@inproceedings{ZhangWM26_LyreOfUr_XRSalento, abstract = {We present a virtual reality (VR) system that makes the Golden Lyre of Ur (c. 2500 BCE) playable through optical hand tracking, coupling a Finite Difference Time Domain (FDTD) string model with Extended Position-Based Dynamics (XPBD) visual deformation. Continuous collision detection and force clamping ensure numerical stability under unconstrained multi-string gestures while preserving musically expressive dynamic response. To compensate for the absence of haptic feedback inherent to hand tracking, we propose a Visual Haptic Surrogate (VHS) framework that organizes visual feedback into three layers addressing pre-contact, contact-onset, and post-contact haptic information gaps. An evaluation with five participants with musical backgrounds provides preliminary evidence that plucking and muting are achievable without haptic resistance and that the pitch control is feasible, though precise interaction remains difficult. A \$\$2\backslashtimes 2\$\$2×2within-subject comparison of four visual conditions suggests physics-driven string deformation as the highest-priority surrogate layer, yielding transferable design guidance for hand-tracked virtual reality musical instruments (VRMIs).}, address = {Cham}, author = {Zhang, Yaozhong and Shehata, Dahlia and Wei{\ss}, Christof and von Mammen, Sebastian}, booktitle = {Extended Reality}, editor = {De Paolis, Lucio Tommaso and Arpaia, Pasquale and Sacco, Marco}, keywords = {myown}, pages = {503–523}, publisher = {Springer}, series = {Lecture Notes in Computer Science (LNCS)}, title = {Resurrecting the Golden Lyre of Ur: A Physics-Based Virtual Instrument Using Visual Haptic Surrogates for Hand-Tracked Interaction}, volume = 16838, year = 2026 }
