FIG. 2 is a block diagram showing an example of the functional configuration of the environment control device 8. Among the functions shown in the figure, the user information storage unit 801 and the set value storage unit 803, the correction rule storage unit 804, the change history storage unit 808, and the work record storage unit 811 are realized by the memory. On the other hand, in the worker identification unit 802, the set value correction unit 805, the device control unit 806, the set value change unit 807, the trial control unit 809, and the work performance evaluation unit 810, the processor executes the program stored in the memory. It will be realized. This program is a program that can be distributed via a network such as the Internet or a non-temporary recording medium. Each function will be described below.

The user information storage unit 801 stores the user information table T1 for storing the information of the employees working in the room R. As illustrated in FIG. 3, the user information table T1 stores the user ID, height, weight, body fat percentage, facial feature amount, and priority of the employee in association with each other. Of these information, the face feature amount is data used for identifying an employee by face recognition, and is extracted based on the face image of the employee. The priority is data that is referred to for identifying a worker who is subject to environmental control when there are a plurality of employees in the room R. This priority is set in consideration of the job title, gender, age, etc. of each employee. The information stored in the user information table T1 is set by the user at the time of initial setting of the environment control device 8.

When the user instructs the start of the environment control, the worker identification unit 802 acquires image data from the camera 2 with a microphone and uses face recognition technology to identify the employee in the room R. As a result, when only one employee is specified, that employee is designated as a worker subject to environmental control. On the other hand, when a plurality of employees are identified, the employee with the highest priority among the plurality of employees is set as the worker subject to environmental control.

The setting value storage unit 803 stores the setting value table T2 that stores the setting value group for the controlled device for each employee. In this set value table T2, as illustrated in FIG. 4, the color temperature and brightness are set as the set values for the ceiling light 3, and the temperature, humidity and air volume are set as the set values for the air conditioner 4, in association with the user ID of the employee. The music genre (specifically, the music genre ID) and the volume are stored as the set values for the music playback device 5, and the scent type (specifically, the scent type ID) and the scent intensity are stored as the set values for the scent generator 6. .. Each set value stored in the set value table T2 is optimized through an environment control process described later. At the start of using the environment control device 8, a predetermined initial value is set for each employee. At that time, a template preferred by each employee may be selected and set from a plurality of templates in the initial value group.

The correction rule storage unit 804 stores the correction rule table T3 for storing the correction rule of the set value. Each correction rule stored in the correction rule table T3 is defined by three elements: a condition for correction, a type of set value to be corrected, and a content of correction. In addition, each correction rule is large, and the first correction rule for correcting at least one of temperature, humidity and air volume based on the physical information of the worker and the schedule information of the worker (more specifically, more specifically, A second correction rule to correct at least one of temperature, humidity, air volume, music genre and scent type based on the event content) and volume correction based on the current sound pressure level in the room It is classified into a third correction rule for correcting at least one of color temperature and brightness based on the current time zone and a fourth correction rule for correcting at least one of them. Among these correction rules, the first correction rule is, for example, a rule that lowers the temperature by "n" degrees when the body fat percentage of the worker is "m"% or more. The second correction rule is, for example, a rule that the music genre is set to the genre "y" when the worker is currently executing the event "x", or the latest event executed by the worker is "outside". In some cases, the rule is to lower the temperature by "n" degrees. The third correction rule is, for example, a rule in which the volume is increased by "n" steps when the sound pressure level in the room is "m" dB or more. The fourth correction rule is, for example, a rule that increases the color temperature by "n" K when the current time is in the "m" time range.

When the worker is specified by the worker identification unit 802, the set value correction unit 805 reads out the set value group associated with the specified worker from the set value table T2, and reads out the set value group. Correction is performed with reference to the correction rule table T3. Specifically, first, the physical information of the worker is read from the user information table T1, and at least one of the temperature, humidity, and air volume is corrected based on the read physical information according to the first correction rule. At that time, as a modification, the physical information of the worker may be acquired from another database that stores the medical information of each employee. Secondly, the set value correction unit 805 acquires the worker's schedule information from the worker's work PC 7, and according to the second correction rule, the acquired schedule information (more specifically, a keyword indicating the event content). At least one of temperature, humidity, air volume, music genre and scent type is corrected based on. Thirdly, the voice data is acquired from the camera 2 with a microphone, and the volume is corrected based on the sound pressure level obtained by analyzing the acquired voice data according to the third correction rule. Fourth, according to the fourth correction rule, at least one of the color temperature and the brightness is corrected based on the current time zone. As a result of these corrections, a set value group that reflects the physical information and schedule of the worker, the quietness of the room, and the current time zone is generated. Hereinafter, the set value corrected by the set value correction unit 805 is referred to as a “correction set value”.

The device control unit 806 controls each control target device based on the correction set value group generated by the set value correction unit 805. Specifically, the ceiling light 3 was controlled based on the corrected color temperature and brightness, the air conditioner 4 was controlled based on the corrected temperature, humidity and air volume, and the music playback device 5 was corrected. Control is performed based on the music genre ID and volume, and the scent generator 6 is controlled based on the corrected scent type ID and scent intensity.

The setting value changing unit 807 randomly changes any one of the correction setting value groups after being controlled by the device control unit 806. For example, among the correction set values, the corrected color temperature is reduced by a predetermined value. Then, the information related to the change is stored in the change history table T4 described later. Hereinafter, the setting value changed by the setting value changing unit 807 is referred to as a “change setting value”.

The change history storage unit 808 stores the change history table T4 described above. As illustrated in FIG. 5, the change history table T4 stores the change date and time, the type of the changed setting value, the change content, and the acceptance / rejection in association with the user ID of the worker. Among these information, acceptance / rejection is information indicating whether or not the content of the change is reflected in the setting value stored in the setting value table T2. In other words, it is information indicating whether or not the change has contributed to the improvement of the work efficiency of the worker. This acceptance / rejection is represented by two values of "true" or "false".

The trial control unit 809 trially controls the control target device based on the change setting value generated by the setting value change unit 807. For example, when the change setting value is the color temperature, the ceiling light 3 is controlled on a trial basis based on the change setting value.

After the trial control by the trial control unit 809, the work performance evaluation unit 810 acquires the line number information of the source code created by the worker from the worker's work PC 7, and then, for a predetermined time (for example, 1 hour). After the lapse of time, the line number information of the source code created by the worker is acquired again from the work PC 7. Then, by subtracting the number of lines of the former from the number of lines of the latter, the work performance of the worker under the situation where the trial control is performed is specified. Here, as a work record, the number of lines of source code created by the worker within a predetermined time is specified. When the work record is specified, this work record is compared with the work record given by the worker in the situation where the above-mentioned trial control is not performed. This work record is a work record given by the worker in a situation where each control target device is controlled based on the set value group associated with the worker in the set value table T2. Specifically, it is the latest work record of the worker stored in the work record history table T5 described later.

As a result of comparing these two work results, if the work results listed in the situation where trial control is performed exceeds the work results listed in the situation where trial control is not performed ( That is, when the work efficiency is improved in the former situation), the content of the change made by the setting value changing unit 807 is set to the setting value associated with the worker in the setting value table T2. Reflect in. For example, when the change made by the set value changing unit 807 increases the color temperature by "n" K, the color temperature associated with the operator in the set value table T2 is increased by "n" K. Let me. Then, in the change history table T4, the acceptance / rejection of this change is set to "true". In addition, the information related to the newly specified latest work record is stored in the work record history table T5. On the other hand, when the work record given in the situation where the trial control is performed is less than or equal to the work record given in the situation where the trial control is not performed (that is, under the former situation). If the work efficiency is lower or the work efficiency does not change), the content of the change made by the setting value changing unit 807 is not reflected in the setting value associated with the worker in the setting value table T2. Then, in the change history table T4, the acceptance / rejection of this change is set to "false".

The work record storage unit 811 stores the work record history table T5 described above. In this work record history table T5, as illustrated in FIG. 6, the date and time when the work record is specified and the line of the source code created by the worker within a predetermined time are arranged in association with the user ID of the worker. The number (hereinafter referred to as "the number of lines of created source code") is stored. The work record information stored in the work record history table T5 relates to the work record determined to exceed the latest work record stored in the table among the work results specified by the work record evaluation unit 810. Information only.
The above is a description of each function of the environment control device 8.

1-2. Operation Next, the environment control process executed by the environment control device 8 described above will be described with reference to the flow chart shown in FIG. 7.

When the user instructs the start of the environmental control, the worker identification unit 802 of the environmental control device 8 acquires image data from the camera 2 with a microphone and uses the face recognition technology to provide an employee in the room R. Identify the members. As a result, when only one employee is specified, that employee is set as a worker subject to environmental control, and when multiple employees are specified, among the multiple employees. The employee with the highest priority is designated as the worker subject to environmental control (step St1).

When the worker is specified by the worker identification unit 802, the setting value correction unit 805 reads out the setting value group associated with the specified worker from the setting value table T2, and reads out the setting value group. Correction is performed with reference to the correction rule table T3 (step St2). FIG. 8 is a flow chart showing an example of this set value correction process.

In the process shown in the figure, the set value correction unit 805 first reads the physical information of the worker from the user information table T1 (step St21), and according to the first correction rule, the temperature, humidity, and the temperature, humidity, and the physical information based on the read physical information At least one of the air volumes is corrected (step St22). Next, the worker's schedule information is acquired from the worker's work PC 7, and the temperature, humidity, and air volume are obtained based on the acquired schedule information (more specifically, a keyword indicating the event content) according to the second correction rule. , At least one of the music genre and the scent type is corrected (step St23). Next, the voice data is acquired from the camera 2 with a microphone, and the volume is corrected based on the sound pressure level obtained by analyzing the acquired voice data according to the third correction rule (step St24). Next, at least one of the color temperature and the brightness is corrected based on the current time zone according to the fourth correction rule (step St25). As a result of these corrections, a correction setting value group that reflects the physical information and schedule of the worker, the quietness of the room, and the current time zone is generated.

When the set value correction unit 805 generates a correction set value group, the device control unit 806 then controls each controlled device based on the generated correction set value group (step St3). Specifically, the ceiling light 3 was controlled based on the corrected color temperature and brightness, the air conditioner 4 was controlled based on the corrected temperature, humidity and air volume, and the music playback device 5 was corrected. Control is performed based on the music genre ID and volume, and the scent generator 6 is controlled based on the corrected scent type ID and scent intensity.

After the control by the device control unit 806, the setting value changing unit 807 randomly changes any one of the correction setting value groups (step St4). Then, the information related to the change is stored in the change history table T4.

When the change setting value is generated by the setting value change unit 807, the trial control unit 809 trially controls the controlled device based on the generated change setting value (step St5).

After the trial control by the trial control unit 809, the work performance evaluation unit 810 evaluates the work performance of the worker under the condition that the trial control is performed (step St6). FIG. 9 is a flow chart showing an example of this work performance evaluation process.

In the process shown in the figure, the work performance evaluation unit 810 first acquires the line number information of the source code created by the worker from the worker's work PC 7 (step St61). After that, it waits until a predetermined time (for example, 1 hour) elapses (step St62), and when the predetermined time elapses (YES in step St62), the line number information of the source code created by the worker from the work PC 7 again. (Step St63). Then, by subtracting the number of lines acquired in step St61 from the number of lines acquired in step St63, the number of lines of the source code created by the operator within a predetermined time under the situation where trial control is being performed can be obtained. Identify (step St64).

After specifying the number of source code lines, the specified number of lines is compared with the latest number of created source code lines of the worker stored in the work record history table T5 (step St65). As a result of this comparison, if the number of lines in the former exceeds the number of lines in the latter (that is, if the work efficiency is improved in the situation where trial control is performed) (step). (YES in St65), the content of the change made by the set value changing unit 807 in step St4 is reflected in the set value associated with the operator in the set value table T2 (step St66). Then, in the change history table T4, the acceptance / rejection of this change is set to "true" (step St67). In addition, the information related to the newly identified latest work record is stored in the work record history table T5 (step St68). On the other hand, as a result of the above comparison, when the number of rows of the former is less than or equal to the number of rows of the latter (that is, when the work efficiency is lower or the work efficiency does not change in the situation where trial control is performed). (NO in step St65), the content of the change made by the set value changing unit 807 in step St4 is not reflected in the set value associated with the operator in the set value table T2. Then, in the change history table T4, the acceptance / rejection of this change is set to "false" (step St69).
The above is the description of the environmental control process.

The environment control process described above is repeatedly executed until the user instructs the end of the environment control. By repeatedly executing the environment control process described above, the indoor environment is optimized so that the work efficiency of the worker is improved.

2. Modification Example The above embodiment may be modified as follows. In addition, two or more modified examples described below may be combined with each other.

2-1. Modification 1
The worker identification unit 802 identifies the employees in the room R based on the image data taken by the camera 2 with a microphone, but the method of identifying the occupants is not limited to this. For example, the worker identification unit 802 may identify the employee in the room R by cooperating with the entry / exit management system that manages the entry / exit of the employee into the room R. Alternatively, the employee present in the room R may be specified based on the position information of the mobile terminal carried by each employee.

2-2. Modification 2
The correction rule stored in the correction rule table T3 may include a fifth correction rule for correcting the music genre based on the purchase history of the worker. When the correction is performed according to the fifth correction rule, the set value correction unit 805 acquires music data or purchase history information of the music recording medium from the worker's work PC 7, and sets the music genre to the recently purchased music data or music data. Change to the music genre of the music recording medium.
Further, one or more correction rules may be omitted from the fourth correction rule from the first correction rule stored in the correction rule table T3.

2-3. Modification 3
The setting value changing unit 807 may select the setting value to be changed according to a predetermined rule instead of randomly selecting the setting value to be changed. For example, a setting value of the same type as the setting value associated with the acceptance / rejection "true" in the change history table T4 may be selected as the change target. In other words, the same type of setting value as the setting value reflected in the setting value table T2 in the past by the work performance evaluation unit 810 may be selected as the change target. By selecting the setting value to be changed in this way, there is a high possibility that the change with respect to the selected setting value is reflected in the setting value table T2. When a plurality of types of setting values are associated with the acceptance / rejection "true" in the change history table T4, the setting values of the same type as the setting values most often associated with the acceptance / rejection "true" are displayed. It may be selected as a change target.

As another example, the setting value changing unit 807 may select a setting value of a type different from the setting value associated with the acceptance / rejection "false" in the change history table T4 as the change target. In other words, a set value of a type different from the set value that has not been reflected in the set value table T2 in the past by the work performance evaluation unit 810 may be selected as the change target. This selection method also increases the possibility that changes to the selected set value will be reflected in the set value table T2. When all types of setting values are associated with acceptance / rejection "false" in the change history table T4, the same type of setting value as the setting value with the least number of associations with acceptance / rejection "false" is used. May be selected as the change target.

As another example, the setting value changing unit 807 may select a setting value for which the change history is not recorded in the change history table T4 as a change target. In other words, a setting value that has not been changed in the past may be selected as the change target.

2-4. Modification 4
The work performance evaluated by the work performance evaluation unit 810 is not limited to the number of lines of source code created by the worker. Another work record is the number of characters input to the work PC 7 by the worker. Another work record is the score of the test that the worker took on the work PC 7 or on a paper medium. When the score of the test taken on the paper medium is used as the work record, the score is input to the environment control device 8 by the operator.

2-5. Modification 5
The work performance evaluation unit 810 may consider the posture of the worker when evaluating the work performance of the worker. Specifically, in the determination of step St65 of the above environment control process, when the number of lines of the source code created by the worker is the same as the number of lines of the source code created in the past, the posture of the worker. When is good, the content of the change made by the set value changing unit 807 in step St4 may be reflected in the set value associated with the worker in the set value table T2. Here, as a method of determining whether or not the posture of the worker is good, for example, there is a method of photographing the side surface of the worker's body with a camera and performing template matching of the photographed image.

2-6. Modification 6
The brightness of the display of the work PC 7 and the character size displayed on the display may be added as control targets of the above-mentioned environment control process. In that case, the brightness of the display and the character size are further stored in the setting value table T2 in association with the user ID of the employee as the setting values for the work PC 7. Further, the correction rule table T3 further stores a sixth correction rule for correcting at least one of the brightness and the character size of the display based on the indoor illuminance measured by the illuminometer. The sixth correction rule is, for example, a rule for increasing the display brightness or the character size by "n" steps when the illuminance in the room is "m" lux or less. The set value correction unit 805 corrects at least one of the brightness and the character size of the display based on the indoor illuminance measured by the illuminometer according to the sixth correction rule. The device control unit 806 controls the work PC 7 based on the brightness and character size of the display corrected by the set value correction unit 805.
The work PC 7 is not necessarily limited to the stationary information processing device, and may be a portable information processing device.
