Here is an update on the project’s user interface. There are three sections.
The emotion wheel is an overview of the six key emotions. When you click on a level, the number on the tip of the petals will change.
The next section is the Sliders. These are similar to the emotion wheel, but more control is given to each expression amount. You can also switch to “face control” where you can change each part of the face individually.
The temperament section changes the flavor of the expression being shown. The interface is divided into the four temperaments: Sanguine, Choleric, Phlegmatic, and Melancholic. Or, more simply, Relaxed to Analytic and Aggressive to Peaceful.
In the lower left corner is the option to switch the character to see the same expressions on them. You can also rotate the character around.
