Activity-Centered Design: An Ecological Approach to by Geraldine Gay, Helene Hembrooke

By Geraldine Gay, Helene Hembrooke

The shift within the perform of human-computer interplay (HCI) layout from user-centered to context-based layout marks an important switch in concentration. With context-based layout, designers begin now not with a preconceived suggestion of what clients should still do, yet with an realizing of what clients really do. Context-based layout specializes in the placement within which the expertise may be used -- the actions when it comes to it and their social contexts. Designers also needs to detect that advent of the expertise itself alterations the location; with a purpose to layout viable platforms, the layout technique needs to develop into versatile and adaptive. In Activity-Centered layout, Geri homosexual and Helene Hembrooke argue that it's time to advance new versions for HCI layout that help not just study and improvement but in addition investigations into the context and motivation of consumer behavior.Gay and Hembrooke study the continued interplay of computers use, layout perform, and layout review, utilizing the thoughts of task concept and similar equipment as a theoretical framework. one of the subject matters they talk about are the reciprocal courting among the instrument and the duty, how actions form the necessities of specific instruments and the way the applying of the instruments starts to reshape the task; differing wishes and expectancies of contributors whilst new expertise is brought, analyzing specifically the combination of instant hand-held units into museums and studying environments; and the impression of the format of the computing area on stream, functionality, and social interplay. homosexual and Hembrooke then observe their findings at the use of know-how in daily contexts to notify destiny HCI layout perform.

Web-Based Concept Mapping In the initial phase of the Handscape project, approximately 115 people participated in the statement-generation stage, and responses were col­ lected from thirty-five museum professionals, eighteen system designers and vendors, and sixty-two museum patrons. Museum professionals in­ cluded science writers, directors of education and digital media, chief cu­ rators, vice presidents, and information officers. Understanding Perspectives 21 Because the initial stage of the process was Internet-based, participants could complete this task from remote locations.

We identified relevant social groups (or stakeholders) and had them state their needs, prioritize them, and cri­ tique prototype scenarios. To illustrate this process, we describe a design project called Handscape in the following sections. The Handscape Study: Using Mobile Technologies to Enhance the Museum Experience Handscape is an ongoing research project (2001-2004) that has been funded by Intel Corporation and managed by the Human-Computer In­ teraction Group at Cornell University and by CIMI, an international consortium of museums, application developers, and national standards organizations.

The developments, tensions, and interrela­ tionships in these systems should be studied in the context of these ac­ commodation processes. As the ecological approach and the process, person, and context model are explored, we describe and account for the transformative power of seemingly ubiquitous artifacts such as language ; and pervasive computing devices.
