Effects of Visual Location of Information on The Performance of Monitoring Task Searhing in Digital Interactive Interface

The visual location of the information influences the searching efficiency of the monitoring task. In this paper, from the division of human eye’s visual regions, the task searching experiments of visual location in digital interactive interface are conducted. The experimental results show that, for target information blocks in the foveal and the parafoveal regions, the operators can finish the task searching efficiently and rapidly. However, when the target task is away from present fixation range’s parafoveal region, it will easily lead to sequence searching that will cost extra unnecessary task searching time, or even lead to failure of task searching. Therefore, the information layout design of digital interactive interface should be set successively in effective visual locations, i.e., the foveal and the parafoveal regions according to task order. This will satisfy the visual location rule and will efficiently improve the performance of task searching.
