Figure 6. A simple schematic of a smart apartment for elderly care based on different ambient sensors. Pressure sensors are applied to detect the presence of residents on chairs, couches, or in bed. Vibration sensors placed on the floor, motion sensors installed on walls or ceilings, and contact sensors integrated into door handles or kitchen worktops are used to monitor different types of activity (e.g., movements within the apartment, stove use, use of water, opening of cabinets, etc.). Most commonly, the sensors are based on infrared or audio-video technologies. Data of specific activities are collected continuously and wirelessly transmitted to the caregiver of a user through a base station. Then, the collected data are interpreted to analyze trends to detect changes in daily activities and health status. Redrawn with permission^[47].
