Abstract

There is provided an information processing apparatus including a speed calculating section configured to calculates a traveling speed of a user based on a signal received from a positioning signal transmitter, a walking tempo acquiring section configured to acquire a walking tempo of the user, and an evaluating section configured to evaluate, based on the walking tempo and the traveling speed, reliability of information calculated by using the signal received from the positioning signal transmitter.

Claims

1. An information processing apparatus comprising:

a speed calculating section configured to calculates a traveling speed of a user based on a signal received from a positioning signal transmitter;

a walking tempo acquiring section configured to acquire a walking tempo of the user; and

an evaluating section configured to evaluate, based on the walking tempo and the traveling speed, reliability of information calculated by using the signal received from the positioning signal transmitter.

2. The information processing apparatus according to claim 1, wherein

the evaluating section evaluates the reliability based on a correlation coefficient between the walking tempo and the traveling speed if dispersion of the walking tempo is equal to or more than a predetermined threshold value, and evaluates the reliability based on frequency distribution of the traveling speed if the dispersion of the walking tempo is less than the predetermined threshold value.

3. The information processing apparatus according to claim 1, wherein

the evaluating section evaluates the reliability of the traveling speed calculated based on the signal received from the positioning signal transmitter, and

the information processing apparatus further comprises a table generating section for generating an association table between the traveling speed and the walking tempo by using the traveling speed that is determined to be equal to or more than a predetermined level based on a result of the evaluation.

4. The information processing apparatus according to claim 3, further comprising

a position calculating section configured to calculate a position of the user by using the association table generated by the table generating section.

5. The information processing apparatus according to claim 4, further comprising

a display controlling section configured to display in a superimposed manner the position calculated by the position calculating section on a map.

6. The information processing apparatus according to claim 1, wherein

the information calculated by using the signal received from the positioning transmitter is positional information.

7. The information processing apparatus according to claim 1, wherein

the information calculated by using the signal received from the positioning transmitter is orientation information.

8. An information processing apparatus comprising:

a walking tempo acquiring section configured to acquire a walking tempo of a user;

a traveling speed acquiring section configured to acquire a traveling speed extracted, based on the walking tempo acquired by the walking tempo acquiring section, from an association table between the traveling speed and the walking tempo generated by using the traveling speed whose reliability is evaluated based on a correlation between the traveling speed calculated based on a signal received from a positioning signal transmitter and the walking tempo; and

a position calculating section configured to calculate the position of the user based on the traveling speed.

9. The information processing apparatus according to claim 8, further comprising

a display controlling section configured to display in a superimposed manner the position calculated by the position calculating section on a map.

10. An information processing method comprising:

calculating a traveling speed of a user based on a signal received from a positioning signal transmitter;

acquiring a walking tempo of the user; and

evaluating, based on the walking tempo and the traveling speed, reliability of information calculated by using the signal received from the positioning signal transmitter.

11. A program allowing a computer to function as an information processing apparatus, the information processing apparatus including:

a speed calculating section configured to calculates a traveling speed of a user based on a signal received from a positioning signal transmitter;

a walking tempo acquiring section configured to acquire a walking tempo of the user; and

an evaluating section configured to evaluate, based on the walking tempo and the traveling speed, reliability of information calculated by using the signal received from the positioning signal transmitter.
