The iPad app we’ve developed for Royal Holloway University is now in the app store. The MD evReader helps people with macular disease (MD) to read eBooks using the eccentric viewing technique. Eccentric viewing involves a person trying to see by making use of the peripheral, rather than central vision. The technique is like trying to see ‘out of the corner of your eye’ and can be a useful way of enhancing visual tasks such as reading. The app scrolls text, one line at a time, with the speed and direction of scrolling controlled by a track pad on the iPad screen. Large fonts can be used and the text can be presented onto a digital TV screen via HDMI.
Development required overcoming a number of technical challenges to ensure steady performance while rendering large fonts to two screens simultaneously.
