  Sign Language is used to facilitate the communication between Deaf and
non-Deaf people. It uses signs-words with basic structural elements such as
handshape, parts of face, body or space, and the orientation of the
fingers-palm. Sign Languages vary from people to people and from country to
country and evolve as spoken languages. In the current study, an application
which aims at Greek Sign Language and English Sign Language learning by hard of
hearing people and talking people, has been developed. The application includes
grouped signs in alphabetical order. The user can find Greek Sign Language
signs, English sign language signs and translate from Greek sign language to
English sign language. The written word of each sign, and the corresponding
meaning are displayed. In addition, the sound is activated in order to enable
users with partial hearing loss to hear the pronunciation of each word. The
user is also provided with various tasks in order to enable an interaction of
the knowledge acquired by the user. This interaction is offered mainly by
multiplechoice tasks, incorporating text or video. The current application is
not a simple sign language dictionary as it provides the interactive
participation of users. It is a platform for Greek and English sign language
active learning.
