However, for many people, supertitles interfered with their enjoyment of a performance, because they tended to find themselves following the titles and not giving their full attention to the stage.
This problem was solved by the development of an electronic libretto system, which utilizes individual screens placed on the back of each seat, thus allowing patrons either to view a translation or to switch them off during the performance.

The audience can decide to view videos, texts, theatre information, surveys, or ask for assistance just by touching his/her personal screen.
