Embodiment

[0045] Such as figure 1 As shown, a modified real-time emotion recognition method based on eye movement data includes the following steps:

[0046] S1 integrates an eye movement data collection module in a head-mounted VR device. The user wears the VR device to independently explore the content of the 360° panoramic video, collects the user's eye movement data in the process in real time, and obtains the video frame sequence at the same time;

[0047] The eye movement data collection module in this embodiment is specifically an eye movement film, and the eye movement data includes eye patterns, pupil radius, pupil position in the image, upper and lower eyelid distances, fixation points (smooth and non-smooth), etc.

[0048] The beneficial effects of adopting the above solution are: VR immersive experience makes users more immersive, users are less susceptible to interference from the external environment, integrated eye tracking module in the VR headset, the collected data is real-ti...

Abstract

The invention discloses a modified real-time emotion recognition method and system based on eye movement data, and the method comprises the steps: collecting the eye movement data in a VR environmentin real time, and carrying out the prediction of a fixation point through the eye movement data; obtaining a preliminary emotional state through the panorama of the current frame and the predicted fixation point region map of the next frame; and correcting the initial emotional state in combination with historical eye movement data to obtain a final emotional state at the current moment. The system can predict the emotion of the user in real time and improve the experience of the user in the VR environment.

Description

Technical field [0001] The invention relates to the field of emotion recognition, in particular to a modified real-time emotion recognition method and system based on eye movement data. Background technique [0002] With the popularization of virtual reality technology applications, human-computer interaction has received more and more attention. Human-computer interaction in the VR environment, such as eye movement interaction, voice interaction, gesture interaction, and posture interaction, are gradually becoming mature. At present, in terms of emotional interaction, most domestic and foreign researches are based on physiological parameters such as facial expressions, heart rate, EEG, etc. However, the research on emotional interaction based on eye movements in VR is rare, and related research methods also have obvious shortcomings. But in fact, according to psychological research, eyes can best reflect a person's mental state and emotions. [0003] In a virtual reality environ...
