Cross-platform service user experience

Abstract

Many web-based services utilize both desktop and mobile terminals in delivering content and functionality to their users. In terms of user experience (UX), the overall chain of interactions, including mobile and non-mobile settings, becomes a central design target. The aim of this study was to investigate, what are the key elements of user experience associated with these, cross-platform interactions. This paper presents the findings from a four week long field study with three web-based cross-platform services. During the study, participants used the services on both their PCs and mobile devices. Diaries and interviews were used for gathering users' experiences with the services. Based on our findings and reflection with related work, we argue that central elements of cross-platform service UX include fit for cross-contextual activities, flow of interactions and content, and perceived service coherence. We propose an initial conceptual framework of cross-platform user experience. The framework can be used to guide the design of cross-platform web services, as it draws attention to elements of user experience that are essentially influenced by the characteristics of cross-platform settings.
