Using the interface

OpenSesame has a powerful graphical interface that consists of several components (Figure 1).


Figure 1. The OpenSesame user interface.

Toolbars and menubar

The menubar

The menubar (Figure 2) is shown at the top of the window, or, on some operating systems, is integrated into the border around the window. The menubar contains general functionality, such as saving and opening experiments, running experiments, etc.


Figure 2. The menubar.

The main toolbar

The main toolbar (Figure 3) is (by default) shown at the top of the window, just below the menubar. The main toolbar contains a selection of the most relevant functionality from the menubar.

The item toolbar

The item toolbar (Figure 4) is (by default) shown at the left of the window. The item toolbar contains all items, that is, all building blocks of an experiment. You can add items to your experiment by dragging them from the item toolbar into the overview area.

The tab area

The tab area is the central part of the window (Figure 5). The tab area is where item controls, documentation, important messages, etc. are shown. The tab area can contain multiple tabs, and functions much like a tabbed web browser.

The overview area

The overview area (Figure 6) is (by default) shown at the left of the window, to the right of the item toolbar. The overview area shows the structure of your experiment as a tree. You can re-order the items in your experiment by dragging them from one position to another in the overview area.

  • Shortcut to hide/ show: Ctrl+\

The file pool

The file pool (Figure 7) is (by default) shown at the right of the window. It provides an overview of all files that are bundled with the experiment.

  • Shortcut to hide/ show: Ctrl+P

The debug window

The debug window (Figure 8) is (by default) shown at the bottom of the window. It provides an IPython interpreter, and is used as the standard output while an experiment is running. That is, if you use the Python print() function, the result will be printed to the debug window.

  • Shortcut to hide/ show: Ctrl+D

The variable inspector

The variable inspector (Figure 9) is (by default) shown at the right of the window. It provides a list of all variables that are detected in your experiment. When you are running an experiment, the variable inspector also provides a real-time overview of variables and their values.

  • Shortcut to hide/ show: Ctrl+I
