A Preliminary Study on Effectiveness of a Standardized Multi-Robot Therapy for Improvement in Collaborative Multi-Human Interaction of Children with ASD

This research article presents a preliminary longitudinal study to check the improvement in multi-human communication of children with Autism Spectrum Disorder (ASD) using a standardized multirobot therapy. The research is based on a 3 step framework: 1) Human-Human Interaction, Stage-1 (HHIS1), 2) Human-Robot Interaction, Stage-2 (HRI-S2), and 3) Human-Human Interaction, Stage-3 (HHI-S3). All three stages of the therapy consist of two command sets: 1) Controls commands and 2) Evaluation commands (auditory commands, visual commands, and combination of both). The concept of multiple robots is introduced to help multi-human communication and discourage isolation in ASD children. The joint attention of an ASD child is improved by the robotic therapy in stage 2 considering it as a key parameter for a multi-human communication scenario. The improvement in joint attention results in better command following in a triad multi-human communication scenario in stage 3 as compared to stage 1. The proposed intervention has been tested on 8 ASD subjects with 10 sessions over a period of two and a half months (10 weeks). Each session of human-human interaction (stage 1 and 3) consisted of 14 cues whereas 18 cues were presented by each robot for human-robot interaction (stage 2). The results indicate an overall 86improvement in the social communication skills of ASD children in case of a multi-human scenario. Validation of results and effectiveness of the therapy has been further accomplished through the use of the Childhood Autism Rating Scale (CARS) score

Applications of Robotics for Autism Spectrum Disorder: a Scoping Review

Robotic therapies are receiving growing interest in the autism field, especially for the improvement of social skills of children, enhancing traditional human interventions. In this work, we conduct a scoping review of the literature in robotics for autism, providing the largest review on this field from the last five years. Our work underlines the need to better characterize participants and to increase the sample size. It is also important to develop homogeneous training protocols to analyse and compare the results. Nevertheless, 7 out of the 10 Randomized control trials reported a significant impact of robotic therapy. Overall, robot autonomy, adaptability and personalization as well as more standardized outcome measures were pointed as the most critical issues to address in future research

An Experimental Trial: Multi-Robot Therapy for Categorization of Autism Level Using Hidden Markov Model

Several robot-mediated therapies have been implemented for diagnosis and improvement of communication skills in children with Autism Spectrum Disorder. The proposed research uses an existing model i.e., Multi-robot-mediated Intervention System (MRIS) in combination with Hidden Markov Model (HMM) to develop an infrastructure for categorizing the severity of autism in children. The observable states are joint attention type (low, delayed, and immediate) and imitation type (partial, moderate, and full) whereas the non-observable states are (level of autism i.e., (minimal, and mild). The research has been conducted on 12 subjects in which 8 children were in the training session with 72 experiments over 9 weeks, and the remaining 4 subjects were in the prediction test with 25 experiments for 6 weeks. The predicted category was compared with the actual category of autism assessed by the therapist using Childhood Autism Rating Scale. The accuracy of the proposed model is 76%. Further, a statistically significantly moderate Kappa measure of agreement between Childhood Autism Rating Scale and our proposed model has been performed in which n = 25, k = 0.52, and p = 0.009. This research contributes towards the usefulness of Hidden Markov Model integrated with joint attention and imitation modules for categorizing the level of autism using multi-robot therapies

Occupational Therapy Interventions Using New Technologies in Children and Adolescents with Autism Spectrum Disorder: A Scoping Review

New technologies (NT) are increasingly used in Occupational Therapy (OT) interventions in people with Autism Spectrum Disorder (ASD). We conducted a scoping review to describe OT interventions investigated in scientific literature which use NT in children and adolescents with ASD. Two authors independently searched the scientific databases PubMed, EMBASE, Scopus and Web of Science, carried out a peer-review screening of articles and extracted data. Twenty studies met the inclusion criteria. OT interventions lasted between 1 week and 12 months, consisted of between 1 session per day and 5 sessions per week, were carried out exclusively by an occupational therapist, and the most used NT was the computer (n = 12). The duration of the interventions and assessment measures used varied greatly between studies

Social Robots to enhance therapy and interaction for children: From the design to the implementation "in the wild"

En les últimes dues dècades els robots socials s'han convertit en un camp emergent en el qual encara hi ha molt per fer. Aquest camp requereix coneixements en mecànica, control, intel·ligència artificial, sistemes, etc., però també en psicologia, disseny, ètica, etc. El nostre grup de recerca de perfil interdisciplinari ha estat treballant en el disseny de robots socials en diferents aplicacions per a nens amb necessitats especials. L'objectiu d'aquesta tesi és investigar diferents escenaris en teràpia o educació on els robots socials podrien ser una eina útil per als nens. Es van realitzar 4 estudis amb diferents propòsits: (1) dissenyar activitats amb robòtica de LEGO per avaluar el comportament social dels nens amb trastorn de l'espectre autista (TEA) (entre companys i amb adults) i analitzar la seva efectivitat, (2) dissenyar un robot social per recuperar les funcionalitats més afectades a causa de traumatismes cranioencefàlics (TCE) en nens i veure l'eficàcia del tractament, (3) proporcionar un robot mascota per alleujar els sentiments d'ansietat, solitud i estrès en nens hospitalitzats, i (4) comprovar com un robot amb comportament social i amb una personalització versus robots sense aquestes característiques mostra diferències en termes d'interacció amb nens i, per tant, pot ajudar en l'efectivitat de diferents tractaments com hem esmentat anteriorment. Els resultats van revelar diferents resultats depenent de l'aplicació: (1) efectivitat amb la plataforma robòtica social que vam dissenyar en el tractament neuropsicològic per a aquells nens afectats per TCE, (2) eficàcia amb les activitats de robòtica de LEGO dissenyades per un grup de terapeutes en termes de millora d'habilitats socials (3) un efecte positiu entre els mediadors i facilitadors de la interacció i les relacions entre els diferents agents involucrats en el procés de la cura: pacients hospitalitzats, familiars, voluntaris i personal clínic, i (4) una interacció diferent, en termes de temps, entre els dos grups durant període de dues setmanes.En las últimas dos décadas los robots sociales se han convertido en un campo emergente en el que todavía hay mucho por hacer. Este campo requiere conocimientos en mecánica, control, inteligencia artificial, sistemas, etc., pero también en psicología, diseño, ética, etc. Nuestro grupo de investigación de perfil interdisciplinar ha estado trabajando en el diseño de robots sociales en diferentes aplicaciones para niños con necesidades especiales. El objetivo de esta tesis es investigar diferentes escenarios en terapia o educación donde los robots sociales podrían ser una herramienta útil para los niños.

Los resultados revelaron diferentes resultados dependiendo de la aplicación: (1) efectividad con la plataforma robótica social que diseñamos en el tratamiento neuropsicológico para aquellos niños afectadas por TCE, (2) eficacia con las actividades de robótica de LEGO diseñadas por un grupo de terapeutas en términos de mejora de habilidades sociales (3) un efecto positivo entre los mediadores y facilitadores de la interacción y las relaciones entre los diferentes agentes involucrados en el proceso del cuidado: pacientes hospitalizados, familiares, voluntarios y personal clínico, y (4) una interacción diferente, en términos de tiempo, entre ambos grupos en el promedio de un período de dos semanas.Over the past two decades social robots have become an emerging field where there are many things still to work on. This field not only requires knowledge in mechanics, control, artificial intelligence, systems, etc., but also in psychology, design, ethics, etc. Our multidisciplinary research group has been working on designing social robotic platforms in different applications for children with special needs. The aim of this thesis is to investigate different scenarios in therapy or education where social robots could be a useful tool for children. We ran 4 studies with different purposes: (1) to design activities with LEGO robotics to assess children with autism spectrum disorder (ASD) social behaviour (between peers and with adults) and to analyze the effectiveness, (2) to design a social robotic platform to recover the functionalities most affected by traumatic brain injuries (TBI) in children and see the effectiveness of the treatment, (3) to provide a pet robot to alleviate feelings of anxiety, loneliness and stress of long-term children inpatient and their bystanders, and (4) to verify how a robot with social behaviour and personalization verses those robots without, shows differences in terms of interaction with children and thus, helps the effectiveness of different treatments as we mention above. The results revealed different outcomes depending on the application: (1) effectiveness with the social robotic platform that we designed in neuropsychological treatment in those areas affected by TBI, (2) effectiveness with the LEGO robotics activities designed by a group of therapists in terms of improvement of the social skills and engagement, (3) a positive effect within mediators and facilitators of interaction and relationships between the different agents involved in the caring process: in-patients, relatives, volunteers and clinical staff (4) slight evidence towards a different interaction, in terms of time, between both groups in the average of a two-week period

Patient centric intervention for children with high functioning autism spectrum disorder. Can ICT solutions improve the state of the art ?

In my PhD research we developed an integrated technological platform for the acquisition of neurophysiologic signals in a semi-naturalistic setting where children are free to move around, play with different objects and interact with the examiner. The interaction with the examiner rather than with a screen is another very important feature of the present research, and allows recreating a more real situation with social interactions and cues. In this paradigm, we can assume that the signals acquired from the brain and the autonomic system, are much more similar to what is generated while the child interacts in common life situations. This setting, with a relatively simple technical implementation, can be considered as one step towards a more behaviorally driven analysis of neurophysiologic activity. Within the context of a pilot open trial, we showed the feasibility of the technological platform applied to the classical intervention solutions for the autism. We found that (1) the platform was useful during both children-therapist interaction at hospital as well as children-parents interaction at home, (2) tailored intervention was compatible with at home use and non-professional therapist/parents. Going back to the title of my thesis: 'Can ICT solution improve the state-of-the-art ?' the answer could be: 'Yes it can be an useful support for a skilled professional in the field of autis
