A new browser-based video game called Eyelander aims to promote compensatory strategies of functional vision in young people with cerebral visual impairment.
In the quest to help children with visual field loss caused by cerebral visual impairment, researchers in the United Kingdom have designed the game Eyelander.
The game uses the same concepts applied in adult stroke patients with hemianopia, said Jonathan Waddington, PhD, a computational neuroscientist for WESC Foundation in Exeter, United Kingdom. WESC Foundation is a specialist school for visually impaired children.
“We wanted to investigate whether these training programs could benefit children and young people,” said Dr. Waddington, who designed the game along with Timothy Hodgson, professor of cognitive neuroscience, School of Psychology, University of Lincoln, Lincoln, UK.
The game was developed by the University of Lincoln and WESC Foundation. The game developers knew they had to design something that would be more engaging for young users. They point out that existing training programs often are in black and white and have limited interaction.
“The aim of the game is to offer a colorful, engaging ‘training’ through playing the computer game—an activity which is often not viable for children with functional vision problems because of complications viewing screen graphics,” according to a statement from the University of Lincoln.
Users must find the correct shape of a certain color among a range of competing colors and shapes; the shapes are in different positions on the screen and are led by an animated avatar. One example: Players must find the orange circle that is not flashing on a screen that shows several green squares and one orange circle, all against a black background. Players receive verbal encouragement as they select the correct shape.
Game developers worked with students who have visual impairments and therapists at WESC to develop a training program that would maximize accessibility and engagement.
“The core principles of visual search training are still evident when playing Eyelander, but they are couched in game elements such as progress mechanics, simple aesthetics, narrative, and music,” Dr. Waddington said.
Users of Eyelander (available at eyelander.co.uk) are younger people with hemianopia as well as other forms of visual field loss caused by brain injury and brain dysfunction, Dr. Waddington said.
“It is too early to say whether Eyelander could be helpful for people with other visual impairments, but investigations in this area are ongoing,” he said.
The statement estimates that there are 25,800 blind and partially-sighted children in the U.K. and that cerebral visual impairment is the most common cause of blindness and visual impairment in the U.K. and other developed countries.
