Touchpad enabled with ZIG ZAG Gesture

Touchpad Enable (Zig-Zag)

Users may place one finger down anywhere on the touchpad surface and quickly swipe back and forth with at least 4 detected direction changes in quick succession to re-enable a touchpad that has been disabled via a keyboard hotkey, enable/disable button, or through software controls.  See figure 12.  The touchpad will be re-enabled when a user swipes a single finger back and forth on the touchpad surface with 4 detected direction changes in quick succession.  The Zig-Zag gesture shall not be used to re-enable a touchpad that is disabled due to a user enabling the Disable Touchpad when USB mouse present option. 

Figure 12: Zig-zag Gesture Definition

Once triggered, the zig-zag gesture shall:

·         Re-enable the touchpad before finger lift off so the user can see the pointer movement.

·         Trigger the touchpad enable pop-up message from the notification area on the desktop.

·         Not change the user settings for USB mouse detection.  If the user has selected to disable the touchpad on USB mouse detection, then the touchpad will only be re-enabled for the current session.  Once the system is shutdown and restarted, the touchpad will continue to disable on USB mouse detection.
