我们提出了iSoft，一个单一的体积软传感器，能够感测实时连续接触和单向拉伸。我们提出了一种低成本和简单的方法来制造这种压阻式的基于软传感器的即时交互。我们采用电阻抗断层成像（EIT）技术来估计指尖接触引起的传感器上的电阻分布的变化。为了补偿弹性体的回弹弹性并实现实时连续接触感测，我们对EIT应用动态基线更新。基线更新由指尖接触和移动检测触发。此外，我们使用基于模型的方法支持单向拉伸感测，该方法与连续接触感测分开工作。我们还为用户提供软件工具包，用于设计和部署带有定制传感器的个性化界面。通过一系列的实验和评估，我们验证了接触和拉伸传感的性能。通过示例应用程序，我们展示了iSoft支持的各种示例。
We present iSoft, a single volume soft sensor capable of sensing real-time continuous contact and unidirectional stretching. We propose a low-cost and an easy way to fabricate such piezoresistive elastomer-based soft sensors for instant interactions. We employ an electrical impedance tomography (EIT) technique to estimate changes of resistance distribution on the sensor caused by fingertip contact. To compensate for the rebound elasticity of the elastomer and achieve real-time continuous contact sensing, we apply a dynamic baseline update for EIT. The baseline updates are triggered by fingertip contact and movement detections. Further, we support unidirectional stretching sensing using a model-based approach which works separately with continuous contact sensing. We also provide a software toolkit for users to design and deploy personalized interfaces with customized sensors. Through a series of experiments and evaluations, we validate the performance of contact and stretching sensing. Through example applications, we show the variety of examples enabled by iSoft.
