目前大多数商业虚拟现实（VR）绘图应用程序都依赖于徒手3D绘图作为其主要的交互范例。然而，额外的第三维度的存在使得准确的徒手绘图具有挑战性。有些系统通过限制或美化用户笔触来解决这个问题，这可能是侵入性的，并且可能限制徒手绘图的表现力。在本文中，我们评估了仅依靠视觉引导来增加整体绘图形状相似性的有效性。我们确定了用户在VR中创建徒手笔画时会犯的一系列常见错误，然后设计了一套视觉指南Smart3DGuides，帮助用户避免这些错误。我们在两项用户研究中评估了Smart3DGuides，我们的结果表明，无约束的视觉指南可以帮助用户更准确地绘制。
Most current commercial Virtual Reality (VR) drawing applications for creativity rely on freehand 3D drawing as their main interaction paradigm. However, the presence of the additional third dimension makes accurate freehand drawing challenging. Some systems address this problem by constraining or beautifying user strokes, which can be intrusive and can limit the expressivity of freehand drawing. In this paper, we evaluate the effectiveness of relying solely on visual guidance to increase overall drawing shape-likeness. We identified a set of common mistakes that users make while creating freehand strokes in VR and then designed a set of visual guides, the Smart3DGuides, which help users avoid these mistakes. We evaluated Smart3DGuides in two user studies, and our results show that non-constraining visual guides help users draw more accurately.
