METHOD AND APPARATUS FOR IDENTIFYING TRANSITIONS BETWEEN SITTING AND STANDING POSTURES
First Claim
1. A method for identifying transitions between a standing posture and a sitting posture by a user, the method comprising:
- obtaining measurements of the acceleration experienced by the user during movement;
obtaining a signal indicating the height of a part of the user during movement;
processing the measurements of the acceleration to identify candidate movements corresponding to transitions between a standing posture and a sitting posture; and
determining an identified candidate movement as a transition from a sitting posture to a standing posture where the identified candidate movement coincides with an increase in height in the signal and an identified candidate movement as a transition from a standing posture to a sitting posture where the identified candidate movement coincides with a decrease in height in the signal.

12. A computer program product, comprising computer program code that, when executed on a computer or processor, causes the computer or processor to identify transitions between a standing posture and a sitting posture in measurements of the movement of a user by:
-
obtaining measurements of the acceleration experienced by the user during movement; obtaining a signal indicating the height of a part of the user during movement; processing the measurements of the acceleration to identify candidate movements corresponding to transitions between a standing posture and a sitting posture; and determining an identified candidate movement as a transition from a sitting posture to a standing posture where the identified candidate movement coincides with an increase in height in the signal and an identified candidate movement as a transition from a standing posture to a sitting posture where the identified candidate movement coincides with a decrease in height in the signal.

13. An apparatus for identifying transitions between a standing posture and a sitting posture in measurements of the movement of a user, the apparatus comprising:
-
a processing unit configured to; process measurements of an acceleration experienced by the user to identify candidate movements corresponding to transitions between a standing posture and a sitting posture; and determine an identified candidate movement as a transition from a sitting posture to a standing posture where the identified candidate movement coincides with an increase in height in a signal indicating the height of a part of the user during movement, and determine an identified candidate movement as a transition from a standing posture to a sitting posture where the identified candidate movement coincides with a decrease in height in the signal indicating the height of the part of the user. - View Dependent Claims (14, 15)
