SignAll is pioneering the first automated sign language translation solution, based on computer vision and natural language processing (NLP), to enable everyday communication between individuals with hearing who use spoken English and deaf or hard of hearing individuals who use ASL. The SignAll prototype is currently able to translate part of an ASL user’s vocabulary. According to research professionals and leading tech companies, SignAll is the best automatic sign language translation system available worldwide. We believe that the boundaries between hearing and hearing impaired people can be removed by technology. We are working for a world where the Deaf/HoH can communicate with other people spontaneously and effectively - anytime, anywhere.
Over 100 million people - more than 1% of the world’s population - are unable to hear. Being deaf from birth or childhood, many of these people use sign language as their primary form of communication.
There are several hundred sign languages around the world and these also have their own dialects. One of the most common of these is American Sign Language (ASL). More than 500,000 people use ASL in the US alone, and millions more use it worldwide.
Most hearing people don’t know that written English is only the second language of people who are born deaf. Although they can settle mostly everything in writing, there might be such official situations in which the cooperation of a sign language interpreter is necessitated as they prefer communicating on their first language – sign language.

The translation appears on the computer
The prototype uses 3 ordinary web cameras, 1 depth sensor and an average PC.
The depth sensor is placed in front of the sign language user at chest height and the cameras are placed around them. This allows the shape and the path of the hands and gestures to be tracked continuously. The PC syncs up and processes the images taken from different angles in real-time.
Having identified the signs from the images, a natural language processing module transforms the signs into grammatically correct, fully formed sentences. This enables communication by making sign language understandable to everyone.
The prototype has a modular construction, which allows components to be replaced as technology improves. This means that SignAll will be become faster, smaller and even more accurate over time.
Most people think that sign language is just about different hand movements. Sign language is actually much more complex than that.
Research has shown that fully automated sign language recognition requires a solution that combines all of the important factors. That is why - according to computer vision experts - the automated interpretation of sign language is one of the biggest challenges for technology.
Sign language has many different aspects that are combined to convey the intended meaning. These are:
Manual components (also called parameters) are the bases of signs. Their significance is so obvious that most (hearing) people think they make up the entirety of sign language. Signs have four (manual) parameters:
-Handshape: arrangement of fingers to form a specific shape
-Movement: characteristic movement of the hands
-Orientation: the direction of the palm
-Location: place of articulation: can refer to the position of the hands itself (relative to each other) or position of markers (e.g. Fingertips) relative to other places (chin, other wrist, etc.)
Facial expressions, also referred to as non-manual components, convey important grammatical meaning too. They are formed from two components: upper part (eyes, eyebrows: nms – non manual markers/signals) and lower part (mouth and cheeks: mms – mouth morphemes)
Just like with spoken languages, there are different levels and manners in which sign languages can be used to communicate. These are referred to as registers that can be intimate, consultative, casual, formal, cold and distant, though the relevance of the last one is still debated. Signing also has different levels of politeness: not all signed phrases are polite/proper in all situations.
Prosody is the elusive component of languages that subtly shapes the way we say what we say. It incorporates, among other things, the setting of rhythmic and intonational features that allow us to perceive the ways linguistic units are combined. In asl, this is realized in a visual-spatial manner, involving head and body movements, eye squints, eyebrow and mouth movements, the speed and formation of signs, pacing, and pausing. Such impalpable components are often found difficult by interpreters to comprehend.
Using space is a powerful tool in sign languages. It can be used to visually represent measures and arrangements of the objects and concepts in a dialogue.
