  • Publication number: 20130297260
    Abstract: An analysis sever capable of performing analysis among a large amount of sensor data in order to obtain an analysis result that a reader desires and outputting the result instantaneously. The analysis server rearranges the sensor data acquired from a sensor node into time series data. The analysis is performed separately for time trigger analysis (D) and for event trigger analysis (F) depending on analysis contents. In the time trigger analysis (D), analysis processing that is basically needed when visualizing a state of an organization is performed. In the event trigger analysis (F), an analysis result obtained by the time trigger analysis (D) is processed using the reader's desired information and is outputted.

  • Patent number: 8290776
    Abstract: Voice of plural participants during a meeting is obtained and dialogue situations of the participants that change every second are displayed in real time, so that it is possible to provide a meeting visualization system for triggering more positive discussions. Voice data collected from plural voice collecting units associated with plural participants is processed by a voice processing server to extract speech information. The speech information is sequentially input to an aggregation server. A query process is performed for the speech information by a stream data processing unit of the aggregation server, so that activity data such as the accumulation value of speeches of the participants in the meeting is generated. A display processing unit visualizes and displays dialogue situations of the participants by using the sizes of circles and the thicknesses of lines on the basis of the activity data.

    Abstract: Disclosed herein is a system for keeping sensing of mass data of members of an organization with respect to states of their meeting and activities and analyzing and evaluating their interactions according to those sensor data. Interaction data includes first information denoting whether or not a terminal unit has faced a different terminal unit and second information denoting a state of the terminal unit and excluding information denoting positions of the terminal unit and the first information. An interaction data display apparatus includes a receiving unit for receiving interaction data from the terminal unit and a display unit for displaying the received interaction data. The display unit displays the first and second information items included in the interaction data received by the receiving unit so as to be related to each other according to times at which those first and second information items are obtained respectively.

  • Publication number: 20120139750
    Abstract: There is disclosed a sensor node capable of transmitting and receiving a large amount of data or data desired to be reliable without missing data, while preventing battery exhaustion and unnecessary compression of the transmission bandwidth. A name-tag type sensor node includes a detector for detecting connection of an external power supply. When the detector detects that the external power is supplied, the name-tag type sensor node transmits and receives a large amount of data, such as bulk transmission data, at an increased frequency by means of a data selector, a communication timing controller, and a wireless communication controller. Alternatively, the name-tag type sensor node transmits and receives the data desired to be reliable, such as rewriting data of firmware.

  • Patent number: 8073420
    Abstract: There is provided a sensor node management method in which a user is unconscious of a service break even when a sensor mode has failed among a plurality of sensor nodes assuming intermittent operation. Moreover, it is possible to provide a flexible sensor node management method capable of freely modifying the observation grading (space, time) in accordance with a user's desire. A base station (30) for containing a plurality of intermittently operating sensor modes includes a sensor management table (4) for managing the sensor nodes, a group management table (5) for grouping a plurality of sensor nodes, and an operation timing control unit (3). The operation timing control unit (3) decides the operation interval and the relationship for starting each of the sensor nodes. Moreover, the base station and the sensor node have a counter value as a reference of the sensor node operation interval and the operation start phase, which are periodically synchronized.
