In a recent episode of Dr Who, The Well, Deaf actress Rose Ayling-Ellis plays a Deaf character Aliss. Aliss is a survivor of some, at first unknown, disaster that has befallen a mining colony 500,000 years in the future. The Doctor and current companion Belinda arrive with troopers. Discovering Aliss is deaf they communicate with her using a nifty futuristic gadget of the troopers that picks up everything they say and converts it into text as they speak, projected in front of them. That allows her to read what they say as they speak.
Such a gadget is not so futuristic actually (other than in a group of troopers carrying them). Dictation programs have existed for a long time and now, with faster computers and modern natural language processing techniques, they can convert speech to text in real time from a variety of speakers without lots of personal training (though they still do make mistakes). Holographic displays also exist, though such a portable one as the troopers had is still a stretch. An alternative that definitely exists is that augmented reality glasses specifically designed for the deaf could be worn (though are still expensive). A deaf or hard of hearing person who owns a pair can read what is spoken through their glasses in real time as a person speaks to them, with the computing power provided by their smart phone, for example. It could also be displayed so that it appeared to be out in the world (not on the lenses), as though it were appearing next to the person speaking. The effect would be pretty much the same as in the programme, but without the troopers having had to bring gadgets of their own, just Aliss wearing glasses.
Aliss (and Rose) used British Sign Language of course, and she and the Doctor were communicating directly using it, so one might have hoped that by 500, 000 years in the future someone might have had the idea of projecting sign language rather than text. After all, British SIgn Language it is a language in its own right that has a different grammatical structure to English. It is therefore likely that it would be easier for a native BSL speaker to see sign language rather than read text in English.
Some Deaf people might also object to glasses that translate into English because it undermines their first language and so culture. However, ones that translated into sign language can do the opposite and reinforce sign language, helping people learn the language by being immersed in it (whether deaf or not). Services like this do in fact already exist, connecting Deaf people to expert Sign language interpreters who see and hear what they do, and translate for them – whether through glasses or laptops .
Of course all the above so far is about allowing Deaf people (like Aliss) fit into a non-deaf world (like that of the Troopers) allowing her to understand them. The same technology could also be used to allow everyone else fit into a Deaf world. Aliss’s signing could have been turned into text for the troopers in the same way. Similarly, augmented reality glasses, connected to a computer vision system, could translate sign language into English allowing non-deaf people wearing glasses to understand people who are signing..
So its not just Deaf people who should be wearing sign language translation glasses. Perhaps one day we all will. Then we would be able to understand (and over time hopefully learn) sign language and actively support the culture of Deaf people ourselves, rather than just making them adapt to us.
