摘要:
Music content are reproduced in the order of the newest time information that has been registered. A music content database 7 has stored a plurality of music content. Each music content has been stored in the music content database 7 along with a time stamp that is time information that represents a time at which the music content was registered in the music content database 7. A CPU 3 creates play lists corresponding to, for example, tempos. The created play lists are stored in a play list database 8. The CPU 3 selects a play list corresponding to a moving tempo obtained from a tempo detection section 9 and selects music content in the order of the newest time information registered from the music content corresponding to the selected play list. The selected music content are supplied to a decoder and amplification section 12 and reproduced by a head phone 14.

Apparatus consisting of an information processing terminal (1) or a communications system including an information providing device (30), the apparatus comprising: bio-information detecting means (18) for detecting bio-information on a user; psychology analyzing means (19) for analyzing the user's psychology corresponding to the detected bio-information; information generating means (21) for generating information matching the result of psychology analysis; and output means (15, 24) for providing the generated information as an output, wherein: the information processing terminal (1) or the information providing device (30) of the communications system comprises word extracting means (27) for extracting a word frequently used by the user, storage means for word storing means (22) for storing the word extracted and wherein the information generated by the information generating means (21, 32) is generated from the extracted word.
摘要:
Vertical-component extracting means (2) extracts a vertical component from an acceleration vector corresponding to body movement of a user from a three-axis acceleration sensor (1), and the vertical-component is separated by a high-band/low-band separating unit (3) into a high-band component and a low-band component. Using these components, a peak detection/determination processing unit (4) detects a peak-position candidate of action of the user in the vertical direction, identifies a peak-position candidate on the basis of an energy ratio between the high-band component and the low-band component, performs waveform matching regarding a predetermined range including each peak-position candidate, thereby determining a peak position, and detects body movement on the basis of the peak position, and a step-position analyzing unit (5) detects a body-movement pitch. Accordingly, without being affected by various types of noise, it becomes possible to accurately detect body movement of the user in the vertical direction, and also to accurately detect the body-movement pitch of the user as needed.
摘要:
By allowing the movement of a user to affect the playback of content, the entertainment characteristic or uplifting spirits derived from content playback itself can be enhanced. The timing at which the user places his/her foot on the ground while walking or the timing at which the user shakes or changes from swinging in one direction to swinging to another direction is detected. Then, content, such as a music piece or moving pictures, is played back by allowing the timing of beats or bars of the music piece or the timing of scene changes or cut changes of the moving pictures to be synchronized with the timing of the movement of the user.
摘要:
[Object] There is proposed a mechanism that allows for a higher noise cancellation effect by operating a plurality of units in coordination. [Solution] An information processor including a signal processing section that: acquires a first signal to be detected by an acoustic input section of a first unit including the acoustic input section disposed within a predetermined distance from one ear hole of a user in a state of being worn by the user; acquires a second signal, which indicates a noise generated from a noise source, to be acquired by a second unit; and generates a noise cancellation signal directed to the noise on the basis of the first signal and the second signal.
