Assistive Examination System for Visually Impaired

An Efficient Assistive System for the Visually Impaired

This paper presents an assistive system for the visually impaired that helps the individual to move about in the environment freely and avoids obstacles in the process. This small and efficient obstacle detection system (ODS) is placed on the shoes of the visually challenged person to provide free mobility for the individual. The system contains a microcontroller ARM cortex M3 LPC1768 which rec...

Mobile assistive technologies for the visually impaired.

There are around 285 million visually impaired people worldwide, and around 370,000 people are registered as blind or partially sighted in the UK. Ongoing advances in information technology (IT) are increasing the scope for IT-based mobile assistive technologies to facilitate the independence, safety, and improved quality of life of the visually impaired. Research is being directed at making mo...

Smart Cane: Assistive Cane for Visually-impaired People

This paper reports on a study that helps visually-impaired people to walk more confidently. The study hypothesizes that a smart cane that alerts visually-impaired people over obstacles in front could help them in walking with less accident. The aim of the paper is to address the development work of a cane that could communicate with the users through voice alert and vibration, which is named Sm...

A Raspberry Pi Based Assistive Aid for Visually Impaired Users

According to who fact sheet of 2013, 39 million people are blind and 246 million have low vision. With 82% of blind population being 50 years old or above, there are many who have lived majority of their lives with an inability to do tasks like read, write or walk without help. This paper describes the implementation of Raspberry based assistive aid for visually impaired users using speeded up ...
