COMPUTER INPUT UNIT SUITABLE FOR USE BY RIGHT-HANDED PEOPLE AND LEFT-HANDED PEOPLE

摘要

An input unit (2) for a computer (1) is described, which is adapted to be used in at least two different modes, in particular one for right-handed people and one for left-handed people. The input unit (2) comprises a plurality of keys (21) and a control unit (400) which detects when the keys (21) are pressed. Each key (21) is associated with a read code which is transmitted to the computer by the control unit (400) when the input unit (2) is operating in a first one of said two modes. The keys (21) are arranged according to a centrally symmetric configuration. When the input unit (2) is operating in the second one of said two modes, as a first key is pressed the control unit (400) will transmit the read code of a second key; the latter is the key which is symmetric to the key actually pressed with respect to the centre of symmetry of the plurality of keys.
