Scope of the product
Even with the substantial progress achieved with the emergence of sign languages, the integration of people with hearing loss society still finds obstacles. Mainly because most people do not know this language thus becomes necessary to improve and facilitate this integration. Thus, this project aims to design a system that can translate sign language Parle complete (LPC) in a textual language. This will make communication possible between speakers and non-speakers of the LPC, without the need of interpreters.
