The document discusses a study exploring the use of mobile augmented reality to support secondary education in Mexico. Researchers conducted interviews at a public secondary school to understand students' mobile phone usage and developed a prototype Android application to supplement textbook learning with 3D models, video, and audio. A usability test with 5 students found the application very easy to use and highly engaging, with students remaining focused on the educational content. The results suggest augmented reality on mobile devices can effectively support basic education in Mexico.
