Summary

An integrated sensing and communication (ISAC) architecture is proposed for real-time avatar control in Extended Reality (XR) over 5G and 6G networks, addressing the limitations of current handheld controllers and cameras. This multimodal system combines 5G MillimeterWave (mmWave) ISAC with surface electromyography (sEMG) signals. 5G mmWave ISAC utilizes existing communication signals, specifically power-per-beam-pair (PPBP) from standard beam management, to derive coarse body-level gestures, achieving 82.2±5.9% average accuracy on unseen users. For fine-grained finger-level interactions, lightweight sEMG sensors capture forearm muscle activity. This combination enables multi-scale gesture recognition, forming a complete XR framework that supports seamless physical action translation to the virtual world.

Key takeaway

For AI Engineers and XR developers designing immersive experiences, this research presents a compelling approach to achieve natural, controller-free avatar control. You should consider integrating 5G mmWave ISAC with sEMG for robust, multi-scale gesture recognition. This method moves beyond traditional HMD and controller limitations, enhancing user immersion and interaction fidelity in future XR applications by translating physical actions seamlessly into the virtual world.
