Abstract
There is provided a method of processing measurements of acceleration to identify steps by a user, the method comprising obtaining measurements of acceleration from a device worn or carried by a user; analysing the measurements of acceleration to determine a value for a threshold that is to be used to identify steps by the user in measurements of acceleration; and using the determined value for the threshold to identify steps by the user in measurements of acceleration.
Claims15
A method of processing measurements of acceleration to identify steps by
- a user, the method comprising:
- obtaining measurements of acceleration from a device worn or carried by a user;
- analysing the measurements of acceleration to determine a value for a threshold that is to be used to identify steps by the user in measurements of acceleration;
- and
- using the determined value for the threshold to identify steps by the user in measurements of acceleration;
- wherein, for a walking part comprising a series of steps identified in the measurements of acceleration, the method further comprises:
- testing the identified steps for regularity;
- adding a step by the user to the series of steps if it is determined from the result of the step of testing that a step by the user has been missed;
- and
- removing a step by the user from the series of steps if it is determined from the result of the step of testing that there is a duplicated step by the user.
An apparatus for processing measurements of acceleration to identify steps by a user, the apparatus comprising:
- a processing unit configured to
- obtain measurements of acceleration from a device worn or carried by a user;
- analyse the measurements of acceleration to determine a value for a threshold that is to be used to identify steps by the user in measurements of acceleration;
- use the determined value for the threshold to identify steps by the user in measurements of acceleration;
- test the identified steps for regularity;
- add a step by the user to the series of steps if it is determined from the result of the testing that a step by the user has been missed;
- and
- remove a step by the user from the series of steps if it is determined from the result of the testing that there is a duplicated step by the user.
