Sometime, use of augmented reality can be very concrete. In this study from the Kangwon National University (Korea), authors show that using AR training with smart toothbrush helps people with intellectual disabilities to greatly improve oral hygiene.
As a result, it was shown that tooth-brushing training based on AR using a smart toothbrush was more effective than the training using visual materials in improving oral hygiene care among people with intellectual disabilities. Tooth-brushing training based on AR using a smart toothbrush can be used as an effective tool to solve the problems of the training using visual material in the residential care facility for people with intellectual disabilities.
