Data processing system with a touch screen and a digitizing tablet, both integrated in an input device
First Claim
1. A data processing system comprising:
- an input device with a touch screen for inputting data into the system by activating an operative touch screen area thereof by a first stimulus comprising a presence and location of a touch,a digitizing tablet for inputting data into the system by activating the tablet by a second stimulus comprising a presence and location of a stylus near an operative tablet area thereof,the touch screen area and the tablet area being at least partially overlapping,the touch screen and the digitizing tablet being coupled to a data handling means for processing the data,the touch screen comprising;
a first sensing means to convert said first stimulus into a first signal for supply to the data handling means, said first sensing means comprising a first component operative to output said first signal in response to said first stimulus,the digitizing tablet comprising;
a second sensing means to convert said second stimulus into a second signal for supply to the data handling means, said second sensing means comprising a second component operative to output said second signal in response to said second stimulus,the first and second components being physically and functionally distinct from each other, andthe first and second signals being available in parallel.

Abstract
A data processing system includes a multipurpose data input device formed by a touch screen and a digitizing tablet integrated with one another, which are activatable independently of each other by proper stimuli. The touch screen and the digitizing tablet each comprise a respective sensing means to sense the proper stimuli. The respective sensing means comprise respective components for producing respective signals representative of the proper stimuli, the respective components being physically and functionally distinct from one another. The input device is integrated with a flat panel display in order to establish a visual feedback to the user or to present information pertaining to the entered data after processing. The flat panel display, touch screen and digitizing tablet take a variety of forms and a variety of techniques are utilized to determine which of the touch screen and digitizing tablet is activated at any time.
