    • A system for controlling the playback of a recorded session utilizing a window acting as a player for playing back a timestream for a shared representation media, such as an electronic whiteboard. Timestream and event information for the session is captured by one or more recording devices. Playback of a session is performed under the control of a session access device which utilizes event information to create a user interface for controlling session replay. The user interface includes the window for playing back the timestream of a shared representation media. Each graphical object in the window is associated with one or more events (e.g. a creation event, an editing event, a move event or a deletion event). Selection of a graphical object enables playback time to be moved to the time for one of the associated events. Selection may also be made on an area of the window. This will enable the user to view all events related to graphical objects in the selected area (as some graphical objects may be erased or moved).
    • 一种用于利用用作播放用于诸如电子白板的共享表示媒体的时间流来播放播放器的窗口来控制记录会话的重放的系统。 会话的时间流和事件信息由一个或多个记录设备捕获。 在会话访问设备的控制下执行会话的回放,该会话访问设备利用事件信息来创建用于控制会话重放的用户界面。 用户界面包括用于回放共享表示媒体的时间流的窗口。 窗口中的每个图形对象与一个或多个事件(例如创建事件,编辑事件,移动事件或删除事件)相关联。 图形对象的选择使播放时间能够移动到相关事件之一的时间。 也可以在窗口的区域上进行选择。 这将使用户能够查看与所选区域中的图形对象相关的所有事件(因为某些图形对象可能被擦除或移动)。

    • An input system for controlling the position or motion of a cursor, three dimensions that uses x, z position for inputting two coordinates and tilt in a plane (x-y or z-y) to input a third (and possibly a fourth coordinate). The invention is moved about on a surface for inputting two of the dimensions and tilted to input the third. The amount or degree of tilt and the direction of tilt controls the input of the third dimension. The base of the hand held device is curved so that the device can be tilted even while it is moved in two dimensions along the surface of the tablet. Tilting can be along two orthogonal axes allowing the device to input four coordinates if desired. The coil can also have switched resistors controlled by mouse buttons connected to it which the tablet can sense being activated to allow clutching and selection operations like those of a conventional mouse.
    • 用于控制光标的位置或运动的输入系统,三维使用x,z位置输入两个坐标并在平面(x-y或z-y)中倾斜以输入第三(也可能是第四坐标)。 本发明在用于输入两个尺寸的表面上移动并倾斜以输入第三个。 倾斜的量或倾斜度和倾斜方向控制第三维的输入。 手持装置的基部是弯曲的,使得即使在沿着片剂的表面沿两个维度移动的同时该装置也可以倾斜。 倾斜可以沿着两个正交轴,允许设备输入四个坐标,如果需要的话。 线圈还可以具有通过连接到其上的鼠标按钮控制的开关电阻器,其中该平板电脑可以感测被激活以允许诸如常规鼠标的离合和选择操作。
