HCI Methods and Practices for Audiovisual Systems and Their Potential Contribution to Universal Design for Learning: A Systematic Literature Review

Abstract

Audiovisual production, which was previously mostly investigated by film and television studies, now becomes more comprehensive and can involve aspects of psychology, pedagogy, neuroscience and especially computing. In parallel to this evolution, studies on Universal Access or Universal Design have been expanding their scope for services, technologies and learning processes. This article presents a systematic literature review with the objective of investigating the main uses and applications of Computer Human Interaction (IHC) theories and methods related to the development of audiovisual systems and their possible contributions to Universal Design for Learning (UDL). The review contemplates articles from four databases in the period from 2010 to 2018. All 31 articles are classified by the context of the research problems and solutions proposed using principles of the grounded theory, that is, the codification of data through hierarchical categorization, establishment of relation and creation of central categories. These works are divided into three main groups of problems (user interfaces, theoretical and behavioral bases and system application) and solutions (theories and methods, design and evaluation of interactive systems and case studies). HCI state of the art productions and methods using audiovisual systems, i.e. audio and video, multimedia, hypermedia or even multimodal systems, has revealed a scenario of products, devices and interaction methods that have evolved and become more complex over the years. While not working directly with the Universal Design context, the various solutions present results that can benefit the development of learning support systems.
