1. A portable electronic apparatus comprising:

  • a content storage unit configured to store content data;

    a display unit configured to display a screen showing at least a title of a content data stored in the content storage unit;

    an acceleration detection unit configured to detect an acceleration from a movement of the whole said portable electronic apparatus, the acceleration unit configured to detect the acceleration on the basis of detecting a movement of the portable electronic apparatus in a direction perpendicular to the screen and a movement of the portable electronic apparatus in a direction parallel to the screen;

    an evaluation-signal generation unit configured to perform a predetermined process based on said acceleration detected by said acceleration detection unit in order to generate an evaluation signal representing an amplitude and positive or negative polarity of said acceleration;

    a control unit configured to produce a result of determination as to whether said portable electronic apparatus has been driven to make a predetermined movement on the basis of a vacillating acceleration force indicated by said evaluation signal, and perform a predetermined operation on the basis of said result of determination; and

    a reproduction unit configured to reproduce the content data from the content storage unit,wherein while the portable electronic apparatus is turned on, said control unit keeps said acceleration detection unit in an on state while said reproduction unit is reproducing the content data and turns off said acceleration detection unit when the reproducing of the content data is stopped.
