Acrophobia evaluation system based on virtual reality and eye movement brain wave detection

Abstract

The invention discloses an acrophobia evaluation system based on virtual reality and eye movement brain wave detection. The system comprises a test scene design module, a test scene selection module,a data collecting and processing module and an acrophobia judgment module; the data collecting and processing module collects the real-time eye movement gaze point trajectory of a testee entering different test scenes through an eye movement detector, collects the real-time brain wave signal of the testee entering different test scenes through a brain wave detector, processes the brain wave signal, and performs emotion judgment according to the processing result; the acrophobia judgment module judges that the testee has acrophobia and outputs the judgment result if the time duration of an eyemovement gaze point in a set height range is smaller than a set time threshold or the motion judgment indicates that the testee is scared, otherwise, the acrophobia judgment module judges that the testee has no acrophobia, the test scene selection module runs again to select a next test scene until all test scenes are selected, and the judgment result is output.

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 ...
