Multimodal Interactive Maps: Designing for Human Performance.
Peer reviewed Peer reviewed
Oviatt, Sharon – Human-Computer Interaction, 1997
Analyzes interfaces supporting spoken, pen-based, and multimodal input for their effectiveness in interacting with interactive map systems. Results identified performance difficulties with speech-only map interactions that declined substantially when people could interact multimodally. Analyses also indicated that map displays can be structured to…

Toward an Information Visualization Workspace: Combining Multiple Means of Expression.
Peer reviewed Peer reviewed
Roth, Steven F.; Chuah, Mei C.; Kerpedjiev, Stephan; Kolojejchick, John A.; Lucas, Peter – Human-Computer Interaction, 1997
Presents an information visualization workspace in which users are able to explore data presented in diverse but coordinated formats using related systems called Visage, SAGE, and selective dynamic manipulation (SDM). Discusses four dimensions for analyzing user interfaces that reveal the combination of design approaches needed for visualizations…

Introduction to this Special Issue on Multimodal Interfaces.
Peer reviewed Peer reviewed
Oviatt, Sharon; Wahlster, Wolfgang – Human-Computer Interaction, 1997
Introduces five articles in a special journal issue devoted to research about, design of, and use of multimodal interfaces. Article highlights include: algebra instruction; presentation of data summaries; interaction with complex spatial displays (maps); access to computing for the visually impaired; and design for portable devices for use in…

A Mechanism for Multimodal Presentation Planning Based on Agent Cooperation and Negotiation.
Peer reviewed Peer reviewed
Han, Yi; Zukerman, Ingrid – Human-Computer Interaction, 1997
Introduces a multiagent architecture based on the blackboard system that enables different processes that perform multimodal presentation planning to communicate with each other. Describes a constraint propagation mechanism that transfers plan constraints from one level of the presentation planning process to the next. Discusses the cooperation…

Representing Cognitive Activity in Complex Tasks.
Peer reviewed Peer reviewed
Barnard, Philip J.; May, Jon – Human-Computer Interaction, 1999
Interacting cognitive subsystems (ICS) is proposed as a unified cognitive theory that can be used as the basis for representations in human-computer interaction, and two approaches based on the theory are described: one entails the description of cognitive task models, and the other entails the production of less complete diagrammatic notations.…

Cognitive Support: Extending Human Knowledge and Processing Capacities.
Peer reviewed Peer reviewed
Neerincx, Mark A.; de Greef, H. Paul – Human-Computer Interaction, 1998
This study of 40 undergraduates examined whether aiding as cognitive support (i.e., offering computer users knowledge they are missing) can supplement lack of knowledge and capacity under tasks with high mental loading, such as dealing with irregularities in process control. Users of a railway traffic control simulator dealt better and faster with…
