I used an AR service 12 years ago for a leaflet. Since then I have used several platforms but wouldn't dare to invest in one because there were app dependent. When MARVIN XR came along I thought that this was too good to be true. And yes, it is true. Device-independent through a browser. I subscribed without hesitation although I am not an expert. So far, MARVIN XR support is amazing even on weekends. The interface is friendly and I feel very secure that I will integrate this technology into our book publications. It will also give our company the opportunity to sail into future technologies and experiences.
