1. A screen peripheral system, comprising:
- a computing device for providing a main image; and
a touch-activated input device for generating and displaying a composite image visible to a user of the screen peripheral system, the touch-activated input device comprising a plurality of pixels, the composite image simultaneously including;
a representation of at least one key, the representation of at least one key activating an input function; and
the main image provided by the computing device, the representation of at least one key being laid over the main image;
wherein the screen peripheral system implements variable-pixel control to form the representation of at least one key and to form the main image, the variable-pixel control causing pixels selected to form the representation of at least one key in the composite image to depend on and be activated simultaneously with pixels selected to form the main image, such that the main image and the representation of at least one key are displayed simultaneously to form the composite image;
further wherein the variable-pixel control includes logical operators to provide different blending/merging effects such that individual pixels of the touch-activated input device can be dedicated simultaneously to both the main image and the representation of at least one key.

Abstract
A screen peripheral system according to an embodiment of the invention includes a computing device for producing a main image and a touch-activated input device for generating and displaying a composite image visible to a user. The composite image simultaneously includes a representation of at least one key, for example a QWERTY keyboard, for activating an input function, and the main image provided by the computing device. The keyboard representation preferably is laid over the main image. According to one embodiment, the main image is an output image generated by an application being executed by the computing device. Other touch screen systems and methods are also disclosed.

19. A method of superimposing a representation of at least one key over a main image provided by a computing device, the method comprising:
-
(a) using variable-pixel control to form a representation of at least one key, the representation of at least one key activating an input function, and to form the main image, the variable-pixel control causing pixels selected to form the representation of at least one key to be activated simultaneously with pixels selected to form the main image; and (b) generating and displaying a composite image visible to a user of the screen peripheral system, the composite image simultaneously including the representation of at least one key and the main image produced by the computing device, the representation of at least one key being superimposed on the main image; wherein the variable-pixel control allows individual pixels to be dedicated simultaneously to both the main image and the representation of at least one key. - View Dependent Claims (20, 21, 22, 23, 24, 25)

26. A screen peripheral system, comprising:
-
means for computing, the means for computing providing a main image; means for displaying a composite image visible to a user of the screen peripheral system, the means for displaying also being for input to the means for computing, wherein the means for displaying comprises a plurality of pixels, the composite image simultaneously including; a representation of at least one input zone, the representation of at least one input zone activating an input function; and the main image provided by the means for computing, the representation of at least one input zone being laid over the main image; wherein pixels selected to form the representation of at least one input zone are activated simultaneously with pixels selected to form the main image, such that the main image and the representation of at least one input zone are displayed simultaneously to form the composite image; further wherein individual pixels of the means for displaying can be dedicated simultaneously to both the main image and the representation of at least one input zone. - View Dependent Claims (27, 28, 29, 30)
