This paper presents work aimed at supporting the design of temporal aspects of socio-technical systems. Time design is a framework for (a) analysing and representing temporal properties of the work domain, (b) generating design options that support timely, flexible and dependable function servicing, and (c) providing knowledge about the characteristics and biases of human temporal control behaviour. In support of the latter end, two microworld experiments that investigated temporal control decisions in a supervisory control task are presented. These experiments manipulated event rate, the duration of event rate blocks, the availability of online and offline event rate information, and the accuracy of this information. The studies identified conditions where attention to temporal information decreased and the use of conservative temporal control strategies increased

A course on pervasive computing should be structured around key functions throughout a systems development process to cover common underlying concerns throughout science and engineering disciplines - development of design rationale, prototyping, evaluation, and component reuse. However, broader considerations of usage context and appreciation for research and methodological contributions from other disciplines must be strongly factored into course planning. To achieve both goals, we suggest learning objectives, a general strategy and approach using case-based learning.
We introduce a new method for disambiguating word senses that exploits a nonlinear Kernel Principal Component Analysis (KPCA) technique to achieve accuracy superior to the best published individual models. We present ...

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 tutorial, 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.

As we have moved to a more technology-based classroom, much attention has been paid to using computers to present material. computer-based presentations can be a powerful tool for faculty, but as more and more students are coming to class with laptop and tablet computers, attention is being paid to questioning the opportunities this could present to these students in the form of enhanced note-taking opportunities. This paper explores the idea of faculty (rather than the students) using a computer note-taking system during student presentations to support interaction, evaluation, and feedback. Good annotations and records of a presentation can assist in more organized and effective feedback both during class as well as after class. It can also be beneficial in the evaluation of grades during the assignment stage of a faculty member's work. The techniques discussed can be extended to a wide variety of student presentation assignments.

Exploratory analysis of multidimensional data sets is challenging because of the difficulty in comprehending more than three dimensions. Two fundamental statistical principles for the exploratory analysis are (1) to examine each dimension first and then find relationships among dimensions, and (2) to try graphical displays first and then find numerical summaries (D.S. Moore, (1999). We implement these principles in a novel conceptual framework called the rank-by-feature framework. In the framework, users can choose a ranking criterion interesting to them and sort 1D or 2D axis-parallel projections according to the criterion. We introduce the rank-by-feature prism that is a color-coded lower-triangular matrix that guides users to desired features. Statistical graphs (histogram, boxplot, and scatterplot) and information visualization techniques (overview, coordination, and dynamic query) are combined to help users effectively traverse 1D and 2D axis-parallel projections, and finally to help them interactively find interesting features
