Information-rich virtual environments (IRVEs) have been described as environments in which perceptual information is enhanced with abstract (or symbolic) information, such as text, numbers, images, audio, video, or hy...

There are a wide variety of ways to present information at the front of a classroom. These include chalk on a blackboard, markers on a whiteboard, pens on transparencies, and computer projection systems. While computer-based presentation systems provide many opportunities both in and out of the classroom, there may also be many limitations. In-class spontaneity and dynamic exposition might be restricted. Class preparation time might increase dramatically when compared to the amount required to prepare handwritten materials. Certain presentation techniques may no longer be available. This paper will introduce a computer-based presentation system modeled on handwritten transparencies. It will then discuss how it addresses the above issues as well as how it can be used in and out of the classroom. These will be explored in the context of its use while teaching an undergraduate discrete mathematics course. Copyright 2004 ACM.

The fundamental question for an information-rich virtual environment is how to access and display abstract information. We investigated two existing navigation techniques: Hand-Centered Object Manipulation Extending Ray-casting (HOMER) and Go-Go navigation, and two text layout techniques: within-the-world display (WWD) and heads-up display (HUD). Four search tasks were performed to measure participants' performance in a densely packed environment. HUD enabled significantly better performance than WWD and the Go-Go technique enabled better performance than the HOMER technique for most of the tasks. We found that using HOMER navigation combined with the WWD technique was significantly worse than other combinations for difficult naïve search tasks. Users also preferred the combination of Go-Go and HUD for all tasks.

computer displays can be helpful for making users aware of the remote presence of friends and family. In many of the research projects that have explored the use of novel displays, the real goal is to improve a user's sense of connectedness to those remote loved ones. However, very few have leveraged a user-centered design process or empirically studied the effects of using a display on users' sense of awareness and connectedness. In this paper, we present our multi-phase, user-centered design process for building displays that support awareness and connectedness: Presence Displays, which are physical, peripheral awareness displays of online presence of close friends or family. We present evidence, from a 5-week long field study, that these displays provide significantly better awareness of and connectedness to a loved one, than a traditional graphical display of online presence.

Small-scale classification schemes which are used extensively in the coordination of cooperative work are discussed. The study investigates the creation and use of a classification scheme for handling the system requirements during the redevelopment of a nation-wide information system. The requirements classification provide the software engineers with an important means of discretely balancing the contractual aspect of requirements engineering. The requirements classification is analyzed in terms of complementary concepts of boundary objects.
