Information processing method, information processing device, image output device, information processing program, and recording medium

An information processing device for processing information, the information processing device comprising a screen for displaying at least one key that is selectable by touching the screen or locally approaching the screen, and a detection region within which selecting of the key is detectable, the information processing device comprising:

• an operation managing section for determining a key arrangement on the screen in accordance with an operation status of an apparatus to which the information processing device is provided;
• and
• a detection managing section for updating positional data of the detection region on the screen so that an extent of the detection region is adjusted in accordance with a spatial density of the key arrangement determined by the operation managing section.

An information processing program for causing a computer to execute a method for processing information that defines a dimension of a detection region of a key displayed on a screen of an information processing device, where the detection region is adjacent to an invalid region, the detection region being a region in which touching of the screen in this region or local approaching to this region is detectable, and the invalid region being a region in which the touching of the screen in this region or local approaching to this region is not detectable, the method comprising:

• when a distance across the invalid region from an edge of a key display region exceeds a first threshold value,
• generating, by the information processing device, a detection region data that defines an extent of the detection region with respect to a dimension of the key display region so that the detection region becomes larger than the key display region by utilizing the invalid region.

An information processing program for causing a computer to function as an information processing device for processing information, the information processing device comprising a screen for displaying at least one key that is selectable by touching the screen or locally approaching the screen, and a detection region within which selecting of the key is detectable, the information processing device comprising:

• an operation managing section for determining a key arrangement on the screen in accordance with operation status of an apparatus to which the information processing device is provided;
• and
• a detection managing section for updating positional data of the detection region on the screen so that an extent of the detection region is adjusted in accordance with a spatical density of the key arrangement thus determined by the operation managing section.

A recording medium in which an information processing program is stored,

• the information processing program causing a computer to execute a method for processing information that defines a dimension of a detection region of a key displayed on a screen of an information processing device, where the detection region is adjacent to an invalid region, the detection region being a region in which touching of the screen in this region or local approaching to this region is detectable, and the invalid region being a region in which the touching of the screen in this region or local approaching to this region is not detectable, the method comprising:
• when a distance across the invalid region from an edge of a key display region exceeds a first threshold value,
• generating, by the information processing device, a detection region data that defines an extent of the detection region with respect to a dimension of the key display region so that the detection region becomes larger than the key display region by utilizing the invalid region.

An information processing device for processing information, the information processing device comprising a screen for displaying at least one key that is selectable by touching the screen or locally approaching the screen, and a detection region in which selecting of the key is detectable, the information processing device comprising:

• an operation managing section for determining key arrangement on the screen in accordance with operation status of an apparatus to which the information processing device is provided;
• and
• a detection managing section for (i) judging whether or not a distance between a first point and a second point exceeds a first threshold value in the key arrangement determined by the operation managing section, and (ii) if the distance exceeds the first threshold, updating a positional data of the detection region so that the detection region is larger than a key display region of the key, the first point being on an edge of the key display region of the key and the second point being in a vacant region formed around the key display region of the key.
