Abstract

Refrigerators are commonly used by multiple users in the home and office. However, expired food is sometimes left in the refrigerator, and users may eat food belonging to others since food is often arranged in the refrigerator in a disorderly manner. This happens because food is not organized by owner. If food can be linked with its owner, users will not eat food belonging to others, and food in the refrigerator will be consumed prior to expiration by informing the owner of the expiration date. The simplest way to link food with its owner is to input the name of the owner manually every time he or she puts food in the refrigerator, which, however, is tedious and impractical. We propose a method that identifies who put food in the refrigerator by using pressure sensors, an accelerometer, and a gyroscope attached to the refrigerator door. The method analyzes the motions of opening/closing a refrigerator door and the pressure distribution of gripping the door-handle. In the future, we aim to link food with its owner. From the experiment, we confirmed that the method achieves 90.3% accuracy in user identification for a group of four.
一种基于冰箱门开/关特征的用户识别方法
冰箱通常由家庭和办公室的多个用户使用。然而,过期的食物有时会被留在冰箱里,由于冰箱里的食物经常被凌乱地摆放,使用者可能会吃到属于别人的食物。这是因为食物不是由主人组织的。如果食物可以和主人联系在一起,使用者就不会吃属于别人的食物,冰箱里的食物也会通过告知主人保质期提前食用。将食物与主人联系起来的最简单的方法是每次主人把食物放进冰箱时手动输入主人的名字,但这既繁琐又不切实际。我们提出了一种方法,通过使用压力传感器、加速度计和附着在冰箱门上的陀螺仪来识别是谁把食物放进了冰箱。该方法分析了冰箱门的开/关运动和握门把手的压力分布。未来,我们的目标是将食物与主人联系起来。从实验中,我们证实了该方法在四人组的用户识别中达到了90.3%的准确率。
