The growing interest in multimodal interface design is inspired in large part by the goals of supporting more transparent, flexible, efficient, and powerfully expressive means of human–computer interaction than in the past. Multimodal interfaces are expected to support a wider range of diverse applications, be usable by a broader spectrum of the average(More)
In this paper, we present the vision for an open, urban-scale wireless networking testbed, called CitySense, with the goal of supporting the development and evaluation of novel wireless systems that span an entire city. CitySense is currently under development and will consist of about 100 Linux-based embedded PCs outfitted with dual 802.11a/b/g radios and(More)
This paper 1 describes the design of a wireless urban sensor network testbed, CitySense. This first-of-its-kind testbed enables wireless networking researchers to perform repeatable experiments in a real-world environment. Studies that were previously limited to simulation and the laboratory can be validated through long-lived experiments in real-world(More)
CyberBELT allows a viewer to interact with a multithreaded documentary using a multi-modal interface. The viewer interacts with the documentary by speaking, pointing and looking around the display. The viewer selects the threads of the story to follow or lets the system navigate through the story. Feedback from the viewer evolves the story to present(More)
This paper presents a field study that compares natural language call routing with standard touch-tone menus. <i>Call routing</i> is the task of getting callers to the right place in the call center, which could be the appropriate live agent or automated service. <i>Natural language</i> call routing lets callers describe the reason for their call in their(More)
This whitepaper outlines our vision for developing an open, city-wide sensor network testbed, called CitySense, which will consist of 100+ nodes distributed throughout a city. Our current target for deployment is Cambridge, MA, see Figure 1. CitySense is intended to provide a powerful research facility for academic and industrial groups who want to(More)
