A proposal for visually handicapped students to use electrical control laboratory

In this paper a technical solution is presented for blind or visually impaired students to acquire abilities of experimental work in laboratory conditions enabling them to participate in the experiments jointly with the healthy students. For this purpose a special apparatus has been designed, which possesses deciding and declaring properties to aid the visually impaired persons in the laboratory environment. An approach based on artificial neural network was implemented. Motor sounds generated during experiments were used for training the ANN model. The results demonstrate that the designed ANN model produces highly reliable estimates used in the operation of the apparatus.
