AR can enhance the real world in real time by adding virtual objects such as a medical visualisation of the human body for an anatomy course, augmenting the visual acuity for learners with poor vision, and has grown to encompass all subjects. Simply reading about topics such as Geometry and Anatomy can help a learner become cognisant of a topic. AR allows for learners to see and manipulate 3-D solids (tetrahedron, icosahedron etc) or to perform a virtual dissection of the human body. The AR experience can be displayed through handheld devices such as a smartphone, a head mounted display (HMD), or even with an augmented reality headset. Here’s a example of me showing AR e-Book that was created by my wife’s students in Anchorage, Alaska.
