With recent advancements leading to significant reductions in the weight and cost of extended reality (XR) glasses, the adoption of XR technology is accelerating. However, the user interfaces of existing XR operating systems face numerous accessibility challenges, including inaccurate distance estimation, the lack of haptic feedback, arm fatigue from prolonged use, and unreliable hand interactions during walking. These issues continue to hinder the widespread practical use of XR technology. To address these challenges, we developed a set of accessibility-enhancing interaction techniques. This includes: spatial reference techniques based on the affordances of users' physical surroundings and their proprioception, upper limb movement optimization techniques utilizing kinesthetic appendages, and interaction techniques for the walking scenario that leverage lower limb and head movements. These innovations enable users to interact with XR interfaces in an easy and effective way.
