Disruptive Approaches for Subtitling in Immersive Environments

Abstract

The Immersive Accessibility Project (ImAc) explores how accessibility services can be integrated with 360o video as well as new methods for enabling universal access to immersive content. ImAc is focused on inclusivity and addresses the needs of all users, including those with sensory or learning disabilities, of all ages and considers language and user preferences. The project focuses on moving away from the constraints of existing technologies and explores new methods for creating a personal experience for each consumer. It is not good enough to simply retrofit subtitles into immersive content: this paper attempts to disrupt the industry with new and often controversial methods. This paper provides an overview of the ImAc project and proposes guiding methods for subtitling in immersive environments. We discuss the current state-of-the-art for subtitling in immersive environments and the rendering of subtitles in the user interface within the ImAc project. We then discuss new experimental rendering modes that have been implemented including a responsive subtitle approach, which dynamically re-blocks subtitles to fit the available space and explore alternative rendering techniques where the subtitles are attached to the scene.
