A model for contextual data sharing in smartphone applications

Abstract

Purpose -The purpose of this paper is to introduce a model for identifying, storing, and sharing contextual information across smartphone apps that uses the native device services. We present the idea of using user input and interaction within an app as contextual information; and how each app can identify and store contextual information. Design/methodology/approach -Contexts are modelled as hierarchical objects that can be stored and shared by applications using native mechanisms. A proof-of-concept implementation of the model for the Android platform demonstrates contexts modelled as hierarchical objects stored and shared by applications using native mechanisms. Findings -The model was found to be practically viable by implemented sample apps that share context and through a performance analysis of the system. Practical implications -The contextual data-sharing model enables the creation of smart apps and services without being tied to any vendors cloud services. Originality/value -This paper introduces a new approach for sharing context in smartphone applications that does not require cloud services.
