ABSTRACT:
An apparatus and method for the simultaneous, continuous and separate recording and measurement of head and body movements during standing and walking, including various optical markers mounted upon the head and the trunk of a test person, and a device for continuously receiving and recording optical signals from the markers, which device is stationarily fixed at a distance from the test person. The device being easy to handle, allows a time critical spectral analysis of the movement patterns, avoids overlapping of light tracings during recording of the optical signals, distortions of the measurements due to parallaxes when observing the body at various locations and central scotoma or an area of loss of visibility of the optical markers underneath of the device. At least three photoelectric cells being permanently mounted and fixed in a polygonal relation, and the device successively compares and levels quantitatively the values if the measurements of the photoelectric cells, which are permanently called and transmitted to a central data processing unit by a flow of data. Thus, the device installs a cylindrical vertical projection upon the standing or moving person being recorded.
