Graphical Input Techniques.
Abstract
A graphic work station has been created where three aspects of man-machine interaction may be tested: (1) interaction with a flat display; (2) co-planar input and output; and (3) the ability to 'see through your hand' to a display below. All three are created by a suitable arrangement of mirrors to direct a projected television image to a back-projection screen which is in turn optically superimposed onto a data tablet surface via a semi-transparent mirror. Uses and benefits of the device are demonstrated by means of a set of games which simulate a situation where a user must interact with dynamically changing data and imagery, and annotation programs where rapid data entry from hard copy is required.
