ABSTRACT:
An audio frequency based data capture tablet (26) includes a working surface (210) upon which a data collection document having marked responses is placed. A movable cursor (212, 222), which is mechanically disposed above the working surface (210), produces an audio signature indicating both its position and relative motion orthogonally. shaded bars (214, 216) along the top and sides of the tablet (26) which comprise binary encoded sections, cause a composite of audio frequencies to be produced. The intersecting members (212, 222) of the movable cursor are orthogonally disposed with the x-axis member including seven phototransistors (220) as does the y-axis member (225), with each of the phototransistors (220, 223) being uniquely associated with an audio frequency oscillator (330-342, 334-356) whose outputs are mixed and combined (400) to provide a composite audio signature; and optically alignable with the shaded bars (214, 216). The movable intersecting members (214, 222) also comprise a plurality of windows (225, 227), with the intersecting windows (225, 227) being aligned so as to intersect over a marked response area (229) to define the unique position of the answer along the working surface (210).
