Abstract

When an object is in contact with and exerting pressure on this terminal device, the terminal device carries out appropriate information processing in which a measured atmospheric pressure value is treated as an atmospheric pressure value measured in a state in which pressure is being exerted. This terminal device (1) is provided with a contact state detection unit (12) for detecting contact between the terminal device (1) and an object, a sensor control unit (11) for using an atmospheric pressure sensor (20) to measure an atmospheric pressure value, and an information processing unit (16) for carrying out information processing using the measured atmospheric pressure value and outputting the result of the information processing. If contact between the terminal device (1) and an object has been detected, the sensor control unit (11) changes the way in which the atmospheric pressure value is output to the information processing unit (16). The information processing unit (16) uses the atmospheric pressure value output in the changed way for information processing if contact between the terminal device (1) and the object has been detected.

2. Description of the Related Art In recent years, among portable terminals, those incorporating a barometric pressure sensor are increasing. However, in a terminal with a highly airtight structure such as a waterproof compatible terminal, the internal pressure temporarily changes even when physical pressure is externally applied to the terminal, and a measurement value different from the actual atmospheric pressure is obtained.

Japanese patent publication "Japanese Unexamined Patent Publication No. 2015-122649 (July 2, 2015 published)"

However, even if the terminal is not operated, situations where pressure is applied to the terminal vary. For example, pressure is also applied to the terminal when walking while holding the terminal in the pocket of the pants. Also in this case, there is no problem if only the barometric pressure value at the measurement moment is obtained, but, for example, when the barometric pressure value is continuously acquired in the background, acquisition of measurement values other than the original barometric pressure value is unexpected. It is assumed to have an impact. For example, in positioning, navigation, and communication functions that use altitudes calculated from barometric pressure values, there is a problem in that false information indicating that they are present at incorrect altitudes is transmitted. That is, conventionally, when the object is in contact and pressure is applied, nothing is considered about the viewpoint of appropriately processing the measured air pressure value as the air pressure value measured in the pressure applied state. There is a problem that was not done.

The terminal device and the like according to one aspect of the present invention has been made in view of the above problems, and its object is to measure the barometric pressure value measured when an object is in contact and pressure is applied, An object of the present invention is to realize a terminal device or the like that can appropriately process information as an atmospheric pressure value measured in a state where pressure is applied.

When the contact between the terminal device and the object is detected, the output form of the air pressure value to the information processing unit is changed, and the information processing unit detects the contact between the terminal device and the object In this case, the information processing is performed using the atmospheric pressure value whose output form has been changed.

In order to solve the above-mentioned subject, a control method of a terminal unit concerning one mode of the present invention is a control method of a terminal unit which has a function which measures barometric pressure value, and detects a contact with the above-mentioned terminal unit and object And a pressure measurement step of measuring a pressure value using a pressure sensor, and an information processing step of performing information processing using the measured pressure value and outputting the result of the information processing. When the contact between the terminal device and the object is detected, the output form of the atmospheric pressure value measured in the atmospheric pressure measurement step is changed, and the atmospheric pressure value whose output form is changed in the information processing step is used. It is characterized in that information processing is performed.

According to the terminal device or the control method thereof according to one aspect of the present invention, when the object is in contact and pressure is applied, the measured air pressure value is used as the air pressure value measured in a state where the pressure is applied. An effect is obtained that information processing can be properly performed.

Hereinafter, for the sake of convenience of explanation, the same symbols may be added to the other items for the components having the same functions as the components described in the certain items, and the description thereof may be omitted.

[Outline of installation status of pressure sensor and background of problems]
In recent years, there are an increasing number of models equipped with the "pressure sensor" in mobile terminals such as smartphones. At present, the scene utilizing the barometric pressure sensor, that is, the application is as follows.
(1) A display of the atmospheric pressure value of the present location.
(2) A display of the altitude (calculated from the pressure value) of the present location.
(3) As an activity meter, it displays "the number of floors which went up the hierarchy of a building" from the fluctuation of barometric pressure value (how many floors went up).
(4) A device such as indoor navigation using PED (Pedestrian Dead Reckoning) that estimates how many floors of a building have been moved.
(5) Those utilizing barometric pressure values in emergency call positioning (in the case of a disaster in a building, those that notify which floor they are on by the barometric pressure values).

In addition, sensors such as barometric pressure sensors basically use the concept of Always-On (always operate), and the sensors always operate even during periods when the user is not operating or displaying It is thought that the usage of continuing will increase in the future.

Use a barometric pressure sensor to detect movement between floor levels in indoor navigation that does not use GPS (Global Positioning System) or record the level movement by fitness, and use the barometric pressure value to move the levels It is detected.

At this time, for example, when the portable terminal is put in the front pocket of the pants, the portable terminal may be pressed by the foot when going up the stairs, and the instantaneous pressure value may be detected as the barometric pressure value. For this reason, there is a possibility of detecting a hierarchical change which is not going up.

By using the terminal device 1 described below, for example, while it is possible to see or mitigate fluctuations in barometric pressure value while putting in the front pocket of the pants, it is possible to detect an erroneous hierarchy change. It is possible to use the pressure value with high accuracy.

[Outline of Internal Structure of Terminal Device 1]
In FIG. 2, the outline of the internal structure of the terminal device 1 which concerns on one Embodiment of this invention is shown. The terminal device 1 is a waterproof compatible terminal, and is provided with waterproof performance (airtightness) by sealing the outer peripheral portion of the housing of the terminal device 1 with a waterproof tape, rubber, an adhesive, or the like.

However, if the case is completely sealed, the pressure values inside and outside the case are different. Therefore, the pressure value inside the case is made equal to the outside by providing a venting film described later. The venting membrane is a membrane that allows only air to pass through without passing moisture. By means of the venting membrane, the pressure value inside and outside the housing can be kept equal while maintaining waterproofness.

When rapid physical pressure is applied to the housing, the air inside the housing moves to the outside through the venting membrane. However, the pressure inside the housing temporarily rises at the moment when pressure is applied, because the air-permeable membrane has certain conditions (the amount of air flow per unit time is fixed) in air permeability compared to a completely open hole. Then, the air comes out through the venting membrane and becomes equal to the external pressure (see FIG. 3).

[Configuration of terminal device]
FIG. 1 is a block diagram showing the configuration of the terminal device 1. As described above, the terminal device 1 is a terminal device having a function of measuring the barometric pressure value. As shown in the figure, the terminal device 1 includes a control unit 10, an air pressure sensor 20, a proximity sensor 40, an acceleration sensor 41, a timer 50, a storage unit 60, and a display unit 70.

The control unit 10 controls each part of the terminal device 1 in an integrated manner. As shown in FIG. 1, the control unit 10 includes a sensor control unit 11, a contact state detection unit (contact detection unit) 12, a recording control unit 13, a display control unit 14, a reliability setting unit 15, and an information processing unit 16. Have.

The sensor control unit 11 measures an air pressure value using the air pressure sensor 20. The sensor control unit 11 also controls the operation of the barometric pressure sensor 20 and the filter 30. The sensor control unit 11 further includes a filter 30 and a measurement value acquisition unit 111, and acquires information related to an air pressure value generated based on a detection signal of the air pressure sensor 20. Further, when the contact between the terminal device 1 and the object is detected, the sensor control unit 11 changes the output form of the barometric pressure value to the information processing unit 16.

For example, the sensor control unit 11 changes the coefficient of the filter 30 according to whether or not the contact between the terminal device 1 and the object is detected. Specifically, the coefficients of the filter 30 are switched to the hard mode or the normal mode.

The filter 30 has a function of smoothing (relaxing) a change in the measured air pressure value, and is configured by, for example, an LPF (low pass filter) or the like. Switching the filter 30 to the hard mode or the normal mode is, for example, to turn the filter 30 on or off or to switch the coefficients of the filter 30 to be steep or gentle.

When the contact between the terminal device 1 and the object is detected, the sensor control unit 11 turns on the filter 30. On the other hand, when the contact between the terminal device 1 and the object is not detected, the sensor control unit 11 turns off the filter 30.

The barometric pressure sensor 20 measures a barometric pressure value. Also, by passing the filter 30 in order to reduce noise (excessive response value) at the time of measurement value measurement by the air pressure sensor 20, fine fluctuation of the measured air pressure value is reduced, and a relatively stable air pressure value can be obtained. It becomes possible to acquire.

As shown in FIG. 5, the measured value of the air pressure measured through the filter 30 (in this embodiment, the LPF) is the measured value of the air pressure when the filter 30 is not applied (see the thin solid line graph). On the other hand, relatively gradual change (see thick solid line graph). The graph shown in FIG. 5 shows the result of measuring the barometric pressure value when pressure was applied to the housing of the terminal device 1 in a pseudo manner (five times). The measurement of barometric pressure measured through the filter 30 is smooth without any sharp changes in the measured barometric pressure without the filter 30. However, the response is delayed with respect to the timing of the change.

In the present embodiment, in the case where “a steep change is expected due to physical pressure = contact detection state”, the filter 30 is turned on to reduce the steep change while also delaying the response. It is possible to keep to a minimum.

Further, even if the sensor control unit 11 detects a contact between the terminal device 1 and an object, the sensor control unit 11 may replace the pressure value measured after the detection with the pressure value measured before the detection and output the pressure value. good. Thereby, it is possible to replace the incorrect air pressure value affected by the contact between the terminal device 1 and the object with the air pressure value measured without being affected by the contact between the terminal device 1 and the object Become.

Further, when the contact between the terminal device 1 and the object is detected, the sensor control unit 11 may output the measured atmospheric pressure value together with the reliability set lower than that before the detection. Thereby, when the contact between the terminal device 1 and the object is detected, the barometric pressure value is output together with the reliability. Therefore, it is possible to perform information processing according to the reliability on the barometric pressure value.

The contact state detection unit 12 detects a contact between the terminal device 1 and an object. More specifically, the contact state detection unit 12 determines whether or not the contact between the terminal device 1 and the object is detected. In the present embodiment, the contact state detection unit 12 adopts a configuration that uses the proximity sensor 40 to determine whether an object is in contact with the terminal device 1, but the present invention is not limited to such a configuration. . For example, an electrostatic sensor, a touch panel or the like may be used to detect that an object is in contact with the terminal device 1. Further, the same effect can be obtained by detecting that a force is applied to the terminal device 1 using a strain sensor, a pressure sensor or the like.

Further, the state in which the contact is detected can be assumed to be a state in which the housing of the terminal device 1 has a possibility of being applied with any force. Conversely, it is not easy to apply physical pressure to the terminal device 1 from the outside without any object in contact with it. As the arrangement position of the proximity sensor 40, at least one proximity sensor 40 is provided on at least one surface (for example, a display surface) of the housing of the terminal device 1. It is desirable that the surface on which the proximity sensor 40 is disposed is a surface (or a facing) that is susceptible to being pushed by the housing.

The recording control unit 13 performs control to record the barometric pressure value acquired by the sensor control unit 11 in the storage unit 60. Further, the recording control unit 13 stores the measured barometric pressure value in the storage unit 60 in association with the measured time.

The display control unit 14 controls the display by the display unit 70. When the contact between the terminal device 1 and the object is detected, the reliability setting unit 15 sets that the reliability of the measured air pressure value is low, and when the contact between the terminal device 1 and the object is not detected. Set the measured pressure value high reliability.

The information processing unit 16 performs information processing using the barometric pressure value output from the sensor control unit 11, and outputs the result of the information processing to the display control unit 14. For example, the information processing unit 16 uses the barometric pressure value output from the sensor control unit 11 to calculate the altitude of the place where the terminal device 1 is present.

The proximity sensor 40 and the acceleration sensor 41 are sensors for detecting contact of an object. The timer 50 measures the time at which the pressure value is measured, and the like. The storage unit 60 stores the measured barometric pressure value in association with the measured time and the like. The display unit 70 uses, for example, a liquid crystal panel. However, the display panel used for the display unit 70 is not limited to the liquid crystal panel, and may be an organic EL (electroluminescence) panel, an inorganic EL panel, a plasma panel or the like.

(Function and effect of the terminal device 1)
According to the terminal device 1, the contact state detection unit 12 detects a contact between the terminal device 1 and an object. In general, when the terminal device 1 and an object are in contact with each other, the terminal device 1 is in a state in which pressure may be applied from the outside. For this reason, it can be estimated that pressure is applied to the terminal device 1 by detecting the contact between the terminal device 1 and the object. Further, according to the terminal device 1, the sensor control unit 11 changes the output form of the barometric pressure value to the information processing unit 16 when the contact between the terminal device 1 and the object is detected. Thereby, when the terminal device 1 and the object are in contact and pressure is applied, it is possible to set the output form of the pressure value to be measured according to the pressure applied state. As described above, according to the terminal device 1, when the object is in contact and pressure is applied, the measured air pressure value can be properly processed as the air pressure value measured in the pressure applied state. it can.

According to the above configuration, the contact detection unit detects the contact between the terminal device and the object. In general, when an object is in contact with a terminal, the terminal is in a state in which external pressure may be applied. Therefore, by detecting the contact between the terminal device and the object, it can be estimated that the terminal device is under pressure. Further, according to the above configuration, the sensor control unit changes the output form of the barometric pressure value to the information processing unit when the contact between the terminal device and the object is detected. Thereby, when the terminal device and the object are in contact and pressure is applied, it is possible to set the output form of the pressure value to be measured according to the pressure applied state. As described above, according to the above configuration, when the object is in contact and pressure is applied, the measured air pressure value can be properly processed as the air pressure value measured in the pressure applied state. .

It may replace with the above-mentioned atmospheric pressure value measured before detection, and may output. According to the above configuration, when the contact between the terminal device and the object is detected, the atmospheric pressure value measured after the detection is replaced with the atmospheric pressure value measured before the detection and output. This makes it possible to replace the incorrect air pressure value affected by the contact between the terminal device and the object with the air pressure value measured without being affected by the contact between the terminal device and the object.
