Abstract
A portable electronic apparatus includes a display, a user position estimating unit and a display movement estimating unit. The user position estimating unit is for estimating the user position with respect to the display. The display movement estimating unit is for estimating the display movement. The apparatus is configured for estimating the user position, here referred to as initial user position, at least at a first moment; and, during at least an interval of time after the first moment, estimating the display movement, and controlling the display content based on the initial user position and the display movement. The invention also relates a method for controlling such an apparatus and to a computer program therefor.
