Motions, positions or configurations off, for example a human hand can be recognised by transmitting a plurality of transmit signals in respective time frames; receiving a plurality of receive signals; determining a plurality of channel impulse responses using the transmit and receive signals; defining a matrix of impulse responses, with impulse responses for adjacent time frames adjacent each other; and analysing the matrix for patterns (22) corresponding to the motion position or configuration.

La présente invention concerne un procédé selon lequel des mouvements, des positions ou des configurations , par exemple, dune main humaine peuvent être reconnus par la transmission dune pluralité de signaux de transmission dans des trames temporelles respectives ; la réception dune pluralité de signaux de réception ; la détermination dune pluralité de réponses impulsionnelles de canal au moyen des signaux de transmission et de réception ; la définition dune matrice de réponses impulsionnelles, avec des réponses impulsionnelles pour des trames temporelles adjacentes les unes des autres ; et lanalyse de la matrice pour des motifs (22) correspondant au mouvement, à la position ou la configuration.
