Eye movement technology-based emotion measurement system and method

Abstract

The invention discloses an eye movement technology-based emotion measurement system. The system comprises a data acquisition module, an A / D converter, an FPGA controller, a DSP controller, a data preprocessing module, a data analysis module and an emotion state confirmation module. The invention further provides an eye movement technology-based emotion measurement method. According to the system of the invention, the data acquisition module is used for acquiring the eye movement information and facial image of a testee; the data preprocessing module is used for preprocessing the eye movement information and the facial image; the data analysis module analyzes and processes the preprocessed eye movement information and facial image through a clustering-based SVM multi-classification method;and the emotion state confirmation module is used for fusing the analyzed and processed eye movement information and facial image and then performing comparison so as to obtain the final emotion stateof the testee. With the system adopted, the emotion state of the testee can be comprehensively, systematically and quantitatively recognized, so that the emotion state can be accurately and efficiently recognized, and therefore, the thinking state of the testee can be interpreted. The method has a bright application prospect.

Description

technical field [0001] The invention belongs to the technical field of emotion cognition, and more specifically, relates to an emotion measurement system based on eye movement technology, and also relates to an emotion measurement method based on eye movement technology. Background technique [0002] Eye movement trajectory is the sequence of fixation points changing with time in the process of gazing at things. It dynamically reflects the eye activity of people in the process of reading, driving, sports, etc. Eye movement trajectory contains very rich information. [0003] At present, interpreting people's thinking state from people's eye movement trajectories has become a research hotspot in applied psychology. However, in many fields of eye movement research, such as: eye movement research of reading; eye movement research of picture viewing, visual search and pattern recognition; eye movement research of traffic psychology; application of eye movement in aviation psychol...

AI Technical Summary

Problems solved by technology

[0004] Such methods are all about the analysis of the static indicators of the eye movement trajectory, and lack the analysis of the entire dynamic indicators of the eye movement trajectory.
