"Conversational" Dialogues In Direct-Manipulation Interfaces, David G. Novick
"Conversational" Dialogues In Direct-Manipulation Interfaces, David G. Novick
Departmental Papers (CS)
This paper reports ongoing research in extending direct-manipulation interfaces by incorporating, via the direct-manipulation modality itself, interaction techniques that add kinds of language features associated with spoken conversation. The paper proposes means of implementing ways for a user of a direct-manipulation system to define new kinds of relations among objects in the interface.
Users And Uses Of Synchronous Business Communications Software, David G. Novick, Eleanor Wynn
Users And Uses Of Synchronous Business Communications Software, David G. Novick, Eleanor Wynn
Departmental Papers (CS)
To help designers and authors understand users' intentions and work practices for synchronous business communications in a systematic way, we used ethnographic and task-analytic techniques to collect, analyze and classify evidence of the activities of potential users as they conducted their work lives. The interactions we observed among our users took place through a variety of modalities. We found eight categories of tasks for the collaborative or interactive work in which our subjects engaged. Based on these data, we were able to classify roles of potential users of synchronous business communications software into a set of "archetypes" that characterize their …
Accounting For Domain Context In Evaluation, Meriem Chater, David G. Novick
Accounting For Domain Context In Evaluation, Meriem Chater, David G. Novick
Departmental Papers (CS)
Work is situated activity. Taking into account human factors in evaluation involves considering not only users but also their contexts of use. Consequently, the evaluation of systems — from video-games to safetycritical interfaces — requires analysis of context to understand not only the effect of context on usability but also the impact of artifacts' usability on users' environments. In the case of safety-critical systems (SCS), errors (by users or designers) may threaten human lives.
To assess the degree to which interface evaluation methods currently account for context, we have used the research strategy taxonomy of McGrath as a framework for …
