Manipulating Screen Space with {\em StretchTools}: Visualizing Large Structures on Small Screens

摘要: StretchTools is a set of tools for manipulating the screen space. The user interface uses metaphor stretching rubber sheet. basic tool in handle, which an one-dimensional rigid object fixed orientation, either horizontal or vertical. As handle placed on screen, engaged, and pulled, expands one side contracts other side. Graphical objects transform accordingly. type clamp. Clamps are used to impose constraints movement handles by joining with another. In this paper, we show how can be visualize large structures small screens selectively enlarging single multiple regions at time. Transformations achieved have number properties that alleviate problem user-disorientation due introduced distortion.
