我们介绍TIMMi，一种用于移动的交互的纺织输入设备。TIMMi佩戴在食指上，以提供多模态感测输入隐喻。原型是在单层纺织品上制造的，其中导电硅橡胶被涂上油漆，导电线被缝合。感应区由三个等距的点和一条单独的宽线组成。应变和压力值分别通过分压器从线和三个点中提取。进行回归分析以对传感值与手指压力和弯曲之间的关系进行建模。应用多级阈值来捕获不同水平的手指弯曲和压力。实现时间位置跟踪算法以捕获滑动手势。在这项初步研究中，我们展示了TIMMi作为一个手指佩戴的输入设备，有两个应用程序：控制音乐播放器和与智能眼镜交互。
We introduce TIMMi, a textile input device for mobile interactions. TIMMi is worn on the index finger to provide a multimodal sensing input metaphor. The prototype is fabricated on a single layer of textile where the conductive silicone rubber is painted and the conductive threads are stitched. The sensing area comprises of three equally spaced dots and a separate wide line. Strain and pressure values are extracted from the line and three dots, respectively via voltage dividers. Regression analysis is performed to model the relationship between sensing values and finger pressure and bending. A multi-level thresholding is applied to capture different levels of finger bending and pressure. A temporal position tracking algorithm is implemented to capture the swipe gesture. In this preliminary study, we demonstrate TIMMi as a finger-worn input device with two applications: controlling music player and interacting with smartglasses.
