摘要：The invention relates to an electronic device (10), which includes a displaycomponent (11) , in which at least one controllable element (13) is arranged to bevisualized in its entirety, the control of which element (13) is arranged to be based ondetermining a change (M) relating to the attitude or position of the device (10); andcamera means (14, 15) arranged to form image frames (IMAGEl, IMAGE2) , and in which, inorder to control the functions of the device (10), such as, for example, to control theelement, the change is arranged to be determined, using optical data-flow algorithms(17.2), from the image frames formed by the camera means, which image frames arearranged to be compared to each other in a set manner, and on the basis of whichcomparison the said change is arranged to be determined. The image frames arearranged to be segmented in a selected manner, from which at least one movementvector (SR, SL, SUp, SDown) determining the said change is arranged to be determined

from at least some of the segments ( SEGMENT 1, SEGMENT2).
