In my earlier article, I have explained the fundamentals of XR and the type of XR, and the popular devices in those XR types. ARVR is not the only about Head-Mounted Display(HMD) devices. There is an ever-growing list of Google ARCore supported smartphones/tablets and ARKit is being supported in recent Apple phones. But still, when when it comes to AR and VR devices, the first thing that comes in mind is head-mounted display devices (HMD), however, the newer mobile phones/tablets are now coming with AR/VR support with a minimal set of tools attached.
