Method and system for determining the walking or running speed of a person
First Claim
1. A method of determining the speed of a walking or running person from foot motion comprising the steps of:
- providing at least one pressure sensor between a first foot of the person and a support surface so as to determine the centre of pressure, the pressure sensor being configured for transmitting pressure data to a processing unit,determining a centre of pressure gait line and calculating a centre of pressure speed from the gait line,detecting whether the person is walking or running,obtaining a correlation between the speed of a walking or running person and the centre of pressure speed, anddetermining the speed of the person from the correlation.

Abstract
Method and system for determining the speed of a walking or running person from a foot motion. The method comprises providing (1) a pressure sensor between the foot and the ground, which sensor may be placed on or in an insole of a shoe. The pressure sensor is configured for transmitting pressure data to a communication unit (9). The method further comprises a step of determining a center of pressure gait line (3) and calculating the center of pressure speed (4) from the gait line. In addition, the method comprises the step of detecting whether the person is walking or running (5). Another step (6) is obtaining a correlation between the speed of a person and the center of pressure speed. As a final step (7) of the method the speed of the person is deduced from the correlation. The system comprises a human interface for control and to inform the user.

10. A system for providing the speed of a walking or running person comprising:
-
a sensor for sensing whether a first foot of the person is in contact with a supporting surface, a pressure sensor for determining a centre of pressure of a second foot and for determining a centre of pressure gait line, which sensor is suitable for placing in a shoe, a memory for storing a correlation between a speed of a walking or running person and a centre of pressure speed, a processing unit for calculating the centre of pressure speed from the gait line and, using the stored correlation, calculating a walking or running speed, and a human interface for presenting the walking or running speed. - View Dependent Claims (11, 12, 13)
