eEVA Data Generation and User Results Analysis Ver 1.0

This document presents the information necessary to gain a good understanding of eEVA, an empathetic embodied virtual agent. Users interact with this health agent via the web, utilizing cameras and microphones to communicate with the avatar. eEVA can then process the responses to record the user’s choices on the interventions. Although the system is presently programmed to give a health assessment for alcohol screening, the foundation of the system is more flexible, and allows different intervention content to be presented to users, and revised by an administrator. The focus of our work, was to provide eEVA with several functions necessary for the revision of content and her interactions, as well as to design her results pages for the alcohol assessments employed as part of the Drinker’s Check-Up (DCU), as she delivers feedback and scores on the various parts of the intervention.
