APPARATUS AND METHOD OF ASSISTING VISUALLY IMPAIRED PERSONS TO GENERATE GRAPHICAL DATA IN A COMPUTER

摘要

In order to assist a visually impaired person to generate digital image data in a computer, a plurality of graph components are provided each of which is tactually recognized by the visually impaired person. A touch graph is generated using the graph components on a plate-like member by the visually impaired person. The touch graph is acquired into a computer using an input interface such as a digital still camera. Subsequently, a computer software analyzing the digital image data s o as to define each of the graph components and logical relationship between the graph components. The analyzed digital image data is stored in a memory within the computer.
