  • Publication number: 20210090460
    Abstract: An information processing system visualizes brain states to optimize rehabilitation programs for rapid feedback of their effects to a patient and healthcare staff, to thereby promote the efficiency of rehabilitation. An embodiment of the system includes: a storage section that stores test-result brain-state relationship information associating results of activities of multiple examinees subjected to predetermined tests with brain states of the examinees; an input section that accepts a first test result as the result of the activity of a first examinee subjected to the predetermined tests; a control section that estimates the brain state from the first test result on the basis of the test-result brain-state relationship information; and an output section that outputs the estimated brain state.

  • Patent number: 7398185
    Abstract: A system recognizes an occurrence of offline action when a state in which a person-to-be-recorded does not perform a computer operation continues for or longer than a predetermined time. Then, action related information such as action schedule information about a person-to-be-recorded, movement position information indicating the position of a person-to-be-recorded, immobile target position information indicating the position of an immobile target such as a building, a point on a map, etc., position-action correspondence associating the immobile target position information with the content of offline action, etc. is acquired. According to the information, the content of the offline action is estimated. When a next computer operation is detected, the estimated content is displayed for confirmation by the person-to-be-recorded. The system accepts and records the input of supplement, amend, approve, etc. from the person-to-be-recorded.

  • Publication number: 20080126289
    Abstract: An apparatus registers a participant instance with an incentive inputted by a member “a” (a participant), a searcher instance as supplement to the participant instance inputted by a member “b” (a searcher), and an approval incentive added by a member “c” (an approver) in an instance database 11. Then, when a solver “d” who viewed the participant instance and proposed a solution requests display of incentive allocation, the apparatus sums up the incentive for the participant instance from the instance database 11 and the approval incentive to calculate incentive allocation between the searcher of the associated searcher instance and the solver based on a pre-determined rate. The apparatus further weights, using pre-determined rate, on the allocation to the searcher of searcher instance referenced by others. The apparatus displays the calculated incentive allocation on a terminal 2d of the solver “d”.

  • Publication number: 20080120623
    Abstract: In a work-flow process, a work-flow apparatus, and a computer-readable medium storing a work-flow program for delivering work requests to stations in an organization: a station in charge of executing each work request is determined by comparing the work request with work definitions, and the work request is delivered to the station in charge; acceptance or rejection of the work request by the station in charge is recorded in a request-processing history in association with an identifier of the work request; and the number of work requests which have been improperly or indirectly delivered to each station is obtained on the basis of the numbers of work requests which have been rejected by the station. When the number of work requests which have been improperly or indirectly delivered to each station is greater than a predetermined number, the work definition for the station is determined to be corrected.

  • Patent number: 7254481
    Abstract: An action support apparatus displays a destination specification screen for specifying a destination, and receives from the user a specification of a general destination. If a general destination is specified, then the apparatus determines a detailed destination, referencing a knowledge DB. If there is a plurality of detailed destinations with respect to the general destination, then any one of them is set to the user's destination. Next, the apparatus sets the current location as the starting point, and generates a planned route from the starting point to the destination based on a map DB and an internal clock. Furthermore, the apparatus reads a filtering rule from a filtering DB, and extracts as recommended information facility information of facilities suited to the user from a facility information DB. Depending on the filtering rule, it is also acceptable to use user information in a user DB in the extraction of the recommended information.

  • Publication number: 20040193586
    Abstract: A database search system for searching a database for data measures an input number of search conditions input during a period from a start to an end of search processing or a necessary time taken from the start to the end of the search processing, receives an input of a message describing know-how information corresponding to contents of the search processing from a user, in a case where the measured input number exceeds a predetermined threshold value, and stores the input message under a condition that the input message is associated with a predetermined search condition during an execution period of the search processing. During execution of the search processing, the search conditions input by the user are compared with stored search conditions every time the search conditions are received, and in a case where a plurality of or more search conditions are matched with each other, the associated message is output to the user.
