An example repository created to demonstrate how to track gestures with ARKit and Unity3d
- To setup an expression go to the project tab in Unity3d > Right Click on any folder > Expressions > Create Expression
- Name the expression
- Increment the Size of "Blend Shape Ranges" to add a new face area to track
- Set the Lower and Upper Bounds
- Associate new expression with the Expression Manager "Expression Configurations" increment the size of the array to add a new expression association
If you have questions about this feel free to watch the YouTube video below where I go through this process in detail:
