Mirror illusion has been widely and successfully used in therapeutic settings to treat chronic pain patients but the mechanisms involved in the mirror illusion are yet not well understood. The aims of this study are: (a) to investigate a relationship between body ownership and the visual illusion of an increased/decreased hand size; (b) to understand whether tactile acuity and inner representations of the hands can be modulated by a mirror illusion using an Augmented Reality setting. 33 healthy right- handed volunteers participated in the study. Results indicate, that the degree of ownership to the enlarged hand and to the hand in the control condition can modulate inner representation of the hands and tactile acuity. These findings could have an important impact on how to utilise augmented reality and mirror illusion in therapy.
