The ProCalc user interface is optimized for screens with resolution 1600 x 1050 pixels or higher. Although the minimum resolution is 1024 x 768, screens with higher resolution are recommended.

**To launch ProCalc:**

- Windows **Start** menu >  **All Programs** > **Vicon** > **Vicon ProCalc #.#; ** or
- Double-click on the desktop icon, if available.

After a short time, the ProCalc window is displayed:

The main window is split into three parts:

- The left side contains the controls – where you choose what to process and how to process it.
- The top of the right side contains the 3D workspace – where ProCalc visualizes what you’re currently calculating.
- The bottom of the right side contains the Log – where ProCalc outputs relevant messages during your work.

ProCalc offers two main workflows:

- **Defining your calculations** You use ProCalc to define what you wish to calculate, and how ProCalc should calculate it.
- **Processing** You use ProCalc to execute pre-defined calculations on one or more trials.
