Abstract

An information processing device of an aspect of the invention has display means having a display region; operation means, having a contact region, for outputting a position signal indicating the position of a contact operation in the contact region; range decision means for deciding a target range of the display region based on the position signals for two points from the operation means; processing menu display means for causing the display means to display a processing menu at a position corresponding to the target range of the display region; processing decision means for deciding the processing of the processing menu corresponding to the position of the contact operation in the contact region; and processing execution means for executing the processing on the target range of the display region.

Claims

1. An information processing device, comprising:

display means for displaying information;

operation means, having a contact region corresponding to a display region of the display means, for detecting a contact operation in the contact region and outputting a position signal indicating the position of the contact operation in the contact region;

range decision means for deciding a target range of the display region, based on the position signals for two points from the operation means;

processing menu display means for causing the display means to display a processing menu for selection of various processing, at a position corresponding to the target range of the display region decided by the range decision means;

processing decision means for deciding processing of the processing menu corresponding to the position of the contact operation in the contact region, based on the position signal for a third point from the operation means; and

processing execution means for executing the processing decided by the processing decision means on the target range of the display region decided by the range decision means.

2. The information processing device according to claim 1, wherein the processing menu display means causes the display means to display the processing menu at a position set in advance for the target range of the display region.

3. The information processing device according to claim 1, further comprising identification means for identifying whether a hand performing the contact operation in the contact region is the right hand or the left hand, and for identifying two fingers of the contact operation, wherein the processing menu display means causes the display means to display the processing menu at a position relative to the target range of the display region associated with the combination of the hand and the two fingers, based on the hand and the two fingers identified by the identification means.

4. The information processing device according to claim 1, wherein, when the position of the contact operation indicated by the position signals for two points from the operation means changes, the range decision means re-decides the target range of the display region.

5. The information processing device according to claim 1, wherein the range decision means decides the target range of the display region only when the position signals for two points are received simultaneously from the operation means.

6. A display information editing method of an information processing device which has display means for displaying information and operation means having a contact region corresponding to a display region of the display means, comprising the steps of:

detecting a contact operation in the contact region, and generating a position signal indicating the position of the contact operation in the contact region;

deciding a target range of the display region based on the position signals for two points;

causing the display means to display a processing menu for selection of various processing, at a position corresponding to the decided target range of the display region;

deciding processing of the processing menu corresponding to the position of the contact operation in the contact region, based on the position signal for a third point; and

executing the decided processing on the decided target range of the display region.
