Abstract

The present invention discloses a real-time evaluation method and evaluation system of VR immersion effect, collects EEG signals while playing VR video, and calculates the degree of emotional arousal and cognitive focus in real time based on the α, β, and θ frequency band energy obtained after wavelet transformation degree, and finally obtain the dynamic monitoring immersion effect index, which is used for objective evaluation of immersion effect. The present invention realizes real-time measurement and analysis, and can dynamically monitor the immersion effect of VR video procedurally. The index adopts a multi-dimensional comprehensive calculation strategy and takes into account individual differences, effectively solving the post-event reporting and social expectations of questionnaire measurement and other means. Deviation, strong subjectivity and other problems, has a wide range of market application prospects.

Description

technical field [0001] The invention belongs to the intersection field of information science and cognitive neuroscience, and specifically relates to a real-time evaluation method and evaluation system of VR immersion effect. Background technique [0002] Immersion refers to making individuals focus on the current target situation, participate in and substitute into the cognitive and emotional state related to the target situation, and forget the real external environment. The evaluation of immersion effect mainly includes two aspects: the degree of cognitive focus and the degree of emotional arousal. [0003] Virtual Reality (VR) technology is developed by integrating computer graphics, stereoscopic display, simulation, multimedia, sensing, network, human-computer interaction and other multi-field and multidisciplinary technologies. It is currently used in military, medical, psychological, It has a wide range of applications in education and business. The core goal of VR ...
