Augmented reality (AR) combines digitally generated 3D content with real-world objects that users are looking at. The “virtual” computer-generated 3D content is overlaid on a view of the real world through a specialized display. All augmented reality technologies involve some form of display technology that combines real and virtual content – including headset devices, camera-enabled smartphones and tablets, computer-based webcams, and projectors displaying interactive images on a physical surface. These technologies support real-time tracking of hands, 3D objects, and bodies as they push on or touch virtual objects. This enables a more-natural interaction between the learner and the virtual content. AR technologies support learning by allowing learners to interact with 3D representations; they enable embedded assessments; they support groups of learners engaging with shared virtual objects; and they tap into a child’s natural inclination to play and experiment by moving around and touching and manipulating objects.
