The Proof Animation 2.0 family of products is the latest achievement in Wolverine's ongoing commitment to produce innovative animation software. Proof Animation provides our customers with software capable of animating a vast array of applications while remaining easy to use. This product family runs on readily available, inexpensive PC hardware. Proof Animation is ASCII file-driven and features an open architecture, general purpose design, vector-based geometry with the ability to zoom in or out while maintaining crisp clear images, post-processing for maximum performance, built-in drawing tools for ease of creating animations, dynamic bar graphs and plots used to display statistics, a multi-windowing display, and a unique presentation-making capability. Because of its open architecture, Proof Animation can serve as the animation tool for models written in a wide variety of simulation and programming languages. Proof Animation's userinterface is menu-based and easily navigated using either a mouse or keyboard. Its superior performance assures smooth, realistic motion for animations of all sizes and degrees of complexity.

The expansion of multimedia networks and systems depends on real-time support for media streams and interactive multimedia services. Multimedia data are essentially continuous, heterogeneous, and isochronous, three characteristics with strong real-time implications when combined. At the same time, some multimedia services, like video-on-demand or distributed simulation, are real-time applications with sophisticated temporal functionalities in their userinterface. We analyze the main problems in building such real-time multimedia systems, and we discuss-under an architectural prospect-some technological solutions especially those regarding determinism and efficient synchronization in the storage, processing, and communication of audio and video data.< >

The VIMSYS project provides environmental scientists with the ability to perform content-based querying over a database of satellite images. This paper descriks the enduser query interface which facilitates identification of multiple object types, reduces emphasis on numerical data, and simplifies the use of numerous sets of parameters. To address these issues in a way that can be applied to similar databases, the end-user query interface utilizes abstract query structures called clusters, in addition to frames and links. We describe the requirements of the system, review commonly available query methods, discuss how the VIMSYS interface meets the needs of the audience, present user reaction to the prototype, and summarize other relevant details of VIMSYS.

Constraints have long been championed as a tool for userinterface construction. However, while certain constraint systems have established a user community, constraint- based userinterfaces have not yet been widely adopted. The pmxnise of this paper is that a major stumbling block to their pervasive use has been the emphasis on designing new interface toolkits rather than augmenting existing ones. The thesis of the work described in this paper is that it is possible, and practical, to convert an existing userinterface written in an imperative programming language into a similar userinterface implemented with constraints. This thesis is proved by example: the conversion of HotDraw into CoolDraw.

Current time-based presentation systems are rigid in that they assumethe running time of all components of a presentation is constant. Furthermore, most systems offer little or no supportfordynamically adapting the presentation quality to the (lack of) available system resources. In this paper, we introduce an object called a Pacer that is "timeelastic" in that it can adjust the quality of its presentation according to the amount of time available. Wehave implemented a direct manipulation graphical interface using pacersthat can automatically degradepresentation quality in a controlled fashion depending on the user's input rate and the speed of the rendering system.

Our approach to userinterface animation involves simulating the interaction of a user with the interface by synthetically generating the input events that drive the session. The interaction is made explicit by displaying the behavior of input devices audio-visually. Such "animation" is both educational and functional, and has the potential to become a powerful new medium in the graphical userinterface domain. We describe the construction of a general purpose tool for animating userinterfaces - the animation server. Clients drive the server with textual scripts that describe the interaction. These may contain constructs for obtaining application context information at runtime and synchronizing with other media servers. We present a few potential applications for animation servers, including a groupware package for loosely coupled collaboration.
