Embodiment Construction

[0050] In order to make the technical problems, technical solutions, and advantages to the present invention, the technical solutions and advantages will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0051]The embodiment of the present invention provides a psychological state data analysis method and a VR system based on image visual cognition, which can be implemented by an electronic device, which may be a terminal or server. Such as figure 1 A psychological status data based on image visual cognition is analyzed by the VR system structure, including:

[0052] Experiment paradigm rendering module, used to view experimental data to the tester.

[0053] In a feasible embodiment, the experimental paradigm consists of a pupil correction section and an image experiment part, a total of 30 sets of tasks, such as figure 2 The experiment flow chart showing a set of tasks. Before the task begins, a white small cross is present in the...

Abstract

The invention provides a psychological state data analysis method based on image visual cognition and a VR system, and relates to the technical field of psychological assessment systems. Comprising the steps that an experiment normal form presentation module presents a test image to a tester; the VR end data acquisition module acquires original eye movement data and pupil data of a testee; the psychological state data analysis module is used for respectively preprocessing and analyzing the original eye movement data and pupil data acquired by the VR end data acquisition module; and the multi-terminal PC management module controls the experiment normal form presentation module, the VR end data acquisition module and the psychological state data analysis module. The invention provides an image free viewing normal form and a task driving normal form based on an attention deviation theory and a pupil reaction theory; an image-based psychological evaluation system with immersion and interactivity is established on lightweight VR equipment, and simultaneous testing of multiple pieces of equipment is realized.

Description

Technical field [0001] The present invention relates to the technical field of psychological assessment systems, in particular to a psychological state data analysis method and a VR system based on image visual cognition. Background technique [0002] In recent years, with the development of polarization theory and the theory of pupil, eye tracking has proven to be an important technical approach to study depression. Note that the bias is pointed out that the depression crowd is more important than that of the normal population for negative stimuli. The pupil reaction theory stated that the depression crowd had a greater pupil expansion and expansion time than normal people under light irritation and emotional stimulus mission. As the inventions of the eye dynamometer, the depression provides a tool, and the eye movement can obtain information such as the gaze direction, watch the trajectory coordinates and pupil diameters when the tester experiment, these physiological informati...
