People with Down syndrome have some physical and intellectual characteristics, that can cause motor and cognitive restrictions. The sociable robot must be able to interact with people in a reciprocal way, understanding and expressing attitudes, behaviors, feelings, and emotions. It is an observational, descriptive, and exploratory study containing field research. The Alfadown project an extension offered by PUC-Goiás made it possible to conduct the testing of the robot dancer with people that have SD. They were instructed to understand the proposed activity. First, the volunteer was positioned in front of the robot to begin the test execution. The same should mimic the movements and perform the commands issued by the robot. In this way, variables such as interest, visual contact, dissatisfaction, indifference, attention, and interaction with the robot were investigated and evaluated through the application of a questionnaire to assess the activity.
General Terms
In general, people with Down syndrome have cognitive limitations and motor difficulties that may compromise the individual's development throughout life. It is due to the genetic condition that imposes peculiarities, such as low muscle tone and difficulty in learning, making it difficult to understand and interact with and around the environment. However, the use of new technologies proves to be a promising route because it offers new stimuli that can be used as reinforcers in rehabilitation, training, and entertainment activities. An example is a provision and use of systems with tangible interfaces, whose interaction between the user and the machine happens through touch. It promotes proprioception, incites attention, interest, and concentration. This work describes the development and evaluation of a computational system with a tangible interface, called 3D Sandplay. This system offers a sandbox, which enables user interaction with the virtual world, amplified by Augmented Reality, for creating scenarios and understanding abstract concepts. 3D Sandplay was evaluated by a group of people with Down syndrome in three distinct activities and, in addition to achieving the events, the interest, attention, and resistance to complete the activities were evaluated. All research volunteers are students of the Alfadown project, an extension project maintained by PUC Goiás. Results have shown that 3D Sandplay is a tool that can contribute to the cognitive and motor development of children, adolescents, and adults with Down syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
