Voz da aventura: histórias interativas para o sistema Amazon Alexa

Abstract

This Final Course Project (TCC) presents the development of a prototype application for the Amazon Alexa virtual assistant, named Voz da Aventura, focused on interactive story narration. The project, of an experimental nature, aimed to investigate the technical feasibility and the narrative possibilities provided by voice interfaces, exploring the architecture and resources of the Alexa Skills Kit (ASK). The adopted methodology included the study of conversational design, dialogue flow modeling, and state management. The solution is composed of two distinct and integrated applications: a Backoffice for content management and an Alexa Skill as the voice interface for the end user. Technical details regarding the technologies used in the development of the Backoffice (Node.js, Express, Postgres, TypeORM) and the Alexa Skill (ask-sdk-core, ask-sdk-model, Axios) are presented. Additionally, usability tests were conducted with users using the System Usability Scale (SUS), whose results indicated a positive perception regarding the application's usability. Overall, the results demonstrate the feasibility of the proposed solution.
