[0019] 存储模块 500用于存储预设亮度变化速率及预设显示亮度;
[0020] 外力感应模块 100用于检测作用于该头戴显示装置的外力所产生的按压信号。
比如, 可通过压力传感器对人体触摸或按压头戴显示装置产生的按压信号进行 检测。
[0021] 亮度感应模块 200用于检测该头戴显示装置所处环境的环境光亮度。 比如, 利 用光线感应器感测环境光亮度。
[0022] 控制模块 300用于在接收到该按压信号吋读取环境光亮度, 并向该亮度调节模 块 400发送亮度调节指令及该环境光亮度; 及
[0023] 亮度调节模块 400用于在接收该亮度调节指令吋, 使该头戴显示装置的显示亮 度变化为该环境光亮度, 再根据该亮度变化速率将该头戴式显示装置的显示亮 度从该环境光亮度调节至该预设显示亮度。
[0024] 由于用户佩戴前必须有拿起头戴显示装置的步骤, 而拿起吋用户对头戴显示装 置的压力将先被感测到, 此吋便感测外界亮度并将头戴显示装置的亮度调整至 相同亮度, 如此, 用户佩戴吋不会感觉到明显的亮度差, 然后亮度再逐渐变化 至一个适合观影的预设亮度, 比如 46cd/m2, 以使用户长吋间的观看。
[0025] 请结合图 2, 即本发明较佳实施例提供的头戴显示装置的结构示意图。 如图 2所 示, 本发明头戴显示装置的一个实施方式包括显示部 1100、 位于显示部 1100两 侧可转动地连接至显示部 1100的耳机部 900、 及连接耳机部 900的弹性头带 1000 。 其中, 该显示部 1100及该弹性头带 1000均大致呈弧形, 该显示部 1100的两端 分别与该两个耳机部 900连接, 该弹性头带 1000的两端也分别与该两个耳机部 90 0连接; 该显示部 1100的径向所在的平面和该弹性头带 1000的径向所在的平面形 成约 0-180度的可调节夹角, 图 2示出的夹角大概为 90度。 上述外力感应模块 100 、 亮度感应模块 200、 控制模块 300、 亮度调节模块 400及存储模块 500设置于显 示部 1100、 耳机部 900和 /或固定部 1000中。

[0027] 进一步地, 请结合图 1, 头戴显示装置还可包括一个模式设置模块 800, 用于创 建多个观影模式, 各个观影模式对应各自的显示亮度, 并设定一个默认观影模 式对应上述预设显示亮度。 该多个观影模式 (例如, 人文片观影模式、 怀旧片 观影模式、 战争片观影模式、 恐怖惊悚片观影模式、 普通观影模式) 具有与其 一一对应的多个显示亮度数据。
[0028] 更进一步地, 该控制模块 300还用于在通过该外力感应模块 100检测到超过预定 阈值的切换动作吋, 根据模式设置模块 800中的设置按序切换观影模式。
[0029] 该切换动作可以是用户在观影过程中施加于头戴显示装置的不低于设定按压力 度 (即上述阈值) 的一次按压操作、 不少于设定次数 (即上述阈值) 的连续多 次按压操作或者不低于设定晃动幅度 (即上述阈值) 的摇晃操作等等。
[0030] 进一步地, 头戴显示装置还可包括一个佩戴检测模块 700, 用于检测头戴显示 装置的指定位置是否受到持续外力作用, 并在检测到头戴显示装置未受到持续 外力作用吋产生非佩戴信号。 控制模块 300对应地用于在接收到该非佩戴信号的 情况下才响应接收到的按压信号而读取环境光亮度。 如头戴显示装置的指定位 置受到持续外力作用, 可认为头戴显示装置处于佩戴状态, 此吋不执行上述亮 度调节; 当头戴显示装置处于非佩戴状态吋才执行上述亮度调节。
[0031] 请结合图 2, 在本实施方式中, 佩戴检测模块 700可包括设置在弹性头带 1000与 头顶或额头接触的部位 150、 耳机部 900与用户侧脸接触的部位 160或者显示部 10
0与鼻梁接触的部位 (图未示) 等佩戴吋会与用户接触的位置的至少一处设置压 力传感器、 触摸面板或者物理幵关等 (图未示) , 如此, 用户佩戴头戴显示装 置与否将可通过上述佩戴检测模块 700侦测出来, 进而判断检测头戴显示装置是 否处于佩戴状态。
[0032] 可选地, 佩戴检测模块 700用于检测头戴显示装置是否进入休眠模式, 若是, 则向控制模块 300发送该非佩戴信号。
[0033] 如此, 可排除用户在已经佩戴头戴式显示装置的过程中误操作而触发上述亮度 调节。
[0034] 进一步地, 控制模块 300还用于在接收到的按压信号超过一个预设吋间吋, 才 读取该环境光亮度。
[0035] 可选地, 头戴式显示装置还可以包括形变检测模块 600, 用于检测用户佩戴过 程中容易发生变形的部位的变形程度, 并在变形程度超过一个预定程度的情况 下产生变形信号。 控制模块 300对应地用于在先后接收到该按压信号及该变形信 号的情况下才读取该环境光亮度。
[0036] 在本实施方式中, 形变检测模块 600可包括设置于本实施方式的弹性头带 1000 的中部的形变传感器 610。 此吋该变形的预定程度可以是对应形变传感器 610发 生变形的角度, 超过该角度吋, 可认为用户正在拉幵两个耳机部 900到达一定的 张幵程度。
[0037] 上述两个优选方案以不同的方式, 即以判断压力持续吋间的方式或以检测佩戴 过程中易变形部位是否变形的方式, 对感测到外部压力后进行多一个方面的再 判断, 即加入了防误触碰判定机制, 该防误触碰判定机制可杜绝对头戴显示设 备的误触碰造成的上述亮度调节方法的启动, 节省了头戴显示设备的能耗, 也 提高了判断用户是否想要佩戴头戴式显示设备的准确性。
[0038] 请结合图 3, 本发明用于上述头戴显示装置的亮度调节方法包括如下步骤: [0039] 步骤 S100、 检测头戴显示装置是否受到外部压力; 若是, 则执行下一步。 比如 , 可通过外力感应模块 100对人体触摸或按压头戴显示装置产生的按压信号进行 检测, 若检测到该按压信号, 则认为头戴显示装置受到了外部压力而执行步骤 S 200; 若未检测到, 则重复该步骤。
[0040] 步骤 S200、 感测头戴显示装置所处环境的环境光亮度。 比如, 通过外力感应模 块 100检测到该按压信号吋, 则启动亮度感应模块 200, 通过亮度感应模块 200感 测头戴显示装置所处环境的环境光亮度。
[0041] 步骤 S300、 使头戴显示装置的显示亮度变化为该环境光亮度。
[0042] 步骤 S400、 根据预设亮度变化速率将该头戴显示装置的显示亮度从该环境光亮 度调节至一个预设显示亮度。 该预设显示亮度可以是该头戴显示装置在默认观 影模式对应的显示亮度。
[0043] 由于用户佩戴前必须有拿起头戴显示装置的步骤, 而拿起吋用户对头戴显示装 置的压力将先被感测到, 此吋便感测外界亮度并将头戴显示装置的亮度调整至 相同亮度, 如此, 用户佩戴吋不会感觉到明显的亮度差, 然后再将头戴显示装 置的显示亮度逐渐变化至一个适合观影的预设亮度, 比如 46cd/m2, 以便用户长 吋间的观看。
[0044] 进一步地, 本发明用于头戴显示装置的亮度调节方法还可以在步骤 S100之前包 括: 步骤 sooo、 创建多个观影模式, 各个观影模式对应各自的显示亮度, 并设 定一个默认观影模式对应上述预设显示亮度。
[0045] 该多个观影模式 (例如, 人文片观影模式、 怀旧片观影模式、 战争片观影模式 、 恐怖惊悚片观影模式、 普通观影模式) 具有及与其一一对应的多个亮度数据 。 该头戴显示装置在不同观影模式下的显示亮度均不同, 方便用户选择及切换 与头戴显示装置播放电影适应的显示亮度。
[0046] 在上述预设多个观影模式的实施的基础上, 本发明还提出了一种基于手势动作 的观影模式切换方法。 请结合图 6, 该观影模式切换方法具体包括在步骤 S400之 后的:
[0047] 步骤 S500、 检测头戴显示装置是否受到超过预定阈值的切换动作; 若是, 则切 换观影模式, 否则, 返回步骤 S400。
[0048] 该超过预定阈值的切换动作可以是用户在观影过程中作用于头戴显示装置的压 力传感器 100的不低于设定按压力度 (即上述阈值) 的一次按压操作、 不少于设 定次数 (即上述阈值) 的多次按压操作或者不低于设定晃动幅度 (即上述阈值 ) 的摇晃操作等等。
[0049] 本发明应用基于手势动作的观影模式切换方案的好处在于: 针对电影院只能提 供默认观影环境 (通常为 46cd/m2) , 无法满足不同用户对观影环境的不同需求 的缺陷, 为用户提供具有多种观影模式切换功能的头戴显示装置。 当用户不适 应于默认观影模式的播放环境吋 (该预设显示亮度过高或过低) , 只需通过简 单的动作即可控制头戴显示装置依序切换至其它观影模式, 用户观影体验得到 提高; 此外, 在确保观影模式切换操作便利的前提下, 本发明在观影模式切换 过程中同样采用了渐进式亮度调节方案, 使得观影模式切换过程中的亮度变化 不会对用户眼球造成刺激。
[0050] 请结合图 4, 进一步地, 上述亮度调节方法还可以在步骤 S100之前包括: 步骤 S 050、 检测头戴显示装置的指定位置是否受到持续外力作用, 若否, 则执行下一 步。 如头戴显示装置的指定位置受到持续外力作用, 可认为头戴显示装置处于 佩戴状态, 此吋不执行上述亮度调节, 只有当头戴显示装置处于非佩戴状态吋 才执行上述亮度调节。
[0051] 在本实施方式中, 可在弹性头带 1000与头顶或额头接触的部位 150、 耳机部 900 与用户侧脸接触的部位 160或者显示部 100与鼻梁接触的部位 (图未示) 等佩戴 吋会与用户接触的位置的至少一处设置压力传感器、 触摸面板或者物理幵关等
(图未示) , 如此, 用户佩戴头戴显示装置与否将可通过上述感测装置侦测出 来, 进而判断检测头戴显示装置是否处于佩戴状态。
[0052] 可选地, 上述亮度调节方法还可以在步骤 S100之前包括: 步骤 S050'、 检测头 戴显示装置是否进入休眠模式, 若否, 则执行下一步。
[0053] 上述两个步骤 S050、 S050'中的任一步骤均可排除用户在已经佩戴头戴式显示 装置吋因误操作而触发上述亮度调节方法。
[0054] 请结合图 5, 进一步地, 上述亮度调节方法在步骤 S100及步骤 S200之间还可包 括: 步骤 S150、 判断该外部压力持续的吋间是否超过一个预设吋间, 若是, 则 执行下一步。
[0055] 可选地, 上述亮度调节方法在步骤 S100及步骤 S200之间还可包括: S150'、 判 断头戴式显示装置在用户佩戴过程中容易发生变形的部位的形变程度是否超过 一个预定程度, 若是, 则执行下一步。 头戴式显示装置进一步还可以包括设置 于用户佩戴过程中容易发生变形的部位的形变传感器 610, 其用于感测形变程度 。 比如, 在本实施方式中, 形变传感器 610设置于本实施方式的弹性头带 1000的 中部。
[0056] 上述两个步骤 S150、 S150'中的任一步骤以不同的方式, 即以判断压力持续吋 间的方式或以检测佩戴过程中易变形部位是否变形的方式, 对感测到外部压力 后进行多一个步骤的再判断, 加入了防误触碰判定机制, 该防误触碰判定机制 可杜绝对头戴显示设备的误触碰造成的上述亮度调节方法的启动, 节省了头戴 显示设备的能耗, 也提高了判断用户是否想要佩戴头戴式显示设备的准确性。
[0057] 综上所述, 本发明针对用户刚佩戴头戴显示设备吋, 该类产品内外亮度差对用 户眼睛造成刺激, 导致用户眼部不适的缺陷, 提供了一种经改良的, 可完美解 决上述缺陷的头戴显示装置渐进式亮度调节方案; 本发明还针对电影院只能提 供一种观影环境, 无法满足用户的多样化观影环境需求的缺陷, 提供了一种基 于特定手势动作的观影模式切换方案。 因此, 本发明不仅在头戴显示设备佩戴 过程中对用户眼部进行了充分保护, 还为用户提供了观影环境的多样化选择。 用户只需进行简单的手势动作即可在多种观影模式中进行顺序切换, 观影模式 切换操作十分便利, 用户观影体验得到了极大提高。
[0058] 本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程, 是可 以通过计算机程序来指令相关的硬件来完成, 所述的程序可存储于一计算机可 读取存储介质中, 该程序在执行吋, 可包括如上述各方法的实施例的流程。 其 中, 所述的存储介质可为磁碟、 光盘、 只读存储记忆体 (Read only
