Effects of text visual density and interface color hue on digital health education for the elderly
Digital health education has made great contributions to the enhancement of people's health literacy through its rich content and flexible education methods.However,due to the decline of cognitive ability and visual level,the elderly often encounter difficulties in identifying and understanding information during digital education.In this paper,the reading interface of the digital health education platform served as the research object to analyze the impact of interface visual design on the reading effect and cognitive load of the elderly.The independent variables in this study were text visual density(normal density,low density)and interface color hue(cold color and warm color),and the dependent variables were reading performance.The results of the 2×2 two-factor experiment indicated that:① The reading comprehension effect under low text density was better than that under normal density;② The reading comprehension effect with cold color was better than that with warm color;③ There was a significant interaction between text visual density and interface color hue on reading time.Cold color resulted in shorter reading time when paired with normal density,while warm color led to shorter reading time when paired with low density.This study analyzed the interface design from the perspective of health education content communication,enriching the data on digital reading experience for the elderly.It discussed the effect and cross-relationship of text visual density and color hue in the interface,and provided specific design suggestions for enhancing the effectiveness of digital education for the elderly.
