An Activity Centered Approach to Nonvisual Computer Interaction

The OpenKnowledge System: An Interaction-Centered Approach to Knowledge Sharing

The information that is made available through the semantic web will be accessed through complex programs (web-services, sensors, etc.) that may interact in sophisticated ways. Composition guided simply by the specifications of programs’ inputs and outputs is insufficient to obtain reliable aggregate performance hence the recognised need for process models to specify the interactions required b...

A User-Centered Approach to Affective Interaction

We have built eMoto, a mobile service for sending and receiving affective messages, with the explicit aim of addressing the inner experience of emotions. eMoto is a designed artifact that carries emotional experiences only achieved through interaction. Following on the theories of embodiment, we argue emotional experiences can not be design in only design for. eMoto is the result of a user-cent...

Activity-Centered Interaction Design: A Model-Driven Approach

1 Extended Abstract Activity theory has had a long history and a growing influence in the design professions broadly conceived and in interaction design in particular. Leading authorities, including Donald Norman, Bonnie Nardi, and others, have called for and argued the advantages of design approaches that focus more on the activities in which human users engage than on the users themselves. Hu...

An Approach to Multimodal Input Interpretation in Human-Computer Interaction

— Human-to-human conversation remains such a significant part of our working activities because of its naturalness. Multimodal interaction systems combine visual information with voice, gestures and other modalities to provide flexible and powerful dialogue approaches. The use of integrated multiple input modes enables users to benefit from the natural approach used in human communication. Howe...
