A body motion detecting method calculates an acceleration-of-gravity vector from acceleration vectors, which are detection outputs of a multi-axial acceleration sensor. The method extracts a vertical component of acceleration, using the acceleration vectors from the acceleration sensor and the calculated acceleration-of-gravity vector. The method further detects peaks in the extracted vertical component of acceleration, and detects body motion in the vertical direction by analyzing the detected peaks. Related body motion detecting device and computer readable medium are also described.

Music contents assigned to play lists are reproduced so as to correspond to user's preference. A music content database 7 has stored a plurality of music contents. A CPU 3 creates genre ranks such that music contents that have been more frequently, for example, reproduced are more highly ranked. In addition, the CPU 3 creates play lists corresponding, for example, to tempos and stores the created play lists 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 categorized as a highly ranked genre in the genre ranks from those corresponding to the selected play list. The selected music content is supplied to a decoder and amplifier section 12 and then reproduced from a head phone 14.

摘要:
In an image display system that displays the condition of a person under measurement in a visible form, the person carries a PDA (10). The PDA (10) includes a bio-sensor (11) to detect bio-information on the person and an environmental information sensor (12) to acquire information on the environment around the person. The PDA (10) sends the acquired information to an image display device (20) which is connected to the PDA (10) via a network (100). The image display device (20) includes a CPU (29) that judges the condition of the person on the basis of bio-information and environmental information, generates an image representing the condition of the person and displays the image on a display unit (23).
摘要:
State information of a user is detected via a biometric information sensor (21) and so on and the state information is accumulated in a nonvolatile memory (14) by associating it with a content ID of content that is being used. A recommendation request including the state information detected at that time via the biometric information sensor (21) and so on and a predetermined extraction condition is generated and transmitted. Provided information transmitted in response to the recommendation request is received and is provided to the user. When an information provision request is received, information to be provided is extracted from the information stored in the nonvolatile memory (14) based on the state information and extraction condition included in the received information provision request and the extracted information is transmitted to a requesting source. With the above-described process, appropriate information can be provided based on a parameter according to feeling and/or behavior of the user of the moment.
摘要:
A vertical component is extracted from an acceleration vector corresponding to body movement of a user from a three-axis acceleration sensor, and the vertical-component is separated by a high-band/low-band separating unit into a high-band component and a low-band component. Using these components, a peak detection/determination processing unit 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 detects a body-movement pitch.
摘要:
Reproducing characteristics of an audio sound are controlled by an audio controller 8 and reproducing characteristics of a video image are controlled by a video controller 11. Whether or not a viewpoint of the user is directed to a display 13 side of a television receiver is detected by a viewpoint detector 14. On the basis of a detection signal from the viewpoint detector 14, a discriminating unit 15 discriminates which of a normal monitoring state, a “while watching” state, and the “concentration” state the present state corresponds to, and generates a control signal to control the reproducing characteristics so as to be adaptive to the state. If it is determined that the present state changes from the “while watching” state to the “concentration” state, a sound volume is reduced and the reproducing characteristics are automatically switched so as not to obstruct the concentration.
