This section explains how to change button timing and how to hide and display button navigation arrows.
Button Timing
To accommodate motor control difficulties, you can set buttons to activate on touch or release, set dwell time, and set release time. Select Menu > Settings and scroll to the Buttons section.
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. Select the Activate on Release toggle button to turn the setting ON/OFF.
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, select 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.
Show/Hide Button Navigation Arrows
Buttons that navigate to new pages display a small arrow in the top right corner.
To show/hide all navigation arrows:
Select Menu > Settings and scroll to the Navigation section.
Toggle ON/OFF Button Navigation Icons.
