Abstract. This article addresses the design and implementation of user interaction concepts for smart caring homes. Elderly suffering from age related frailty or chronic diseases, such as chronic obstructive pulmonary disease and mild dementia are the targeted primary users. Their informal and formal caregivers are regarded as secondary users. The current smart home approach to user interaction is either too intrusive or too unobtrusive. This article proposes an alternative that implements both concepts in complementary interaction paradigms, using multiple types of feedback devices.
BACKGROUND
Studies that focus on the acceptance of an electronic health (eHealth) technology generally make use of surveys. However, results of such studies hold little value for a redesign, as they focus only on quantifying end-user appreciation of general factors (eg, perceived usefulness).
OBJECTIVE
We present a method for understanding end-user acceptance of an eHealth technology, early in the development process: The eHealth End-User Walkthrough.
METHODS
During a walkthrough, a participant is guided by using the technology via a scenario, a persona, and a low-fidelity protoype. A participant is questioned about factors that may affect acceptance during and after the demonstration. We show the value of the method via two case studies.
RESULTS
During the case studies, participants commented on whether they intend to use a technology and why they would (not) use its main features. They also provided redesign advice or input for additional functions. Finally, the sessions provide guidance for the generation of business models and implementation plans.
CONCLUSIONS
The eHealth End-User Walkthrough can aid design teams in understanding the acceptance of their eHealth application in a very early stage of the design process. Consequently, it can prevent a mismatch between technology and end-users’ needs, wishes and context.
