The head has a data processing part processing characters on a keyboard by a user. A display screen displays the characters, and an off-set apparatus (20) i.e. remote control, held by a hand. The off-set apparatus comprises a detection unit detecting contact or proximity of fingers (30, 30') of the user with a tactile surface (22). A monitoring part monitors the fingers on a CRT screen to display representation (38, 38') i.e. position of a movable area of presence of the finger superposed on a keyboard frame (34). |
