In FIG. 1, a configuration necessary for detailed description is shown, but even a configuration essential for the mobile device 10 is omitted for those not described in the present specification.

  As shown in FIG. 1, an X-axis sensor 12, a Y-axis sensor 13, and a Z-axis sensor 14 are mounted on the magnetic sensor 11. The magnetic sensor 11 is attached to the portable device 10 with reference X direction, reference Y direction, and reference Z direction orthogonal to each other.

  The signal processor 16 includes an A / D converter, an amplifier circuit, a control circuit, and the like. In response to a measurement command from the control circuit based on the program recorded in the first storage unit 17, the signal processing unit 16 performs the X-axis sensor 12, the Y-axis sensor 13, and the Z-axis sensor 14 of the magnetic sensor 11. Each sensor output is intermittently read into the amplifier circuit in a short cycle, converted into a digital value by the A / D converter in the signal processor 16 and transmitted, and so forth.

  Unlike the game using GPS (Global Positioning System), the first embodiment has the following effects. It can be enjoyed indoors where GPS does not function, and since movement such as walking is not essential, training can be performed basically anywhere, regardless of the place where training is performed. Furthermore, since it is not necessary to spend traveling time, a sensible application that can be enjoyed in a short time becomes possible, and can be carried out at night or during breaks. Therefore, it is possible to provide a portable device that can be enjoyed like a game even for a short time and can be applied to health management.

  In the first embodiment, a magnetic sensor 11 that detects geomagnetism includes a GMR (Giant Magneto-Resitive) element, an AMR (Anisotropic Magneto-Resitive) element, a TMR (Tunnel Magneto-Resitive) element, and a GIG (Gran (Gulan) Gan (Granul Ingan) element. A magnetoresistive effect element such as a Hall element, an MI (Magneto-Impedance) element, and other magnetic detection elements can be used. Each of the X-axis sensor 12, the Y-axis sensor 13, and the Z-axis sensor 14 may be a single-axis sensor element, a plurality of elements including an integrated two-axis sensor element, or an integrated three-axis sensor. It may be a sensor element. Note that the magnetic sensor 11 may be a sensor having three or more axes, or may be a two-axis sensor. However, as a sensor configuration in which the portable device 10 can be used in any orientation, the three-axis sensors such as the X-axis sensor 12, the Y-axis sensor 13, and the Z-axis sensor 14 are suitable for downsizing.

  The first storage unit 17 may be a memory incorporated in the control circuit of the signal processing unit 16. Further, the first storage unit 17 may be divided into a built-in memory of the control circuit and an external memory. As shown in FIG. 1 and FIG. 2, the geomagnetic sensor module 25 in which the magnetic sensor 11, the signal processing unit 16, and the first storage unit 17 are integrally stored is preferable. The geomagnetic sensor module 25 may be either a package product or a board mounted product. In particular, the package product is suitable for downsizing. Alternatively, the signal processing unit 16 may also serve as the azimuth calculation unit 18. In this case, the geomagnetic sensor module 25 in which the magnetic sensor 11, the signal processing unit 16, the first storage unit 17, and the azimuth calculation unit 18 are integrally stored may be used.

  Although the azimuth calculation unit 18 calculates the azimuth, the geomagnetism may be bent by an object near the use position or a structure in the building, and in such a case, the correct azimuth cannot be calculated. is there. However, in the first embodiment, the orientation of the body at the time of training is converted into data, and if the training method is such that the use position hardly changes, the progress of the training is not affected even if there is a geomagnetic curve. .

  Further, if the magnetic sensor 11 for detecting geomagnetism is provided, it can be applied to a music player, a digital still camera, a multi-remote controller, etc. in addition to a mobile phone or a portable game machine. Of course, the magnetic sensor 11 itself for detecting geomagnetism can be applied to applications other than the training described in the first embodiment, and can also be used for various applications.

  As described in detail in the first embodiment, it is preferable that the training program is executed by the operator holding the portable device 10 in both hands. It is effective for the health management of the operator by setting the training content on the assumption that the mobile device 10 is moved by the whole body.

  Furthermore, it is good also as a training program performed by an operator sitting in a rotatable chair. In this way, not only does it take a special place other than a chair, but it can also be enjoyed safely and with moderate exercise intensity by elderly people with weak legs and those who are rehabilitating due to injury or illness. It is.

  Further, for example, it may be a training content in which the portable device 10 is placed on a knee while sitting on a chair and the chair is rotated. In this way, it is possible to provide a bodily sensation application that can be enjoyed even by people who are difficult to hold with both hands.

  In this way, by using the mobile device 10 as a training content for moving the body, it is possible to perform exercises with fitness effects, rehabilitation applications that compete for quick reaction, and brain activation games. . Furthermore, it is possible to accumulate data and graph the degree of proficiency, or to display advice according to the operator's habit, personality, or physical ability.

  Furthermore, instead of physical training, it may be a game that competes for the speed of reaction or brain activation training. For example, instead of moving the mobile device 10 with the body, the orientation may be changed by hand so that only the mobile device 10 is rotated. In this way, even a person whose movement is restricted due to injury or illness on a bed, for example, can enjoy it, and an appropriate training effect can be obtained.

  The content of the bodily sensation application may be a game. For example, it is possible to make a game where points are added when the azimuth is matched within a predetermined time, such as tapping a mole.

  As described above, using the portable device 10 capable of executing the training program using the output of the magnetic sensor 11 that detects geomagnetism, a sensation application that can be enjoyed even in a room where GPS does not function, and a sensation that promotes light exercise that can be performed in a short time. The application can be executed. Thereby, various trainings can be provided by a mobile phone incorporating a magnetic sensor for detecting geomagnetism or a game machine (main body or memory card) incorporating a magnetic sensor for detecting geomagnetism.

<Second Embodiment>
FIG. 9 is a block diagram showing a schematic configuration of the portable device 10 in the second embodiment of the present invention, and FIG. 10 is a flowchart showing a training control method executed in the second embodiment. The geomagnetic sensor module 25 is the same as that in the first embodiment.

  As shown in FIG. 9, in the second embodiment, the processing unit 20 includes an azimuth calculation unit 18 and an angular velocity calculation unit 19. The processing unit 20 performs arithmetic processing in which the azimuth calculating unit 18 calculates an azimuth using the digital value transmitted from the signal processing unit 16 based on programmed software stored in advance in the second storage unit 21. The angular velocity calculation unit 19 performs calculation processing for calculating the angular velocity.

  In addition to this, also in the second embodiment, the processing unit 20 reads a training program stored in advance in the second storage unit 21 and sets the training content according to the progress of the training. The processing unit 20 receives the above-described arithmetic processing data, performs a determination process based on the training content, and performs a process of displaying the progress of the training and the determination result on the display unit 22.

  Next, a training control method executed in the second embodiment will be described using the flowchart shown in FIG.

  When the operator performs a predetermined operation on the mobile device 10, the training program is read and started. In step S11, the initial azimuth is calculated from the output of the magnetic sensor 11 for detecting geomagnetism. In step S12, the set orientation is read, and the set training content is displayed on the display unit 22. Subsequently, in step S13, the current azimuth is calculated from the output of the magnetic sensor 11 that detects geomagnetism. Similarly, in step S14, the angular velocity is calculated from the output of the magnetic sensor 11. At this time, the first determination process is performed in step S15, and the set direction in step S12 and the current direction in step S13 are compared to determine whether or not the matching condition is satisfied. When there is no matching condition in the first determination process, the process is repeated from step S13. If there is a match in the first determination process, the second determination process is performed in step S16, the time until the match is calculated, and the maximum angular velocity is calculated from the angular velocity data obtained in step S14. Is done. In the subsequent step of S17, the next training progress condition and the processing results of the first determination process and the second determination process are displayed on the display unit 22, and the progress of the training by the new set orientation is repeated.

  The current azimuth and the angular velocity applied to the mobile device 10 are calculated from the output of the magnetic sensor 11, the coincidence between the set azimuth and the current azimuth is determined, and the time until the coincidence and the maximum angular velocity of the movement of the body are determined. Be evaluated.

  The angular velocity calculation unit 19 preferably outputs the angular velocity data when the angular velocity is equal to or greater than a threshold value. The threshold is set to a predetermined value that is not affected by noise or the like.

  The azimuth calculation unit 18 and the angular velocity calculation unit 19 may also serve as the signal processing unit 16. In this case, the geomagnetic sensor module 25 in which the magnetic sensor 11, the signal processing unit 16, the first storage unit 17, the azimuth calculation unit 18, and the angular velocity calculation unit 19 are integrally housed may be used.

  Also in the second embodiment, the training and experience application described in the first embodiment can be applied as they are.

  Furthermore, in the second embodiment, since the angular velocity calculation unit 19 is provided, the physical ability corresponding to the instantaneous force can be evaluated using the data. Thereby, it is possible to score the instantaneous power in association with the age of the operator. In this way, the accuracy of determination or evaluation can be increased. Further, since only the magnetic sensor 11 for detecting geomagnetism is used and the angular velocity can be calculated without using other sensors, applications other than training are possible, and the present invention can also be applied to applications using various angular velocity data.

  Next, an embodiment in which the training control method of the present invention is experimentally confirmed with a training program for confirming the principle will be described.

  FIG. 11 is a graph showing the set azimuth and the calculated current azimuth in this embodiment. The relationship between the elapsed time from the training program start (step of S11) of the portable device 10 detailed in the embodiment of the present invention and the current direction calculated from the output of the magnetic sensor 11 (step of S13) is shown. The training content set in step S12 is to match the current orientation of the body (portable device 10) with the setting orientation indicated by the solid line. The current direction calculated from the output of the magnetic sensor 11 is plotted every 0.1 seconds. The operator changes the current azimuth to match the set azimuth, but a delay time occurs in the movement of the operator, and a difference between the set azimuth and the current azimuth occurs.

  FIG. 12 is a graph showing the calculated angular velocity of this embodiment. In FIG. 12, the angular velocity (step of S14) calculated from the output of the magnetic sensor 11 is shown. Here, the data is sampled so as to reduce the influence of noise and used as data indicating the quickness of the operator's reaction.

  In the first determination process (step S15) in the present embodiment, the determination content is that the current direction matches the set direction sampled at a predetermined time interval with a delay time. As shown in FIG. 11, the operation is a setting azimuth that swings the azimuth by 90 degrees to the left and right, and the determination processing is performed so as to determine the coincidence between the setting azimuth and the current azimuth in consideration of the delay time. At this time, if the current azimuth is within a range of plus or minus 5 degrees, it is determined that they match. In the second determination process (step S16), the difference between the current angle and the set angle sampled at intervals of 0.1 second and the delay time and the calculation process of the maximum angular velocity were performed. In this example, 300 degrees / second was calculated as the maximum angular velocity at the time of 2.4 seconds.

  Table 1 shows a part of the processing data of the difference between the current angle and the set angle (angle shift) and the delay time in the second determination process (step S16). From the sampled measurement data, Σ (angle shift) which is the sum of the set angle differences (angle shift) and Σ (delay time) which is the sum of the delay times were calculated. Subsequently, from these calculated values, the score = Σ (shift in angle) × Σ (delay time) was obtained. In the example of Table 1, the score was 32,665, but in this case, the scoring method is better when the score is smaller.

  Based on this score of 32,665 and the maximum angular velocity of 300 degrees / second, according to a predetermined evaluation criterion, determination such as “determination result (OK / NG)” or evaluation such as “evaluation age XX” is performed. The result of processing is displayed on the display unit 22. It should be noted that options such as whether to execute again or end together with the processing result are displayed, and the same training may be repeated, switched to another training, or the training may be ended.

  Note that these training contents and determination process contents are provided as appropriate, and are not limited to the contents of the above-described embodiments and examples.
