Exploring Collaborative Interactions Between Robots and Blind People VIDEO

Two blind people doing a tagram puzzle with the help of a robot. One the robot is helping the user with its arms (Condition CAR); in the other the robot is still just providing audio instructions (Condition VOAR).

Our goal is to disseminate an exploratory investigation that examined how physical presence and collaboration can be important factors in the development of assistive robots that can go beyond information-giving technologies. In particular, this video exhibits the setting and procedures of a user study that explored different types of collaborative interactions between robots and blind people.
