  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

  First, the technical idea of the information processing terminal according to the present embodiment will be described. The information processing terminal according to the present embodiment is realized by, for example, a smartphone, a tablet terminal, a mobile phone, a laptop personal computer, or other terminals having a positioning function.

  More specifically, the information processing terminal according to the present embodiment uses a GPS (Global Positioning System), an acceleration sensor, and other position detection devices, and the user of the information processing terminal exists in a train or other vehicle. It is judged whether it is moving or not. The information processing terminal determines from the detected position information and route information (or route information) whether there is a danger (shake) at the next position where the user heads. The route information and other route information are stored in the memory of the information processing terminal, or are stored in another information processing apparatus with which the information processing terminal can communicate.

  Furthermore, the information processing terminal uses a built-in sensor to determine whether or not the user holds the information processing terminal with both hands. If it is determined that the user holds the information processing terminal with both hands, the information processing terminal will be exposed to risks such as shaking due to a curve, shaking due to a change in the direction of travel by traveling on a branching machine, and shaking due to a sudden stop. Notify the user. The notification mode includes, for example, screen display on the monitor of the information processing terminal, output of sound, oscillation operation by a vibrator, and the like.

  In order to determine whether or not the user holds the information processing terminal with both hands, for example, a grip sensor used in an off-the-shelf product or an LCD (Liquid Crystal Display) sensor of the information processing terminal having a narrow frame Etc. can be used.

  For example, if the user is in a bus, train or other vehicle, there may be a need to notify the user that the vehicle will swing after a while and should be caught in a strap. In this case, it is possible to notify the user from the information on the dangerous position, but it may be an unnecessary notification for the user who is already held by the strap. As a result, the user may feel uncomfortable. In addition, a user who operates the information processing terminal with both hands often wears an earphone, and the user may not hear a pre-broadcast performed on a train or the like. Further, even if the user listens to the broadcast, the user may concentrate on the operation of the information processing terminal, and thus the situation where the content of the broadcast cannot be grasped may occur.

  However, according to the information processing terminal according to the present embodiment, the presence of danger or the like is notified to the user when the operation is performed with both hands, so that the user can be prevented from feeling uncomfortable. .

  In other aspects, the user may be standing or sitting. In this case, for example, when the user wears a detection device such as a wearable sensor, the information is output with both hands when standing or sitting based on the output from the detection device. Even if the processing terminal is operated, notification may not be performed.

[System Overview]
With reference to FIG. 1, a usage mode of information processing terminal 100 according to the present embodiment will be described. FIG. 1 is a diagram showing an outline of a system configuration in which an information processing terminal is used.

  In one aspect, the information processing terminal 100 can communicate with the information processing apparatus 120 via the web (Internet) 101. The information processing apparatus 120 has checkpoint information 121 that is dangerous place information on railway lines, roads, and the like. The check point information 121 includes, for example, coordinate values and data indicating a dangerous state (for example, a curve, passage on a branching machine, downhill, dead end, etc.). The information processing apparatus 120 can transmit checkpoint information 121 to the storage 110.

  The storage 110 includes a data storage area associated with the information processing terminal 100. In one aspect, the storage 110 may be a built-in memory of the information processing terminal 100. In another aspect, the storage 110 may be a storage device on a network to which the information processing terminal 100 can be connected.

  In another aspect, the check point information 121 is stored in the storage 110 in the information processing terminal 100, for example. In another aspect, the checkpoint information 121 can be transmitted from the information processing apparatus 120 to the information processing terminal 100 via the Internet 101. In yet another aspect, the information processing terminal 100 can acquire the checkpoint information 121 from broadcast radio waves (regional FM (Frequency Modulation), data broadcast, etc.).

[Checkpoint]
With reference to FIG. 2, the situation where the information processing terminal 100 is used will be described. FIG. 2 is a diagram illustrating the relationship between the check point and the current position.

  In one aspect, the user of the information processing terminal 100 is on a train. It is assumed that the train is present at the current position 210. At this time, the information processing terminal 100 detects that the information processing terminal 100 is present at the current position 210 using a GPS or other positioning function. In response to the detection of the current position 210, the information processing terminal 100 identifies the route on which the train travels. For example, the information processing terminal 100 performs a plurality of positionings within a predetermined time, and estimates the movement route of the information processing terminal 100 based on the results of each positioning. More specifically, the information processing terminal 100 searches for a travel route based on the built-in map information or map information acquired from the outside.

  The information processing terminal 100 detects the check point 220 from the searched travel route (route). For example, the information processing terminal 100 detects the check point 220 based on curve information associated with the travel route. Alternatively, the information processing terminal 100 specifies the check point 220 closest to the current position 210 from one or more check point information associated in advance with the travel route. Note that the information associated with the travel route is not limited to the curve information, and may be information indicating the presence of a branching device, a traffic light, or the like.

  Furthermore, the information processing terminal 100 uses the distance from the current position 210 to the check point 220 and the moving speed of the information processing terminal 100 to calculate the time until the information processing terminal 100 reaches the check point 220 from the current position 210. calculate. For example, the information processing terminal 100 calculates the time from the road and the latest moving speed of the information processing terminal 100. Alternatively, in another aspect, the time information of a train traveling on the road (for example, the required time between two stations including the current position 210 and the checkpoint 220) and the coordinate values of the current position 210 and the checkpoint 220 Based on this, the time is calculated.

  Whether or not the user of the information processing terminal 100 exists in the vehicle is determined based on the degree of matching between the positioning result by GPS and the route map and other route information. Alternatively, in another aspect, it may be determined that the information processing terminal 100 is present in the moving vehicle from the acceleration information of the information processing terminal 100 and the movement information of the positioning result (position information) by GPS. In yet another aspect, whether or not the information processing terminal 100 is present in the vehicle is determined based on position information used when providing a WiFi (Wireless Fidelity) service and a result of indoor positioning (radio waves, non-audible sound). It may be judged.

[Detection of holding status of information processing terminal]
When the information processing terminal 100 determines that the check point 220 is approaching, the information processing terminal 100 determines the holding state of the information processing terminal 100 by the user. More specifically, the information processing terminal 100 determines whether the user holds the information processing terminal 100 with both hands or with one hand as the holding state.

  Therefore, with reference to FIG. 3, the determination of whether or not the information processing terminal 100 is held with both hands will be described. FIG. 3 is a diagram illustrating the appearance of the information processing terminal 100. The information processing terminal 100 includes side sensors 310 and 320 on the side surface of the housing.

  The side sensors 310 and 320 detect an area held by the user on the side surface of the housing (for example, an area in which fingers are in contact). The information processing terminal 100 detects the attitude of the information processing terminal 100 using a gyro sensor (not shown). Further, the information processing terminal 100 determines whether the user holds the information processing terminal 100 with one hand or both hands using the contact area and the posture.

[Detection status of side sensor]
With reference to FIGS. 4 and 5, detection of the holding state by the side sensors 310 and 320 will be further described. FIG. 4 is a diagram illustrating a case where the user holds information processing terminal 100 with his / her hand as an aspect of holding both hands.

  In one aspect, the user may hold the information processing terminal 100 using both hands. In this case, the thumb of each hand is arranged so as to be able to touch the touch panel. The user puts the casing of the information processing terminal 100 between the thumb and the index finger, middle finger, ring finger, and little finger. At this time, a part of the index finger can come into contact with the side surface of the housing of the information processing terminal 100. In this case, for example, the output of the side sensor 310 is shown as a graph 410. The output of the side sensor 320 is shown as a graph 420. When the user holds the information processing terminal 100, the front side is often held, and as is apparent from the graphs 410 and 420, the sensor sensitivity is output from the front side surface of the information processing terminal 100. Tend to be larger. When the side sensors 310 and 320 detect an output exceeding a preset threshold value, the information processing terminal 100 determines that the user holds the information processing terminal with both hands.

  FIG. 5 is a diagram illustrating a case where the user holds the four corners of the information processing terminal as another mode of holding both hands. In this case, the user holds the information processing terminal 100 using the thumb and index finger of both hands. The side sensors 310 and 320 output signals from regions held in the vicinity of the four corners of the information processing terminal 100 as shown in the graphs 510 and 520. When the information processing terminal 100 detects that signals exceeding the preset threshold value are detected in two places in the output from the side sensor 310, the information processing terminal 100 holds the signals in two places (that is, each thumb of both hands). Judge that When the information processing terminal 100 detects that signals exceeding the preset threshold value are detected in two places in the output from the side sensor 320, the information processing terminal 100 holds the signals in two places (that is, the index fingers of both hands). Judge that In this way, the information processing terminal 100 detects that the user holds the information processing terminal 100 with both hands.

  The side sensors 310 and 320 can be realized by, for example, a capacitance sensor, a pressure sensor, or the like. The side sensors 310 and 320 may be provided on the upper and lower ends (front and back side surfaces) of the information processing terminal 100 instead of the left and right side surfaces of the information processing terminal 100. Alternatively, in another aspect, the information processing terminal 100 may determine a state in which the information processing terminal 100 is held (a shape of the contact area) based on an output signal from a sensor provided in the monitor.

  In the aspect, the gyro sensor is used for the vertical / horizontal determination of the information processing terminal 100, but other configurations may be used for the vertical / horizontal determination. Further, the determination of the holding state is not limited to the determination using the detection results by the side sensors 310 and 320. For example, when the information processing terminal 100 is large enough to be difficult to hold with one hand, or when it is heavy, the information processing terminal 100 determines that the user depends on the state of the information processing terminal 100 based on the specification information. You may presume that you hold it with both hands. In another aspect, when the information processing terminal 100 is in the horizontal direction, the information processing terminal 100 may determine that the information processing terminal 100 is held with both hands.

  In still another aspect, an external device other than the information processing terminal 100 may determine the holding state of the information processing terminal 100. For example, a method in which a user wears a wearable device on his / her waist or head and detects the posture of the human body may be used. Alternatively, the camera installed inside the vehicle may photograph a user who has the information processing terminal 100, and the attitude of the information processing terminal 100 may be detected from the image. Based on the detection result, the external device may notify the information processing terminal 100 that the user holding the information processing terminal 100 is in a dangerous state. This makes it possible to determine not only whether the user holds the information processing terminal 100 with both hands but also whether he / she is sitting, so that the notification to the user of the information processing terminal 100 is further minimized. Can be.

[Notification mode]
A mode in which the information processing terminal 100 notifies the user of the danger will be described with reference to FIGS. 6 and 7. FIG. 6 is a diagram showing a screen of monitor 610 when monitor 610 of information processing terminal 100 is held by the user in a vertically long state. FIG. 7 is a diagram illustrating a screen of monitor 610 when monitor 610 of information processing terminal 100 is held by the user in a horizontally long state.

  In a certain situation, when the user is operating the information processing terminal 100 with both hands on a traveling train, the information processing terminal 100 detects that the check point 220 is approaching, and the monitor 610 will “judge immediately. Is displayed. When the user recognizes the message 620, the user is caught on the strap of the train. As a result, even if the train shakes when passing through the check point 220, the user's feet are less likely to wobble.

  In addition, the aspect which notifies a user of danger is not restricted to what is shown by FIG. 6 and FIG. For example, the display is not limited to the display of an image or message on the monitor 610, and sound, vibration, or light may notify the user of the danger. For example, in another aspect, a speaker of the information processing terminal 100 may output a message as voice. In another aspect, the information processing terminal 100 may vibrate. In another aspect, an LED (Light Emitting Diode) or other light emitting device (not shown) included in the information processing terminal 100 may be lit.

  The notification is performed when, for example, it is detected that the information processing terminal 100 is moving a certain time before the time when the next check point is reached, but the notification is performed at other timings. May be. Further, the number of notifications of the presence of the same checkpoint is not limited to one, and a plurality of notifications may be intermittently performed.

[Function configuration]
With reference to FIG. 8, the configuration of information processing terminal 100 according to the present embodiment will be further described. FIG. 8 is a block diagram showing functions provided in the information processing terminal 100. The information processing terminal 100 includes a control unit 810, a communication unit 820, an antenna 821, a position information acquisition unit 830, a storage unit 840, a situation determination unit 850, a notification unit 860, and a side touch detection unit 870. Prepare.

  Control unit 810 controls the operation of information processing terminal 100 based on data and programs stored in information processing terminal 100. The control unit 810 is realized by a processor, for example.

  The communication unit 820 communicates with other information processing terminals and the information processing apparatus 120 via the antenna 821. The communication unit 820 is realized by a circuit according to a known communication technology.

  The position information acquisition unit 830 receives the positioning signal transmitted by each of at least three GPS satellites, and derives the coordinate position of the information processing terminal 100 from each positioning signal. The position information acquisition unit 830 is realized as a dedicated processor having a positioning calculation function, for example. In another aspect, the position information acquisition unit 830 may be incorporated in a processor that implements the control unit 810. In still another aspect, the position information acquisition unit 830 may specify the position of the information processing terminal 100 using a WiFi access point. In another aspect, the position information acquisition unit 830 is realized by an A-GPS (Assisted GPS), an acceleration sensor, a gyro sensor, an IMES (Indoor MEssaging System), and the like in addition to the GPS.

  The storage unit 840 holds data and programs that define the operation of the information processing terminal 100. The storage unit 840 is realized by a ROM (Read-Only Memory), a RAM (Random Access Memory), a flash memory, a removable nonvolatile data recording medium, and the like.

  The situation determination unit 850 uses the coordinate position of the information processing terminal 100 detected by the position information acquisition unit 830 and the map information stored in the storage unit 840 to determine whether the information processing terminal 100 is moving. Determine whether. In another aspect, situation determination unit 850 determines whether or not information processing terminal 100 is operated with both hands of the user, based on the output from side touch detection unit 870. The situation determination unit 850 is realized, for example, by executing a program configured to realize the determination process by the processor. The processor may be the same as or different from the processor that realizes the control unit 810.

  The notification unit 860 notifies the user that the information processing terminal 100 is approaching a dangerous position such as the check point 220. The notification unit 860 is realized by a monitor 610, a speaker (not shown), a vibrator (not shown), and the like.

  The side touch detection unit 870 detects whether or not the side surface of the information processing terminal 100 is operated. The side touch detection unit 870 is realized by, for example, side sensors 310 and 320 disposed on the side surface of the housing of the information processing terminal 100. The side sensors 310 and 320 include, for example, an electrostatic sensor, a pressure sensor, etc., but other sensors may be used.

[Control structure]
The control structure of the information processing terminal 100 will be described with reference to FIGS. FIG. 9 is a flowchart showing a part of processing executed by control unit 810 of information processing terminal 100.

  In step S910, control unit 810 acquires checkpoint 220 and area information via communication unit 820, and stores the acquired data in storage unit 840. In addition, when there is checkpoint information on the Internet (for example, when the information processing apparatus 120 holds the checkpoint information), the information processing terminal 100 uses WiFi, 3G (generation), LTE (Long Term). Evolution) Obtain checkpoint information using other communication networks. When the checkpoint is in a PC (Personal Computer) or other device, the information processing terminal 100 can acquire information on the checkpoint via a USB (Universal Serial Bus) cable, a LAN, or other communication path.

  In step S920, control unit 810 acquires position information of the current location of information processing terminal 100 based on the output from position information acquisition unit 830. For example, the control unit 810 acquires position information at regular time intervals.

  In step S930, control unit 810 predicts the movement state of information processing terminal 100 based on the change in position information of the current location and area information. For example, the control unit 810 estimates a future moving location of the information processing terminal 100 from the position information and time information held in the storage unit 840. Since the storage unit 840 holds time information and position information, the control unit 810 can know the movement status around the current time, and Mt minutes after the movement speed and movement direction immediately before the information processing terminal 100. Is estimated.

  In step S940, control unit 810 determines whether or not information processing terminal 100 is approaching checkpoint 220 after Mt minutes, based on the area information and the latest position information. In another aspect, for example, the control unit 810 calculates the distance between the check point 220 and the current position of the information processing terminal 100 at regular intervals, and if the distance is shorter, the information processing terminal 100 It is determined that the check point 220 is approaching. When control unit 810 determines that information processing terminal 100 is approaching check point 220 (YES in step S940), control unit 810 switches control to step S950. If not (NO in step S940), control unit 810 returns control to step S920.

  In step S950, control unit 810 determines whether or not information processing terminal 100 is held by both hands of the user, based on the output from side touch detection unit 870. If control unit 810 determines that information processing terminal 100 is held by both hands, control unit 810 switches control to step S960. Otherwise, control unit 810 returns control to step S920.

  In step S960, control unit 810 notifies the user of the danger based on approaching checkpoint 220. For example, the information processing terminal 100 displays on the monitor 610 a message 620 that prompts the user to hold onto a strap in preparation for shaking due to running on a curve (FIGS. 6 and 7).

[When movement is not predicted]
In another aspect, information processing terminal 100 may determine approach to checkpoint 220 without performing movement prediction.

  Therefore, with reference to FIG. 10, a control structure when movement prediction is not performed will be described. FIG. 10 is a flowchart showing a part of processing executed by control unit 810 of information processing terminal 100 that does not perform movement prediction. A part of the same processing as that shown in FIG. 9 is not shown.

  In step S920, control unit 810 acquires position information of the current location of information processing terminal 100 based on the output from position information acquisition unit 830. For example, the control unit 810 acquires position information at regular time intervals. Control is transferred to step S1040.

  In step S1040, control unit 810 determines whether there is a checkpoint within the Dkm range from the current location of information processing terminal 100. For example, the control unit 810 compares the current position information acquired in step S920 with the position information of the checkpoint 220 acquired in step S910, and is within a predetermined range from the current location of the information processing terminal 100 (for example, It is determined whether there is a check point within the radius Dkm). When control unit 810 determines that there is a check point within the Dkm range from the current location (YES in step S1040), control unit 810 switches control to step S950. If not (NO in step S1040), control unit 810 returns control to step S920.

  Even in this case, the information processing terminal 100 can detect the approach of the checkpoint, and accordingly can notify the user of the danger as appropriate.

[Combination of movement prediction and other information]
In yet another aspect, the information processing terminal 100 can detect the approach of the checkpoint by combining the movement prediction and other information.

  Then, with reference to FIG. 11, the approach of the checkpoint in another situation is demonstrated. FIG. 11 is a flowchart showing a part of processing executed by the control unit 810 of the information processing terminal 100 that can notify the approach of the checkpoint by combining the movement prediction and other information. A part of the same processing as that shown in FIG. 9 is not shown.

  In step S920, control unit 810 acquires position information of the current location of information processing terminal 100 based on the output from position information acquisition unit 830. For example, the control unit 810 acquires position information at regular time intervals.

  In step S1110, control unit 810 acquires peripheral information on the current location of information processing terminal 100 via communication unit 820, and stores the acquired information in storage unit 840. The peripheral information is, for example, a route map, operation information, etc., but may include other information.

  In step S1120, control unit 810 estimates the movement route of information processing terminal 100 using position information, time information, and peripheral information held in storage unit 840. For example, when a route map is given to the information processing terminal 100 as the peripheral information, the movement route of the information processing terminal 100 is fixed, so that the control unit 810 estimates the position of the information processing terminal 100 after Mt seconds. Compared to the case of FIG. 9 or FIG. 10, the position can be estimated with higher accuracy. In addition, when the information processing terminal 100 is able to acquire operation information (required time of a section), when there is no checkpoint by the next section, the information processing terminal 100 checks while it exists in the section. It is not necessary to determine whether or not there are points. As a result, the processing is simplified, and the burden on the control unit 810 is reduced. Thereafter, control is transferred to step S940.

  As described above, the information processing terminal 100 according to the present embodiment uses the position information, the map information, and the estimated position, and there is a checkpoint or other dangerous place on the moving route of the information processing terminal 100. Judge whether or not. When it is detected that a dangerous place is approaching, the information processing terminal 100 alerts the user when determining that the user holds the information processing terminal 100 with both hands. For example, monitor 610 displays message 620. Thereby, danger can be notified without giving discomfort to a user.

  Note that in another aspect, notification by the monitor 610 of the information processing terminal 100 may be performed by a command of the information processing device 120. That is, the information processing apparatus 120 executes the above-described process executed in the information processing terminal 100 and detects that the information processing terminal 100 is approaching the check point 220. In response to the detection, the information processing device 120 notifies the information processing terminal 100 of a signal indicating that the information processing terminal 100 is approaching the check point 220. When the information processing terminal 100 receives the signal, the information processing terminal 100 displays a message 620 on the monitor 610. In this way, the amount of processing by the information processing terminal 100 is suppressed, so that the operation of the information processing terminal 100 can be lightened.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
