Virtual reality (VR) is one of the hot spots in the computer network world in recent years, which has attracted more and more people's attention. This study mainly explores the effect of mitigating the psychological trauma of adult burn patients based on the VR technology of smart medical treatment. First, the EEG data are sent to the data processing module through a wireless protocol; then, the data processing module denoises the EEG data and performs feature extraction and feedback parameter calculation; after that, these parameters will be sent to the VR interaction engine; based on this, these parameters change the VR scene to capture and reflect the physiological activities of the patient's brain in real time; finally, the patient uses the VR scene content presented by the real-time feedback of the captured EEG signal as a guide to making self-adjustment in time, and the electrical signal of captured brain at this time is again transmitted to the next work cycle and continues to feed back and present new VR interactive scenes to guide and intervene in the patient's self-regulation behavior. The VR feedback training module is responsible for receiving the characteristic data calculated from the EEG acquisition and processing module and converts it into parameter variables that control the VR intervention system. The system user adjusts the state according to the feedback information displayed in the VR scene and generates new EEG signals to promote the realization of self-adjustment. The biofeedback training based on EEG feeds back the intuitive EEG state to the patient, prompting them to learn how to realize self-regulation and achieve the purpose of adjusting the level of mental health. The degree of itching and pain in the VR treatment group was alleviated, and compared with the normal training treatment results, it was statistically significant ( > 0.05). This study has a positive effect on the psychological intervention of patients with facial injuries.
虚拟现实(VR)是近年来计算机网络世界的热点之一,引起了越来越多人的关注。本研究主要探索基于智能医疗 VR 技术减轻成人烧伤患者心理创伤的效果。首先,通过无线协议将 EEG 数据发送到数据处理模块;然后,数据处理模块对 EEG 数据进行去噪,并进行特征提取和反馈参数计算;此后,这些参数将被发送到 VR 交互引擎;基于此,这些参数改变 VR 场景,实时捕捉和反映患者大脑的生理活动;最后,患者使用实时反馈捕捉 EEG 信号的 VR 场景内容作为及时自我调整的指导,此时捕捉到的大脑电信号再次被传输到下一个工作循环,并继续反馈和呈现新的 VR 交互场景,以指导和干预患者的自我调节行为。VR 反馈训练模块负责接收从 EEG 采集和处理模块计算出的特征数据,并将其转换为控制 VR 干预系统的参数变量。系统用户根据 VR 场景中显示的反馈信息进行调整,并生成新的 EEG 信号,以促进自我调节的实现。基于 EEG 的生物反馈训练将直观的 EEG 状态反馈给患者,提示他们学习如何实现自我调节,从而达到调整心理健康水平的目的。VR 治疗组的瘙痒和疼痛程度得到缓解,与正常训练治疗结果相比,差异具有统计学意义(>0.05)。本研究对面部损伤患者的心理干预具有积极作用。
