Concurrent overview and detail display system having process control capabilities

摘要

A cathode-ray tube, i.e., CRT, console having a plurality of CRT display faces with a data display on each CRT being divided among predetermined spatially oriented locations with correlated manually operable switches adjacent to each location area on the periphery of an associated CRT. The switches are used to control the display of additional and detailed information concerning an associated data area either on a CRT adjacent to the switches or on another adjacent CRT. Additional switches are provided on the console to enable an operator to respond to a data display by manipulating these additional switches to effect an adjustment or control of the data being displayed.
