What is CVI?



This example follows on from the 3Z (Zoom In Zip Up Zoom Out) previous section, which explains the approach in detail.

Going to a playground may have proved confusing and frightening for many reasons. Even one at school like this one:

This is how the playground may look to someone with reduced visual attention - they don't see the blurry bit, that's just to illustrate how little visual attention they may have compared so someone without simultanagnosia.

This may be more like how they experience it.

In addition to the lack of visual attention, there may also be children running around, creating a perceived threat through looming.

Zoom in

Teach the person how to use one single section. It's a slide, how to get on it, how to go down it. Repeat until it is known, then teach about another section.

Zoom in

And learn about this section, the green ladder that goes from the floor, and the grey steps that go up and down. When brave enough, the yellow pole you can slide down.

Zip them together and zoom out

Keep zooming in, learning a single section, then zipping it together with the ever increasing known 'whole' and eventually you will have an understanding of the school playground.

Mary, who has simultanagnostic vision, commented:

It sounds strange to relate it to this, but I can see this concept would have helped with going to Disneyworld last year (I realise this is a massive scale). But if we had focused on specific areas, zoomed in and taken the time to explore that particular area and become familiar with it, before heading to another area - it wouldn't have been so overwhelming.
