VIZIYON: Assistive handheld device for visually challenged

Portable Camera Based Assistive Pattern Recognition for Visually Challenged Persons

Choosing clothes, food recognition and traffic signal analysis are major challenges for visually impaired persons. The existing automatic clothing pattern recognition is also a challenging research problem due to rotation, scaling, illumination, and especially large intra class pattern variations. This project, a camera based assistive framework is proposed to help blind persons for identificat...

A Handheld Colour-to-Speech Device for the Visually Impaired

A hardware device is presented that converts colour to speech for use by the blind and visually impaired. The use of audio tones for transferring knowledge of colours identified to individuals was investigated but was discarded in favour of the use of direct speech. A unique colourclustering algorithm was implemented using a hardware description language (VHDL), which inturn was used to program...

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...

Assistive Computer Interface for Visually Impaired Persons

Survey On Computer Vision Based Assistive Device For The Blind And Visually Impaired

The blind and visually impaired people needs assistance in their day-to-day life, for navigation, detecting objects, text recognition etc., Computer vision based assistive device for the blind is promising and efficient technology but still, the area is still a developing one. Various assistive device exist today to assist the blind most of which are still in prototypical stages. Purpose of thi...
