A method estimating orientation of a path followed by a carrier of a movement sensor includes: determining an orientation of the movement sensor with respect to the path; estimating an orientation of the movement sensor with respect to a fixed reference; estimating an orientation of the path with respect to the fixed reference by the determined orientation of the movement sensor and the estimated orientation of the movement sensor; detecting start and end of a phase of disorientation of the movement sensor with respect to the path; updating, after the detected end of the disorientation phase, determined orientation of the movement sensor with respect to the path by orientation of the path with respect to the fixed reference as estimated at the detected start of the disorientation phase and orientation of the movement sensor with respect to the fixed reference as estimated after the detected end of the disorientation phase.


A method for the continuous recognition of gestures of a user of a handheld mobile terminal fitted with a motion sensor assembly, includes the steps of, for at least one motion sensor measuring signal of the motion sensor assembly, over a time window: The candidate gesture detection step (

The invention discloses a 3D pointing device and a method to control an object on a surface and improve the user experience when the user moves the object beyond the limits of the surface where the object can no longer be visualized. The user experience is enhanced by defining the behaviour of a cursor in a margin around the screen.

A system for observing a walking activity of a person comprises a device (DISP) adapted for delivering at output, for a footstep of the person, a first difference of angular speeds of the corresponding tibia between the instant at which the heel of the foot is planted and the instant at which the foot is laid flat, a second difference of angular speeds of the corresponding tibia between the instant at which the heel of the foot is planted and the instant at which the last toe of the foot is lifted, and an angular speed of the corresponding tibia at the instant at which the foot is laid flat. The system comprises analysis means (AN) for analyzing the signals delivered by the device and adapted for determining a type of walking of the user as a function of time by using a hidden Markov model with N states corresponding respectively to N types of walking


A method of location of a device includes the provision of a map containing at least one zone with favored direction of displacement associated with a favored direction of displacement. The method includes an operation of detecting the presence of a particle inside the zone. If the particle is detected as being present inside the zone, an operation of increasing a weight of the particle if the angular deviation between the direction of displacement of the particle from a position P
