Human Robot Interaction System for Behavioral Improvement of Autistic Children

摘要

An estimated one-third of people with autism are nonverbal. Many Research has been done in this field and confirms that people with autism experience a lack of communication skills, anxiety, dealing with change, bullying, etc. To assist autistic children and to improve their behavior, we have developed an artificial intelligence robot that can react to their movement via an ultrasonic sensor and can talk to them via voice commands. Using this robot, children with ASD can develop both their behavior and communication skill. The robot works in two methods. The first one is the ultrasonic sensor, implemented with an AI algorithm that can detect a person within seventy centimeters. This ultrasonic sensor sends the data to the controller and the controller receives the signal and sends an activation signal to the robot. Finally, the robot moves his head to the direction of the person is located or to the moving direction. The second method is voice commands. The robot can perform each physical action it is given via voice commands like a salute, handshaking, body movement, and answering questions achieving 97.75% average accuracy with the response time of 328.75ms. This accuracy is achieved by testing the system for 10 iterations. As autistic children hesitate to communicate freely with normal people, this human-robot interaction will improve their behavior and communication skills as well. This humanoid robot will improve the quality of living of the autistic or disabled people. This humanoid robot can be used in any public sector like school, colleges, an autism center, and industry.
