Description

  The present invention relates to an operation mode setting apparatus, method, program, and computer-readable medium storing the program for setting an operation mode of a mobile phone, and more particularly, based on a moving scene of a user. The present invention relates to an operation mode setting apparatus, method, program, and computer-readable medium storing the program.

  The spread of mobile phones in recent years has brought various conveniences to society. However, on the other hand, there are many cases where the manner of using a mobile phone becomes a problem, for example, a ring tone sounds in a public place such as a train, or a loud call is made. There are also concerns about adverse effects on medical devices such as pacemakers.

  Further, when a mobile phone is used while walking, attention to the surroundings is distracted, which can be dangerous for the user himself or others. In addition, the use of mobile phones while driving cars and motorcycles is prohibited by the Road Traffic Law, but in reality, they are not fully observed.

  In view of such circumstances, mobile phone providers provide various operation mode functions in mobile phones. The main operation modes include a manner mode in which a ring tone is muted and a call is restricted, and a drive mode in which normal operation is restricted.

  These operation mode functions are set manually by the user, and the optimum mode is not automatically selected according to the situation. Therefore, when the user does not intend to use the operation mode or forgets to set the operation mode, these functions do not contribute to the improvement of manners and safety.

  In order to solve the above inconvenience, Patent Document 1 discloses a technique for controlling the operation of a mobile communication terminal. Specifically, the acceleration sensor attached to the mobile communication terminal is used to determine whether or not the user of the terminal is on a commuter train. The operation mode of the mobile communication terminal is automatically set to the manner mode. Thereby, when the user of the mobile communication terminal gets on the commuter train, the operation mode of the mobile communication terminal is surely set to the manner mode.

  In the method described in the above document, it is necessary to register in advance a time zone (that is, a commuting time zone) with a high possibility of getting on a commuter train. Then, it is determined whether or not the user is on the train only during this time period. This is because, as described in paragraph 0031 of this document, it is difficult to accurately determine whether or not the user is on the train only with the vibration pattern obtained from the acceleration data. Therefore, only the limited time zone, that is, the commuting time zone is determined, and the operation mode is not automatically set outside the commuting time zone.

  In addition, it is determined whether or not the user is on a commuter train. In other scenes, for example, whether or not the user is walking or whether or not the user is driving a car. This is not supported.

It is a flowchart of the operation mode setting method which the operation mode setting apparatus concerning one Embodiment of this invention performs.

A configuration of an operation mode setting device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[Operation mode setting device 10]
FIG. 1 shows a functional block diagram of an operation mode setting device 10 according to an embodiment of the present invention. The operation mode setting device 10 is a device built in an existing mobile phone 1000 having a plurality of operation mode functions such as a manner mode and a drive mode, and realized by the function of the mobile phone.
The operation mode setting device 10 is roughly composed of a vibration processing block 20, a noise processing block 30, an image processing block 40, and an operation mode determining unit 400.

  The vibration processing block 20 has a function of detecting vibration applied to the mobile phone 1000, specifying a detected vibration pattern, and extracting a scene corresponding to the specified pattern. The vibration meter 100 and a vibration pattern specifying unit 110, a first scene extraction unit 120, and a first scene table unit 130. The vibrometer 100 is a functional element that detects vibration in the three-dimensional direction of the mobile phone 1000, and is mounted by a general acceleration sensor using a piezoelectric element or the like. As the vibration meter 100, an acceleration sensor for a pedometer built in the mobile phone 1000 may be used. The vibration pattern specifying unit 110 analyzes the vibration data detected by the vibrometer 100 and specifies the vibration pattern. Specifically, a continuous electrical signal output from the vibrometer 100 is sampled at a predetermined time interval and converted into a digital format signal, and then changes in frequency and amplitude within a certain time are measured, The characteristic (pattern) and period of the vibration are obtained. The above process is performed several times to several tens of times, and a filtering process is performed as necessary to generate a vibration pattern. When the vibration pattern is generated, the vibration pattern specifying unit 110 accesses the first scene table unit 130.

  The first scene table unit 130 has a database function, and is used in a scene that is acquired by a user of the mobile phone 1000 in advance or on a train, a car, a bus, a motorcycle, a bicycle, or the like. A vibration pattern is registered in advance as a template vibration pattern. The vibration pattern specifying unit 110 performs pattern matching using the generated vibration pattern and the vibration pattern registered in the first scene table unit 130 based on the change in frequency and amplitude and the period.

  The first scene extraction unit 120 selects a template vibration pattern that is most similar to the generated vibration pattern as a result of pattern matching performed by the vibration pattern specifying unit 110, extracts a scene corresponding to the selected pattern, and The result is sent to the operation mode determination unit 400.

  The noise processing block 30 has a function of detecting noise around the mobile phone 1000, specifying a detected noise pattern, and extracting a scene corresponding to the specified pattern. The microphone 200, the noise pattern specifying unit 210, The second scene extraction unit 220 and the second scene table unit 230 are configured. The microphone 200 is a functional element that detects noise around the mobile phone 1000, and a transmitter installed in the mobile phone 1000 may be used. The noise pattern specifying unit 210 analyzes the noise data detected by the microphone 200 and specifies the noise pattern. Specifically, the volume of noise and the cycle of noise are measured from the continuous electrical signal output from the microphone 200. Further, a continuous electric signal is sampled at a predetermined time interval and converted into a digital signal, and then FFT (Fast Fourier Transform) processing is performed. This process is performed several times to several tens of times to calculate the average frequency spectrum of noise. Filtering processing is performed as necessary to generate a noise pattern using noise volume, period, and frequency spectrum as elements. Furthermore, a predetermined weighting process may be performed on the voice power in the low frequency region in order to reduce the influence of the human voice. When the noise pattern is generated, the noise pattern specifying unit 210 accesses the second scene table unit 230.

  The second scene table unit 230 has a database function, and is used in a scene when walking on a mobile phone 1000 acquired in advance by a user or traveling on a train, automobile, bus, motorcycle, bicycle, or the like. Noise patterns are registered in advance as template noise patterns. The noise pattern specifying unit 210 performs pattern matching using the generated vibration pattern and the vibration pattern registered in the second scene table unit 230 as elements of noise volume, period, and frequency spectrum.

  The second scene extracting unit 220 selects a template noise pattern that is most similar to the generated noise pattern as a result of pattern matching performed by the noise pattern specifying unit 210, extracts a scene corresponding to the selected pattern, and The result is sent to the operation mode determination unit 400.

  The operation mode determination unit 400 is a functional element that determines an operation mode to be set based on the scenes extracted by the first scene extraction unit 120 and the second scene extraction unit 220. Usually, vibration and noise change in time series and reproducibility is not so high. Therefore, the scene extracted from vibration and noise is processed a plurality of times to finally determine the user's scene. An example of a method for finally determining a user's scene is shown below.

  Table 1 is an example of a scene determination result by the vibration processing block 20 and the noise processing block 30. In this example, the final determination is made using the processing result of 5 times, but the number of times is not limited to 5 and may be any number. It goes without saying that the greater the number of times, the longer the processing time but the better the decision accuracy.

  The processing result may be weighted. That is, weighting processing may be performed on either or both of the scene determination results of the vibration processing block 20 and the noise processing block 30. The inventors have confirmed through experiments that vibration can extract a user's scene more accurately than noise. Therefore, the scene determination result of the vibration processing block 20 is weighted by “2”, the scene determination result of the noise processing block 30 is “1” without weighting, and the score is totaled for each scene.

  As a result of the calculation, the train is “8”, the bus is “3”, the car is “2”, the motorcycle is “1”, and the bicycle is “1”. " Subsequently, the operation mode determination unit 400 selects an operation mode corresponding to the scene of the final determination result (in this case, the manner mode is selected), and sets the selected operation mode in the operation mode switching unit of the mobile phone 1000. Send the command.

  However, when the finally determined scene is “in a car”, the operation mode determination unit 400 does not send a command to the operation mode switching unit of the mobile phone 1000, and the image processing block 40 will be described below. To do.

  The image processing block 40 captures the landscape in front of the user, identifies the pattern of the captured image, and based on the identified image pattern, is the user in the driver's seat of the car or in a seat other than the driver's seat? And includes a camera 300, an image pattern specifying unit 310, a third scene extracting unit 320, and a third scene table unit 330.

  The camera 300 has a function of capturing a landscape and outputting the captured image as digital image data in a predetermined format. The camera 300 may be a digital camera attached to the mobile phone 1000. The image pattern specifying unit 310 analyzes digital image data output by the camera 300 using an existing image processing technique such as pattern matching.

  The third scene table unit 330 includes an image taken by the user as seen from the driver's seat of the automobile (see FIG. 2A), an image seen from the passenger seat (see FIG. 2B), and a rear seat. Template images (see FIGS. 2C to 2E) are registered in advance. The image pattern specifying unit 310 identifies a handle in the processed image output from the camera 300, and then identifies each handle of the template image registered in the third scene table unit 330. For the identification of the handle, the template closest to the size of the handle of the processed image is applied by applying an existing image processing technique related to template matching such as image capture, graying, binarization of the gray image, and comparison of two images. Select an image.

  The third scene extraction unit 320 determines whether the user is in the driver's seat based on the result of template matching performed by the image pattern identification unit 310 and sends the result to the operation mode determination unit 400.

  The operation mode determination unit 400 determines an operation mode corresponding to the result received from the third scene table unit 330, and sends a predetermined command to the mode switching unit of the mobile phone 1000 so that the determined operation mode is obtained.

  In the above procedure, the relationship between the scene of the user of the mobile phone 1000 and the operation mode determined by the operation mode determination unit 400 is shown below.

  Further, restrictions on the functions of the operation modes in Table 2 are shown below.

  As described above, the operation mode setting device 10 according to an embodiment of the present invention is based on the vibration and noise around the mobile phone 1000, and the user of the mobile phone is walking, or train, bus The driver's seat based on the image of the front of the user when it is determined that the user is on a car, motorcycle, bicycle, etc. A function of determining whether or not the vehicle is driving because the vehicle is moving, and extracting and setting an operation mode suitable for the scene.

[Operation mode setting method]
Next, an operation mode setting method of the mobile phone 1000 that is actually performed by the operation mode setting device 10 having the above functions will be described with reference to the flowchart of FIG.

  First, as a pre-procedure for executing this method, vibration and noise in a scene to be specified in advance are registered (step S1). Examples of the scene to be specified include a scene where the user is walking and a scene where the user is riding on any of a train, a bus, an automobile, a motorcycle, and a bicycle. In addition, when a scene in a car is registered, a front image viewed from the driver seat, the passenger seat, and the rear seat is also registered. By this registration operation, vibration data is stored as template data in the first scene table unit 140, noise data is stored in the second scene table unit 240, and image data is stored as template data in the third scene table unit 340. .

When the pre-procedure of Step S1 is completed, the main procedure is performed below.
In the procedure of step S2, vibrometer 100 detects the vibration of mobile phone 1000. This detection may be repeatedly performed in a predetermined period. Increasing the number of repetitions improves the scene identification accuracy, but increases the power consumption of the mobile phone 1000 and shortens the battery life. Please select the optimal number of iterations in consideration of these trade-offs.

  In the procedure of step S3, based on the vibration data detected by the vibrometer 100, the vibration pattern specifying unit 110 specifies the vibration pattern of the vibration data.

  In the procedure of step S4, the first scene extraction unit 130 extracts a scene corresponding to the vibration pattern specified by the vibration pattern specification unit 110. The extracted scene is sent to the operation mode determination unit 400.

  In the procedure of step S5, the microphone 200 detects noise around the mobile phone 1000. This detection may be repeated for a predetermined period as in the procedure of step S2.

  In the procedure of step S6, the noise pattern specifying unit 210 specifies a noise pattern based on the noise data detected by the microphone 200.

  In the procedure of step S7, the second scene extraction unit 220 extracts a scene corresponding to the noise pattern specified by the noise pattern specification unit 210. The extracted scene is sent to the operation mode determination unit 400.

  Note that the procedure from step S2 to step S4 and the procedure from step S5 to step S7 may be performed simultaneously.

  In the procedure of step S8, the operation mode determination unit 400 finally determines the user's scene based on the scenes received from the first and second scene extraction units 120 and 220. Further, in the procedure of step S9, it is determined whether or not the determined scene is “in a car”.

  When the determination result in step S9 is not “in a car” (“No” in step S9), the process proceeds to step S13, and the operation mode determination unit 400 determines an operation mode corresponding to the determined scene. To do. Next, a predetermined command is sent to set the operation mode determined by the operation mode determination unit 400 to the operation mode switching unit of the mobile phone 1000 in the procedure of step S14.

  On the other hand, when the determined scene is “in the car” (“Yes” in step S9), the process proceeds to step S10, and the camera 300 captures an image of the front of the user. When a user sits in the driver's seat of a car and holds a mobile phone in hand, the digital camera attached to the mobile phone will face the front of the user and take the image as it is. Will occupy most of the screen. Therefore, this imaging function may be operated by detecting that the user has started to operate the mobile phone with a keypad input detection unit (not shown) of the mobile phone.

  In the procedure of step S11, the image pattern specifying unit 310 specifies the image pattern of the image data captured by the camera 300, specifically, the handle unit, and further accesses the third scene table unit 330 to obtain the template image. A matching process is performed with the handle part.

  In the procedure of step S12, the third scene extraction unit 320 determines whether the user is sitting in the driver's seat based on the matched image pattern. The determination result is sent to the operation mode determination unit 400.

In the procedure of step S13, the operation mode determination unit 400 determines the operation mode corresponding to the determined scene, and in the procedure of step S14, the operation mode switching of the mobile phone 1000 is set so as to set the operation mode corresponding to the determined scene. A predetermined command is sent to the section.
The above is the operation mode setting method executed by the operation mode setting device 10 according to the embodiment of the present invention.

The function of the operation mode setting device 10 of the present invention is not limited to the contents of the above embodiment. For example, the procedure of step S1 in FIG. 3 may be omitted, and each pattern data may be registered by default instead. If the detected vibration and noise pattern does not correspond to any scene in the procedure of step S8, the procedure after step S9 may be interrupted to cancel the current operation mode.
As a result, when the user gets off the train, bus, car, motorcycle, bicycle, etc., stops walking, stops the car and stops driving, the operation mode is changed to the normal mode. Can be returned. When returning to the normal mode, the processing of FIG. 3 is performed at intervals of 1 minute, for example, as a determination condition for returning to the normal mode when vibration and noise patterns are not detected, for example, when 3 consecutive times (3 minutes have passed) The operation mode may be canceled.

  The operation mode setting device 10 is preferably realized by the function of the mobile phone 1000, but is not limited thereto. Alternatively, the operation mode setting device 10 may be realized by an independent electronic circuit and connected to the mobile phone 1000 by a cable or wireless. In that case, the vibrometer 100, the microphone 200, and the camera 300 may also be realized by independent components.

  Moreover, although one Embodiment of this invention demonstrated the operation mode setting apparatus 10 applied to the mobile telephone 1000, you may apply the said operation mode apparatus to another electronic device. Examples of the electronic device include a portable game machine and a portable multimedia player.

  When the operation mode setting method according to the embodiment of the present invention described above is implemented as a program, the program is downloaded from an external server or the like to an information processing apparatus that executes the method, or is stored in a computer-readable medium. It is preferably distributed in the form. Examples of the computer readable medium include a CD-ROM, DVD, magnetic tape, flexible disk, magneto-optical disk, and hard disk.

  As mentioned above, although this invention was demonstrated using embodiment shown in drawing, these are only an illustration and those skilled in this technical field can variously be within the range which does not deviate from the range and the meaning of this invention. It will be understood that modifications and variations are possible. Accordingly, the scope of the invention should not be determined by the described embodiments, but by the technical spirit described in the claims.
