Handheld terminal and control method and control program therefor

A control method for a handheld terminal, comprising the steps of:

• causing a music reproduction section to reproduce and output a piece of music in accordance with a reproduction list;
• causing a motion recognition section to detect motion of the terminal in real space and determine whether or not the detected motion corresponds to a motion situation in which the terminal is moving in real space;
• causing a distance calculation section to obtain, on the basis of motion information which is derived from the motion of the terminal and supplied from the motion recognition section, a movement distance of the terminal in real space when the motion recognition section determines that the terminal is in a motion situation in which the terminal is moving in real space;
• causing a threshold determination section to compare the movement distance obtained by the distance calculation section with a predetermined distance determination threshold value and determine whether or not the movement distance exceeds the distance determination threshold value;
• and
• causing a reproduction list control section to change the reproduction list of music to be reproduced by the music reproduction section, when the threshold determination section determines that the movement distance exceeds the distance determination threshold value.

A control program configured to cause a handheld terminal to execute processing, the processing comprising:

• a music reproduction processing operation for reproducing and outputting a piece of music in accordance with a reproduction list;
• a motion recognition processing operation for detecting motion of the terminal in real space and determining whether or not the detected motion corresponds to a motion situation in which the terminal is moving in real space;
• a distance calculation processing operation for obtaining, on the basis of motion information which is derived from the motion of the terminal and generated in the motion recognition processing operation, a movement distance of the terminal in real space when the motion recognition processing operation determines that the terminal is in a motion situation in which the terminal is moving in real space;
• a threshold determination processing operation for comparing the movement distance obtained in the distance calculation processing operation with a predetermined distance determination threshold value and determining whether or not the movement distance exceeds the distance determination threshold value;
• and
• a reproduction list control processing operation for changing the reproduction list of music to be reproduced in the music reproduction processing operation, when the threshold determination processing operation determines that the movement distance exceeds the distance determination threshold value.
