[Technical Field]

[0001] The present invention relates to an electronic device, an information display method, and a program. [Background technology]

[0002] Exercise support devices have been developed that analyze exercise data when a user exercises, such as running or walking, and output advice to the user.

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-5766 Summary of the Invention [Problem to be solved by the invention]

[0004] The running support system disclosed in Patent Document 1 uses machine learning to create a numerical model based on the user's exercise data during exercise, and by inputting new exercise data into this numerical model, calculates and displays the factor contribution rate, etc. This allows the user to see the factors that had the greatest impact on the current exercise, i.e., the key points for improving the level. However, because the information displayed is diverse, it is difficult for the user to quickly grasp the necessary information.

[0009] Electronic devices and the like according to embodiments will be described with reference to the drawings. Note that the same or corresponding parts in the drawings are designated by the same reference numerals. The electronic device 100 according to the embodiment is a wearable device that is worn by a user when exercising. The position at which the electronic device 100 is worn varies depending on the type of electronic device 100. Generally, a waist-mounted type is desirable when emphasis is placed on the accuracy of measuring exercise data, and a wrist-mounted type is desirable when emphasis is placed on the readability of displayed information. The electronic device 100 analyzes the user's exercise data, obtains values ​​of various indices, and calculates a score that evaluates the user's exercise based on these values. The electronic device 100 then notifies the user of which indices need to be improved to efficiently improve the score. This operation of the electronic device 100 will be described later.

[0010] As shown in FIG. 1, the electronic device 100 includes, as its functional configuration, a control unit 110, a storage unit 120, a measurement unit 130, a display unit 140, an operation input unit 150, and an audio output unit 160. The control unit 110 is configured with a processor such as a CPU (Central Processing Unit), etc. The control unit 110 executes processes for realizing various functions of the electronic device 100, index extraction processing and index display processing, which will be described later, using programs stored in the storage unit 120. The storage unit 120 stores programs executed by the control unit 110 and necessary data (for example, measurement results measured by the measurement unit 130). The storage unit 120 may include, but is not limited to, a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, etc. Note that the storage unit 120 may be provided inside the control unit 110.

[0011] The measurement unit 130 includes devices that measure various values ​​related to the user's exercise (running, walking, etc.), such as an acceleration sensor, a gyro sensor, a GPS (Global Positioning System) device, a heart rate sensor, a temperature sensor, and an air pressure sensor. The control unit 110 acquires values ​​(measured values) measured by each device included in the measurement unit 130 and can derive index values ​​for each of various indices related to the user's exercise. The control unit 110 functions as an acquisition unit when acquiring the measurement results measured by the measurement unit 130. Note that the measurement unit 130 does not necessarily need to include all of the above sensors, and may not include some sensors (for example, a heart rate sensor, a temperature sensor, or an air pressure sensor) as long as there is no problem in deriving the indices related to the user's exercise.

[0012] The control unit 110 stores various measurement values ​​measured by the measurement unit 130, various index values ​​derived based on these measurement values, and various scores derived based on these index values ​​in the storage unit 120 as exercise log data. The indexes indicate various types of measures for evaluating a user's exercise (e.g., running), such as pace (time required to run 1 km), pitch (number of steps per minute), stride (distance of one step from one touchdown to the next), and landing impact (magnitude of impact on the body immediately after landing), as shown in FIG. 2 . Some indexes are directly derived from the measurement values ​​(measurement results) measured by the measurement unit 130, while others are derived from multiple measurement values. Some of these indexes (e.g., "pace") may be used to determine target values ​​(target values) for other indexes.

[0013] Display unit 140 includes a display such as a liquid crystal display, an organic EL (Electro-Luminescence) display, etc. Display unit 140 displays information based on the measurement by measurement unit 130 (various index values, form analysis results, etc.). Operation input unit 150 is a user interface such as a push button switch or a touch panel, and accepts operation input from the user. When operation input unit 150 includes a touch panel, it may be a touch panel integrated with the display of display unit 140. In this embodiment, operation input unit 150 includes, as push button switches, an exercise start button 151 for notifying electronic device 100 that the user is about to start exercising, an exercise end button 152 for notifying electronic device 100 that the user is about to end exercising, and the like, as shown in FIG. Audio output unit 160 includes audio output means such as a speaker or earphones, and outputs audio announcements, notification sounds, sound effects, etc. Note that an exercise start button 151, an exercise end button 152, etc. may be provided as operation input unit 150 near the earphones. Furthermore, if output of audio announcements, notification sounds, etc. is not required, electronic device 100 does not need to include audio output unit 160.

[0014] The functional configuration of electronic device 100 has been described above. Control unit 110 analyzes the user's form based on the measurements (user's exercise data) taken by measurement unit 130, and displays radar charts 141 and 142 based on various evaluation items (six evaluation items in this figure: "whole-body exercise centered on the pelvis," "low-stress ground contact," "powerful exercise," "stable posture," "smooth center of gravity movement," and "bilateral symmetry"), as well as an overall score 143, as shown in FIG. 3. Each evaluation item making up radar charts 141 and 142 is assigned a related index (related index), and the score of the evaluation item (evaluation item score) is calculated by weighting and adding the score of the related index (related index score) derived from the index value of the related index. Radar charts 141 and 142 are then drawn based on the evaluation item scores. Then, the overall score 143 is calculated by weighting and adding each evaluation item score according to the purpose of the exercise (purpose of running). However, the above-mentioned method of calculating the evaluation item scores and the overall score 143 is merely an example, and these scores may be calculated by other methods.

[0015] The method for deriving each index score is also arbitrary, but several methods will be described below. For example, the first method is to refer to a predefined table. This is a method of deriving an index score for an index based on the index value by referring to a table (index score definition table) that defines information such as "if the index value is greater than or equal to x and less than y, the score is z points" for each index for each user's profile information (especially the value of the index "pace"). The second method is to refer to a simpler table. This method finds the reference value for each index by referencing a table (index reference value table) that sets ideal reference values ​​(the range of index values ​​that will result in a perfect score (e.g., 100 points)) for each index for each user's pace value, and then deducts points based on how far the index value deviates from this reference value to derive the index score for that index. A third method is to use a formula to calculate the ideal standard value (the range of index values ​​that will result in a perfect score) for each index for each user's pace value without using a table, and then deduct points from the score based on how far the index value deviates from this standard value to derive the index score for that index. Although three methods for deriving index scores have been given above, the method for deriving index scores is not limited to the methods given here.

[0016] 3 shows not only radar chart 141 based on the form from the previous exercise, but also radar chart 142 based on the target form (the form when running in the desired manner). This radar chart 142 is determined by the evaluation item scores calculated from the index scores obtained when the values ​​of each index are improved according to the purpose of exercise (purpose of running).

[0017] As described above, the total score 143 is calculated by weighting and adding the scores of each evaluation item according to the purpose of exercise (purpose of running). This purpose of exercise (purpose of running) is set by the user when using the electronic device 100, and represents what the user wants to achieve by exercising (running), such as "I want to run faster," "I want to run longer," "I want to run for health," or "I want to run comfortably." Once the user sets the purpose of exercise, it is desirable to provide the user with information on which indicators should be improved to achieve that purpose. Therefore, the storage unit 120 pre-stores information in the form of a recommended index candidate table, in which each objective is linked to candidates for indicators (recommended indexes for improvement) to be improved for that objective. Information on which evaluation item scores should be paid attention to for the set objective is also useful for the user. Therefore, the storage unit 120 may pre-store information in the form of a recommended evaluation item table in which each objective is linked to evaluation items that should be paid attention to for that objective (recommended evaluation items for attention). In this embodiment, the storage unit 120 is assumed to store a recommended index candidate table for improvement and a recommended evaluation item table for attention.

[0018] For example, if the purpose of running is "I want to run for health," preventing injuries is important, so the index values ​​of "landing impact," "kick-off acceleration," and "vertical dynamic height ratio" should each be small to reduce the strain on the knees. Therefore, the recommended indicator candidates for improvement linked to the purpose of "I want to run for health" are "landing impact," "kick-off acceleration," "vertical dynamic height ratio," etc. (These are stored in a recommended indicator candidate table for improvement). Then, in the indicator extraction process described below, the indicator that is thought to contribute most to improving the score is extracted from these recommended indicator candidates for improvement. Similarly, in this case, since "low-impact landing" should be emphasized among the evaluation items of the radar chart 141, "low-impact landing" is linked to and stored as an evaluation item in the recommended evaluation item table for the purpose of "I want to run for health."

[0019] As can be seen from the above explanation, the recommended index candidates for improvement and the recommended evaluation items for attention vary depending on the purpose of running. For example, to explain another example of a recommended index candidate for improvement, if the purpose is "to run faster," then the "stride-to-height ratio" should be increased, so the recommended index candidate for improvement would be "stride-to-height ratio." Furthermore, if the purpose is "to run longer," then the "kick-off acceleration" should be decreased, so the recommended index candidate for improvement would be "kick-off acceleration." Furthermore, as mentioned here, among the indexes to be improved, some should be increased and some should be decreased (and some should be within a certain range). Therefore, the table of recommended index candidates for improvement may also store the type of such index (e.g., should be increased, should be decreased, should be within a specified range), and a mark indicating the type may be displayed. For example, a "larger index is better," a "-" is displayed for a "smaller index is better," and an "=" is displayed for a "index that should be within a certain range." The "+" in the "stride-to-height ratio+" display frame 146 in FIG. 3 indicates that the "larger stride-to-height ratio is better." In the example described here, only one candidate recommended indicator for improvement is presented for each objective, but this is just an example, and the candidate recommended indicator for improvement is not limited to one indicator.

[0020] When form analysis is performed after the user has exercised, the control unit 110 sets target values ​​for each index based on the user's profile information (height, weight, sex, pace, etc.) and exercise log data. The target values ​​may be set by referring to a table (target value setting table) created in advance by collecting information such as "if you exercise at this pace, you should aim for about this value," or by calculating values ​​that the user is likely to be able to achieve reasonably based on the exercise log data up to that point.

[0021] For example, Fig. 3 is a display example in which "run fast" is set as the running purpose, as shown in display frame 144. Display frame 146 displays "stride-to-height ratio" as an index recommended for improvement, which is extracted in the index extraction process described below. Display frame 145 displays "power of movement" as an evaluation item recommended for attention, which is acquired by referring to the table of evaluation items recommended for attention. Fig. 3 also shows that the previous index value is 0.58 and the target value is 0.61 in display frame 146, and that the previous score was 6 and the target score was 7 in display frame 145. This means that the index value for "stride-to-height ratio" during the previous exercise was 0.58, the evaluation item score for "power of movement" derived based on related indices including this index value was 6, the target value for "stride-to-height ratio" based on the user's previous pace was 0.61, and if the index value for "stride-to-height ratio" is increased from 0.58 to 0.61 during the next exercise, the evaluation item score for "power of movement" will rise to 7. Figure 3 also shows that the total score 143 is 62 and the target score is 64, which means that if the index value for "stride-to-height ratio" is increased to 0.61, the evaluation item score for "power of movement" will rise to 7, and accordingly the total score 143 will improve from 62 to the target score of 64.

[0022] The index extraction process, which is a process for extracting recommended improvement indices based on past exercise data, will be described with reference to Fig. 4. This process can be executed at any timing, but is usually executed after the user has exercised while wearing electronic device 100.

[0023] First, the control unit 110 determines whether past exercise data is stored in the storage unit 120 (step S101). If past exercise data is not stored (step S101; No), the process returns to step S101. If past exercise data is stored (step S101; Yes), the control unit 110 performs form analysis based on the previous exercise data (step S102). In this step, the control unit 110 derives an index score for each index based on the index values ​​from the previous exercise stored in the storage unit 120 as exercise log data. The control unit 110 calculates an evaluation item score for each evaluation item by weighting and adding the index scores of related indexes for each of the multiple evaluation items used to create the radar chart 141. The control unit 110 also calculates a total score 143 by weighting and adding the evaluation item scores for each evaluation item according to the user's running purpose. The control unit 110 also calculates a target value for each index based on the past exercise data, and adds and saves the acquired or calculated index values, target values, and scores to the exercise log data in the storage unit 120.

[0024] The control unit 110 then extracts recommended indicators for improvement (step S103) and terminates the indicator extraction process. In step S103, the control unit 110 first acquires recommended indicator candidates for improvement based on the recommended indicator candidate table stored in the storage unit 120 and the user's running purpose, and extracts a predetermined number of indicators that are thought to contribute to improving the overall score 143 from these recommended indicator candidates as recommended indicators for improvement. The recommended indicator for improvement extracted here is not limited to just one indicator that is thought to contribute the most, but a predetermined number of indicators may be selected in descending order of contribution and extracted as recommended indicators for improvement. The number of recommended indicators to be extracted is arbitrary and may be freely changed to, for example, a number desired by the user. Any method may be used to extract recommended indicators for improvement, which are indicators that are thought to contribute to improving the score, from the recommended indicator candidate candidates for improvement; several methods will be described below.

[0025] For example, as a first method, the control unit 110 refers to the exercise log data stored in the storage unit 120 for each of the indices included in the candidate indexes recommended for improvement, calculates the differential coefficient of the index score with respect to the value of the index during the previous exercise, and extracts the indices recommended for improvement in descending order of the differential coefficient. If the index score is a non-differentiable function, such as when an index score specification table is used in deriving the index score, the indices recommended for improvement may be extracted in descending order of the increase in the index value due to an increase in the index score (for example, an increase by 1). As a second method (which can be considered a variation of the first method), the control unit 110 refers to the exercise log data stored in the memory unit 120 to determine the standard deviation of each of the indices included in the candidate indices recommended for improvement, calculates the increase in the index score when a constant (for example, 0.1) times the standard deviation is added to or subtracted from the index value during the previous exercise, and extracts the indices recommended for improvement in descending order of the calculated increase in the index score. As a third method, the control unit 110 performs form analysis based on the exercise log data stored in the memory unit 120, sets target values ​​for each of the indicators included in the candidate recommended indicators for improvement, and extracts the indicators recommended for improvement in order of the largest difference between the set target value and the indicator value during the previous exercise. Note that the range of change in index values ​​varies greatly depending on the type of index, so in order to prevent this effect, rather than using the index values ​​directly, it is possible to normalize each index value using exercise log data, etc. One example of a method for normalizing an index value is to subtract the average value of the index from the index value and divide the result by the standard deviation of the index.

[0026] The control unit 110 executes the above-described index extraction process to extract a predetermined number of indexes recommended for improvement (e.g., a number set by the user). Furthermore, the index values, target values, and index scores of each index obtained as a result of form analysis, as well as the evaluation item scores and target scores of each evaluation item, are stored in the exercise log data. Therefore, the control unit 110 can display the extracted indexes recommended for improvement and their previous index values ​​and target values ​​on the display unit 140, as shown in a display frame 146 of FIG. 3. Furthermore, the control unit 110 can display the types of evaluation items recommended for attention and their previous scores and target scores on the display unit 140, as shown in a display frame 145 of FIG. 3, based on the recommended evaluation item table and exercise log data stored in the storage unit 120. The target score is the score obtained when the values ​​of the related indexes assigned to that evaluation item achieve their target values, and is calculated based on the target values ​​of each index stored in the exercise log data.

[0027] By looking at the screen shown in Figure 3, the user can see that they should try to increase their stride-to-height ratio the next time they run. However, even if they remember this when looking at this screen, they may forget it when they actually go running. Therefore, an indicator display process that allows the user to check the recommended indicators for improvement and whether or not the indicators have been improved while running will be described with reference to Fig. 5. This process can be executed at any time, but is typically executed immediately before the user starts exercising. For example, the process may be started by launching an app that executes the indicator display process when the user starts running.

[0028] First, the control unit 110 determines whether the user has started exercising (for example, running) (step S201). This determination is made by determining whether the exercise start button 151 has been pressed, but is not limited to this. For example, the determination may be made based on whether the measurement unit 130 or the like has detected that the user has started exercising. If the user has not started exercising (step S201; No), the process returns to step S201. If the user has started exercising (step S201; Yes), the control unit 110 determines whether an index recommended for improvement exists (step S202). If an index recommended for improvement has been extracted in the index extraction process described above, it means that an index recommended for improvement exists.

[0029] If there are indicators recommended for improvement (step S202; Yes), the control unit 110 displays the indicators recommended for improvement in a priority display area 147 of the display unit 140 (step S203), as shown in FIG. 6. The priority display area 147 is an area on the display unit 140 for displaying items that the user is to be given priority in viewing (an area where the displayed items are easy to see). By displaying the indicators recommended for improvement in the priority display area 147, the user can easily check which indicators to improve have a high priority, even while exercising. Furthermore, to clarify that the indicators displayed in the priority display area 147 are indicators recommended for improvement, the control unit 110 may display target values ​​for the indicators recommended for improvement together with the current index values ​​(current values), as shown in FIG. 6. Furthermore, as shown in FIG. 6, the priority display area 147 may be surrounded by a frame 148 to indicate that it is the priority display area 147.

[0030] In the example shown in Figure 6, two recommended indicators for improvement, "stride-to-height ratio" and "pelvic rotation," are displayed. By displaying the current and target values ​​for each indicator, users can easily understand how to change their form to improve each indicator. Furthermore, by displaying not only the target value but also the type of indicator (e.g., "increase (+)," "decrease (-)," or "keep within a specified range (=)") (in the example shown in Figure 6, a "+" indicates that a value greater than the target value would be better), users can more easily work to improve their scores. Note that while Figure 6 shows two recommended indicators for improvement, this number depends on the number of recommended indicators extracted in the indicator extraction process. Having one recommended indicator for improvement offers the advantage of allowing users to focus on improving that one indicator. Having multiple recommended indicators for improvement offers the advantage of allowing users to choose the indicator they think is easiest to improve from the multiple indicators and work on improving it.

[0031] Then, the control unit 110 determines whether the index recommended for improvement has improved or worsened compared to the index value at the previous exercise (step S204). In this step, the control unit 110 compares the index score of the index at the previous exercise with the current index score of the index, and determines that there has been an improvement if the current index score is higher than the previous index score, and determines that there has been a deterioration if the current index score is lower than the previous index score. Note that the determination criterion may have a predetermined range (for example, 10%), so that there is an improvement if the current index score is 10% or more higher than the previous index score, and there is a deterioration if the current index score is 10% or more lower. Furthermore, the size of this predetermined range may be different depending on whether there is an improvement or a deterioration.

[0032] If the index recommended for improvement has improved or worsened compared to the index value at the previous exercise (step S204; Yes), the control unit 110 changes the display mode of the index recommended for improvement (step S205) and proceeds to step S208. The control unit 110 may change the display mode in any way in step S205. For example, while index values ​​are normally (default) displayed in black, the improved index value of the index recommended for improvement may be displayed in red, and the worsened index value of the index recommended for improvement may be displayed in blue. Instead of (or in addition to) changing the color of the index value, the background color of the area where the index is displayed may be changed. Also, for example, as shown in FIG. 6, the improved index value of the index recommended for improvement may be displayed in bold font and underlined, and the worsened index value of the index recommended for improvement may be displayed in italic font. Note that in this embodiment, the improvement or deterioration is based solely on a comparison with the index value at the user's previous exercise and is unrelated to whether or not the target value has been achieved. However, even when the user achieves the target value, the control unit 110 may change the display mode of the index value that has achieved the target value, or output a sound effect (a sound notifying the user that the target value has been achieved) from the audio output unit 160, to make it easier for the user to understand that the target value has been achieved.

[0033] On the other hand, if it is determined in step S204 that the improvement recommendation index has neither improved nor worsened (step S204; No), the control unit 110 returns the display mode of the improvement recommendation index to the original (default setting) (step S206), and proceeds to step S208. In step S206, the control unit 110 returns the index value to being displayed in black, for example.

[0034] On the other hand, if it is determined in step S202 that no index recommended for improvement exists (step S202; No), the control unit 110 displays each index on the display unit 140 in the normal (default) order as shown in Fig. 7 (step S207), and proceeds to step S208. In this case, since no index recommended for improvement exists, various indexes are displayed in the normal order and normal display mode. The index display area 149 shown in Fig. 7 displays pitch, stride, ground contact time ratio, and stride-to-height ratio in the default display order.

[0035] In step S208, the control unit 110 determines whether the user has finished exercising (step S208). This determination is made by determining whether the exercise end button 152 has been pressed, but is not limited to this. For example, the determination may be made by determining whether the measurement unit 130 has detected that the user has finished exercising. If the user has not finished exercising (step S208; No), the process returns to step S202. If the user has finished exercising (step S208; Yes), the indicator display process ends.

[0036] Through the indicator display process described above, the electronic device 100 displays the indicators to be improved that have the highest priority (improvement-recommended indicators) in an easy-to-see area, allowing the user to quickly grasp the necessary information from a wide range of information. Furthermore, by displaying the target values ​​of the improvement-recommended indicators, the user can obtain a direction for how to improve their exercise. Furthermore, since the improvement-recommended indicators are selected in descending order of their contribution to increasing the score, the user can work on improving the indicators that are most likely to increase the score. Furthermore, since the current index values ​​(present values) of the improvement-recommended indicators are displayed in real time while the user is exercising, points for improving the user's level that could previously only be viewed after the exercise can be viewed during the exercise (e.g., while running), making it easier for the user to recognize whether their form is improving. Furthermore, since the display mode of improved indicators changes while the user is exercising, the user can grasp the improvement of the indicators in real time, which increases the user's motivation to improve their exercise form.

[0037] In the above-described index display process, the control unit 110 changes the display mode of the index value when the index value of the index recommended for improvement is improved. However, instead of (or in addition to) changing the display mode, the audio output unit 160 may output a sound effect or a voice message notifying that the index value has improved. Furthermore, even when the value of the index recommended for improvement is deteriorated, instead of (or in addition to) changing the display mode, the audio output unit 160 may output a sound effect or a voice message notifying that the index value has deteriorated. When outputting by sound, it is difficult to notify changes in the index value in real time, so it is also possible to notify whether the index value of the index recommended for improvement has improved or deteriorated based on an average value over a predetermined period of time (for example, 10 minutes).

[0038] Furthermore, in the above-described embodiment, electronic device 100 includes measurement unit 130, and electronic device 100 alone is able to acquire measurement values, which are data related to the user's exercise, from measurement unit 130. However, a configuration in which measurement unit 130 exists as a device separate from electronic device 100 is also possible. For example, an electronic device system including a sensor device including measurement unit 130 and a communication unit, and an electronic device configured by removing measurement unit 130 from electronic device 100 and adding a communication unit (sensor-less electronic device) may be configured to perform the same processing as electronic device 100 described above.

[0039] In such an electronic device system, the control unit 110 of the sensorless electronic device acquires the measurement values ​​measured by the measurement unit 130 of the sensor device via the communication unit, and the control unit 110 can execute index extraction processing, index display processing, etc. When using this electronic device system, the user can, for example, wear the sensor device on their waist and the sensorless electronic device on their arm, thereby achieving both highly accurate measurement value acquisition and easy-to-read display of indexes, etc.

[0040] Furthermore, the earphones serving as the audio output unit 160 may be configured as separate ear devices that communicate with the electronic device via short-range wireless communication such as Bluetooth (registered trademark). Furthermore, the display unit 140 may be configured as a separate display device that communicates with the electronic device via short-range wireless communication. In this way, the electronic device 100 does not need to have all of its components in a single housing, and any functional unit (such as the measurement unit 130, display unit 140, operation input unit 150, and audio output unit 160) may be configured as separate units as needed.

[0041] In addition, in the above embodiment, the user's exercise is mainly described as running, but the user's exercise handled by electronic device 100 is not limited to running. For example, it may be walking or cycling. The derived and displayed indexes and evaluation items may be changed as desired depending on the type of exercise, etc.

[0042] Furthermore, electronic device 100 is not limited to a wearable device, and can also be realized by a computer such as a smartphone, portable tablet, or PC (Personal Computer) that can acquire measurement values ​​from measurement unit 130. Specifically, in the above embodiment, the programs for the index extraction process, index display process, and the like executed by control unit 110 have been described as being pre-stored in storage unit 120. However, the programs may be stored and distributed on a non-transitory computer-readable recording medium such as a flexible disk, CD-ROM (Compact Disc Read Only Memory), DVD (Digital Versatile Disc), MO (Magneto-Optical disc), memory card, or USB memory, and the programs may be read and installed on a computer to configure a computer that can execute each of the above-mentioned processes.

[0043] Furthermore, the program may be superimposed on a carrier wave and applied via a communication medium such as the Internet. For example, the program may be posted and distributed on a bulletin board system (BBS) on a communication network. The program may then be started and executed under the control of an operating system (OS) in the same way as other application programs, thereby enabling the above-described processes to be performed. In addition, the control unit 110 may be configured by any single processor such as a single processor, multiprocessor, or multi-core processor, or by combining any of these processors with processing circuits such as an ASIC (Application Specific Integrated Circuit) or FPGA (Field-Programmable Gate Array).

[0044] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to such specific embodiments, and the present invention includes the inventions described in the claims and their equivalents. [Explanation of symbols]
