Levels of Interactivity in Intelligent Textbooks

1. Static Content Level - Basic text with minimal formatting
2. Structured Content Level - Content organized into meaningful structures
3. Visual Representation Level - Data and concepts presented visually
4. Basic Interaction Level - Initial interactive elements
5. Simulation Level - Dynamic modeling of concepts
6. Advanced Simulation Level - Complex, personalized interactions

Detailed Breakdown

Static Content Level

1. Text Block - Plain text in paragraph form
2. Enhanced Text - Text with basic formatting (bold, italic, headers)

Structured Content Level

1. List Structure - Bulleted or numbered lists that organize information
2. Definition Structure - Term-description pairs that clarify concepts
3. Tabular Structure - Information organized in rows and columns

Visual Representation Level

1. Static Visualization - Charts, graphs, and diagrams that don't change
2. Toggle Visualization - Charts with options to switch between different views
3. Process Visualization - Workflows and sequences shown with connecting elements

Basic Interaction Level

1. Animated Visualization - Visual elements with predetermined movement
2. Interactive Infographic - Clickable areas that reveal additional information
3. User-Controlled Animation - Animations with basic user controls (play/pause)

Simulation Level

1. Basic MicroSim - Simple interactive simulation with limited controls
2. Standard MicroSim - Simulation with multiple controls and realistic modeling
3. Data-Enhanced MicroSim - Simulation that captures user interaction data

Advanced Simulation Level

1. Adaptive MicroSim - Simulation that adjusts to user behavior or preferences
2. Personalized MicroSim - Simulation tailored to user's knowledge level
3. Immersive Simulation - Comprehensive 3D environment with complex interactions
