With the widespread deployment of broadband connections worldwide, software development and maintenance are increasingly being performed by multiple engineers, often working around-the-clock to maximize code churn rates. To ensure rapid quality assurance ...

Immersive virtual environment technology (IVET) allows developers to create simulated environments that can engage users in context relevant behaviors and that can produce relatively intense user experiences for purposes such as entertainment (e.g., ...

We present a general framework for cross-media annotation that can be used to support the many different forms and uses of annotation. Specifically, we discuss the need for digital annotation of printed materials and describe how various technologies ...

In video-on-demand (VOD) systems, as the size of the buffer allocated to user requests increases, initial latency and memory requirements increase. Hence, the buffer size must be minimized. The existing static buffer allocation scheme, however, determines ...

We have developed a visual syntax for representing concepts that are contingent on temporal properties (time-dependent semantics). A within-group (N=24) experiment was conducted to identify the representations that conveyed best a given semantic. We ...

This article presents an analysis of the human to human interactions in two public online newsgroups, one targeting the young generation and the other the elderly. The main goal of this study was to establish a better understanding of similarities and ...

TypeRight is a new tactile input device for text entry. It combines the advantages of tactile feedback with error prevention methods of word processors. TypeRight extends the standard keyboard so that the resistance to press each key becomes dynamically ...

This paper concerns the blind separation of P complex convolutive mixtures of N statistically independent complex sources, with underdetermined or noisy mixtures i.e. P
Keywords: Convolutive mixture, Differential blind source separation, Differential normalized kurtosis, Non-stationary signal, Underdetermined or noisy mixture

The Virtual Math Teams (VMT) project investigates the innovative use of online collaborative environments to support effective mathematical problem-solving by small groups of learners in an online community. A key research issue for us is to understand ...

A method is presented to rapidly incorporate real objects into virtual environments using laser scanned 3D models with color-based marker tracking. Both the real objects and their geometric models are put into a Mixed Environment (ME). In the ME, users ...

An essential aspect of mobile and ubiquitous computing research is evaluation within the expected usage context, including environment. When that environment is an urban center, it can be dynamic, expansive, and unpredictable. Methodologies that focus ...

The work of Pierre Schaeffer (theorist, composer and inventor of musique concrète) bears a complex relationship to the philosophical school of phenomenology. Although often seen as working at the periphery of this movement, this paper argues ...

Mobile information dissemination and sharing infrastructure is being proposed to support ubiquitous government. We report a Mobile Environmental Information System (MENVIS) that delivers auto-guided environmental tour information for New Jersey and New ...

We present a service providing real-time feedback to participants of small group meetings on the social dynamics of the meeting. The service measures and visualizes properties of participants' behaviour that are relevant to the social dynamics of the ...

This study is motivated by the increased need to understand human response to video-links, 3G telephony and avatars. We focus on response of participants to audiovisual presentations of talking heads, and examine the effect of noise and temporal misalignment ...
