Augmented reality overlays images onto a live view from which device?

• A. A computer with a standard monitor.
• B. A smartphone or tablet.
• C. A virtual reality headset.
• D. A dedicated 3D display.

Answer: (B)

Augmented reality works by taking a live image of the real world from a camera and drawing digital content on top of that view in real time. The device that provides that live view is usually a smartphone or tablet, because these handheld devices include a camera, a screen to view the overlays, and motion sensors to keep the graphics aligned as you move. A virtual reality headset isn’t used for AR since it often blocks the real world and shows a fully digital scene. A computer with a monitor could do AR if you connected a camera, but it isn’t as portable or common as using a phone or tablet. A dedicated 3D display isn’t typically used to overlay onto a real-time world view.
