IDS of OK "Buran"
This is a rough translation of the article titled "Information display system of the spacecraft "Buran"" by Tiapchenko. 
Information display system - this is a collection of means and methods of ensuring the activities of operators in the management and maintenance of complex objects. Unlike the other radioelectronic equipment (REA), the IDS has two different interfaces: Instrumentation (PI) and ergonomic interface(EI). PI - This is the hardware and software part of the IDS, designed to interface display tools (CO) and controls (OC) with subsystems and spacecraft structures. EI - these are the tools and methods for interfacing between man and machine (spacecraft). The technical level of PI depends on the technical level of electronic and computer technology (EWT), electrical engineering and methods of data exchange with spacecraft systems. In this aspect, the IDS does not differ from the REA of general-purpose control systems (CS), and therefore there are no limitations for microminiaturization of it - there are no limitations in weight and dimensions. The external part of the EI is the front panel of the console or dashboard, on which CO and OU are installed. Miniaturization, as a method of reducing the mass and dimensions, adopted in the REA for wide use, is practically inapplicable in EI, since the size of the OU, for example, depends on the capabilities of the human motoric apparatus (sizes of fingers, hands, legs, etc.). The dimensions of the selected COs depend on the size of the information displayed on them. The size of symbols or inscriptions depends on their distance from human eyes, etc.
