The
software
application is the first of its kind in the world which can be used on
portable devices and allows users to customize sign language to their own
specific needs.
The
technology has the potential to transform how sign language users –
from the profoundly deaf to those who have lost hearing in later life –
communicate.
Computing scientists at Technabling, a spin-out company of the
University of Aberdeen, are behind the technology which aims to bridge the gap
between sign language and more standard forms of communication.
One of its
main focuses is to help young deaf people gain employment opportunities.
Dr.
Ernesto Compatangelo, a lecturer in Computing Science at the University of
Aberdeen, and founder and Director of Technabling said:
“The aim of the
technology – known as the Portable Sign language Translator (PSLT) - is to
empower sign language users by enabling them to overcome the communication
challenges they can experience, through portable technology.
“The user signs
into a standard camera integrated into a laptop, netbook, Smartphone or other
portable device such as a tablet.
“Their signs are immediately translated
into text which can be read by the person they are conversing with.
“The
intent is to develop an application - an “app” in Smartphone terms - that is
easily accessible and could be used on different devices including Smartphones,
laptops and PCs.”
The PSLT has the potential to be used with a range of sign
languages including British Sign Language (BSL) and Makaton.
The number of
people in the UK whose first or preferred language is BSL is estimated to be
between 50,000 (Action on Hearing Loss) and 70,000 (British Deaf
Association).
BSL is however, a general-purpose language and therefore poses
limitations for users, making it impossible for them to easily express certain
concepts and terms that are very specific or used only within particular areas
of society – for example education and the workplace.
To overcome
this, PSLT enables users to personalise sign language to their own individual
needs.
Dr. Compatangelo continued: “One of the most innovative and exciting
aspects of the technology, is that it allows sign language users to actually
develop their own signs for concepts and terms they need to have in their
vocabulary, but they may not have been able to express easily when using
BSL.
“Whilst the technology has the potential to transform the lives of all
sign language users, a key target market has been identified.
“Our research
is being funded by the UK Department for Business, Innovation and Skills*with
the specific remit to create technology to enhance the lives of deaf people with
special emphasis on post 16 learners, i.e., young people who are either in
education or training.
“The key intent is to enable sign language users of
this age, and beyond, to overcome the communication disadvantage they
experience, allowing them to fulfil their education potential and enter the job
market.
“The personalised aspect of the technology is crucial to making this
happen.
“For example – for a student who is being trained in joinery, there
is no sign in BSL which means “dovetail joint”.
“A student using PSLT can
create their own sign to mean “dovetail joint” allowing them to communicate
easily with their tutor or other students in their class, without the
limitations imposed when communicating solely with BSL.”
Sign language users
have inputted into the development and testing of the product since its
conception.

Technology which translates sign language into text
is being developed by scientists.
