Abstract

A replay mode control device in which the replay mode in reproducing music or video contents is controlled so as to be suitable for a user. A headphone of a mobile music reproducing device is provided with a vibration sensor for detecting movements of the user in the up-and-down direction. A walking movement detection unit detects the walking interval of the user based on an output of the vibration sensor. A replay mode controller manages control to adjust the replay rate of music contents to the walking interval of the user.

Claims

1. A replay control device comprising

bio-information detection means for detecting a walking pitch and a walking tempo of a user;

movement analysis means for analyzing a stepping tempo of the user based on said walking pitch and walking tempo;

content storage means configured to store and readout a plurality of content data;

replay controlling means for controlling selection among said plurality of content data in response to said stepping tempo; and

reproducing means configured to reproduce content data selected by said replay controlling means at a reproduction rate;

when the walking tempo of the user is between a first predetermined threshold and a second predetermined threshold the reproduction rate of the content data is lower than the nominal reproduction rate, when the walking tempo of the user is above a third predetermined threshold the reproduction rate of the content data is higher than the nominal reproduction rate, and when the walking tempo of the user is lower than the first predetermined threshold, or between the second predetermined threshold and the third predetermined threshold, the reproduction rate is equal to the nominal reproduction rate.

2. The replay control device according to claim 1 wherein

said replay controlling means further controls at least one of sound volume, beat sound, sound tone or title indication.

3. The replay control device according to claim 1 wherein

said bio-information detection means is mounted on the user'"'"'s body.

4. The replay control device according to claim 1 wherein

said bio-information includes acceleration or velocity of movement in an up-and-down direction of the user.

5. The replay control device according to claim 1 wherein

said bio-information detection means comprises a pressure sensor provided in a bottom of a shoe of the user;

said movement analysis means detecting a touching down of the bottom of the shoe of the user or a separation of the bottom of the shoe of the user from a surface.

6. A method for controlling a replay of recorded contents, the method comprising:

a bio-information detection step of detecting a walking pitch and a walking tempo of a user;

a movement analysis step of analyzing a stepping tempo of the user based on said walking pitch and walking tempo;

a replay controlling step of controlling selection among a plurality of content data in response to said stepping tempo; and

a reproducing step of reproducing content data selected in said replay controlling step at a reproduction rate;

whereby when the walking tempo of the user is between a first predetermined threshold and a second predetermined threshold the reproduction rate of the content data is lower than the nominal reproduction rate, when the walking tempo of the user is above a third predetermined threshold the reproduction rate of the content data is higher than the nominal reproduction rate, and when the walking tempo of the user is lower than the first predetermined threshold, or between the second predetermined threshold and the third predetermined threshold, the reproduction rate is equal to the nominal reproduction rate.

7. The method for controlling replay according to claim 6 wherein

said replay controlling step further controls at least one of sound volume, beat sound, sound tone or title indication.

8. The method for controlling replay according to claim 6 wherein

said bio-information is an acceleration or velocity in an up-and-down direction of the user during walking.

9. The method for controlling replay according to claim 6 wherein

said bio-information detection step detects a touching down of a bottom of a shoe of the user on a surface or a separation of the bottom of the shoe of the user from the surface;

and wherein

said movement analysis step detects a stepping tempo of the user based on the detection(s) of said bio-information detection step.
