A method and a device for inputting information by description of the allowable closed trajectories (ACT). The manipulator unit (1-6) allows description by finger, hand or foot of ACT from a numbered plurality characterized by a common "initial point" (10), closedness, plurality of numbered "characteristic points" (11) lying at intersections of 3, 4, 6, 8, 12 rays outgoing from (10), with 1-4 circles with centres at 10, "trajectory elements" (12) connecting (10) with (11) by segments, (11) with each other by arcs or segments, from (10) to (12) through (11) to (10), when passing (10), (11), sensors (13) are actuated. The inputted information is determined in computing units (9) by an actualised information table on the basis of the number of the described ACT (15), which is determined by the table of the numbers of trajectories (14) from the sequence of the numbers (16) actuated during describing ACT (13), control can be visual and tactile at (1-6), visual on a display (7), audio via a loudspeaker or headphones (8). Preferably, technique of input is trained to an instinctive level, input is performed by the "blind method", continuously and uninterruptedly, by seeing, blind and vision-impaired persons. |
