A head-wearable apparatus improves user interactions with virtual interface elements in augmented reality (AR) environments. The apparatus tracks hand movements in 3D space, calculating velocity vectors and positions of fingers. For each virtual interface element, it determines a UI-to-finger vector and calculates alignment with the finger's velocity vector. Interaction zones are dynamically adjusted based on this alignment and velocity magnitude. The system evaluates consistency between finger movement and element locations to predict intended targets. Interactions are triggered when fingers enter adjusted zones of predicted targets. This approach reduces erroneous selections and improves interaction accuracy, even for closely-spaced elements. The invention applies to various AR scenarios, enhancing user experiences in applications like gaming and education.

This invention discloses a fast relocalization method based on tight coupling between sparse semantic anchors and inertial sensing, belonging to the fields of augmented reality and computer vision. It constructs a lightweight sparse semantic map by extracting sparse feature points with stable geometric and semantic attributes from the environment as sparse semantic anchors. When device tracking is unstable or lost, inertial navigation and visual matching threads based on sparse anchors are activated in parallel. The core PnP algorithm is used to quickly recover the visual pose, and the method is tightly coupled with inertial data for optimization, ultimately outputting a high-precision, smooth six-DOF pose. This solves the problem of excessively long relocalization time and experience interruption in traditional visual SLAM scenarios with fast motion and weak textures, achieving millisecond-level, user-unnoticed tracking recovery, significantly improving the robustness and user experience of augmented reality systems.
