MULTIMEDIA TOOLS AND APPLICATIONS
Abstract
Virtual reality (VR) is used in different application fields like health, tourism, or training. Most VR applications for these fields have been built from the ground up without any authoring tool to help the process. This systematic review surveys the existing literature on authoring tools for immersive content and critically analyzes its features and how they are evaluated. It proposes a research agenda with key contribution opportunities for the field. An analysis of the 29 studies that met the eligibility criteria revealed that four records did not present any evaluation regarding the authoring tools' evaluation, and only five records used specialized users to evaluate their authoring tools; all the others used non-specialized users. The most evaluated metrics were usability, effectiveness, efficiency, and satisfaction. The data collected to evaluate the metrics consisted mainly of Likert scales and reported mean opinion score (MOS). However, few records used well-established questionnaires to evaluate those metrics like System Usability Scale, Post-Study System Usability Questionnaire, After-Scenario Questionnaire and Igroup Presence Questionnaire. Additionally, five of the analyzed records included stimuli other than audiovisual. More research is recommended about the usage of ontologies in authoring tools to comprehend the full potential of its usage since none of them had ontologies.

Abstract
User experience can be affected by the amount and intensity of information presented. Four scenarios were developed to assess the insertion of information elements (chronometer and hint system) and tested with 37 users to find out if they affected the user's sense of presence and symptoms of cybersickness. In order to instruct users and using virtual reality using the Unity 3D game engine, we created a virtual world where the user has the role of exploring the environment and looking for mushrooms, and can consult a description about it. For tests with users, the IPQp and SSQ questionnaires were applied. The results indicate that it is possible to create a virtual world with the addition of informational components without significantly disturbing the user experience. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
