Using linear programming, an interactive graphic display system has been implemented to solve the region design problem of partitioning a region into N nonoverlapping subregions in such a way that their areas are in specified proportions and that the total cost of servicing them is a minimum. In a conversational manner, a user can easily obtain different partitionings by specifying and modifying the boundary, the service centers' locations, the area proportions, and the cost functions. Examples are included. [ABSTRACT FROM AUTHOR]

A television-like scanned-display system has been successfully Implemented on a Honeywell DDP424 computer installation. The scanned image is stored in the core memory of the computer, and software scan conversion is used to convert the rectangular coordinates of a point to the appropriate word and bit In an output display array in core storage. Results thus far Indicate that flicker-free displays of large amounts of data are possible with reasonably fast graphical interaction. A scanned Image of size 240 X 254 points is displayed at a 30 frame-per-second rate. [ABSTRACT FROM AUTHOR]

The design and implementation of the C.S.I.R.O. operating system, DAD, is described in detail. This system is designed for the Control Data 3600 using a large drum backing store and is intended to allow the integration of a remote console (display) subsystem into a conventional job stack environment, The use of the drums, the buffering of input and output on slow peripherals, and the execution of normal job stack work are described. The display subsystem is described only as it integrates into the rest of the system. The techniques found useful in the development of DAD are given, and an assessment is made of the validity of various design decisions. Performance figures based on several months of operation are tabulated. [ABSTRACT FROM AUTHOR]

The article discusses a computer technique for displaying two types of n-dimensional hyperobjects and for n-dimensional rotation. Any n-dimensional hyperobject could then be manipulated mathematically by a digital computer. The final three-dimensional projection of the rotating hyperobject could be drawn automatically on a computer-controlled visual display device as a stereoscopic movie. The most common form of projection in three-dimensional space is the perspective projection of an object as seen by each of the two eyes. A hyperobject in n-dimensional space can be represented as straight-line segments connecting an ordered set of points. The stereoscopic pair of two-dimensional perspective projections of the three-dimensional projection of the hyperobject are calculated by the computer and automatically plotted un a single frame of film. The movies have already been useful in extending knowledge of three-dimensional perspective projections to higher dimensions. The techniques have been applied to real-time graphical displays so that the user can rotate, translate, and manipulate hyperobjects and hyperdata and immediately see the results on a graphical display.

The tremendous output of the high-speed computer has far outstripped the modern executive's ability to examine, absorb, and use all the information generated in his day-to-day decision making. But this imbalance between the machine and the manager is now being corrected through the development of computer graphics. In this article, the authors examine a number of different plotting techniques--from two-dimensional pictorial maps to 3-D model making and from black and white to full color. The great advantage is that with graphics the data output can be communicated to the manager in more comprehensible, intelligible, and usable ways than by conventional computer reports.

The article discusses whether the proposed Nike-X anti-missile system in the U.S. is worthwhile. Opponents of the system claim that a good offense is the best defense and that Nike-X will not save enough lives to save the nation. Elements that make-up the Nike-X system include a multi-function array radar (MAR), a missile site radar, Zeus missile, Sprint missile and associated information-display and data processing equipment.

A stereographic display terminal has been produced using the raster display (BRAD) recently developed at Brookhaven. The system uses a rotating refresh memory to feed standard television monitors. To produce a stereographic display the computer calculates the projected video images of an object, viewed from two separated paints. The resulting video maps are stored on separate refresh bands of the rotating memory. The two output signals are connected to separate color guns of a color television monitor, thus creating superimposed image on the screen. Optical separation is achieved by viewing the image through color filters. The display is interactive and can be viewed by a large group of people at the same time. [ABSTRACT FROM AUTHOR]

Ability of the console to plot tens of thousands of points; Use of a technique that programmatically generates a binary image of the desired display in a computer; Use of a standard television monitor as display device; Drawbacks of the technique.

The article focuses on new graphic input/output cathode ray tube (CRT) display systems. Interest in man-computer communication continues to be a preoccupying development topic for many computer and peripheral manufacturers. One result has been the development of graphical input/output information display systems that have at their center CRT inquiry-type consoles. UNIVAC has introduced the UNISCOPE 300, a visual communication terminal designed for instant viewing of computer stored information. Typical applications for the UNISCOPE 300 include the provision of up-to-the-minute information for businessmen on all facets of their operations, such as sales information and inventory figures, the expediting of travel reservations, and faster customer service at tellers' windows in banks. The equipment consists of a keyboard with 61 keys, a cathode ray tube display screen and an associated control unit. The device may be used as a self-contained unit or in a multi-station version providing up to 58 keyboard displays directed by one control unit.

The article discusses the author's view regarding new teaching aids. He discusses the book of Richard I. Miller that talks about selecting aids for teaching. He mentions that it is irrelevant for it tends to increase the work of a group that should be obsolete. Moreover, he mentions that it is impossible to select the appropriate media until the system can identify its operational objectives. Thus, any selected media will continue to operate as an independent system apart from the educational program.
