1. A method for recognising a selection from a set of at least two alternatives, the method comprising:

  • determining the positions corresponding to each alternative in the space surrounding a user on the basis of their distance and direction with respect to the user so that the locations of the positions remain substantially the same with respect to the user irrespective of the location of the user;

    allowing the user to carry out a first movement for moving a member of the body to a position corresponding to an alternative the user desires;

    recognising a second movement carried out by the user in the position corresponding to the alternative the user desires;

    in response to the second movement, recognising the selection the user desires as completed; and

    providing the recognised selection as an output.
