Graphic Perception System for Visually Impaired Groups

Wearable Smart System for Visually Impaired People

In this paper, we present a wearable smart system to help visually impaired persons (VIPs) walk by themselves through the streets, navigate in public places, and seek assistance. The main components of the system are a microcontroller board, various sensors, cellular communication and GPS modules, and a solar panel. The system employs a set of sensors to track the path and alert the user of obs...

Sensor Based Assistance System for Visually Impaired

This paper is focussed to develop an electronic navigation system for visually impaired, that makes use of sensors for obstacle detection. People who are visually impaired struggle every day in performing actions that can be as simple as moving from one point to another without falling down or knocking against obstacles. An Electronic Travel Aid (ETA) is a form of assistive technology having th...

Coloresia: An Interactive Colour Perception Device for the Visually Impaired

A significative percentage of the human population suffer from impairments in their capacity to distinguish or even see colours. For them, everyday tasks like navigating through a train or metro network map becomes demanding. We present a novel technique for extracting colour information from everyday natural stimuli and presenting it to visually impaired users as pleasant, non-invasive sound. ...

HOWARD: High-Order Wavefront Aberration Regularized Deconvolution for Enhancing Graphic Displays for Visually Impaired Computer Users

High-Order Wavefront Aberration Regularized Deconvolution (HOWARD) is a complete closed loop system developed for simulating human visual function with the primary goal of enhancing graphic computer displays for users that have refractive errors (resulting in difficulty interacting with visual displays). Visual function is a primary requirement for a human being to engage in computer usage effi...
