An operation method of a user interface of a handheld device, like a palm-size or pocket-size PC, mobile telephone, communicator or equivalent, in which method data on a display of the device is changed for finding or selecting desired data, is characterized in that data (5a - 5e) on the display (2') of the device is changed responsive to certain movements (F) of the device in a three-dimensional space of use thereof, and said movements of the device and the corresponding changes of the data on the display are defined so that a movement and a corresponding change of data on the display have a cause-consequence relationship which is analogous to cause-consequence relationships of the three-dimensional space of perception and action of a user (1). |
