A method and system for evaluating the risk of suicidal ideation of a depressive patient based on a high-altitude virtual scene

By combining VR headsets and physiological monitoring equipment with high-altitude virtual scenes, the physiological and eye movement data of depressed patients are analyzed, which solves the problems of concealment of tendencies and trauma in existing suicidal ideation assessment methods, and achieves accurate and covert assessment of suicidal ideation risk.

AI Technical Summary

Technical Problem

Existing methods for assessing suicidal ideation rely on subjective reports and questionnaires, which have problems such as strong concealment bias, insufficient reliability and validity, and may trigger traumatic experiences in visitors, making it impossible to accurately assess the risk of suicidal ideation in depressed patients.

Method used

By combining VR headsets and physiological monitoring equipment with high-altitude virtual scenarios, and through the analysis of physiological and eye-tracking data, we can assess pain avoidance and acrophobia responses at high altitudes, establish a basis for assessing pain avoidance and acrophobia responses, and objectively assess the suicidal ideation risk of depressed patients.

Benefits of technology

It enables an objective and covert assessment of the risk of suicidal ideation in depressed patients, reduces traumatic triggers, improves the accuracy and covertness of the assessment, and protects the psychological safety of the test subjects.

Abstract

This invention discloses a method and system for assessing the risk of suicidal ideation in depressed patients based on a virtual high-altitude scenario. Subjects wear VR headsets, physiological monitoring devices, and eye-tracking glasses to record resting physiological data (I) and time deviation (I). In a "ground" scenario, a frame-and-bar test is performed, recording the error rate (ER_B). In the virtual high-altitude scenario, a high-altitude pain avoidance test and a time deviation test are performed at a certain height to establish a basis for assessing the subject's pain avoidance. At the maximum tolerable height, subjects perform a body balance test and a time deviation test, recording physiological data (II) and time deviation (III), and then perform the frame-and-bar test and time deviation test again, recording physiological data (III), time deviation (IV), and the error rate (ER_H). A basis for assessing the subject's fear of heights is established, and a risk level assessment of the subject's suicidal ideation risk is made. This invention objectively assesses the risk of suicidal ideation by observing the real performance of depressed patients in predicting effective factors for suicidal ideation.
