Description

一种确定激励图片的方法、系统及可读取存储介质 技术领域
本发明涉及人机交互技术领域，更具体地，涉及一种确定激励图片的方法、系统及可读取存储介质。
背景技术
脑-机接口不依赖于人的外周神经和肌肉，它将激励反馈解析为指令来控制外部设备，脑-机接口、操作者和被控对象共同形成脑控系统。脑控系统主要包含激励反馈诱发模块、激励反馈采集模块、激励反馈处理模块、控制模块以及反馈模块，通过各个模块的相互协作，脑控系统能够将激励反馈转化为控制指令，实现操作者对轮椅、机械臂、浏览器等外部设备的控制。
现有的视觉诱发界面设计通常基于P300 Speller范式，其中行列扫描模式是常用的激励模式。基于P300 Speller范式的视觉诱发界面的背景为纯色，背景之上显示一个n行n列的图片矩阵，各矩阵元素位置处的图片大小相同，内容为不同的英文字符，不同的英文字符激励对应触发不同的指令。在现有的激励模式下，界面运行时，此图片矩阵中的图片逐行逐列接连随机闪烁，此模式下的视觉诱发界面需各个图片组合均闪烁过一次时才能完成一次循环，在此循环之中，各张激励图片均需出现一次，使其能够确定目标激励图片。因此当图片矩阵较大，即指令较多时，这大大增加了指令输出的间隔，降低了脑控系统的反应速度。

具体实施方式
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
在本发明的说明书和权利要求书及上述附图中的描述的一些流程中，包含了按照特定顺序出现的多个操作，但是应该清楚了解，这些操作可以不按照其在本文中出现的顺序来执行或并行执行，仅仅是用于区分开各个不同的操作， 序号本身不代表任何的执行顺序。另外，这些流程可以包括更多或更少的操作，并且这些操作可以按顺序执行或并行执行。需要说明的是，本文中的“第一”、“第二”等描述，是用于区分不同的消息、设备、模块等，不代表先后顺序，也不限定“第一”和“第二”是不同的类型。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面先阐述本发明实施例中所需要提及名词。
激励图片，用于刺激用户产生激励特征信号的图片，其中，每个激励图片对应的激励内容不同。
屏蔽图片，用于使用户更加关注激励图片。在本发明实施例中，屏蔽图片可以为中间区域为白色圆形，其他区域为黑色的图片。
请参见图1，图1示出了一种电子设备100的结构框图。作为一种实施方式，所述电子设备可以为个人电脑(personal computer，PC)、平板电脑、智能手机等终端。该电子设备可以作为本实施例中的激励反馈诱发设备。
如图1所示，电子设备100包括一个或多个(图中仅示出一个)处理器111、存储控制器112、存储器113、外设接口114、显示单元115等。这些组件通过一条或多条通讯总线/信号线116相互通讯。
存储器113可用于存储软件程序以及模块，如本发明实施例中的确定激励图片的方法对应的程序指令/模块，处理器111通过运行存储在存储器113内的软件程序以及模块，从而执行各种功能应用以及数据处理，如本发明实施例提供的确定激励图片的方法。
存储器113可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。处理器111以及其他可能的组件对存储器113的访问可在存储控制器112的控制下进行。
外设接口114将各种输入/输出装置耦合至处理器111以及存储器113。在一些实施例中，外设接口114，处理器111以及存储控制器112可以在单个芯片中实现。在其他一些实例中，他们可以分别由独立的芯片实现。
显示单元115用于给用户提供一个显示界面。具体地，显示界面115向用户显示图像输出，这些图像输出的内容可包括文字、图形、视频及其任意组合。
可以理解，图1所示的结构仅为示意，电子设备100还可包括比图1中所示更多或者更少的组件，或者具有与图1所示不同的配置。图1中所示的各组件可以采用硬件、软件或其组合实现。
请参阅图2，图2为本发明实施例提供的一种确定激励图片的系统100，该系统100包括激励反馈诱发设备110、脑电信号采集设备120以及与所述脑电信号采集设备120耦合的激励反馈处理设备130。其中，激励反馈诱发设备110用于显示激励图片。脑电信号采集设备120用于佩戴到用户的头部采集用户的激励反馈。激励反馈处理设备130用于对用户的激励反馈进行处理，以提取出激励特征信号。
具体的，激励反馈诱发设备110被配置为显示视觉诱发界面，视觉诱发界面包括多个图片显示区域，每个图片显示区域被配置为显示不同的激励图片。其中，多个图片显示区域可以按照矩阵的方式排列。
在设置好所需的激励图片后，可以给每个激励图片设置一个图片序号，再基于每个激励图片的各自的图片序号，设置各自的二进制编码。例如，当设定的激励图片有8个时，可以给这8个激励图片分别编号为0、1、2、 3、4、5、6和7，则对应的二进制编码为000、001、010、011、100、101、110以及111。需要说明的是，在设定二进制编码的位数时，可以根据所需的指令数来确定。例如，上述设定的激励图片有8个，则对应的控制指令也为8个，而2的三次方为8，则当有8个控制指令时，设置3位的二进制编码即可实现8个控制指令均可以对应不同的3位二进制编码。相应的，当设置的控制指令有9个时，可以基于2的四次方为16，则四位的二进制编码可以实现9个控制指令。则可以给9个激励图片分别编号为0、1、2、3、4、5、6、7和8，则对应的二进制编码为0000、0001、0010、0011、0100、0101、0110、0111以及1000。
需要说明的是，上述激励图片以及对应的图片编号以及二进制编码可以由激励反馈诱发设备110预先计算好后存储在本地。当需要使用时，直接本地读取。此外，也可以预先存储在网络，而在需要使用时，从网络请求。
在激励图片的显示过程中，如图3所示，激励反馈诱发设备110可以先在视觉诱发界面全部显示屏蔽图片的界面，在显示预设时间后的屏蔽图片后，如图4所示，激励反馈诱发设备110根据每个激励图片的二进制编码，依次控制视觉诱发界面显示多组激励图片，且每次显示同一组的激励图片。其中，在图4中，含有箭头的图片为激励图片。
需要说明的是，在设定好激励图片以及激励图片对应的图片序号以及二进制编码后，在本实施例中，激励反馈诱发设备110可以根据每个激励图片对应的二进制编码的每个编码位的值设定分组，其中，同一组激励图片对应的二进制编码中的某同一编码位的值相同。例如，在上述8个激励图片的实例中，可以将二进制编码中从右向左的第一编码位均为1的001、 011、101以及111设置为第一组，将二进制编码中第二编码位均为1的010、011、110以及111设置为第二组，将二进制编码中第三编码位均为1的100、101、110以及111设置为第三组。则可以在视觉诱发界面显示第一组、第二组以及第三组的激励图片。其中，第一组、第二组以及第三组的激励图片的显示顺序可以有多种方式，可以依次显示，也可以先把三组随机打乱顺序后，按调整后的顺序依次显示。
需要说明的是，当激励图片有9个，即控制指令由9个时，设定分组的方式与上述方式相同，此处不再细述。
在视觉诱发界面显示激励图片的过程中，还需要采集用户的激励反馈，则所述脑电信号采集设备120，被配置为佩戴于用户头部，获取激励反馈诱发设备110依次控制所述视觉诱发界面显示多组激励图片时的每组激励图片对应的激励反馈，每组激励图片对应的所述激励反馈用于表征用户是否在关注该组内的激励图片。
需要说明的是，为了适应不同头部尺寸用户，脑电信号采集设备120可以设置不同的尺寸。作为一种方式，脑电信号采集设备120包括相互耦合的脑电帽和脑电采集器，脑电帽包括多个支架，各支架的终端携带用于检测电位信号的电极。作为一种方式，脑电采集器有多种大小的采集频率，例如200Hz、500Hz以及1000Hz等。而且脑电采集器在采集过程中能够同时采集多个电极通道的数据，并将接收的数据传输至脑电信号处理设备进行后续处理。需要说明的是，上述脑电采集器的采集频率只是示例性的，只要能够实现有效的脑电采集的采集频率均在本发明的保护范围内。
激励反馈处理设备130被配置为基于每组激励图片对应的激励反馈计算得到用户所关注的激励图片的二进制编码，以确定用户所关注的激励图 片。
在激励反馈处理设备130得到用户所关注的激励图片的二进制编码过程中，激励反馈处理设备130可以先生成与所述激励图片对应的二进制编码的编码位数相同的初始二进制编码；将初始二进制编码中的目标位设置为1，其中目标位为表征有激励特征信号的激励反馈所对应的同一组的激励图片对应的二进制编码中具有相同值的编码位。将初始二进制编码中除了目标位之外的其他编码位设置为0，以得到用户所关注的激励图片的二进制编码；根据用户所关注的激励图片的二进制编码，得到用户所关注激励图片的图片序号。
例如，若视觉诱发界面在显示第一组激励图片的过程中，所采集的激励反馈表征有激励特征信号，而在显示第二组激励图片和第三组激励图片的过程中，所采集的激励反馈表征没有激励特征信号，则用户所关注的激励图片的二进制编码为001，即图片序号为1的激励图片。
可以理解，在获取到激励特征信号后，激励反馈处理设备130可以将所述激励特征信号进行数据标准化处理以获得特征样本；采用预设的模式识别规则对所述特征样本进行训练，以得到训练参数；将训练参数与所述用户所关注的激励图片以及该激励图片所对应的控制指令对应存储，以便在指令识别阶段将所述训练参数与采集到待识别的激励特征信号对应的特征样本进行识别匹配，以识别用户所期望触发的控制指令。
需要说明的是，作为一种方式，在本实施例中所述激励特征信号为检测到用户关注激励图片触发的激励事件发生时前后2s内的所采集到的特征信号。而激励特征信号为P300激励特征信号。
本发明实施例提供的一种确定激励图片系统，通过依次控制所述视觉诱 发界面显示多组所述激励图片，且每次显示同一组的所述激励图片，其中，同一组激励图片对应的二进制编码中的某同一编码位的值相同，并且在显示过程中获取依次控制所述视觉诱发界面显示多组激励图片时的每组激励图片对应的激励反馈，基于所述每组激励图片对应的激励反馈计算得到用户所关注的激励图片的二进制编码，以确定用户所关注的激励图片，从而在确定用户所关注的激励图片过程中，不需要各张激励图片均出现过一次时才能完成一次循环，减少了一次循环中闪烁的激励图片组合的个数，降低了指令输出的间隔，提升了脑控系统的反应速度。

需要说明的是，所述激励特征信号为检测到用户关注激励图片触发的激励事件发生时前后2s内的所采集到的特征信号。激励特征信号为P300激励特征信号。

需要说明的是，在本实施例中的激励图片的数量以及控制指令的数量只是示例性的，可以根据实际情况自由设定，而在具体设定控制指令的数量以及激励图片的数量时。
