Emotions

The R2-D2 Vocalizer contains an emotional AI powered by a dataset derived from R2's on-screen emotional progression. The AI tracks a stripped down set of Paul Ekman's core emotions:

• Happiness

• Sadness

• Anger

• Fear

These four emotions — and the gradients between them — encompass R2's emotional range. For example, R2 can feel sentimental by being sad and happy. He can feel sassy by being happy and angry. He can feel excited by being scared and happy.

The vocalizer begins in an emotionally neutral state. When an emotional stimulus or electrocution is triggered, the AI processes the stimulus and adjusts R2's emotional state. This new emotional state is reflected in the vocal response.

In the absence of stimuli, R2's emotional state will drift towards neutral at a rate dictated by the AI unless the Personality Chip Override is enabled.

Personality Chip Override

When the Personality Chip Override is enabled, R2's emotions are locked in place and will not shift over time or in response to stimuli.
