Create virtual rooms filled with information about key terms and concepts from the high school trigonometry curriculum.
Explore trigonometry in a new way with the Trigonometry 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 trigonometry curriculum.
Walk around in the augmented reality trigonometry 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.
Trigonometry Portal AR creates virtual rooms that are approximately 4 meters by 7 meters. It is best used in a welllit open space, perhaps in a school's auditorium or multipurpose room.
Be sure that your iPad allows access to the camera function by choosing Settings > General > Restrictions > Off.
