Software architects have techniques to deal with many quality attributes such as performance, reliability, and maintainability. Usability, however, has traditionally been concerned primarily with presentation and not been a concern of software architects beyond separating the user interface from the remainder of the application. In this paper, we present usability-supporting architectural patterns. Each pattern describes a usability concern that is not supported by separation alone. For each concern, a usability-supporting architectural pattern provides the forces from the characteristics of the task and environment, the human, and the state of the software to motivate an implementation independent solution cast in terms of the responsibilities that must be fulfilled to satisfy the forces. Furthermore, each pattern includes a sample solution implemented in the context of an overriding separation based pattern such as J2EE Model View Controller.
We seek to improve the experience of using pen computing devices by augmenting them with haptic, tactile feedback displays. We present the design of the haptic display for pen computers, and explore interaction techni...

Interviews of twenty-six Industrial Engineering students and graduates were conducted during the first year of a three year study of the unexpected attainment of gender parity in the School of Industrial Engineering at the University of Oklahoma (OU). An analysis of the pattern of participant responses gives insight into industrial engineering (IE) student perceptions of IE. The perceptions were grouped into three broad themes: Career Profile, Discipline Profile, and Discipline Meta-Profile. The Career Profile includes the availability of multiple career paths and flexible careers in this discipline in addition to the potential for the attainment of status through entry into management. People-oriented, broad, and systems-oriented are terms that were used to describe the Discipline Profile. Discipline Meta-Profile is used to describe the participant's perception of other people's perceptions of industrial engineering (i.e. what IE students think other people think). These participants felt that other engineers think of IE as easy, or "imaginary" engineering. The participants also thought that the discipline is invisible, even to other engineers. While the meta-perception of IE might seem to be problematic for the discipline, many of the participants reject the meta-perception. Some participants recognized that IE's focus on people and systems is simply different than other engineering disciplines, not necessarily easier. Other participants felt the potential to enter into management outweighed the discipline meta-perception. One student summarized the response particularly well when he noted that IE is "inviteful" engineering.

In this paper, low-complexity block-constrained trellis coded quantization (BC-TCQ) structures are introduced, and a predictive BC-TCQ encoding method is developed for quantization of line spectrum frequencies (LSF) parameters for wideband speech coding applications. The performance is compared to the linear predictive coding (LPC) vector quantizers used in the AMR-WB (ITUG.722.2) speech coding standard, demonstrating reduction in spectral distortion and significant reduction in encoding complexity.

computer users deal with large amount of personal media data and they often face problems in managing and exploring them. The paper presents an innovative approach, Semantic Regions that are rectangular regions directly drawn on 2D space with semantics so that their layout can form users' various mental models toward the personal media data. A prototype personal media exploring application, MediaFinder, based on the concept of Semantic Regions is presented. Usability tests will be conducted to evaluate the Semantic Regions as a personal media management model including organization, search, navigation, indexing, meaning extraction, and distribution.
