Activities, Context and Ubiquitous Computing

TL;DR

This paper introduces an Activity-Centric Context model for building complex, cognitive, context-aware applications that adapt to user needs and environments by sensing and deriving context automatically.

Contribution

It presents a novel conceptual model of context focused on activities, enabling more sophisticated and responsive context-aware computing systems.

Findings

The Activity-Centric Context model effectively captures complex user activities.

The model supports the development of more attentive and responsive applications.

A detailed example illustrates the practical application of the model.

Abstract

Context and context-awareness provides computing environments with the ability to usefully adapt the services or information they provide. It is the ability to implicitly sense and automatically derive the user needs that separates context-aware applications from traditionally designed applications, and this makes them more attentive, responsive, and aware of their user's identity, and their user's environment. This paper argues that context-aware applications capable of supporting complex, cognitive activities can be built from a model of context called Activity-Centric Context. A conceptual model of Activity-Centric context is presented. The model is illustrated via a detailed example.
