Abstract:
Reading of text and understanding images by touch is an important alternative and additional source of information when sight is absent or lost. Tactile graphics and models such as edge maps, binary output, etc., are the solution for simple access to images for blind persons. This paper introduces an approach to model the human tactile system based on the responses produced by stimuli on microcapsule paper. This system is utilized for the purpose of generating optimum halftone patterns on microcapsule paper that can be utilized for the effective generation of tactile graphics.
