Evaluating subjective user experience of multimodal systems

LOCATION: Ernst-Reuter-Platz 7, 20th Floor, Auditorium 1

SPEAKER: Tuuli Keskinen

AFFILIATION: School of Information Sciences, University of Tampere, Finland

ABSTRACT:

Measuring user experience reliably is extremely challenging as the experience is always subjective. Not only are situations experienced and questions interpreted differently but the personal scales of users are different too. Therefore measuring and comparing subjective user experiences is hard, and drawing comprehensive conclusions even more difficult. As a result, several methods for measuring user experience have been developed to fit different contexts and research areas.

However, only few (if any) methods have been developed specifically for evaluating multimodal systems. As multimodality is strongly part of our every-day life there is a genuine need for a user evaluation method, or methods, which truly take into account the special characteristics of multimodality. My research aims at finding out what are these special characteristics, if there are any, and how can subjective user experience be measured taking into account modalities, context and user group. The ultimate goal of my doctoral research is to provide guidelines for measuring subjective user experience of multimodal systems.

In my presentation, I will give an overview of my research and its current state. I will also present several evaluation cases, including used methodology, collected data and key findings.
