Evaluating Interaction-Triggered Emotions in People with Dementia

Current User Experience (UX) tools are not applicable for evaluating the UX of people with moderate to severe dementia as communicating about self-reflection is beyond their abilities. Observational Quality of Live (QoL) methods are frequently used in the dementia context, but not designed for formative evaluations. In this paper we present Proxemo, a prototypical approach combining the strengths of methods from both domains. By enabling evaluators to accurately document emotions of people with dementia Proxemo overcomes the problem of UX tools requiring self-report and the vague timeframes of QoL methods. In a preliminary study experienced evaluators from the domains of UX and dementia interacted with the prototype intuitively and were keen on applying it in an evaluation. In future work we will optimize Proxemo for rating emotions of multiple users.
