摘要：
According to an aspect, there is provided a method of determining a position and/or orientation of a hand-held device with respect to a subject. The hand-held device is for use on a body of the subject. The method comprises receiving (101) images from an imaging unit arranged in or on the hand-held device； receiving (103) a displacement signal from a displacement sensor that is arranged in or on the hand-held device to measure displacement of the hand-held device along the body when the hand-held device is in contact with the body； processing (105) the received images to determine whether a body part of the subject can be identified in the received images； determining (107) whether the hand-held device is in contact with the body； determining (109) a mode of operation to use to determine a position and/or orientation of the hand-held device based on whether a body part can be identified and whether the hand-held device is in contact with the body； wherein the mode of operation to use is determined as (i) a first mode when a body part can be identified, (ii) a second mode when a body part cannot be identified and the hand-held device is not in contact with the body, and (iii) a third mode when the hand-held device is in contact with the body； and determining (111) the position and/or orientation of the hand-held device with respect to the body of the subject using the received images and/or received displacement signal according to the determined mode of operation.Selon un aspect, l'invention concerne un procédé de détermination d'une position et/ou d'une orientation d'un dispositif portatif par rapport à un sujet. Le dispositif portatif est destiné à être utilisé sur un corps du sujet. Le procédé consiste à recevoir (101) des images provenant d'une unité d'imagerie agencée dans ou sur le dispositif portatif ； à recevoir (103) un signal de déplacement provenant d'un capteur de déplacement qui est disposé dans ou sur le dispositif portatif pour mesurer le déplacement
