- SignWriting is phonetic
- Flexible representation of space
- Can be handwritten
- A graphical language in itself
- Grapheme classes: HAND, HEAD, DIAC, ARRO, STEM, ARC
- Tags for grapheme shape and graphical variations
- Tags for spatial transformations (rotation, reflection)
- Movements decomposed into segments
Corpus
The VisSE Corpus is a publicly available collection of instances of Spanish SignWriting.
- 982 logograms (transcriptions of signs)
- 6060 graphemes (each of the symbols: hands, faces, movements…)
- Manually annotated
Quevedo
Quevedo is an open source library and application for annotating and automatically processing corpora of graphical languages.
VISSE APP
The representation encoded in the annotation, and the data we have collected in the corpus, allows us to build an automatic recognition of SignWriting pipeline using deep learning.
This recognition is used in a web application that explains (in Spanish) the meaning of SignWriting transcriptions.
VISSE Project
“Visualizando la SignoEscritura” (Visualizing SignWriting) had as goals the creation of tools for the easier use of SignWriting in the digital world.
Future Work
- Collect and annotate more data.
- Convert to and from other representations, like FSW or SWML.
- Process global meaning and convert to and from HamNoSys or SiGML.
