Information processing apparatus, information processing method, information processing program, and mobile terminal device

An information processing method, comprising:

• providing an input operation portion on a housing of a mobile apparatus;
• when a plurality of contents are list-displayed and in response to an operation of the input operation portion, comparing respective ones of the plurality of contents to one another, determining a plurality of metadata items for respective ones of the plurality of contents based on the comparison, and rearranging the plurality of contents into a 3D-matrix in accordance with predetermined three axes, wherein the 3D-matrix includes a plurality of planes each containing a respective group of contents of the plurality of contents;
• and
• displaying on a display portion of the mobile phone apparatus the respective groups of contents of the plurality of contents arranged in the 3D-matrix by the 3D-matrix arranging portion, in a manner that luminance is gradually reduced in a direction from contents on a front-most plane of the plurality of planes to contents on a rear-most plane, and transmittance is gradually increased in the direction from the contents on the front-most plane to the contents on the rear-most plane,
• wherein respective ones of the plurality of metadata items are of different types from one another, and respective ones of the three axes correspond to different types of metadata items of the plurality of contents.

A mobile apparatus, comprising:

• a processor;
• an input operation portion;
• and
• a memory including a non-transitory computer-readable medium storing instructions that, when executed by the processor cause the mobile phone apparatus to perform operations comprising:
• when a plurality of contents are list-displayed and in response to an operation of the input operation portion, causing the mobile apparatus to compare respective ones of the plurality of contents to one another, determine a plurality of metadata items for respective ones of the plurality of contents based on the comparison, and rearrange the plurality of contents into a 3D-matrix in accordance with predetermined three axes, wherein the 3D-matrix includes a plurality of planes each containing a respective group of contents of the plurality of contents;
• and
• causing the mobile apparatus to display on a display portion thereof the respective groups of contents of the plurality of contents arranged in the 3D-matrix by the 3D-matrix arranging portion, in a manner that luminance is gradually reduced in a direction from contents on a front-most plane of the plurality of planes to contents on a rear-most plane, and transmittance is gradually increased in the direction from the contents on the front-most plane to the contents on the rear-most plane,
• wherein respective ones of the plurality of metadata items are of different types from one another, and respective ones of the three axes correspond to different types of metadata items of the plurality of contents.
