Abstract

A wristwatch includes a storing unit that stores relational data for predetermined user classifications, such as gender and body height, indicating a relationship between a traveling pitch, which is the number of steps taken by a user per predetermined amount of time, and a traveling speed which is a running speed or a walking speed. A correcting unit corrects the stored relational data based on a set of a measured traveling pitch and a measured traveling speed. A speed calculating unit calculates a traveling speed of the user from a measured traveling pitch of the user based on the stored relational data that correspond to a user classification input by the user and that has been corrected.

Claims

1. An electronic apparatus comprising:

a mobile body of a wristwatch, a pedometer, a mobile phone or a smart phone;

an acceleration sensor provided on the mobile body;

a timer provided on the mobile body;

a memory storing relational data for each of predetermined user classifications, the relational data indicating a relationship between a traveling pitch, which is the number of steps taken per predetermined amount of time, and a traveling speed which is a running speed or a walking speed; and

one or more processors, in communication with the acceleration sensor, the timer and the memory, configured to;

acquire an actual set of traveling pitch and traveling speed related to a user based on an actual action of the user;

correct the relational data, which is stored in the memory, based on the actual set of traveling pitch and traveling speed;

measure a traveling pitch of the user based on acceleration parameters from the acceleration sensor; and

calculate a traveling speed of the user based on the measured traveling pitch of the user and on the relational data that correspond to a user classification input by the user and that has been corrected, without using a fixed step length value of the user.

2. The electronic apparatus according to claim 1,

wherein the one or more processors are configured to receive an input of a body height of the user or information relating to the body height of the user,

the memory stores the relational data indicating a relationship between a body height or information relating to the body height, a traveling pitch which is the number of steps taken per predetermined amount of time, and a traveling speed which is a running speed or a walking speed, and

the one or more processors are configured to calculate the traveling speed of the user based on the body height or the information relating to the body height and on the measured traveling pitch of the user based on the relational data stored in the memory.

3. The electronic apparatus according to claim 1, wherein the one or more processors are configured to:

acquire a plurality of sets of a measured traveling pitch and a traveling speed measured during measurement of the traveling pitch; and

generate the relational data indicating the relationship between the traveling pitch and the traveling speed based on the acquired plurality of sets of the traveling pitch and the traveling speed.

4. The electronic apparatus according to claim 1,

wherein the one or more processors are configured to receive an input of a set of a traveling pitch and a running quickness or a walking quickness.

5. The electronic apparatus according to claim 1,

wherein the one or more processors are configured to calculate a traveling distance, which is a running distance or a walking distance of the user, based on the calculated traveling speed.

6. The electronic apparatus according to claim 1,

wherein the one or more processors are configured to calculate a traveling pace, which is a walking pace or a running pace of the user, based on the calculated traveling speed.

7. The electronic apparatus according to claim 1,

wherein the memory stores table data indicating a relationship between the traveling pitch and the traveling speed.

8. The electronic apparatus according to claim 1,

wherein the one or more processors are configured to calculate a traveling pace, which is a running pace or a walking pace of the user, instead of the traveling speed of the user.

9. The electronic apparatus according to claim 1, wherein the user classifications include gender of the user.

10. The electronic apparatus according to claim 1, wherein the user classifications include body height or information relating to body height of the user.

11. A non-transitory computer readable medium storing a program causing a computer to execute:

a step of acquiring an actual set of traveling pitch and a traveling speed measured during measurement of the traveling pitch based on an actual action of a user;

a step of correcting relational data indicating a relationship between a traveling pitch, which is the number of steps taken per predetermined amount of time, and a traveling speed, which is a running speed or a walking speed, based on the acquired actual set of the traveling pitch and the traveling speed;

a step of measuring a traveling pitch of the user based on acceleration parameters from an acceleration sensor; and

a step of calculating a traveling speed of the user based on the measured traveling pitch of the user and on relational data that correspond to a user classification input by the user and that has been corrected, without using a fixed step length value of the user.
