American Sign Language
But the use of Sign in books is almost lost for the use of the written language, meaning that much of the language that is Sign, including jargon, humour and other cultural nuances, is lost. It is obscured by the written language that doesn't contain the same set of nuances. It is like swapping English for French, not even British English for American English.
As with the remaking of foreign movies, not just the subtitling, there are different ways of interpreting events, representing events and reacting to them. These differences are what is lost between the use of Sign to communicate and the use of the written language.
This means that while books seem like the perfect answer to conveying stories from one hearing impaired person to another it isn't always the case. Like many other forms of story telling there are some stories that fit certain modes of telling better than others. So too are there stories best told in Sign rather than in the written language. In which case the best method of conveying these stories shifts back to being the visual formats such as movies and stage performances.
Again though, there is an issue. Many stories need to be shortened to be performed and in most cases when made into movies they are reduced to dialogue and action as the main methods of conveying the story. Much of what needs to be imagined is portrayed in full colour and life sized displays. This means that the imagination isn't worked nearly as hard as when a person is presented with black and white scribbles that need converting into a full world.
The upshot of all this is that there is no truly perfect medium for Sign stories other than in the story around the campfire format. Such stories pull on the imagination, can be long or short and are intensely visual. But such stories (not necessarily told around a campfire, obviously) are often unrecorded and unrecognised by the general public. So even this method of story telling is flawed.

Which leads me to a very small point on subtitles: They really, really are bad in some cases. White on white or yellow on yellow. Incorrect interpretations of the spoken words leading to gobbledegook written on the bottom of the screen (don't get me started with YouTube's subtitles...). Subtitles that scroll past too fast or too slow or even take up more than a third of the screen. There really need to be better standards all round. These problems were especially highlighted to me when I was sitting beside my hearing impaired Pop watching the TV shows of his choice. I could hear and read so I could pick out just how many mistakes there were, how delayed the feed was and how confusing it was to have feeds running at the bottom of the screen on football news while the subtitles were reading economic news. Only I knew which the reporter was actually speaking on, leading my Pop to wonder at the Chinese economists being so interested in football.
So the visual formats aren't perfect and Sign is left almost entirely as a language for communicating person to person, directly.
You'd also think there is a possibility of conveying Sign decently in writing by describing all the movements made but such conversations would take a fair while to write, needing more than one word to represent one word. So Sign is little used in writing without the interpreter acting like a narrator and spelling the movements out to the reader, again almost defeating the purpose of Sign except in the much needed representation of the hearing impaired in our stories. You simply cannot ignore a whole section of the population just because it is hard to write Sign.

Sign is still making headway into the world of visual media so there is likely lots of time for us all to witness how successfully it adapts and what new formats may arise. Sign isn't for every person who's hearing impaired but the vast majority of those who can learn it do. This means that Sign is here to stay and for any language that means constant change and adaptation. It will be exciting to see what happens next.
Note: I apologise for any rambling, I've a Doctor's certificate to prove I have an allowance for it but no, you can't see it. You'll just have to trust me.
