## What is SignLexicon?

SignLexicon is a comparative dictionary between Italian Sign Language (LIS) and American Sign Language (ASL). It has been developed as a teaching aid within the LILS project to experiment Italy's first bachelor's degree for Sign Language International Mediators.
The project has been co-funded by the Italian Ministry for Universities and it is led by a partnership of the University of Parma (project leader), OSSMED Ets (coordinator) and SSML San Domenico University College in Fermo (executor).	
SignLexicon 1.0 includes around 3,200 entries: 800 LIS signs and their written Italian equivalent, and 800 ASL signs with their written English equivalent.
This freeware is available on the main operating systems for smartphones and tablets.
