Embodiment

[0039] In this experiment, a visual search experiment was carried out on the 14-step operation of three common tasks in the nuclear power plant boron and water supply system interface. The specific experimental content and process sequence are as follows:

[0040] (1) A single subject enters the laboratory. There are only two subjects in the laboratory, the main tester and the testee, and the environment is kept quiet without other disturbances.

[0041] (2) Let the subjects read the interface introduction of the boron and water supply system and the operation instructions of this experiment for about 5 minutes. At this time, if the subjects have any doubts about the content of the experiment, they can ask the main tester.

[0042] (3) The main tester assists the testee to adjust the viewing distance, screen position and eye tracker parameters in preparation for the experiment.

[0043](4) Carry out experiments. The content of the experiment is as follows: first let the sub...

Abstract

The invention discloses an interactive interface analysis and optimization method related to a visual field position, which can improve the visual search efficiency of an interactive interface and reduce user errors. The visual field position rule, the eye movement index and the interactive interface are combined, a central nest visual area and an auxiliary central visual area are put forward to serve as key areas of a visual search target under task driving, and the visual field position of a target information block corresponding to the task is a key factor of visual search. Therefore, the invention provides an interactive interface analysis and optimization method based on the visual field position. The method includes: Obtaining the size of a display and the sight distance of an operator; Calculating the sizes of the central pit visual area and the auxiliary central pit visual area by using a trigonometric function; Marking a visual area range on the interface; And evaluating the position of the information block based on the visual area range, and performing adjustment. According to the method, the search efficiency can be improved, human errors are reduced, and the security of the interactive interface is improved.

Description

technical field [0001] The invention relates to an analysis and optimization method of an interactive interface based on a visual field position. Background technique [0002] Complex interactive interfaces have a large amount of information, are complex to operate, and control important systems. Mistakes in complex interfaces often have major consequences. However, most of the existing complex interactive interface designs are simple stacking of functional information blocks, which is an empirical design method that does not take into account possible errors that users may cause. [0003] The core of the visual field position theory is that in the three different visual areas of fovea, fovea, and peripheral visual areas, people's visual processing and cognitive abilities are different. As a new theory, the visual position theory has been used in many fields. The existing research on the theory of visual field position has involved many aspects. But when it comes to the ...
