Face glyphs and Software that Transcribes Videos into SignWriting

SignWriting List
August 31, 2014

Hello Maria, Fabrizio and Stefan -
I believe you are asking for corresponding photos or drawings that could be placed side by side with each Facial Expression symbol in SignWriting?

There have been others who ask for this too, and we have considered doing this, but the problem is that the human face is very different from person to person, and I personally cannot even do all the facial expressions that are possible to write in SignWriting. Most people can’t either ;-)

We have had some photos taken in the past to use in this way, but not everyone could recognize in the photos exactly what the position was. This proves one fact that I had to learn over time…we are not just writing what we see…we are also writing what we feel, and what is considered necessary facial expressions for the understanding of the signs…not all facial expressions are needed. When you transcribe videos you need to know the difference between the facial expressions that are needed and the facial expressions that are not needed…that is not easy, with or without automation.

SignWriting has many aspects. It is a handwriting. It is expressing signer’s expression from their own perspective. That is the Expressive Viewpoint which is our standard.

But as you know for a decade we wrote Receptively. I was given an assignment, back in 1974, at the University of Copenhagen, to write what I saw people sign (and gesture) on a videotape of both hearing and Deaf people. The project was “writing the difference between hearing person’s gestures, and the movements of Deaf people signing Danish Sign Language”…so you can imagine the Deaf people were expressing their language and the hearing people were supporting their spoken language with minimal gestures…that was my beginning with writing signs and developing the beginning of SignWriting and it was through that project that I realized that the sign languages of the Deaf are real languages and it was clear that the hearing people did not have a sign language, but were using gestures to support their spoken language.

But being the hearing person I am (smile), I made the mistaken assumption that when we started to write real sign languages, that we should write from videotape and write exactly what we see…not feel. That came from the fact that I did not know the languages I was writing from videotape. I felt I could not impose my lack of knowledge on the writing, so I made a strong rule that we just write what we see, and it was Receptive, from 1974 to 1984.

But Receptive writing is not the same as Expressive writing - there are larger differences than most people realize…Later it was our Deaf staff, Lucinda O’Grady and Meriam Ina Schroeder, who requested switching from Receptive to Expressive in 1984, after three years writing articles in ASL in the SignWriter Newspaper in the Receptive, they became fed up with Receptive and demanded Expressive and I am glad they did!

They explained in a meeting in 1984 that they were really writing from their own experience, and were not writing from videotape…and when we write Expressively, which is the standard now, we write what we FEEL too… My immediate response was “what about Facial Expressions? how can we “see Facial Expressions” if we are writing ourselves?” and Lucinda explained it is what we “feel” while we are signing and writing that matters to a person fluent in writing ASL...

Which brings us back to video transcription - Video transcription fits well with Receptive, but nonetheless, most people I know use the Expressive to transcribe video because sooner or later the transcript must be in the Expressive for others to read... so most people write the videos in the Expressive from the beginning…

And Facial Expressions truly are based on a combination of what we see and what we feel…so the photos you are needing are harder because not all facial expression photos really portray what a person feels while they are signing…

So here are my questions to you Maria and Fabrizio…

1. Are you creating software that does an automatic transcription of sign language videos into SignWriting?

2. What is the name of this new software so I can refer to it easier? ;-)

3. Are you developing the software to transcribe videos in the Recpetive or the Expressive or both?

Val ;-)

For this reason, in oprder to reliably reproduce face expresions through the corresponding glyphs, we would need a kind og "glossary". i.e., a table of correspondence between real face images and glyphs.
