Abstract
In conventional media session handoff, flat video feeds or uniform resource locators are transferred between displays, resulting in the loss of active interface overlay states and the underutilization of spatial computing capabilities.
This paper describes a method for spatial media session handoff and volumetric interface decomposition. Line-of-sight directional vectors between a planar display and a head-mounted computing device are confirmed using ultra-wideband ranging. A volumetric state packet—including millisecond-accurate media timecodes, serialized user interface snapshots, and session security tokens—is compiled and transmitted over a local wireless link. Two-dimensional interface overlays are transcoded into distinct three-dimensional spatial panels positioned relative to physical environment boundaries while maintaining primary media playhead synchronization.
Active user interface state overlays are preserved across device handoff without manual credential entry or flat display mirroring.
