1. A method of controlling a tactile interface device implemented by a computing device including a processor, and connected to the computing device to interact with a user, the method comprising:
generating information inputted to an application configured to be executed in the computing device based on an input at the tactile interface device including a tactile display;
selecting a focus area of a display screen of the computing device, based on outputs from the application, and identifying input coordinates within the selected focus area;
generating first output information configured to be transmitted to the tactile interface device, based on the selected focus area and the identified input coordinates, wherein
the output information comprises data for implementing a tactile graphic formed of a plurality of two-dimensional tactile pixels,
the tactile display includes a first layer and a second layer,
the first layer includes a tactile icon for executing an instruction to change a displayed image in the focus area of the display screen of the computing device,
the second layer includes text information in a form of Braille, the text information is information of a tactile graphic element corresponding to the input coordinates,
the input coordinates are changed in response to the input at the tactile interface device, and
the text information of the second layer is automatically changed in response to a change of the input coordinates, to be information of another tactile graphic element corresponding to changed input coordinates; and
generating second output information configured to be transmitted to the tactile interface device, the second output information controls the tactile interface device to perform, while the input coordinates correspond to a location of the tactile graphic element, a periodical movement of at least one tactile pixel of the tactile graphic element corresponding to the input coordinates.
