etiquetAR is a web-authoring application designed towards learning purposes to support practitioners in the design of activities based on QR codes. This poster illustrates how etiquetAR QR codes were used to augment a University Campus as a support for a gamified tag-based learning activity. The QR codes generated change its behavior depending on the profile of the student interacting with the tag. The results show the successful application of etiquetAR in a real educational context.
