Abstract
Apparatus for providing closed captioning at a performance comprises means for encoding a signal representing the written equivalent of spoken dialogue. The signal is synchronized with the spoken dialog and transmitted to wearable glasses of a person watching the performance. The glasses include receiving and decoding circuits and means for projecting a display image into the field of view of the person watching the performance representing at least one line of captioning. The field of view of the displayed image is equivalent to the field of view of the performance. A related method for providing closed captioning further includes the step of accommodating for different interpupillary distances of the person wearing the glasses.
