[0022] Hereinafter, examples of embodiments for carrying out the present invention will be described in detail with reference to the drawings. In this embodiment, an example of an embodiment in which the present invention is applied to a spatial evaluation support system that includes a wearable terminal and a mobile terminal used by each target person, a spatial evaluation support device, and an information storage device for storing various types of information will be described. Furthermore, in this embodiment, an example of an embodiment in which the target domain of the present invention is a residential building with multiple floors will be described.

[0023] First, the configuration of the spatial evaluation support system 1 according to this embodiment will be described with reference to Figure 1. Figure 1 is a block diagram showing an example of the configuration of the spatial evaluation support system 1 according to this embodiment.

[0024] As shown in Figure 1, the spatial evaluation support system 1 according to this embodiment includes a spatial evaluation support device 10, which plays a central role in the system, a wearable terminal 70, a mobile terminal 80, and an information storage device 90. The spatial evaluation support device 10 according to this embodiment acquires biometric information of a subject wearing the wearable terminal 70, and biometric information detected by the wearable terminal 70, via the mobile terminal 80 held by the subject. The spatial evaluation support device 10 then performs various processes using the biometric information acquired from the wearable terminal 70. The information storage device 90 according to this embodiment stores various types of information handled by the spatial evaluation support system 1.

[0025] As described above, in this embodiment, the biometric information detected by the wearable terminal 70 is transmitted to the spatial evaluation support device 10 via the mobile terminal 80, but this is not the only configuration. For example, the biometric information may be transmitted directly from the wearable terminal 70 to the spatial evaluation support device 10 without going through the mobile terminal 80.

[0026] On the other hand, the information storage device 90 according to this embodiment includes a non-volatile storage unit 92. The storage unit 92 is implemented by an HDD (Hard Disk Drive), SSD (Solid State Drive), flash memory, etc. The storage unit 92, as a storage medium, stores a biological information-related information database 92A and a spatial information-related information database 92B. The biological information-related information database 92A and the spatial information-related information database 92B will be described in detail later.

[0027] The spatial evaluation support device 10 and the information storage device 90 are connected via a network N, and the spatial evaluation support device 10 is capable of communicating with the information storage device 90 via the network N. In this embodiment, a corporate communication line such as a LAN (Local Area Network) or WAN (Wide Area Network) is used as the network N, but the embodiment is not limited to this configuration. For example, a public communication line such as the internet or a telephone line may be used as the network N, or a combination of these corporate communication lines and public communication lines may be used. Furthermore, in this embodiment, a wired communication line is used as the network N, but the embodiment is not limited to this configuration; a wireless communication line may be used, or a combination of wired and wireless communication lines may be used.

[0028] Next, the hardware configuration of the spatial evaluation support device 10 according to this embodiment will be described with reference to Figure 2. Figure 2 is a block diagram showing an example of the hardware configuration of the spatial evaluation support device 10 according to this embodiment. Examples of the spatial evaluation support device 10 include various computers such as personal computers and server computers.

[0029] The spatial evaluation support device 10 according to this embodiment includes a CPU (Central Processing Unit) 11, a memory 12 as a temporary storage area, a non-volatile storage unit 13, an input unit 14 such as a keyboard and mouse, a display unit 15 such as a liquid crystal display, a media read / write (R / W) device 16, and a communication interface (I / F) unit 18. The CPU 11, memory 12, storage unit 13, input unit 14, display unit 15, media read / write device 16, and communication I / F unit 18 are connected to each other via bus B. The media read / write device 16 reads information written to the recording medium 17 and writes information to the recording medium 17. The display unit 15 may be configured separately from the spatial evaluation support device 10 and made available for use in remote locations.

[0030] The storage unit 13 is implemented by an HDD, SSD, flash memory, etc. The storage unit 13, as a storage medium, stores the spatial evaluation support program 13A. The spatial evaluation support program 13A is stored (installed) in the storage unit 13 when the recording medium 17 on which the program 13A is written is set in the media read / write device 16, and the media read / write device 16 reads the program 13A from the recording medium 17. The CPU 11 sequentially reads the spatial evaluation support program 13A from the storage unit 13, loads it into memory 12, and sequentially executes the processes that the spatial evaluation support program 13A has.

[0031] Although not shown in the diagram to avoid confusion, in the spatial evaluation support system 1 according to this embodiment, a wearable terminal 70 and a mobile terminal 80 are provided for each target person that the spatial evaluation support system 1 is targeting.

[0032] Next, with reference to Figure 3, the functional configuration of the spatial evaluation support device 10 according to this embodiment will be described. Figure 3 is a block diagram showing an example of the functional configuration of the spatial evaluation support device 10 according to this embodiment.

[0033] As shown in Figure 3, the spatial evaluation support device 10 includes an acquisition unit 11A, a specific unit 11B, a derivation unit 11C, a presentation unit 11D, and a registration unit 11E. The CPU 11 of the spatial evaluation support device 10 executes the spatial evaluation support program 13A, which enables the acquisition unit 11A, specific unit 11B, derivation unit 11C, presentation unit 11D, and registration unit 11E to function.

[0034] The acquisition unit 11A according to this embodiment acquires location information indicating the position of a subject in the target area and biometric information indicating the biological physical quantities of the subject.

[0035] In this embodiment, as a method for acquiring the above-mentioned location information, each subject's mobile terminal 80 is equipped with a medium capable of short-range communication, such as an RFID (Radio Frequency Identification) tag, and capable of transmitting the identification information of the corresponding subject (in this embodiment, the subject ID described later). The method of acquiring the above-mentioned location information is applied by using this medium and via the mobile terminal 80.

[0036] However, the method for acquiring the above-mentioned location information is not limited to the method using the above-mentioned medium. For example, cameras may be installed throughout the entire target area to prevent blind spots, and the location information may be acquired using images obtained from these cameras. More specifically, each subject may be identified individually by image recognition (for example, pattern matching) using the images obtained from the above-mentioned cameras, and location information indicating the position of each subject in the image may be acquired as the above-mentioned location information. Alternatively, the location of the subject may be detected using beacons. Furthermore, a form using GPS (Global Positioning System) or an infrastructure-free positioning system (a system in which the application program of a mobile terminal captures and learns the geomagnetic field and other radio wave environments, enabling positioning without the need to install special equipment such as beacons in the target area) may also be used.

[0037] Furthermore, in this embodiment, a three-dimensional position is applied as the position of each subject indicated by the above position information, but this is not the only option. For example, if the target area is a single-story building or an outdoor facility located on flat ground, a two-dimensional position excluding the height direction may be applied as the position of each subject.

[0038] Furthermore, in this embodiment, as described above, the wearable terminal 70 is used to detect the subject's biometric information. More specifically, the wearable terminal 70 in this embodiment uses a wristband-type heart rate monitor, and the wearer's stress level is obtained as biometric information using autonomic nervous system activity estimated from the fluctuations in heart rate measured by the heart rate monitor. However, this is not the only form; the wearer's concentration level may also be obtained as biometric information using the autonomic nervous system activity. Alternatively, a headset-type electroencephalogram (EEG) measuring device may be used as the wearable terminal 70, and the wearer's relaxation level and concentration level may be obtained as biometric information by applying the Russell circumplexus model using the fluctuations in the EEG. Furthermore, combinations of two or all three of these stress levels, concentration levels, and relaxation levels may be obtained as biometric information. In addition, the wearable terminal 70 may be not limited to the wristband-type or headset-type devices described above, but may also be a glasses-type device, for example.

[0039] On the other hand, the identification unit 11B according to this embodiment uses the location information acquired by the acquisition unit 11A to identify spatial information that indicates the local spatial characteristics at the location indicated by the location information.

[0040] In this embodiment, both the ceiling height and the green view ratio of the target area are applied as spatial information, but this is not the only way to apply it. It is also possible to apply only one of the ceiling height or the green view ratio as spatial information. Furthermore, while the ceiling height and the green view ratio are examples of information that represent the openness of a space, the spatial information is not limited to information that represents the openness of a space. For example, it is also possible to apply information that represents the specifications of furniture and fixtures installed in the target area, information that represents comfort in terms of light, heat, and noise, or the color distribution of the landscape as spatial information.

[0041] Furthermore, the derivation unit 11C according to this embodiment uses the spatial information identified by the identification unit 11B and the corresponding biological information to derive related information that shows the relationship between the local spatial characteristics in the target region and the biological physical quantities indicated by the corresponding biological information.

[0042] In this embodiment, the related information used is information indicating the ratio of the number of biological information detected for multiple subjects that falls within a predetermined appropriate range for each type of spatial information, relative to the total number (hereinafter referred to as "appropriateness"). However, this is not the only form of related information. For example, the related information may be a graph with biological information on the horizontal axis and spatial information on the vertical axis, where the values ​​of the biological information detected for multiple subjects are plotted at positions corresponding to the spatial information values ​​at the locations where the biological information was detected.

[0043] The display unit 11D according to this embodiment then displays the relevant information derived by the derivation unit 11C.

[0044] In this embodiment, the presentation of various information by the presentation unit 11D is shown by display by the display unit 15, etc., but it is not limited to this. For example, the presentation by the presentation unit 11D may be shown by sound from an audio playback device such as a speaker, or the presentation by the presentation unit 11D may be shown by printing from an image forming device such as a printer.

[0045] On the other hand, the registration unit 11E according to this embodiment registers the location information and biometric information acquired by the acquisition unit 11A in association with each other. The presentation unit 11D according to this embodiment then further presents the biometric information registered by the registration unit 11E in a two-dimensional manner as being located at the position indicated by the corresponding location information.

[0046] In this embodiment, the two-dimensional presentation of biometric information by the presentation unit 11D involves displaying the floor with the largest number of subjects in the target building as a floor plan, and displaying marks representing subjects and their biometric information at corresponding positions on the floor plan. However, it goes without saying that the presentation is not limited to this form. Furthermore, the method of presenting biometric information is not limited to the two-dimensional presentation method described above, but may also be a three-dimensional presentation method that includes the height direction. In this case, even if the target building has multiple floors, the biometric information for those multiple floors can be displayed as a single image.

[0047] Next, with reference to Figure 4, the biometric information-related information database 92A according to this embodiment will be described. Figure 4 is a schematic diagram showing an example of the configuration of the biometric information-related information database 92A according to this embodiment. The biometric information-related information database 92A according to this embodiment is for storing information about the biometric information of each subject.

[0048] As shown in Figure 4, the biometric information-related information database 92A according to this embodiment stores the following information in association with each other: target area ID (Identification), target person ID, attributes, date and time, location information, and biometric information.

[0049] The above-mentioned target area ID is information pre-assigned as unique information to each target area in order to individually identify the corresponding target area, and the above-mentioned subject ID is information pre-assigned as unique information to each subject in order to individually identify the corresponding subject. Furthermore, the above-mentioned attributes are information indicating the attributes of the corresponding subject, the above-mentioned date and time are information indicating the date and time, and the above-mentioned location information is information indicating the location where the corresponding subject was at the corresponding date and time. In addition, the above-mentioned biometric information is information indicating the biometric information of the corresponding subject at the corresponding date and time.

[0050] In this embodiment, as shown in Figure 4, location information and biometric information are registered in the biometric information-related information database 92A every second, but this is not limited to this. For example, location information and biometric information may be registered in the biometric information-related information database 92A at intervals of less than one second, such as every 0.1 seconds or every 0.5 seconds. Furthermore, location information and biometric information may be registered in the biometric information-related information database 92A at intervals longer than one second, such as every 5 seconds or every 10 seconds. In addition, in this embodiment, information indicating gender is used as information indicating the above attributes, but this is not limited to this. For example, other attributes such as age group, residential area, personnel information (job title, job function, etc.), or additional attribute information obtained from personality tests, etc., may be used as information indicating the above attributes.

[0051] Next, with reference to Figure 5, the spatial information-related information database 92B according to this embodiment will be described. Figure 5 is a schematic diagram showing an example of the configuration of the spatial information-related information database 92B according to this embodiment. The spatial information-related information database 92B according to this embodiment is for storing information related to the spatial information of each target area.

[0052] As shown in Figure 5, the spatial information-related information database 92B according to this embodiment stores the target area ID, 3D building information, sectioned area name, sectioned area location, and spatial information in association with each other.

[0053] The above target area ID is the same information as the target area ID in the biometric information-related information database 92A, and the above 3D building information is 3D CAD (Computer Aided Design) information of a building constructed in the corresponding target area (hereinafter referred to as "target building"). In this embodiment, the 3D building information is created using 3D CAD software, but it is not limited to this. For example, the 3D building information may be created using BIM (Building Information Modeling) software.

[0054] Furthermore, the above-mentioned division area names are information indicating the names of each division area, which are created by dividing the corresponding target building according to predetermined conditions. In this embodiment, the predetermined conditions are those for individual rooms such as entrances, meeting rooms, and living rooms, but this is not the only option. For example, the target building may be divided into four areas (east, west, north, and south) centered on the location of the center of the plan view, and the conditions for combinations of rooms included in each division area may be applied as the predetermined conditions.

[0055] Furthermore, the above-mentioned partitioned area position is information indicating the three-dimensional position of the partitioned area (in this embodiment, a room) indicated by the corresponding partitioned area name. In this embodiment, in order to avoid confusion, each partitioned area is assumed to be a rectangular parallelepiped, and information indicating the three-dimensional positions of a pair of diagonal corners of the rectangular parallelepiped is applied as information indicating the above-mentioned partitioned area position; however, it goes without saying that this is not the only way to do so.

[0056] Furthermore, the spatial information described above includes information indicating the ceiling height and green view ratio within the corresponding partitioned area. Here, "green view ratio" refers to information indicating the proportion of natural greenery visible within the field of vision in the corresponding space.

[0057] Next, with reference to Figures 6 to 10, the operation of the spatial evaluation support device 10 according to this embodiment during the execution of the spatial evaluation support process will be explained. Figure 6 is a flowchart showing an example of the spatial evaluation support process according to this embodiment.

[0058] The spatial evaluation support process shown in Figure 6 is executed when the CPU 11 of the spatial evaluation support device 10 executes the spatial evaluation support program 13A. The spatial evaluation support process shown in Figure 6 is executed when a user of the spatial evaluation support device 10 (in this embodiment, the administrator of the spatial evaluation support system 1) issues an instruction to start the execution of the spatial evaluation support program 13A via the input unit 14. To avoid confusion, the following description assumes that the spatial information-related information database 92B has already been constructed and that the target area ID, target person ID, and attribute information in the biometric information-related information database 92A have already been registered. Furthermore, to avoid confusion, the following description assumes that information indicating the appropriate range for each type of spatial information in the biometric information described above has been set in advance.

[0059] In step 100 of Figure 6, the CPU 11 controls the display unit 15 to display an initial information input screen with a predetermined configuration, and in step 102, the CPU 11 waits until predetermined information is entered.

[0060] Figure 7 shows an example of the configuration of the initial information input screen according to this embodiment. As shown in Figure 7, the initial information input screen according to this embodiment displays a message prompting the user to specify the target area to be processed. In addition, the initial information input screen according to this embodiment displays an input area 15A for inputting information that can identify the target area to be processed (in this embodiment, the target area ID).

[0061] As an example, when the initial information input screen shown in Figure 7 is displayed on the display unit 15, the user uses the input unit 14 to input the target area ID corresponding to the target area to be processed (hereinafter referred to as the "processing target area") into the input area 15A, and then selects the exit button 15C displayed on the screen. When the user selects the exit button 15C, step 102 becomes a positive result and proceeds to step 104.

[0062] In step 104, the CPU 11 reads 3D building information, section name, section location, and spatial information (hereinafter referred to as "spatial information-related information") corresponding to the target area ID entered by the user from the spatial information-related information database 92B. In step 106, the CPU 11 uses the read spatial information-related information to control the display unit 15 to start displaying a biometric information presentation screen with a predetermined configuration.

[0063] Figure 8 shows an example of the configuration of the biometric information display screen according to this embodiment. As shown in Figure 8, the biometric information display screen according to this embodiment displays a floor plan of the building located in the processing target area (in this embodiment, a floor plan of the floor with the most subjects). 15B

[0064] In this embodiment of the spatial evaluation support system 1, an unspecified number of subjects wear a wearable terminal 70 and carry a mobile terminal 80, and walk or stand still inside a building (hereinafter referred to as the "processing target building") located in the processing target area. Accordingly, biometric information (stress level in this embodiment) detected by the wearable terminal 70 is transmitted to the spatial evaluation support device 10 via the mobile terminal 80 at predetermined intervals (1 second in this embodiment). At this time, the mobile terminal 80 transmits the biometric information to the spatial evaluation support device 10 along with location information indicating its own position and information that can identify the subject (subject ID in this embodiment), obtained by the aforementioned medium.

[0065] Therefore, in step 108, the CPU 11 waits until location information and biometric information are received. In step 110, the CPU 11 determines whether the received location information and biometric information should be adopted. If the determination is negative, the system proceeds to step 118; if the determination is positive, the system proceeds to step 112.

[0066] In this embodiment, the information to be adopted is limited to cases where the location indicated by the received location information is within a space that is not to be used for spatial evaluation, such as toilets and corridors in the building being processed. However, this is not the only option. For example, the information to be adopted may be limited to cases where the information to be adopted is limited to cases where the location indicated by the received location information is within a space that is not to be used for spatial evaluation, such as toilets and corridors in the building being processed. Alternatively, the information to be adopted may be limited to cases where there are no problems with the reliability of biometric information or location information, such as cases where the signal-to-noise ratio of the received signal from the mobile terminal 80 is above a predetermined value.

[0067] In step 112, the CPU 11 updates the biometric information display screen shown on the display unit 15 using the received location information, biometric information, and subject ID. Specifically, the CPU 11 displays a predetermined mark (a star-shaped mark in this embodiment) at the location indicated by the received location information, and displays the received biometric information (stress level in this embodiment) and the received subject ID near the mark.

[0068] Figure 9 shows an example of the configuration of the biometric information display screen according to this embodiment at this point in time. As shown in Figure 9, this biometric information display screen displays a mark indicating the subject's location, the subject's biometric information, and the subject's ID. Therefore, by referring to the biometric information display screen, the user can understand who the subject is, as well as easily grasp the subject's location and biometric information. Furthermore, by referring to the biometric information display screen, the user can immediately determine whether the location information and biometric information are valid or not.

[0069] As an example, as shown in Figure 9, when the biometric information display screen is updated, the user uses the input unit 14 to select the NG button 15D if there is a problem with the newly displayed information.

[0070] Therefore, in step 114, the CPU 11 determines whether the newly displayed information is valid by checking whether the NG button 15D has been selected. If the result is negative, the system proceeds to step 118; if the result is positive, the system proceeds to step 116.

[0071] In step 116, the CPU 11 stores (registers) the newly displayed location information and biometric information on the biometric information display screen, along with information indicating the date and time at that time, in chronological order as information corresponding to the received subject ID in the biometric information related information database 92A.

[0072] In step 118, the CPU 11 determines whether the number of registered location information and biometric information corresponding to the processing area in the biometric information-related information database 92A has reached a predetermined number. If the determination is negative, the process returns to step 108; if the determination is positive, the process proceeds to step 120. In this embodiment, the predetermined number is set to a number (10,000 sets in this embodiment) that allows the aforementioned related information to be derived in a way that satisfies the required accuracy, but it goes without saying that this is not the only predetermined number.

[0073] In step 120, the CPU 11 reads all subject IDs, attributes, location information, and biometric information (hereinafter referred to as "biometric information-related information") corresponding to the processing area from the biometric information-related information database 92A, and in step 122, the CPU 11 executes the related information derivation process to derive the above-mentioned related information using the read spatial information-related information and biometric information-related information as follows.

[0074] Specifically, first, the CPU 11 classifies the biological information (stress level in this embodiment) contained in the biological information-related information according to the attributes contained in the biological information-related information and according to the divisional region indicated by the divisional region position contained in the spatial information-related information.

[0075] The CPU 11 then calculates the appropriateness level described above as a percentage for each attribute and each classification area, and includes it as related information. The appropriateness level calculated here indicates the degree to which the subject's biological information for each attribute was in an appropriate state within the corresponding classification area.

[0076] In step 124, the CPU 11 controls the display unit 15 to display a predetermined related information presentation screen using the derived related information, and in step 126, the CPU 11 waits until predetermined information is input.

[0077] Figure 10 shows an example of the configuration of the related information display screen according to this embodiment. As shown in Figure 10, in the related information display screen according to this embodiment, related information (in this embodiment, the appropriateness of biological information (stress level) for each divided area and for each spatial information (ceiling height and green view ratio)) is displayed for each corresponding attribute (in this embodiment, gender). Therefore, by referring to the related information display screen, the user can grasp the related information in detail, and as a result, can perform a more accurate spatial evaluation of the target area.

[0078] For example, when the related information display screen shown in Figure 10 is displayed on the display unit 15, the user understands the displayed content and then uses the input unit 14 to select the exit button 15C. When the user selects the exit button 15C, step 126 becomes a positive determination and the spatial evaluation support process ends.

[0079] As described above, according to this embodiment, location information indicating the position of a subject in the target area and biometric information indicating the biological physical quantities of the subject are acquired. Using the acquired location information, spatial information indicating the local spatial characteristics at the location indicated by the location information is identified. Using the identified spatial information and the corresponding biometric information, related information indicating the relationship between the local spatial characteristics in the target area and the biological physical quantities indicated by the corresponding biometric information is derived, and the derived related information is presented. Therefore, compared to cases where local spatial information is not considered, a more accurate spatial evaluation of the target area can be performed.

[0080] Furthermore, according to this embodiment, acquired location information and biometric information are registered in association, and the registered biometric information is further presented in two dimensions as being located at the position indicated by the corresponding location information. Therefore, the validity of the biometric information can be determined by referring to the presented biometric information.

[0081] Furthermore, according to this embodiment, the target area is defined as a human activity area (in this embodiment, a residential area). Therefore, it is possible to perform a more accurate spatial evaluation of a human activity area.

[0082] Furthermore, according to this embodiment, biological information is used as a stress level. Therefore, it is possible to perform a more accurate spatial evaluation of the target area in terms of stress level.

[0083] Furthermore, according to this embodiment, the spatial information includes ceiling height and green view ratio. Therefore, it is possible to more accurately evaluate the spatial characteristics of the target area with respect to this spatial information.

[0084] In the above embodiment, we described a case where an appropriateness score, which indicates the proportion of appropriate biological information for each divided region, is applied as related information, but this is not the only case. For example, it is also possible to apply information as related information that displays divided regions with an appropriateness score above a predetermined lower limit as appropriate regions, and other regions as inappropriate regions. Furthermore, it is also possible to display information that recommends spatial information of appropriate divided regions as an alternative to the spatial information of inappropriate divided regions.

[0085] Furthermore, although the above embodiment describes a case in which the spatial evaluation support device of the present invention is configured using the spatial evaluation support device 10 and the information storage device 90, it is not limited to this. For example, the spatial evaluation support device of the present invention may be configured as a single device that integrates the spatial evaluation support device 10 and the information storage device 90. Moreover, the spatial evaluation support device of the present invention may be configured using multiple computers, and the spatial evaluation support processing may be distributed among these multiple computers.

[0086] Furthermore, while the above embodiment described a case where related information is derived for each attribute, it is not limited to this. For example, related information may be derived for each time of day, such as morning, noon, and night, or for each period, such as month or season.

[0087] Furthermore, while the above embodiment describes the case where the biometric information display screen shown in Figure 9 is applied, it is not limited to this. For example, instead of the one shown in Figure 9, a screen that displays information obtained by averaging biometric information from multiple subjects as a heat map in two dimensions on a drawing may be applied as the biometric information display screen. Alternatively, the biometric information display screen may display biometric information and location information registered in the biometric information-related information database 92A in a list format. In this case, instead of displaying all registered information, it is also possible to display information only for specific users (for example, users with pre-specified attributes).

[0088] Furthermore, in the above embodiment, for example, the hardware structure of the processing unit that executes the acquisition unit 11A, the identification unit 11B, the derivation unit 11C, the presentation unit 11D, and the registration unit 11E can be any of the following types of processors. As mentioned above, these types of processors include a CPU, which is a general-purpose processor that executes software (programs) and functions as a processing unit, as well as a programmable logic device (PLD), such as an FPGA (Field-Programmable Gate Array), which is a processor whose circuit configuration can be changed after manufacturing, and a dedicated electrical circuit, such as an ASIC (Application Specific Integrated Circuit), which is a processor with a circuit configuration specifically designed to execute a particular process.

[0089] The processing unit may consist of one of these various processors, or it may consist of a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Alternatively, the processing unit may consist of a single processor.

[0090] Examples of configuring a processing unit with a single processor include, firstly, a configuration where one or more CPUs and software combine to form a single processor, as is common in client and server computers, and this processor functions as the processing unit. Secondly, a configuration using a processor that realizes the functions of the entire system, including the processing unit, on a single IC (Integrated Circuit) chip, as is common in System-on-a-Chip (SoC) systems. Thus, the processing unit is configured, in terms of hardware structure, using one or more of the above-mentioned types of processors.

[0091] Furthermore, the hardware structure of these various processors can more specifically utilize electrical circuits, which are combinations of circuit elements such as semiconductor devices. [Explanation of symbols]
