Profo Rubens Almeida,

Thank you for pushing forward.  We are truly blessed.

The history of the ISWA 2010 extends back to 1986.  You can read more here:

In principle, Valerie and I both support the inclusion of additional hand shapes.  We can easily support a dozen new hand shapes.  More than that and things become complicated.  I will need to do a statistical analysis of our current texts to see how many additional hand shapes we can fit the easy way.  The easy way could be available in the current SignPuddle and SignMaker software as soon as the new fonts are ready.

If you really need over 30 hand shapes, then things might become more complicated.  We would need to add an extension mechanism to the ISWA.  This would not be available in the current software without significant work.

Thanks again for this work.

The goals of the present research are to investigate, share, collect and register the Handshapes (HS) of the Brazilian Sign Language (LIBRAS) to the modality Writing of LIBRAS by the system SignWriting. It is about a proposal to complement the International Alphabet of SignWriting proposed by Valerie Sutton and Adam Frost in 2010.

This initiative originated from the need to remedy the lack of many graphemes (symbols) of Writing of LIBRAS-SignWriting, referring to LIBRAS’ Handshapes (HS) in the main software of textual production, transcription, and registration of LIBRA’s written form by the SignWriting system, such as SignPuddle and SignMaker software, among others developed by the Programmer and System Analyst Steve Slevinsky. This research is exceptionally relevant for the deaf Brazilian community because the majority of published works produced in LIBRAS’ written modality for the deaf public are developed through a computational system. That means, specific software is used that allows textual production of LIBRAS through the SignWriting system. Despite that, this software does not englobe all graphemes (symbols) of the SignWriting system referring to the graphic representation of LIBRAS’ HS, entailing in its turn, difficulties for writers, translators and researchers in this sense.

we propose the application of the second step which we developed in the form of a Public Consultation on an online platform. This involves sharing the present study with society as a whole, especially with the deaf Brazilian community that uses the LIBRAS’ written modality through the SignWriting system. In this process, we hope to incite many people to share other HS that, until now, are not present in this inventory or in the proposed inventory by Sutton & Frost either, the latter who is also available for consultation on the platform.

Therefore, the expected result with this study is that the investigated and catalogued HS by the collaborative work done through public consultation and its respective registers in this research are that they are evaluated and validated by the system’s inventor, Valerie Sutton and her team, to posteriorly be implemented in the main software of textual production, transcription, and registration of LIBRAS’ written form by the SignWriting system. In this perspective, all the Brazilian users of the Written Sign Language through the SignWriting system will be able to do any production in reference of the Handshapes, that means, without any preoccupations with the Handshape that will be used because there won’t be any past barrier that forced its users to take alternative means to do so.

To each Libras user, please send any handshape. We appreciate it.
