Read full descriptionHide full description
Learn geometry in a new way with the Geometry Portal AR. Use the camera view on your iPad to detect a flat surface and then tap the screen. Instantly a portal opens to a world filled with information about the terms and concepts that are part of the geometry curriculum. Walk around in the augmented reality geometry portal. Tap on the walls and other objects in the rooms to get more information and to hear Siri read aloud information about the selected item. Scroll through a list of terms related to the rooms, walls and objects in the portal. Geometry Portal AR creates virtual rooms that are approximately 4 meters by 7 meters. It is best used in a well-lit open space, perhaps in a school's auditorium or multi-purpose room. Be sure that your iPad allows access to the camera function by choosing Settings -> General -> Restrictions -> Off.

Have you ever wanted to see how a beam or bridge you encounter in everyday life reacts when load is applied? What if you could see these in your space at all angles, without having to specify material types, meshing or boundary conditions? STRUCT-AR utilizes finite element models pre-loaded into this mobile AR application that allows users to interact and engage with the models on their mobile device or tablet. This can be used as a complementary teaching tool for enhancing personalized learning wherein students can leverage the technology as a learning companion both within the classroom and outside to better understand structural behaviors and mechanisms that are challenging to convey in a traditional 2D learning environment. To use the app, you must allow it to access your camera. No identifiable data is stored on any server and you can revoke access at any time.
