图 5为文件接收的显示系统示意图。 具体实施方式
下面结合附图对本发明进行详细的说明。 其中, 本例中, 接收共 享文件的共享设备为具有显示屏的终端, 如 PAD等平板电脑、 电视、 手机等。 同处于无线网络中的其他共享设备还包括具有无线互联功能 的定点设备, 即位置相对固定的无线终端, 如台式电脑、 上述电视、 打印机、 无线路由器、 或仅用于定位功能的装置如微型基站、 信号发 射器等。 下面, 以一 PAD 收到一电脑传输过来的文件为例, 对本发明进 行描述, 如图 1所示的文件接收的显示方法的流程, 包括以下步骤: 步骤 10: PAD 接收到处于同一无线网络内的一电脑发出的文件 传输请求, 建立与该电脑的无线连接。
对于无线连接的建立, 为公知技术, 故不再对无线连接建立的过 程进行赘述。
步骤 20: PAD确定所述电脑相对于该 PAD的位置关系, 从而确 定出该电脑相对于该 PAD的所在方向。
其中, 该无线网络内的设备可预先对各自所处的位置进行定位, 由所述 PAD根据自身的位置数据、 所述电脑的位置数据, 以及内置 的方向传感器所标定的参考方向, 计算出所述电脑相对于该 PAD 的 所在方向。 对于本步骤将在后文进一步进行详细介绍。
步骤 30: PAD #居所确定出的所述电脑相对于该 PAD的所在方 向, 确定出从该方向指向 PAD 中心的一轨迹, 并显示所接收的文件 以该轨迹进入 PAD的动画。
另外, 对于屏幕垂直的情况, 可以将所述要显示的画面翻转至竖 直方向,以在屏幕上显示,这尤其适用于电视等屏幕竖直放置的设备。 对于 PAD等屏幕非竖直放置的设备, 则也可如上进行相应的翻转或 投影变换, 将空间轨迹投影到所述接收方屏幕的到屏幕上。
例如, 处于水平方向上, 当所述电脑分别在该 PAD 的前后左右 方向时, 则在该 PAD上显示文件分别从该 PAD屏幕的上下左右方向 直线轨迹移入该 PAD。 再如, 处于水平方向上, 所述电脑在该 PAD 的左方向前一定角度时, 则在该 PAD上显示文件从该 PAD屏幕的左 方向上一定角度直线轨迹移入该 PAD。
另外, 还可以在所述直线轨迹的起始点, 即该 PAD 屏幕边缘对 应所确定出的角度的位置上显示所述电脑的标记, 如图标或电脑名称 或 IP地址等, 更加便于用户识别出信息源设备。 并当所显示的动画 结束后, 再隐藏所述电脑的图标。
对于同一个角度具有两台以上的共享设备时, 则进一步根据各个 共享设备的坐标 (或水平面投影的坐标) 计算出与该 PAD之间的距 离, 并对应所述不同距离的共享设备, 确定出上述直线摸轨迹的长度 值(即直线轨迹结束端点距离起始端点的远近) 。 此时, 用户便可以 根据直线轨迹的长短, 判断出信息源设备。
下面, 对上述步骤 20 进行详细说明, 首先介绍各个设备对各自 位置的定位步骤, 仍以所述 PAD的定位为例进行描述, 如图 2所示 的 PAD定位流程, 包括以下步骤:
步骤 211 : 当 PAD进入上述无线网络内, PAD与定点设备建立无 线连接。 定点设备获取该 PAD的 ID, 为该 PAD分配 IP地址并提供 给该 PAD。 定点设备将该 PAD的 ID和 IP地址存入其属性列表。 其 中, IP地址是为了区分各个设备, 也可以以各个设备的 MAC地址替 代。
定点设备中存储有该无线网络内各个共享设备的属性列表, 所述 属性列表用于存储无线网络内各个共享设备的型号、设备图标、 IP地 址和空间坐标, 以及定点设备自身的空间坐标。 其中, 在某设备位置 发生变化时, 该属性列表记载的该设备位置会相应的空间坐标的更 新。
步骤 212: 以定点设备的空间坐标为基准, 测算出该 PAD的空间 坐标。
定点设备的坐标相对固定, 故以定点设备为基准进行该 PAD 空 间坐标的测算。 该 PAD的空间坐标的测算步骤包括:
第一步骤: 计算至少三个定点设备到该 PAD的距离。
如图 3所示该 PAD与定点设备的位置示意图, 在本实施例中, 三个定点设备的空间坐标分别为 A ( Xa,Ya,Za ) 、 B ( Xb,Yb,Zb ) 和 C ( Xc,Yc,Zc ) , 在该三个定点设备上安装有红外、 蓝牙、 WIFI或超 声波等无线收发模块。 相应的, 在所述 PAD 中同样安装有对应的无 线收发模块。 可依据无线信号传输的衰减程度计算出信号传输的距 离, 例如依据接收信号的强度指示 ( RSSI, Received Signal Strength Indicator )公式 PR=PT/Sn, 可分别计算出上述三个定点设备与该 PAD 的距离 SA、 SB和 Sc。 其中, PR表示接收方无线信号的接收功率, Ρτ

第二步骤 2 S i: £€ c c c根据上述结果及上述三个定点设备的空间坐标计算该 PAD的空间坐标。 c、
假设该 PAD的空间坐标为 (Χ,Υ,Ζ) , 那么依据投影以及勾股定 理可得出下列计算式:

由上述三组计算式便可推导出该 PAD的空间坐标 (Χ,Υ,Ζ) 的表 达式为:
其中 άχ

Figure imgf000008_0003
由上述三组计算式便可推导出该 PAD的空间坐标 (Χ,Υ,Ζ ) 。 该步骤的计算可由 PAD 计算, 也可由定点设备进行计算, 上述 计算信号传输距离所需要的参数及计算 PAD 空间坐标所需要的参数 可通过之前建立的无线连接交互。
关于该 PAD 坐标的计算, 还可以由其他定位技术实现, 如设置 于屋顶或较高位置上的摄像头获取包括定点设备和该 PAD 的全局图 像, 通过定点设备的坐标, 结合图像分析该 PAD 的位置进行定位。 另外, 通过一个摄像头获取的图片可获得水平投影的各个共享设备的 投影, 通过两个及两个以上的摄像头, 则可计算出该 PAD 的空间坐 标。
步骤 213 : 将所述空间坐标添加至定点设备所存储的该 PAD所对 应的属性列表中, 并将该空间坐标由所述 PAD进行同步存储。
由此, 当 PAD收到步骤 10所述电脑的请求时, 则可向上述定点 设备请求获取所述电脑的空间坐标信息, 或者向所述电脑直接请求获 取该电脑记录的该电脑的空间坐标信息。
下面, 如图 4所示, 再对上述步骤 20中描述的 PAD确定出该电 脑相对于该 PAD的方向的步骤进行描述, 包括以下步骤:
步骤 221 : PAD收到步骤 10所述电脑的请求时, 根据所述电脑 的 IP地址或 MAC地址,向上述定点设备请求获取该电脑的空间坐标 信息, 或者向所述电脑获取该电脑记录的该电脑的空间坐标信息。
步骤 222: 根据获取的所述电脑的空间坐标, 自身的空间坐标, 以该 PAD为中心, 确定出所述电脑相对于该 PAD的水平面方向。
其中, 该 PAD 上设置有方向传感器, 如地磁传感器, 以标定出 参考方向。 所确定出的其他各个共享设备的空间方向相对地磁是不变 的, 从而, 无论该 PAD屏幕朝向哪个方向, 由于方向传感器的存在, 该 PAD都可以正确标定出其他各个共享设备的方向。
以该 PAD 空间坐标为原点, 通过坐标变换, 得出其他共享设备 相对于该 PAD 的空间坐标, 并设定一方向为参考方向, 如正北方。 进而 #居得出的空间坐标, 确定出水平面内所述各个共享设备以该 PAD为原点的所在角度。
其中, 各个共享设备的空间坐标进行坐标系转换时, 以该 PAD 的空间坐标(Χ,Υ,Ζ )为原点, 则空间坐标为 (X Y Z 的共享设备 相对于该 PAD变换后的坐标为 (ΧΛΥΛΖ^ ) , 其中, Xi^ Xi- X; Yi' =Yi- Y; ZJ ^ ZJ- Z, 进而才艮据坐标和三角函数即可计算出上述角 度。
可见, 上述空间坐标以及据此计算出的角度, 与该 PAD 朝向无 关, 即, 该 PAD在被水平面旋转屏幕时, 对于各个共享设备定位时, 始终是以空间坐标为参照进行定位的, 即不随该 PAD屏幕的旋转而 发生变化。
另外, 由于该 PAD屏幕是平面屏幕, 故, 对于上述角度的计算, 可将各个共享设备均投影到水平面上进行上述角度的计算 (通过该 PAD内置的重力感应器可确定出其相对于水平面的俯仰角,进行确定 出水平面投影, 此技术为公知技术, 故对该技术不再赘述) 。
或者, 直接根据该 PAD 屏幕俯仰角、 朝向, 将各个共享设备与 该 PAD屏幕中心的连线直接投影到该 PAD屏幕上, 作为动画中文件 移动的轨迹。
图 5还示出了对应的文件接收显示的系统, 包括:
方位确定单元 5 10, 用于确定发送方相对于接收方的位置信息、 方向信息。 其包括:
位置确定单元 5 1 1, 用于根据 RSSI技术, 或者图像处理技术的方 式来确定出发送方相对于接收方的位置信息。 和
方向确定单元 5 12, 用于根据确定出的位置信息计算出发送方相 对于接收方的所在方向。
轨迹确定单元 520, 用于才 据所确定出的方向信息确定出该方向 到屏幕中心的轨迹数据。 例如, 根据所确定出的方向信息确定出从所 述方向指向接收方屏幕中心的直线投影在接收方屏幕上的轨迹。
文件图标移动显示单元 530, 用于才 据所确定出的轨迹显示所接 收的来自发送方的文件沿该轨迹向接收方屏幕中心移动的画面。 发送方标记显示单元 540, 用于 #居所确定出的方向, 在屏幕四 周对应方向上显示发送方图标。
以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发明的精神和原则之内, 所作的任何修改、等同替换、 改进等, 均应包含在本发明的保护范围之内。
