可延展和有机的用户界面有潜力通过灵活、自由和计算控制的形状和显示，实现全新的交互和表达形式。这项工作特别关注粒子干扰作为一种简单有效的方法，用于灵活的、可改变形状的用户界面，其中材料刚度的程序化控制可以实现触觉反馈、变形、可调的性能和控制增益。我们介绍了一种适用于移动设备的紧凑、低功耗气动干扰系统，以及一种基于液压的新技术，该技术具有快速、无声驱动和光学形状传感。我们通过两种高分辨率形状传感方法，使干扰结构能够感知输入并作为交互设备发挥作用：1)指数匹配的颗粒和流体，以及2)电容和电场传感。我们通过四个动机原型来探索可塑和有机用户界面的设计空间，这些原型突出了干扰在HCI中的潜力，包括桌面、平板电脑和便携式变形移动设备的应用。
Malleable and organic user interfaces have the potential to enable radically new forms of interactions and expressiveness through flexible, free-form and computationally controlled shapes and displays. This work, specifically focuses on particle jamming as a simple, effective method for flexible, shape-changing user interfaces where programmatic control of material stiffness enables haptic feedback, deformation, tunable affordances and control gain. We introduce a compact, low-power pneumatic jamming system suitable for mobile devices, and a new hydraulic-based technique with fast, silent actuation and optical shape sensing. We enable jamming structures to sense input and function as interaction devices through two contributed methods for high-resolution shape sensing using: 1) index-matched particles and fluids, and 2) capacitive and electric field sensing. We explore the design space of malleable and organic user interfaces enabled by jamming through four motivational prototypes that highlight jamming's potential in HCI, including applications for tabletops, tablets and for portable shape-changing mobile devices.
