Abstract
Context is not simply the state of a predefined environment with a fixed set of interaction resources. It's part of a process of interacting with an ever-changing environment composed of reconfigurable, migratory, distributed, and multiscale resources.

The notion of context in "Information Interaction in Context"
IIiX '10: Proceedings of the third symposium on Information interaction in contextAs a process, information interaction is (fairly) well defined; considerable amount of research is devoted to the topic in various areas, particularly in human information behavior and human-computer interaction. In contrast the notion of "context" in ...
Wearables as Context for Guiard-abiding Bimanual Touch
UIST '16: Proceedings of the 29th Annual Symposium on User Interface Software and TechnologyWe explore the contextual details afforded by wearable devices to support multi-user, direct-touch interaction on electronic whiteboards in a way that-unlike previous work-can be fully consistent with natural bimanual-asymmetric interaction as set forth ...

This article is from an issue of Communications of the ACM on disappearing computers. The issue presents perspectives on technologies, and models for ubiquitous computing. This article focuses on the importance of context, and context-aware computing, in the adaptation of ubiquitous computing. Pervasive or ubiquitous computing is a model of the future evolution of information technologies. In this model, devices, services, and resources are intelligent enough to discover one another, to provide new and useful services. The context captures and models interaction between all of the entities and actors involved in providing a service. The authors use examples to illustrate the construction of a context in different situations, and to show that, in realms of ubiquitous computing, it is not possible to specify the context in advance. The authors then present a context-based framework, and practical issues related to the adaptation and development of context-based computing. The authors successfully present the importance of context and context-aware computing in the adaptation of ubiquitous computing, but readers looking for detail will have to follow up on the references cited in the article.
