    Abstract: Apparatus for carrying out a spatial transform between information in two displays is described. Where one display is a graphical input tablet with an overlay forming graduations for the tablet, a point may be selected using a stylus and a corresponding point for example in a C.R.T. display may be intensity emphasized. The co-ordinates of the selected point are combined and the resulting number is compared with a number related to the position of a data item in a series of such items giving rise to the C.R.T. display. The positions of the data items in the series are arranged to give the required spatial transform when the number relating to position in the series equals the number formed by combining the co-ordinates of a selected point.

    Abstract translation: 描述了用于在两个显示器中的信息之间执行空间变换的装置。 在一个显示器是具有用于平板电脑的覆盖层形成刻度的图形输入平板电脑的情况下,可以使用触笔和例如C.R.T.中的对应点来选择点。 显示可能会强调强度。 将所选点的坐标组合,并将得到的数字与与一系列产生C.R.T的一系列数据项的位置相关的数字进行比较。 显示。 当与序列中的位置相关的数量等于通过组合所选点的坐标而形成的数量时,该系列中的数据项的位置被布置成给出所需的空间变换。
