With gestural control, students could interact directly with complex visualizations. They could model chemicals or DNA. They could explore space (the app Exoplanet already allows them to do so). Or they could easily manipulate data visualizations to test different scenarios. Holz makes the analogy that people develop an understanding of basic physics by interacting with the world. By allowing virtual exploration to take on experiential qualities, gestural control could make the most abstract concepts real and intuitive.
