- How does the computer "see" if we're happy, sad, or fraustrated? Facial recognition is a computer program that captures our image, analyze the geometry of our contour, and check with a database that contains other people's pictures to make a guess on who we are, and how we feel.  
+How does the computer “see” if we’re happy, sad, or frustrated? Facial recognition is a computer program that captures our image, analyzes the geometry of our contour (the edges or outline of our face), and checks with a database that contains other people’s pictures to make a guess on who we are, and how we feel.
 
- In order to make this invisible algorithm visible, we have prepared this [facial recognition example](https://editor.p5js.org/xinxin/sketches/-gbq9sNsC) in p5.js for you to try out. You will need to give permission to your browser to access your camera for this sketch to play.

- The facial recognition software traces our face, and assigns numbers to our contour as an attempt to understand our feelings. But how often does it get it right? We can test this out by picking one emotion from the [Wheel of Emotions](https://www.isu.edu/media/libraries/counseling-and-testing/documents/Wheel-of-Emotions-Handout-(3).pdf) and performing it in front of this [emotion recognition example](https://editor.p5js.org/jodiechifunyise/sketches/zdV2SqBiD).

 #### Let’s Discuss
 - Did you notice any differences between the emotion you chose from the wheel and the emotion deteced in the p5.js sketch?

+### Updating a value
+We can also update the value of a variable throughout our code. It can mean one value in a specific context, and then change its value in another.
+
+- Replacing the value of a variable
+    - Variables can update themselves with new information - ie. x = x+1; This means that x will keep updating to add 1 to itself.
+    - If using “let,” we can change the variable type. The same variable used for storing numbers can also update to be text or array of values.
