AI Technical Summary

Technical Problem

Existing wireless headphone technologies experience transfer latency due to the time required for sending sensor data between headphones and the device, which affects the adaptation of sound based on the user's head position and angle.

Method used

A method of predicting future head movements based on motion data history, using quaternion domain processing to adjust the sound field and compensate for latency, employing filters to reduce noise and enhance prediction accuracy.

Benefits of technology

The method reduces sensor signal noise and improves the listening experience by accurately predicting future head movements, thereby mitigating the impact of Bluetooth latency.
