Figure drawing apparatus, figure drawing method and recording medium on which figure drawing programs are recorded

摘要

When a user touches positions on a touch panel display unit which correspond to a plurality of characteristic points of a user's desired figure, the user moves the touched positions in accordance with a shape of the figure and leaves his or her touches from the touched positions and touches an additional touch position, characteristic conditions of different figures (a circle, parallel lines, an equilateral triangle, a triangle, a square, a rectangle, a quadrangle, a straight line, a concentric circle, an ellipse, etc.) are determined in accordance with the touched positions, a locus of the movement of the touched positions and the additional touch position and a type of the figure and a drawing-position thereof are determined.

1. A figure drawing apparatus comprising:
a touch panel; a display unit; a touch position detection unit which detects (i) a single touch position, (ii) a plurality of touch positions simultaneously, and (iii) a movement of at least one of the touch positions detected in accordance with a user's touch operation of the touch panel; a drawing figure determination unit which, when the touch position detection unit detects a plurality of touch positions simultaneously, determines a type of a figure and a drawing-position of the figure in accordance with the touch positions detected simultaneously and a following movement of the touch positions detected by the touch position detection unit, or the touch positions detected simultaneously and a new touch position other than the touch positions detected by the touch position detection unit; a figure display control unit which displays a figure on the display unit in accordance with the type of the figure and the drawing-position of the figure determined by the drawing figure determination unit; a one-point locus display control unit which, when the touch position detection unit detects the single touch position and then the movement of the single touch position, displays a locus of the movement of the single touch position on the display unit; a locus moving unit which selects and moves a locus of the movement of the touch position displayed on the display unit by the one-point locus display control unit; and a symbol registration unit which, when the locus of the movement of the touch position is moved into a predetermined range near a characteristic point of the drawing by the locus moving unit and is released from being selected within the predetermined range, registers the locus of the movement of the touch position as a symbol indicating the characteristic point of the drawing, and arranges the locus of the movement of the touch position in a position suitable as the symbol indicating the characteristic point of the drawing.
