Symbol Talker A is designed for somebody starting off with alternative communication. Words are organised by topic. On each topic grid you can build simple sentences from one or two selections.
Symbol Talker B
Symbol Talker B builds on the language and access skills that have been established and provides vocabulary to build sentences from up to three selections.
Symbol Talker C
Symbol Talker C provides a transition for people that have successfully communicated with a topic based vocabulary and are ready to use more language tools to say more. Core vocabulary is the name given to the words we speak most often. In Symbol Talker C you can access core vocabulary on each topic grid, giving you the power to create a much wider variety of sentences.
Symbol Talker D
Symbol Talker D promotes core vocabulary to the top page. This means you can generate novel sentences very quickly and you only need to visit topic pages to find less common words. The smart grammar tools in Grid 3 help you generate grammatically correct sentences with fewer selections.
Touch, with a finger or stylus, is one of the most familiar access methods. When using Grid 3 software, you can choose the touch method that works best for you to make accurate, easy, and timely selections for communication.
Gaze interaction gives you a way to make selections using just your eyes. An eye tracker tracks the movement and position of your eyes on the screen.
Use scanning as your access method when you have limited body movement or control and are not able to use other access methods.
Make selections using mouse click, mouse dwell, joystick, or head mouse
