Mood score calculation apparatus and mood score calculation method

1. A mood score calculation apparatus for specifying an employee's mental health state without imposing a burden on the employee, the mood score calculation apparatus comprising:

an administrator terminal including a manipulation information collection unit, a manipulation time variation analysis unit, a mood score calculation unit, and a result display unit;

at least one employee terminal, the employee terminal including at least a keyboard for generating key inputs obtained by the employee while carrying out tasks during the course of employment, the at least one employee terminal having a manipulation information acquiring unit for acquiring a manipulation history of the employee including the key inputs obtained from the employee, the manipulation information acquiring unit including

a memory device that stores the manipulation history of the employee on the at least one employee terminal;

a network provided for transmitting the manipulation histories from the at least one employee terminal to the manipulation information collection unit; and,

an arithmetic device that classifies the manipulation history into any one of a verbal task and a spatial task on the basis of the type of input device or application used by the employee as indicated by the manipulation history, and utilizes the manipulation time variance analysis unit to determine a variation of the manipulation time interval in each manipulation of a verbal task and a spatial task of each employee by creating a table setting forth variations in manipulation time intervals for verbal tasks and variations in manipulation time intervals for spatial tasks for each employee and calculating a fractal dimension based upon said variations within a predetermined period of time, the manipulation time variance analysis unit determining a regression formula having coordinates and calculating a determinant indicating a matching degree of the coordinates of the regression formula to calculate a mood score of the employee, wherein if the determinant is smaller than a threshold value represented by the fractal dimension, then the mood score is determined to be abnormal, and outputs information on the mood score to generate a mood score analysis result image arranged to be displayed by the result display unit on a display device, the mood score analysis result image including a field for selecting an employee terminal ID, fields for inputting start and end of a display target period, and a section for calculating the mood score.

2. The mood score calculation apparatus according to claim 1 , wherein the memory device stores a manipulation history for a routine manipulation performed by an employee one or more times for a predetermined period of time as an employee's manipulation history on a predetermined device, and

the arithmetic device classifies the manipulation history of the routine manipulation into any one of the verbal task and the spatial task on the basis of a predetermined algorithm, calculates the mood score of the employee on the basis of a relative relationship between the manipulation histories of the routine manipulations for each of the verbal task and the spatial task specified in the classification, and outputs information on the mood score to a predetermined output target.

3. A mood score calculation method for specifying an employee's mental health state without imposing a burden on the employee, the method implemented by an information processing device, the method comprising:

providing an administrator terminal including a manipulation information collection unit, a manipulation time variation analysis unit, a mood score calculation unit, and a result display unit;

providing at least one employee terminal including at least a keyboard for generating key inputs obtained by an employee while carrying out tasks during the course of employment, the at least one employee terminal having a manipulation information acquiring unit for acquiring a manipulation history of the employee including the key inputs obtained from the employee, the manipulation information acquiring unit including a memory device that stores the manipulation history of the employee on the at least one employee terminal

providing a network for transmitting the manipulation histories from the at least one employee terminal to the manipulation information collection unit;

classifying the manipulation history into any one of a verbal task and a spatial task on the basis of the type of input device or application used by the employee as indicated by the manipulation history;

utilizing the manipulation time variance analysis unit to determine a variation of the manipulation time interval in each manipulation of a verbal task and a spatial task of each employee by creating a table setting forth variations in manipulation time intervals for verbal tasks and variations in manipulation time intervals for spatial tasks for each employee and calculating a fractal dimension based upon said variations within a predetermined period of time, and utilizing the manipulation time variance analysis unit to determine a regression formula having coordinates and to calculate a determinant indicating a matching degree of the coordinates of the regression formula to calculate a mood score of the employee wherein if the determinant is smaller than a threshold value represented by the fractal dimension, then the mood score is determined to be abnormal; and,

outputting information on the mood score to generate a mood score analysis result image arranged to be displayed by the result display unit on a display device, the mood score analysis result image including a field for selecting an employee terminal ID, fields for inputting start and end of a display target period, and a section for calculating a mode score.

4. The mood score calculation method according to claim 3 , wherein the information processing device causes the memory device to store a manipulation history for a routine manipulation performed by an employee one or more times for a predetermined period of time as an employee's manipulation history on a predetermined device, and

the information processing device classifies the manipulation history of the routine manipulation into any one of the verbal task and the spatial task on the basis of a predetermined algorithm, calculates the mood score of the employee on the basis of a relative relationship between the manipulation histories of the routine manipulations for each of the verbal task and the spatial task specified in the classification, and outputs information on the mood score to a predetermined output target.
