- The use of state machines in the Rive design tool enables the creation of interactive and dynamic animations.
-
User Interface and User Experience (UI/UX):
- Gamification elements, such as progress bars and skill-focused cues, serve as a guiding companion throughout the language acquisition journey.
- The strategic use of spaced repetition, with the progress bar intentionally set to 80%, encourages learners to revisit past material while advancing with new lessons.
-
Data and AI:
- Duolingo's custom AI models, including the Student model and Birdbrain model, create a personalized learning experience by analyzing user data and optimizing exercise selection.
