This section considers the actual physical area of visual attention a person with simultanagnostic vision can give, as far as it can be understood.
One way we have tried to understand more about this area is to ask people if there is a preference for viewing screen size, whether it be a huge television screen or a little smartphone screen.
Below are some of the accounts we have heard from people with simultanagnostic vision:
Being able to approximate the physical size of what needs to be looked at to the size of the field of visual attention, while at the same time not going smaller than what can be seen, is a very useful idea, because instructions can be given to ensure everything is the best size. When things are bigger, then the person with simultanagnostic vision may only be able to see a part of it, but when they are smaller again the information may be too small to see.
What's needed is the happy medium.
Consider simultanagnostic vision to be like a lighthouse with a single narrow beam of vision shining through a dense fog. Only what the beam shines upon is visible to the person, and the size of that beam will vary from person to person. Nigel's beam is extremely narrow, whereas Connor's beam, is a little larger, but still considerably smaller than the full beam of a person without simultanagnostic vision.
However, there is a little twist to limited area of visual awareness, because the person does not know they have it. As far as they are concerned, what they see is all there is to see.
With repeated visits, Connor over time will learn to recognise it, probably aided by other triggers including the sounds, smells and routine. Some with simultanagnostic vision can do this more quickly and effectively than others.
Children with profound disabilities and simultanagnostic vision may find recognising, and becoming familiar with new places very challenging. However strategies to help them learn to recognise their environment and over time put together a fuller picture can be helpful, including as part of the routine, having fixed points that are repeated in the same order each week. This may include a person you always speak to, something you always touch (which becomes an 'object of reference'), and a song you sing at a certain point.
In profoundly disabled people, a Limited Area of Visual Attention may come across, in addition to the above as:
