蓝牙AOA定位技术
蓝牙AOA定位技术通过信号的角度信息进行定位估算，控制装置(发射端)利用单一天线发射寻向讯号，显示设备(接收端)内置天线阵列，当信号通过时，因阵列中接收到距离不同而产生相位差异，提高定位的精确度。
蓝牙5.0协议中规定了蓝牙天线切换的补偿时间为固定的2微秒，在补偿时间内采集的蓝牙信号的相位值全部会被过滤掉，这样会导致计算的相位值不准从而导致定位的准确性降低。
本申请一些实施例提供了一种基于蓝牙的定位方法及装置，不再过滤固定的补偿时间内的相位值，而是根据相位值的变化情况确定需要过滤的相位值，减少相位值的浪费，提升定位的准确性。
下面，对于本申请一些实施例提供的基于蓝牙的定位方法进行介绍。该方法可以由显示设备来执行，或者也可以由显示设备中的处理器来执行，后续以由显示设备执行为例进行介绍。显示设备的内部结构可以采用上述图3示出的显示设备200的硬件配置。天线组包括的各个天线可以位于显示设备的外部，且与显示设备相连接，例如天线组可以位于显示设备上方边缘，贴附于显示设备的非金属材质的外壳上。天线组包括的各个天线可以位于显示设备内部。天线组包括的多个天线中一部分位于显示设备外部，另一部分位于显示设备内部。不同的天线组之间可以保持一定的距离，以保证定位的准确性。天线组中包含的天线之间的距离不能大于蓝牙信号的波长，比如，蓝牙信号的波长为0.125m，任意两根天线之间的距离不能超过0.125米(m)。作为一种示例，显示设备的外壳可以为非金属材质；显示设备包含两个天线组、每个天线组中包含两根天线；两组天线位于显示设备上方边缘位置，两组天线之间的距离为显示设备的宽。在一些实施例中，显示设备的外壳可以为金属，比如铝合金外壳。可以在设计显示设备时，将主板放置在显示设备后面，再加一个塑料(或者其他的非金属材料)后壳罩住该主板，那么也可以将天线贴附于该塑料后壳上。
本申请一些实施例提供了一种基于蓝牙AOA的定位方法，具体包括：
步骤1，显示设备通过至少两个天线组中的第一天线接收广播信号，检测广播信号的多个相位值。
其中，第一天线属于至少两个天线组中的第一天线组中的任一根天线，第一天线组为显示设备包括的至少两个天线组中的任一个天线组。广播信号来自于控制装置，例如蓝牙发射器，显示设备检测到的广播信号的多个相位值为在第一设定时长内检测到的多个相位值。
在一些实施例中，显示设备可以通过蓝牙组件包括的至少两个天线组在广播信道中扫描广播信号，根据广播信号中包括的设定标识确定该广播信号中包括的用于定位的固定频率扩展信号(Constant Tone Extension，CTE)。在一些实施例中，CTE可以包含在广播信号携带的广播数据包中，广播数据包的格式可以参见图7，其中包含的各项分别为：前导(Preamble)，广播数据包的包头；接入地址(Access Address)，用于指示广播信号的传输信道；协议数据单元(Protocol Data Unit，PDU)，包括广播信号的信号强度以及蓝牙发射器的标识等；循环冗余校验(Cyclic Redundancy Check，CRC)，用于校验PDU的数据的准确性；CTE，用于检测广播信号的相位值。
在一些实施例中，显示设备可以根据广播信号中包括的CTE确定天线的相位值。以一根天线(例如第一天线)的相位值的确定过程为例进行介绍：首先，显示设备可以获取第一天线接收的广播信号中包含的CTE；在一些实施例中，显示设备可以从CTE中采集同相正交(In-phase Quadrature，IQ) 数据，IQ数据中包括广播信号到达第一天线时的相位值和振幅信息。从而，显示设备可以获取第一天线对应的广播信号的相位值。后续为了便于描述，广播信号到达相应天线时的相位值或天线对应的广播信号的相位值可以简称为天线的相位值或天线对应的相位值。
由于广播信号是以波束的形式发射的，所以在第一设定时长内的不同时间点，第一天线接收到的广播信号的相位值是不相同的。
在一些实施例中，显示设备检测到的第一天线的多个相位值的取值范围可以为[-π，π]，并且显示设备检测到的第一天线的多个相位值可以随着检测时间的推移而顺序增大，即第一天线的多个相位值与检测时间成正比。
步骤2，显示设备通过第二天线接收广播信号，检测接收到的广播信号的多个相位值。
其中，第二天线为第一天线组中除第一天线之外的任一根天线，显示设备检测到的第二天线接收到的广播信号的多个相位值为在第二设定时长内检测到的。在一些实施例中，第一设定时长可以与第二设定时长相等。第二设定时长可以为第一设定时长之后且与第一设定时长相邻的一个时间段。
在一些实施例中，显示设备可以在达到第一设定时长之后，控制第一天线停止接收广播信号，并控制第二天线开始接收广播信号。在另一些实施例中，显示设备还可以在未达到第一设定时长时开始在第二设定时长内检测通过第二天线接收到的广播信号。在一些实施例中，显示设备可以通过设置定时器的方式来进行天线的切换，例如显示设备可以在开始通过第一天线接收广播信号时启动定时器，并设置定时器的定时时长为第一设定时长，然后在定时器超时时，切换为通过第二天线接收广播信号。在一些实施例中，显示设备还可以保存切换的时间点。在一些实施例中，当第一天线组中包括多根天线时，显示设备可以预先设定一个切换顺序，例如，切换顺序可以为从第一天线切换到第二天线再切换到第三天线等。
步骤3，显示设备对第二天线对应的多个相位值进行过滤得到经滤除第二天线的多个相位值。
在一些实施例中，显示设备可以滤除第二天线的多个相位值中满足设定条件的至少两个相位值得到经滤除第二天线的多个相位值。其中，满足设定条件的至少两个相位值与相位值的检测时间成反比。也就是说，显示设备滤除的至少两个相位值是连续检测到的，并且与检测时间成反比，即滤除的至少两个相位值是随着检测时间的增加依次减小的。在一些实施例中，滤除的至少两个相位值中任意两个连续检测到的两个相位值的差小于设定的阈值。
在一些实施例中，由于切换为新的天线接收蓝牙信号时，蓝牙信号需要一段稳定时间。也就是说，显示设备在切换到第二天线接收广播信号时，初始一段时间内接收到的广播信号是不稳定的，那么也就导致了显示设备在检测这段时间内接收到的广播信号的相位值是不可用的，后续为了便于描述，将该段时间称为补偿时间。已知正常情况下显示设备连续检测到的相位值是随着检测时间递增的，但是由于在补偿时间内接收到的蓝牙信号不稳定，导致在补偿时间内连续检测到的相位值是与检测时间成反比的。所以显示设备在检测第二天线的多个相位值之后，可以将连续检测到的与检测时间成反比的相位值过滤掉，也就是将补偿时间内接收到的广播信号对应的至少两个相位值过滤掉。
步骤4，显示设备根据第一天线的多个相位值与经滤除第二天线的多个相位值确定第一天线组的相位差。
在一些实施例中，第一天线组包括两根天线，分别为第一天线和第二天线。显示设备可以根据第一天线的多个相位值与第二天线的多个相位值的差值的平均值作为第一天线组的相位差。例如，可以参见图5，示出了第一天线在第一设定时长内的多个相位值以及第二天线在第二设定时长内的多个相位值，每一个点代表一个相位值。以其中的几个相位值为例介绍计算相位差的过程：显示设备检测出的第一天线的相位值与检测时间分别为：(t 1时刻：1/4π，t 2时刻：1/3π，t 3时刻：1/2π)，显示设备检测出的第二天线的相位值与检测时间分别为：(t 4时刻：1/2π，t 5时刻：7/12π，t 6时刻：3/4π)。显示设备可以计算t 4时刻与t 1时刻相位值的差值、t 5时刻与t 2时刻相位值的差值以及t 6时刻与t 3时刻相位值的差值，根据上述三个差值的平均值确定第一天线组的相位差。其中，t 4-t 1＝t 5-t 2＝t 6-t 3＝T，T为预设的检测周期，T可以与第一设定时长或者第二设定时长相等。上述举例中的第一天线的相位值的数量和第二天线的相位值的数量是相同的，当然，也可以有两根天线的相位值的数量不同的情况。当两根天线的相位值的数量不相同时，显示设备可以以相位值数量少的那根天线为准计算相位差。
在另一些实施例中，第一天线组包括的天线的数量大于2，显示设备可以采用上一实施例中的方法计算第一天线组中任意两根天线的相位值的差值，并将多个差值的平均值作为第一天线组的相位差
同理，显示设备可以进一步采用上述方法确定显示设备中包括的至少两个天线组中每个天线组的相位差。
步骤5，显示设备根据至少两个天线组各自的相位差确定发射广播信号的蓝牙发射器的位置。
本申请不再采用固定的补偿时间将检测补偿时间内接收到的蓝牙信号的相位值滤除，而是通过检测到的相位值的变化情况进行相位值的滤除。由此可以减少数据的浪费，获取更多的相位值计算出的相位差也会更加准确，从而提升定位的准确性。
在一些实施例中，显示设备在根据每个天线组的相位差确定蓝牙发射器的位置时，可以首先根据每个天线组的相位差确定每个天线组的到达角。再根据每个天线组的到达角确认蓝牙发射器的位 置。
在一些实施例中，显示设备在通过至少两组天线接收到广播信号之后，还可以进一步确定接收到的广播信号的波长。由于在2.4G无线技术中广播信号的波长是固定的，所以每一根天线接收到的来自同一个蓝牙发射器的广播信号的波长相同。在一些实施例中，显示设备在获取每一个天线组对应的到达角时，还可以根据广播信号的波长和每一个天线组的相位差共同确定到达角。在一些实施例中，以第一天线组为例，第一天线组包含两根天线，第一天线组对应的到达角可以通过如下公式(1)确定：
Figure PCTCN2022095742-appb-000001
其中，θ为第一天线组对应的到达角，
Figure PCTCN2022095742-appb-000002
为第一天线组对应的相位差，λ为广播信号的波长，d为所述第一天线组包括的两根天线之间的距离。
在一些实施例中，显示设备在确定各组天线的到达角之后，可以进一步确定蓝牙发射器的位置。在一些实施例中，以显示设备包含两个天线组(后续分别简称为第一天线组和第二天线组)为例，蓝牙发射器的位置可以通过如下公式(2)-公式(3)确定：
Figure PCTCN2022095742-appb-000003
Figure PCTCN2022095742-appb-000004
其中，θ 1为第一天线组对应的到达角，θ 2为第二天线组对应的到达角，(x，y)为蓝牙发射器的位置，(x 1，y 1)为第一天线组的位置，(x 2，y 2)为第二天线组的位置。
在一些实施例中，当显示设备包含两个天线组，且分别位于显示设备的两侧时，显示设备在进行计算蓝牙发射器的位置之前，可以首先获取显示设备的宽度，从而在确定一个天线组的位置的情况下，就可以计算出另外一个天线组的位置。并且，由于相关技术中，天线组之间的距离都是固定的，所以相关的算法都是基于固定的距离进行计算的。而本申请中天线组是位于显示设备的两侧的，所以不同的显示设备可能会存在不同的天线组的距离，所以相关的算法并不适用于本申请的应用场景。因此本申请会在计算蓝牙发射器的位置之前首先获取天线组之间的距离，解决了现有算法不适用的问题。
以上介绍了显示设备根据每根天线的相位值确定蓝牙发射器的位置的过程，在另外一些实施方式中，蓝牙发射器在发射广播信号时，是以电磁波束的形式发射的，一部分电磁波束可能会直接到达天线，也可能会存在另一部分电磁波束经过墙壁反射后到达天线，这样就会导致显示设备在计算一个天线组接收的同一个蓝牙发射器发射出的广播信号的到达角时，出现两个或者多个到达角，可能会针对同一个蓝牙发射器定位出两个或者多个位置，需要从这两个或多个位置中确定蓝牙发射器的真实位置。下面以显示设备接收到广播信号包括两个来自同一蓝牙发射器的蓝牙信号为例介绍确定蓝牙发射器真实位置的过程，为了便于描述，后续分别将这两个蓝牙信号称为第一蓝牙信号和第二蓝牙信号。作为一种示例，可以参见图6，其中示出了蓝牙发射器发射的蓝牙信号有直接到达显示设备的，也有经过墙壁反射后到达显示设备的。这就会导致显示设备会接收到来自蓝牙发射器的两个蓝牙信号：第一蓝牙信号和第二蓝牙信号。显示设备在根据这两个蓝牙信号进行定位时也同样会确定两个位置，也就是图6中示出的位置P_A和位置P_B，可以看出位置P_A才是蓝牙发射器的真正位置，那么也就需要显示设备将位置P_B过滤掉，确定蓝牙发射器的真正位置。如下展开介绍过滤方法：
在一些实施例中，显示设备在接收到第一蓝牙信号和第二蓝牙信号时，可以根据第一蓝牙信号和第二蓝牙信号中携带的蓝牙发射器的标识确定第一蓝牙信号和第二蓝牙信号来自于同一个蓝牙发射器。其中，蓝牙发射器的标识可以是蓝牙发射器的MAC地址或者蓝牙发射器的名称等。在一些实施例中，显示设备可以进行检测第一蓝牙信号和第二蓝牙信号的信号强度(Received Signal Strength Indication，RSSI)，并可以在确定第二蓝牙信号的信号强度小于第一蓝牙信号的信号强度时滤除第二蓝牙信号，根据第一蓝牙信号确定蓝牙发射器的位置即为蓝牙发射器的真正位置。在一些实施例中，显示设备还可以计算第一蓝牙信号携带的蓝牙数据包中的信号强度与测量到的第一蓝牙信号的信号强度的差值，以及计算第二蓝牙信号携带的蓝牙数据包中的信号强度与测量到的第二蓝牙信号的信号强度的差值，并对比两个差值的大小，其中，由于第一蓝牙信号和第二蓝牙信号实质来自于同一蓝牙信号所以两者的蓝牙数据包中记录的信号强度相同。当确定第二蓝牙信号对应的差值大于第一蓝牙信号对应的差值时，将第二蓝牙信号滤除，根据第一蓝牙信号对蓝牙发射器进行定位。
在另一些实施例中，显示设备首先确定第一蓝牙信号和第二蓝牙信号来自于同一个蓝牙发射器，具体参见情况一中的描述，在此不再赘述。当第一蓝牙信号和第二蓝牙信号的信号强度相等(例如，因蓝牙发射器距离墙体较近等因素以致第一蓝牙信号和第二蓝牙信号的强度无实质区别)时，显示设备可以分别计算第一蓝牙信号对应的第一相位差以及第二蓝牙信号对应的第二相位差，并根据第一相位差计算第一到达角以及根据第二相位差计算第二到达角。显示设备确定第一到达角和第二到达角之后，可以进行判断两个到达角是否处于滤除范围，即不能用于定位的角度范围。在图6所示的场景中，滤除范围即为位于显示设备后方的角度的范围。在一些实施例中，滤除范围可以是预先设定的，例如可以预先设定0°-180°作为显示设备前方的角度范围，将180°-360°作为显示设备后方的角度范围，即滤除范围。当显示设备确定第二到达角位于滤除范围时，将第二蓝牙信号滤除，根据第一到达角确定蓝牙发射器的位置。
基于上述多个实施例，显示设备在进行定位之前，先根据信号强度或者根据信号到达角将不能用于定位的信号滤除，从而能够更加准确地进行定位，防止定位错误的情况发生。
上述两种情况均是以显示设备接收来自同一个蓝牙发射器的两个蓝牙信号为例进行介绍的，如果显示设备接收到来自同一个蓝牙发射器的蓝牙信号的数量超过2时，也可以采用上述的方法确定蓝牙发射器的真正位置。
下面，参见图8，为本申请一些实施例的一个具体的定位方法流程，包括：
S701，显示设备通过第一天线组的第一天线和第二天线以及第二天线组的第三天线和第四天线接收来自蓝牙发射器的第一蓝牙信号和第二蓝牙信号。
在一些实施例中，显示设备可以通过第一蓝牙信号和第二蓝牙信号中携带的蓝牙发射器的标识确定第一蓝牙信号和第二蓝牙信号来自同一蓝牙发射器。
S702，显示设备判断第一蓝牙信号和第二蓝牙信号的信号强度是否相等。
若不相等，则进入第一过程，第一过程包括步骤S703、S704、S705、以及S707。
若相等，则进入第二过程，第二过程包括步骤S706以及S707。
S703，显示设备在确定第二蓝牙信号的信号强度小于第一蓝牙信号的信号强度时，将第二蓝牙信号过滤掉。
S704，显示设备分别检测第一天线、第二天线、第三天线和第四天线对应的第一蓝牙信号的多个相位值。
在一些实施例中，第二天线为第一天线组中后切换的天线(即在第一设定时长内显示设备先通过第一天线接收第一蓝牙信号，在第一设定时长后的第二设定时长内切换为通过第二天线接收蓝牙信号)，显示设备在检测第二天线的多个相位值之后，可以将其中满足设定条件的相位值滤除，具体地滤出过程可以参见上述基于蓝牙AOA的定位方法中的步骤3的介绍。
同理，若第四天线为第二天线组中后切换的天线，显示设备可以在检测第四天线的多个相位值后，将其中满足设定条件的相位值滤除。
S705，显示设备分别计算第一天线组和第二天线组针对第一蓝牙信号的到达角。
S706，显示设备分别计算第一蓝牙信号的到达角和第二蓝牙信号的到达角，在确定第二蓝牙信号的到达角属于过滤范围时，将第二蓝牙信号过滤掉。
在一些实施例中，显示设备可以针对第一天线组分别计算第一蓝牙信号和第二蓝牙信号的到达角，以及针对第二天线组分别计算第一蓝牙信号和第二蓝牙信号的到达角。显示设备可以在确定第一天线组和第二天线组对应的第二蓝牙信号的到达角都属于过滤时，将第二蓝牙信号过滤掉。
S707，显示设备根据第一天线组和第二天线组分别确定的到达角来确定蓝牙发射器的位置。
根据本申请一些实施例的蓝牙AOA定位技术可以应用于对显示设备的控制，包括但不限于下述的实施方式。
(1)与显示设备和控制装置的蓝牙配对关联的实施方式
相关技术中，显示设备可以通过蓝牙组件中包括的天线接收蓝牙控制设备发送的广播信号，然后在广播信道上发送请求连接信息，并根据广播信号的指示确定用于承载数据的数据信道，在确定的数据信道上与蓝牙控制设备建立密钥，与蓝牙控制设备通过密钥进行蓝牙连接。但是如果空间中存在多个显示设备都接收到了来自蓝牙控制设备的广播信号，多个显示设备就都会向该蓝牙控制设备发送请求连接信息，如果蓝牙控制设备需要连接多个显示设备中的第二显示设备，但是多个显示设备中的第一显示设备的请求连接消息先到达了蓝牙控制设备，则蓝牙控制设备就会与第一显示设备建立连接，由于蓝牙控制设备实际要连接的是第二显示设备，所以连接错误。并且用户无法得知蓝牙控制设备具体连接的是哪一个显示设备，只知道蓝牙控制设备处于连接状态(以遥控器为例，遥控器连接到显示设备之后可以亮起指示灯)。
本申请一些实施例提供了一种蓝牙连接的方法及显示设备，当存在多个显示设备对应一个蓝牙控制设备的场景，或者存在多个蓝牙控制设备对应一个显示设备的场景，显示设备会在进行建立蓝牙连接之前对蓝牙控制设备进行定位，根据定位的结果建立蓝牙连接，避免连接错误或者连接失败的问题。为了便于描述，后续以蓝牙控制设备为控制装置100为例描述本申请提供的方案。
对本申请一些实施例提出的蓝牙连接的方法进行介绍，该方法可以应用于显示设备，也可以应用于显示设备包括的处理器，后续均以应用于显示设备为例进行介绍。参见图9，为本申请一些实施例的一种蓝牙连接的流程，具体包括：
S1101，显示设备通过蓝牙组件接收来自控制装置的广播信号。
其中，蓝牙组件可以包括用于接收和发送蓝牙信号的至少两个天线组。
在一些实施例中，显示设备可以通过蓝牙组件包括的至少两个天线组在广播信道中扫描广播信号，根据广播信号中包括的设定标识确定该广播信号中包括用于定位的CTE。在一些实施例中，CTE可以包含在广播信号携带的广播数据包中，广播数据包的格式可以参见图7及其说明。
S1102，显示设备根据接收到的广播信号中包括的CTE，分别确定每个天线组对应的广播信号的到达角。
在一些实施例中，显示设备可以根据广播信号中包括的CTE确定每根天线的相位值，在根据每根天线的相位值确定每个天线组的相位差，再进一步根据相位差确定每个天线组的到达角。具体可 以参见如上介绍的根据本申请的基于蓝牙AOA的定位方法。
S1103，显示设备根据每个天线组的到达角和每个天线组的位置确定控制装置的位置。
在一些实施例中，显示设备包括分别位于显示设备两侧的两个天线组，每个天线组的位置可以根据显示设备的位置和每个天线组相对于显示设备的参考点的位置确定。例如，以显示设备的中心为参考点，其在空间中所处的位置为(a，b，c)，显示设备的宽为d，则两个天线组的位置分别为(a-d/2，b，c)和(a+d/2，b，c)。在一些实施例中，显示设备可以根据到达角和各个天线组的位置确定控制装置的位置。
S1104，显示设备在确定控制装置的位置属于预设范围内时，启动与控制装置建立蓝牙连接的流程。
其中，预设范围位于显示设备的显示方向上，即显示屏的正前方。
显示设备可以与控制装置在进行蓝牙连接之前首先确定控制装置的位置是否在预设的位置范围内，若在，则与控制装置建立蓝牙连接。若不在，则不建立蓝牙连接。由此可以解决空间中包括多个控制装置或者包括多个显示设备时，无法准确建立蓝牙连接的问题。
在一些实施例中，显示设备在根据蓝牙组件接收到的广播信号进行定位控制装置之前，还可以首先检测接收到的广播信号的信号强度。由于显示设备检测到的广播信号的信号强度越大，控制装置与显示设备的距离越短。在一些实施例中，显示设备中可以配置有距离与信号强度的对应关系，若检测到的广播信号的信号强度大于设定阈值，则可以确定发射该广播信号的控制装置与显示设备的距离小于预设距离。预设范围指示的显示设备与控制装置的距离小于或者等于预设距离。例如，预设距离为6米，那么预设范围可以为显示设备的显示方向上的6米范围。基于此，显示设备可以在计算控制装置的位置之前，先判断其与自身的距离，若距离不符合要求就不需要进行计算位置，节约计算资源。
在另外一些情况下，若显示设备接收到广播信号之后，根据广播信号的信号强度确定发送该广播信号的控制装置与显示设备的距离小于预设距离，但是在计算出控制装置的位置之后，确定该位置不属于预设范围(例如在显示设备侧面)，显示设备还可以在显示界面中显示提示信息，用于指示将控制装置移动至预设范围，例如，可以参见图10所示的显示界面。
在一些实施例中，显示设备可以在检测到控制装置的位置属于预设范围之后，停止计算控制装置的位置。已知显示设备在计算控制装置的位置时，是通过天线组接收来自控制装置的蓝牙信号，根据不同的天线接收到的蓝牙信号确定每根天线的相位值，进一步计算每个天线组的相位差，根据相位差确定每个天线组的到达角，然后根据到达角和天线组的位置确定控制装置的位置。可以看出，在计算控制装置的位置的过程中，显示设备需要切换不同的天线进行接收来自控制装置的蓝牙信号，以获取每根天线对应的相位值。所以，在一些情况下，显示设备可以在已经确定控制装置位于预设范围时，停止切换天线的操作，选取天线组中的一根天线进行与控制装置建立蓝牙连接的过程。在一些实施例中，选取的天线可以是预先配置好的，例如可以是天线组中最靠近显示设备外壳的一根天线或者性能最好的一根天线，后续将该天线称为第一天线。显示设备在确定控制装置位于预设范围之后，将只通过第一天线接收蓝牙信号，与控制装置建立蓝牙连接。
在一些实施例中，显示设备与控制装置蓝牙连接的过程可以参见图11所示的流程图，具体包括：
S1301，显示设备通过第一天线向控制装置发送连接请求。
S1302，控制装置接收连接请求，确认显示设备为待连接的设备。
在一些实施例中，显示设备发送的连接请求中可以包括显示设备的标识。
S1303，显示设备通过第一天线向控制装置发送鉴权信息。
例如，鉴权信息可以为Authentication。在一些实施例中，控制装置发送的广播信号中包括用于指示承载数据的数据信道的信息，显示设备在接收到来自控制装置的广播信号时就可以确定与控制装置进行数据交互的数据信道。显示设备可以通过第一天线在数据信道上发送鉴权信息。其中，鉴权信息可以包括询问控制装置支持的蓝牙版本的信息、询问控制装置支持功能的信息或者建立密钥的请求等。在一些实施例中，显示设备可以依次发送上述鉴权信息，例如，显示设备先发送询问控制装置支持的蓝牙版本的信息，然后在接收到控制装置回复的可支持的版本信息之后再继续发送询问控制装置支持功能的信息，依次类推。在一些实施例中，显示设备也可以一次性发送所有的鉴权信息。
S1304，显示设备确定控制装置支持密钥连接。
S1305，向控制装置发送连接密钥。
在一些实施例中，连接密钥可以由显示设备随机生成。
S1306，控制装置接收连接密钥，向显示设备返回连接密钥确认信息。
显示设备在接收到连接密钥确认信息时，就可以通过密钥与控制装置建立蓝牙连接了。在一些实施例中，在建立蓝牙连接之后，显示设备与控制装置每个设定时长后进行一次握手通信，确保双方都处于连接状态。当握手通信失败时，显示设备会断开蓝牙连接并通过蓝牙组件在广播信道上进行扫描，其中，所述在广播信道上进行扫描是用于回连的扫描。当扫描到控制装置发送的广播信号时，可以根据广播信号的指示去对应的数据信道上发送携带密钥的回连请求。其中，回连请求用于当显示设备与已配对的控制装置断开连接时，用于重新建立连接而发送给控制装置的连接请求，其携带有显示设备的设备标识和用于校验的验证密钥。控制装置接收到回连请求时，可以根据密钥重新与显示设备建立连接。
本申请提出的蓝牙连接的方法可以应用于多种场景中，例如显示设备与控制装置进行配对的场景或者解配场景等。下面，结合具体场景对本申请提出的方案进行介绍。
场景一：配对场景。
在一些实施例中，以配对场景中包括两个显示设备(后续分别简称为第一显示设备和第二显示设备)和一个控制装置为例进行介绍。在该场景中，控制装置可以是位于左侧的显示设备(以左侧的显示设备为第一显示设备为例)的正前方的。第一显示设备可以通过第一显示设备包括的至少两个天线组在广播信道上扫描蓝牙信号。第二显示设备也可以通过第二显示设备包括的至少两个天线组在广播信道上扫描蓝牙信号。若第一显示设备和第二显示设备均扫描到来自控制装置的广播信号，则第一显示设备和第二显示设备均可以根据广播信号计算控制装置的位置。其中，广播信号中包括用于检测广播信号的相位值的CTE。下面以第一显示设备为例介绍计算控制装置位置的过程。第一显示设备可以首先根据广播信号中的CTE确定每根天线对应的相位值，然后根据每根天线的相位值计算每个天线组的相位差，进而可以根据每个天线组的相位差计算每个天线组的到达角。显示设备确定控制装置的位置的详细过程可以参见前面结合公式(1)-(3)对基于蓝牙AOA的定位方法的详细说明，在此不再赘述。
在一些实施例中，第一显示设备和第二显示设备中可以分别配置有一个可连接的位置范围，该可连接的位置范围可以为第一(或第二)显示设备的显示方向上的位置范围。为了便于描述，后续称为预设范围。第一显示设备在确定控制装置的位置之后，可以进一步确定该位置是否位于第一显示设备的预设范围内。同理，第二显示设备也可以确定控制装置的位置是否位于第二显示设备的预设范围内。若控制装置的位置属于第一显示设备的预设范围，而不位于第二显示设备的预设范围内，则第一显示设备启动与控制装置进行蓝牙连接的过程，第二显示设备不会启动建立蓝牙连接的流程。具体建立蓝牙连接的过程可以参见上述图11，在此不再详述。
相关技术中，显示设备在检测到来自控制装置的蓝牙信号之后，就会在广播信道上向控制装置发送连接请求。例如，在场景一中，第一显示设备和第二显示设备都会在广播信道上发送连接请求，这样可能会导致两个设备方法的连接请求互相干扰，造成两条连接请求都发送失败的情况。本申请提出的方案中，当第一显示设备和第二显示设备都检测到控制装置发送的蓝牙信号时，两个设备不会直接发送连接请求，而是先计算控制装置的位置，并确定控制装置的位置是否在自身的预设范围内，若不在的话，将不会向控制装置发送连接请求，避免影响其他的显示设备与控制装置建立蓝牙连接。
下面，结合显示设备和控制装置中包括的蓝牙组件对场景一下的具体实现方式进行介绍，为了便于表述，后续将显示设备中包括的蓝牙组件中的蓝牙控制器称为第一蓝牙控制器CTR_A，将显示设备中包括的处理器称为第一处理器PROC_A，将控制装置中包括的蓝牙控制器和处理器分别称为第二蓝牙控制器CTR_B和第二处理器PROC_B。参见图12，为本申请一些实施例的场景一下的一个具体的实现流程，具体包括：
S1401，第一蓝牙控制器CTR_A通过天线扫描广播信道，接收到来自控制装置的广播信号。
S1402，第一蓝牙控制器CTR_A将接收到的广播信号发送到第一处理器PROC_A。
S1403，第一处理器PROC_A根据广播信号确定控制装置的位置，并确定控制装置的位置属于预设范围。
S1404，第一处理器PROC_A向第一蓝牙控制器CTR_A发送连接指令。
其中，连接指令用于指示控制装置满足建立蓝牙连接的要求，可以与其建立蓝牙连接。
S1405，第一蓝牙控制器CTR_A接收连接指令，向第二蓝牙控制器CTR_B发送连接请求。
在一些实施例中，第一蓝牙控制器CTR_A可以在广播信道中发送连接请求。连接请求中可以包括显示设备的标识。
S1406，第二蓝牙控制器CTR_B接收连接请求，向第二处理器PROC_B转发连接请求。
第二处理器PROC_B可以将连接请求中的显示设备的标识进行存储。
S1407，第一蓝牙控制器CTR_A向第一处理器PROC_A发送连接指令确认信息。
其中，连接指令确认信息用于指示已经发送连接请求。在一些实施例中，第一处理器PROC_A在接收到连接指令确认信息之后，可以在显示设备的显示屏中显示用于指示正在建立蓝牙连接的信息。
上述步骤S1406和步骤S1407可以不分先后顺序。
S1408，第一蓝牙控制器CTR_A向第二蓝牙控制器CTR_B发送鉴权信息和连接密钥。
S1409，第二蓝牙控制器CTR_B向第一蓝牙控制器CTR_A发送鉴权信息的回复信息和连接密钥确认信息。
由此，显示设备与控制装置可以通过连接密钥建立蓝牙连接。显示设备和控制装置中都可以保存对方的标识和连接密钥。
上述举例均以场景中包括多个显示设备和一个控制装置为例进行介绍的。本申请提出的方法还可以用于一个现实设备与多个控制装置的场景。当存在多个控制装置和一个显示设备时，显示设备还可以计算各个控制装置的位置，并判断各个控制装置的位置是否位于自身的预设范围，然后与位于自身预设范围内的控制装置建立连接。例如，在该场景中，显示设备可以与位于中间的控制装置建立连接。
场景二：解配场景。
在一些实施例中，当显示设备与控制装置建立蓝牙连接之后，当控制装置与显示设备断开连接时，例如，控制装置可以响应于用户按动某一个按键(比如菜单键)的操作确定需要与显示设备断开连接，删除存储的显示设备的标识和连接密钥，此时显示设备再启动回连流程时，向控制装置发送带有连接密钥的回连请求，由于控制装置中已经删除连接密钥，所以控制装置接收到回连请求后也无法根据连接密钥与显示设备重新建立连接，回连失败，显示设备会将存储的控制装置的标识和连接密钥删除，解除配对。但是，相关技术中，当场景二中存在多个显示设备时，可能会出现解配失败的问题。例如，以场景二中包含第一显示设备和第二显示设备为例，第一显示设备为与控制装置配对的显示设备。控制装置与第一显示设备断开连接，删除第一显示设备的标识和连接密钥，并向外发送广播信号。此时，若第二显示设备先接收到广播信号，第二显示设备就会与控制装置建立连接，导致第一显示设备无法与控制装置进行验证连接密钥，也就导致第一显示设备无法解配成功。本申请提出的建立蓝牙连接的方法中，第二显示设备在接收到广播信号后，会先进行确定控制装置的位置是否在第二显示设备的预设范围内，若不在，则会禁止启动与控制装置及建立连接的流程，那么就不会影响第一显示设备的解配过程。
场景三：一触即连场景。
相关技术中，实现显示设备与控制装置一触即连采用的方法是通过在显示设备上添加近距离无线通信(Near Field Communication，NFC)模块，控制装置靠近显示设备中NFC模块的位置，与显示设备连接。但是这种方法成本较高。
本申请一些实施例提供了一种一触即连的方法，通过蓝牙定位技术，确定控制装置的位置，在确定控制装置与显示设备的设定区域重叠时，建立控制装置与显示设备的连接。
在一些实施例中，显示设备可以在检测到来自控制装置的蓝牙信号时，进行计算控制装置的位置。显示设备在确定控制装置的位置之后，可以进一步确定控制装置与显示设备的设定区域是否重叠。例如，可以参见图13所示的场景图，显示设备的设定区域为显示设备左上角的区域A，区域A的长为a，宽为b。设显示设备的参考点的位置为(0，0，0)，显示设备的长为2c，宽为2d，则显示设备设定区域内包括的位置范围为：0>x>a-c，0<y<d-b，z＝0。当控制装置的位置满足该范围时，即可以与显示设备建立连接。
在一些实施例中，如果显示设备确定控制装置的位置的z＝0，但是控制装置的x坐标和y坐标不满足上述的范围的情况下，显示设备还可以在显示界面中显示如图14所示的显示界面，以提示用户移动控制装置至显示设备的设定区域。
(2)与针对显示设备的画中画窗口调节关联的实施方式
画中画(PiP，Picture-in-Picture)是一种呈现方式，通过一大一小两个画面叠加写的方式，呈现两个窗口显示，主要以视频显示为主，视频来源可以是不同的电视频道、视频播放源、摄像头、游戏设备等。但随着对显示设备的应用，也不局限于视频显示，还可以是网页显示等。相关技术关于画中画视图显示区的控制或调整主要是用户通过控制装置(如遥控器)控制操作菜单实现画中画显示区域的显示控制，例如，用户通过遥控器在第一级菜单中选择窗口设置，在第二级菜单(第一级菜单的子菜单)选择窗口大小或者窗口位置，在第三级菜单(第二级菜单的子菜单)选择列出的具体窗口大小或者具体窗口位置。然而，上述控制或调整画中画视图显示区的操作过程繁琐，只能根据已有列出的选项设置画中画视图显示区，用户体验感差。
本申请一些实施例提供一种显示设备，所述显示设备包括显示屏、蓝牙控制器和处理器；所述处理器与所述显示屏和所述蓝牙控制器连接；所述蓝牙控制器，被配置为通过多个蓝牙天线与控制装置蓝牙通信，所述蓝牙控制器基于蓝牙5.1，支持蓝牙AOA定位技术，AOA法通过信号的角度信息进行定位估算，控制装置(发射端)利用单一天线发射寻向讯号，显示设备(接收端)内置天线阵列，当信号通过时，因阵列中接收到距离不同而产生相位差异，提高定位的精确度。
多个蓝牙天线构成天线阵列，接收控制装置发射的控制指令或请求，蓝牙控制器与多个蓝牙天线之间设置开关，所述开关用于控制蓝牙天线选择或切换。蓝牙天线一般是贴片天线，在不影响显示设备外观的前提下，保证功能的正常；也可以是其他的隐藏式天线。
在显示设备开启画中画功能时，处理器启动基于蓝牙AOA定位交互功能，且与同样具备蓝牙AOA定位技术的控制装置进行交互。在显示设备关闭画中画功能时，处理器将基于蓝牙AOA定位交互功能关闭。
如图15所示，显示屏显示用户界面，所述用户界面包括第一视图显示区2601和第二视图显示区2602，所述第一视图显示区是全屏显示，所述第二视图显示区以画中画显示在所述第一视图显示区上。
控制装置可以是遥控器，显示设备与遥控器之间通过各自的蓝牙控制器实现无线连接。在一些实施例中，可以是基于蓝牙协议的无线通信，且支持蓝牙AOA定位技术。
处理器检测到控制装置的位置在第二视图显示区内，用户可通过控制装置选择第二视图显示区的菜单，控制选择窗口大小请求，即处理器通过蓝牙控制器接收的第一控制请求，例如图15中菜单2603，通过菜单选择对于第二视图显示区的窗口大小的设定。
在一些实施例中，菜单2603是在OSD(On ScreenDisplay)层展示，菜单可以是透明OSD显示，可以是透明颜色OSD显示，也可以是颜色OSD显示。
处理器通过所述蓝牙控制器接收用户输入的第一控制请求，确定所述控制装置在所述第二视图 显示区的实时位置坐标，以及，起始位置坐标。所述第一控制请求是用户通过控制装置输入的关于所述第二视图显示区调整显示大小的请求。显示设备通过蓝牙天线、蓝牙控制器接收无线电波数据包，从无线电波数据包提出请求数据解析为第一控制请求，同时从无线电波数据包获取对应的位置信息，建立显示设备中控制装置的位置坐标与控制装置之间的对应关系。
在一些实施例中，获取显示设备端的天线阵列，以及对应蓝牙天线的位置，对接收的无线电波数据包分析，确定显示设备的蓝牙天线与控制装置的蓝牙天线之间的角度和位置。对于选择的蓝牙天线，基于蓝牙AOA定位技术，建立显示设备的中坐标信息与控制装置的位置之间的对应关系。
处理器通过所述蓝牙控制器接收用户输入的移动请求，通过对移动请求的移动趋势方向的判断确定有效起始坐标，以及，通过对移动请求变化的判断确定有效终止坐标，所述移动请求包含所述控制装置的位置信息。
有效起始坐标的确定，处理器获取第一预设时间内的移动请求，确定所述控制装置的第一移动趋势方向；获取第二预设时间内的移动请求，确定所述控制装置的第二移动趋势方向，所述第二预设时间在所述第一预设时间之后；当所述第一移动趋势方向和所述第二移动趋势方向相同时，对应的起始位置坐标为有效起始坐标。
例如，先获取Nms时间内控制装置的移动请求，通过对其移动请求的计算，确认第一移动趋势方向为N1，再获取Mms时间内控制装置的移动请求，通过对其移动请求的计算，确认第二移动趋势方向为N2。比较N1和N2的方向，若相同，则对应的起始位置坐标为有效起始坐标，否则，有效起始坐标的确认无效。需要重复上述的过程再次确定有效初始坐标。
在一些实施例中，第一移动趋势方向和第二移动趋势方向可以是一个方向的范围，比如可以将360°划分为8个方向，每个方向的区间范围为45°。例如，以向右水平为0°，右上方为22.5°到67.5°，上方为67.5°到112.5°。
在一些实施例中，移动趋势方向，可以根据移动请求的坐标信息，确定一段时间内的起止位置的斜率，从而确定移动趋势方向。坐标信息可以是第一视图显示区的坐标系，也可以是第二视图显示区的坐标系。
如图16所示，有效终止坐标的确定是当所述移动请求超出所述第二视图显示区的边界，确定对应边界的坐标为有效终止坐标。且超出第二视图显示区边界的轨迹将不显示。
如图17所示，有效终止坐标的确定，获取所述移动轨迹的第一移动方向J；当所述移动轨迹呈现出与第一移动方向J相反的第二移动方向K时，确定所述移动轨迹的第一移动方向J对应的终点坐标为有效终止坐标。
根据所述有效起始坐标和所述有效终止坐标，确定所述移动请求的移动轨迹，例如，以第二视图显示区的坐标系确定的有效起始坐标和有效终止坐标；以有效起始坐标为原点坐标重新定义的相对坐标系，通过计算相对于原点坐标的相对有效终点坐标的斜率和相对纵坐标Y，确定移动轨迹。
如图18A-图18H所示，在所述第二视图显示区中呈现所述移动轨迹，以及根据所述移动轨迹的方向调整所述第二视图显示区的显示大小。例如，图18A示出当确定移动轨迹为箭头所指右上方时第二视图显示区2602会向右和向上分别拉伸，且第二视图显示区2602窗口大小变为2602a。类似地，图18B-图18H分别示出了当确定移动轨迹为箭头所指的相应方向时第二视图显示区2602会向相应方向拉伸，其中第二视图显示区2602窗口大小分别变为2602b-2602h。
第二视图显示区窗口大小的变化可以取决于移动轨迹的长短；在一些实施例中窗口大小的变化可以取决由移动请求的速度，也可以是移动轨迹长短和移动请求速度共同决定。
在一些实施例中移动请求并非如图18A-图18H所示的绝对直线，移动请求可能是存在弧度，移动轨迹根据有效起始坐标和有效终止坐标确定的，移动轨迹可以如图18A-图18H所示带箭头的线条，也可以是不带箭头的线条，也可以是粗细不等的线条等其他呈现轨迹的方式；移动轨迹也可以隐藏。
在一些实施例中，移动轨迹也可以根据有效起始坐标、有效终止坐标以及移动请求来确定，可能呈现的轨迹是存在弧度，模拟用户实际对控制装置的操作手势。
本申请提供一种显示设备，包括显示屏、蓝牙组件和处理器；所述处理器与所述显示屏和所述蓝牙组件连接，所述蓝牙组件与控制装置(例如遥控器)进行无线连接。所述显示屏被配置为显示第一视图显示区和第二视图显示区，所述第一视图显示区是全屏显示，所述第二视图显示区以画中画显示在所述第一视图显示区上。所述处理器被配置为：响应于所述蓝牙组件接收用户输入的第一控制请求，确定所述控制装置在所述第二视图显示区的实时位置坐标，以及，起始位置坐标，其中，所述第一控制请求是用户通过控制装置输入的关于所述第二视图显示区调整显示大小的请求；响应于所述蓝牙组件接收用户输入的移动请求，确定有效起始坐标，以及有效终止坐标；根据所述有效起始坐标和所述有效终止坐标，确定所述移动请求的移动轨迹，以及，在所述第二视图显示区中呈现所述移动轨迹；根据所述移动轨迹的方向调整所述第二视图显示区的显示大小。实现交互控制第二视图显示区的显示大小，操作简单，提升用户的体验感。
本申请一些实施例提供还一种显示设备，处理器检测到控制装置的位置在第二视图显示区内，用户可通过控制装置选择第二视图显示区的菜单，控制选择窗口位置请求，即处理器通过蓝牙组件接收的第二控制请求，例如图15中菜单2603，通过菜单选择对于第二视图显示区的窗口位置的设定。

如图19中2602n和2602p对应的情况，当所述第二视图显示区的部分区域移出所述第一视图显示区边界时，所述第二视图显示区对应的区域不显示。

(3)与通过遥控装置的移动来控制显示设备关联的实施方式
相关技术中，对显示设备的遥控方法是通过用户按动遥控器上的按键以及预先定义好的各个按键的指示命令来实现遥控显示设备，这种遥控方法能够实现的控制指令比较少，只能进行简单的调台或者调节音量等。如果想要实现对于显示设备的触控操作，需要给显示设备配置触摸屏和触控系统，使得显示设备的成本较高。
本申请一些实施例提供了一种显示设备及控制显示设备的方法，显示设备通过检测控制装置在显示设备所处的空间包括的长方体空间中的位置变化轨迹确定需要执行的指令，即本申请在不需要配置触控系统和触摸屏的基础上提出了一种类似于触控操作的方法，通过控制装置实现更多的控制指令。
根据本申请一些实施例提出的控制显示设备的方法可以由显示设备来执行。一种控制显示设备的方法，具体包括如下步骤：
显示设备接收来自控制装置的蓝牙信号。
在一些实施例中，显示设备中包括用于接收蓝牙信号的天线组，显示设备可以通过天线组持续接收来自控制装置的蓝牙信号。其中，显示设备可以包括的天线组的数量可以大于或者等于2。
显示设备根据蓝牙信号对控制装置进行定位，并获取控制装置在配置的长方体空间内的移动轨迹。
其中，长方体空间是显示设备所处的空间中的一个长方体形状的空间。长方体空间是预先基于用户配置的一个平面通过设定规则形成的，后续将该平面称为第一面，第一面是长方体空间的外表面中的一个面。第一面在配置的空间坐标系中的位置与显示屏包括的各个像素在空间坐标系中的位置存在映射关系，第一面的尺寸与显示屏的尺寸存在比例关系。在一些实施例中，在建立第一面与显示屏的对应关系时，可以将第一面切分成M个小方格，M个小方格中每个小方格的边长可以为蓝牙的定位精度，每个小方格都对应到显示屏中的对应区域上。在一些实施例中，空间坐标系是在显示设备中预先配置的，用于指示显示设备所处的空间，空间坐标系的原点为显示设备的参考点，例如显示设备的参考点可以是显示设备的中心点或者显示设备中天线组的位置。
在一些实施例中，显示设备接收到的来自控制装置的蓝牙信号中可以包括用于定位的固定频率拓展信号CTE，显示设备可以通过检测蓝牙信号中包括的CTE对控制装置进行定位，获取控制装置在空间坐标系中的位置坐标，后续为了便于描述，将控制装置在空间坐标系中的位置坐标简称为控制装置的位置。
显示设备在确定控制装置的位置之后，可以进一步判定控制装置的位置是否位于长方体空间中。一种可能的实现方式中，显示设备中可以配置有长方体空间的坐标范围，比如：a<x<b，c<y<d，e<z<f，显示设备在确定控制装置的位置之后，判断其位置是否满足上述范围。若满足，则可以确定控制装置位于长方体空间中。显示设备在确定控制装置位于长方体空间中之后，可以记录控制装置在长方体空间中的移动轨迹，即记录控制装置的位置随着时间的变化情况，形成控制装置的移动轨迹。为了便于描述，可以将控制装置在长方体空间中的移动轨迹称为第一移动轨迹。
显示设备根据第一移动轨迹和显示屏当前的显示界面，确定待执行的控制指令。
在一些实施例中，显示设备可以根据第一面在空间坐标系中的位置与显示屏包括的各个像素在空间坐标系中的位置存在的映射关系，确定第一移动轨迹投影到显示屏中的第二移动轨迹。为了能够更清晰的理解根据映射关系从长方体空间中的移动轨迹投影到显示屏的过程，以一个具体的举例进行说明。
例如，控制装置在长方体空间中形成的第一移动轨迹的某一点(例如，称为第一点)的坐标为(10，20，30)，第一面的坐标范围为：9<x<15，19<y<23，z＝10，则该第一点投影到第一面上得到的点(例如，称为第二点)的坐标为(10，20，10)。第一面与显示屏的映射关系可以为x1＝x-9，y1＝y-10，z1＝z-10，其中，x、y、z表示第一面上的坐标，x1、y1、z1表示显示屏上各个像素的坐标。那么第一面上的第二点(10，20，10)进一步根据映射关系从第一面投影到显示屏上得到的点(例如，称为第三点)的坐标为(1，10，0)。由此，显示设备可以根据上述映射方法，将第一移动轨迹映射到显示屏中获取第二移动轨迹。
在一些实施例中，显示设备中还可以被配置有显示屏上的移动轨迹与控制指令的对应关系。例如，当显示屏中在播放视频时，移动轨迹为向右侧划过1厘米，对应的控制指令为将播放的视频快进10秒。显示设备在确定第二移动轨迹之后，可以根据预先配置的移动轨迹与控制指令的对应关系确定第二移动轨迹对应的控制指令，然后执行该控制指令。
由于在相关技术中，想要实现对于显示设备的触屏操作需要给显示设备配置触控系统和触摸屏，成本较高。而本申请提出了一种类似触控的控制方法，获取控制装置在显示设备所处空间中包括的一个长方体空间中移动轨迹，根据预先配置的映射关系将该移动轨迹映射到显示设备的显示屏上，并根据映射后的轨迹与控制指令的映射关系确定需要执行的控制指令，从而实现对显示设备的控制。
在一些场景下，显示设备在根据控制装置在长方体空间中的移动轨迹确定待执行的控制指令之前，可以首先确定长方体空间的位置以及包括的范围。在一些实施例中，长方体空间可以是用户通过控制装置预先配置在显示设备中的，例如，在一种可选的方法中，用户可以针对不同的应用程序配置不同的长方体空间，显示设备还可以将应用程序与对应的长方体空间关联存储。当用户打开某一个的应用程序时，就可以通过控制装置在该应用程序对应的长方体空间中进行操作，以实现控制 显示设备。在一些实施例中，长方体空间还可以是用户在每一次使用之前进行配置的。下面，针对上面两种实施方式进行具体介绍。
在一些实施例中，长方体空间是在用户每一次使用之前进行配置的，下面对具体的配置过程进行介绍。在一些实施例中，显示设备可以提供如图20A所示的显示界面，图20A所示的显示界面中包括在显示设备所处的空间中以显示设备的参考点为原点建立的空间坐标系，例如，显示设备的参考点即为显示设备的中心点，如图20A中的A点。在一些实施例中，显示设备还可以根据用户预先输入的显示设备所处空间的平面图(或者也可以直接输入空间的三维立体图)，对显示设备所处的空间进行三维建模，然后在建好的模型中构建以显示设备的参考点为原点的空间坐标系，例如，可以参见如图20B所示的显示界面。
在一些实施例中，显示设备可以通过天线组接收来自控制装置的蓝牙信号，根据蓝牙信号计算控制装置的位置。控制装置的位置即为控制装置在空间坐标系下的坐标。显示设备在确定控制装置的位置之后，可以根据接收到的来自控制装置的选择命令来确定长方体空间的第一面，然后基于第一面通过预先设定的规则形成长方体空间，所述选择命令用于指示用户在空间坐标系中选择的至少三个点。下面，对确定长方体空间的第一面以及根据第一面进一步确定长方体空间进行具体介绍。
在一些实施例中，控制装置可以响应于用户操作，比如可以是用户按动某一个按键的操作，将选择命令携带在蓝牙信号中发送给显示设备，显示设备可以根据接收到的选择命令在空间坐标系下确定长方体空间的第一面。在一些实施例中，显示设备可以接收来自控制装置的至少三个选择命令，每一个选择命令都对应于确认一个用于构建长方体空间的参考点，在确认至少三个参考点之后，根据至少三个参考点确定第一面。在一些实施例中，在根据至少三个选择命令确定至少三个参考点的过程中，可以将最先确认的两个参考点之间的连接线作为第一面的一条边。第一面的尺寸与显示屏的尺寸存在比例关系，比如，第一面的长与显示屏的长的比值和第一面的宽与显示屏的宽的比值可以是相同的。
下面，以一个具体的举例介绍显示设备根据选择命令确定参考点的过程进行介绍。例如，根据至少三个选择命令中的第一选择命令确定第一参考点。显示设备在接收到来自控制装置的第一选择命令时，根据此时获取到的控制装置的位置在显示屏所显示的空间坐标系中被显示为第一参考点，例如第一参考点可以为一个黑色的圆点，可以参见图20C所示的示意图，其中的B点即为第一参考点，第一参考点在显示屏中显示的空间坐标系下的坐标即为控制装置在实际的空间坐标系中的坐标。在一些实施例中，显示设备可以采用上述方法确定第二参考点、第三参考点和第四参考点等。三个参考点即可以确定一个平面(即第一面)，当然也可以采用更多的参考点来确定第一面，本申请对于用于确定第一面的参考点的数量不作具体限定。
如下以显示设备通过三个参考点确定第一面为例进行介绍，将这三个参考点分别称为第一参考点、第二参考点和第三参考点，将对应于这三个参考点的选择命令分别称为第一选择命令、第二选择命令和第三选择命令。显示设备在确定第一参考点(即B点)之后，可以根据用户移动控制装置的操作，将控制装置的位置变化轨迹显示在显示界面中，例如可以参见图20D所示的示意图，其中的虚线即为确认B点之后的控制装置的移动轨迹。在一些实施例中，若显示界面中显示如图20D所示的示意图时，还可以进行显示确认B点之后的控制装置的移动轨迹的长度。当然，显示设备也可以不显示确认B点之后的控制装置的移动轨迹。在一些实施例中，显示设备可以在确认B点之后，根据接收到的第二选择命令来确定第二参考点并在显示屏中进行显示，例如可以显示如图20E所示的示意图，图20E所示的示意图中的C点即为第二参考点。在一些实施例中，显示设备可以在确定第二参考点之后，根据接收到的第三选择命令确定第三参考点。在一些实施例中，第三参考点可以在以BC连接线为轴的圆柱体内部或者侧面上任一点。例如可以参见图20F所示的示意图，第三参考点可以取图20F所示的圆柱体的侧面上或者圆柱体内部的任意一点。第三参考点不位于BC连接线上，图20F示出的圆柱体的底面圆半径与BC连接线的比值与显示设备的长宽比相等，或者底面圆半径与BC连接线的比值与显示设备的宽长比相等。显示设备在根据第三选择命令确定第三参考点之后，可以在显示屏中显示的空间坐标系中进行显示，例如可以显示如图20G所示的示意图，图20G所示的D点即为第三参考点。示例性地，确定的第三参考点(即D点)在图20F所示的圆柱体中的位置可以参见图20H所示的示意图，点D位于圆柱体的侧面的D 1D 2连接线上。由此，即可以确定长方形D 1D 2BC即为第一面。在一些实施例中，显示设备还可以在显示屏中显示确定好的第一面，例如，可以显示如图20I所示的示意图。
在一些实施例中，显示设备在确定第一面之后，可以基于第一面通过预先设定的规则生成长方体空间。例如，预先设定的规则可以是选取与第一面垂直的两个方向中的任意一个方向，在此方向上创建与第一面大小相同且与第一面平行的第二面，第二面与第一面之间的距离可以是预先设定好的，例如第一面和第二面之间可以间隔N倍的蓝牙的定位精度，其中，N可以大于或者等于2。示例性地，长方体空间的示意图可以参见图20J，图20J中长方形D 1D 2BC即为第一面，选取的垂直于第一面的方向即为R方向，基于R方向创建的长方形D 1'D 2'B'C'为第二面。其中，BB'连接线垂直于第一面和第二面。
显示设备在完成配置长方体空间之后，可以将长方体空间的范围进行存储，然后就可以根据检测到的控制装置的位置是否数据长方体空间的范围来判断控制装置是否位于长方体空间了。显示设备在确定控制装置位于长方体空间之后，就可以获取控制装置的移动轨迹，并根据移动轨迹确定需要执行的控制指令。
以上，介绍了显示设备在每一次使用之前配置长方体空间的过程。
在一些实施例中，长方体空间可以是预先配置在显示设备中的。例如，可以针对每个应用程序配置一个长方体空间。比如，在家用场景下，为视频类的应用程序创建长方体空间时，为了便于用户观看视频，可以将长方体空间的位置建立在用户坐在沙发上可以方便操作的位置。在一些实施例中，配置长方体空间的过程可以参见上述实施例中的介绍。在基于不同的应用程序预先配置长方体空间的情况下，显示设备在确定用户通过控制装置配置长方体空间之后，可以将长方体空间与对应的应用程序进行关联存储。以保证用户在下一次使用该应用程序时就可以去对应的位置通过控制装置进行相应操作以控制显示设备，不需要在每一次使用之前配置长方体空间，节约了用户的时间。
显示设备在响应用户打开某一个应用程序的操作，确定该应用程序对应的长方体空间的位置以及包括的范围，然后可以检测控制装置的位置是否位于该范围内，若在，即可以继续获取控制装置的位置随时间的变化情况(即控制装置在长方体空间内的移动轨迹)来执行对应的控制指令。
显示设备获取控制装置的位置的详细过程可以参见前面结合公式(1)-(3)对基于蓝牙的定位方法的详细说明，在此不再赘述。
示例性地，对显示设备如何根据控制装置的位置的变化获取控制装置的移动轨迹的过程进行简单的如下介绍。
在一些场景下，显示设备在计算控制装置的位置之后，还可以采用计算质心坐标的方式删除一些误差较大的位置点，然后通过删除误差大的位置点之后剩余的位置点组成控制装置的移动轨迹。在一些实施例中，显示设备可以获取预先设定的一段时间内的控制装置的多个位置点，可以计算所述多个位置点的质心坐标，然后删除所述多个位置点中距离质心坐标较远的位置点。例如，显示设备可以间隔第一设定时长计算一次控制装置的位置，比如间隔1秒钟，显示设备可以获取第二设定时长(大于第一设定时长，可以是多个第一设定时长的总时长)内，比如10秒，计算的控制装置的10个位置点，分别为：(x 3，y 3)、(x 4，y 4)、(x 5，y 5)……(x 13，y 13)。显示设备可以计算这10个位置点的质心坐标，例如，可以采用如下公式(4)-公式(5)计算上述10个位置点的质心坐标：
Figure PCTCN2022095742-appb-000005
Figure PCTCN2022095742-appb-000006
其中，(x c，y c)为上述10个位置点的质心坐标，m为上述10个位置点的质量和，M y为上述10个位置点分别相对于y轴的静力矩之和，M x为上述10个位置点分别相对于x轴的静力矩之和。
在一些实施例中，上述10个位置点分别相对于y轴的静力矩之和可以采用如下公式(6)计算得出：
Figure PCTCN2022095742-appb-000007
其中，M y为上述10个位置点分别相对于y轴的静力矩之和，m i为上述10个位置点中任一位置点的质量，x i上述10个位置点中任一位置点的横坐标。
在一些实施例中，上述10个位置点分别相对于x轴的静力矩之和可以采用如下公式(7)计算得出：
Figure PCTCN2022095742-appb-000008
其中，M x为上述10个位置点分别相对于x轴的静力矩之和，m i为上述10个位置点中任一位置点的质量，y i上述10个位置点中任一位置点的纵坐标。
显示设备在计算出上述10个位置点的质心坐标之后，可以分别计算该10个位置点与质心坐标的距离，将距离质心坐标最远的几个位置点删除，本申请对于删除位置点的数量不作具体限定。显示设备在删除之后，可以根据剩余的位置点获取控制装置的移动轨迹。或者，显示设备还可以对剩余的位置点取平均值，然后将平均后的结果作为在这10秒内控制装置的位置。
在在一些实施例中，显示设备在根据控制装置的多个位置点确定控制装置的运动轨迹时，还可以采用最小二乘法对控制装置的运动轨迹进行平滑化处理。即，显示设备可以根据计算得到的多个控制装置的位置点确定一条拟合度最好的曲线(拟合度指的是曲线与实际计算得到的多个位置点的吻合程度)，并可以以这条曲线作为控制装置的运动轨迹。例如，显示设备可以采用人工预先配置的一条曲线(或者一条直线)去逼近计算得到的多个位置点，使得预先配置的曲线上的点与各个位置点的残差的加权平方和达到最小，从而使得该曲线相对于多个位置点的拟合度最好。将该曲线作为控制装置的运动轨迹。采用这种方法获取的运动轨迹更加平滑且更加贴近控制装置在空间中实际的运动轨迹。
由于蓝牙信号在传输过程中可能会存在信号噪声、时钟抖动和信号传播延迟等问题，尤其是在室内的环境中，还可能会出现信号遮挡以及信号反射等问题。这些问题都会导致显示设备计算得到的控制装置的位置存在误差，那么同时就会导致显示设备获取的控制装置的移动轨迹有偏差。通过计算一定时长内多个位置点的质心坐标，删除距离质心坐标较远的位置点，可以提升显示设备获取的控制装置的轨迹的准确性。并且显示设备在确定运动轨迹时，还可以采用最小二乘法对运动轨迹进行平滑化处理，确定一条与实际计算的位置点拟合度最高的曲线作为控制装置的运动轨迹。
在一些实施例中，显示设备在配置长方体空间之后，还可以进一步配置一个识别空间，该识别空间可以与长方体空间共用一个面，识别空间的大小和形状可以与长方体空间相同，也可以不相同，本申请对于识别空间的大小和形状不作具体限定。在一些实施例中，长方体空间和识别空间所共用 的那个面可以是与显示屏存在映射关系的第一面，也可以是长方体空间中与第一面平行的那个面。为了便于描述，将长方体空间与识别空间共用的面简称为第二面，第二面的中心点到显示屏所在平面的距离小于识别空间其他的面到显示屏所在平面的距离。也就是说，相比与长方体空间，识别空间可以距离显示设备更远，距离用户更近，以方便用户操作。例如，在图20J示出的长方体空间的基础上，识别空间的示意图可以参见图21A。在图21A中长方体L 1即为长方体空间的示意图，长方体L 2即为识别空间的示意图。长方体L 1和L 2共用的面为长方形D 1D 2BC。当然，长方体L 1和L 2也可以共用与长方形D 1D 2BC平行的面，即长方形D 1'D 2'B'C'，在图21A中，以长方体L 1和L 2共用长方形D 1D 2BC为例进行展示。
在一些实施例中，显示设备在进行确定控制装置的位置是否位于长方体空间之前，还可以先确定控制装置的位置位于识别空间。也可以理解为，显示设备确定控制装置是否经过识别空间到达长方体空间。在一些实施例中，若显示设备确定控制装置并不是经过识别空间到达长方体空间，而是通过其他的路径到达长方体空间时，显示设备将不会根据控制装置的移动轨迹执行相应的控制指令。由此避免用户误操作的问题。
在一些实施例中，显示设备在检测到控制装置的位置位于识别空间之后，还可以确定控制装置在识别空间的位置投射到第一面上形成的点的坐标，为了便于描述，将该投射到第一面上的点称为第一点。在一些实施例中，显示设备可以根据第一面和显示屏的映射关系确定第一点投影到显示屏上的投影位置，为了便于描述，后续将该投影位置简称为第二点，还可以在显示屏中显示第二点，例如可以通过黑色圆点或者箭头的形式显示第二点。例如，可以参见图21B，图21B展示了在播放视频的过程中，显示设备确定控制装置的位置位于识别空间时，在当前的显示界面中以箭头的形式显示第二点。
显示设备可以在确定控制装置位于识别空间之后，再确定控制装置是否到达长方体空间，若到达，即根据控制装置在长方体空间中的移动轨迹执行相应的控制指令。
本申请提出的控制显示设备的方法可以应用于视频播放、音频播放或者绘图等多个场景中，下面，以视频播放的场景为例对本申请提出的方案进行具体介绍。
在一些实施例中，显示设备在播放视频时，可以获取存储的视频播放场景对应的长方体空间和识别空间的位置和包括的范围等信息。存储的长方体空间的信息可以是在播放视频之前配置的，也可以是用于预先配置好并存储在显示设备中的。显示设备在播放视频的过程中可以持续获取来自控制装置的蓝牙信号，并根据持续接收到的蓝牙信号确定控制装置的位置，即控制装置位于空间坐标系下的坐标。进而显示设备可以判断确定的控制装置的位置是否处于识别空间包括的范围内，若不处于，则继续播放视频。若处于，则显示设备可以获取控制装置的位置投影到与显示屏存在映射关系的第一面上的第一点，根据所述映射关系确定第一点投影到显示屏上的第二点，并可以在显示屏中以预先设定的标识显示第二点。例如，显示设备在播放视频时可以提供如图22所示的显示界面，在进行显示第二点时可以参见如图21B所示的显示界面。在图21B所示的显示界面中，示例性的采用箭头的形式来显示第二点，当然也可以采用其他的形式，例如以黑色的圆点的形式来显示第二点，本申请对此不作具体限定。
在一些实施例中，显示设备在显示第二点之后可以继续判断控制装置的位置是否位于长方体空间，即判断控制装置是否由识别空间到达长方体空间。若显示设备确定控制装置由识别空间到达长方体空间，则可以获取控制装置在长方体空间的移动轨迹，还可以获取控制装置在长方体空间内的移动轨迹投影到第一面上的第一移动轨迹。然后根据第一面和显示屏的映射关系确定第一移动轨迹投影到显示屏上的第二移动轨迹。进而显示设备可以根据预先配置的移动轨迹与控制指令的对应关系确定需要执行的控制指令。
例如，在视频播放场景中，预先配置的移动轨迹与控制指令的对应关系中包括：当移动轨迹为向右滑动的一条直线时，对应的控制指令为视频快进T秒，其中，T与直线的长度存在对应关系，例如，T可以为直线的长度的倍数。
在一些实施例中，显示设备中还可以配置将一种移动轨迹作为一个启动指令。例如，可以设定调节扬声器的音量的启动指令对应的移动轨迹可以设置为一个顺时针的圆环。例如，显示设备可以在确定控制装置在长方体空间中的移动轨迹映射到显示屏之后的移动轨迹为一个顺时针的圆环之后，则可以确定控制装置要进行调节扬声器的音量，显示设备还可以在显示界面中显示如图23所示的显示界面，然后可以进一步获取控制装置在长方体空间的移动轨迹映射到显示屏中的移动轨迹，若确定该后续的移动轨迹为一条向上的直线，则可以确定需要将扬声器的音量调高。反之，若显示设备在确定接收到调节音量的启动指令之后，进一步获取的移动轨迹为一条向下的直线，则可以确定需要将扬声器的音量调低。
在一些实施例中，显示设备还可以结合预先配置的移动轨迹与具体操作的对应关系与具体的应用程序包括的各类控制指令相结合，来确定需要执行的控制指令。例如，显示设备在通过目前一些视频应用程序播放视频时，可以响应于用户长按显示屏的操作，以倍速的形式播放视频。结合本申请提出的方案，显示设备可以在检测到控制装置处于长方体空间中的某一个位置超过设定时长时，确定对应的具体操作为长按显示屏的操作，然后显示设备可以结合视频应用程序自有的功能，确定需要执行的控制指令为以倍速的形式播放视频。在一些实施例中，显示设备在确定设定时长时，可以采用如下方式：
显示设备可以检测使用控制装置的用户的手臂摆动的线速度为f m/s，根据蓝牙的定位精度为D  m，确定设定时长T＝D/f*10 3ms。那么显示设备可以在确定控制装置位于长方体空间的某一个位置的时间超过T时，确定对应的操作为长按显示屏。
本申请提出的方案还可以应用于音频播放或者绘图的场景中，例如，可以预先建立在音频播放场景中调节音量的大小、切换歌曲等控制指令与控制装置的移动轨迹之间的对应关系。或者在绘图场景中，可以进行显示控制装置在长方体空间中的第一移动轨迹投影到显示屏上的第二移动轨迹，作为需要绘制的图像。
(4)与遥控功能配置关联的实施方式
在相关技术中，一般采用专门为显示设备配置的控制装置来实现对显示设备的控制。例如，通过遥控器控制显示设备等。在这种情况下，若控制装置丢失或者损坏，就会导致用户无法控制显示设备，或者用户只能通过显示设备上的少量按键来控制显示设备，使得用户的使用体验较差。本申请一些实施例提供了一种显示设备及控制显示设备的方法，提出了即使没有专用的控制装置，也可以采用具有收发蓝牙信号功能的蓝牙设备(比如手机等)来控制显示设备。解决了由于专用的控制装置丢失导致用户无法显示设备的问题。
本申请一些实施例提供了一种控制显示设备的方法。本申请提出的控制方法可以由显示设备来执行，例如可以参见图3示出的显示设备。或者，控制方法也可以由显示设备包括的蓝牙组件和处理器来执行。下面，结合控制显示设备的方法，首先以控制方法是由显示设备来执行的为例进行介绍。控制显示设备的方法流程具体包括如下步骤：
显示设备接收来自蓝牙设备的蓝牙信号。
在一些实施例中，显示设备中可以配置有多根天线，显示设备可以通过多根天线来接收蓝牙信号。
显示设备根据蓝牙信号，在空间中确定映射区域，以及在显示屏中显示用于实现控制命令的至少一个控件。
其中，映射区域中的每一个位置点均与显示屏中所显示的至少一个控件存在映射关系。例如，可以是映射区域中(1，2，3)这个点对应至少一个控件中的控件A。在一些实施例中，可以是映射区域中的多个点对应至少一个控件中的一个控件。继续上述举例，映射区域中(1，2，4)和(1，5，3)这两个点也可以对应控件A。
显示设备在检测到蓝牙设备位于映射区域内时，根据映射关系确定目标控件。
其中，目标控件可以是显示屏中显示的至少一个控件中的任意一个控件，目标控件与映射区域中的目标点对应，目标点指的是蓝牙设备的位置对应的点。
在一些实施例中，显示设备可以根据接收到的来自于蓝牙设备的蓝牙信号来确定蓝牙设备的位置。若检测到蓝牙设备的位置位于映射区域内时，则可以根据映射关系，确定蓝牙设备的位置点所对应的控件即为目标控件。
显示设备在确定与蓝牙设备的距离缩短时，执行目标控件对应的控制命令。
在一些实施例中，显示设备可以根据来自蓝牙设备的蓝牙信号确定蓝牙设备的位置，根据蓝牙设备的位置的变化情况来确定蓝牙设备与显示设备的距离是否缩短。
在另一些实施例中，显示设备还可以根据接收到的蓝牙信号的信号强度来确定蓝牙设备与显示设备的距离是否缩短。例如，可以在蓝牙信号的信号强度增大时，确定蓝牙设备与显示设备的距离缩短。
在专门配置的控制装置丢失或者损坏的情况下，只要有能够发送蓝牙信号的蓝牙设备，用户依然可以采用该蓝牙设备来实现控制显示设备。解决了由于控制装置不可用导致无法控制显示设备的问题。
在一些实施例中，在通过蓝牙设备实现控制显示设备之前，显示设备还可以首先确定没有接收到来自控制装置的控制命令。例如，显示设备可以在开机之后，先检测是否接收到来自控制装置的控制命令，若在设定时长内都没有接收到来自控制装置的控制命令，则可以通过蓝牙组件接收蓝牙信号。或者，另外一种可能的情况下，显示设备在开机之后，可以直接通过蓝牙组件接收蓝牙信号，并根据接收到的蓝牙信号确定发送该蓝牙信号的蓝牙设备的位置。在一些实施例中，显示设备再进行判断设定时长内有没有接收到来自控制装置的控制命令。若没有，则可以采用蓝牙设备来实现控制显示设备，例如可以参见如控制显示设备的方法所述的过程。为了便于理解上述方案，可以参见图24，为本申请一些实施例的一种确定控制显示设备的方法的流程图，具体包括：
S2801，显示设备开启。
在一些实施例中，显示设备可以响应于用户对于显示设备上的实体按键的操作，执行开机动作。
S2802，显示设备通过蓝牙组件接收蓝牙信号，并根据蓝牙信号确定发送该蓝牙信号的蓝牙设备的位置。
S2803，显示设备判断设定时长内是否接收到来自控制装置的控制命令。
若是，则继续步骤S2805，即，根据控制命令执行相应的操作。
若否，则继续步骤S2804。
S2804，显示设备采用蓝牙设备实现控制命令。
显示设备在确定一段时间内没有接收到来自控制装置的控制命令后，才启动采用蓝牙设备实现控制命令。避免了在控制装置可用的情况下通过蓝牙设备实现控制命令导致接收到的命令混乱，无 法确定所要执行的命令的问题。
在一些实施例中，显示设备启动采用蓝牙设备实现控制命令时，可以首先根据来自蓝牙设备的蓝牙信号确定映射区域。由于蓝牙设备距离显示设备越近，显示设备检测到的蓝牙信号的质量越高，但是如果蓝牙设备距离显示设备太近，则会降低用户的使用体验。所以，显示设备在确定映射区域之前，可以首先确定有效距离，并在有效距离的范围内构建映射区域。其中，有效距离的范围可以理解为以显示设备为球心，以有效距离为半径的球体。在一些实施例中，可以预先配置一个优选距离，即为了保证蓝牙信号的质量，显示设备与蓝牙设备的优选距离(超出该优选距离，接收到的蓝牙信号的质量会降低，则无法根据蓝牙信号确定蓝牙设备的位置)。并在检测到蓝牙设备与显示设备的距离小于或者等于该优选距离时，将此时蓝牙设备与显示设备的距离作为有效距离。在一些实施例中，显示设备可以通过计算接收到的蓝牙信号的信号强度(Received Signal Strength Indication，RSSI)来确定蓝牙设备与显示设备的距离，并在确定该距离小于或者等于预先设定的优选距离时，将该距离作为有效距离。示例性地，可以参见图25，为本申请一些实施例的一种设置有效距离的方法流程，具体包括：
S2901，显示设备计算当前接收到的蓝牙信号的信号强度。
在一些实施例中，显示设备可以在显示界面中显示预设的优选距离对应的优选信号强度(即，蓝牙信号在达到优选强度时，代表蓝牙设备与显示设备的距离达到了优选距离)。显示设备还可以在显示屏中显示当前检测到蓝牙信号的信号强度。例如，可以参见图26A所示的显示界面。
在一些实施例中，由于蓝牙信号的不稳定性，显示设备还可以获取一段时间内接收到的蓝牙信号的信号强度，计算该段时间内蓝牙信号的信号强度的平均值，将该信号强度的平均值作为当前接收到的蓝牙信号的信号强度。
S2902，显示设备判断当前接收到的信号强度是否大于优选信号强度。
若是，则继续步骤S2903。
若否，则继续步骤S2904。
S2903，显示设备将当前与蓝牙设备的距离作为有效距离。
在一些实施例中，显示设备可以根据蓝牙信号的信号强度确定蓝牙设备与显示设备的距离。例如，显示设备中可以预先配置有信号强度与距离的对应关系，并根据该对应关系确定计算出的强度所对应的距离。
在另一些实施例中，显示设备可以根据蓝牙信号确定蓝牙设备的位置，然后再通过计算确定蓝牙设备与显示设备的距离。例如，显示设备可以通过其包括的蓝牙组件接收来自蓝牙设备的蓝牙信号，检测蓝牙信号中包括的固定频率扩展信号(Constant Tone Extension，CTE)，获取用于定位的同相正交(In-phase Quadrature，IQ)数据。然后显示设备可以根据IQ数据确定蓝牙组件包括的每个天线组的相位差，然后根据每个天线组的相位差确定每个天线组的到达角。在一些实施例中，显示设备可以根据每个天线组的位置和每个天线组的到达角确定蓝牙设备的位置。最后计算蓝牙设备的位置与显示设备的位置的差值即为蓝牙设备与显示设备的距离。
S2904，显示设备在显示屏中显示提示信息。
其中，提示信息用于提示蓝牙设备的用户将蓝牙设备靠近显示设备。作为一种示例，显示设备可以显示如图26B所示的显示界面，以提示用户将蓝牙设备靠近显示设备。
显示设备在显示提示信息之后，可以返回步骤S2901，继续计算蓝牙信号的信号强度，直至计算出的蓝牙信号的信号强度大于预设的优选信号强度。
在一些实施例中，显示设备在确定有效距离之后，可以进一步通过界面交互的方式在有效距离的范围内确定映射区域。在一些实施例中，可以首先通过界面交互的方式确定检测区域，检测区域的范围大于映射区域，映射区域位于检测区域内。显示设备可以在确定检测区域后，采用设定的规则将检测区域的一部分作为映射区域。例如，本申请一些实施例提供的一种确定检测区域的方法流程，具体包括如下步骤：
显示设备在显示屏中显示用于引导用户进行位置校准的显示界面。
例如，显示设备可以在显示屏中显示如图27A所示的显示界面。图27A所示的显示界面中包括四个校准位置。
显示设备在显示屏中显示当前蓝牙设备映射到显示屏中的位置。
在一些实施例中，显示设备可以获取蓝牙设备垂直映射到显示屏中的位置。例如，可以从蓝牙设备所在的位置点向显示屏所在的平面作一条垂线，可以将该垂线与显示屏相交的点作为当前蓝牙设备映射到显示屏中的位置。在一些实施例中，显示设备可以在显示界面中显示圆点、箭头或者三角等来代指蓝牙设备的位置，例如可以参见图27B所示的显示界面。
显示设备在显示屏中显示用于指示进行校准的指示信息。
例如，以针对校准位置A进行校准为例进行介绍，可以参见图27C所示的显示界面。在图27C所示的显示界面中，显示了用于指示针对进行校准位置A进行校准的显示界面。
显示设备在检测到蓝牙设备位于校准位置时，保存蓝牙设备的位置以及蓝牙信号的信号强度。
例如，蓝牙设备位于校准位置A时，显示设备可以计算此时蓝牙设备的位置W1。在一些实施例中，可以采用上述图25中的步骤S2903介绍的方式来计算蓝牙设备的位置。在一些实施例中，显示设备可以获取此时蓝牙设备发出的蓝牙信号的信号强度R1。同理，当蓝牙设备位于校准位置B、C和D时，可采用同样的方式获取并保存蓝牙设备的位置和蓝牙信号的信号强度。
显示设备结合蓝牙设备的位置和蓝牙信号的信号强度确定检测区域。
在一些实施例中，针对四个校准位置，显示设备可以获取四组蓝牙设备的位置和蓝牙信号的信号强度，例如：
校准位置A：(W1，R1)，校准位置B：(W2，R2)，校准位置C：(W3，R3)，校准位置D：(W4，R4)。
显示设备可以结合位置和信号强度这两个因素确定检测区域。为了便于理解，参见图27D，为本申请一些实施例的一种检测区域的示意图，图27D中所示的长方体ABCDEFGH即为检测区域。图27D仅作为一种示例，本申请一些实施例对于检测区域的位置和形状均不作具体限定。
在一些实施例中，显示设备在确定检测区域之后，可以进一步根据预先配置的规则确定映射区域，映射区域可以为检测区域的一部分。为了便于理解，可以参见图27E，为本申请一些实施例的一种映射区域的示意图，图27E示出的长方体ABCDEFGH即为检测区域，示出的长方体B’BD’DF’FH’H即为映射区域。图27E仅作为一种示例，本申请对于映射区域在检测区域中所处的位置，以及映射区域的形状不作具体限定。
在一些实施例中，显示设备可以在确定检测区域和映射区域之后，在显示屏中显示用于实现控制命令的至少一个控件。下面，结合一些具体的场景对至少一个控件的显示方法进行介绍。
在一些实施例中，显示界面中包括的控件的数量和内容可以是预先设定好的，例如可以参见图28所示的显示界面，其中包括用于实现增大音量、减小音量、确认、返回主页、向左滑动、向右滑动、向上滑动以及向下滑动等控制命令的控件。在一些实施例中，显示界面中显示的各个控件与映射区域中的各个点可以存在映射关系。可以是映射区域中的多个点对应显示界面中的一个控件。例如，映射区域中的点A-点D可以对应第一控件、映射区域中的点E-点H可以对应第二控件等。在一些实施例中，各个控件与映射区域中的各个点可以存在的映射关系可以为：当显示设备检测到蓝牙设备位于映射区域的某一个点时，则可以认为蓝牙设备选中了该点对应的控件。
为了保证界面交互的准确性，避免误操作。在一些实施例中，显示设备在显示上述各个控件时，还可以使相邻控件之间间隔一定的距离。例如，可以参见图29所示的显示界面。在一些实施例中，相邻控件之间间隔的距离的长度可以是根据蓝牙信号的定位精度来设置的，任意两个相邻控件之间间隔的距离可以相等也可以不相等。
在一些实施例中，若至少一个控件一直显示在显示界面中，可能会遮挡显示界面所显示的其他内容。例如用户在观看视频时，若至少一个控件一直显示在显示界面中，可能会遮挡用户观看的视频的内容，使用户的观看体验较差。基于此，本申请一些实施例提出了，显示设备在确定蓝牙设备的位置位于映射区域内时，可以持续显示至少一个控件。若显示设备确定蓝牙设备位于映射区域外时，可以在显示至少一个控件达到设定时长后，不再显示至少一个控件，避免遮挡显示界面的其他内容影响用户观看。
在一些实施例中，若蓝牙设备的位置发生变化，而显示屏中显示的各个控件的显示位置可能就不再处于蓝牙设备的用户的正前方，使得用户通过蓝牙设备进行界面交互的过程中使用体验较差。例如，可以参见图30中的(a)所示的场景示意图。基于此，本申请一些实施例提出了一种界面交互的方案，显示设备在检测到蓝牙设备的位置不再处于显示屏中所显示的至少一个控件的正前方时，可以将至少一个控件在显示屏中的显示位置移动至蓝牙设备的位置的正前方以便于用户观看。继续上述举例，显示设备移动至少一个控件在显示屏中的显示位置之后的场景可以参见图30中的(b)所示的场景示意图。在一些实施例中，显示设备可以利用图25中介绍的有效距离来确定蓝牙设备的位置是否位于显示屏中所显示的至少一个控件的正前方。例如，显示设备可以判断蓝牙设备与至少一个控件之间的距离是否小于或者等于有效距离，若是，则可以确定蓝牙设备位于显示屏中所显示的至少一个控件的正前方。为了便于理解，结合具体的实施例对上述方案进行介绍。示例性地，可以参见图31，为本申请一些实施例的一种界面交互方法流程，具体包括：
S3501，显示设备根据来自蓝牙设备的蓝牙信号确定蓝牙设备的位置。
在一些实施例中，显示设备根据蓝牙信号确定蓝牙设备的位置的过程可以参见上述图25的步骤S2903中的相关介绍。
在一些实施例中，为了避免由于物件遮挡或者墙体反射等因素导致的计算得到的蓝牙设备的位置不准确的问题，显示设备还可以计算蓝牙信号的信号强度，将信号强度不满足设定要求的蓝牙信号剔除(例如可以设定将信号强度过小的蓝牙信号剔除)，采用信号强度满足设定要求的蓝牙信号来计算蓝牙设备的位置。
S3502，显示设备计算蓝牙设备与显示屏中显示的至少一个控件的距离。
例如，显示设备确定的蓝牙设备的位置为(1，3，6)，至少一个控件的位置为(0，0，3)，则显示设备可以计算这两个点之间的距离，即为蓝牙设备与至少一个控件之间的距离。后续为了便于描述，将该距离简称为距离A。
S3503，显示设备判断距离A是否大于有效距离。
若是，则继续步骤S3504。
若否，则不进行任何操作。
S3504，显示设备移动显示屏中至少一个控件的显示位置。
显示设备在移动至少一个控件的显示位置之后，可以返回步骤S3501，直至显示设备确定计算出的距离A小于或者等于有效距离。
显示设备可以根据蓝牙设备的用户所处的位置，来移动显示屏中显示的至少一个控件的显示位置，使得至少一个控件在显示屏中的显示位置可以保持在用户的正前方，提升了用户的观看体验。
在一些实施例中，显示设备在根据蓝牙信号确定了检测区域和映射区域，并在显示界面中显示用于实现控制命令的至少一个控件之后，就可以持续检测蓝牙设备的位置了。为了节约显示设备的计算资源，在一些实施例中，显示设备在检测蓝牙设备的位置时，还可以周期性地进行检测(例如，可以每间隔设定周期计算一次蓝牙设备的位置)。在一些实施例中，显示设备还可以针对蓝牙设备所处区域的不同而设置不同的检测周期。例如，当显示设备确定蓝牙设备位于检测区域之外时，可以设置每间隔周期T1进行一次蓝牙设备的位置计算。当显示设备确定蓝牙设备位于检测区域之内且位于映射区域之外时，可以设置每间隔周期T2进行一次蓝牙设备的位置计算。当显示设备位于映射区域内时，可以设置每间隔周期T3进行一次蓝牙设备的位置计算。其中，T1＞T2＞T3。
在一些实施例中，若显示设备检测到蓝牙设备的位置位于映射区域内，则可以确定当前蓝牙设备的位置的点对应的目标控件(可以理解为目标控件即为蓝牙设备所要选中的控件)。在一些实施例中，显示设备还可以对该目标控件进行特殊显示，以表明该目标控件被选中。例如，当目标控件为“音量+”时，可以将该目标控件显示为背景颜色加深等。在一些实施例中，确定目标控件之后，显示设备可以在确定蓝牙设备与显示设备的距离缩短时，执行目标控件对应的控制命令，并在确定蓝牙设备与显示设备的距离增大时，停止执行目标控件对应的控制命令。下面结合具体的实施例进行介绍，参见图32，为本申请一些实施例的一种实现控制命令的方法流程图，具体包括：
S3701，显示设备根据蓝牙信号确定蓝牙设备位于映射区域内。
S3702，显示设备计算蓝牙设备的位置和蓝牙信号的信号强度，并确定蓝牙设备的位置对应的目标控件。
S3703，显示设备判断与蓝牙设备的距离是否缩短。
在一些实施例中，显示设备可以根据蓝牙信号的信号强度来确定距离是否缩短。例如，显示设备可以在信号强度变大时，确定与蓝牙设备的距离缩短。在另一种可能的方式中，显示设备可以根据蓝牙设备的位置确定与蓝牙设备的距离是否缩短。
在一些实施例中，显示设备还可以在确定蓝牙信号的信号强度增大，且确定计算出的蓝牙设备的位置靠近了显示设备时，确定蓝牙设备与显示设备的距离缩短。
若是，则继续步骤S3704。
若否，则不进行任何操作。
S3704，显示设备执行目标控件对应的控制命令，并继续计算蓝牙设备的位置和蓝牙信号的信号强度。
显示设备可以根据计算的蓝牙设备的位置和蓝牙信号的信号强度确定与蓝牙设备的距离。
S3705，显示设备判断与蓝牙设备的距离是否增大。
若是，则继续步骤S3706。
若否，则返回步骤S3704。
S3706，显示设备停止执行目标控件对应的控制命令。
本申请一些实施例还提供一种计算机可读的非易失性存储介质，其上存储有计算机程序，该程序被处理器或者处理器执行时实现如上述任一方法实施方式。
本领域的技术人员可以对本申请进行各种修改和变型而不脱离本申请的范围。这样，这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些修改和变型。
