Abstract
A portable apparatus including an interface configured to input first motion data of a user from a foot-worn first self-contained activity determining unit is disclosed. The portable apparatus also includes a second self-contained activity determining unit configured to determine second motion data of the user. Furthermore, the portable apparatus includes a processing unit configured to determine and store a user-specific dependency between the first motion data and the second motion data, and determine a current speed of the user or a current traveled distance of the user based on current second motion data and the user-specific dependency.
Claims20
A portable apparatus comprising:
- an interface configured to input first motion data representing movement of a user's foot from a foot-worn first self-contained activity determining unit;
- and
- a second self-contained activity determining unit including:
- an accelerometer configured to determine second motion data representing movement of a portion of the user other than the user's foot;
- and
- a processing unit configured to determine a user-specific dependency between the first motion data and the second motion data, the processing unit further configured to determine a current speed of the user or a current traveled distance of the user based on current second motion data and the user-specific dependency.
A method comprising:
- receiving first motion data representing movement of a user's foot from a foot-worn first self-contained activity determining unit;
- determining second motion data representing movement of a portion of the user other than the user's foot by an accelerometer of a second self-contained activity determining unit;
- processing the first motion data and the second motion data to determine a user-specific dependency between the first motion data and the second motion data;
- and
- determining a current speed of the user or a current traveled distance of the user based on current second motion data and the user-specific dependency.
A system comprising:
- a foot-worn first self-contained activity determining unit configured to determine first motion data representing movement of a user's users foot;
- and
- a portable apparatus comprising:
- an interface configured to input the first motion data from the foot-worn first self-contained activity determining unit;
- an accelerometer configured to determine second motion data representing movement of a portion of the user other than the user's foot;
- and
- a processing unit configured to determine a user-specific dependency between the first motion data and the second motion data, the processing unit further configured to determine a current speed of the user or a current traveled distance of the user based on current second motion data and the user-specific dependency.
A portable apparatus comprising:
- means for receiving first motion data representing movement of a user's foot from foot-worn first self-contained activity determining means;
- second self-contained activity determining means for determining second motion data representing movement of a portion of the user other than the user's foot;
- means for determining a user-specific dependency between the first motion data and the second motion data;
- and
- means for determining a current speed of the user or a current traveled distance of the user based on current second motion data and the user-specific dependency.
