    • The Pendulum Whiteboard Printer is a fully-automatic robotic device for marking or otherwise effecting whiteboards, pinboards, or other vertical surfaces. The physical device consists of an effector platform suspended by two suspension wires whose lengths are adjusted by motorized spindles mounted above and on either side of the board surface. The position of the effector platform is adjusted by winding and unwinding the wires. Electrical power is supplied to the effector platform through the suspension wires or through an on-board battery. Control of a pen and/or other apparatus on the effector platform is achieved through modulation of the power voltage. A further component of this invention is electronic and computational apparatus for controlling the device, which may include automatic visual interpretation and feedback from a video camera viewing the board and printer.

    • A graphical input and display system for creating and manipulating an abstract graphical image by decomposing it into abstract elemental objects and organizing the elemental objects into a set of perceptually coherent composite objects. The system includes an input device for entering the graphical image, such as a mouse or digitizer and electronic stylus, a display, and a function selection system for manipulating the graphical image. The system decomposes the graphical image entered onto the display into abstract elemental objects each consisting of one or more consecutive "on" pixels within the image. The system organizes the elemental objects into composite objects, which are abstract groups of elemental objects, such that each elemental object belongs to one or more composite objects and each composite object contains one or more elemental objects. The elemental and composite objects are linked in a lattice data structure stored in system memory. When a user manipulates the graphical image, the system creates new elemental objects in the manipulated region of the image, reorganizes all or part of the composite objects into one or more new composite objects, and updates the lattice data structure.
    • 一种图形输入和显示系统,用于通过将抽象图形图像分解为抽象元素对象并将元素对象组织成一组感知相干的复合对象来创建和操纵抽象图形图像。 该系统包括用于输入图形图像的输入装置,例如鼠标或数字化仪和电子手写笔,显示器和用于操纵图形图像的功能选择系统。 系统将输入到显示器上的图形图像分解为每个由图像内的一个或多个连续的“开”像素组成的抽象元素对象。 系统将元素对象组织成复合对象,它们是元素对象的抽象组,使得每个元素对象都属于一个或多个复合对象,每个复合对象包含一个或多个元素对象。 元素和复合对象在存储在系统存储器中的网格数据结构中链接。 当用户操纵图形图像时,系统在图像的操纵区域中创建新的元素对象,将全部或部分复合对象重新组织成一个或多个新的复合对象,并更新网格数据结构。
