(54) CONSTITUTION FOR REGISTRATION OF THE POSITION OF THE HEAD OF THE OBSERVER REGARDING THE OBJECT OF THE OBSERVATION

The invention relates to medical technology and can be used for psychological, neurophysiological and ergonomic experiments. A device is known for recording the position of the observer’s head relative to the object of observation, which contains a screen and a series-connected lens mounted on the head of the subject, and a recording device made in the form of serially connected photo-receivers optically connected to the lens, an amplifier, two counters, a reference generator and a number converter pulses to the coordinates of the location of the light beam on the screen LT-J. A disadvantage of the known device for detecting the position of the observer’s head relative to the object of observation is that it does not register accurately enough because it does not determine whether the change in the coordinates of the location of the light beam on the screen is caused by a linear displacement, rotation, or joint action of the linear displacement and rotation of the head, and the proportion of these effects. In addition, the presence of an optical-mechanical node scanning the light beam limits the speed of the device. The aim of the invention is to increase accuracy. This goal is achieved by the fact that the device for detecting the position of the observer's head relative to the object has a display of the screen and a series-connected lens and a registering device, equipped with point sources of light located on the screen, and the registering device includes series-connected television transmitting tubes facilities and converter ko. ordinat.

The observation contains a screen t on the result of the implementation of the observation by the observer, the point sources 2 and 3 are interfered with by the cohore of the noi-tion of the point coordinates 2 and 3 of the snow and determine the significant coordinate line directed to the screen and attached to the 5 Observer, the accuracy of the recorder is increased, consisting of the position of the observer's head in series connected television relative to the object of observation. By means of a transmitting tube 5, optically connecting the number of screens, objective, with a pin, the meter 6 coordinates and recording devices up to three dinaty point objects and the converter can be obtained a device for 7 coordinates, all the linear and angular coordinates the following head position is working in general
