An incomplete list of AR devices

Let's take a quick look at some AR-capable devices. This should give us a slightly better idea of the different types of devices we can use and deploy to:

• The Meta 2 is a head-mounted display headset that uses a sensory array for hand interactions and positional tracking, it has a visual field view of 90 degrees, and a resolution of 2560 x 1440:

• AR displays can be rendered on devices resembling eyeglasses, such as the Google Glass:

• Another such device is the HoloLens:

• There is something called a head-up display, which is commonly referred to as a HUD. It is an alternate implementation of AR displays:

• There are many new devices being researched on and created all the time. Augmented reality is still in its infancy.

All throughout this book, we will create applications and games that are inspired by the definition of AR. Since there are four main aspects of AR, we will use those four aspects and create a specific application or game for that chapter. Since we have a finite number of sensors that are available for Android and iOS devices, some sensors will be utilized in multiple projects.
