Hyper-reality -part four
I know it’s been a while since I wrote an article. finally, I kicked off my procrastination and came back to finish the hyper-reality series :)
Types of AR targets
Types of targets the software can recognize have progressed from very simple markers for images and natural feature tracking to full spatial map meshes.
Marker
The most basic target is a simple marker with a wide border, advantage of marker targets is they’re readily recognized by the software with a little processing power and minimize the app is not working due to inconsistent ambient lighting.
Coded marker
Taking simple markers to the next level, areas within the border can be reversed for 2D barcode patterns. this way, a single family of markers can be reused to pop up many different virtual objects by changing the encoded pattern. Vuforia includes a powerful marker system called VuMark that makes it very easy to create branded markers.
Multi targets
With multitargeted, you can have virtual objects pop up for each marker in the scene simultaneously. markers can be printed and folded or pasted on geometric objects.
Text recognition

Some AR SDKs allow you to configure your app to read the specific text in specific fonts. Vuforia goes further with a word list library and the ability to add your own words.
Simple shapes
AR apps can be configured to recognize basic shapes such as a cuboid or cylinder with specific relative dimensions. it’s not just the shape but its measurements that may distinguish one target from another.
Object recognition
The ability to recognize and track complex 3D objects is similar but goes beyond 2D image recognition. Vuforia offers Object Scanner to create object data files that can be used for targets.
Geolocation
GPS tracking is not accurate when it comes to close-up -views of objects. but you can use it for catching pokemon.
