<p>PURPOSE:To indicate other part of a lattice intersection with high accuracy and quickly by generating coordinate position information of a mouse cursor from information of a mouse cursor position and information of a key input, and also, generating coordinate position information of the nearest lattice intersection to its coordinate position, based on lattice information. CONSTITUTION:From information of a key input inputted by a key information input part 13 and converted to a numerical value and information of the present mouse cursor position read by a mouse cursor coordinate position reading part 11, a new mouse cursor coordinate position is generated by a first mouse cursor coordinate generating part 14. Subsequently, by a second mouse cursor coordinate reading part 16, coordinate position information of the nearest lattice intersection to the new mouse cursor coordinate position is generated, based on lattice information obtained from a lattice information managing part 15, and displayed on a display 17. In such a way, the alignment of the mouse cursor with a target lattice intersection can be executed exactly and simply.</p> |
