People talking about augmented reality often refer to the words “tracking” and “markers”. What exactly are augmented reality markers? We want to give you a short explanation and a few examples of real markers.
In short: Augmented reality markers (AR-markers) are visual cues which trigger the display of the virtual information. Markers can be normal images or small objects, as well as GPS coordinates. They are designed to be recognized by the device camera or GPS. After a marker is recognized, its position or content triggers the associated virtual information.
In this module, we explain in more detail the different types of markers, and give you a few examples of the most common cases. We will also present the most frequent uses, as well as understand the devices used to detect them and how they do this. Finally, we will describe different factors that must be taken into account from the point of view of AR end users.
