在虚拟现实 (VR) 中抓住物体时能够感受到物体形状的感觉增强了临场感和物体操纵的便利性。尽管大多数先前的工作都集中在手指上的力反馈，但抓取 3D 形状的触觉模拟需要使用整只手的触摸感。因此，我们提出了掌上弹出道具（PuPoP），这是一种戴在手掌上的轻量级气动形状代理接口，可以弹出几个带有预定义原始形状的气囊以供抓握。当用户的手遇到虚拟物体时，通过气泵将合适形状的气囊充气以供抓握；当物体不再发挥作用时，安全气囊就会泄气。由于PuPoP是物理道具，因此它可以提供充分的触觉，增强VR物体操作的真实感。在本文中，我们首先探讨了具有多种形状结构的 PuPoP 的设计和实现。然后我们进行了两项用户研究以进一步了解其适用性。第一项研究表明，当发生冲突时，视觉感觉往往会主导触觉感觉，从而允许具有固定尺寸的道具代表多个具有相似尺寸的虚拟物体。第二项研究比较了 PuPoP 与控制器以及两种 VR 应用中的徒手操作。结果表明，当用户根据虚拟对象的形状握住动态变化的 PuPoP 时，可以增强乐趣和真实感。我们相信 PuPoP 是一种在 VR 中传达触觉形状的简单而有效的方法。
The sensation of being able to feel the shape of an object when grasping it in Virtual Reality (VR) enhances a sense of presence and the ease of object manipulation. Though most prior works focus on force feedback on fingers, the haptic emulation of grasping a 3D shape requires the sensation of touch using the entire hand. Hence, we present Pop-up Prop on Palm (PuPoP), a light-weight pneumatic shape-proxy interface worn on the palm that pops several airbags up with predefined primitive shapes for grasping. When a user's hand encounters a virtual object, an airbag of appropriate shape, ready for grasping, is inflated by way of the use of air pumps; the airbag then deflates when the object is no longer in play. Since PuPoP is a physical prop, it can provide the full sensation of touch to enhance the sense of realism for VR object manipulation. For this paper, we first explored the design and implementation of PuPoP with multiple shape structures. We then conducted two user studies to further understand its applicability. The first study shows that, when in conflict, visual sensation tends to dominate over touch sensation, allowing a prop with a fixed size to represent multiple virtual objects with similar sizes. The second study compares PuPoP with controllers and free-hand manipulation in two VR applications. The results suggest that utilization of dynamically-changing PuPoP, when grasped by users in line with the shapes of virtual objects, enhances enjoyment and realism. We believe that PuPoP is a simple yet effective way to convey haptic shapes in VR.
