Description

盲人佩戴品
技术领域
本发明属于导航设备技术领域，具体涉及一种盲人佩戴品。
背景技术
盲人由于其固有的视觉缺陷，导致在日常生活中会存在诸多不便。尤其是路上的障碍物和行驶在路上的车辆对盲人出行带来的危险隐患，使得盲人的日常出行不便。
目前，盲人出行多数依赖拐杖探索前方的路面状况，当然也有少数盲人依赖导盲犬陪伴出行。但是发明人发现现有技术中至少存在如下问题：拐杖的功能有限不能很好的满足目前复杂的路面状况；在发生突发情况时，导盲犬很有可能受到惊吓，以威胁到周边行人的安全。
发明内容
本发明所要解决的技术问题包括，针对现有的盲人出行安全问题，提供一种具有可以准确输入盲人行走路径的导航设备的盲人佩戴品。

具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明作进一步详细描述。
本发明提供了一种盲人佩戴品，其包括：第一佩戴组件，在所述第一佩戴组件上设置有语音识别单元、中央处理单元、GPS单元、语音输出单元，以及盲文点字显示单元；其中，所述语音识别单元，用于接收语音信息；所述盲文点字显示单元，用于将接收到的所述语音信息生成盲文信息；经用户(包括指视力较低的用户或盲人用户)确认所述盲文信息与所述语音信息相匹配后，将所述盲文信息传递给所述中央处理单元；所述中央处理单元中存储有电子地图数据库，用于根据所述盲文信息在电子地图数据库中搜索出行走路径；所述GPS单元，用于对所述行走路径进行实时定位，并将定位出的位置信息反馈给所述中央处理单元；所述语音输出单元，用于根据所述GPS单元反馈给所述中央处理单元的所述位置信息进行导航。
其中，上述的第一佩戴组件可以为手镯、脚镯、发带、帽子等可以佩戴的装饰品，该种佩戴品特别适用于盲人。而且，在该佩戴品具有为盲人导航指路的功能，使得盲人的出行更加方便和安全。特别的是，该佩戴品上具有盲文点字显示单元，当环境噪音影响语音输入的准确时，用户通过盲文电子显示单元可以对语音信息输入的结果进行验证，确保用户语音输入的路线的准确性。
本发明的盲人佩戴品的具体实现方式见下述实施例。
实施例1：
如图1所示，本实施例提供一种盲人佩戴品，该盲人佩戴品至少具有第一佩戴组件1，该第一佩戴组件1为手镯，用户可将手镯佩戴在手腕上，不仅美观，而且还具有导航指路的功能。
具体的，如图2和图3所示，在手镯上设置有语音识别单元、中央处理单元、GPS单元、语音输出单元，以及盲文点字显示单元。其中，当用户(包括指视力较低的用户或盲人用户)发出将要到达目的地的语音信息，与此同时，语音识别单元接收将该语音信息(该语音信息可能是用户所发出的语音信息，也就是目的地的名称信息，也可能是当时外界环境的杂音，还可能是用户所发出的语音信息和外界环境的杂音的混合)，盲文点字显示单元将接收到的语音信息生成盲文信息；用户通过手指触摸所生成的盲文信息，以确定语音输入的目的地的信息是否正确，当所述盲文信息与用户所发出的语音信息，即将要到达目的地的名称信息相匹配时，将所述盲文信息传递给所述中央处理单元；中央处理单元根据其内存储的电子地图数据库搜索出行走路径；手镯中的GPS单元(卫星定位单元)对用户的行走路径进行实时定位，并反馈给中央处理单元，通过语音输出单元对用户的行走路径进行实时的播报。
优选地，在手镯中还设置有图像采集单元和第一震动单元，所述图像采集单元，用于采集路面上是否存在障碍物的信息；当采集到路面上存在障碍物的信息时，将障碍物的信息传递给所述中央处理单元；所述第一震动单元，用于当所述中央处理单元接收到障碍物的信息后，发出震动信号，以提醒用户注意路面上存在障碍物。
由于本实施例的手镯中设置有图像采集单元，其可以实时采集路面状况，并通过第一震动单元提醒用户，从而保证了盲人出行的安全性。
其中，当GPS单元定位出的位置信息为拐弯处时，上述的第一震动单元还用于发出震动信号，以提醒用户注意拐弯方向。例如，震动一下表示向左拐，震动两下表示向右拐。当然了也可以通过其他的震动形式，以提醒用户，在此不详细描述。当然第一震动单元提醒用户拐弯方向转弯方向时的震动次数或者震动方式，是与上述提醒用户前方路面状况时是不同的。
其中，上述的图像采集单元可以是红外传感器，当然也可以是摄像头等能够用于采集图像的装置。上述的第一震动单元为震动马达。
优选地，本实施例的手镯还包括陀螺仪和报警单元；所述陀螺仪，用于监测所述盲人佩戴品的佩戴者是否发生跌倒；所述报警单元，用于当用户跌倒时，发出报警信号，并将该信号发送给一通讯终端，从而保证用户在发生意外情况时，可以及时通知他人，以做到对盲人出行安全的实时监控，确保盲人安全出行。其中，通讯终端通常为手机。
需要说明的是，报警单元所发出的信号可以是通讯信号，此时还通讯信号可以直接发送给通讯终端，也可以发出一个报警信号指令给手镯中预先设置的通信单元，通过通讯单元发出信号给通讯终端。
在本实施例中盲文点字显示单元可以采用传统的机械式电子显示器或电子式薄膜型盲文显示器。具体的，机械式电子显示器，由一个有8个凸触点的盲文单元和2个方向按键和1个确认键。凸现点阵所使用的机械原理属于压电效应。对压电单位施加电压时，其体积会增大，再通过杠杆原理，实现凸现的效果。方向键和确认键用来对所读的文本作上下左右的翻动和最终确认。当输入语音信息的地址语音通过语音识别单元识别后，盲文点字显示单元自动把识别出来的语音信息在点字显示器显示，用户触摸电子显示器进行判断，当显示的文字和语音输入相同时，点击确认键，自动显示后面一个盲文，当所有盲文判断正确完成后，将盲文信息传递给中央处理单元。
电子式薄膜型盲文显示器通过采用可触觉反馈的电子触摸屏幕，实现在屏幕上的凹凸和突起，形成盲文，在电子式薄膜型盲文显示器上还包括一个LCD平板屏幕、多个力传感器和一个可来回移动的机械臂。屏幕使用触觉反馈技术，通过阻力和振动给用户提供反馈，使用户能够清楚地感觉到屏幕中所显示的文字。触摸判断正确完成后，将盲文信息传递给中央处理单元。
在本实施例中仅仅是盲人佩戴品的第一佩戴组件1为手镯为例进行说明的，应当理解的是第一佩戴组件1同样可以采用脚镯、发带、帽子等其他佩戴组件。
实施例2：
本实施例提供一种盲人佩戴品，不仅包括实施例1中第一佩戴组件，还包括两个第二佩戴组件，且两个第二佩戴组件与所述第一佩戴组件通讯连接。也就是说在第一佩戴组件和两个第二佩戴组件中均设置有通讯单元，从而保证第佩戴组件和第一佩戴组件通讯连接。在本实施例中同样以第一佩戴组件为手镯为例进行说明，应当理解的是第一佩戴组件同样可以采用脚镯、发带、帽子等其他佩戴组件。本实施例中的两个第二佩戴组件可以为两个脚镯。
其中，在本实施例的两个脚镯中均设置有第二震动单元；所述第二震动单元，用于当所述GPS单元定位出的位置信息为拐弯处，发出震动信号，以提醒用户注意拐弯方向，且两个所述第二震动单元发出的震动信号代表的拐弯方向不同。其中，上述的二震动单元为震动马达。
用户佩戴本实施例中的脚镯后，即使在嘈杂环境中，也可以通过第二震动单元的震动，将该震动信号出递给用户的左脚或者右脚，以提醒用户拐弯的方向，以免用户由于在嘈杂环境中使用语音导航获取错误的导航信息，而导致迷路的现象。
应当理解的是，本实施例中第二佩戴组件也可以为手镯。也就是说通过左、右手感应震动信号，以实现通知用户的拐弯方向。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
