Sign Language Learning Systems

Fig. 3: Sign Language Tutoring Systems
Figure 3 lists a number of tutoring systems from 2005 until 2016.

  • Three categories are distinguished among identified systems. Tutoring systems are roughly categorised as the categories are not mutually exclusive.
    1. Items in the first category teach sign language to its users without any explicit knowledge evaluation. 
    2. Teach & test category contains most of the elements and lists systems that perform both teaching and testing of user's knowledge. 
    3. Third category distinguished is more specific than the first two as it names systems that foster interaction and communication among their users (e.g. deaf children or non-deaf family members and deaf children).
  • Colour-coding in the figure groups systems based on their target groups: non-deaf parents of deaf children, deaf children, both non-deaf parents of deaf children and deaf children, any children, and any users.
  • Two categories include items that are highlighted with line under and both bold and inclined text. These items correspond to the names of the systems that feature robotic devices in them to perform teaching and/or testing of user's knowledge.
