Abstract

The idea of the present invention is to browse information on a display device of a hand-held device naturally and logically. Characteristic of the invention is that information is browsed on the display device essentially in a mirror-like way. In other words, the portion of the virtual data object displayed on the display device is moved in the same direction as the hand-held device is tilted. In other words, the movements of the portion of the virtual data object displayed on the display device depends on the orientation of the hand-held device. An important feature of the invention is also that a certain orientation of the hand-held device always displays the same portion of the virtual data object on the display device. The browsing method described above is extremely logical, and the movements and responses to the movements are natural.
