Abstract:
1. A text display device for displaying a text on a display device and receiving an operation performed by an operator, the text display device comprising: a display control section configured to display, on the display device, a text containing a feature position preset in the text display device; an input section including an input device having a two dimensional input area to receive an operation performed by a finger of the operator, the input section being to detect a presence of a contact of the finger with the two dimensional input area of the input device, and being configured to detect a first pair of XY-coordinates of a finger position at which the finger is in contact with the two dimensional input area; a calculation section configured to, when a contact of the finger is detected by the input section, (i) associate the first pair of XY-coordinates detected by the input section with an emphasis display position that is highlighted in the text displayed on the display device, (ii) calculate a relative distance in the text between the emphasis display position and the feature position, (iii) calculate, based on the relative distance and the first pair of XY-coordinates, a second pair of coordinates representing a position in the two dimensional input area, corresponding to the feature position in the text, and (iv) calculating a tactile sensation presentation amount corresponding to the relative distance; and a tactile sensation presentation section disposed on a side, opposing a surface on which the finger is in contact, of the input device, the tactile sensation presentation section being formed with a plurality of dots and being configured to move in multiple stages by arbitrary heights, wherein the tactile sensation presentation section forms, upon calculation of the tactile sensation presentation amount by the calculation section, a protrusion or depression formed by a combination of a shape of the dots associated with the feature position and a height represented by the tactile sensation presentation amount, at the position of the second pair of XY-coordinates in the input device.
