### Smart Home Subsystem Attribute Analysis Based on the Kano Model
#### 5.2.2 Smart Home Subsystem Attribute Evaluation
From Table 7 and Figure 5, we can see that most of the attributes of the thirty smart home subsystems belong to the \"one-dimensional \" category, occupying 73.3% of all the subsystem features, and the importance test result in Figure 4 indicates that all the features generally stays a high importance value, which means that the majority of the smart home connectivity subsystems we have proposed cater to Chinese users preference and expectation, and the more the system functions have, the higher the satisfaction of new future elderly to a smart home is. Among them, there are two \"M\" connectivity subsystems, namely \"Home appliance system\", and \"Emergency response system\", which shows that

Figure 5: The attribute distribution in the Kano Model. for the future elderly, smart home equipment that can help them live more independently and the emergency response devices which can guarantee the safety of their lives and property are essential elements of the home environment for the aging group. There are two \"A\" connectivity subsystems, namely \"Family connectivity\" and \"Re-employment and society contribution\". \"Family connectivity\" is classified as \"A\", indicating that for the future Chinese elderly group, family relationship and connectivity is what they are very eager for. This aspect reflects the current status of Chinese elderly life, that is, many of them may live a lonely life or maybe in the status of loneliness and depression because of family members, children, or relatives separation, they are eager for social and communication. On the other hand, it also shows that a smart home can greatly improve elderly well-being and satisfaction if the design and development could make breakthroughs and actions in strengthening family connectivity. \"Re-employment and society contribution\" is classified as \"A\". It reflects that, in the future, Chinese elderly people still have a strong desire to have a re-employment life and make contributions to society. Therefore, the services and products of a future smart home can also consider the development in this regard. There are four \"I\" categories, namely \"Smart party system\", \"pet connectivity\", \"Artificial Intelligence connectivity\", and \"Virtual accomplishment\", where \"Smart party system\" shows that Chinese people have few customs of holding party or gathering with their family and friends at home, thus they show low interests in home party mode, this is probably the difference between Eastern and Western cultures; \"pet connectivity\" shows that there is a considerable number of the population in China, at present, do not feed pets, so when they become older, they are not very concerned about this smart home subsystem; \"Artificial intelligence connectivity\" shows that the current Chinese users' acceptance of artificial intelligence products stays low, and it is somehow difficult for them to accept the situation that they are surrounded or cared by robots or machine when they become older; \"Virtual accomplishment\" part shows that the majority of the current Chinese group, after they get older, still yarn for a sense of accomplishment in real life, and they do not have high expectations for the virtual achievement in the Internet or digital games. The above four \"I\" are the average profiles of all collecting responses in the study, but we do not rule out the possibility that these subsystems are loved or expected by some certain population groups. Meanwhile, customers' consumption behavior and acceptance are variable. With the development of technology and the maturity of the market, the current differentiations may become attractive and one-dimension attributes in the future, so here we do not exclude their possibility of future development. To sum up, the thirty smart home subsystems proposed in this article are generally in line with the user's expectations for the future smart home, and the all-round happiness smart home system elements have been clarified for Chinese future elders.
