Abstract

A system including a touch pressure-sensitive transducer and a computer responsive thereto for producing a sentic cycle and for recording touch expression in the course of which cycle different emotions are expressed and generated by applying appropriate finger pressure to the transducer actuator. Stored in the memory of the computer is a set of words representing the different emotions, the computer being programmed to sequentially select these words at timed intervals and to audibly reproduce the selected word. Each word is followed by a series of time-spaced audible start clicks, each commanding the subject when to express with finger pressure on the transducer actuator. The signals yielded by the transducer reflecting vector components of the applied finger pressure are processed in the computer whose display terminal then presents on its screen a sentogram, the shape of which characterizes the emotion sensed by the transducer. Single or averaged sentograms developed by the subject during a particular sentic cycle are stored in the computer for comparison with those produced by the same subject in subsequent cycles to gauge the degree to which the subject's emotional responses may have changed. Stored or "live" sentograms can also be used to impart emotional content to graphically reproduced animated figures or to reproduced music modulated as a function of the sentogram, or to movement activated according to its dynamic form.
