The authors of the development were scientists of the St. Petersburg Federal Research Center of the Russian Academy of Sciences. A neural network is trained on video. For this purpose, more than three thousand recordings with different gestures were made. The neural network was taught the language by students and teachers of the Interregional Center for Rehabilitation of Persons with Hearing Problems from Pavlovsk. The result of the training is already good - in 90% of cases the neural network understands what is being said to it. This development is needed to create technology to make life easier for people with hearing impairments. Thanks to this development, electronic assistants that understand sign language can be produced.
