Read-Right is a therapy and research application accessed over the internet. It has been developed by UCL Institute of Neurology and UCL Multimedia. The project is funded by The Stroke Association. The aims of the project are twofold: 1) to provide a web-based therapy for patients with hemianopic alexia (HA); 2) to find out if the therapy works over the internet. To do this, we need to collect information from users to see if they are improving with practice.
