Combining ethnography and object-orientation for mobile interaction design: Contextual richness and abstract models

Abstract

There has been a lot of interest in ethnography within human-computer interaction over the last two decades, and its relevance within systems development is today beyond question. However, one of the challenges reported is that ethnography generates findings and knowledge with such contextual richness that it can be hard to transfer into system design. In the light of recent years' push for the use of ethnography within the area of mobile human-computer interaction, this challenge has resurfaced and is of renewed importance to the research field. In this article we describe an interdisciplinary combination of ethnography with a structured software engineering method supporting the transition from collected data to design and implementation. We explore this combination through two case studies of mobile system development for supporting distributed work activities within industrial process control. We show that when developing mobile systems ethnographic data is a highly valuable source of input for developing object-oriented models by providing contextual richness, and that in turn, objected-oriented analysis is a highly valuable method for working with ethnographic field data in systems development by supporting the creation of abstract models. Combining the two, we have a method where ethnographic field studies inform core system design.

A Design Process for a Customer Journey Map: A Case Study on Mobile Services

“…Ethnography analyzes human activities in a particular context in the form of verbal descriptions (Hall, ). It has tools such as observational field studies, contextual interviews, diary studies, and the collation of background information and documentation (Hall, ; Kjeldskov & Stage, ). This study used the user diary method to collect users’ daily activities and their pain points.…”

Towards a Method for Mobile Learning Design

“…This design needs to look at the "real needs of instructors and learners" (Alvarez, Alarcon, & Nussbaum, 2011) and at the social aspects that mobile technology was originally intended for to get the most out of mobile learning. In addition it should consider the 'as-lived-experience' of mobile learners (Kjeldskov & Stage, 2012), because in essence learning is deeply social (Burdick & Willis, 2011). However, the determining factor for mobile technologies in learning will be dependent on its adoption by both educators and the learners (Alvarez et al, 2011).…”
