Nystagmus Oscillopsia Simulator Virtual Reality

David Randall a researcher in the Medical Physics Group in the Department of Infection, Immunity & Cardiovascular Disease has developed and released a virtual reality smartphone app simulating nystagmus. Nystagmus is a condition where the eyes move involuntarily. Most people with nystagmus adapt to their involuntary eye movements but a significant number do not and must contend with the world constantly moving around them. The symptom of the world moving is called oscillopsia.

The project was conceived at a nystagmus awareness event, "Wobbly Wednesday" in November 2015 where David Randall and Dr John Fenner (Senior Lecturer in Department of Infection, Immunity & Cardiovascular Disease) met Dr Helen Griffiths (Senior Lecturer in Department of Oncology & Metabolism) from Orthoptics. Within 2 months, a collaboration between Medical Physics and Orthoptics resulted in a successful 6-month Insigneo Bursary application to produce a virtual reality smartphone app to simulate oscillopsia. The app uses eye movement recordings from real patients with nystagmus and replicates the eye movements within virtual reality. The app allows the user to gain an appreciation of what it is like to have oscillopsia.

The app was funded by Sheffield Hospitals Charity and if you would like to make a donation to support this research and the charity please do so here: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=DFU6BUYY2SF64

The app must be used in conjunction with a Google Cardboard device purchasable from many outlets. Below are two links to two cheap options Google Cardboard headsets on Amazon (we recommend you purchase a headset with a physical button – not NFC button).
