ARLectio Treasure Hunt è una applicazione per fruire una Caccia al Tesoro Educativa in AR. Sfruttando la tecnologia della Realtà Aumentata (AR), unisce divertimento e apprendimento consentendo di sperimentare un'esperienza didattica unica e coinvolgente che si estende attraverso diverse discipline. Seleziona un percorso e risolvi gli enigmi delle tappe a cui è associato un contenuto educativo in Realtà Aumentata sotto forma di quesito. Per individuare ogni tappa ti verrà dato un indizio che ti aiuterà a trovare dove è celato il quesito che dovrai risolvere. I quesiti verranno quindi mostrati utilizzando tecniche di AR associati ad alcuni marker visuali posizionati in ogni tappa. In particolare, ogni quesito potrà essere formulato mediante un semplice testo, un immagine o un video. I marker visuali, che attiveranno i contenuti AR saranno posizionati nell'ambiente dal docente o da chi organizza la caccia al tesoro. I marker sono reperibili sul sito di supporto https://treasurehunt.pa.itd.cnr.it. In particolare, per maggiori dettagli e informazioni su come predisporre in modo semplice ed efficace e/o partecipare ad una caccia al tesoro mediante ARLectio TH si consiglia di consultare la sezione "Kit Caccia al Tesoro" del sito, dove saranno disponibili istruzioni per cerare una esperienza personalizzata o usufruire di materiale già disponibile mediante questa app.
