Abstract

In a pen-input computer or the like, it is impossible to distinguish an input method and to execute a proper process according to the input method. A touch panel driver generates finger-input coordinate values for a display screen. A digitizer driver generates pen-input coordinate values for the display screen. A processor receives the coordinate values and additional information indicative of either the finger-input or the pen-input from a source discriminator, starts an inputting process according to the input method, and allows a virtual keyboard to be displayed onto the screen or allows a “CHR input pad” window to be opened.

Claims

1. An information processing apparatus comprising:

first coordinate input means;

second coordinate input means;

selecting means for selecting an input type by determining whether an input was made by one of said first coordinate input means and said second coordinate input means or by both of said first coordinate input means and said second coordinate input means; and

drawing means for determining a drawing attribute on the basis of the input type selected by said selecting means and drawing a line according to the determined drawing attribute.

2. An information processing apparatus according to claim 1, further comprising discriminating means for discriminating whether a coordinate value input by said first coordinate input means and/or said second coordinate input means exists inside a predetermined region of an input area.

3. An information processing apparatus according to claim 1, wherein said first coordinate input means is comprised of a pen input and said second coordinate input means is comprised of a touch panel.

4. An information processing apparatus according to claim 3, wherein said first coordinate input means and said second coordinate input means detect input coordinates by different methods.

5. An information processing apparatus according to claim 4, wherein said second coordinate input means detects the input coordinates by a change in resistance value.

6. An information processing apparatus according to claim 4, wherein said first coordinate input means detects the input coordinates by a transmission time of an acoustic wave.

7. An information processing apparatus comprising:

first coordinate input means;

second coordinate input means;

selecting means for selecting an input type by determining whether an input was made by one of said first coordinate input means and said second coordinate input means or by both of said first coordinate input means and said second coordinate input means; and

determining means for determining whether drawing processing or editing processing is performed for a coordinate value input by said first coordinate input means and/or said second coordinate input means on the basis of the input type selected by said selecting means.

8. An information processing apparatus according to claim 7, further comprising discriminating means for discriminating whether a coordinate value input by said first coordinate input means and/or said second coordinate input means exists inside a predetermined region of an input area.

9. An information processing apparatus according to claim 7, wherein said first coordinate input means is comprised of a pen input and said second coordinate input means is comprised of a touch panel.

10. An information processing apparatus according to claim 9, wherein said first and second input means detect input coordinates by different methods.

11. An information processing apparatus according to claim 10, wherein said second coordinate input means detects the input coordinates by a change in resistance value.

12. An information processing apparatus according to claim 10, wherein said first coordinate input means detects the input coordinates by a transmission time of an acoustic wave.

13. An information processing method for an information processing apparatus which includes first coordinate input means and second coordinate input means, said method comprising the steps of:

selecting an input type by determining whether an input was made by one of the first coordinate input means and the second coordinate input means or by both of the first coordinate input means and the second coordinate input means; and

determining a drawing attribute on the basis of the input type selected in said selecting step and drawing a line according to the determined drawing attribute.

14. An information processing method for an information processing apparatus which includes first coordinate input means and second coordinate input mean, said method comprising the steps of:

selecting an input type by determining whether an input was made by one of the first coordinate input means and the second coordinate input means or by both of the first coordinate input means and the second coordinate input means; and

determining whether drawing processing or editing processing is performed for a coordinate value input by the first coordinate input means and/or the second coordinate input means on the basis of the input type selected in said selecting step.

15. A computer-readable memory in which program codes for an information processing apparatus which includes first coordinate input means and second coordinate input means are stored, the program codes comprising:

code for selecting an input type by determining whether an input was made by one of the first coordinate input means and the second coordinate input means or by both of the first coordinate input means and the second coordinate input means; and

code for determining a drawing attribute on the basis of the input type selected in said selecting step and drawing a line according to the determined drawing attribute.

16. A computer-readable memory in which program codes for an information processing apparatus which includes first coordinate input means and second coordinate input mean are stored, the program codes comprising:

code for selecting an input type by determining whether an input was made by one of the first coordinate input means and the second coordinate input means or by both of the first coordinate input means and the second coordinate input means; and
