Single Vs Dual: Influence of the Number of Displays on User Experience within Virtually Embodied Conversational Systems

Navid Ashrafi, Francesco Vona, Philipp Graf, Philipp Harnisch, Sina Hinzmann, Jan-Niklas Voigt-Antons

TL;DR

The findings showed significantly higher usability and higher pragmatic quality ratings for the single tablet condition, however, some users attribute a higher level of presence to the avatar and prefer it to be placed on a second tablet.

Abstract

The current research evaluates user experience and preference when interacting with a patient-reported outcome measure (PROM) healthcare application displayed on a single tablet in comparison to interaction with the same application distributed across two tablets. We conducted a within-subject user study with 43 participants who engaged with and rated the usability of our system and participated in a post-experiment interview to collect subjective data. Our findings showed significantly higher usability and higher pragmatic quality ratings for the single tablet condition. However, some users attribute a higher level of presence to the avatar and prefer it to be placed on a second tablet.
