Patent ID: 8200350

Claim:
A content reproducing apparatus, comprising: a recording unit that analyzes frequency components of each of plural content data items to determine plural content impression values representing characteristics of the content data item, records the plural content impression values for each of the plural content data items, the content impression values obtained by digitizing the plural content data items based on the frequency analysis of the plural content data items, registers an indicator for each of the plural content data items at a respective position in a three-dimensional spatial area having three orthogonal axes based on an assignment of each of the plural content impression values of a content data item to an axis of the three-dimensional spatial area, converts the three-dimensional spatial area into a two-dimensional plane by projecting the three-dimensional spatial area onto the two-dimensional plane, displays, in a selection area, the indicator for each of the plural content data items at a position in the two-dimensional plane along orthogonal axes obtained by projecting the three orthogonal axes of the three-dimensional spatial area, and registers a list of the plural content data items in the selection area of the two-dimensional plane, the selection area set based on a reference impression value set as a reference; a reproducing unit that reproduces the plural content data items; an evaluation-value detecting unit that detects evaluation values of the plural content data items registered in the list according to reproduction of the plural content data items by the reproducing unit; a selection-area changing unit that changes the selection area based on the evaluation values detected by the evaluation-value detecting unit; and a list correcting unit that corrects the list according to the selection area changed by the selection-area changing unit.
