Temporal Aspects of Tasks in the User Action Notation
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1990), TR-90-12
High software usability stems from good user interface design. Good designs invariably depend on an ability to understand and evaluate (and thereby improve) interface designs in the development process. Understanding and ...
Edge-Packing Planar Graphs by Cyclic Graphs
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1996-11-01), TR-96-15
Maximum G Edge-Packing is the problem of finding the maximum number of edge-disjoint isomorphic copies of a fixed guest graph G in a host graph H. This paper considers the cases where G and H are planar and G is cyclic. ...
Situational Analysis with the Task Mapping Model (TMM): A Tutorial
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1994), TR-94-16
The Task Mapping Model (TMM) is a user-centered analysis technique providing methods and notations for use in human-computer interaction (HCI) task analysis (Mayo & Hartson, 1993). The primary function of the TMM is to ...
Software Reuse Metrics and Models: A Survey
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1994), TR-94-27
This paper is no longer available. It has been replaced by TR-95-07.
Seeing Things Your Way: Information Visualization for a User-Centered Database of Computer Science Literature
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1994), TR-94-06
Project Envision is a user-centered multimedia database of computer science literature. Envision features powerful information visualization by displaying search results as a matrix of icons, with layout semantics under ...
Simulation Model Specifications: On the Role of Representation in the Model-Centered Sciences
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1994), TR-94-04
The old adage that "a problem correctly formulated is half solved" is rarely challenged. Model-centered problem solving relies critically on a correct model. Complete, clearly stated assumptions, a precise statement of ...
Measurement and Evaluation of Complex Navy Systems Designs
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1993), TR-93-23
The purpose of this paper is to present a multifaceted approach to the measurement and evaluation of complex Navy system designs with embedded realtime mission critical characteristics. The approach advocates the use of ...
An Empirical Study of Representation Methods for Reusable SoftwareComponents
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1994), TR-94-10
An empirical study of methods for representing reusable software components is described. Thirty-five subjects searched for reusable components in a database of UNIX tools using four different representation methods: ...
A Methodology for Synthesis of Interface Design Requirements
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1993), TR-93-10
This report is no longer available - TR-93-20 replaces it.
Project GEOSIM: The First Two Modules
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1991), TR-91-26
We present our initial report on Project GeoSim: a multidisciplinary effort involving members of the Departments of Geography and Computer Science at Virginia Tech to develop computer-aided instruction (CAI) software for ...
