#### 4.1.2 Development Results for Design Framework  
Based on the theoretical knowledge gained from the literature analysis, this study developed an integrated design framework addressing both psychological and functional aspects. As shown in Figure 1, the research results indicate that successful elderly-centered technology product design must simultaneously consider six key dimensions. \begin{table}

Table 1: Summary of research methods and approaches. A. Psychological design elements:  
Life integration dimension:  
Embeds technology within daily life;  
Emphasizes interaction modes based on living context;  
Research shows that developing interaction modes from daily behavioral contexts increases familiarity and promotes elderly users' affinity for technological interactive products. Warmth dimension:  
Utilizes familiar objects from daily life as interaction carriers;  
Maintains the original soft tactile qualities in design;  
Research confirms that when interactive design carriers are presented as familiar daily objects and maintain the original material properties, particularly those conveying warmth, it helps to reduce elderly users' fear of technological products. Emotional dimension:  
Centers on intergenerational care;  
Designs interaction methods that promote emotional exchange;  
Research results indicate that interactive technology products facilitating emotional expression or enhancing emotional exchange help to address elderly users' psychological loneliness and more readily generate strong usage motivation. Functional design elements:  
1. Intuitive dimension:  
Adopts familiar, intuitive interface design strategies;  
Research shows that using familiar daily objects as interactive input interfaces, coupled with simple intuitive interactive behaviors, effectively reduces the learning thresholds for elderly users;  
This simple, intuitive input interface design not only reduces the learning burden but also enhances usability by aligning with users' habits and needs. Simplicity dimension:  
Considers users' physiological and psychological conditions;  
Designs interaction modes with moderate operational difficulty;  
Research shows that designing universal operation methods that can be performed with any body part effectively enhances elderly users' adaptation to

* Provides personalized design elements to meet different users' needs;
* Research shows that incorporating personalized elements into elderly-centered interactive technology products helps to enhance product preferences and adaptability while maintaining user engagement;
* Examples include providing customized interaction methods for different user groups (such as dementia patients or visually impaired users). This design framework integrates psychological and functional requirements, establishing systematic guidelines for elderly-centered technology product design.
