The Information-Seeking Behavior of Visually Impaired People in the Context of Public Health Emergencies——A Method of Contextual Task-Based Experimentation
[Purpose/significance]The information-seeking behavior of visually impaired people in public health emergencies is unique compared with that of normal people.Therefore,effective evaluation and improvement of the information ability of visually im-paired people in public health emergencies is conducive to achieving information fairness.[Method/process]This study set up three specific situations,namely epidemic awareness,travel and basic daily life,and constructed four kinds of situational tasks with different complexity and urgency.Finally,35 samples were collected,and tested using the normality test of SPSS22.0 and the Mann-Whitney U nonparametric test module.[Result/conclusion]In the context of public health emergencies,the tools,steps and search results in the epidemic situation are better than other specific situations;Visually impaired people have certain perception of the complexity and ur-gency of tasks in different situations;The information-seeking behavior of visually impaired people shows the characteristics of path dependence,alternative searching and recognition difficulty.[Innovation/limitation]This study integrates the interview conclusion into the experimental design,enriches the situational task experiment practice,and proposes strategies such as barrier-free optimiza-tion and situational assistance to improve the information ability of the visually impaired;The size of the samples in this study can be enlarged,and future research can be improved by setting up more crucial contexts.
