengaged, input of the braille key button portions 120 and 140 may be activated, and when the upper cover 300 is disengaged, input of the mute key button portion may be activated.

It is possible to automatically input and activate a button unit that a visually impaired person wants to use only with a movement operation.

In addition, the central processing unit 183 can improve the convenience of the visually impaired by interpreting the text input by the visually impaired and outputting it as voice through the speaker 106, and through the communication unit 184, communication methods such as Bluetooth It can be used to operate in conjunction with external terminals such as smart phones and notebook computers.

In addition, in the integrated input device 10 of the present invention, the braille key button parts 120 and 140 and the mute key button part 170 are disposed on the upper and lower surfaces of the body part 100, respectively, so that the user can see the time as a single device. It has the effect of responding to the various needs of people with disabilities.

In addition, the braille key button parts 120 and 140 of the integrated input device 10 are configured to be rotatable with respect to the main body 100 through the rotary plates 145 and 150, so that the rotary plate 145 and 150) has an effect of enabling customized key button arrangement.

At this time, in order to increase the usability of the braille key button parts 120 and 140, the rotating plates 145 and 150 are configured to have high rotational friction so that they can rotate only when a certain force or more is applied, or the user wants to fix them at a specific position. In this case, it may be configured to further include a rotation stop so that rotation is prohibited.
