AI Technical Summary

Technical Problem

In multi-user environments, existing smart ring systems struggle to automatically and quickly cluster users, identify paired rings, and distinguish between left and right hands, especially when no manual configuration by the user is required.

Method used

Using multimodal fusion technology, the azimuth, distance, and historical trajectory of the ring are collected. Clustering is performed using shoulder width geometric constraints, posture consistency, and micro-motion synchronization. Combined with gyroscope angular velocity and human midline position scores, a greedy strategy and temporal smoothing algorithm are used to determine whether the ring is left or right.

Benefits of technology

It enables accurate identification of paired rings belonging to the same user without manual intervention, improving the automation and accuracy of networking, and extending battery life through low-power mode, providing continuous and reliable left and right hand position tags.

Abstract

The present application relates to the technical field of human-computer interaction, specifically to a ring pairing and left-right hand determination method and system based on multiple users, and a medium, comprising: first, collecting the azimuth angle, distance and historical trajectory of multiple rings, and clustering them into different user clusters; in the cluster, fusing shoulder width geometric constraints, posture consistency, micro-motion synchronization and historical prior, calculating the pairing score and identifying the paired rings using the greedy strategy; then, by statistically analyzing the rotation bias of the horizontal projection of the gyroscope angular velocity, combining the spatial position score of the ring relative to the body centerline and the historical consistency, calculating the determination score to distinguish the left and right hands. A steady-state mode and an event-driven wake-up mechanism are also introduced to balance power consumption. The present application realizes automatic ring pairing and accurate left-right hand determination through multi-modal fusion.
