New iPad app for people with sight loss needs backing from publishers
Scientists from RoyalHollowayUniversity are launching a new iPad app to help people with macular disease, the most common cause of sight loss in the UK.
People affected by the condition, who include Dame Judi Dench and Last of the Summer Wine actor Peter Sallis, find it difficult to read normally, having lost their central vision. However, they can make use of their peripheral vision using a simple technique called eccentric viewing.
The new app, MD_evReader, is designed to enhance the eccentric viewing technique for reading eBooks. It enables users to scroll text from any ePub document in a single stream, like a news ’ticker’. The text is presented into the reader’s best point of eccentric vision and helps them to maintain a ‘steady eye’. The speed in which the text appears can be changed using a simple trackpad according to the reader’s needs. The app also allows users to make changes to background and text colour, and allows content to be displayed on digital television screens, enabling very large font sizes to be used.
However, the success of the app relies on the cooperation of publishers, who often use Digital Rights Management (DRM) systems to lock publications and prevent unauthorised copying. In effect these prevent the MD_evReader, and other accessibility software, from unlocking the publication and displaying content in the best way for users. This restricts the range of books that can be used with the app, to copyright free volumes and those whose publishers have relaxed their DRM systems.
Professor Robin Walker from the Department of Psychology at Royal Holloway said: “DRM is a major limitation. Of course we recognise the rights of manufacturers, authors and publishers to maintain their intellectual property, but we would urge them to consider using lightweight DRM systems which would allow the MD_evReader to be used.
“People with low vision caused by macular disease, experience extreme difficulty with everyday tasks such as reading, which severely affects their quality of life. Volunteers who have been involved in testing the app have largely reported that the experience of reading was greatly improved with this system.”
Helen Jackman, Chief Executive of the Macular Society, said: “This app represents an excellent opportunity to help people affected by macular disease to read more easily. However, for it to be able to reach its full potential we need publishers to stop using DRM in a way that compromises accessibility.
“Some publishers, including the Harry Potter books’ Pottermore, have stopped using DRM and reported no adverse commercial affect. We now need other publishers to follow suit so that those affected by sight loss have the same access to literature as everyone else.”

Notes to editors
1)Royal Holloway is one of the UK’s leading universities. We have a distinguished history of world-changing research and innovative teaching, with an international outlook. Our close-knit community enables students to benefit from a personalised experience, with staff collaborating across facilities to enhance health, science, culture and security on a global scale. Set in 135 acres of parkland in Surrey, our campus is recognised as one of the most beautiful in the world, and the pioneering spirit of our founders continues to inspire teaching and research today.
2)The Macular Society is the national charity for anyone affected by central vision loss. Our 15,000 members make us the biggest patient group in the sight loss sector and the voice of people with macular conditions. We provide free information and support to improve lives and ensure no one has to face macular disease alone. We have more than 250 Macular Society support group around the UK and beyond. We fund research so that one day we can overcome macular disease.
3)Macular disease causes a loss of central vision and is the most common form of sight loss in the UK, affecting more than 500,000 people. The macula is the central and most sensitive part of the retina. People with advanced macular disease cannot read, drive or recognise faces. Half of all people in the UK registered as sight impaired or severely sight impaired have macular disease. For information, advice or support concerning macular disease, contact the Macular Society’s helpline on 0300 3030 111 or email
