| <h1>STEM Interface Overview</h1> |
| </center> |
| <p>The STEM user interface is organized into three "perspectives", |
| <a href="perspectives/designer.html">Designer perspective </a>, |
| a <a href="perspectives/simulation.html">Simulation perspective</a> |
| and an <a href="perspectives/analysis.html">Analysis perspective</a>. A |
| perspective is a collection of "editors", "views", "menu bar", "tool |
| bar" and a "perspective bar". An editor is a sub-window used to |
| interactively modify one of STEM's components while a view is a |
| sub-window used to display information to a user. The menu bar contains |
| high-level menus for options and operations that can be selected by a |
| user, while the tool bar contains icons that if selected (clicked on) |
| cause STEM to perform actions. The perspective bar is used to switch |
| between STEM's perspectives. These are illustrated in the image in |
| Figure 1 below. |

| <p>Similarly in the image in Figure 2 below, is STEM's <a |
| href="perspectives/simulation.html">Simulation perspective</a>. Note |
| that it does not have an editor area. |

| A user can switch back and forth between the two perspectives by |
| clicking on them in the perspective bar. The views are grouped together |
| in different areas of the perspective. Clicking on the title of a view |
| displayed on its tab will bring that view to the foreground. Views can |
| be closed by clicking on the "X" next to their name, or opened from the |
| "Window" menu in the menu bar. Any view can be displayed in any |
| perspective, though each perspective has a default set it displays when |
| first created. |
