Description

  The present invention relates to a motion command processing system.

  A gyro is a sensor that measures the speed of rotation (rotational angular velocity) with respect to a rotational motion around a certain rotational axis. The “vibration gyro sensor” that is widely used today detects the angular velocity using the “Coriolis force”.

  For example, in a vibrating gyroscope that operates using the piezoelectric effect, when an AC voltage is applied to a gyro element (vibrating body such as a crystal), a Coriolis force is generated, and a current is generated according to the rotation rate and angular velocity. The current signal is amplified inside the gyro sensor, and a voltage proportional to the angular velocity is output.

Recently, an ultra-small and low power consumption gyro sensor has been developed, packaged together with an analog front-end circuit and an A / D conversion circuit, mounted on a mobile phone, a digital camera, etc., and used for camera shake correction and the like.

  In this embodiment, the command is executed not only by performing an operation input from an operation unit such as a key or a button provided in the mobile device, but also by performing an operation of shaking the mobile device itself (motion). be able to. Here, the user can register the motion of the mobile device and the command to be executed in advance.

  That is, a predetermined operation (for example, an operation such as selecting a motion command registration mode on the screen and performing a definite input) is performed on the mobile device, thereby setting the motion command registration mode. Then, the gripper shown in FIG. 9 is gripped to perform a motion. For example, a command corresponding to the input motion is specified from the screen of the mobile device, and the specified command and the rotational angular velocity value generated by the motion or information regarding the rotational angular velocity value and the acceleration value are stored in the motion specifying information storage unit. . Then, the motion command registration mode is terminated.

  In this way, for example, different motions shown in 510, 520, and 530 in FIG. 11 can be registered in association with different commands. Here, the 510 command corresponds to the A command “call to the registered partner” and the 520 motion corresponds to the B command “lock the operation of the mobile device” to the 530 motion. May correspond to the C command “release the operation lock of the portable device”.

  In this way, it is possible to make a call to the registered partner by making the mobile device move like 510, and to lock the operation of the mobile device by making the mobile device move like 520. The operation lock of the mobile device can be released by making the mobile device move like 530.

  FIG. 12 is a flowchart for explaining the flow of processing for detecting a motion command using the rotational angular velocity.

  First, the rotational angular velocity is detected by the gyro sensor (step S10).

  Next, the analog voltage value output from the gyro sensor is converted into a digital voltage value (step S20).

  Next, the rotational angular velocity value (digital voltage value) is input and held in the work buffer (step S30).

  Next, the rotational angular velocity values for the past x seconds are compared with the rotational angular velocity data of a given motion stored in the motion identification information storage unit (step S40).

  If the error is within a predetermined range (step S50), the command associated with the given motion is executed (step S60).

  FIG. 13 is a flowchart for explaining the flow of processing for detecting a motion command using the rotational angular velocity and acceleration.

  First, the angular velocity is detected by the gyro sensor and the acceleration is detected by the acceleration sensor (step S110).

  Next, the analog voltage value output from the gyro sensor and the analog voltage value output from the acceleration sensor are converted into digital voltage values (step S120).

  Next, the digital voltage values of the rotational angular velocity and acceleration are input and held in the work buffer (step S130).

  Next, the rotation angular velocity value and acceleration data held for the past x seconds are compared with the rotation angular velocity and acceleration data of a given motion stored in the motion identification information storage unit (step S140).

  If the error is within a predetermined range (step S150), the command associated with the given motion is executed (step S160).

  FIG. 14 is a flowchart for explaining the flow of the motion command registration process.

  If it is in the motion registration mode, the following processing is performed (step S210).

  If contact is detected in the gripping part (step S220), the rotational angular velocity value (digital voltage value) is input and held in the work buffer (step S230), and given based on the rotational angular velocity value received within the motion registration period. Motion identification information for detecting the occurrence of motion is generated and registered in the motion identification information storage unit (step S240).

  FIG. 15 is a flowchart for explaining a learning function for detecting a motion command.

  First, the rotational angular velocity is detected by the gyro sensor (step S410).

  Next, the analog voltage value output from the gyro sensor is converted into a digital voltage value (step S420).

  Next, the rotational angular velocity value (digital voltage value) is input and held in the work buffer (step S430).

  Next, an allowable range (a predetermined range including an average value, a predetermined range including a maximum value, a predetermined range including a minimum value, etc.) is determined based on the motion history information of a given motion stored in the motion identification information storage unit, and the past x seconds. It is determined whether or not the rotational angular velocity value is within an allowable range (step S440). For example, it is assumed that z pieces of input values that have been determined to be a given motion command in the past are stored as motion history information in the motion identification information storage unit.

  If the error is within a predetermined range (step S450), a command associated with the given motion is executed (step S460), and motion identification information is generated based on the acquired rotational angular velocity values for the past x seconds. The motion identification information is stored in the motion identification information storage unit, and the oldest motion history information related to the motion is deleted from the motion identification information storage unit (step S470). This updates the motion history information to the latest state.

  In this embodiment, by determining the allowable range using the motion history information, there is a learning effect that the latest user input tendency can be reflected in the motion determination.

  FIG. 16 is a flowchart for explaining processing for detecting a fall and executing a predetermined command.

  First, obtain a plurality of samples of rotational angular velocity values at the time of falling, determine rotational angular velocity values for detecting the occurrence of falling based on the plurality of samples or information on transitions of the rotational angular velocity values and acceleration values, and as motion specifying information The motion specifying information storage unit is made to operate (step S510). This process is performed before product shipment.

  Next, the rotational angular velocity is detected by the gyro sensor, and the acceleration is detected by the acceleration sensor (step S520).

  Next, the analog voltage value output from the gyro sensor and the analog voltage value output from the acceleration sensor are converted into digital voltage values (step S530).

  Next, the digital voltage values of the rotational angular velocity and acceleration are input and held in the work buffer (step S540).

  It is detected whether or not a drop has occurred based on the retention data of the rotational angular velocity values and acceleration values for the past x seconds and the motion specifying information for detecting the occurrence of the drop (step S550).

  When the occurrence of a drop is detected (step S560), a command associated with the drop is executed (step S570).

  Next, a command for transmitting fall notification information for notifying the occurrence of a fall event to a predetermined address registered in advance is executed (step S580).

  FIG. 17 is a diagram for describing a specific application example of the present embodiment.

  In the mobile device in which the motion command processing system of this embodiment is incorporated, motion specific information for detecting a motion that occurs when “dropping” or a motion that occurs when “dropped” is stored in the motion specific information storage unit in advance. Has been. When a motion that occurs when “drop” or a motion that occurs when “drop” is detected, the lock command is set to be executed.

  In addition, it is assumed that the mobile device in which the motion command processing system of the present embodiment is incorporated is configured to be able to register a motion command, and the user registers a motion for unlocking.

  When the mobile device falls (S610), the lock command is executed corresponding to the motion that occurs when the rotational angular velocity or the rotational angular velocity and acceleration values detected at that time are “dropped”, thereby causing the mobile device to The lock is applied and the operation becomes invalid (S630).

  Also, when the portable device is snatched (S620), the lock command is executed corresponding to the motion that occurs when the detected rotation angular velocity or the value of the rotation angular velocity and acceleration is “snacked”. The portable device is locked and the operation becomes invalid (S630).

  In this case, the third party cannot operate because the portable device is locked. Therefore, it is possible to prevent the portable device from being abused by a third party.

  The user can release the lock by performing the unlock motion registered by the user (S640).

  As described above, since the unlocking method is limited to only the user who has registered the unlocking motion, the third party cannot unlock it. Therefore, a portable device having a high security function can be provided.

  FIG. 18 is a diagram for describing another specific application example of the present embodiment.

  The mobile device in which the motion command processing system of the present embodiment is incorporated has a motion identification for detecting a motion that occurs when “keep”, a motion that occurs when “not operated”, and a motion that occurs when “lift” occurs. Information is stored in advance in the motion identification information storage unit. And if a motion that occurs in the case of “putting” or a motion that occurs in the case of “no operation” is detected, the lock command is set to be executed, and the motion that occurs in the case of “lifting” is detected In some cases, a wake-up command is set to be executed.

  In addition, it is assumed that the mobile device in which the motion command processing system of the present embodiment is incorporated is configured to be able to register a motion command, and the user registers a motion for unlocking.

  When the portable device is placed (S710), the lock command is executed corresponding to the motion that occurs when the rotation angular velocity or the value of the rotation angular velocity and acceleration detected at that time is “put”, and thereby the portable device is executed. Is locked and the operation becomes invalid (S730).

  When the portable device is not operated (S720), the lock command is executed corresponding to the motion that occurs when the detected rotational angular velocity or the rotational angular velocity and acceleration are “unoperated”. As a result, the portable device is locked and the operation becomes invalid (S730).

  Then, after a predetermined period has elapsed after the lock (the predetermined period is counted by a timer or the like), the mode is shifted to a sleep mode in which only the lowest function is operated (S740). By doing so, it is possible to automatically save power when locked.

  When the portable device is lifted (S750), the wake-up command is executed corresponding to the motion that occurs when the rotational angular velocity or the rotational angular velocity and acceleration values detected at that time are “lifting”, whereby the portable device is executed. Shifts from the sleep mode to the normal mode (S750).

  The user can release the lock by performing the unlock motion registered by the user (S760).

  In addition, this invention is not limited to this embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention.

  For example, in the above-described embodiment, the case where the motion command is detected using the rotational angular velocity about one axis has been described as an example, but the present invention is not limited thereto. For example, the configuration may be such that a motion command is detected by detecting rotational angular velocities about three axes.
