MorphPatch系统通过表面近似和视触觉错觉，解决VR形状显示器分辨率有限导致的物理与虚拟表面不对齐问题，提升交互性能，效果优于空中和平板类交互。
AI 中文摘要
虚拟现实中的表面交互通过物理支撑和触觉反馈提升输入性能，但当前形状显示器受限于有限的分辨率，可能导致物理表面与虚拟表面不对齐，降低可用性和用户体验。我们提出MorphPatch系统，可实现动态形状显示器与虚拟表面的实时对齐，采用基于有向距离场（Signed Distance Field）的表面近似流程，为多种几何结构找到可行的对齐方案；对于剩余偏差，结合笔重定向技术与视触觉错觉，从感知层面补偿不对齐问题。三项评估表明，其几何对齐效果得到改善，重定向阈值处于可接受范围，且在控制、表面引导和建模结果方面优于空中交互和平板类交互。
英文摘要
On-surface interaction in Virtual Reality improves input performance through physical support and tactile feedback, but current shape displays are constrained by limited resolution. This can misalign physical and virtual surfaces, degrading usability and user experience. We present MorphPatch, a system that enables real-time alignment between a dynamic shape display and virtual surfaces. MorphPatch uses a Signed Distance Field-based surface approximation pipeline to find practical alignments for diverse geometries. For residual discrepancies, MorphPatch incorporates pen redirection with visuo-haptic illusion to perceptually compensate for misalignment. Three evaluations show improved geometric alignment, tolerable redirection thresholds, and better control, surface guidance, and modeling results over mid-air and tablet-like interaction.
