Text display device, text display program, and text display method presenting tactile sensations in accordance with displayed text

摘要

The text display device includes: a display control section that displays, on a display device, a text containing a predetermined feature position; an input section that receives an operation performed by a finger of the operator on an input device, and detects a presence of a contact with the finger and XY-coordinates corresponding to a finger position; a calculation section that, when a contact with the finger is detected, associates the detected XY-coordinates with an emphasis display position in the displayed text, calculates a relative distance between the emphasis display position and the feature position, and calculates coordinate values corresponding to the feature position based on the relative distance and the detected XY-coordinates; and a tactile sensation presentation section that provides the operator with a tactile sensation of a protrusion or a depression at a position in the input area indicated by the calculated coordinate values.

主权项

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.
