The first requirement of a "spatial mouse" is the ability to identify the object that it is aiming at. Among many possible technologies that can be employed for this purpose, possibly the best solution would be object recognition by machine vision. The problem, however, is that object recognition algorithms are not yet reliable enough or light enough for hand-held devices. This paper demonstrates that a simple object recognition algorithm can become a practical solution when augmented by interactivity. The user draw a circle around a target using a spatial mouse, and the mouse captures a series of camera frames. The frames can be easily stitched together to give a target image separated from the background, with which we need only additional steps of feature extraction and object classification. We present here results from two experiments with a few household objects.

Direct-manipulation editors for structured data are increasingly common. While such editors can greatly simplify the creation of structured data, there are few tools to simplify the creation of the editors themselves. This paper presents Citrus, a new programming language and user interface toolkit designed for this purpose. Citrus offers language-level support for constraints, restrictions and change notifications on primitive and aggregate data, mechanisms for automatically creating, removing, and reusing views as data changes, a library of widgets, layouts and behaviors for defining interactive views, and two comprehensive interactive editors as an interface to the language and toolkit itself. Together, these features support the creation of editors for a large class of data and code.

Decision-theoretic optimization is becoming a popular tool in the user interface community, but creating accurate cost (or utility) functions has become a bottleneck --- in most cases the numerous parameters of these functions are chosen manually, which is a tedious and error-prone process. This paper describes ARNAULD, a general interactive tool for eliciting user preferences concerning concrete outcomes and using this feedback to automatically learn a factored cost function. We empirically evaluate our machine learning algorithm and two automatic query generation approaches and report on an informal user study.

Traditional documentation for computer-based procedures is difficult to use: readers have trouble navigating long complex instructions, have trouble mapping from the text to display widgets, and waste time performing repetitive procedures. We propose a new class of improved documentation that we call follow-me documentation wizards. Follow-me documentation wizards step a user through a script representation of a procedure by highlighting portions of the text, as well application UI elements. This paper presents algorithms for automatically capturing follow-me documentation wizards by demonstration, through observing experts performing the procedure. We also present our DocWizards implementation on the Eclipse platform. We evaluate our system with an initial user study that showing that most users have a marked preference for this form of guidance over traditional documentation.

Informal prototyping tools have shown great potential in facilitating the early stage design of user interfaces. How-ever, continuous interactions, an important constituent of highly interactive interfaces, have not been well supported by previous tools. These interactions give continuous visual feedback, such as geometric changes of a graphical object, in response to continuous user input, such as the movement of a mouse. We built Monet, a sketch-based tool for proto-typing continuous interactions by demonstration. In Monet, designers can prototype continuous widgets and their states of interest using examples. They can also demonstrate com-pound behaviors involving multiple widgets by direct ma-nipulation. Monet allows continuous interactions to be eas-ily integrated with event-based, discrete interactions. Con-tinuous widgets can be embedded into storyboards and their states can condition or trigger storyboard transitions. Monet achieves these features by employing continuous function approximation and statistical classification techniques, without using any domain specific knowledge or assuming any application semantics. Informal feedback showed that Monet is a promising approach to enabling more complete tool support for early stage UI design.

System administrators work with many different tools to manage and fix complex hardware and software infrastructure in a rapidly paced work environment. Through extensive field studies, we observed that they often build and share custom tools for specific tasks that are not supported by vendor tools. Recent trends toward web-based management consoles offer many advantages but put an extra burden on system administrators, as customization requires web programming, which is beyond the skills of many system administrators. To meet their needs, we developed A1, a spreadsheet-based environment with a task-specific system-administration language for quickly creating small tools or migrating existing scripts to run as web portlets. Using A1, system administrators can build spreadsheets to access remote and heterogeneous systems, gather and integrate status data, and orchestrate control of disparate systems in a uniform way. A preliminary user study showed that in just a few hours, system administrators can learn to use A1 to build relatively complex tools from scratch.

Ever since the dawn of the digital computer, invention, innovation, and creativity have been a hallmark of the industry. The mainframe computer seemed for a while to be the real player with experts or at least highly trained professionals operating these large and expensive machines. Most users were allowed to see them through glass windows but "hands on" was a rare opportunity. In 1972, the Xerox Palo Alto Research Center (PARC), built a remarkable personal computer named the ALTO. Except for the visionaries at PARC and a few others, most people considered the personal computer a mere curiosity in this early period. Today, the personal computer has become a tool that very few imagined. What might be yet to come.While prognosticating about the future is a risky endeavor at best, perhaps we can obtain a look ahead with a straightforward review of the current status of personal computing. We will look at operating systems, application software and peripherals, however, the real goal of this talk is to see what the user interface, tools and interactions with this future computing environment might be or perhaps even should be. Will we still be using continuing variations of Doug Englebart's mouse in 2020 or might something new and much more advanced emerge? How might users seamlessly deal with terabytes of storage? How might multi-user environments be used and could multi-OS machines be an economic and generally available personal computing environment? Are there user experience issues that are critical in multi-OS environments? How might the user's display be different from today? Will tomorrow's displays be larger, have a significantly higher pixel density, be much more paper-like, etc.? Might electronic printers and their requisite paper output still be with us by 2025, for example? Will home and neighborhood network resources finally be a powerful ally of the computing environment? Many exciting opportunities and questions beg for answers and industry insight.This talk will attempt to peer into the near future to see what we might expect of the personal computing environment based on what we can extrapolate from current experience and technology directions. While the exactitude of such projections may be limited, taken as a whole, there is perhaps much that can be learned from such an exercise. Why do this? Charles Kettering, the great automotive inventor was asked why he spent so much time planning and thinking about the future. He wisely replied, "Because I am going to spend the rest of my life there." Thirty years ago, very few could have imagined all the wonderful things that personal computing has enabled. Perhaps we have just begun our exciting journey.

It is our pleasure to welcome you to Seattle for UIST 2005, the Eighteenth Annual ACM Symposium on User Interface Software and Technology. UIST 2005 continues in the tradition of being the premier forum for presentation of research innovations in the software and technology of human-computer interfaces. Sponsored by ACM's special interest groups on computer-human interaction (SIGCHI) and computer graphics (SIGGRAPH), UIST brings together researchers and practitioners from diverse areas that include traditional graphical & web user interfaces, tangible & ubiquitous computing, virtual & augmented reality, multimedia, new input & output devices, and CSCW. The intimate size, the single track, and comfortable surroundings make this symposium an ideal opportunity to exchange research results and implementation experiences.The call for papers attracted 158 full paper and TechNote submissions from 14 countries. The program committee accepted 30 of them (19%) that cover a variety of exciting topics, including mobile, physical, and voice interfaces, mouse & touch screen interaction, customization, and projector-based systems. In addition, the program includes a keynote from Gary Starkweather on personal computing in the 21st Century and two invited surveys by Susan Dray and Ken Goldberg on ethnography and the design of networked, interactive artworks, respectively. Posters, demos, and our third annual Doctoral Consortium will complete the program. You can find these contributions in the UIST conference companion, which is distributed at the conference. The UIST proceedings continue to be prepared in color and we hope that they serve as a valuable resource for researchers and practitioners. We have supplemented the proceedings with a DVD containing videos as appropriate for the papers, TechNotes, posters and demonstrations.

We present an evaluation of three mouse-based techniques for aligning digital images. We investigate the physical image alignment task and discuss the implications for interacting with virtual images. In a formal evaluation we show that a symmetric bimanual technique outperforms an asymmetric bimanual technique which in turn outperforms a unimanual technique. We show that even after mode switching times are removed, the symmetric technique outperforms the single mouse technique. Subjects also exhibited more parallel interaction using the symmetric technique than when using the asymmetric technique.

We explore the idea of using vision-based hand tracking over a constrained tabletop surface area to perform multi-finger and whole-hand gestural interactions with large displays from a distance. We develop bimanual techniques to support a variety of asymmetric and symmetric interactions, including fast targeting and navigation to all parts of a large display from the comfort of a desk and chair, as well as techniques that exploit the ability of the vision-based hand tracking system to provide multi-finger identification and full 2D hand segmentation. We also posit a design that allows for handling multiple concurrent users.
