非接触式集成电路(IC)卡，如员工身份证和预付卡，被广泛使用。然而，非接触式IC卡仅用于“暂缓”操作。在这里，我们开发了AccelTag，这是一种配备了加速度传感器和液晶显示器(LCD)的非接触式IC卡；因此，我们扩展了非接触式IC卡的功能。AccelTag采用高功能射频识别(RFID)技术，无需电池即可驱动加速度传感器和LCD。AccelTag支持手势操作，如滑动和翻转，并接受方向作为输入。我们创建了一个AccelTag的原型，并研究了它的电特性和手势识别的准确性。结果表明，AccelTag可以在距离阅读器3~15 cm的范围内使用，对滑动和翻转手势的识别准确率平均为65.8%，对感应卡定位的准确率平均为99.2%，对卡片方向的识别准确率平均为83.4%。
Contactless integrated circuit (IC) cards, such as employee ID and prepaid cards, are widely used. However, the contactless IC card is only used for ‘hold over’ operations. Here, we develop AccelTag, a contactless IC card equipped with an acceleration sensor and a liquid crystal display (LCD); we thus extend the functionality of contactless IC cards. AccelTag employs high-function radiofrequency identification (RFID) technology, driving the acceleration sensor and the LCD without a battery. AccelTag supports gestural operations such asslideandflip, and also acceptsorientationas an input. We created a prototype of AccelTag and investigated its electrical characteristics and gesture recognition accuracy. The results showed that AccelTag can be used in the range of 3 cm to 15 cm from the reader and that the accuracy of recognizing the slide and flip gesture, and sensing card orientation was 65.8%, 99.2%, and 83.4% accuracy on average, respectively.
