The development of userinterface systems has languished with the stability of desktop computing. Future systems, however, that are off-the-desktop, nomadic or physical in nature will involve new devices and new software systems for creating interactive applications. Simple usability testing is not adequate for evaluating complex systems. The problems with evaluating systems work are explored and a set of criteria for evaluating new UI systems work is presented.

This work presents an approach to the design of the software component of an Interactive System, which supports the generation of automatic task-oriented help. Help can easily be generated from the abstract formal specification of the associated system without any further effort. The architectural description is obtained in a task-driven way, where tasks are specified by indicating temporal ordering constraints using operators of a concurrent formal notation. The association of user tasks with software interaction objects, which inherit constraints of related tasks, gives the information to structure task-oriented help in an immediate way. The help given is thus more expressive with a consequent improvement in the usability of an Interactive System.

We present a generalized definition of scrolling that unifies a wide range of existing interaction techniques, from conventional scrolling through pan and zoom systems and fish-eye views. Furthermore it suggests a useful class of new scrolling techniques in which objects do not move across the display. These 'stationary scrolling' techniques do not exhibit either of two problems that plague spatial scrolling systems: discontinuity in salience and the undermining of the user's spatial memory.

Nested userinterface Components combine the concepts of Zooming userinterfaces (ZUIs) with recursive nesting of active graphical userinterface widgets. The resulting system of recursively nesting interface components has a number of desirable properties. The level of detail of the view of any widget component and its children, as well as the responsiveness of that component to the user's actions, can be tuned to the current visible size of that component on the screen. We distinguish between the interaction style of a component, and the semantic result that it produces. Only the latter is used to determine the geographic parameters for that component. In this way, very large and layered control problems can be presented to the user as a cohesive and readily navigable visual surface. It becomes straightforward to layout interaction semantics that are best handled by recursion, such as filters composed of nested expressions.

We identify different types of failures in a voice userinterface application, from both developer and user perspectives. Our preliminary experiment suggests that user-perceived Pattern Match Failure may have a strong negative effect on user frustration;based on this result, we conduct power analysis to obtain more conclusive results in a future experiment.

Nowadays, novice users often turn to digital tutorials for guidance in software. However, searching and utilizing the tutorial remains a challenge due to the request for proper problem articulation, extensive searches and mind-intensive follow-through. We introduce "Docent", a system designed to bridge this knowledge-seeking gap. Powered by Large Language Models (LLMs), Docent takes vague user input and recent digital operation contexts to reason, seek, and present the most relevant tutorials in-situ. We assume that Docent smooths the user experience and facilitates learning of the software.

In this paper, we describe our work on developing a system to support the personalization of a captured public experience. Specifically, we are interested in providing students with the ability to personalize the capture of the lecture experiences as part of the Classroom 2000 project. We discuss the issues and challenges involved in designing a system that performs live integration of personal streams of information with multiple other streams of information made available to it through an environment designed to capture public information.

The Cage is an easy to use 3D grid. Built into a 3D modeler, it provides a visualized reference coordinate system that helps the user to orient himself in 3D space, and that supports efficient alignment and snapping methods. It can be adapted with a single mouse click to any new viewing situation and reference system. The Cage was implemented in C++ under Open Inventor on Silicon Graphics workstations. It was tested as a part of a 3D authoring tool for virtual TV studios.

We describe local tools, a general interaction technique that replaces traditional tool palettes. A collection of tools sit on the worksurface along with the data. Each tool can be picked up (where it replaces the cursor), used, and then put down anywhere on the worksurface. There is a toolbox for organizing the tools. These local tools were implemented in Pad++ as part of KidPad, an application for children.
