Dynamic Screen VOCAs

Dynamic screen devices display symbols or graphics on the screen rather than on paper sheets. The device can store multiple ‘pages’ and the user can navigate between them by selecting an appropriate key on the screen.

There is great variety in the way the device can be set up. For example, there may be a choice of between one and 72 ‘keys’ per page, pages can be linked together in simple or multi-branching ways, or may automatically open/ close when a particular vocabulary item is selected.

On the dynamic screen devices illustrated below the user can change the page that is displayed. The pages may be any combination of symbols pictures, words and phrases. They are therefore equally suitable for those who are highly literate and for those without reading and spelling skills. Some offer additional features such as SMS, playing music, viewing photographs, Skype, internet access and email. They run on internal batteries that need to be charged overnight every night in order that they can be used for the whole of the next day.

Dedicated communication devices with dynamic displays cost several thousand pounds.

While careful assessment of skills and needs is required before purchasing any equipment, an assessment is imperative for equipment that is more complex than digitised VOCAs with paper displays.
