(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In this embodiment, an example of a wristwatch will be described as an example of an electronic device. FIG. 1 is a block diagram illustrating a configuration of a wristwatch 100 according to the present embodiment. The wristwatch 100 is an electronic timepiece that measures a user's travel pitch and calculates and displays the user's travel speed and travel pace from the measured travel pitch. The traveling pitch is the number of steps per predetermined time (for example, 1 minute). The traveling speed is a walking speed or a traveling speed. The travel pace is the travel time for a predetermined distance.

  In the illustrated example, the wristwatch 100 includes a processing unit 101 (calculation unit, correction unit), a display unit 102, a storage unit 103, a power source 104, a travel detection unit 105, an acceleration sensor 106, and an input switch 107. The frequency divider 108 and the crystal oscillator 109 are provided.

  The processing unit 101 is a central processing unit that controls each unit included in the wristwatch 100. For example, the processing unit 101 calculates the user's travel speed from the user's travel pitch measured by the travel detection unit 105 based on relational data indicating the relationship between the travel pitch and the travel speed. Further, the processing unit 101 corrects the relational data stored in the storage unit 103 based on the set of the actual traveling pitch and the actual speed measured at the time of the pitch measurement. Further, the processing unit 101 calculates the user's travel distance based on the calculated travel speed. The travel distance is a walked distance or a traveled distance. Further, the processing unit 101 calculates a travel pace based on the calculated travel speed. In addition, the processing unit 101 causes the display unit 102 to display information related to traveling. The information related to travel is, for example, travel time, number of steps, travel pitch, travel speed, travel distance, travel pace, or the like. The running time is the time spent walking or running.

  The display unit 102 is, for example, a liquid crystal display, and displays time, information related to traveling, and the like. The storage unit 103 includes a ROM (Read Only Memory) and a RAM (Random Access Memory), and stores data used by each unit included in the wristwatch 100. The power source 104 supplies power to each unit included in the wristwatch 100.

  The acceleration sensor 106 detects acceleration. The travel detection unit 105 (step count measurement unit) measures the travel pitch of the user based on the acceleration detected by the acceleration sensor 106. For example, the travel detection unit 105 measures the travel pitch of the user based on acceleration (information related to landing) based on body movement related to travel or walking. Specifically, the traveling detection unit 105 detects the vibration of the body during traveling or walking from the acceleration detected by the acceleration sensor 106 and measures the number of steps. Then, the traveling detection unit 105 measures the traveling pitch based on the measured traveling time and the measured number of steps.

  The input switch 107 is configured by a switch that can be operated from the outside, and is an input unit that receives an input. The crystal oscillation unit 109 outputs a signal having a predetermined frequency. The frequency divider 108 divides the output signal of the crystal oscillating unit 109 by a predetermined frequency dividing ratio and outputs a reference clock signal for the processing unit 101 and a clock signal for timing. The processing unit 101, the frequency dividing unit 108, and the crystal oscillation unit 109 are time measuring units (lap time measuring units) that measure time. The timekeeping unit realizes a stopwatch function for measuring the travel time of the user and a clock function for measuring the current time.

  FIG. 2 is plot data showing the relationship between the running pitch and the running speed. It can be seen from the plot data 201 of the running pitch and the running speed shown in this figure that there is a correlation between the running pitch and the running speed. For example, in general, when a person is walking or running, the running pitch is high when running fast (or walking), and the running pitch is low when running slowly (or walking). Tend. For this reason, the traveling speed can be derived from the traveling pitch by preparing a predetermined relational expression in advance. Therefore, the storage unit 103 according to the present embodiment stores in advance a relational expression indicating the relationship between the travel pitch and the travel speed.

  Next, a relational expression indicating the relationship between the travel pitch and the travel speed stored in the storage unit 103 will be described. As shown in FIG. 2, the traveling pitch and the traveling speed are related to each other and can be expressed by a linear expression “traveling speed V = (slope) × traveling pitch P− (offset)”. In this embodiment, a relational expression “V = a × P−b” having an inclination of a and an offset of b is used. The travel pitch P is calculated based on the number of steps and travel time when the user actually travels the predetermined distance d. Further, the inclination a is a predetermined value. Further, the offset b used for correcting the relational expression is determined based on a set of the user's actual traveling pitch P and actual traveling speed V.

  The set of the user's actual travel pitch P and the actual travel speed V can be measured by the user actually traveling the predetermined distance d. The predetermined distance d is set in the wristwatch 100 in advance. Note that the predetermined distance d set in the wristwatch 100 can be changed by the user from the input switch 107 or the like. The processing unit 101 measures the time that the user has traveled the predetermined distance d. Then, the processing unit 101 calculates the actual traveling speed by dividing the traveling distance by the predetermined distance d. The travel detection unit 105 measures the number of steps when the user travels the predetermined distance d, and calculates the actual travel pitch by dividing the measured number of steps by the travel time.

  Next, a method for correcting the relational expression will be described. The relational expression can be corrected by changing the value of the offset b. In the present embodiment, the processing unit 101 corrects the relational expression based on the set of the user's actual traveling pitch and actual traveling speed.

  FIG. 3 is a graph for explaining a relational expression correction method in the present embodiment. The horizontal axis of the graph is the travel pitch, and the vertical axis is the travel speed. A dotted line 301 indicates a relational expression (relational expression before correction) in which the offset b is zero. A solid line 302 represents the corrected relational expression. A point 303 is a point specified by a set of an actual travel pitch P and an actual travel speed V. The processing unit 101 operating as a correction unit changes the offset b of the relational expression so as to pass through a point 303 specified by a set of an actual traveling pitch and an actual traveling speed. Thereby, the relational expression can be corrected. At this time, the processing unit 101 does not change the slope a of the relational expression.

  Next, the timing for correcting the relational expression will be described. FIG. 4 is a schematic diagram illustrating the timing for acquiring the lap time in the present embodiment. In the example shown in the figure, the user acquires the lap time every time he travels 5 km after starting the travel. In the present embodiment, the wristwatch 100 corrects the relational expression using the first acquired lap time and the number of steps. That is, the wristwatch 100 corrects the relational expression based on the value acquired at the first lap (predetermined lap).

  The wristwatch 100 calculates a travel distance and a travel speed using the corrected relational expression for the second and subsequent laps. Thereby, since the relational expression corrected based on the actually traveled value can be used, the travel distance and travel speed of the user can be calculated more accurately.

  Next, the operation procedure of the wristwatch 100 will be described. FIG. 5 is a flowchart showing an operation procedure when the wristwatch 100 according to the present embodiment performs a lap time acquisition process.

(Step S101) The processing unit 101 starts measurement of a stopwatch. Thereafter, the process proceeds to step S102.
(Step S102) The processing unit 101 determines whether or not an input of a lap time acquisition instruction has been received. If the processing unit 101 determines that an input of a lap time acquisition instruction has been received, the process proceeds to step S103. Otherwise, the process proceeds to step S106.

(Step S103) The processing unit 101 acquires a lap time. Thereafter, the process proceeds to step S104.
(Step S104) The processing unit 101 determines whether or not the lap time acquired in the process of step S103 is the first lap time. When the processing unit 101 determines that the lap time is the first lap, the process proceeds to step S105. Otherwise, the process proceeds to step S106.

(Step S105) The processing unit 101 corrects the relational expression stored in the storage unit 103 using the pitch P and the traveling speed V of the first lap. Thereafter, the process proceeds to step S106.
(Step S106) The processing unit 101 determines whether or not an input of a lap time measurement end instruction has been received. If the processing unit 101 determines that an input of a lap time measurement end instruction has been received, the process ends, otherwise the process returns to step S102.

  For example, when the date and time elapses, the relationship between the pitch and the running speed changes due to improvement in running ability or condition. Therefore, according to the present embodiment, the wristwatch 100 corrects the relational expression indicating the relationship between the traveling pitch and the traveling speed using the first acquired lap time and the number of steps out of the lap time and the number of steps during the same traveling. To do. Thereby, even when calculating a user's travel distance and travel pace using a relational expression, it can calculate more correctly.

  Further, according to the present embodiment, the wristwatch 100 corrects the relational expression indicating the relationship between the travel pitch and the travel speed using the first acquired lap time and the number of steps. Therefore, the wristwatch 100 can correct the relational expression indicating the relation between the running pitch and the running speed without inputting the number of steps or the like by using means such as button operation or communication in advance.

  In the above-described example, the wristwatch 100 corrects the relational expression indicating the relation between the running pitch and the running speed using the lap time and the number of steps acquired in the first lap, but the present invention is not limited to this. For example, using the lap time and the number of steps acquired in laps other than the first lap such as the second lap and the third lap, the relational expression indicating the relationship between the running pitch and the running speed stored in the storage unit 103 is corrected. May be.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. The wristwatch 100 in the present embodiment has the same configuration as the wristwatch 100 in the first embodiment. The difference between the present embodiment and the first embodiment is the timing for correcting the relational expression.

  Next, the timing for correcting the relational expression in the present embodiment will be described. In the present embodiment, the wristwatch 100 corrects the relational expression every time the lap time is acquired. That is, the wristwatch 100 corrects the relational data stored in the storage unit 103 based on the last calculated travel pitch and travel speed (travel pitch and travel speed of the previous lap). Thereby, for example, when running a marathon event or a track, it is possible to obtain more effects in a usage situation in which a lap is taken each time at a predetermined distance.

  Next, the operation procedure of the wristwatch 100 will be described. FIG. 6 is a flowchart showing an operation procedure when the wristwatch 100 according to the present embodiment performs a lap time acquisition process.

(Step S201) The processing unit 101 starts measuring a stopwatch. Thereafter, the process proceeds to step S202.
(Step S202) The processing unit 101 determines whether or not an input of a lap time acquisition instruction has been received. If the processing unit 101 determines that an input of a lap time acquisition instruction has been received, the process proceeds to step S203. Otherwise, the process returns to step S202.

(Step S203) The processing unit 101 acquires a lap time. Thereafter, the process proceeds to step S204.
(Step S <b> 204) The processing unit 101 corrects the relational expression using the pitch P and the traveling speed V of the last acquired lap (immediate lap). Thereafter, the process proceeds to step S205.
(Step S205) The processing unit 101 determines whether or not an input of a lap time measurement end instruction has been received. If the processing unit 101 determines that an input of a lap time measurement end instruction has been received, the process ends. Otherwise, the process returns to step S202.

  For example, as the running time becomes longer, the relationship between the pitch and the stride changes due to fatigue and the like. Therefore, according to the present embodiment, the wristwatch 100 corrects the relational expression indicating the relationship between the traveling pitch and the traveling speed using the lap time and the number of steps acquired immediately before the lap time and the number of steps during the same traveling. To do. Thereby, even when calculating a user's travel distance and travel pace using a relational expression, it can calculate more correctly.
