Abstract

According to one embodiment, an information processing apparatus comprises a touch screen display, a display controller, a copy screen image display module and a pointing module. The display controller is configured to control the touch screen display and an external display. The copy screen image display module is configured to display on a screen of the touch screen display a copy screen image which is obtained by copying a screen image which is displayed on a screen of the external display. The pointing module is configured to designate a position on the screen image of the external display, the position corresponding to a touch position on the copy screen image, based on a relative position of the touch position in relation to the copy screen image.

Claims

1. An information processing apparatus comprising:

a touch screen display;

a display controller configured to control the touch screen display and an external display;

a copy screen image display module configured to display a copy screen image on a screen of the touch screen display, the copy screen image being obtained by copying a screen image which is displayed on a screen of the external display; and

a pointing module configured to designate a position on the screen image of the external display, the position corresponding to a touch position on the copy screen image, based on a relative position of the touch position in relation to the copy screen image.

2. The information processing apparatus of claim 1, wherein the copy screen image display module is configured to display a screen image, which is obtained by copying a designated part of the screen image of the external display, on the screen of the touch screen display as the copy screen image.

3. The information processing apparatus of claim 1, further comprising:

a virtual keyboard display module configured to display a virtual keyboard on the screen of the touch screen display, the virtual keyboard comprising a plurality of virtual keys for inputting key codes; and

a code data generating module configured to select a virtual key from the plurality of virtual keys, which corresponds to a touch position on the screen of the touch screen display, and to generate code data corresponding to the selected virtual key.

4. An information processing apparatus comprising:

a touch screen display;

a display controller configured to display a first screen image corresponding to a first region of a virtual screen on the touch screen display and to display a second screen image corresponding to a second region of the virtual screen on an external display;

a copy screen image display module configured to display a copy screen image in a display area of the first screen image on the touch screen display, the copy screen image being obtained by copying the second screen image; and

a pointing module configured to designate a position on the second screen image of the external display, the position corresponding to a touch position on the copy screen image, based on a relative position of the touch position in relation to the copy screen image.

5. The information processing apparatus of claim 4, wherein the copy screen image display module is configured to display a screen image, which is obtained by copying a designated part of the second screen image of the external display, on a screen of the touch screen display as the copy screen image.

6. A pointing method for designating a position on a screen image which is displayed on a screen of an external display, in accordance with a touch position on a touch screen display, comprising:

displaying a copy screen image on a screen of the touch screen display, the copy screen image being obtained by copying the screen image which is displayed on the screen of the external display; and

designating a position on the screen image of the external display, the position corresponding to a touch position on the copy screen image, based on a relative position of the touch position in relation to the copy screen image.

7. The pointing method of claim 6, wherein said displaying the copy screen image comprises displaying a screen image, which is obtained by copying a designated part of the screen image of the external display, on the screen of the touch screen display as the copy screen image.
