Abstract
This research develops Presence Stickers, the capacitive sensing module that can be easily affixed to the existing space element surfaces (such as a wall, door, stairs), and daily objects or home furniture (such as a chair, cabinet, table, sofa, etc.). These 30*30 cm Presence Stickers can actively sense peopleÂs physical behaviors and body movements in spaces. From the preliminary analysis of observing the 80-year-old elderly subjectÂs daily activities, the movement trajectory of the ÂMove-Stop pattern is found. There will be a Touch (T) and Touchless (TL) relationship between the body and the space elements or objects. Furthermore, the touchless, or non-contact, intimate relationship can also be divided into two types: 1. The body that ÂPasses by (P) the spatial elements or objects, and 2. The body that ÂStays (S) in front of the object and performs activities. These three types of the intimate relationship between bodies and objects, i.e., T, TL-P, and TL-S, were used as the main sensing conditions to develop the Presence Stickers sensor module. We affixed 8 Presence Stickers on 9 objects in six spaces and finally, the life pattern can be analyzed and the sensors provide the customized intelligent application function for the elderly.
