我们提出了一种新的室内项目发现系统使用射频识别（RFID）的无源标签附着在各种物品，家具和墙壁。所提出的系统通过指示从用户的位置到目标物品的RFID标签的估计距离来帮助用户找到丢失的物品。到目标的距离通过使用用户附近的检测到的标签及其检测历史来估计。我们的系统是低成本的，因为该系统使用无源RFID标签，没有电池，它是没有必要记录的对象和每个标签的位置是附加到手动。该系统具有广泛的标签可检测的区域，因为该系统可以通过使用附近的标签彼此的伪距离来估计长距离。我们模拟并证实，我们的算法计算的伪距离可以充分接近真实的距离后，足够数量的RFID扫描。我们还在实际房间中进行了用户研究，并证实我们的系统减少了寻找目标的时间，定量的物理运动和主观工作量。
We propose a novel indoor item-finding system using radio frequency identification (RFID) passive tags attached to various items, furniture, and walls. The proposed system assists the user in finding a missing item by indicating the estimated distance from the user’s location to the target item’s RFID tag. The distance to the target is estimated by using detected tags near the user, and their detection history. Our system is low cost because the system uses passive RFID tags without battery and it is not necessary to record the object and the position every tag is attached to manually. The system has wide range of tag-detectable areas because the system can estimate the long distance by using the pseudo distance of nearby tags to each other. We simulated and confirmed that our algorithm for calculating the pseudo distance could adequately approximate the real distance after a sufficient number of RFID scans. We also conducted a user study in an actual room and confirmed that our system reduced the amount of time to find the target, the quantitative physical movement, and the subjective workload.
