FIELD: medicine.
SUBSTANCE: invention can be used for assessing and development of ability of distinguishing objects on masking background by urban video surveillance operators, scouts, snipers, air-traffic dispatchers, operators of radar stations, and other experts of similar profile. Device comprises panel with images of objects on masking background, pulse counter, chronometer and stylus with metal tip, which through signal lamp is connected with pulses counter, whose outputs are led to key elements, whose outputs are connected to timer on/off switch. Besides, outputs of pulse counter are connected to digital indicator with binary to digital code converter at input, and image contours are metallized and connected to housing via control switches.
EFFECT: automation of assessment process, training and improvement of accuracy, efficiency and objectivity of measurements, possibility of own psychophysical indices study by tested person.
