Activate on Release
When this setting is turned on, buttons are activated when released rather than when touched. This
allows the device user to slide his or her finger across the screen before finally releasing on the button
that he or she wants to select. To turn the setting on or off, tap the Activate on Release toggle switch.
Dwell Time
The dwell time setting controls the delay before a button press is recognized. When the user touches a
button, a slight dimming and a white square box identifies the chosen button. As long as the user
continues to keep his or her finger inside the button area the dwell timer counts down. Once the time is
reached, the button press is accepted. To set a dwell time, tap
Dwell Time
and select a value from 0.1
Seconds to 5.0 Seconds.
Release Time
Release time applies to buttons and to the SDB.
Buttons:
Release time is intended to help prevent accidental double button activations. When the time
is set, all buttons are disabled for the specified period of time after a button is activated.
SDB:
Release time is intended to prevent accidental speaking of words displayed in the SDB twice. When
the time is set, the SDB is disabled for the specified period of time after the user taps the SDB to speak
the words displayed. The Release Time setting does not affect the SDB Clear button (
X
).
To set a release time, tap
Release Time
and select a value from 0.1 Seconds to 5.0 Seconds.
