This device consists of a reflective plastic panel mounted on a flexible stem that is placed in the cupholder in movie theatres. The device allows the hard of hearing and deaf viewer to read the transcript of the voices through the window. It is sometimes necessary to sit in a certain area of the theatre to get the best angle for viewing the text. Other patrons do not see the captions. You will need to call the movie theatre to find out if the movie you want to see will be captioned.
