While the main focus for this environment has been pre-built applications, there is certainly an opportunity for systems designed to facilitate programming new applications. Systems tools, such as Java, are of course readily available, but not generally usable by public programmers, i.e., programmers without training in either object oriented or imperative programming. What we have not seen is the equivalent of a spreadsheet language, designed for public programmers and making it possible for these people to build applications that collect and manipulate data, both from within the Web and from without. We discuss the application of the visual programming language, Formulate, to building distributed applications via the Web environment. Formulate has certain inherent advantages for application to this environment. Principle among these are: (1) it was designed for public programmers and (2) its internal evaluation algorithm is well suited for adaptation to a non deterministic distributed environment using symbolic URLs.","PeriodicalId":185794,"journal":{"name":"Proceedings. 1998 IEEE Symposium on Visual Languages (Cat.

Direct manipulations of the tabular layout may or may not result in the desired changes to the formulas. The user is forced to explore the individual cells to find, verify, and modify the formulas, which causes heavy cognitive overhead. We present a set of techniques that make these formulas and their resulting dataflow structure easily accessible while maintaining the natural appearance of the spreadsheet. Transient local views visualize dataflow structures associated with individual cells, while static global views and animated global explanations visually present the entire dataflow structure at once. Semantic navigation enables the user to navigate through the dataflow structure interactively, and visual editing techniques make it possible to construct formulas using graphical editing techniques. Central to these techniques is the use of animation and lightweight interaction for rapid and non-intrusive visualization. Our prototype implementation suggests that these techniques can greatly improve the expressive power of current spreadsheets as well as other applications that have rich underlying structures.","PeriodicalId":185794,"journal":{"name":"Proceedings. 1998 IEEE Symposium on Visual Languages (Cat.

Previously there were no visual languages for programming graph drawing algorithms, despite the inherently visual nature of the process. The languages which gave a diagrammatic view of graphs were not computationally complete and so could not be used to implement complex graph drawing algorithms. Hence current graph drawing tools are all text based. Recent developments in graph rewriting systems have produced computationally complete languages which give a visual view of graphs both whilst programming and during execution. Grrr, based on the Spider system, is a general purpose graph rewriting programming language which has now been extended in order to demonstrate the feasibility of visual graph drawing.","PeriodicalId":185794,"journal":{"name":"Proceedings. 1998 IEEE Symposium on Visual Languages (Cat.

MICE is to be used as the basis for the study of the visual design process applied to the development of TAO-based multimedia applications. The unifying model used in this approach is barred on Teleaction Objects (TAOs). TAOs are multimedia objects with attached knowledge structured as an active index. TAOs can be described using the TAOML extension of HTML. This allows for easy prototyping of distributed multimedia applications using a web browser as the user interface. The TAOML Builder tool allows the user to visually specify a TAO. The hypergraph is parsed for correctness using an underlying Boundary Symbol Relation grammar and the correct TAOML is output. TAOML can be translated into standard HTML using the TAOML Interpretor. The ICs for the application can be visually specified using the IC Builder. The IC Compiler produces the IC Manager which provides the run-time environment for the ICs.","PeriodicalId":185794,"journal":{"name":"Proceedings. 1998 IEEE Symposium on Visual Languages (Cat.

However, the textual scripting languages of these environments are difficult to use and require programming experience to code significant functionality. We propose a visual scripting language to help bridge the usability gap between the multimedia programming environment and its scripting language by cognitively simplifying the scripting task. Visual programming languages can be easier and faster to program in than textual languages, and visual code can be easier to understand. We explore our hypothesis by designing a multimedia programming environment with a visual scripting language.","PeriodicalId":185794,"journal":{"name":"Proceedings. 1998 IEEE Symposium on Visual Languages (Cat.

This creates a discontinuity between the drafting and solid modelling aspects of design, and the programming aspects which are becoming increasingly important as designers attempt to economise on their activities by building parameterised specifications. The declarative language LSD addresses this issue by applying visual programming to design. Here we present a formal model for objects in a design space and for operations on design objects. We also show how this model is integrated with LSD to provide a general mechanism for extending the language through the addition of new operations.","PeriodicalId":185794,"journal":{"name":"Proceedings. 1998 IEEE Symposium on Visual Languages (Cat.
