Augmented rotations in virtual reality for users with a reduced range of head movement


Introduction: A large body of research in the field of virtual reality is focused on making user interfaces more natural and intuitive by leveraging natural body movements to explore a virtual environment. For example, head-tracked user interfaces allow users to naturally look around a virtual space by moving their head. However, such approaches may not be appropriate for users with temporary or permanent limitations of their head movement.

Methods: In this paper, we present techniques that allow these users to get virtual benefits from a reduced range of physical movements. Specifically, we describe two techniques that augment virtual rotations relative to physical movement thresholds.

Results: We describe how each of the two techniques can be implemented with either a head tracker or an eye tracker, e.g. in cases when no physical head rotations are possible.

Conclusions: We discuss their differences and limitations and we provide guidelines for the practical use of such augmented user interfaces.

As an experimental (neuro)psychologist I like to understand more about how we and AI-driven co-actors are interacting in a digital world. Data-Science, User-Experience Research and understanding social cognition with robots and virtual partners are my main topics. Understanding processes and optimization is my matter of the heart - UX and Human-Centered-Design is a universal approach to every challenge in our life.
