DILSE is a Spanish Sign Language (LSE) dictionary, developed by the Vodafone Spain Foundation with the knowledge and experience of the CNSE Foundation.

It is an application focused on learning LSE and that allows quick and easy access to more than a thousand definitions. It shows the correspondence between words and the most common signs of everyday life. 

The CNSE Foundation is an organization with a long tradition in the elaboration of Spanish sign language dictionaries and they are the ones that have contributed with the help of deaf experts and interpreters the contents.

The application also has a side menu, from which you can directly access the words of a specific letter. 

List of words with direct access by letter

An appreciable issue, it seemed to us to be able to identify the most common words, and include them in a list of "Favorites", to allow more agile access to them:

Vodafone Spain Foundation has put special focus on this aspect, offering an inclusive application for deaf people and people with different technical abilities. The potential user of the DILSE application that we value from Orientatech, is a person in the learning phase of the LSE or, a signatory who needs a dictionary such as that of the Royal Spanish Academy, with access to definitions in Spanish Sign Language.

Social valuation:

The DILSE application has been validated for two months on a Samsung J7 terminal and the tests have been carried out during FESORCAM's basic summer training in Spanish Sign Language. The impressions in this scenario have been very positive, the usefulness of the dictionary has been highly valued and the remarkable factor of DILSE is its portability in a mobile application that you can have installed on any Andorid phone. In parallel to this validation, other Sign Language dictionary platforms have been identified, such as the web Sematos or the youtube channel of LSE Easy, which have more definitions and linguistic structures than DILSE. After social validation, we can clarify that the list of words remains limited, and it would be essential to expand it in order to maintain its usefulness. Another aspect that would be valuable is to be able to download the most useful videos or those highlighted as favorites on your mobile phone. Photographs of Ana validating the DILSE application
