Abstract

An information processing device includes a first display, a touch sensor on a screen of the first display detects a position of an object on the screen and detects approach of a pen within a distance above the screen, a pen input processing acquires a position of the pen on the screen by switching between a first input mode for displaying a movement locus of the pen on the screen based on the position of the pen and a second input mode for making a second display sets to a specific arrangement relation with the first display displays the movement locus of the pen and an input switch processing which switches between the first input mode and the second input mode alternately in accordance with a movement of the pen performed in a non-contact state based on the specific arrangement relation after detection of the pen.

First claim

What is claimed:

1. An information processing device comprising:
a first display;
a touch sensor which is arranged on a screen of the first display and which detects a contact position of an object on the screen, and detects approach of a pen which approaches a point which is located within a threshold distance above the screen of the first display in a state that the pen is out of contact with the screen and the position of the pen above the screen;
a pen input processing section which acquires a contact position of the pen on the screen of the first display that the touch sensor detects and executes pen input processing by switching between a first pen input mode for displaying a movement locus of the pen on the screen of the first display which is based on the contact position of the pen and a second pen input mode for displaying the movement locus of the pen on a second display which is set to a specific arrangement relation with the first display; and
an input switch processing section which switches between the first pen input mode and the second pen input mode alternately in accordance with a movement operation of the pen which is performed in a non-contact state which is based on the specific arrangement relation after detection of approach of the pen by the touch sensor.

2. The information processing device according to claim 1 further comprising:
an arrangement information storage section which stores arrangement information which indicates an arrangement relation between the first display and the second display, wherein
in a case where a hovering state that the pen maintains a state of out-of-contact with the screen of the first display and a state of approaching the point which is located within the threshold distance for a fixed time period is detected by the touch sensor and thereafter an operation of moving the pen above the screen of the first display in a direction of indicating a switching destination screen is detected on the basis of the arrangement information, the input switching processing section switches to one input mode which corresponds to the screen of the switching destination between the first input mode and the second input mode.

3. The information processing device according to claim 1 , further comprising:
a screen size information storage section which stores screen size information which indicates the size of the screen of the second display; and
a coordinates transformation section which transforms coordinates of the pen on the screen of the first display to coordinates of the pen on the screen of the second display on the basis of the screen size information that the screen size information storage section stores, wherein
the pen input processing section makes the second display displays the movement locus of the pen which is based on the coordinates of the pen on the screen of the second display that the coordinates transformation section transforms in the second pen input mode.

4. The information processing device according to the claim 3 , further comprising:
a main control which executes processing which is based on an OS (Operating System); and
an independent built-in control which is different from the main control, wherein
the main control includes the pen input processing section and
the built-in control includes the input switch processing section and the coordinates transformation section.

5. An information processing system comprising:
a first display;
a touch sensor which is arranged on a screen of the first display and which detects a contact position of an object on the screen, and detects approach of a pen which approaches a point which is located within a threshold distance above the screen of the first display in a state that the pen is out of contact with the screen and the position of the pen above the screen;
a second display which is set to a specific arrangement relation with the first display;
a pen input processing section which acquires a contact position of the pen on the screen of the first display that the touch sensor detects and executes pen input processing by switching between a first pen input mode for making the first display displays a movement locus of the pen on the screen of the first display which is based on the contact position of the pen and a second pen input mode for making the second display displays the movement locus of the pen; and
an input switch processing section which switches between the first pen input mode and the second pen input mode alternately in accordance with a movement operation of the pen which is performed in a non-contact state which is based on the specific arrangement relation after detection of approach of the pen by the touch sensor.

6. A method of controlling an information processing system which includes a first display, a touch sensor which is arranged on a screen of the first display and which detects a contact position of an object on the screen, and detects approach of a pen which approaches a point which is located within a threshold distance above the screen of the first display in a state that the pen is out of contact with the screen and the position of the pen above the screen and a second display which is set to a specific arrangement relation with the first display, comprising:
acquiring a contact position of the pen on the screen of the first display that the touch sensor detects and executing pen-input processing by switching between a first pen input mode for displaying a movement locus of the pen on the screen of the first display which is based on the contact position of the pen and a second pen input mode for making the second display displays the movement locus of the pen by a pen input processing section; and
after detection of approach of the pen by the touch sensor, switching between the first pen input mode and the second pen input mode alternately in accordance with a movement operation of the pen which is performed in a non-contact state which is based on the specific arrangement relation by an input switch processing section.
