Title: SYSTEM AND METHOD FOR OBSERVING A PERSON'S WALKING ACTIVITY
Abstract:
The invention relates to a system for observing a person's walking activity, including a device (DISP) which, for one footstep, can output: a first difference between the angular speeds of the tibia, corresponding to the difference between the moment at which the heel of the foot is placed and the moment at which the foot is laid flat; a second difference between the angular speeds of the tibia, corresponding to the difference between the moment at which the heel is placed and the moment at which the last toe of the foot is lifted; and an angular speed of the tibia, corresponding to the moment at which the foot is laid flat. The system includes a means (AN) for analyzing the signals generated by the device and capable of determining a gait type for the user as a function of time, using a hidden Markov model having N states that respectively correspond to N gait types.
