基于自适应的弱视儿童训练系统的设计与实现

Design and Implementation of a Children Amblyopia Treatment System Based on Adaptive Procedures

目前已有儿童弱视训练系统都存在训练级别固定、不能实时调整等问题,且未在适宜的视觉刺激参数设置下进行训练,极大影响了患者认知能力发展、训练积极性和疗效。为此,本研究引入心理物理学方法中的自适应法,设计并实现了一种新的弱视儿童训练系统,该系统能根据患者的训练情况实时调整训练难度,并通过比较训练结果自动调整视刺激模块的相关参数,使患者在适宜的视觉刺激下进行训练。实际使用表明,系统运行稳定,并能取得较好的使用效果。

All ot the existing amblyopic children training systems have problems,like a fixed level of training and cannot be adjusted in real time;and these systems do not training under the appropriate visual stimulation parameter settings,which greatly affect the development of the patients' cognitive ability,training activity and treatment effect.For this reason,the study designed and implemented a new amblyopic children training system with adaptive procedures of psychophysics.This system can be adjusted to the difficulty of training in real time according to the patients and altered the relevant parameters of visual stimulation module by comparing training results,which makes the patients can train in an appropriate visual stimulation.By practically using,this system runs stable and brings better effects.
