    • Projector and camera arrangements are provided for use in electronic whiteboard systems. Specifically, the present invention provides projector and camera arrangements wherein the projector and camera share the same imaging optics. By sharing the same projection and camera optics, the distortions that affect the projection system are the same as those of the camera system. Thus, the calibration step required in conventional whiteboard systems where the projector and camera are separate, i.e., each having their own distinct optics and settings, is no longer needed. Further, the arrangements provided in accordance with the invention are self-aligning, even when lens distortions are large and even in the presence of strong perspective effects. The shared optics projector and camera arrangements of the invention also provide for dynamic zooming. In addition, various active and passive optical marker or lightpen designs are provided for use in electronic whiteboard systems.
    • 提供投影机和照相机布置用于电子白板系统。 具体地,本发明提供了投影仪和照相机装置,其中投影仪和照相机共享相同的成像光学元件。 通过共享相同的投影和相机光学元件,影响投影系统的失真与相机系统的失真相同。 因此,不再需要常规白板系统中投影机和相机分开,即每个具有其独特的光学和设置的校准步骤。 此外,根据本发明提供的布置是自对准的,即使当透镜变形较大并且即使存在强的透视效果时。 本发明的共享光学投影仪和照相机布置还提供动态缩放。 此外,还提供了用于电子白板系统中的各种有源和无源光学标记或光笔设计。

    • Embodiments of the invention are associated with crowdsourcing, wherein a computing environment comprising all of the tools and other resources required to perform a specified task can be made available to all prospective participants, as a virtual machine image. One embodiment of the invention is directed to a method associated with a particular task that is provided by a task requester, wherein the particular task is to be performed by means of a crowdsourcing process. The method comprises the steps of selecting a plurality of participants, wherein each participant of the plurality is qualified to perform the particular task, and specifying a computing environment that comprises a set of resources, wherein each resource is required to perform the particular task. A virtual machine image that contains each of the resources of the set is constructed, and is then made available for use by each selected participant of the plurality.
    • 本发明的实施例与众包相关联,其中包括执行指定任务所需的所有工具和其他资源的计算环境可以作为虚拟机映像提供给所有预期参与者。 本发明的一个实施例涉及与由任务请求者提供的特定任务相关联的方法,其中特定任务将通过众包进程来执行。 所述方法包括以下步骤:选择多个参与者,其中所述多个参与者中的每个参与者被限定为执行所述特定任务,以及指定包括一组资源的计算环境,其中需要执行所述特定任务的每个资源。 构成包含集合的每个资源的虚拟机映像,然后使其可供每个所选择的多个参与者使用。
