Q

Some AAC systems support access options and others don’t.

What about keyguards?

A

?

17
Q

Direct Selection Activations Strategies

A

Timed activation – dwell time

Release activation – maintain direct contact

Filtered or averaged activation

18
Q

Scanning Patterns

A

Circular scanning – least complicated

Linear scanning – passes over every option

Group-item scanning – ex. Row-column scanning (can make own groups)

19
Q

1 reason for choosing scanning over direct selection?

A

being unable to physically do direct selection

physical abilities/ disabilities

20
Q

Consider…

A

scanning timing and speed

21
Q

Selection Control techniques

A
  1. Directed (inverse) scanning
  2. Automatic (regular or interrupted scanning)
  3. Step scanning
22
Q
  1. Directed (inverse) scanning
  2. Automatic (regular or interrupted scanning)
  3. Step scanning
A

activate switch until desired selection then quit activation

activate switch to start scanning then activate switch to stop scanning

only moves through selections if switch is activated, then either pause or use another switch to choose selection

23
Q

Feedback
