This research advocates for exploring the somatosensory system and its incorporation within XR systems, particularly in spatial recognition. This paradigm shift could introduce novel methodologies in XR design that perceive the body as a recipient of sensory stimuli and as an active participant in sensory perception. This could redefine our understanding of somatosensory in XR and contribute to a more holistic approach to multisensory design. Additionally, this study aims to examine the deployment of XR in the evaluation of aircraft interior design. The successful integration of XR technologies could potentially revolutionize the design process by presenting a more immersive and authentic user testing environment. In light of the present deficiency in precise spatial recognition within XR applications, this research could offer fresh insights into optimizing XR use in design, thereby improving spatial perception accuracy and enhancing ergonomics and user experience in real-world applications, such as aircraft interior design.
