This paper describes Visual Obliq, a userinterface development environment for constructing distributed, multi-user applications. Applications are created by designing the interface with a GUI-builder and embedding callback code in an interpreted language, in much the same way as one would build a traditional (non-distributed, single-user) application with a modern userinterface development environment. The resulting application can be run from within the GUI-builder for rapid turnaround or as a stand-alone executable. The Visual Obliq runtime provides abstractions and support for issues specific to distributed computing, such as replication, sharing, communication, and session management. We believe that the abstractions provided, the simplicity of the programming model, the rapid turnaround time, and the applicability to heterogeneous environments, make Visual Obliq a viable tool for authoring distributed applications and groupware.

Discussed are the results of an empirical study of constraint dataflow graphs in a number of graphical interface applications. One of the major findings is that over 90% of the dependencies in most applications are neighborhood dependencies that refer to slots in the same object, its parent, its children or its siblings. It is also shown how two approaches for reducing the storage costs of dataflow graphs-Hudson and Smith's microconstraints and a pure model dependency scheme-work in practice.

Physical widgets or phidgets are to physical userinterfaces what widgets are to graphical userinterfaces. Similar to widgets, phidgets abstract and package input and output devices: They hide implementation and construction details, they expose functionality through a well-defined API, and they have an (optional) on-screen interactive interface for displaying and controlling device state. Unlike widgets, phidgets also require: A connection manager to track how devices appear on-line;a way to link a software phidget with its physical counterpart;and a simulation mode to allow the programmer to develop, debug and test a physical interface even when no physical device is present. Our evaluation shows that everyday programmers using phidgets can rapidly develop physical interfaces.

Speech-based userinterfaces are growing in popularity. Unfortunately, the technology expertise required to build speech UIs precludes many individuals from participating in the speech interface design process. Furthermore, the time and knowledge costs of building even simple speech systems make it difficult for designers to iteratively design speech UIs. SUEDE, the speech interface prototyping tool we describe in this paper, allows designers to rapidly create prompt/response speech interfaces. It offers an electronically supported Wizard of Oz (WOz) technique that captures test data, allowing designers to analyze the interface after testing. This informal tool enables speech userinterface designers, even non-experts, to quickly create, test, and analyze speech userinterface prototypes.

In this paper we present BlinkBot - a hands free input interface to control and command a robot. BlinkBot explores the natural modality of gaze and blink to direct a robot to move an object from a location to another. The paper also explains detailed hardware and software implementation of the prototype system.

An effective userinterface is a cooperative interaction between humans and their technology. For that interaction to work, it needs to recognize the limitations and exploit the strengths of both parties. In this talk, I will concentrate on the human side of the equation. What do we know about human visual perceptual abilities that might have an impact on the design Of userinterfaces? The world presents us with more information than we call process. Just try to read this abstract and the next piece of prose at the same time. We cope with this problem by using attentional mechanisms to select a subset of the input for further processing. An interface might be designed to 'capture' attention, in order to induce a human to interact with it. Once the human is using an interface, that interface should 'guide' the user's attention in an intelligent manner. In recent decades, many of the rules of attentional capture and guidance have been worked out in the laboratory. I will illustrate some of the basic principles. For example: Do some colors grab attention better than others? Are faces special? When and why do people rail to "see" things that are right in front of their eyes?

Scientists use a variety of visualization techniques to help understand computational fluid dynamics (CFD) datasets, but the interfaces to these techniques are generally two-dimensional and therefore are separated from the 3D view. Both rapid interactive exploration of datasets and precise control over the parameters and placement of visualization techniques are required to understand complex phenomena contained in these datasets. In this paper, we present work in progress on a 3D userinterface for exploratory visualization of these datasets.
From a userinterface point of view, expert systems are different from applications in general in that the reasoning process of the system often defines the dialogue structure. This has several advantages, but there m...

Members of geographically distributed work groups often complain of a feeling of isolation and of not knowing 'who is around'. Argohalls attempt to solve this problem by integrating video icons, clustered into groups representing physical hallways, into the Argo telecollaboration system. Argo users can 'hang out' in hallways in order to keep track of the co-workers on their projects, and they can roam other hallways to 'run into' whoever happens to be there.

We describe some common problems experienced by users of computer-based text chat, and show how many of these problems relate to the loss of timing-specific information. We suggest that thinking of chat as a real-time streaming media data type, with status and channel indicators, might solve some of these problems. We then present a number of alternative chat interfaces along with results from user studies comparing and contrasting them both with each other and with the standard chat interface. These studies show some potential, but indicate that more work needs to be done.
