Smart Cane: A Low Cost Assistive Device for the Visually Impaired

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...

Drishti: An Ultra-Low Cost Visual-Aural Assistive Technology for the Visually Impaired

We describe a Visual-Aural aid to support the visually impaired by providing them with aural feedback in form of natural speech representing their visual environment in a relatively inexpensive way. The scene is captured by an ordinary webcam and we use methods to detect, recognize and track objects, faces and text in 2D images and translate them into speech which the visually impaired individu...

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

Assistive Navigation Device for Visually Impaired—A Study on Reaction Time to Tactile Modality Stimuli

A tactile system to support severe visually-impaired or blind people in the world for their orientation and navigation had been developed. To optimize the design, some parameters of tactile display device were evaluated. In the present paper, we focused on the reaction time to tactile stimuli. In the test, the stimuli were produced through a vibration belt that was worn around the participants’...
