Hand gestures of visually impaired and sighted interactants

This study investigated the types of gestures used, the frequency of the gestures, and the total time engaged in gestural communication by 11 visually impaired-sighted dyads; 12 sighted-sighted dyads; and 8 visually impaired-visually impaired dyads. Regardless of the type of dyad, the persons who were visually impaired used more adaptors and used gestures, emblems, and illustrators less often than did those who were sighted.
