OverAir specializes in proximity technologies using Near Field Communication (NFC). NFC is a new wireless technology that enables data transmission between two objects when they are within inches of each other. Smartphones & tablets enabled with NFC can exchange data with other NFC devices, or read information from smart tags embedded in posters, stickers and other products. Despite its increasing popularity, legacy devices and non-smartphone devices such as TV monitors are not equipped with NFC transceivers. This limits the applicability of NFC-based proximity solutions. To overcome this barrier, OverAir has identified acoustic communication as an alternative to NFC due to the ubiquity of speakers and microphones in consumer devices. The main objective of this project is thus, to develop a robust acoustic-based proximity detection technique that can interface with OverAir's existing solutions for retailers and conventions. The researcher will address issues including, limitation of speakers and microphone on commodity devices, robustness to ambient noise, coexistence of multiple devices in the vicinity, and prevention of eavesdropping in close collaboration with OverAir.

OverAir专注于使用近场通信（NFC）的近距离技术。NFC是一种新的无线技术，当两个物体相距不到几英寸时，它可以在两个物体之间进行数据传输。支持NFC的智能手机和平板电脑可以与其他NFC设备交换数据，或从嵌入在海报、贴纸和其他产品中的智能标签中读取信息。尽管NFC越来越受欢迎，但传统设备和非智能手机设备（如电视监视器）并未配备NFC收发器。这限制了基于NFC的邻近解决方案的适用性。为了克服这一障碍，OverAir已经将声学通信确定为NFC的替代方案，因为扬声器和麦克风在消费者设备中无处不在。因此，该项目的主要目标是开发一种强大的基于声学的接近检测技术，该技术可以与OverAir现有的零售商和会议解决方案相结合。研究人员将解决问题 包括，限制商用设备上的扬声器和麦克风、对环境噪声的鲁棒性、附近多个设备的共存以及与OverAir密切合作防止窃听。
