Investigation was carried out to estimate how efficiently can combined tasks of visual measurement and sensomotor reaction of choice be performed against tracking the sinusoidal signal at different sighting angles between their displays and different priority. It was found that, with a change in the sighting angle between the displays from 0 to 60 degrees, the time and number of tracking errors continuously increased; the probability of erroneous replies grew with an increase in the sighting angle to 30 degrees, remained essentially stable at angles of 30 and 45 degrees and decreased at 60 degrees. Combined performance of two equally important problems in case of an increase in the sighting angle between displays (from 30 to 45 degrees) was followed by a change in the structure of data acquisition.
