1. A portable communication device (4) for transmitting information in electrical form between a user and a certain data communication system, characterized in that it comprises:

  • an outer covering (10, 11) including upper and lower halves which can be moved between a folded condition and an unfolded condition by actions of the user, said lower half (11) containing the heaviest structural parts of said portable communication device including a microphone (5), a speaker (6), and sound channelling means for directing sound to the microphone and from the speaker, said lower half (11) being substantially heavier than said upper half (10); and

    in order to realize the interaction between said communication device (4) and the user, as separate items;

    a first user interface in said lower half (11) with first input means (5, 7, 8) and first indicator means (9); and

    a second user interface in said upper half (10) with second input means (13, 14, 15, 16, 17) and second indicator means (12);

    of which said first user interface comprises parts (5, 6, 7, 8, 9), which are located substantially on the outer surface of said outer covering (10, 11), so that they can be used when said upper and lower halves are in the folded condition, without unfolding said outer cover, and of which said second user interface comprises parts (12, 13, 14, 15, 16, 17), which are located substantially inside said outer covering (10, 11), so that they can be used when said upper and lower halves are in the unfolded condition outer covering is unfolded, said portable communication device being balanced for firm placement of said lower half (11) of said outer covering on a substantially flat level surface, with said upper half (12) of said outer covering positioned such that the included angle between said lower half and said higher half is less than 180°
