Sign Language / devices

The number of deaf people worldwide is about 0.1%. In every thousand people, there would be a person using the sign language to communicate. However, in sign language, there are two Achilles' heel. Firstly, the world does not use a common sign language, countries take into account their own language to develop and express a different way of sign language. Now with the development of a variety of sign language, there are hundreds of different sign language in the world’s deaf society in general. Secondly, only deaf people and members of the organizations use sign language to communicate. The result is that people who use sign language build an invisible fence between themselves and the normal people.
This design use sensing technology to monitor the deaf's hand movements (sign language) and monitor their corresponding position. After system identification, this design then communicates with normal people by speaker tools or mini-speakers (headset).
The design innovation lies in the following three points. First, the design is for the hearing-impaired and normal humans, which is an expansion to the sign language user's friends. Secondly, the design considers the psychological level, using micro-speakers (headphones). Third, due to the degradation of the human body and medical technology, at least 5% of the people in the world have hearing obstacles which affect their lives (most in the elderly, in other words one person for every 20). This design can effectively improve this dilemma.
