具体地, 本优选实施例中的用于演示投影的手机可以包括蓝牙耳机和投 影手机两个部分。 其中, 蓝牙耳机包括: 无线通讯模块, 设置为负责蓝牙耳 机与手机的配对和无线通讯,是耳机侧与手机侧进行语音和数据传输的通道; 语音模块, 包括蓝牙耳机的麦克风和扬声器,设置为负责声音的釆集和播放; 按键输入模块, 设置为接听 /挂断通话以及控制耳机音量大小。 在具体实施过 程中, 蓝牙耳机还可以包括其它更多按键输入, 例如, 静音等功能操作也属 于该模块范围。 除以上蓝牙耳机的功能模块之外, 本发明优选实施例在投影手机部分增 加了如下功能: 在投影手机基带芯片上启动投影演示功能, 并响应蓝牙耳机 控制器的驱动模块(基带软件模块),接受控制命令并对当前投影演示文档产 生与手机键盘功能键操作相同的动作; 投影手机所运行的文档演示软件识别 该操作, 并完成对投影数据的显示切换。 可见,蓝牙耳机作为手机最为常用的配件,具备与手机无线通讯的功能, 本优选实施例通过对投影手机进行功能改进, 使之既能使用蓝牙耳机作为普 通无线耳机进行通话, 也能够作为控制投影手机的无线控制器使用。 优选实施例二 本优选实施例提供了一种用于演示投影手机的无线控制方法, 实现控制 投影演示内容的功能包括以下步骤: 步骤 1 , 耳机侧无线模块与手机侧无线模块的正常连接, 建立数据传导 通路。 步骤 2, 当手机处于正常待机模式时, 手机基带软件模块将蓝牙耳机的 按键输入识别为正常功能输入, 可以控制来电的接听 /挂断, 以及通话音量的 大小调整。 步骤 3 , 当投影手机开启演示功能时, 基带软件模块切换至投影演示模 式, 将蓝牙耳机产生的按键输入识别为用户输入的控制命令, 用于控制投影 内容的切换操作(例如, 全屏切换、 上翻页、 下翻页动作)。 如果此时手机有 来电, 基带软件模块切换回通话模式, 响应蓝牙耳机的接听 /挂断及音量调整 操作。
步骤 4, 当投影手机开启演示功能并且当前处于全屏显示模式时, 如果 手机有来电, 在当前投影内容上添加显示来电指示, 通知用户接听电话。 但 此时基带软件模块仍将蓝牙耳机的按键输入识别为控制命令, 保持当前投影 演示及控制功能, 以便用户忽略来电, 继续演示。 步骤 5 , 对于步骤 4的情况, 如果用户需要接听电话, 可以点击全屏显 示切换按键, 退出全展模式, 此时基带软件模块切换回无线语音通话模式, 将蓝牙耳机的按键输入识别为接听 /挂断功能, 再次点击接听按键, 可以接听 来电。 接听完毕, 基带软件模块重新切回投影演示模式。 步骤 6, 手机演示投影功能使用结束后, 基带软件模块恢复正常无线通 话功能, 运行步 4聚 2。 本优选实施例通过对现有无线耳机功能的改进, 以及对投影手机增加相 应软件驱动模块, 使其具备了使用蓝牙耳机遥控投影手机投影显示内容的功 能, 实现了一种具备无线通话和投影控制双功能的蓝牙耳机。 并且, 可以使 用户在讲演过程中脱离手机操作限制, 在室内范围自由移动并能够控制切换 投影显示。 优选实施例三 图 5是才艮据本发明优选实施例三的用于演示投影手机的控制方法的蓝牙 耳机示意图, 如图 5所示, 分别用 1-5分解标示了该蓝牙耳机的主要组成结 构: 用 1指示了蓝牙耳机的接听 /挂断按键; 用 2指示了蓝牙耳机的音量调节 按键; 用 3和 4指示了蓝牙耳机的话筒和听筒; 用 5指示了蓝牙耳机的机身。 此外, 该蓝牙耳机还可以包括内部电路和无线收发模块。 图 6是根据本发明优选实施例三的使用蓝牙耳机控制器控制投影演示的 使用示意图, 如图 6所示, 以蓝牙作为无线通讯模块的蓝牙耳机为例, 提供 一种可行的实施方式: 正常工作情况下, 当手机有来电时, 可以选择通过按键 1接听电话, 接 听结束后使用按键 1挂断电话, 听筒 4的音量可以通过音量调节按键 2来调 整; 当手机启用投影功能时, 基带芯片的蓝牙软件模块切换至无线控制工作 模式, 用户可以使用该蓝牙耳机作为投影手机的控制器使用。 例如, 在无线 控制工作模式下,蓝牙耳机的接听 /挂机按键 1和音量调节键 2的功能分别被 投影手机的软件模块映射为控制演示文档的全屏切换键和上下翻页键。
本发明实施例以手机最为常用的配件蓝牙耳机为改进平台, 不需要对手 机和蓝牙耳机的硬件故任何改动,而只需要对现有投影软件驱动功能的集成, 克服了原有投影手机在演示过程中所存在的弊端, 也不需要为手机增添新的 无线控制配件, 具有简单、 可靠、 成本低廉的优点, 能够提高用户对投影手 机的用户体 -险。 需要说明的是, 在本实施例中提供的可以控制投影手机演示内容的耳机 是基于现有 3功能键 (即, 1个接听键和 2个音量调节键) 的无线耳机改进 开发的。 如果无线耳机自身包括更多功能键, 通过添加状态切换开关后, 可 以映射出更多的投影演示控制按键, 或者使用控制按键的组合键派生更多控 制命令, 也都属于本专利的保护范围。 本说明书的内容和举例只是对一种用 于演示投影手机的无线耳机的原理和方法的阐述, 而不应理解为对本发明的 限制。 优选实施例四 图 7是根据本发明优选实施例四的使用蓝牙耳机作为投影手机的演示控 制器的正常工作流程图, 如图 7所示, 该流程可以包括以下步 4聚: 步骤 S702, 耳机中的蓝牙模块完成与投影手机的蓝牙配对, 建立数据传 导通路。 步骤 S704, 投影手机开启投影演示功能, 基带软件模块识别到手机当前 工作状态, 转入投影演示的无线控制模式; 当用户在蓝牙耳机上有按键 1和 2的输入操作时, 产生的数据通过蓝牙协议发送至手机基带芯片的软件控制 模块, 软件模块识别按键输入类型, 并将其映射为所对应的投影控制命令。 步骤 S706, 根据蓝牙耳机所产生的控制命令, 向上层投影演示软件上报 控制事件, 进而产生相应的全屏切换和翻页操作的动作。 步骤 S708, 投影演示功能关闭时, 基带软件模块退出无线控制模式, 返 回蓝牙语音模式, 等待手机来电及蓝牙耳机的来电控制命令。 优选实施例五 图 8是根据本发明优选实施例五的使用蓝牙耳机作为投影手机的演示控 制器在出现来电时的工作流程图, 如图 8所示, 当投影手机在投影演示过程
中遇到手机来电时, 需要根据当前是否全屏演示来决定基带软件模块对蓝牙 按键输入的识别, 具体步骤可以为: 步骤 S 802 , 当投影手机使用投影演示功能时, 基带软件模块切换至无线 控制工作模式。 步 4聚 804, 手机来电时, 如果当前投影手机处于全展演示状态时, 基带 软件模块的工作模式不切换, 仍然将蓝牙耳机的控制命令数据识别为投影控 制命令; 上层显示软件模块在当前投影内容上叠加显示手机来电指示图标, 告知用户有新电话打入。 步骤 S806, 当用户需要接听时, 点击蓝牙耳机(控制器) 的全屏切换按 键, 使投影手机推出全屏演示状态, 此时基带软件模块切换回蓝牙语音通话 模式, 等待用户通过按键开启和结束语音通话。 步骤 S808, 当通话结束后, 如果手机投影功能尚未关闭, 基带软件再切 换至无线控制模式; 如果手机投影功能已关闭, 则保持蓝牙语音通话模式。 需要说明的是, 以上实施方式以蓝牙通讯协议的蓝牙耳机为例, 提供了 一种使用无线耳机无线控制投影手机进行投影演示的方法。 对于其它无线耳 机, 例如, 基于射频的无线耳机、 基于 WLAN的无线耳机、 基于 ZigBee的 无线耳机等能够实现无线通讯的耳机, 釆用本发明实施例中提供的改进和功 能拓展方案, 控制投影手机进行投影演示, 也应该属于本专利的保护范围。 综上所述, 通过上述优选实施例以手机为例, 对移动终端投影演示的控 制方法进行说明, 可以解决相关技术中由于需要通过手机的按键或触摸屏来 控制投影内容的切换而导致投影设备的晃动、 偏移及用户体验差的问题, 增 强了系统的灵活性, 提高了用户体验。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布 在多个计算装置所组成的网络上, 可选地, 它们可以用计算装置可执行的程 序代码来实现, 从而, 可以将它们存储在存储装置中由计算装置来执行, 并 且在某些情况下, 可以以不同于此处的顺序执行所示出或描述的步骤, 或者 将它们分别制作成各个集成电路模块, 或者将它们中的多个模块或步骤制作 成单个集成电路模块来实现。 这样, 本发明不限制于任何特定的硬件和软件 结合。
