The National Theatre is one of the three most prominent publicly funded performing arts venues in the UK.
The BT-300 smartglasses feature Epson's silicon-based OLED digital display technology, enabling mobile augmented reality experiences. They are also the lightest binocular see-though smartglasses to date.
A statement from Epson said the device was lightweight and comfortable enough to be worn for an entire performance. Users could change positioning, size and colour of captions to suit themselves.
Epson said the smartglasses had a quad-core Intel Atom X5 processor and Android 5.1, enabling efficient rendering of complex 3D experiences.
An upgraded 5 megapixel front-facing camera and on-board sensors enable the Moverio BT-300 to determine where objects resided in the real world.
The Si-OLED projection system then renders and locks 3D content to these objects, with no display background or edges in the field of view.
The trial is set to run until October 2018. The smartglasses can be bought for $1199.
