Oculomotor control is the foundation of most biological visual systems, as well as an important component in the entire perceptual-motor system. We review some of the most basic principles of biological oculomotor systems, and explore their usefulness from both the biological and computational point of view. As an example of biomimetic oculomotor control, we present the state of our implementations and experimental results using the vestibulo-ocular-reflex and opto-kinetic-reflex paradigm.

MAD (Movie Authoring and Design) is a novel design and authoring system that facilitates the process of creating dynamic visual presentations such as motion pictures and lecture-demonstrations. MAD supports the process by enhancing the author's ability to structure and modify a presentation and to visualize the ultimate result. It does this by allowing both top-down design and bottom-up creation with a hierarchical multimedia document representation;by supporting the flexible inclusion and combination of words, images, sounds, and video sequences;and by providing realtime playback of the best approximation to the ultimate presentation that can be produced at any stage of the design process. MAD represents a paradigm shift from traditional methods of authoring and producing motion pictures. Its development therefore requires in-depth observation of a variety of users working on a variety of filmmaking projects. After describing the key concepts underlying MAD and the current, secondgeneration prototype software, we describe a number of interesting applications of MAD. In doing so, we review how we have worked with users in an iterative design process and how studies of the work of these users have informed key design issues. © 1996 ACM.

Even for the programmer, computer software can be a mysterious black box. But what if the programmer were able to give the box a good shake and listen to things rattle inside? Are there tools like the doctor's stethoscope that can help programmers listen to the heartbeat of their software? These are the kinds of questions we decided to explore by building LogoMedia, a sound-enhanced programming environment. LogoMedia supports the ability to associate non-speech audio with program events while the code is being developed. These associations cause subsequent test runs of the program to generate and manipulate sounds which can aid in the comprehension and analysis of the program's behavior.

Bringing icons to life 91

Bringing icons to life

Icons are used increasingly in interfaces because they are compact "universal" pictographic representations of computer functionality and processing. Animated icons can bring to life symbols representing complete applications or functions within an application, thereby clarifying their meaning, demonstrating their capabilities, and even explaining their method of use. To test this hypothesis, we carried out an iterative design of a set of animated painting icons that appear in the HyperCard tool palette. The design discipline restricted the animations to 10 to 20 second sequences of 22×20 pixel bit maps. User testing was carried out on two interfaces - one with the static icons, one with the animated icons. The results showed significant benefit from the animations in clarifying the purpose and functionality of the icons. ©1991 ACM.

The authors describe LOGOmotion, a programming environment that is visually enhanced, animated, unobtrusive, extensible, and monomorphic. The programmer can obtain with ease visual and animated presentations of the execution of programs written in the LOGO language. The programmer can also define new methods of program presentation by writing visualization procedures in LOGO without altering the original program code. Methods may include classical debugging tools such as traces, as well as more modern visualization aids such as the animation of program behavior. The design goals and fundamental principles of the system are discussed. Illustrations of its use and implementation are presented.< >

He is currently assistant group supervisor of the Computer Systems Group. Daniel M. Sunday:is a mathematician on the Principal Professional Staff of the Fleet Systems Department of The Johns Hopkins University Applied Physics Laboratory. He earned his Ph.D. in mathematics from the University of Minnesota in 1971 and did postdoctoral research on neural networks at the University of California at Berkeley. Since joining JHU/APL in 1980 Dr. Sunday has worked as a designer and developer of software systems with emphasis on medical imaging interactive graphics natural language interfaces and software standards. He was the network designer for the Headquarters Integrated Office System (HIOS) Network for the Army at the Pentagon. He is currently the lead software engineer on the Command Support At-Sea Experiment Project.

The Command Support At-Sea Experiment (CS@SE) provides experimental advanced graphics display systems consisting of large screen color displays and operator console color displays in the combat information center (CIC) of an Aegis cruiser and in the tactical flag command center (TFCC) of an aircraft carrier. CS@SE systems are designed to prototype potential command support capabilities in an at-sea environment to validate and refine requirements for planned production system upgrades. These systems use sophisticated color graphics techniques to provide real-time tactical displays that improve the availability of information to an operator by reducing clutter through the use of color, area fill, transparen overlays and intensity coding of track symbols. Interfaces wen developed with the Aegis Display System (ADS), Shipboarc Gridlock System with Auto-correlation (SGS/AC), Flag Dats Display System (FDDS) and Tomahawk Engagement Planning and Exercise Evaluation System (TEPEE) that provided the data for the presentation of a tactical display. Display elements included both real-time and over-the-horizon (OTH) surface track data, velocity leaders, tags, uncertainty ellipses, and history trails. The display also included filled land masses, country boundaries, commercial airways, cities, graphics overlays (i.e., operational areas), weapon system missile performance contours, and engagement plans. This paper describes the experiment, its installation and integration into the shipboard environments of an Aegis cruiser (USS Leyte Gulf ) and an aircraft carrier (USS America , its usage by the ships companies and embarked staffs, and the experiment result! and findings. Key conclusions of the experiment are: 1 Advanced graphics color displays can significantly enhance the ability of the warfighter to assimilate a complex tactical display. 2 Both ships reported a requirement for a correlated OTH and real-time track display with the ability to clearly differentiate the two types

The Visual computer 1988年第6期4卷 332-347页

作者： Haumann, David R. Parent, Richard E. Ohio Supercomputer Graphics Project The Ohio State University Department of Computer and Information Science Columbus 43212 OH 1224 Kinnear Road United States

Behavioral simulation is presented as a means to obtain complex global motion by simulating simple rules of behavior between locally related actors. A test-bed which has been developed to support experimentation with behavioral simulation is described. This test-bed has been used to create a library of physically behaving actors which can realistically reproduce the motion of flexible objects. The application of behavioral simulation to problems of motion specification in animation are described. The extension of this technique to simulate social behaviors is discussed. © 1988 Springer-Verlag.

To make computer programs for comprehensible, the presentation of program source text, program documentation, and program execution needs to be enhanced. A number of techniques and tools developed to achieve these ends are described. One of these is a design for the effective presentation of source text in the C programming language using high-quality digital typography; a processor which implements the design is also given. Some experimental evidence is summarized to demonstrate that the resulting source text presentation is significantly more readable and comprehensible than the presentation conventionally used today. Brief descriptions are given of two other techniques, the development of a system of structured program documentation incorporating both text and graphics and the portrayal of program execution with colored computer animation.< >

This paper describes and evaluates the design of four virtual controllers for use in rotating three-dimensional objects using the mouse. Three of four of these controllers are "new" in that they extend traditional direct manipulation techniques to a 3-D environment. User performance is compared during simple and complex rotation tasks. The results indicate faster performance for complex rotations using the new eontinuoos axes controllers compared to more traditional slider approaches. No significant differences in accuracy for complex rotations were found across the virtual controllers. A second study compared the best of these four virtual controllers (the Virtual Sphere) to a control device by Evans, Tanner and Wein. No significant differences either in time to complete rotation task or accuracy of performance were found. All but one subject indicated they preferred the Virtual Sphere because it seemed more "natural". © 1988 ACM.
