A conversational agent that evaluates user experience in a virtual reality game

Abstract

[en] In the last few years, both chatbots and Virtual Reality games have become a hot topic of discussion. On the one hand, chatbots have been used in recent years, especially for customer service, and on the other hand, VR is being promoted thanks to the commitment of large companies such as Facebook and also thanks to lower equipment costs. However, there has been little discussion on the use of the conversational agent in Virtual Reality games to gather user opinions. The main objective of this project focuses on the creation of a conversational agent, capable of interacting with the user through voice and text, and then integrate it into a Virtual Reality game to evaluate user experience in that immersive environment. Specifically, to pave the way of using conversational interaction in a Virtual Reality environment to improve the efficacy of the evaluation process. We design and create a survey agent using Rasa open source platform. In order to evaluate UX, we use the Game Experience Questionnaire. Finally, we integrate the Rasa agent into a game scene in Unity that works in Virtual Reality environment.
