Optimizing Item and Subgroup Configurations for Social-Aware VR Shopping
Summary: Proposes SVGIC, a problem of configuring displayed items and subgroup partitions for social-aware VR group shopping. APX-hard and NP-hard to approximate within 32-ε; a 4-approx CSF-based algorithm; experiments on real VR data and a user study with HTC VIVE show ~30% improvement over baselines.
