In this paper, a valid frequency range of throat signal analyses is presented. Compare to speech signals, the throat signals have many differences in the amount of information. In this context, targeting on throat signals to find valid frequency range is one of the most important analyses for the development of new breed of feature extraction algorithm. In this respect, using analysis similarity of throat signals feature distribution and correlation analysis of throat signals in the frequency domain, the frequency range can be found with effective and quick response time to be applied to a voice command recognition system using neck-microphone. As a result, the proposed frequency range is from 200Hz (center frequency) to 2001Hz (center frequency). For the neck-microphone voice command system using the proposed frequency range, a significant reduction in time complexity of 25% can be achieved without any loss in recognition rate.

We introduce HIPerPaper, a novel digital pen and paper interface that enables natural interaction with a 31.8 by 7.5 foot tiled wall display of 268,720,000 pixels. HIPerPaper provides a flexible, portable, and inexpensive medium for interacting with large high-resolution wall displays. While the size and resolution of such displays allow visualization of data sets of a scale not previously possible, mechanisms for interacting with wall displays remain challenging. HIPerPaper enables multiple concurrent users to select, move, scale, and rotate objects on a high-dimension wall display.
While recent advances in graphics, display, and computer hardware support ultra-scale visualizations of a tremendous amount of data sets, mechanisms for interacting with this information on large high-resolution wall ...

While recent advances in graphics, display, and computer hardware support ultra-scale visualizations of a tremendous amount of data sets, mechanisms for interacting with this information on large high-resolution wall displays are still under investigation. Different issues in terms of user interface, ergonomics, multi-user interaction, and system flexibility arise while facing ultra-scale wall displays and none of the introduced approaches fully address them. We introduce HIPerPaper, a novel digital pen and paper interface that enables natural interaction with the HIPerSpace wall, a 31.8 by 7.5 foot tiled wall display of 268,720,000 pixels. HIPerPaper provides a flexible, portable, and inexpensive medium for interacting with large high-resolution wall displays.

Dynapad is a development environment designed to support research prototyping of multiscale workspaces. In this paper we describe applications designed to facilitate visual access to and spatial organization of digital photo collections and personal libraries of PDF documents. The research objective is to explore a generalization of the notion of a "pile" as a foundation for a versatile suite of tools to provide unobtrusive assistance for organizing collections and other sensemaking activities. We detail the architecture underlying the applications, explain how it supports diverse functionality and interaction styles, and abstract a set of principles for designing spatial tools.
We explore and extend the metaphor of "piles" to include computationally-enriched piles, portable regions of automation in Dynapad, a multiscale workspace. We describe these collection-management tools and h...

This paper describes an interdisciplinary research collaboration to design a human-centered driver assistance system. Driving behavior is captured using a novel intelligent vehicle test bed. The synchronized capture of driver behavior and driving context provides an empirical basis for the design and evaluation.

The Ecological cognition perspective emphasizes the fact that humancognition is adaptive to the constraints of the context of task performance. People are good at developing strategies for task performance that take advantage of the informational affordances of the task environment. Therefore, if we wish to understand humancognition, we must look beyond the skin and skull of the individual to the material and social structures with which the mind interacts. Of course, material artifacts and social arrangements are elements of adaptive processes as well. Material artifacts are often crystallizations of regularities in the task environment and they develop over time, changing adaptively to fit the constraints of the task, the properties of the task performers, and the other artifacts employed in the task performance. Such changes in the material artifacts change the informational affordances of the task environment, which creates new opportunities for the development of strategies. Thus, humancognition and the material supports of humancognition must be seen as a co-adaptive system. Similarly, in complex work settings where two or more persons jointly perform tasks, social arrangements are enacted anew each time a socially distributed task is performed. Strategies for the social division of cognitive labor are also part of this co-adaptive system, both constraining and being constrained by mental and material artifacts. These interlocked co-adaptive systems suggest a cognitive ecology. It's a compelling way of talking about such systems. Can it be more than a metaphor?
