Assessing haptic properties for data representation

This paper describes the results of a series of forced choice design experiments investigating the discrimination of material properties using a PHANToM haptic device. Research has shown that the PHANToM is effective at displaying graphical information to blind people, but the techniques used so far have been very simple. Our experiments showed that subjects' discrimination of friction was significantly better than that of stiffness or the spatial period of sinusoidal textures, over the range of stimuli investigated. Thus, it is proposed that graphical data could be made more easily accessible to blind users by scaling the data values to friction rather than shape or size, as in traditional bar charts

Writer Identification Using Inexpensive Signal Processing Techniques

We propose to use novel and classical audio and text signal-processing and otherwise techniques for "inexpensive" fast writer identification tasks of scanned hand-written documents "visually". The "inexpensive" refers to the efficiency of the identification process in terms of CPU cycles while preserving decent accuracy for preliminary identification. This is a comparative study of multiple algorithm combinations in a pattern recognition pipeline implemented in Java around an open-source Modular Audio Recognition Framework (MARF) that can do a lot more beyond audio. We present our preliminary experimental findings in such an identification task. We simulate "visual" identification by "looking" at the hand-written document as a whole rather than trying to extract fine-grained features out of it prior classification.Comment: 9 pages; 1 figure; presented at CISSE'09 at http://conference.cisse2009.org/proceedings.aspx ; includes the the application source code; based on MARF described in arXiv:0905.123

Sonically enhanced interface toolkit

This paper describes an on-going research project investigating the design of a user-interface toolkit composed of sonically enhanced widgets. The motivation for this work is the same that motivated the creation of graphical interface toolkits, which was to simplify their construction, allowing designers who are not experts to create such interfaces; to ensure the sonically enhanced widgets are effective and improve usability; and to ensure the widgets use sound in a clear and consistent way across the interface

Gravitational waves from quasi-spherical black holes

A quasi-spherical approximation scheme, intended to apply to coalescing black holes, allows the waveforms of gravitational radiation to be computed by integrating ordinary differential equations.Comment: 4 revtex pages, 2 eps figure

Theoretical starting points: The field of emerging research universities

Efforts to prevent or persuade increased emphasis on academic research at state colleges and regional universities demonstrate how emerging fields of higher education can be influenced through various policies and incentives. Utilizing the concept of strategic action fields (Fligstein & McAdam, 2012), this paper explains changes in organizations by providing insight into how state policy influences constructed, meso-level social orders. Expanding on Pierre Bourdieu’s (1996) concept of fields, defined as the structured arena where practice occurs, strategic action fields extend the analysis to that of groups of actors competing for advantage and resources to increase their capabilities and reputations.Educatio

A list of websites and reading materials on strategy & complexity

The list has been developed based on a broad interpretation of the subject of ‘strategy & complexity’. Resources will therefore more, or less directly relate to ‘being strategic in the face of complexity’. Many of the articles and reports referred to in the attached bibliography can be accessed and downloaded from the internet. Most books can be found at amazon.com where you will often find a number of book reviews and summaries as well. Sometimes, reading the reviews will suffice and will give you the essence of the contents of the book after which you do not need to buy it. If the book looks interesting enough, buying options are easy
