  The portable device 100 according to the first embodiment of the present invention has a wristwatch type (or wristband type) external shape that is worn on a user's wrist USh as shown in FIGS. 1 (a) and 1 (b), for example. Have. For example, as shown in FIGS. 1A and 1B, the mobile device 100 is roughly divided and wrapped around a device main body 101 including a display unit 120 for providing a user with predetermined information and a wrist USh of the user. Thus, a belt portion 102 for attaching the device main body 101 to the wrist USh is provided. 1A is a diagram illustrating a state in which the mobile device 101 is mounted on the wrist USh so that the device main body 101 is positioned on the back side of the user's hand, and FIG. It is a figure which shows the state which mounted | wore the wrist USh with the portable apparatus so that it may be located on the palm side of the hand.

  Specifically, for example, as shown in FIG. 2, the mobile device 100 includes a three-dimensional acceleration sensor 110, a display unit 120, a light emitting unit 130, an operation unit 140, an arithmetic circuit (a microprocessor unit; 150, abbreviated as “MPU”), a memory 160, a timer circuit 170, and a power supply unit 180.

  The three-dimensional acceleration sensor (or the three-axis acceleration sensor) 110 is a state in which a user wears the mobile device 100, for example, a rate (acceleration) of a change in moving speed applied to the mobile device 100 during walking or jogging.

These acceleration data are stored in a predetermined storage area of the memory 160 in association with time information output from the timer circuit 170.

  The display unit 120 includes a display panel such as a reflective or transmissive liquid crystal display panel capable of color or monochrome display, and displays predetermined information such as current time and exercise information at least while the user is walking or jogging. indicate. In addition, a light emitting unit 130 is provided on the front side or the back side of the display panel of the display unit 120, and light from the light emitting unit 130 is applied to the display panel. Here, when the display unit 120 includes a reflective display panel, the light emitting unit 130 is disposed as a front light on the front side of the display panel, and on the other hand, when the display unit 120 includes a transmissive display panel. The light emitting unit 130 is disposed as a backlight on the back side of the display panel. In this embodiment, the case where the display unit 120 and the light emitting unit 130 have separate configurations has been described. However, the display panel itself emits light as desired instead of the display unit 120 and the light emitting unit 130. A light-emitting display unit having a self-luminous display panel such as an organic EL display panel that displays the above information may be applied. Note that in this specification, the operation of displaying predetermined information on the display panel of the display unit 120, the operation of irradiating light from the light emitting unit 130 to the non-light emitting display panel, and the predetermined information on the self-luminous display panel. The operations for displaying are collectively referred to as “display driving” in the claims.

  The operation unit 140 includes, for example, a button switch and a slide switch as illustrated in FIGS. 1A and 1B, a touch panel disposed or integrally formed on the front side (view side) of the display unit 120, It is used for operations such as selection of various functions, input settings, and execution instructions in the mobile device 100. For example, by operating the operation unit 140, driving power is supplied (powered on) or blocked (powered off) from the power supply unit 180 to each component in the mobile device 100, a sensing operation in the three-dimensional acceleration sensor 110 is started, The stop, the display operation in the display unit 120, the turning on / off operation in the light emitting unit 130, and the like are controlled.

  The memory 160 has a non-volatile memory, and various data to be detected, generated, or referred to in relation to at least the tilt state determination process and the lighting control process of the light emitting unit 130 executed in the mobile device 100 are stored. It is stored in a predetermined storage area. Here, the memory 160 includes a control program for realizing predetermined functions in the three-dimensional acceleration sensor 110, the display unit 120, the light emitting unit 130, the memory 160, and the time measuring circuit 170, and a tilt state determination process and light emission described later. It may include a read only memory (ROM) in which an algorithm program for realizing the lighting control process of the unit 130 is stored.

  The MPU 150 controls the three-dimensional acceleration sensor 110, the display unit 120, the light emitting unit 130, and the memory 160 to execute a predetermined function by executing a predetermined control program based on the basic clock generated in the timing circuit 170. Realize. Further, the MPU 150 executes a predetermined algorithm program, thereby realizing an inclination state determination process and a lighting control process of the light emitting unit 130 applied to the control method of the portable device 100 according to the present invention. Note that these control programs and algorithm programs may be stored in the memory 160 described above, or may be incorporated in the MPU 150 in advance.

  The timer circuit 170 includes an oscillator that generates a basic clock, generates an operation clock that defines the operation timing of each component of the mobile device 100 based on the basic clock, and generates time information indicating the current time. And output. This time information is displayed on the display unit 120 as the current time, and is stored in the memory 160 in association with the acceleration data collected by the three-dimensional acceleration sensor 110 and other data. Note that this timing circuit 170 may be incorporated in the MPU 150 in advance as a timing function.

  The power supply unit 180 supplies driving power to each component inside the mobile device 100. As the power supply unit 180, a commercially available primary battery such as a coin-type battery or a button-type battery, or a secondary battery such as a lithium ion battery or a nickel metal hydride battery can be applied. In addition to these primary batteries and secondary batteries, a power source using energy harvesting technology that generates power using energy such as vibration, light, heat, and electromagnetic waves can also be applied.

(Control method for mobile devices)
Next, a method for controlling the above-described portable device will be described. Here, in a state where the user wears the portable device 100 according to the present embodiment on the wrist and is walking, jogging, or the like, when viewing information displayed on the display unit 120 of the portable device 100, A method for determining the tilt state of the mobile device 100 and a lighting control method for the light emitting unit 130 will be described.

  FIG. 3 is a flowchart illustrating an example of a control method applied to the mobile device according to the present embodiment. FIG. 4 is a schematic diagram showing vector data detected in the mobile device according to the present embodiment. FIG. 5 is a schematic diagram illustrating an example of a gravity direction vector detected in the mobile device control method according to the present embodiment, and FIG. 6 illustrates a travel direction detected in the mobile device control method according to the present embodiment. It is the schematic which shows an example of a vector. FIG. 7 is a schematic diagram illustrating an example of a direction range with respect to the gravitational direction applied to the determination process of the tilt state in the control method for the portable device according to the present embodiment, and FIG. 8 illustrates the portable device according to the present embodiment. It is the schematic which shows an example of the direction range with respect to the advancing direction applied to the determination process of the inclination state in the control method of an apparatus.

  In the method for controlling the portable device 100 according to the present embodiment, as illustrated in FIG. 3, when the portable device 100 is activated and the control process is started, the MPU 150 uses the three-dimensional acceleration sensor 110 to generate acceleration data (sensor data). It acquires sequentially with a predetermined sampling period (step S101). Specifically, when the user operates the operation unit 140 of the mobile device 100 worn on the wrist USh, the MPU 150 uses the three-dimensional acceleration sensor 110 to detect the moving speed applied to the mobile device 100 while the user is walking or jogging. A sensing operation for detecting acceleration, which is the rate of change, as acceleration data is executed. Here, the output from the three-dimensional acceleration sensor 110 is filtered by passing through a filter circuit (not shown) such as a low-pass filter, thereby causing high-frequency noise components, unintentional hand tremors and blurring of the user. Caused components are removed. The acceleration data from which the noise component has been removed is stored in a predetermined storage area of the memory 160 in association with the time information output from the timer circuit 170. The acceleration data acquisition operation may be started by the user operating the operation unit 140 as described above. For example, the acceleration data acquisition operation is started in conjunction with the activation of the mobile device 100, and thereafter , It may be always operated.

  Next, the MPU 150 analyzes the acquired acceleration data and executes a series of processes for determining the tilt state of the mobile device 100. Specifically, for example, in the portable device 100 to be worn on a specific part of the human body such as the wrist USh, the portable device 100 is used as a reference depending on the manner of wearing, the wearing state, the position and angle of the part, and the like. The direction of gravity can take various directions. Here, for example, as shown in FIG. 1A, the portable device 100 is worn such that the display surface 121 of the display unit 120 faces the back side (outside) of the wrist USh. Or, as shown in FIG. 1 (b), it is a state in which it is mounted so as to face the palm side (inside). In addition, the state of the position and angle of the part of the human body means, for example, whether the elbow is raised or lowered, stretched or bent when the mobile device 100 is worn on the wrist USh. That is.

  Therefore, in the present embodiment, the gravitational direction is derived by calculating an average of accelerations for a certain period detected by the three-dimensional acceleration sensor 110 as a vector (step S102). Furthermore, based on the acceleration data detected by the three-dimensional acceleration sensor 110, a traveling direction that is a moving direction when the user walks or jogs is derived (step S103). The acquired gravity direction and traveling direction are stored in a predetermined storage area of the memory 160 in association with the time information output from the timer circuit 170.

  Here, the traveling direction of the user is, for example, based on acceleration data acquired by the three-dimensional acceleration sensor 110 and a vertical acceleration component parallel to gravity based on an acceleration average vector and a horizontal direction orthogonal to the vertical direction ( In the horizontal plane), and when the change in the acceleration component in the horizontal direction is maximized during the period between when the change in the acceleration component in the vertical direction becomes maximum and minimum The direction of the acceleration component in the horizontal direction can be derived by a method in which the user travels in the direction of travel. The method for deriving the user's direction of travel is not limited to this method, and other detection methods may be applied as long as the output from the three-dimensional acceleration sensor is used. Further, the traveling direction of the user does not necessarily have to be in the horizontal direction orthogonal to the gravity direction (vertical direction).

  Next, the MPU 150 determines whether or not the user's direction of travel has been successfully derived in step S103 (step S104). Specifically, when the user wearing the mobile device is stationary or moving his hand violently at random, the traveling direction of the user is detected from the acceleration data detected by the three-dimensional acceleration sensor 110. Or fluctuations and variations in the detected acceleration data become large. In such a case, the traveling direction of the user cannot be detected normally, and derivation of the traveling direction fails. Therefore, in step S103, it is determined whether or not the user has succeeded in deriving the traveling direction, so that the stationary state of the user and noise contamination due to unintended movement of the user are determined, and the traveling direction is determined. The process of the lighting control method of the light emitting unit 130 described later is changed depending on whether the derivation is successful or not.

  When the gravitational direction and the traveling direction are acquired in this way, the mobile device 100 can be used as shown in FIGS. 4A and 4B, for example, depending on the tilt state of the mobile device 100 and the traveling direction of the user. The vector component (gravity direction vector) Vg in the gravity direction and the vector component (travel direction vector) Vm in the traveling direction of the user are conceptually represented.

  If the direction of travel is successfully derived in step S104, the MPU 150 determines whether or not the acquired gravity direction and travel direction are within a preset direction range (step S105). Specifically, for the gravity direction, for example, as shown in FIG. 5, orthogonal coordinates composed of three orthogonal X, Y, and Z axes are set with reference to the device main body 101 of the mobile device 100. Here, for example, assuming that the portable device 100 is a wristwatch, the 6 o'clock direction (left direction in the drawing) of the display surface 121 of the display unit 120 that is a dial is set as the positive (+) direction of the X axis, and the display surface 121 is displayed. The 3 o'clock direction (front side of the drawing) is set as the positive (+) direction of the Y axis, and the direction from the visual field side to the back side of the display surface 121 (downward direction of the drawing) is set as the positive (+) direction of the Z axis. did. That is, in the present embodiment, the XY plane including the X and Y axes of the orthogonal coordinates coincides with or is parallel to the display surface 121 of the display unit 120 of the mobile device 100 and is orthogonal to the direction perpendicular to the display surface 121. The three-dimensional acceleration sensor 110 is arranged so that the Z axis of the coordinates coincides or is parallel.

  In this coordinate system, with respect to the gravity direction, as shown in FIG. 5, the angle (pan angle) from the positive direction of the X axis to the positive direction of the Y axis in the XY plane is defined as α, XY plane. An angle (tilt angle) from the direction toward the positive direction of the Z-axis is set to β. In this case, the acquired gravity direction (that is, the gravity direction vector Vg) is represented by polar coordinates (α, β).

  As for the traveling direction, for example, as shown in FIG. 6, orthogonal coordinates similar to the gravity direction described above are set, and in this coordinate system, the positive direction of the Y axis from the positive direction of the X axis in the XY plane. Is set to θ, and the angle (tilt angle) from the XY plane toward the positive direction of the Z axis is set to φ. In this case, the acquired traveling direction (that is, the traveling direction vector Vm) is represented by polar coordinates (θ, φ). Here, the radius of the sphere shown in FIGS. 5 and 6 represents the magnitude of acceleration. In FIG. 5 showing the direction of gravity, the radius is constant, and in FIG. 6 showing the direction of travel, the radius changes according to the magnitude of acceleration, and the radius is 0 when the user is stationary. The traveling direction is not derived.

  For each of these four parameters α, β, θ, and φ, a direction range consisting of a lower limit and an upper limit is set in advance and stored in a predetermined storage area of the memory 160, and the direction range is referred to by referring to the direction range. Then, it is determined whether or not the polar coordinates angles α and β representing the acquired gravity direction and the acquired polar coordinate angles θ and φ representing the traveling direction are within the respective direction ranges. Here, with respect to the direction of gravity, for example, as shown in FIG. 7, the angle that becomes the lower limit value of the angle α is set to a, the angle that becomes the upper limit value is set to A, the angle that becomes the lower limit value of the angle β is set to b, A direction range DR1 formed by setting the value angle to B is set in advance as a criterion for determining the direction of gravity and stored in a predetermined storage area of the memory 160. Then, the MPU 150 is defined when the polar coordinates α and β representing the acquired gravity direction satisfy the conditions of a <α <A and b <β <B, that is, the angles α and β. When the end point of the gravity direction vector Vg is within the direction range DR1, it is determined that the acquired gravity direction is the true gravity direction.

  For the traveling direction, for example, as shown in FIG. 8, the angle serving as the lower limit value of the angle θ is set to h, the angle serving as the upper limit value is set to H, the angle serving as the lower limit value of the angle φ is set to f, and the upper limit value. A direction range DR2 formed by setting the angle to be F to be set in advance as a criterion for determination of the traveling direction is stored in a predetermined storage area of the memory 160. Then, the MPU 150 is defined when the polar coordinate angles θ and φ representing the obtained traveling direction satisfy the conditions of h <θ <H and f <φ <F, that is, the angles θ and φ. When the end point of the traveling direction vector Vm is within the direction range DR2, it is determined that the acquired traveling direction is a true traveling direction.

  And MPU150 performs the lighting control process of the light emission part 130 based on the determination result whether the acquired gravity direction and advancing direction satisfy | fill said conditions. That is, in the case where all the above conditions are satisfied for each of the acquired gravity direction and traveling direction, the MPU 150 can visually recognize the information displayed on the display unit 120 of the mobile device 100 worn by the user. It is determined that the mobile device 100 has been operated so as to be in a predetermined tilt state, and the light emitting unit 130 is turned on for a preset time to illuminate the display unit 120 (step S106). Here, the lighting time of the light emitting unit 130 is set to an arbitrary time such as 2 seconds or 7 seconds, for example. Then, after the lighting of the light emitting unit 130 is completed for a predetermined time, the MPU 150 determines whether or not to end a series of control processes (step S107). If not, the MPU 150 returns to step S101 and repeats the above. A series of control processes are sequentially executed.

  On the other hand, if the direction of travel has not been successfully derived in step S104, the MPU 150 determines whether or not the mobile device 100 is stationary (step S108). When it is determined that the mobile device 100 is stationary, the MPU 150 determines that the user is in a state where the user has stopped walking or jogging, for example, and uses only the acquired gravity direction to emit the light emitting unit 130. The lighting control process is executed (step S109). That is, the MPU 150 determines that the polar coordinates angles α and β representing the acquired gravity direction satisfy a predetermined condition, or the end point of the gravity direction vector Vg defined by the angles α and β is within the predetermined direction range. In this case, it is determined that the acquired gravity direction is the true gravity direction, the light emitting unit 130 is turned on for a preset time, and the display unit 120 is illuminated. On the other hand, when it is determined that the mobile device 100 is not stationary, the MPU 150 returns to step S101 and sequentially executes the above-described series of control processes again.

  Also, in the case where either or both of the acquired gravity direction and traveling direction do not satisfy the above conditions in step S105, the MPU 150 returns to step S101 and again performs the above-described series of control. Processes are executed sequentially.

  In the present embodiment described above, based on the acceleration data detected by the three-dimensional acceleration sensor 110 provided in the portable device 100, the gravity direction with respect to the portable device 100 and the traveling direction of the human body are derived, and these gravity values are derived. By determining whether or not the direction and the traveling direction are within the predetermined direction ranges DR1 and DR2, the tilt state of the mobile device 100 (that is, the orientation of the display surface 121 of the display unit 120 visually recognized by the user) is appropriately set. To be judged. Thereby, even when the user wears the mobile device 100 and moves by walking, jogging, or the like, in order for the user to visually recognize the information displayed on the display unit 120, the mobile device 100 is tilted at a predetermined inclination. The display unit 120 can be illuminated by appropriately lighting the light emitting unit 130 without causing a malfunction by appropriately determining the state of operation so as to be in the state. Therefore, according to the present embodiment, it is possible to save power by suppressing the consumption of the built-in battery due to malfunction, and to realize an easy-to-use portable device in which the light is appropriately turned on according to the user's intention. Can do.

  In the present embodiment, since the method of deriving the gravity direction with respect to the mobile device 100 and the traveling direction of the human body based on the acceleration data detected by the three-dimensional acceleration sensor 110 is applied, the three-dimensional acceleration sensor 110 is used. By filtering the output from, high frequency components can be removed. As a result, high-frequency noise components included in the output from the three-dimensional acceleration sensor 110 and components caused by certain repetitive movements such as unintentional hand tremors and blurring of the user are removed, so that the mobile device 100 is shaken. Even in such a case, the light emitting unit 130 can be reliably turned on by appropriately determining the tilt state of the mobile device 100 and the user's operation.

Next, a modified example of the mobile device and the control method thereof shown in the above-described embodiment will be described.
(Modification 1)
FIG. 9 is a schematic diagram illustrating another setting example (modification example 1) of the direction range applied to the determination processing of the tilt state of the mobile device according to the present embodiment. Note that the direction range setting method shown in this modification is an example, and other methods can be applied as long as the direction range in the direction of gravity or the direction of travel is specified.

  In the above-described embodiment, as the direction range setting method applied to the determination process of the tilt state of the mobile device 100, polar coordinate angles α and β representing the gravitational direction and polar coordinate angles θ and φ representing the traveling direction. A method of setting the direction ranges DR1 and DR2 by setting a lower limit value and an upper limit value for each of the above is shown. The present invention is not limited to this, and an individual reference direction is set for each of the gravitational direction and the traveling direction, and an upper limit is set for the total error angle between the acquired gravitational direction and the traveling direction and each reference direction. A method of providing a value may be applied.

  Specifically, as shown in FIG. 9, for example, a reference direction vector Vs represented by polar coordinate angles γ and δ is set in advance for the gravity direction, and an error angle ε of the gravity direction vector Vg with respect to the reference direction vector Vs. Is calculated. Although not shown, the error angle with respect to the individually set reference direction vector is also calculated for the traveling direction (traveling direction vector Vm) by the same method. The MPU 150 is operated so that the user places the portable device 100 in a predetermined tilt state when the total value of the error angles in the weight direction and the traveling direction is equal to or less than a preset upper limit value. Judge.

  Also in the control method according to such a modification, even when the user wears the mobile device 100 and moves by walking, jogging, or the like, as in the above-described embodiment, the user can display the display unit 120. In order to visually recognize the displayed information, it is possible to appropriately determine the state in which the mobile device 100 is operated so as to be in a predetermined tilt state, and to reliably turn on the light emitting unit 130 without causing a malfunction. 120 can be illuminated.

Here, about the structure equivalent to embodiment mentioned above (refer FIG. 2), the same code | symbol is attached | subjected and the description is simplified.

  In the above-described embodiment, as illustrated in FIG. 2, the configuration including only the three-dimensional acceleration sensor 110 as a sensor for detecting the tilt state of the mobile device 100 is illustrated. The present invention is not limited to this, and a configuration including a three-dimensional angular velocity sensor (or a three-axis angular velocity sensor, a three-axis gyro sensor) in addition to the three-dimensional acceleration sensor may be applied.

  Specifically, for example, as shown in FIG. 10, in addition to the configuration shown in the above-described embodiment (see FIG. 2), the mobile device 100 is worn while the user is wearing the mobile device 100, for example, while walking or jogging. Is provided with a three-dimensional angular velocity sensor 190 that detects the inclination and angle applied to the lens and the velocity (angular velocity) of the inclination as angular velocity data. Here, the angular velocity data detected by the three-dimensional angular velocity sensor 190 is output as a component in three orthogonal directions composed of X, Y, and Z axes. These angular velocity data are stored in a predetermined storage area of the memory 160 in association with time information output from the timing circuit 170 together with the acceleration data described above.

  And in the portable device which concerns on this modification, in the derivation | leading-out method of the gravity direction with respect to the portable device 100 shown in embodiment mentioned above and the advancing direction of a user, the angular velocity added to the apparatus main body 101 of the portable device 100 is detected. A method of deriving the gravitational direction by detecting the motion in the rotational direction at all times, tracking the gravitational direction once detected, and calculating the average of acceleration for a certain period as a vector as described above. Thereby, since the detection accuracy of the gravity direction with respect to the portable device 100 can be improved, the influence of vibration, movement, or the like applied to the portable device 100 without the user's intention is greatly suppressed, and the portable device 100 is predetermined. The light emitting unit 130 can be appropriately lit when the tilted state is reached.

  In the present embodiment, it is determined whether the mobile device 100 is in a predetermined tilt state by determining whether the acquired gravity direction and traveling direction are within a preset direction range. Although a technique is shown, the present invention is not limited to this. That is, for the parameters α, β, θ, and φ for defining the direction range to be applied to the determination process, numerical values that define a plurality of types of direction ranges are set in advance for each mode, and the user operates the operation unit 140. Etc. may be used to select an arbitrary mode within the desired direction range, or the user may operate the operation unit 140 or the like to directly input and set a numerical value that defines the direction range. May be.

  In the present embodiment, the case where the parameters α, β, θ, and φ in the polar coordinates are used as a method for representing the gravity direction and the traveling direction acquired by the three-dimensional acceleration sensor 110 has been described. The invention is not limited to this, and other expression methods that indicate directions may be used.

<Second Embodiment>
Next, a second embodiment of the portable device control method according to the present invention will be described.
FIG. 11 is a flowchart illustrating an example of a mobile device control method according to the second embodiment. Here, the description of the processing equivalent to that in the first embodiment described above will be simplified.

  The mobile device according to the second embodiment has a configuration equivalent to that of the first embodiment (see FIG. 2) described above. And the control method of the portable apparatus which concerns on this embodiment is the step shown to 1st Embodiment (refer FIG. 3) mentioned above in step S201-S205 and step S209-S210, as shown in FIG. Processing equivalent to S101 to S105 and steps S108 to S109 is executed.

  That is, when the mobile device 100 is activated and the control process is started, the MPU 150 sequentially acquires acceleration data (sensor data) by the three-dimensional acceleration sensor 110 at a predetermined sampling period (step S201). Next, the MPU 150 derives the direction of gravity by calculating an average of accelerations for a certain period acquired by the three-dimensional acceleration sensor 110 as a vector (step S202), and further, the acceleration acquired by the three-dimensional acceleration sensor 110. Based on the data, the traveling direction of the user is derived (step S203). Next, the MPU 150 determines whether or not the user's direction of travel has been successfully derived in step S203 (step S204). If the traveling direction is not successfully derived, the MPU 150 determines whether the mobile device 100 is stationary (step S209), and when it is determined that the mobile device 100 is stationary. Performs the lighting control process of the light emitting unit 130 using only the acquired direction of gravity (step S210).

  On the other hand, if the derivation of the traveling direction is successful in step S204, the MPU 150 determines whether or not the acquired gravity direction and traveling direction are within a preset direction range (step S205). Then, if either or both of the acquired gravity direction and traveling direction are not within the preset direction range, the MPU 150 calculates the deviation amount from the direction range, The data is stored and accumulated in a predetermined storage area of the memory 160 (step S211), the process returns to step S201, and the above-described series of control processes are sequentially executed again.

  On the other hand, if the acquired gravity direction and traveling direction are within the preset direction range in step S205, the MPU 150 refers to the deviation amount stored and accumulated in the memory 160 for a certain period. Thus, it is determined whether or not the most recent number of deviations calculated before the determination process is greater than or equal to a preset threshold value (step S206). Here, as the deviation amount used in the determination process, a result obtained by tabulating the deviation amount accumulated in the memory 160 for a certain period, for example, by simple cumulative calculation or average value calculation calculation is used. When the most recent deviation amount is equal to or greater than the threshold, the MPU 150 places the mobile device 100 in a predetermined tilt state in order to visually recognize the information displayed on the display unit 120 of the mobile device 100 worn by the user. The light emitting unit 130 is turned on for a preset time to illuminate the display unit 120 (step S207). Then, after the lighting of the light emitting unit 130 is completed for a predetermined time, the MPU 150 determines whether or not to end a series of control processes (step S208). A series of control processes are sequentially executed. On the other hand, if the most recent deviation amount is less than the threshold value in step S206, the MPU 150 returns to step S201 and sequentially executes the series of control processes again.

  Thereby, in this embodiment, when the gravity direction of the portable device 100 and the traveling direction of the user reciprocate within a preset direction range and outside the direction range in a short time, or gradually from outside the direction range. In the case of shifting to the range, for example, it is determined that the user is walking with the mobile device 100 in a bag and the lighting unit 130 is not controlled to be turned on. And the occurrence of malfunctions can be suppressed.

<Third Embodiment>
Next, a third embodiment of the method for controlling a portable device according to the present invention will be described.
FIG. 12 is a flowchart illustrating an example of a mobile device control method according to the third embodiment. Here, description of processing equivalent to that in the first or second embodiment described above is simplified.

  The mobile device according to the third embodiment has a configuration equivalent to that of the above-described first embodiment (see FIG. 2). Here, a direction range (a first direction range, a second direction range, and a third direction range to be described later) applied to the determination process of the tilt state of the portable device is stored in a predetermined storage area of the memory 160 in advance. Has been. And the control method of the portable device which concerns on this embodiment is substantially equivalent to step S101-S108 shown in 1st Embodiment mentioned above (refer FIG. 3) in step S301-S308, as shown in FIG. Processing is executed.

  That is, when the mobile device 100 is activated and the control process is started, the MPU 150 sequentially acquires acceleration data (sensor data) by the three-dimensional acceleration sensor 110 at a predetermined sampling period (step S301). Next, the MPU 150 derives the direction of gravity by calculating an average of accelerations for a certain period obtained by the three-dimensional acceleration sensor 110 as a vector (step S302), and further, the acceleration obtained by the three-dimensional acceleration sensor 110. Based on the data, the traveling direction of the user is derived (step S303).

  Next, in step S303, the MPU 150 determines whether or not the user's direction of travel has been successfully derived (step S304). If the direction of travel has been successfully derived, the acquired gravity direction is set in advance. It is determined whether it is within the first direction range (first direction range) and the acquired traveling direction is within the preset second direction range (second direction range) (step S305). . Here, the first direction range corresponds to, for example, the direction range DR1 shown in the above-described first embodiment (see FIG. 7), and the second direction range corresponds to, for example, the above-described first embodiment (see FIG. 7). This corresponds to the direction range DR2 shown in FIG. Then, when each of the acquired gravitational direction and traveling direction satisfies all the above conditions, the MPU 150 allows the user to visually recognize the information displayed on the display unit 120 of the mobile device 100 worn by the user. It is determined that the mobile device 100 has been operated so as to be in a predetermined tilt state, and the light emitting unit 130 is turned on for a preset time to illuminate the display unit 120 (step S306). Then, after the lighting of the light emitting unit 130 is completed for a predetermined time, the MPU 150 determines whether or not to end a series of control processes (step S307). If not, the MPU 150 returns to step S301 and repeats the above. A series of control processes are sequentially executed.

  On the other hand, if the direction of travel is not successfully derived in step S304, the MPU 150 determines whether the mobile device 100 is stationary (step S308), and determines that the mobile device 100 is stationary. If it is determined, it is determined whether or not the acquired gravity direction is within a preset third direction range (third direction range) (step S309). Here, the third direction range is a direction range set by a method equivalent to the direction range DR1 shown in the first embodiment described above, for example, and is different from the first direction range (for example, The range is narrower than the first direction range. If the acquired direction of gravity falls within the third direction range, the light emitting unit 130 is turned on for a preset time to illuminate the display unit 120 (step S310). Then, after the lighting of the light emitting unit 130 for a predetermined time is completed, the MPU 150 returns to step S301 and sequentially executes the series of control processes again. On the other hand, if it is determined in step S308 that the mobile device 100 is not stationary, and if the acquired gravity direction is not within the third direction range in step S309, the process proceeds to step S301. Returning, the above-described series of control processing is sequentially executed again.

  On the other hand, in step S305, if either or both of the acquired gravity direction and traveling direction do not satisfy the above conditions, the MPU 150 determines whether or not there is a lighting operation of the light emitting unit 130 by the user. Is determined (step S311). That is, in order to visually recognize the information displayed on the display unit 120 of the mobile device 100 worn by the user, the mobile device 100 is operated so as to be in a predetermined tilt state. When the unit 130 is not turned on, it is determined whether or not the user has operated the operation unit 140 or the like to turn on the light emitting unit 130. When there is a lighting operation by the user, based on the polar coordinates α, β, θ, φ representing the acquired gravity direction and the traveling direction, the gravity direction and the traveling direction are the first direction range and the first direction range. The first direction range and the second direction range are corrected so as to be included in the two direction ranges (step S312). The corrected first direction range and second direction range are overwritten and saved in a predetermined storage area of the memory 160. Next, the MPU 150 turns on the light emitting unit 130 for a preset time to illuminate the display unit 120 (step S306), and determines whether or not to end a series of control processes after the predetermined time has elapsed. If not finished (step S307), the process returns to step S301, and the above-described series of control processes are sequentially executed again. On the other hand, if there is no lighting operation by the user in step S311, the MPU 150 determines whether or not to end a series of control processes without lighting the light emitting unit 130 (step S307), and if not, Returns to step S301 and sequentially executes the above-described series of control processes again.

  Thereby, in this embodiment, in addition to the determination process of the inclination state of the mobile device 100 shown in the first embodiment, the user should actually wear the mobile device 100 and turn on the light emitting unit 130. When the user himself performs the lighting operation, the direction range applied to the determination process of the tilt state can be corrected and learned at any time. That is, the corrected direction range is applied in the determination process of the tilt state of the portable device 100 and the lighting control process of the light emitting unit 130 after the next time. Therefore, it is possible to perform the determination process of the tilt state and the lighting control process of the light emitting unit in accordance with the user's specific exercise state and how to move the part (for example, an arm or the like) on which the mobile device is worn. A portable device can be realized.

  In each of the embodiments described above, the case where lighting control of the light emitting unit 130 of the mobile device 100 is described based on the result determined by the determination method of the tilt state, but the present invention is not limited to this. is not. That is, the present invention may determine that the mobile device 100 is in a predetermined tilt state, and drive and control a specific function provided in the mobile device 100. For example, information on the display unit 120 It can be favorably applied to display control, device power on / off control, application software activation, and the like.

  Further, in each of the above-described embodiments, the case where an electronic device having a wristwatch type or wristband type external shape is applied as a portable device has been described, but the present invention is not limited to this. That is, an electronic device that has an outer shape that allows the user to easily view information displayed on the display unit while moving, and that is worn on a specific part of the human body (for example, forearm, elbow, upper arm, back of hand, palm, finger, etc.) Any device or electronic device carried by the user may be used, and for example, the present invention can be favorably applied to a mobile phone, a smartphone, a media player, an activity meter, and the like.
