Doremi CaptiView is a small 3-line electronic caption display for movie theatres. It can be inserted into your seat's beverage holder, and receives the captions wirelessly. Since the captions are displayed without the need to adjust to a rear-projector, users may have greater seating choices and viewing ease. You'll need to check if CaptiView is available in a theatre near you.
Deaf Tech News has a review and a video of CaptiView in action.
