Abstract
A portable computer device has data acceptance logic (24,40) that determines whether input data items have time and location information. If not, data items are stored together with time and location information taken from clock (30) and location determining circuitry (28), here a Global Positioning Service (GPS) system. A screen (6) is arranged to display data items in a time mode or a space mode. In the time mode, those data items with time information in a time interval are displayed on a time line. In a space mode, data items with time information in a display area are displayed, for example on a map of the display area. The display can be toggled between the time and space modes.
