Description

[0001] Tactile Interfacing Device and Tactile Interfacing Method [

The present invention relates to a tactile interface device and a tactile interface method. More particularly, the present invention relates to a tactile interface device and a tactile interface method that enable a visually impaired person to interact with a computer more intuitively and efficiently To a tactile interface device and a tactile interface method.

In the information society, it is essential to acquire and use information using computers, and this tendency is the same for the general public as well as the visually impaired.

In order to improve the level of informatization of the visually impaired, they should also be able to acquire and use information at a level similar to that of the normal person. This is important because it makes the daily life of the visually impaired more convenient, Do. In addition, it is very important because it can ultimately improve the welfare of the visually impaired by providing various educational opportunities and expanding opportunities for social advancement and participation.

However, the conventional method of using the present computer mainly uses a method of visually recognizing visual information output through a monitor and inputting information using an input tool such as a keyboard, a mouse, or a touch pad. Therefore, there is a great limitation in visually impaired persons who can not use the time to perceive the output information of the computer at the same level as the general person and to interact such as immediate information input. As a result, the visual impairment significantly degrades the efficiency of computer use, thereby greatly depriving the computer of opportunities for information acquisition and utilization.

Various techniques have been developed to recognize the visual information and to interact with the computer through the use of the hearing, tactile sense, etc., in order to solve the difficulties in using the computer of the visually impaired. As a representative technology, there is a screen reader which assists the visually impaired to use the computer through the hearing. This is a device or software that helps users to use the computer by outputting the contents displayed on the computer screen and the keyboard information inputted by the user.

However, the screen reader has difficulty in finding the screen output information because it searches Graphic User Interface (GUI) elements of the output screen by only one line of linearized information without two-dimensional spatial position information on the output screen. Especially, The more information there is, the greater the difficulty. In addition, since screen readers provide only a simple textual explanatory description for various graphic information such as pictures and diagrams in addition to characters and GUI elements, the visually impaired can understand and interact with graphic information It will have great difficulty.

Another related art is a Braille information terminal which transmits character information through a braille cell by a tactile sense. This is a method that is used as an independent device by providing some functions of a computer useful for a visually impaired person and a method of using as a screen output auxiliary device for outputting text information of a computer screen analyzed by a screen reader in braille. Instead of acting as an interface for efficient interaction with a computer, both of them serve as substitutes for a computer to perform only a limited number of functions of the computer or as an output aid for outputting textual information in braille . Particularly, the Braille information terminal specialized in the output of braille has a problem that it can not display the graphic information like the screen reader.
