Who is the target user of Snap + Core First

Emerging communicators are well-suited for this communication software—specifically those with physical access issues. The flexibility to adapt grid sizes allows emerging communicators to start with just one large button while learning to use eye gaze or switch scanning.

Snap + Core First may also be suitable for students using touch access who are developing generative language by learning core vocabulary and require a small number of locations per page due to impaired motor ability.

What devices is it available on?

iOS devices (e.g. iPad) and Windows OS (e.g. Surface Pro).

What alternative access methods is it compatible with?

iOS: touch access and switch scanning via the Pretorian APPlicator switch interface (I have not had success using other switch interfaces).

Windows OS: touch access, eye gaze, mouse emulation (e.g. joystick) and switch scanning via the EyeMobile Plus switch interface.

**Note: I do not recommend using Snap + Core First for auditory linear switch scanning because you cannot edit the scanning pattern.

What grid sizes is it available in?


What symbol set does it use?

PCS symbols

What voices does it use?

Acapela Voices
