Design Tactile Interfaces with Enhanced Depth Images With Patterns and Textures for Visually Impaired People

Abstract

This paper presents the design and development of Tactile Interfaces with Enhanced Images with Patterns and Textures for Visually Impaired People. In particular, haptic interfaces uses a number of predefine tactile texture and patterns to enhance the experience of the tactile feeling of images for visually impaired people. The open source OpenCv application is used to automatically change group of colours from depth images to tactile texture and patterns. The depth images are captured with the he?p of RGB-Depth cameras. The tactile images are then explored by visually impaired people with the use of haptic interfaces. The predefined textures and patterns are more easily distinguished than uniformly colors in depth images.
