### Smart Home Subsystem Attribute Analysis Based on the Kano Model
#### 5.2.2 Smart Home Subsystem Attribute Evaluation  
According to the Kano model, specific items of dysfunctional and functional was coded in Table 5. Importance was coded from \"1 = not important at all\" to \"9 = Extremely Important\". Followed [PERSON]'s method [76], discrete and continuous analysis of attribute for smart home subsystems and dysfunction, function, and importance results were shown in Tables 6 and 7, Figures 4 and 5. \begin{table}
\begin{tabular}{c c c} \hline
**Connectivity System** & **Question** & **Answer** \\ \hline Functional & If the smart home has the & (1). I like it that way (2). It must be that way (3). I am neutral \\ form & home appliances system, how & (4). I can live with it that way (5). I dislike it that way \\ \hline Dysfunctional & If the smart home doesn’t have & (1). I like it that way (2). It must be that way (3). I am neutral \\ form & how do you feel? & (4). I can live with it that way (5). I dislike it that way \\ \hline \end{tabular}
