Abstract
The present invention relates to a method of generating sounds by a graphical user interface (GUI) used on information processing apparatuses and computers and, more particularly, to a method of acoustically expressing image information to enable visually disabled people having difficulty in using GUI to operate apparatuses with GUI, and an apparatus for carrying out the method. A specific sound is assigned before hand to an object displayed in a drawing space on a display screen or the like, and the object is expressed acoustically by generating the sound by a sound generating device for a period of time corresponding to the length of the outline of the object, the travel of the object or the ratio of change in size of the object.
