触摸期间的通信提供了人类与环境智能之间的无缝和自然的交互方式。将无线传输与触摸检测耦合的当前技术遭受选择性和安全性的问题，即，他们无法确保仅通过直接接触而不是通过近距离接触进行沟通。我们介绍BodyWire-HCI，它利用人体作为有线通信信道，以实现人机交互，这是第一次，在触摸过程中严格展示选择性和物理安全的通信。通过利用一种新颖的低频准静电人体通信（EQS-HBC）技术来最小化从身体泄漏出的信号，该技术在发射器和接收器之间存在通过人体的导电通信路径时严格地实现交互。设计技术，如电容性终端和电压模式操作，用于最大限度地减少人体通道损失，在低频工作，使EQS-HBC。这些演示突出了BodyWire-HCI在为各种应用场景启用新的人机交互模式方面的影响，例如安全认证（例如，打开门和配对智能设备）和信息交换（例如，支付、图像、医疗数据和个人档案传输）（https：www.youtube.com/watch? v=Uwrig2XQIH8）。
Communication during touch provides a seamless and natural way of interaction between humans and ambient intelligence. Current techniques that couple wireless transmission with touch detection suffer from the problem of selectivity and security, i.e., they cannot ensure communication only through direct touch and not through close proximity. We presentBodyWire-HCI, which utilizes the human body as a wire-like communication channel, to enable human–computer interaction, that for the first time, demonstrates selective and physically secure communication strictly during touch. The signal leakage out of the body is minimized by utilizing a novel, low frequency Electro-QuasiStatic Human Body Communication (EQS-HBC) technique that enables interaction strictly when there is a conductive communication path between the transmitter and receiver through the human body. Design techniques such as capacitive termination and voltage mode operation are used to minimize the human body channel loss to operate at low frequencies and enable EQS-HBC. The demonstrations highlight the impact ofBodyWire-HCIin enabling new human–machine interaction modalities for variety of application scenarios such as secure authentication (e.g., opening a door and pairing a smart device) and information exchange (e.g., payment, image, medical data, and personal profile transfer) through touch (https://www.youtube.com/watch?v=Uwrig2XQIH8).
