Peripheral Letter Charts Program
The Peripheral Letter Charts Program Group consists of two therapy programs: Sequence and Match.
Sequence Program
A chart displaying different size letters will appear on the display screen. The peripheral letter chart will
have the letter "E" as the central focus point. The client will need to locate and touch the letters in the
chart in alphabetical order.
Match Program
A chart displaying different size letters will appear on the display screen. In the center of the chart, a
letter will appear as the central focus point and will change periodically. The client will need to focus on
the center letter, locate, and touch the matching letter in the display chart before it changes. If the correct
letter is touched the center letter will change to a new letter for the client to match. If the correct letter is
not touched within the time set in the Center Active Delay Parameter, then the center letter will change
automatically, and the program will count it as an incorrect response.
