Limited interactivity in videos: While videos offer a dynamic representation, they lack the interactivity crucial for intuitive learning and experimentation. Lack of instructional scaffolding in online simulators: Existing simulators often lack the context and guidance found in textbooks, making them challenging for novice learners. Misalignment and distractions from external content: Sourcing external resources like YouTube videos can introduce inconsistencies with classroom materials and lead to distractions.Solution: Augmented Physics, an interactive learning toolAugmented Physics is a machine learning-integrated authoring tool designed to address these challenges. The system enables users to: Semi-automatically extract diagrams from textbooks: Leveraging advanced computer vision techniques like Segment-Anything and Multi-modal LLMs, users can easily isolate and segment elements from textbook images. Generate interactive simulations based on extracted content: The segmented images are converted into simulation-ready objects, allowing for dynamic manipulation and real-time feedback. Seamlessly integrate simulations into textbook pages: The interactive simulations are directly overlaid onto the textbook PDF, providing a contextualized and integrated learning experience.Four Key Augmentation StrategiesInformed by a formative study with physics instructors, the authors implemented four key augmentation strategies: Augmented Experiments: Users can manipulate textbook diagrams and observe real-time changes based on physics principles. For example, adjusting the position of a lens in an optics diagram or modifying resistance values in a circuit. Animated Diagrams: Static diagrams are converted into looped animations to demonstrate dynamic processes. This can involve animating an object's trajectory or visualizing wave propagation. Bi-Directional Binding: Linking parameter values from text to the simulation allows users to modify values within the text and observe real-time effects on the simulation, and vice-versa. Parameter Visualization: Users can visualize selected parameter values through dynamic graphs, providing insights into changing variables like velocity or energy.Technical Evaluation and User StudiesThe system was evaluated through technical evaluations, a usability study with 12 participants, and expert interviews with 12 physics instructors. Key findings include: High success rate for object segmentation: The system achieved an 86% success rate in accurately segmenting objects from diagrams. Varying success rates across simulation types: The overall success rates for generating functional simulations without modification were 64% for kinematics, 44% for optics, and 40% for circuits. Positive user feedback: Users found the system intuitive and engaging, particularly appreciating the Parameter Visualization and Bi-Directional Binding features. Complementary role to existing resources: Experts viewed Augmented Physics as a valuable tool for personalized learning and self-led exploration, complementing rather than replacing existing online resources and live experiments.Limitations and Future DirectionsThe paper acknowledges several limitations and outlines future research directions: Scaling to more complex concepts and broader domains: Future work will focus on expanding the system's capabilities to handle more complex physics topics and diverse diagram styles.
