Direct select mode also makes use of the tunable tap/touch. This feature accommodates those who can touch a device but whose abilities don’t support a quick touch and release (e.g. a “tap”). You get to the touch configuration screen from the Tap/Touch Configuration toolbar button:
Use the Tap setting to require a touch and release in order to play a message. You can vary the tap dwell time from 0.1 to 5.0 seconds and touch drift amount from 10% to 200% of the button’s size. Use the Touch setting to only require a touch on a button to play a message. Dwell and drift settings don’t affect the Touch setting.
Failed Tap/Touch Feedback – enables/disables a “bloop” sound when a tap exceeds the tap dwell or drift settings.
Button Click Feedback – enables/disables a “click” sound when a tap/touch is initiated.
Play Message from Button Only – When enabled, a tap/touch will only be detected within the boundaries of the button image. When disabled, the entire iPad/button player surface can activate a message. For example, when this switch is enabled and you zoom out on a button (pinch in to make smaller), you can encourage greater motor skill control.
