Design of a Physiologically Based Feedback Loop Using Biosensors for Interactive XR and Spatial Computing Environments

This work investigates the signal characteristics of a physiological response (acute stress) and determines the viability of developing a Virtual Reality (VR) integrated physiologically based real-time feedback loop. This work has possible applications in physiotherapy and patient rehabilitation for long-term conditions including long COVID, persistent pain, and chronic fatigue. Using real-time physiological data, this approach can offer an individualised and immersive therapeutic experience. By synchronizing VR experiences with physiological responses, clinicians can optimise treatment efficacy and facilitate targeted rehabilitation efforts. A design and early prototype were developed to include a feedback loop driven by an ensemble of biosignal signatures, correlating with stress responses, that adjusts dynamic components in the environment. The prototype shows the feasibility of developing a physiologically based XR environment suitable for virtual physiotherapy interventions.
