As of right now, augmented reality (AR) is the most useful EdTech since it can be used with standard smartphones and tablets without the need for additional hardware, making it ideal for interactive lessons, 3D models, and rapid concept visualization. VR is helpful but more constrained, primarily in training where headsets are available, simulations, and virtual labs (such as medical or engineering education). Due to its higher cost and setup complexity, XR is primarily used in advanced or enterprise-level learning, making it promising but still in its early stages.
