IBIS is a rule-based system that designs illustrations, a term we use to refer to pictures that are designed to satisfy an input communicative intent. The communicative intent is specified by a prioritized list of communicative goals. Each communicative goal specifies something the picture is to accomplish; for example, to show a property of an object, such as its location or shape, or to show a change in a property.

While retaining the currency and accuracy of the larger book, this abbreviated version focuses on topics essential for all beginners in computer graphics and provides expanded explanations for readers with little or no technical background.

We describe IGD's authoring facilities through an annotated excerpt from an editing session, emphasizing how the system's document model and user interface help support the creation of large documents.

We call part of a presentation that references material elsewhere a cross-reference. We are concerned here with how textual expressions can refer to parts of accompanying illustrations. The illustration to which a cross-reference refers should also satisfy the specific goal of identifying an object for the user.

However, no current commercial wearable system provides the graphical performance of even a typical modern desktop computer. In this paper, we describe two different experimental wearable graphics computers designed for prototyping augmented reality applications requiring fast 3D graphics.

This overview provides a high-level description of our work and surveys projects that reflect our two key research directions: 3D user interfaces (including virtual environments and augmented reality) and knowledge-based user interfaces.

Although designing a quality static 2D visualization is already a difficult task for most users, designing an interactive 3D one is even more challenging. To address this problem, we are developing AutoVisual, a rule-based system that designs interactive virtual worlds for visualizing and exploring multivariate relations.

Leaf images are captured with a digital camera and wirelessly transferred to the tablet. A computer vision component developed by our colleagues finds the best set of matching species, and we present the results in a zoomable user interface.

We organize issues into ones related to the environment, capturing, augmentation, display, and individual user differences. We also illuminate issues associated with more recent platforms such as handhelds or projector-camera systems. Throughout, we describe current approaches to addressing these problems, and suggest directions for future research.

Improvise is a knowledge-based system that can automatically create sequences of animated graphical illustrations to convey a wide variety of data. Our emphasis here is on describing how four important features of Improvise facilitate coordinated multimedia presentation design.

We will describe the history, how it evolved, what are the supporting arguments and what are its goals. The second part presents the NSF specific plan for this Initiative. We shall elaborate on the scientific content of this program, pose some open questions and outline the path of how we plan to achieve the goals. We shall discuss the identity of Computer Science as a scientific discipline and the consequences for funding.

Leaf images are captured with a head-worn digital video camera.

Most of the virtual worlds systems that have been so well publicized over the past five years use head-mounted displays that block off the wearer from the surrounding real world, effectively immersing her within a synthesized world.

Various kinds of notes document the patient's status over time, and comprise the official medical record for legal and billing purposes. Composing these notes encompasses several disparate, but interdependent subtasks.

Building on a custom Personal Health Record portal infrastructure that we have developed to provide access to real-time medication information for hospitalized patients, we are currently engaging clinicians and patients in user-centered design sessions to explore patient-friendly views of the information.

Some of the questions brought up in the last two years continue to be on the top of our minds: Why is telepresence not as common as we think it can be today? How much technology is too much in a telepresence system? Is there too much emphasis on creating an immersive telepresence system?

Interaction work in MR has predominantly focused on two areas: glove or wand-based virtual reality (VR) interactions and tangible user interfaces.

These problems include heterogeneity, size, distribution, and control of terminology.

The objective of this study was to evaluate two approaches for care provider identification employed within a commercial EHR at a large academic medical center. Methods We performed a retrospective review of EHR data for 121 patients in two cardiology wards during a four-week period.
