Abstract
We present FlexiBend, a shape-aware strip for sensing deformables, which is made by a dense linear array of strain gauges for shape sensing. With its self-sensing nature, FlexiBend can be easily installed into deformables. After installation, FlexiBend can simultaneously sense user inputs on different parts of a fabrication, or even capture the geometry of a deformable fabrication. Furthermore, by enabling advanced features, such as shape-retaining property, display capability, and motion sensing on FlexiBend, user can also use FlexiBend as a tangible input device. In this thesis, we describe the hardware setup of this shape-aware strip sensor and the deformation reconstruction algorithm for shape sensing. An evaluation shows our prototype is capable of reconstructing complex deformations accurately. We also detail using FlexiBend to detect deformation for flexible models and, with the widget design, for multi-part deformables. We further discuss the potential use for FlexiBend serving as a tangible input device.
