Evaluation system for fear of heights based on virtual reality and eye movement brainwave detection

Abstract

The invention discloses a fear of heights evaluation system based on virtual reality and eye movement brain wave detection, comprising: a test scene design module; a test scene selection module; Real-time eye movement gaze point trajectory; real-time brain wave signals of the test subject entering different test scenarios are collected by the brain wave detector, the brain wave signals are processed, and emotion judgment is made according to the processing results; fear of heights judgment module: if eye movement is fixed If the time length below the set height range is less than the set time threshold, or the emotion is judged to be panic, it is judged that the test subject is afraid of heights, and the judgment result is output; otherwise, it is judged that the test subject is not afraid of heights, and returns to the test scene selection module Select the next test scene until all test scenes are selected, and output the judgment result.

Description

technical field [0001] The invention relates to the field of medical and health technologies, in particular to a fear of heights assessment system based on virtual reality and eye movement brainwave detection. Background technique [0002] Acrophobia, also known as fear of heights. Fear of heights exists in everyone to varying degrees. Severe cases have extremely unreasonable fear and worry about high places, which is usually diagnosed clinically as fear of heights. The specific manifestations of acrophobia are: when the patient is in a high-altitude environment, the visual information is greatly reduced, coupled with psychological factors, leading to the collapse of the human body balance system, resulting in a sense of oppression about to fall and extreme panic, nervousness, fear, dizziness, palpitation, breathing, etc. Symptoms such as shortness of breath. Patients with acrophobia cannot face high places, even cannot fly or climb mountains. Acrophobia has brought a lot ...

Problems solved by technology

[0004] Foreign countries also use virtual reality technology to assess acrophobia. The Physiological acrophobia evaluation through invivoexposure in a VR CAVE published by P. Costa, James Robb, Lennart E. Nacke uses virtual reality technology and brain wave detection, but it cannot accurately combine the patient's visual field changes with brain wave changes
