The present study evaluated the performance of congenitally blind people at recognizing twodimensional picture by touch, after a 45 hour training. Totally blind individuals served as observers in a haptically recognition task, both, before and after being trained at naming twodimensional raised-line drawings. Statistical analysis showed a significant effect of training with planar configuration...

Introduction According to the World Health Organization, at present there are 45 million people blind, worldwide, and 135 million are visually disabled, and depend on family support or care on a daily basis. Annually about 1-2 million people become blind and cataract is a major cause of blindness accounting for more than 50 percent of blindness burden. Prevalence of cataract is higher in develo...

Not knowing how colors and shapes look like is a serious penalty and they have to live with it an entire life. It is known that the human brain adapts and compensates with greater capabilities for hearing and touch when vision is low or missing, that is why blind peo...

This paper describes the development and evaluation of a computer game for blind and visually impaired people using a new haptic audio virtual environment (HAVE). The GRAB HAVE consists of a new two-finger haptic interface and Haptic Geometric Modeller which enables people to locate and interact with 3D computer-generated objects using their sense of touch and audio feedback. A simple 3D search...

Blindness is a term to describe conditions of people who have visual impairments. When visually impaired do an activity outside, he usually needs stick help them move. This study aims develop tracking that enable family member find the location blind when they are outside their home and can travel. GPS (Global Positioning System) technology allows get signal for its coordinates. wants blind, se...
