Transformations from a Symbol Language to a Sign Language by a Humanoid Robot for Blended Learning: Preliminary Application Results
Humans use both symbols and signs to communicate with one another. In particular, humans with learning difficulties emphasize signs. In recent years, there are mounting expectations for a seamless engagement of anthropomorphic robots in education. Our interest here is in blended learning applications involving anthropomorphic robots as assistants to human teachers toward improving education delivery to students with learning difficulties. In such context there is a need to transform symbols to signs. This paper presents preliminary application results regarding a transformation of symbols (i.e., spoken words) to signs in either the Greek or the Bulgarian sign languages by a NAO robot. We reveal advantages and disadvantages of the approach. We describe extensions toward bi-directional transformations between different physical languages and sign languages.
