DYNAMIC DATA DISPLAY SYSTEM, AS FOR USE WITH EEG A dynamic display system is disclosed for discrete events of complex data that are carried by discrete electrical signals which indicate values in three coordinates as triads. One of the values may be an independent variable, e.g., time. A cathode ray tube display apparatus (television monitor) with a plane surface is actuated by format signals to exhibit a pictorial three-dimensional perspective field of reference somewhat in the figure of an elongate box viewed in perspective. The discrete electrical signals representative of data are processed to develop display signals to provide representative images in the field of reference. Specifically, as disclosed, the data events or elements are manifest in the form of lines or linear symbols that indicate coordinate values by symbol height and position. As disclosed, the independent variable, time, is scaled from an origin line in the field of reference to extend along the depth of perspective so that the linear symbols advance along the path of perspective to accomplish a dynamic display with the illusion of motion. The specific system herein displays EEG waves, effectively indicating the magnitude and frequency of individual brain waves with respect to time of occurrence. Consequently, a marching display is provided revealing fresh information together with a recent history of events in chronological order and in a concise and readily perceivable form. Additionally, recorded data may be later played back affording examination of a past history of EEG. Furthermore, color is utilized in the display to add still another dimension, stressing the ranges of frequency. A conventional television format is employed in which the linear symbols are formed along scanning lines of the television raster pattern, to provide a discrete and clear presentation.
