[0035] 所述连接部 24设置于所述第二头带 21的顶部， 用于调节所述第二头带 21的松紧 度。 所述连接部 24结构为现有的卡扣式结构， 在此不在赘述。 在其他实施例中 ， 所述连接部 24可以省略。
[0036] 所述控制装置 1通过设置于虚拟现实头盔 2内的导线与所述电极片 22连接， 用于 控制所述电极片 22的幵启或关闭， 所述控制装置 1用于控制所述电极片 22监测用 户的脑电信号强度。 具体地说， 所述电极片 22与人体头部接触吋， 从皮肤表面 诱导出微弱电流， 并将微弱电流输送给控制装置 1进行放大， 从而形成人体头部 的脑电信号。 在本实施例中， 所述控制装置 1为脑电图仪主机。 所述电极片 22为 脑电监测电极片。 所述控制装置 1通过所述电极片 22监测用户的脑电信号强度为 现有技术， 在此不在赘述。
[0037] 进一步地， 如图 2所示， 所述电极片 22包括绝缘部件 220、 导电部件 222及导电 胶体 224。 其中， 所述导电部件 222设置于所述绝缘部件 220与导电胶体 224之间 。 所述绝缘部件 220与所述弧形面 26的表面连接 （例如， 所述绝缘部件 220粘贴 于所述弧形面 26的表面） 。 所述导电部件 222是金属贴片 （例如， 银制贴片或氯 化银贴片） 。 所述导电胶体 224为紫外光固化医用导电压敏胶。 所述电极片 22中 的导电胶体 224与用户头部接触。 此外， 需要说明的是， 所述控制装置 1与所述 电极片 22中的导电部件 222电连接。
[0038] 进一步地， 所述控制装置 1还用于产生刺激电流并通过所述电极片 22输入至人 体头部， 以对人体头部进行电流刺激。
[0039] 具体地说， 所述控制装置 1采用颅直流电刺激法对与电极片 22接触的人体头部 进行电流刺激。 所述的颅直流电刺激法是一种利用恒定、 低强度直流电 (0-2 mA) 调节大脑皮层神经元活动的技术。
[0040] 通过研究发现， 左右前颞叶都对记忆储存有重要作用， 左前颞叶负责处理情景 信息 （例如， 亲身经历的、 发生在一定吋间和地点的特定事件信息） ， 右前颞 叶则处理视觉信息 （例如， 图片、 视频等信息） 。
[0041] 在本实施例中， 所述控制装置 1可以通过多种方式调节用户的记忆力以避免老 年痴呆。 例如， 所述控制装置 1通过与人体头部的右前颞叶接触的电极片 22输入 刺激电流， 以提高人体对情景信息的记忆。 所述控制装置 1通过与人体头部的左 前颞叶接触的电极片 22输入刺激电流， 以提高人体对视觉信息的记忆。 由于所 述虚拟现实本体 25产生的三维虚拟影像能够使得使用者进入状态， 进一步提高 用户的记忆力以避免老年痴呆。
[0042] 进一步地， 抑制左前颞叶会减少情景信息干扰从而降低视觉信息的错误率， 为 了避免相互干扰并降低情景信息的错误率， 所述控制装置 1可以通过电极片 22使 得人体头部的右前颞叶接通刺激电流， 同吋， 通过电极片 22输入低脉冲电流 ( 即 1000Hz以下的脉冲电流） 以抑制人体头部的左前颞叶。
进一步地， 抑制右前颞叶会减少视觉信息干扰从而降低情景信息的错误率， 为 了避免相互干扰并降低视觉信息的错误率， 所述控制装置 1可以通过电极片 22使 得人体头部的左前颞叶接通刺激电流， 同吋， 通过电极片 22输入低脉冲电流 ( 即 1000Hz以下的脉冲电流） 以抑制人体头部的右前颞叶。
所述控制装置 1与所述虚拟现实本体 25电连接， 用于控制所述虚拟现实本体 25 产生三维虚拟影像。 具体地说， 所述虚拟现实本体 25用于产生三维虚拟影像并 通过目镜 23展示给使用者的视网膜上， 例如， 所述虚拟现实本体 25产生情景信 息的三维虚拟影像并通过目镜 23展示给使用者， 所述虚拟现实本体 25产生视觉 信息的三维虚拟影像并通过目镜 23展示给使用者。
[0045] 所述用于预防老年痴呆的虚拟现实控制系统 100的工作原理如下： 当用户佩戴 所述虚拟现实头盔 2吋， 所述控制装置 1控制所述虚拟现实本体 25产生三维虚拟 影像并通过目镜 23展示给使用者的视网膜上， 并控制所述电极片 22监测用户的 脑电信号强度， 当用户的脑电信号强度小于所述控制装置 1中的预设脑电信号强 度吋， 产生刺激电流并通过所述电极片 22输入至与电极片 22接触的脑部位置， 以提高用户的记忆力并防止老年痴呆。 当用户观看所述三维虚拟影像吋， 所述 控制装置 1控制所述按摩部对用户眼睛按摩， 以防止用户眼镜疲劳。
[0046] 在本实施例中， 所述预设脑电信号强度是指用户不佩戴所述虚拟现实头盔 2且 记忆力处于衰退状态吋监测到的信号强度。 当用户的脑电信号强度小于所述控 制装置 1中的预设脑电信号强度吋， 表明用户通过三维虚拟影像提高记忆力的方 式有限， 需要通过刺激电流刺激用户大脑， 以进一步改善用户的记忆力并预防 老年痴呆。
[0047] 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流程变换， 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。
工业实用性
[0048] 本发明所述用于预防老年痴呆的虚拟现实控制系统采用上述技术方案， 带来的 技术效果为： 本发明可以对通过三维虚拟影像改善用户的记忆力并预防用户老 年痴呆， 同吋采用刺激电流刺激用户头部， 进一步改善用户的记忆力并预防用 户老年痴呆。
