Title:
HAPTIC DISPLAY-BASED SYSTEM AND METHOD FOR DISPLAYING VISUAL INFORMATION FOR VISUALLY IMPAIRED PERSONS
Document Type and Number:
WIPO Patent Application WO/2014/014175
Kind Code:
A1
Abstract:
The present invention relates to a haptic display-based system and method for displaying visual information for visually impaired persons, which change educational documents including visual documents into tactile information and provide the tactile information together with characters. To this end, the present invention includes the steps of: extracting a character region and an image region for each piece of information mixed in the general education document; converting image information into tactile information according to complexity by analyzing the extracted image regions for division into a low-complexity image and a high-complexity image, and processing each image according to complexity for conversion into tactile information; and recognizing character information in the tactile character region and character information in the tactile image region and converting same into Braille information. Accordingly, visually impaired persons can be given various opportunities to use special documents, and the large number of resources required in the generation of sensory material can be reduced.
