The interface has been developed with QtCreator tool and it makes use of PyQt5 libraries to run the GUI.

• 

This package aims to improve the user experience with the stack. For that purpose, several functionalities that ease the interaction with the ROS API are included in the GUI:

• The general menu provides a fast view of projector status with LED indicators.

• CoordinateSystem and ProjectionElement submenus wraps the definition and control operations of projection elements: set active coordinate system, add projection element, scan targets, etc.

• Push buttons allow triggering the actions on projector.

The image below shows an example of projection element definition: user selects the figure type, fills in the fields with necessary data and press the add button. Next time the projection is started, this new figure will be projected.
