Realtà aumentata: Star Wars sbarca sull'iPhone. Pronti a una battaglia spaziale virtuale

guerre_stellari

Lo abbiamo sognato per decenni, guardando la nota della saga di Guerre Stellari: una battaglia spaziale in cui distruggere i caccia imperiali che invadono la nostra città a colpi di laser, nell’astronave Millennium Falcon, proprio quella guidata con perizia da Ian Solo, l’intrepido contrabbandiere di Star Wars interpretato da Harrison Ford.

Ed ora, tutto ciò è possibile, anche se si tratta di realtà aumentata. Si chiama Star Wars Arcade: Falcon Gunner, ed è un'applicazione che utilizza la fotocamera dell'iPhone (prossimamente anche della sua quinta versione e dell’iPod touch di quarta generazione) in modo da 'teletrasportarci' in una incredibile guerra contro le pattuglie dell’Impero.

Tuttavia, come prevede qualsiasi software in realtà aumentata, lo sfondo resta chiaramente quello reale: affacciati ad una finestra, in piazza, su un grattacielo, fa lo stesso.

Anche se, stando alle dichiarazioni degli analisti che hanno sviluppato il progetto, "presto oltre agli spazi circostanti" saranno disponibili "anche alcuni ambienti virtuali che ricostruiscono alcune famose scene della saga di George Lucas. A cominciare dalla battaglia contro la Morte nera, la temibile stazione dell’Impero Galattico, o da quella avvenuta sul pianeta Hoth".
