Arm Patents Method to Reduce XR Motion Sickness Using Ultrasound

AI-summarised brief · reviewed before publication

Arm, a SoftBank subsidiary and leading semiconductor designer, has been granted a US patent for a method to minimize motion sickness in extended reality headsets. Filed in July 2023 and granted in June 2026, the patent describes a head-mounted system that analyzes visual motion in displayed images. When visual movement conflicts with the wearer’s physical balance, the system triggers ultrasonic transducers to stimulate the vestibular system. This low-intensity focused ultrasound aims to align the user’s sense of balance with virtual motion, reducing dizziness. The technology uses arrays of transducers, potentially employing beamforming to target specific inner-ear regions. Beyond physical stimulation, the system can adjust visual content by fading images, adding vignettes, or reducing motion. It also incorporates user pose data and sensor signals for adaptive comfort management. This approach represents a hardware-software integration strategy to address the sensory mismatch causing XR discomfort, leveraging Arm’s foundational role in mobile and XR processor architectures to enhance user experience through precise vestibular control.

💡 Why It Matters

  • · Vestibular stimulation offers a direct physiological solution to the sensory disconnect that currently limits widespread XR adoption.
  • · By addressing the root cause of motion sickness rather than just masking symptoms, this technology could unlock longer, more immersive sessions for mainstream consumers.
