摘要
The invention relates in particular to the detection of interactions with a software application according to a movement of an object situated in the field of an image sensor. After having received a first and a second image and having identified a first region of interest in the first image, a second region of interest, corresponding to the first region of interest, is identified in the second image. The first and second regions of interest are compared and a mask of interest characterizing a variation of at least one feature of corresponding points in the first and second regions of interest is determined. A movement of the object is then determined from said mask of interest. The movement is analyzed and, in response, a predetermined action is triggered or not triggered.
