    摘要: Method for determining the orientation of the trajectory followed by a pedestrian, associated with a trajectory frame, with respect to a reference frame is provided. At least one motion sensor associated with the pedestrian generates data representative of the motion of the sensor housing on the basis of said sensor assembly in the reference frame. A first rotation transformation operator representative of the orientation of the reference frame with respect to the trajectory frame is calculated. The data representative of the motion after transformation by said first operator exhibits at least one characteristic of a set of characteristics which are representative of signals of walking or running motion of a pedestrian and are expressed in the pedestrian frame.

    摘要: A method for filtering the signals arising from a sensor assembly (EC) comprising at least one measurement sensor for measuring a vector physical field which is substantially constant over time and in space in a reference frame, said sensor assembly (EC) being tied in motion to a moving frame, moving in the reference frame, the method comprising the steps consisting in: applying a first transformation (T1) to the measurements of a measurement sensor of the sensor assembly (EC) which are provided in the moving frame, to a pseudo reference frame, with the aid of a first change-of-frame operator (R(t)) by rotation between the moving frame and the pseudo reference frame; and applying a filtering (FILT) to the measurements thus transformed in the pseudo reference frame; and applying a second transformation (T2), the inverse of said first transformation, to the measurements filtered by said filtering (FILT), from the reference frame to the moving frame, with the aid of a second change-of-frame operator (R−1(t)) by rotation between the pseudo reference frame and the moving frame, the inverse of said first operator (R(t)).

    摘要: The invention discloses a device and a method to control an object on a surface using motion sensor measurements and relative and absolute pointing algorithms. Relative pointing is preferred at low speeds and absolute pointing is preferred at high speeds. Transition between the results of the two algorithms has to be smoothed, using a weighted combination of the two results. The weights may be made dependent over time or over speed of the device. Maximum and minimum values of different parameters may have to be set to avoid jumps or changes in direction which may affect the user's experience negatively.The goal is that the user has consistent perceptions what he or she sees on the screen and the movements he or she imparts on the device, while still keeping the position of the object as close as possible to the position calculated by an absolute pointing algorithm.

    摘要: A method for configuring a device for detecting a situation from a set of situations where a physical system comprises the following steps: reception of a learning sequence corresponding to a given situation of the physical system; determination of parameters of a hidden-state Markov statistical model recorded in the detection device and relating to the given situation, on the basis of a prior initialization of these parameters. The prior initialization comprises the following steps: determination of a plurality of probability distributions from the learning sequence; distribution of the probability distributions between the various hidden states of the statistical model in question by global optimization of a function of adaptation of these probability distributions to the various hidden states and to impossible transition constraints; and initialization of the parameters of the statistical model in question using given representative probability distributions for each hidden state of the statistical model in question.

    摘要: A system and method of controlling a cursor (120) in a surface (100) by measurements of attitude of a pointer (110). The measurements can be provided by inertial, optical, magnetic, ultrasound, radiofrequency or video means and appropriate processing means. The method includes a step of computing the displacements of the intersection of a vector tied to the pointer with a projection surface. The projection surface can be predetermined on the basis of the measurements of the attitude and/or of the angular velocity of the pointer. The pointed-at surfaces can be planes, cylinders or spheres. The pointing can be performed in limited fashion or by sliding. The control of the cursor, in absolute mode or in relative mode, can allow the triggering of functions controlled by the orientation of the cursor on the pointed-at surface.
