The augmented reality introduces us into a world that comes alive suddenly with the help of the camera of our tablet or phone. With marker, without marker or using geolocation, we have many ways to enter this virtual world.
The different types of user interactions help to discover this digital world.
The visualization of augmented reality can be achieved by several means:
– AR based on a marker
– AR without marker /markerless AR
– geo-based augmented reality /location based AR
AR based on a marker
The user must orientate the camera towards a precise marker to make the 3D image appear on the screen. The connection is created between the digital world and the real world by using a code hidden in an image, in a text or an object for example.
These tools must be very distinctive and recognizable by the camera. Just like a logo, a bottle or a poster.
We just have to find a place (flat, without furniture or other elements) where the visualization can be done freely.
This allows us to choose the location of the virtual object and test how it might appear in another environment. A very interesting initiative is, for example, the operation of the Ikea AR catalog. With the help of their application, you can select each piece of furniture and “imagine” them on their final destination at home.
The application recognizes the location of the user. For this, it is necessary to activate the location services via a mobile internet network. Among other things, this tool can be very useful for displaying directions or road signs. Among others, Pokemon Go is also based on this technology.
