Vestibular Immersion

This chapter explores the mechanisms and technologies that address the challenges in creating convincing vestibular immersion, highlighting the interplay between vestibular perception and motion tracking systems. The vestibular system is responsible for maintaining balance, detecting motion, and orienting the body in space. The vestibular system comprises two primary sensory structures: the semicircular canals and the otolith organs. Sensory conflicts in virtual and augmented reality often arise from discrepancies between what users see and what their vestibular system detects. Achieving vestibular immersion in virtual and augmented reality applications involves replicating the sensations of motion, balance, and spatial orientation to create an experience where users feel as if they are truly present in the simulated environment. Motion tracking is commonly categorized into two types: three degrees of freedom and six degrees of freedom.
