### System Impact on the Person  
We experimented for 2 weeks with the sensor monitoring system and 2 weeks without the system. We carried out tests in the homes of 50 people between 50 and 70 who live alone. Of these people, 23 were women and 27 were men. Having some vital signs monitored can impact a person's peace of mind by providing information about their overall health. Abnormal readings can indicate underlying health problems, such as high blood pressure, heart disease, respiratory problems or fever, which can cause stress and anxiety. On the other hand, having normal readings can give a person a sense of reassurance and peace of mind. Regular monitoring of these vital signs is important for maintaining good health and detecting potential problems early. Heart rate (HR) or pulse: The heart rate, also known as pulse, is the number of times the heart beats per minute. It is usually measured by counting the number of beats in a minute at the wrist or neck. Figure 3: Logical change of topology through 5 days under each system scheme. Respiratory rate (RR): Respiratory rate is the number of breaths a person takes in a minute. It is usually measured by counting the number of breaths a person takes in one minute. Temperature (T): Body temperature is a measure of the body's ability to produce and get rid of heat. Normal body temperature is about 98.6 \"F (37 \"C). Rapid Eye Movement Sleep (REMS): This is a stage of sleep characterized by quick movements of the eyes and increased brain activity. This stage is also known for vivid dreaming and decreased muscle tone, which prevents physical movement during sleep. REM sleep is an important part of the sleep cycle and typically occurs several times during a night's sleep. We report the REMS analysis through a smartwatch for a person's commercial use and with this we analyze this metric in such a way that we can do it at home and check it every day upon waking up. Based on the analysis of a person's main vital signs, we analyzed their daily monitoring. This study considered healthy people (not high-performance athletes) who were non-smokers and had no cardiac or respiratory conditions. For this experimentation, we consider the measurement daily and at the same time when the person wakes up. This is so that the person is not agitated or prone to worries during the day caused by external factors. Figure 4 shows the behavior of most of the data with and without the monitoring system. We divided the population into men and women because there are physiological differences in heart rate according to gender. Men and women have differences in their anatomy, hormone levels and physical activity patterns, which contribute to variations in heart rate. Men generally have larger hearts and more muscle mass, resulting in a lower resting heart rate. Hormonal differences also play a role, with higher levels of testosterone in men leading to a lower heart rate than in women with higher levels of estrogen. Women also experience fluctuations in hormone levels during their menstrual cycle and pregnancy, which can affect their heart rate. Additionally, women tend to have less physically active lifestyles than men, leading to differences in heart rates between the two sexes. We obtained this information from the sensors because women mainly reported in specific areas of the house. This is accomplished by input from motion sensors and door gyroscopes. Conversely, men are reported to be more active in different areas of the house during the day, which could be associated with more activity. We then found that, apparently, for women, the monitoring system represents a kind of greater peace of mind by 4% when they are under the presence of the monitoring system. Concerning men, this difference is only 2%. For both cases, in the presence of the sensor system, the heart rate numbers decrease for both genders. Figure 4: Heart rate with and without the monitoring system for men and women. Table 4 shows the change or variability a metric can have in the presence or absence of the sensor system.
