Description

一种可配套智能终端的眼球追踪装置 技术领域
本发明属于眼球追踪技术领域，具体涉及一种可配套智能终端的眼球追踪装置。
背景技术
目前，公知的眼球追踪***主要包括眼球追踪装置和显示设备；其中，眼球追踪装置的核心设备为红外光源和图像采集设备；其主要工作原理为：采用红外光源发射出的红外线对眼睛作近距照射，此处，因人眼对红外光无光感，因此红外线并不会影响人的正常视觉效果；然后，由于眼睛中虹膜、瞳孔和巩膜对红外线的折反射率存在差异，因此，通过图像采集设备不断拍摄人眼图像，通过对人眼图像进行图像分析处理，可生成眼动轨迹，并通过显示设备显示眼动轨迹，实现人眼视线跟踪。
上述眼球追踪***虽然具有***成本较低、使用方便以及视线跟踪精度高等优点，但是，眼球追踪装置多通过支架固定在显示设备的附近，并通过数据线实现眼球追踪装置和显示设备的通信。虽然眼球追踪装置不受显示设备的限制，但是，眼球追踪装置和显示设备采用分体式形式，具有占用空间大、携带不方便、组装繁琐、成本高、眼球追踪装置和显示设备之间相对位置易变动等问题，从而限制了眼球追踪***的广泛推广使用。

壳体11设置有夹持机构15，夹持机构15可调节，用于适应固定不同尺寸的智能终端，例如，夹持机构15为夹持外壳或夹持槽或夹持支撑板和/或接口，眼球追踪装置10通过夹持机构15夹持固定在智能终端30的显示屏31以外的表面；并且，眼球追踪装置10通过连接器件与具有显示屏31的智能终端30之间通信连接；具体地，如图6所示，夹持机构15可采用插接结构15-1来固定智能终端，通过插接结构的凸起***到手机端的凹槽中以将眼球追踪装置10夹持固定在智能终端30的显示屏31以外的表面。
图像传感器模组12和近红外光源13的组数均至少有一组，安装在壳体11***；并且，图像传感器模组12的中心光轴方向以及近红外光源13的光束中心方向与智能终端30的显示屏31所在的平面呈一定夹角安装。作为一种优选方式，图像传感器模组12的中心光轴方向以及近红外光源13的光束中心方向与智能终端30的显示屏31所在的平面各方向的安装夹角数值小于+55°且大于-55°。
对于本发明提供的眼球追踪装置，其使用方法为：
首先，眼球追踪装置10通过夹持机构15夹持固定在智能终端30的显示屏31以外的表面，使眼球追踪装置10和智能终端30之间相对位置固定不动。
由于眼球追踪装置10自身安装有图像传感器模组12和近红外光源13，并且，眼球追踪装置10与智能终端30可通信，因此，近红外光源13照射眼睛，通过图像传感器模组12采集到人眼图像，最终对人眼图像进行分析，实现人眼视线跟踪。
可见，本发明提供的眼球追踪装置，既具有对智能终端固定作用，又能够实现传统的人眼视线跟踪的功能，具有占用空间小、携带方便、组装简单、成本低、眼球追踪装置和具有显示屏的智能终端之间相对位置固定等优点。
在上述结构的基础之上，实际应用中，还可对眼球追踪装置进行多方面的改进，以下对相关改进进行详细介绍，但是，需要强调的是，以下改进并不用于限制本发明的保护范围：
需要说明的是，眼球追踪装置和具有显示屏的智能终端之间的连接固定方式，可采用各类形式，为方便对本发明进行理解，本发明附图共介绍了4种连接固定方式。
具体的，图1-图5为眼球追踪装置和智能终端采用第1种连接固定方式的相关示意图；图6-图7为眼球追踪装置和智能终端采用第2种连接固定方式的相关示意图；图8-图11为眼球追踪装置和智能终端采用第3种连接固定方式的相关示意图；图12-图15为眼球追踪装置和智能终端采用第4种连接固定方式的相关示意图。当然，实际应用中，也可采用其他连接固定方式，本发明对此并不限制。
在结合图1-图16的基础上，本发明改进如下：
改进1：为提高图像传感器模组12对人眼图像的采集精度，图像传感器模组12的设置数量可以为多个，并且，对于多个图像传感器模组12，至少存在一个近红外摄像头；和/或至少存在一个自动对焦摄像头，自动对焦摄像头优选为相位自动对焦摄像头。
另外，图像传感器模组12的镜片外部还可以设置有红外滤光片，红外滤光片用于过滤掉可见光，消除可见光对所采集图像的影响，进一步提高图像传感器模组对人眼图像的采集精度。
改进2：
每个近红外光源13由至少一个红外点光源组成，相邻红外点光源的距离不超过20毫米。并且，根据实际需求，灵活调整近红外光源的设置数量和设置位置，实现近红外光源对人眼的充分照射。
例如：
近红外光源13的设置数量为1组，靠近图像传感器模组12设置；
或者
近红外光源13的设置数量为2组，安装于图像传感器模组12的左右两侧；
或者
近红外光源13的设置数量为2组，分别安装在壳体11的上下两侧；
或者

或者
近红外光源13的设置数量为4组，分别安装在壳体11的四个角位置；
或者
近红外光源13的设置数量为5组，其中一个靠近图像传感器模组12设置；另外四个分别安装在壳体11的四个角位置。
改进3：
还包括集成电路板17，集成电路板17上设置有主控芯片16，主控芯片16分别与图像传感器模组12和近红外光源13连接。
改进4：
连接器件为接口14-1和/或天线14-2，从而实现眼球追踪装置和智能终端之间的通信连接。
另外，当连接器件为接口14-1时，例如，为Micro usb接口和/或Type-c usb接口和/或闪电接口和/或HDMI接口和/或以太网口和/或3.5mm耳机接口，连接器件同时具有夹持机构15的固定功能。
天线14-2可采用蓝牙通讯模块和/或WIFI通讯模块和/或红外通讯模块。
改进5：
主控芯片16的第1端口与近红外光源13连接；主控芯片16的第2端口与图像传感器模组12连接；
主控芯片16的第3端口通过接口14-1与智能终端30连接；和/或主控芯片16的第4端口通过天线14-2与智能终端30连接。
改进6：
眼球追踪装置还包括供电电源。供电电源为内置供电电池18和/或无线充电模块19；其中，供电电池18与主控芯片16的第5端口连接；无线充电模块19与主控芯片16的第6端口连接。
实际应用中，无线充电模块19可采用电磁感应换能模块和/或电场换能模块和/或磁共振换能模块和/或超声波换能模块和/或电磁波换能模块。
改进7：
壳体11还设置有用于与外部设备通信和供电的第1通信供电接口20；第1通信供电接口20与主控芯片16连接。其中，第1通信供电接口20可采用USB母口或DC接口。通过第1通信供电接口20，实现眼球追踪装置与外部设备的通信和/或供电。
改进8：
眼球追踪装置还设置有控制按钮，控制按钮为实体按钮23和/或类比遥杆24和/或控制开关21和/或触摸板22。
综上所述，本发明提供的可配套智能终端的眼球追踪装置具有以下优点：
既具有对智能终端固定作用，又能够实现传统的人眼视线跟踪的功能，具有占用空间小、携带方便、组装简单、成本低、眼球追踪装置和具有显示设备的智能终端之间相对位置固定、功能多样等优点。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视本发明的保护范围。
