It seems unbelievable. Supertitles in one’s own language on Google Glass. Ready for wearable tech, OperaVoice shows at the same time the next standard for live events. On Glass will be read texts and any other content of interest to patrons. No annoyance for whom does not love supertitles or enlightened screens in the dark. The captions will be delivered on patrons’ Glass or on hire by the venue.
