Eye movement data-based user help information automatic triggering apparatus and method

Abstract

The invention relates to the technical field of human factors engineering, in particular to an eye movement data-based user help information automatic triggering apparatus. The apparatus comprises an eye movement tracking apparatus, an automatic triggering module arranged in an operation system and connected with the eye movement tracking apparatus, and a display terminal connected with the automatic triggering module. Meanwhile, the invention furthermore provides an eye movement data-based user help information automatic triggering method. The method comprises the steps that the eye movement tracking apparatus acquires an eye movement track of a user and generates an eye movement data sequence; the automatic triggering module calculates a real-time movement distance of the eyes of the user according to the eye movement data sequence and a preset threshold distance; and when the real-time movement distance of the eyes of the user is smaller than or equal to the preset threshold distance for multiple continuous times, the display terminal presents user help information. According to the apparatus and the method, the cognition of the user is assessed by counting a value relationship between the real-time movement distance of human eyes and the threshold distance for multiple times, so that the adaptability of man-machine interaction is remarkably improved and the efficiency and effect of user help information display are improved.

Description

technical field [0001] The present invention relates to the technical field of human factors engineering, in particular to a device and method for automatically triggering user help information based on eye movement data. Background technique [0002] At present, the driving of system information display in the process of human-computer interaction mainly includes two modes: task-driven mode and user-driven mode. In the task-driven mode, the task process expected to be completed by the user drives the information display sequence and duration of each link. For example, in the personal email system, when the user executes the subtask of a specific operation link during the process of sending E-mail After completion, the system will display the interactive interface and information corresponding to the next subtask driven by the task; in the process of active driving by the user, the user will pass a specific operation based on the comprehensive perception and judgment of the ...

AI Technical Summary

Problems solved by technology

[0003] The above two main information display driving modes have the following problems for information display: (1) User help information, in the process of information system design and development, is difficult to be automatically integrated into the specific task execution process, so , the task is difficult to drive the trigger display of the user's help information; (2) In the user active driving mode, when the user performs a complex human-computer interaction task and the user's mental load and cognitive load are high, the user actively drives the help information The efficiency of the display is not high, and it will interfere with the main task, thereby affecting the user's operating experience
