### Discussion of Results
#### 5.1.1 Construction and Validation of Seamless Technology Integration Framework  
The seamless technology integration framework developed in this study demonstrated significant benefits in the empirical studies. The System Usability Scale (SUS) evaluations showed a significant improvement, from 77.85 (\(\pm\)2.31) in phase one to 82.15 (\(\pm\)2.15) in phase two (\(p<\) 0.001, [PERSON]'s d = 0.92). These results not only validate the hypothesis that integrating technology into daily objects effectively reduces usage barriers but also extend [PERSON]'s [22] theoretical vision of ubiquitous computing. Particularly noteworthy is the high score of 85.32 achieved in the group activity contexts, further confirming that embedding technology in familiar contexts effectively enhances users' acceptance.  
The six-dimensional design framework proposed in this study demonstrated integrative benefits in practical applications. At the psychological level, the dimensions of life integration, warmth, and emotional connection effectively reduced elderly users' resistance to the technology; at the functional level, the dimensions of intuitiveness, simplicity, and personalization ensured the system's usability. These findings reflect [PERSON]'s [6] affordance theory, confirming that when technological interfaces align with users' natural perceptual patterns, users can operate through intuitive understanding. The research results also support [PERSON]'s [7] application of ecological psychology to human-computer interaction and provide concrete implementation evidence in the field of elderly technology design.  
From a design implementation perspective, this study achieved seamless technology integration at three levels. Firstly, at the physical level, it successfully incorporated capacitive sensing technology into pillows while maintaining their original tactile qualities and appearance. Notably, through innovative fabric structure design and specialized pocket design, it effectively resolved the capacitive displacement issues, improving the sensing accuracy from 75% to 92%. Secondly, at the user experience level, the research results support [PERSON]'s natural mapping principle, with the experimental data showing that the optimization of the system's response time (from 0.47 to 0.17 s) indeed enhanced its operational fluency. Finally, at the emotional connection level, maintaining the product's original emotional value ensured that the addition of technological functions did not affect the existing emotional connections between the users and objects, as reflected in the higher social interaction scores (\(4.4\pm 0.41\)) and expectation performance (\(4.3\pm 0.42\)) in group interaction contexts. The statistical analysis showed that these aspects demonstrated significant improvements over individual usage contexts (\(p<0.001\)), with large effect sizes ([PERSON]'s d > 0.8).  
The research results particularly highlight three key values of the seamless technology framework in elderly technology design. Firstly, the framework provides a systematic design methodology that helps developers to achieve a balance between technical implementation and user needs. Secondly, the integrated design ensures dual benefits, in terms of both functional and emotional aspects. Thirdly, empirical research confirms the framework's practicality, providing concrete design guidelines for future elderly technology product development. These findings not only support [PERSON] et al.'s [15] research on elderly technology acceptance but also validate this innovative design methodology.
