What's New


VL97 is the premier international conference on visual and multimedia computer languages. The aim of the conference is to discuss both formal methods and concrete applications in the area of visual and multimedia languages, as well as innovative methods for visual interaction and interaction with visual objects.


Summary of Conference Events


Tuesday, Sept. 23: Tutorials:
Tutorials introducing visual programming languages and visual information retrieval interfaces.

Wednesday - Friday, Sept. 24-26: Technical Program:
Papers, panels, keynotes, and the award-winners of the Visual Programming Challenge.

Saturday, Sept. 27: Workshop on Theory of Visual Languages

Location

The conference will be held at the Europa Palace Hotel in Capri, Italy. Capri is a beautiful island with many breathtaking views. It is located near the southern entrance of the Bay of Naples off the southwest coast of Italy. Capri is a single block of limestone with an area of 4 square miles and a population of 12,000 persons. The island has two suburbs: Capri and Anacapri. The latter is located at the top of the mountain. The island was colonized by the Greeks and later served as a vacation retreat for several Roman emperors, including Augustus and Tiberius, who built their villas there. The climate is particulary mild (with an average temperature range of 50-85 degrees F). Tourism is the primary economic resource. Many caves line the shore, the most famous of which is the shimmering Blue Grotto.

Description of the Tuesday Tutorials

TUTORIAL #1: (9:00) Introduction to Visual Programming Languages: Scaling-Up Issues

Instructors: Margaret M. Burnett and Rebecca Walpole
Department of Computer Science
Oregon State University
Email: {burnett, walpolr}@cs.orst.edu
Visual programming languages let the programmer sketch, point at, or demonstrate data relationships or transformations, rather than translate them into sequences of commands. The directness, immediacy and simplicity of visual programming languages are appealing. The question is, how can visual programming languages be effectively applied to large-scale programming problems while retaining these characteristics? The objectives of this tutorial are to present basic concepts of visual programming and provide an in-depth look at the issues for making visual programming languages suitable for solving large programming problems. Several existing visual programming languages as well as emerging research will be included as a way to explore in depth some of the issues in the scaling up problem.

Attendees should come away with the basic concepts of visual programming languages, an understanding of some of the issues important to scaling-up, and an understanding of solutions and attempted solutions to the scaling-up problem employed by a variety of visual programming languages.

TUTORIAL #2: (14:30) Visual Information Retrieval Interfaces (VIRIs)

Instructor: Robert Korfhage
Department of Information Science
University of Pittsburgh
Email: korfhage@lis.pitt.edu
The problem of perfoming information retrieval efficiently is a severe one in this era of full text and multimedia databases accesible over the Web. More than one hundred different visual interfaces have been developed to address this problem. Most enable the user to view and manipulate large numbers of documents to isolate the few relevant ones, while a few are aimed at a more detailed analysis of individual documents. This half day workshop reviews the status of VIRI development, focusing on the different metaphors and models being used, the different modes of user interaction available, and the types of results that have thus far been obtained.

The 1997 Visual Programming Challenge

The objective of the Visual Programming Challenge (VPC) is reward visual language approaches that offer the greatest promise to ease programming for all programmers, including public programmers, a term we use to denote those individuals who may have had little computer usage experience and perhaps no formal computer programming training.

The competition's problem domain requires quasi-real-time control of a robotic vehicle. The control of these robotic vehicles, made from LEGO® parts, represents a large class of control-type problems that are potentially interesting to public programmers. For instance, programming a robotic vehicle is similar to programming a robotic vacuum cleaner. Yet, the problem domain is sufficiently rich to reflect typical commercial problems as well.

This challenge is made possible through the support of National Science Foundation Grant IRI-9616242.


2nd International Workshop on Theory of Visual Languages

Following the success of TVL '96 which was held in conjunction with AVI '96 in Gubbio, Italy, in September '96, we are pleased to announce the second International Workshop on Theory of Visual Languages. TVL '97 will be held under the auspices of the IEEE Symposium on Visual Languages (VL '97) in Capri, Italy on September 27.

The TVL workshop is dedicated to discussions about different perspectives of visual languages and their theoretical foundations and aims at providing an open and creative platform for comparisons of different approaches to visual language theory. Research on visual language theory is widespread among different communities inside and outside the traditional visual language community. Several fields inside of computer science (such as artificial intelligence, diagrammatic reasoning, human computer interaction, formal language theory, graph grammars, databases, etc.) are working on visual languages as well as related neighbor disciplines like computational linguistics and cognitive science. The main aim of the workshop is to strengthen the dialogue between these diverse communities.
