Will artificial intelligence be a blessing or concern in assistive robots for play? / A inteligência artificial será uma bênção ou preocupação em robôs assistivos para brincar?

The recent advances and popularity of artificial intelligence (AI) offer exciting possibilities to improve technology but they also raise concerns. In this paper, we use our research to present the potential benefits of using AI in assistive technology for children with disabilities to access play, and examine potential ethical concerns surrounding data required by AI algorithms. Since play is a key factor in child well-being and cognitive development, secondary disabilities may arise as a consequence of motor impairments. Assistive robots for augmentative manipulation can be instrumental in providing children with physical disabilities play opportunities, but we need to take a principled and user-centered approach to technical innovations.

Os avanços recentes e popularidade da Inteligência Artificial (IA) oferecem possibilidades animadoras para melhorar a tecnologia, mas, também, trazem preocupação. Neste artigo, usamos nossa pesquisa para apresentar os benefícios potenciais do uso da IA em tecnologia assistiva para crianças com deficiências brincarem e examinar possíveis preocupações éticas em torno dos dados exigidos pelos algoritmos de IA. Uma vez que o brincar é um fator chave no bem-estar infantil e no desenvolvimento cognitivo, as incapacidades secundárias podem surgir como consequência de deficiências motoras. Robôs assistivos para manipulação aumentativa podem ser fundamentais para proporcionar às crianças com deficiência física oportunidades de brincar, mas precisamos adotar uma abordagem baseada em princípios e centrada no usuário para inovações técnicas.

Playfulness in Children with Limited Motor Abilities When Using a Robot.

AIMS: Children with limited gross motor and manual abilities have fewer opportunities to engage in free play. We investigated the effect of a robotic intervention on the playfulness of children with cerebral palsy (CP). METHODS: We used a partially nonconcurrent multiple baseline design with four children and their mothers. Children were classified in level IV or V on the Gross Motor Function and Manual Ability Classification Systems. The intervention was the availability of an adapted Lego robot during a 15-min free play session between the child and mother. There were two sessions per week for about 14 weeks. Playfulness was measured using the Test of Playfulness. RESULTS: Statistical comparisons using the 2 SD band and X-moving range chart methods revealed that all the children's levels of playfulness increased significantly while they played with the robot. Comparison of baseline and follow-up phase indicated that three children had retention of improved level of playfulness. CONCLUSION: Play with adapted Lego robots increased the level of playfulness in all four children during free play with their mothers. The findings have implications for providing children with limitations in motor abilities opportunities for free play with family and friends.

Using robots in "Hands-on" academic activities: a case study examining speech-generating device use and required skills.

PURPOSE: A 12-year-old girl, Emily, with complex communication needs and severe physical limitations, controlled a Lego robot from a speech-generating device (SGD) to do various "hands-on" academic activities. Emily's teacher and assistive technology (AT) team thought that controlling a robot would motivate Emily to "use her SGD more". METHOD: A descriptive case study was used because the integration of communication and manipulation technologies is not yet understood. Target activities and goals were chosen by Emily's teacher and AT team. Emily performed several manipulative math activities and engaged in an "acting" activity aimed at increasing her message length. The competency skills needed to control a robot from the SGD were examined, as well as stakeholder satisfaction with the robot system. RESULTS: Emily generated up to 0.4 communication events and 7 robot commands per minute in the activities. Her length of utterance was usually one-word long, but she generated two- and three-word utterances during some activities. Observations of Emily informed a framework to describe the competency skills needed to use SGDs to control robots. Emily and her teacher expressed satisfaction with robot use. CONCLUSION: Robot use could motivate students to build SGD operational skills and learn educational concepts. Implications for Rehabilitation Controlling a robot from a speech-generating device (SGD) could increase students' motivation, engagement and understanding in learning educational concepts, because of the hands-on enactive approach. The robot and SGD system was acceptable to the participant and teacher and elicited positive comments from classmates. Thus, it may provide a way for children with disabilities to link with the curriculum and with other students in the classroom. Controlling a robot via SGD presents opportunities to improve augmentative and alternative communication operational, linguistic, social and strategic skills. Careful choice of activities will ensure that the activity requirements focus on the desired target skill, e.g. drawing or playing board games could be helpful to build operational skills and acting out stories could be helpful for building linguistic skills.

Using virtual robot-mediated play activities to assess cognitive skills.

PURPOSE: To evaluate the feasibility of using virtual robot-mediated play activities to assess cognitive skills. METHOD: Children with and without disabilities utilized both a physical robot and a matching virtual robot to perform the same play activities. The activities were designed such that successfully performing them is an indication of understanding of the underlying cognitive skills. RESULTS: Participants' performance with both robots was similar when evaluated by the success rates in each of the activities. Session video analysis encompassing participants' behavioral, interaction and communication aspects revealed differences in sustained attention, visuospatial and temporal perception, and self-regulation, favoring the virtual robot. CONCLUSIONS: The study shows that virtual robots are a viable alternative to the use of physical robots for assessing children's cognitive skills, with the potential of overcoming limitations of physical robots such as cost, reliability and the need for on-site technical support. IMPLICATIONS FOR REHABILITATION: Virtual robots can provide a vehicle for children to demonstrate cognitive understanding. Virtual and physical robots can be used as augmentative manipulation tools allowing children with disabilities to actively participate in play, educational and therapeutic activities. Virtual robots have the potential of overcoming limitations of physical robots such as cost, reliability and the need for on-site technical support.

Access to hands-on mathematics measurement activities using robots controlled via speech generating devices: three case studies.

PURPOSE: To examine how using a robot controlled via a speech generating device (SGD) influences the ways students with physical and communication limitations can demonstrate their knowledge in math measurement activities. METHOD: Three children with severe physical disabilities and complex communication needs used the robot and SGD system to perform four math measurement lessons in comparing, sorting and ordering objects. The performance of the participants was measured and the process of using the system was described in terms of manipulation and communication events. Stakeholder opinions were solicited regarding robot use. RESULTS: Robot use revealed some gaps in the procedural knowledge of the participants. Access to both the robot and SGD was shown to provide several benefits. Stakeholders thought the intervention was important and feasible for a classroom environment. CONCLUSIONS: The participants were able to participate actively in the hands-on and communicative measurement activities and thus meet the demands of current math instruction methods. IMPLICATIONS FOR REHABILITATION: Current mathematics pedagogy encourages doing hands-on activities while communicating about concepts. Adapted Lego robots enabled children with severe physical disabilities to perform hands-on length measurement activities. Controlling the robots from speech generating devices (SGD) enabled the children, who also had complex communication needs, to reflect and report on results during the activities. By using the robots combined with SGDs, children both exhibited their knowledge of and experienced the concepts of mathematical measurements.

Mothers' perceptions of their children's use of powered mobility.

Physical therapists and occupational therapists frequently assist parents with the exploration and use of powered wheelchairs for their children with physical disabilities. The purpose of this study was to explore parents' experiences and perceptions of their children's experiences with the receipt and use of powered mobility. Qualitative methods were used to gain insight into the experiences of five mothers of children with physical disabilities who use powered wheelchairs. Information was collected during individual interviews with the mothers. Data analyses revealed five higher-level themes identified across the participants. Results of this study suggest that mothers initially perceive powered mobility as a "last resort" mobility option. The perceived effects of their children's use of powered mobility were significant and included increased personal control, independence, and opportunities to participate in age appropriate, meaningful activities. The mothers perceived that increased independence positively affected others' attitudes toward their children and allowed their children to develop more "legitimate" relationships with their peers.

Evaluation of powered mobility use in home and community environments.

The purpose of this study was to evaluate the use of powered mobility by young individuals with physical disabilities. The four study objectives were to: (a) describe the characteristics of children and adolescents who received powered wheelchairs at eighteen years of age or younger, (b) evaluate the longitudinal use or disuse of powered mobility by these participants, (c) describe the extent and locations of powered mobility use, and (d) explore environmental (i.e., physical, social and attitudinal) barriers and facilitators to successful powered mobility use with the participants and their families. Sixty-six families shared information during a structured telephone interview. The results of this study confirm that younger children are now receiving powered wheelchairs. The results also suggest that powered mobility is reserved for children with the most severe disabilities. Physical and occupational therapists can work collaboratively with more families to explore powered mobility as one of an array of early movement options.
