Arrangement, method and computer program for determining physical activity level of human being
First Claim
1. An arrangement for determining the physical activity level of a human being, the arrangement comprising:
- a movement sensor capable of being attached to an upper limb of the human being for measuring upper limb movements; and
a processing unit connected to the movement sensor for filtering the upper limb movements during a determination period such that the upper limb movements measured during a predetermined threshold period following each accepted upper limb movement are rejected from the accepted upper limb movements, for forming the number of filtered upper limb movements during the determination period from the number of accepted upper limb movements during the determination period, for determining the physical activity level on the basis of the number of filtered upper limb movements during the determination period, and for recognizing filtered upper limb movements as a rhythmic activity if a number of intervals between subsequent filtered movements according to a predetermined number threshold value are equal with the accuracy of a predetermined variation threshold value and using the recognized rhythmic action in determining the physical activity level, wherein the processing unit is further configured to filter the filtered upper limb movements following one another more frequently than an extended threshold period if the processing unit did not recognize the filtered upper limb movements as a rhythmic activity and to use the doubly filtered upper limb movements in forming the number of movements and in determining the physical activity level.

Abstract
An arrangement, method and computer program for determining the physical activity level of a human being. The arrangement comprises a movement sensor to be attached to an upper limb of the human being for measuring upper limb movements, a processing unit connected to the movement sensor for filtering upper limb movements following one another more frequently than a predetermined threshold period from upper limb movements during a determination period, for forming the number of upper limb movements during the determination period from the filtered upper limb movements during the determination period, and for determining the physical activity level on the basis of the number of upper limb movements during the determination period formed from the filtered upper limb movements during the determination period.

12. A method of determining the physical activity level of a human being, the method comprising:
-
measuring upper limb movements of the human being; filtering, using a processing device, the upper limb movements during a determination period such that the upper limb movements measured during a predetermined threshold period following each accepted upper limb movement are rejected from the accepted upper limb movements; forming, using the processing device, the number of filtered upper limb movements during the determination period from the number of accepted upper limb movements during the determination period; determining, using the processing device, the physical activity level on the basis of the number of filtered upper limb movements during the determination period; providing user access to the physical activity level; recognizing filtered upper limb movements as a rhythmic activity if a number of intervals between subsequent filtered movements according to a predetermined number threshold value are equal with the accuracy of a predetermined variation threshold value; using the rhythmic activity in determining the physical activity level; filtering the filtered upper limb movements following one another more frequently than an extended threshold period if the filtered upper limb movements were not recognized as a rhythmic activity; and using the doubly filtered upper limb movements in forming the number of movements and in determining the physical activity level. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. An arrangement for determining the physical activity level of a human being, the arrangement comprising:
-
movement measuring means for measuring upper limb movements, the movement measuring means for measuring upper limb movements capable of being attached to an upper limb of the human being; and processing means for filtering the upper limb movements during a determination period such that the upper limb movements measured during a predetermined threshold period following each accepted upper limb movement are rejected from the accepted upper limb movements, for forming the number of filtered upper limb movements during the determination period from the number of accepted upper limb movements, for determining the physical activity level on the basis of the number of filtered upper limb movements during the determination period, and for recognizing filtered upper limb movements as a rhythmic activity if a number of intervals between subsequent filtered movements according to a predetermined number threshold value are equal with the accuracy of a predetermined variation threshold value and using the recognized rhythmic activity in determining the physical activity level, wherein the processing means is further configured to filter the filtered upper limb movements following one another more frequently than an extended threshold period if the processing means did not recognize the filtered upper limb movements as a rhythmic activity and to use the doubly filtered upper limb movements in forming the number of movements and in determining the physical activity level.

24. A non-transitory computer-readable distribution medium comprising computer program instructions stored thereon configured to cause a data processing device to determine the physical activity level of a human being by:
-
receiving measured upper limb movements of the human being; filtering the upper limb movements during a determination period such that the upper limb movements measured during a predetermined threshold period following each accepted upper limb movement are rejected from the accepted upper limb movements; forming the number of filtered upper limb movements during the determination period from the number of accepted upper limb movements during the determination period; determining the physical activity level on the basis of the number of filtered upper limb movements during the determination period; recognizing filtered upper limb movements as a rhythmic activity if a number of intervals between subsequent filtered movements according to a predetermined number threshold value are equal with the accuracy of a predetermined variation threshold value; using the rhythmic activity in determining the physical activity level; filtering the filtered upper limb movements following one another more frequently than an extended threshold period if the filtered upper limb movements were not recognized as a rhythmic activity; and using the doubly filtered upper limb movements in forming the number of movements and in determining the physical activity level. - View Dependent Claims (25)
