FIGURE 7-8 Martin using his eye-gaze system to communicate and access his environment�
FIGURE 7-9 Laminated alphabet chart with blank cells to write important messages that Martin requires to access
on a daily basis�
Martin used his iPad for a while; however, due to his physical deterioration he is no
longer able to do so.
Low-Tech
Alternatives were discussed in situations when using the eye gaze was not suitable, such as in
the middle of the night or in the shower. A laminated alphabet chart (Fig. 7-9) was issued to
be used with partner-assisted scanning. In Martin’s case the conversation partner points to
each row and Martin indicates yes when they reach the row that contains the letter he wants.
The conversation partner repeats the process in that row until they reach the letter he wants.
The process is repeated until a word or a message is composed and Martin is understood.
The alphabet chart can also be customised to add everyday phrases to further speed up
communication when the request may be urgent.
