ZeroTouch（ZT）是一种独特的光学传感技术和架构，允许在受限的二维平面内精确感测手、手指和其他物体。ZeroTouch提供80 Hz的跟踪，最多30个并发触摸点。与LCD的集成是微不足道的。虽然设计用于多点触摸感应，但ZT支持其他新模式，例如笔+触摸和自由空间交互。在本文中，我们的背景下ZT创新与其他平板传感技术的审查。我们提出了ZT背后的模块化传感架构，并研究了ZT传感的早期多种用途。
ZeroTouch (ZT) is a unique optical sensing technique and architecture that allows precision sensing of hands, fingers, and other objects within a constrained 2-dimensional plane. ZeroTouch provides tracking at 80 Hz, and up to 30 concurrent touch points. Integration with LCDs is trivial. While designed for multi-touch sensing, ZT enables other new modalities, such as pen+touch and free-air interaction. In this paper, we contextualize ZT innovations with a review of other flat-panel sensing technologies. We present the modular sensing architecture behind ZT, and examine early diverse uses of ZT sensing.
