How Emotion Detection Works?

Emotion detection is like when you can tell how your friend feels just by looking at their face or hearing their voice.

Imagine you have a robot friend who wants to know if you're happy, sad, angry, or surprised. To do that, the robot looks at your face, listens to your voice, and sometimes even checks what you’re saying. It’s like when you play Guess Who?, you use clues to figure out who it is.

How the Robot Sees Your Face

The robot uses a camera to take pictures of your face, just like how you take selfies. Then it looks for things like your eyes, mouth, and cheeks. If your eyes are wide and your mouth is smiling, the robot might say, “You’re happy!”

How the Robot Hears Your Voice

The robot also has a microphone to listen to you. When you talk, your voice can sound different depending on how you feel. A loud and fast voice might mean you're excited or angry, while a slow and quiet one could mean you're sad.

It's like when you’re telling a story, your friend can tell if it’s scary, funny, or boring just by how you say it!
