### Factors Affecting the Usability of Interface Design
#### 3.2.4 User Experience
Clear explanations, tutorials, or contact information should be provided for errors [13], along with enhanced accessibility features such as text-to-speech, a high contrast mode, and a simplified interface for users with varying abilities [69]. _(6) User-centered._ Telemedicine interfaces for the elderly should prioritize a user-centered design by involving older consumers in the development process to meet their specific needs and preferences [69]. Applications must be accessible, easy to use, and efficient [66], promoting the acceptance of telemedicine and enhancing independent living. Tailoring the design to the unique characteristics and habits of older adults is crucial to ensure rapid response times and minimal loading delays for an optimal user experience [61; 69; 74]. The application should function as intended to prevent negative emotions or self-blame [68]. Based on the above analysis, the interface design guidelines for the elderly have been organized based on functional design, interaction logic, visual design, and user experience, as shown in Table 2. \begin{table}
