Computer Entertainment Technologies for the Visually Impaired: An Overview

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...

Open source technologies for visually impaired people

We describe two open source applications which we have experienced as very useful aids for the integration of people suffering from visual impairments, from hypovision to actual blindness. The first application is based on speech synthesis and has been experienced by disabled university students. The second experience is oriented to schoolchildren with low residual vision, and it provides their...

Virtual computer monitor for visually-impaired users

Conventional computer display products for the visually impaired are limited by the amount of enlarged imagery that can be displayed at any one time, and by awkward methods for navigating about the scene. This paper describes a prototype system designed to address these problems by providing a head-mounted display interface which allows the user to position a cursor anywhere on an enlarged virt...

Authentication Technologies for the Blind or Visually Impaired

Current research on “Usable Security” is still in its infancy and usable security solutions are often designed without paying attention to human disabilities. This paper aims to help fill this void in the realm of blind computer users. More specifically, we discuss research challenges we are faced with and the directions we can take towards developing authentication technologies suitable for th...
