The Cognitive Walkthrough methodology was developed in an effort to bring cognitive theory closer to practice; to enhance the design and evaluation of use interfaces in industrial settings. For the first time, small teams of professional developers have used this method to critique three complex software systems. In this paper we report evidence about how(More)
Computing environments which involve many interacting devices are a challenge for system and user interface designers. A prototype of a multiple-device application consisting of a personal digital assistant (PDA) that operates in conjunction with interactive television (ITV) was developed from user requirements for a real estate information service. The(More)
The cognitive walkthrough is a technique for evaluating the design of a user interface, with speciaJ attention to how well the interface supports “exploratory learning,” i.e., first-time use without formal training. The evaluation can be performed by the system’s designers in the e,arly stages of design, before empirical user testing is possible. Early(More)
Users of personal computers must deal with frequent major upgrades of software packages. Major upgrades typically provide increased functionality without changing the conceptual framework of the program, but they may force the user to learn how to use new menus, dialog boxes, and other controls. We suggest that early versions of a program provide a natural(More)
Given the importance of Situation Awareness (SA) in military operations, there is a critical need for a realtime, unobtrusive tool that objectively and reliably measures warfighters’ SA in both training and operations. Just as the requirement for improved access to SA measures has become vital, it is now commonplace for military team communications to be(More)
INTRODUCTION Letting users speak commands to the systems they are interacting with has been tried in various domains. Examples include a range of computer applications, as well as more narrowly defined domains such as aircraft systems. Using speech to control computers has never caught on in a big way, however, and in aircraft it has been limited to a few(More)
US WEST Advanced Technologies conducted an experiment using the "Wizard-of-Oz" paradigm. We compared a simulated speech recognition interface ("wizard") for a basic voice mail application to functionally similar touch-tone and operator assisted versions. This poster abstract highlights the results of this experiment, focussing on performance times and(More)
