The SL87 Lightwriter® is a compact integrated scanning communication
aid, with very high legibility. The keyboard permits users with
progressive conditions to migrate from direct selection to scanning at
their own pace, with no delays in reassessment, ordering, or supply.
When the SL87 is used in scanning mode, the keyboard allows faster
creation of user memories and change of setups by the therapist or
carer.
Please click on the black bar at the top of the demonstration to turn the sound on/off.
Scanning is a selection technique for people who cannot use a keyboard.
The alphabet is displayed on a screen on which a selector box moves automatically from letter to letter. When the selector box reaches the desired letter, the user presses a switch to select that letter.
