We happily provide ASL interpreters for any performance if requested by a patron (we have to, and so do you [if you are in the USA]). What I was wondering is if there are any types of wireless subtitle devices like we have assisted listening devices. If there aren't we should totally invent some. Why do I ask? First off, finances. It costs the theatre $1K to have a pair of ASL interpreters come for one performance. If only one or two patrons request the interpreters, we only take in about $100 for their seats. As I said, we are happy to provide this service, and facilitating it is much easier since we are on a university campus. However, we always struggle with how to facilitate this service without detracting from the experience for the rest of the patrons and distracting the actors. So, I know that places like the Metropolitan Opera have individual seatback subtitle devices that can only be seen by the person sitting directly behind the device. So, is there a system on the market that can do this wirelessly? Having an easily deployable wireless system would allow us to accept any patron at any time, no advance notice would be required to book interpreters, not to mention the cost savings. If you know of an existing system, I would love a link or info. If you think we could invent one, that would be cool too!
