    • A graphical user interface (GUI) displaying a viewport includes a panning control region defined within an outer boundary of the viewport within the GUI. The panning control region includes multiple segments, each of the multiple segments corresponding to a panning direction, wherein a panning rate is indicated by a level of translucency of the multiple segments. A panning available region defined along the outer boundary of the viewport within the GUI is included. The panning available region indicates whether a source image extends beyond an edge of the viewport, and the panning available region is a subset of the panning control region. A method for panning an image through a viewport and a computing device are also provided.
    • 显示视口的图形用户界面(GUI)包括在GUI内的视口的外边界内定义的平移控制区域。 平移控制区域包括多个段,多个段中的每一个对应于平移方向,其中平移速率由多个段的半透明度指示。 包括在GUI内的视口的外边界定义的平移可用区域。 平移可用区域指示源图像是否延伸超过视口的边缘,并且平移可用区域是平移控制区域的子集。 还提供了通过视口和计算设备平移图像的方法。

    • A method for correcting a projection from a plurality of digital projectors is provided. The method includes receiving as an input a matrix which maps each pixel to be projected to a captured pixel that includes a row value and a column value and detecting a shift with respect row or column values in the matrix. The method further includes determining attributes of the shift, wherein the attributes include a type for the shift and an overlap length for the shift. A gradient length is determined from the overlap length. A gradient of pixel weightings is generated for each gradient length. The pixel weightings are uniformly sloping and are associated with pixels in the gradient length and neighboring pixels. Intersecting gradients re merged and a list that includes common points and diagonal points is created from the merging process. The method operations may be embodied as code on a computer readable storage medium.
    • 提供了一种用于从多个数字投影仪校正投影的方法。 该方法包括:接收作为输入的矩阵,其将要投影的每个像素映射到包括行值和列值的捕获像素,并且检测相对于矩阵中的行或列值的移位。 所述方法还包括确定所述偏移的属性,其中所述属性包括所述偏移的类型和所述偏移的重叠长度。 从重叠长度确定梯度长度。 每个梯度长度产生像素加权的梯度。 像素权重是均匀倾斜的,并且与渐变长度和相邻像素中的像素相关联。 相交渐变被合并,包括共同点和对角点的列表是从合并过程中创建出来的。 方法操作可以体现为计算机可读存储介质上的代码。

    • A method and system for providing technical support for networked devices includes a first client component on a networked device having a conferencing application to enable communication exchange with a second client component. A server component is configured to distribute video and audio data streams to the first client component and the second client component in a conference session. A conference channel communication connection is established over which the video and audio data streams are carried between the first client component, the server component, and the second client component, and a back-channel communication connection is established for transmission of diagnostic and status information. A service call is managed by a service center dispatcher, who connects a technician client and a networked device client in a multi-party conference hosted on one of a plurality of load balanced servers.
    • 用于为网络设备提供技术支持的方法和系统包括具有会议应用以使得能够与第二客户端组件进行通信交换的联网设备上的第一客户端组件。 服务器组件被配置为在会议会话中将视频和音频数据流分发到第一客户端组件和第二客户端组件。 建立会议通道通信连接,在第一客户端组件,服务器组件和第二客户端组件之间承载视频和音频数据流,建立用于传输诊断和状态信息的后向通道通信连接。 服务呼叫由服务中心调度员管理,服务中心调度员在多个负载均衡服务器之一上托管的多方会议中连接技术人员客户端和联网设备客户端。
