Researchers at the University of Calgary in Canada have developed a new tool called "Augmented Physics," designed to transform static physics textbook diagrams into interactive simulations, revolutionizing physics education.
This tool utilizes advanced computer vision technologies, such as Segment Anything and multimodal large language models, enabling teachers and students to semi-automatically extract diagrams from textbook pages and generate interactive simulations based on the extracted content.
"Augmented Physics" supports a variety of simulation types, covering Newtonian motion, optics, circuits, and looping animations. Users can select specific objects within the diagrams for segmentation through a simple creation process, manipulate these segmented objects, adjust parameter values, and interact dynamically with the simulation results.
These interactive visual outputs are seamlessly overlaid on textbook PDFs and presented through a web-based interface, allowing students to learn, experiment, and explore directly on the textbook without searching for external resources or starting simulations from scratch.
Researchers conducted a heuristic study with seven physics teachers, exploring four key enhancement strategies: augmented experiments, animated diagrams, two-way binding, and parameter visualization.
"Augmented Physics" allows users to directly manipulate textbook diagrams, such as changing the position of objects in an optical diagram or the resistance value in a circuit diagram, and observe real-time changes.
Additionally, the tool can convert static diagrams into looping dynamic animations, showing changes in physical processes over time.
"Augmented Physics" also enables two-way binding between parameter values in the text and the simulation, such as binding numerical values in the text to the compression properties of a spring, allowing the system to simulate scenarios based on updated values.
Furthermore, the tool can visualize parameter values in the simulation, such as displaying changes in pendulum angle over time through dynamic charts.
Researchers evaluated the system through technical assessments, usability studies (with 12 participants), and expert interviews (with 12 physics teachers). The results indicate that the system can facilitate more engaging and personalized physics learning experiences.
Experts believe that the system complements existing learning materials, such as videos and online simulators, rather than replacing them. While existing materials may be more suitable for prepared topics, this tool provides educators with a way to create on-demand and personalized learning materials tailored to specific situations, which is not well supported by current practices.
In the future, researchers plan to extend the system to broader areas of physics, investigate its potential in classroom applications, and explore mixed reality modes to enhance the physics education experience.
