Design Of User Data Visualization System Based On Task Model

In the era of mobile internet,industrial interfaces urgently need the support of data visualization tools for the rapid growth of massive user data in order to effectively analyze user data,understand user experience and needs better,and guide product design and innovation.User data analysis by user experience professionals is a highly complex task.Designing and developing a data visualization system for such a task is difficult in how to perform task analysis and modeling of user data analysis and identify user's requirements,to guide the interactive design,development and evaluation of the system.The author of this article attempts to use task analysis to perform task analysis and modeling on user data analysis practices for user experience design,and analyze user requirements,system interaction design,implementation,and usability evaluation with the support of task models.This article is divided into three parts:User data analysis task modeling:Iterative thinking is used to understand the entire data analysis process of User Experience(UX)researchers,and the HTA task model is used for hierarchical task analysis,and the data analysis tasks are decomposed and modeled.Then extract UX researcher's requirements based on the task model.The interface design of the visualization system:the WISDOM task model is used to further decompose user tasks in the form of an optimal tree,and the resulting representation model represents the mapping of user requirements obtained by the HTA model to the interface of the visualization system.Then interactive design,and the interactive process design reflects the interaction of the interface process,and the design optimization isperformed through multiple rounds of iterations.Evaluation and testing of the visualization system:UX researchers use the data visualization system to analyze user data based on actual user experience research projects,verify the effectiveness and value of the system through indicators such as operating steps and efficiency,and use software testing methods Perform functional tests on the system.The research results show that,Using user data visualization system for data analysis can reduce the 30%steps of data analysis and improve the 51%efficiency of data analysis by UX researchers;Compared with the use of other data analysis tools,it can help UX researchers intuitively view and discover the correlation between data;It can help UX researchers analyze user behavior patterns and discover user experience problems.It also shows that the task model can effectively help to obtain user needs and guide the interface design,thereby providing new ideas for user needs analysis and user interface design of data visualization.
