| Abstract | Autism is characterized by limitations in social interaction, speech, imitation and motor coordination. Recent studies suggest a link between imitation and Autism. In this paper, a robot is utilized to practice imitation learning in individuals with Autism. A system is proposed to gradually improve the imitation and social interaction of patients by adaptive training, which involves repetition of tasks close to the individual capacity limit and gradually increasing the capacity by improving the difficulty level. An ideal robot motion such as a hand wave performed by a trainer is recorded using a Kinect sensor and is replayed on the small humanoid robot Zeno. The motion is encoded on the robot using the Dynamic Movement Primitives (DMP) architecture, which is a set of non-linear differential equations used to generalize a motion by just changing the time, frequency and amplitude of the trajectory. The robot can adapt its motion to match that of the subject by analyzing the subject's movements by changing the DMP trajectory parameters accordingly. In the future, it is expected that this system will help subjects of different capabilities learn in a consistent manner by adaptively adjusting to their progress. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
