Research On Visual Search Behavior Characteristics Of Different Types Of Visual Complexity Under News Client And Its Relationship With User Satisfaction

In the era of mobile Internet,people's access to information from the past paper media,the Internet era of personal computers to the current mobile devices,the search for information on small screen mobile devices undoubtedly presented more challenges to the public.How to design visual complexity on the mobile side to facilitate the user's visual search task,this paper will study from both visual search behavior and visual search satisfaction.Based on the previous research results,this paper classifies the visual complexity in the mobile news client,and studies the impact of complexity change on visual search behavior and visual search satisfaction.The content is as follows:(1)Mobile news client prototyping:The client page complexity type is divided into three types,namely quantity complexity,graphic complexity and layout complexity,and product prototype design through ink knife software.(2)Visual search experiment:Visual search experiments were performed on each type of complexity,and the eye movement data of the subjects were recorded,subjective questionnaires were filled out to obtain the cognitive load and subjective satisfaction of the subjects.(3)Data processing and analysis:The collected data are statistically analyzed,and the experimental results under different complexity types are analyzed by repeated measures of variance according to the complexity level,and then the change law is understood through paired analysis.(4)The establishment of eye movement index and satisfaction relationship model:the eye movement index with significant performance under each complexity type in data analysis is used as a model for the relationship between self-variable and satisfaction.The main conclusions obtained are as follows:(1)Under different types of complexity,the changes in eye movement behavior caused by the increase in complexity in visual search tasks are different.(2)Under different types of complexity,the cognitive load and satisfaction changes of the subjects were different,and the two showed strong negative correlation.(3)Under different complexity types,the visual search behavior of the subjects was different from the satisfaction degree.
