TOUCH SCREEN WITH USER INTERFACE ENHANCEMENT
First Claim
1. A computing system comprising:
- a body;
a central processor configured for running applications for the computing system; and
a touch screen integrated in the body, the touch screen comprising;
a display screen;
a touch sensor configured to sense user input over the display screen; and
a controller communicatively coupled to the central processor, the controller configured to;
operate in a first mode wherein the controller drives the touch sensor to sense the user input and provides information about the user input to the central processor for interacting with a software application running on the central processor; and
operate in a second mode wherein the controller provides a security interlock independently from the central processor.

Abstract
The present invention is a graphical user interface in a computing device having a processor running an operating system and a display. The graphical user interface comprises a touch screen and a driver coupling the touch screen to the operating system. The driver can display a plurality of icons on the touch screen, or a plurality of screen images having at least one icon, with each of the icons associated with operations on the display and/or the touch screen. Other embodiments include the touch screen having unactivated and activated states, as well as the presence of an application programming interface that enables an application to display at least one image on the touch screen.

11. A method of implementing a security interlock in a computing system comprising a body, a central processor configured for running applications for the computing system, and a touch screen integrated in the body, the method comprising:
-
operating the touch screen independently from the central processor to present an image associated with the security interlock; operating the touch screen independently from the central processor to sense user input for authenticating a user using the touch screen; operating the touch screen independent from the central processor to determine an authentication status of the user based on the user input; and allowing access to the central processor in response to a validation of the authentication status of the user. - View Dependent Claims (12, 13, 14)

15. A controller, the controller adapted to be coupled to a central processor in a computing system having a touch sensor and a display screen, the controller configured to:
-
operate in a first mode where the controller drives the touch sensor to sense user input over the display screen and provides information about the user input to the central processor for interacting with a software application running on the central processor; and operate in a second mode where the controller provides a security interlock independently from the central processor. - View Dependent Claims (16, 17, 18, 19, 20)
