The fundamental contribution of Semiotic Engineering to human-computer interaction has been to propose and establish a discourse to conceptualize HCI not primarily about how users interact with computers but as computer-mediated communication between designers and users at interaction time. It represents an important contribution to explore the future of HCI beyond the focus of usability and in...

Investigations of ethics in product design have been limited. This paper offers an insight into designer’s perceptions of responsibilities over three levels of expertise; first year design students, graduating design students, and design practitioners. The paper presents the use of some novel methods including triad and card sorting to uncover perceptions of designers responsibilities. The find...

This paper presents a method for assessing the quality of a progressive design process by measuring the profitability of the product that the process generates. The proposed approach uses separations, a type of problem decomposition, to model progressive design processes. The subproblems in the separations correspond roughly to phases in the progressive design processes. The proposed method sim...

Little is known about the development of social e-atmospherics. And yet, e-atmospherics have motivated an emerging body of research which reports that both better layouts and ‘recognized’ atmospherics encourage consumers to modify their shopping habits. While the literature has analyzed mainly the functional (design) aspect of e-atmospherics, little has been done in terms of linking its charact...

For many years I have been interested in how design works, and in how to support designers doing design. Inspired by tools like Macsyma (and later Mathematica, etc.), I became interested in building end-user languages and tools that are in a sense general-purpose systems and yet that end users can tailor or customize to correspond to their own needs. Whether there are specific structures and op...

This document provides advice to the designers of digital communication equipment, link-layer protocols, and packet-switched local networks (collectively referred to as subnetworks), who wish to support the Internet protocols but may be unfamiliar with the Internet architecture and the implications of their design choices on the performance and efficiency of the Internet. Karn, et al. Best Curr...

This Report was written primarily for use as a colorimetry tutorial for any MPEG users who may feel confused by the plethora of descriptive data contained in the MPEG data-stream. It is not intended to be an exhaustive treatise on basic colorimetry or even on television colorimetry; that would require a very much larger document. There are many books on the subject, but two are of particular re...

The design of learning environments is a fundamental part of education research today. In this article, we put forth a design method, medium-based design (MBD), to create useful learning environments that foster inquiry, support artifact construction, and enable interaction with targeted learning content through a medium.
