Method to enter System Function Mode without interfering with active application

   Disclosed is a method to bring up a "system function" screen on a touch display when neither a keyboard or any additional buttons are attached to the system. The method must work with any running application without interfering with the function of the application . Additionally, some environments (i.e. Point-of-Sale or Kiosk) require that the typical user should not be allowed switch away from the full screen application .

   This method requires that the touch driver and/or operating system monitor all touch sequences looking for a special sequence indicating that the user wishes to switch to the "system function" screen. The touch sequence implemented was a continuous touch of the display screen in a configured corner for a configured period of time. The default was a continuous touch in the lower left corner for 3 seconds. When the driver detects a touch that could be the beginning of the special touch sequence it buffers the touch input until the special touch sequence is complete or is determined to be different from the special touch sequence. If the special touch sequence is completed then the "system function" screen is displayed. If the special touch sequence is not completed then the buffered touch input is sent on to the application.

   This invention allows knowledgeable users (i.e. service personnel, store managers) to access systems functions without interfering with the app...
