CVI - SIM

Intangible Heritage

We create computer simulations so you can see the world as it might be seen by those with brain-based impairments of vision, called cerebral visual impairment or CVI. CVI-SIM is a collaboration between the Schools of Medicine and Computer Science. We support many student projects. Our project partner is the charity CVI Scotland. The programme has been created through listening to people with CVI and consulting with CVI experts. We know CVI is a very complex medical condition. Our simulations serve many purposes. Most important is to help with understanding, to improve support for people affected by CVI. CVI-SIM has also proved to be an effective platform for research, and through listening to people with CVI, we are learning more and more about the condition. Our simulations include visual perception difficulties that affect many children.

Cerebral Visual Impairment (CVI) Virtual Reality Simulations made in Unreal Engine 5.

The way we have developed this preliminary simulation has been to listen in detail to the described visual experiences of adults with CVI who have been diagnosed with dorsal stream dysfunction, including simultanagnostic vision. Initially, we took videos inside a shop to show the visual complexity of this exercise. We then asked volunteer adults with dorsal stream dysfunction to give an auditory account of what they were able to see. We simulated their verbal description, and asked them to view these simulations and to let us know how realistic they were. The results were fascinating. We used this information to come up with our next simulation called the Dorsal Stream Dysfunction CVI Experience. This was viewed by several adults with validated marked dorsal stream dysfunction, who explained that when they compared the simulated version of this video with the version that was not simulated, the experience was very similar.
