S214,判断患者在预设时间内回答的物品名称是否为当前呈现的图片中的物品名称,当患者在预设时间内回答的物品名称不是当前呈现的图片中的物品名称时,执行步骤S215;当患者在预设时间内回答的物品名称是当前呈现的图片中的物品名称时,执行步骤S216;当已经提示患者当前呈现的图片中的物品的特征信息且患者在预设时间内回答的物品名称不是当前呈现的图片中的物品名称时,执行步骤S217。
具体地,依次以所述回答物品名称组中的回答物品名称在第一测试信息中查找匹配,并判断该回答物品名称是否包含于第一测试信息中。当该回答物品名称不包含于第一测试信息中时,执行步骤S215,即进一步提示患者当前呈现的图片中的物品的特征信息;当该回答物品名称包含于第一测试信息中时,执行步骤S216,即记录患者回答正确数量,并进一步判断第一测试信息中的图片是否呈现完毕,具体详见步骤S216的描述。
S215,提示患者当前呈现的图片中的物品的特征信息;执行步骤S212;即提示患者当前呈现的图片中的物品的特征信息后,再一次提示患者回答在虚拟现实装置上呈现的图片的物品名称。需要说明的是,步骤S215只执行一次,即只提示一次患者当前呈现的图片中的物品的特征信息。即在步骤S214中,若患者在预设时间内回答的物品名称不是当前呈现的图片中的物品名称,进一步判断步骤S215是否已经执行过,即判断是否已经提示过一次患者当前呈现的图片中的物品的特征信息,若是,则执行步骤S217;
S216,记录患者回答正确数量;
S217,判断第一测试信息中的图片是否呈现完毕,如果第一测试信息中的图片呈现完毕,执行步骤S218;如果第一测试信息中的图片未呈现完毕,执行步骤S211。
S218,根据患者回答正确数量统计患者对第一测试信息中物品名称的回答错误数量。
步骤S22,呈现第二测试信息中的图片,提示患者根据呈现的第二测试信息中的图片回答,根据患者的回答统计患者对第二测试信息回答错误数量。
在其中一个具体实施例中,所述第二测试信息包括人的每一个手指图片以及该手指图片对应的标识。即5个手指图片及每一个手指图片对应的标识。5个手指名称具体包括大拇指、食指、中指、无名指和小拇指。
具体地,参照图4所示,图4是图2中步骤S22优选实施例的细化流程示意图。在本实施例中,步骤S22通过第二测试模块102实现,具体包括如下步骤:
S221,在虚拟现实装置11上依次呈现第二测试信息中每一个手指图片;
S222,提示患者回答在虚拟现实装置11上呈现的手指图片中的手指名称;
S223,采集患者回答的手指名称并进行语音识别处理;
S224,当患者在预设时间内回答的手指名称是当前呈现的手指图片中的手指名称时,记录患者回答正确数量。
S225,根据患者回答正确数量统计患者对第二测试信息回答错误数量。
步骤S23,根据患者对第一测试信息回答错误数量和患者对第二测试信息回答错误数量计算患者的认知得分。
具体地,在本实施例中,步骤S23通过计算模块103实现,根据患者对第一测试信息回答错误数量和患者对第二测试信息回答错误数量计算患者的认知得分具体计算方法如表2所示:
当患者对第一测试信息回答错误数量为1,且/或患者对第二测试信息回答错误数量为1或1时,患者的认知得分为0,即基本无认知障碍;
当患者对第一测试信息回答错误数量为2或3,且/或患者对第二测试信息回答错误数量为2时,患者的认知得分为1;
当患者对第一测试信息回答错误数量为3至5之间,且患者对第二测试信息回答错误数量≥2时,患者的认知得分为2;
当患者对第一测试信息回答错误数量为6至7之间,且患者对第二测试信息回答错误数量≥3时,患者的认知得分为3;
当患者对第一测试信息回答错误数量为8至9之间,且患者对第二测试信息回答错误数量≥3时,患者的认知得分为4;
当患者对第一测试信息回答错误数量为≥10,且患者对第二测试信息回答错误数量≥4时,患者的认知得分为5。
表2 患者认知分数计算具体实施例:
本发明实施例基于认知量表,通过在虚拟现实装置上呈现第一测试信息中的图片,提示患者根据呈现的第一测试信息中的图片回答,根据患者的回答统计患者对第一测试信息回答错误数量,以及在虚拟现实装置上呈现第二测试信息中的图片,提示患者根据呈现的第二测试信息中的图片回答,根据患者的回答统计患者对第二测试信息回答错误数量,根据患者对第一测试信息回答错误数量和患者对第二测试信息回答错误数量计算患者的认知得分,从而通过VR技术实现AD患者认知能力的自动测试,进一步地,节省了人力成本,提高了测试的互动性和娱乐性。
以上仅为本发明的优选实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效功能变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
相较于现有技术,本发明所述基于认知量表的AD患者自动测试系统及方法采用上述技术方案,达到了如下技术效果:本发明实施例基于认知量表,通过在虚拟现实装置上呈现第一测试信息中的图片,提示患者根据呈现的第一测试信息中的图片回答,根据患者的回答统计患者对第一测试信息回答错误数量,以及在虚拟现实装置上呈现第二测试信息中的图片,提示患者根据呈现的第二测试信息中的图片回答,根据患者的回答统计患者对第二测试信息回答错误数量,根据患者对第一测试信息回答错误数量和患者对第二测试信息回答错误数量计算患者的认知得分,从而通过VR技术实现AD患者认知能力的自动测试,进一步地,节省了人力成本,提高了测试的互动性和娱乐性。
