Our understanding of the effectiveness of motion-based touchless games for autistic children is limited, because of the small amount of empirical studies and the limits of our current knowledge on autism. This paper offers two contributions. First, we provide a survey and a discussion of the existing literature. Second, we describe a field study that extends the current body of empirical evidence of the potential benefits of touchless motion-based gaming for autistic children. Our research involved five autistic children and one therapist in the experimentation of a set of Kinect games at a therapeutic center for a period of two and a half months. Using standardized therapeutic tests, observations during game sessions, and video analysis of over 20 hours of children’s activities, we evaluated the learning benefits in relationship to attentional skills and explored several factors in the emotional and behavioral sphere. Our findings show improvements of the considered learning variables and help us to better understand how autistic children experience motion-based touchless play. Overall, our research sheds a light on the opportunities offered full body touchless games for therapy and education of these special users

Limited studies exist that explore motion-based touchless applications for children with ASD (Autism Spectrum Disorder) and investigate their design issues and the benefits they can bring to this target group. The paper reports a structured set of design guidelines that distill our experience gained from empirical studies and collaborations with therapeutic centers. These heuristics informed the design of three touchless games that were evaluated in a controlled study involving medium functioning ASD children at a therapeutic center. Our findings confirm the potential of motion-based touchless applications games in technology-enhanced interventions for this target group. BACKGROUNDThe Autistic Spectrum Disorder (ASD) is a general term for a group of complex disorders of brain development, characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors often accompanied by sensorimotor impairments. Autism, estimated to affect 1 of every 88 children, is marked by the presence of impairments along a triad of dimensions: social interaction, communication, and imagination. Children with autism show a great variance of symptoms, ranging from a delay or a total lack of spoken language to a severe impairment in the use of nonverbal behaviors that regulate social interaction, to a failure to develop peer relationships appropriate to age. ASD children also show imagination inability, manifested in the difficulty to generalize between environments, in a limited range of imaginative activities and in a difficulty in figuring out future events and abstract ideas. This reflects to a lack of spontaneous make-believe play or social imitative play and tendency to repetitive and stereotyped patterns of activity. Other behavioral symptoms include hyperactivity, short attention span, impulsivity, aggressiveness, self-injurious behavior, and temper tantrums. Studies conducted to consider the effectiveness of digital technologies for ASD children reveal that these tools are in general well received [16]. A digital environment provides stimuli that are more focused, predictable, and replicable than conventional tools. It also reduces the confusing, multi-sensory distractions of the real world that may induce anxiety and create barriers to social communication. In addition, digital tools can exploit the benefits of visually based interventions adopted in existing therapeutic practices such as video modeling [6]. Existing products and prototypes for autistic children exploit a variety of technologies and interaction modes, from desktop to multitouch mobile devices, tangibles and digitally augmented objects, robots [11], and more recently, touchless motion based environments, enabling users to interact using body movements without any physical contact with digital tools. The goal of our research is to design, develop and evaluate touchless motion based games that can be used for educational and therapeutic purposes in different contexts -school, therapeutic center, home...

Autism spectrum disorder (ASD) has become the fastest growing disability in the United States in 2013. The disorder is characterized by a triad of symptoms related to lack of social interaction, deficits in the acquisition and expression of language, and repetitive patterns of behavior often accompanied by sensorimotor impairments. In our research, we explore the use of motion based touchless games for ASD children and develop innovative tools that can be autonomously used by teachers/therapists in school classes or therapeutic activities. The paper describes the design and preliminary evaluation of "Pixel Balance", a motion based touchless game conceived to promote imitative capability, body schema awareness, and social skills in ASD children.

Our research explores the integration of motion-based touchless interaction with human-robots interaction to support game-based learning for children with intellectual disability. The paper discusses the design challenges of this novel approach and presents the design concepts of our initial prototypes. © 2014 Authors

Game activity is fundamental for children’s cognitive and social development. During recent years, technology development has led to changes in several areas, including the ludic one. However, while in the literature, there are plenty of studies that report the importance of technology-based games in rehabilitation program, little attention has been paid to their role as pure entertainment. In contrast, the market does not provide videogames that are engaging, accessible, and inclusive. In this context, a survey was distributed to families who have a child with neuromotor limitations to investigate how these children deal with play, in particular with videogames, and what the requirements are for accessible and inclusive videogames. FightTheStroke distributed the questionnaire to families with a child with neuromotor impairments in April 2020. Fifty-six families responded to the survey. The answers revealed that children generally manifest positive feelings when playing with videogames, especially with cooperative ones, even if they are not fully accessible. The survey also collected user needs and suggestions from families about the design of videogames for neuromotor-impaired children. Guidelines derived from the survey are reported for the development of entertaining, inclusive, and accessible videogames, playable by children with neuromotor disabilities.
