About the project
About EMBOA project
EMBOA is an acronym for project ”Affective loop in Socially Assistive Robotics as an intervention tool for children with autism”. The project is conducted by an international consortium and aims at the development of guidelines and practical evaluation of applying emotion recognition technologies in robot-supported intervention in children with autism.
It combines three domains: autism therapy, social robots and automatic emotion recognition.
EMBOA is a mixed research and didactic project under EU Erasmus Plus Strategic Partnership for Higher Education Programme. Years: 2019-2022.
Goal
The EMBOA project goal is to confirm the possibility of the application (feasibility study) of Affective Computing in Social Robotics, and in particular, we aim at the identification of the best practices and obstacles in using the combination of these technologies. What we hope to obtain is a novel approach for creating an affective loop in child-robot interaction that would enhance interventions regarding emotional intelligence building in children with autism.
Main tasks
- Identify state-of-the-art of emotion recognition applied in human-robot interaction in autism intervention, based on systematic literature review;
- Performing feasibility study confirming the possibility of the application;
- Identification of the best practices and obstacles in using the combination of the technologies;
- Development of guidelines and practical evaluation of applying emotion recognition technologies in robot-supported intervention in children with autism;
- The guidelines will be shared in English, Polish, German, Turkish and Macedonian.
Autism therapy
Children with autism spectrum disorder (ASD) suffer from multiple deficits, and limited social and emotional skills are among those, that influence their ability to involve in interaction and communication. There are promising results in the use of robots in supporting the social and emotional development of children with autism.
We do not know, why children with autism are eager to interact with human-like looking robots and not with humans. Regardless of the reason, social robots proved to be a way to get through the social obstacles of a child and make him/her involved in the interaction. Once the interaction happens, we have a unique opportunity to engage a child in gradually building and practicing social and emotional skills.
Robot-assisted therapy in autism has been a growing area of research in recent years. Humanoid robots, e.g., Robota, Nao, Kaspar, Milo have been used with children with autism to help mediate interactions with peers and adults. The ASD practitioners expressed the robot Kaspar to be of added value to ASD objectives in domains such as communication, interpersonal interaction, social relations, and emotional wellbeing. In the project we use Kaspar robot to study child-robot interaction. Kaspar robot was not used in conjunction with emotion recognition technologies before.
Emotion recognition
There are several works on facial expressions in children with autism. Multiple studies suggest that participants with ASD display facial expressions less frequently and shortly, and they are less likely to share facial expressions with others. However, participants with ASD do not express emotions less intensely, nor is their reaction time of expression onset slower. None of the studies reported were based on interaction with a social robot, however some studies reported emotional expressions in autism analyzed with automatic recognition software. The approach of the EMBOA project is to combine social robots with automatic emotion recognition in the therapy of children with autism.
As in all Erasmus Plus projects, the findings of the project will be widely disseminated in higher education, in research, among autism therapy specialists as well as to the general public in the variety of forms:
- 2 short-term joint staff training events;
- 1 intensive program for higher education learners;
- 6 multiplier events for autism therapy professionals and caregivers in all participating countries;
- openly available guidelines;
- scientific and technical papers,
- papers, posters and presentations to general public.

Intellectual outputs
IO 1
Systematic literature review and meta-analysis of emotion recognition in children with autism
The aim of the intellectual output was to investigate state-of-the-art in emotion recognition in children with autism.
The automatic emotion recognition domain brings new methods and technologies that might be used to enhance the therapy of children with autism. The study aimed at the exploration of methods and tools used to recognize emotions in children. It was performed as a literature review study using a systematic approach and PRISMA methodology for reporting quantitative and qualitative results. Diverse observation channels and modalities are used in the analyzed studies, including facial expressions, the prosody of speech, and physiological signals. Regarding representation models, the basic emotions are the most frequently recognized, especially happiness, fear, and sadness. Both single-channel and multichannel approaches are applied, with a preference for the first one. For multimodal recognition, early fusion was the most frequently applied. SVM and neural networks were the most popular for building classifiers. All channels are reported to be prone to some disturbance, and as a result, information on specific symptoms of emotions might be temporarily or permanently unavailable. The challenges of proper stimuli, labeling methods, and the creation of open datasets were also identified.

IO 2
Systematic literature review and meta-analysis of interventions regarding Robots and emotional skills in children with autism
The aim of the intellectual output was to explore the latest developments in social robots in intervention for children with autism.
Children with autism spectrum disorder (ASD) have deficits in the socio-communicative domain and frequently face severe difficulties in the recognition and expression of emotions. Existing literature suggested that children with ASD benefit from robot-based interventions. However, studies varied considerably in participant characteristics, applied robots, and trained skills. Nao and ZECA were the most frequently used robots; recognition of basic emotions and getting into interaction were the most frequently trained skills, while happiness, sadness, fear, and anger were the most frequently trained emotions. The studies reported a wide range of challenges with respect to robot-based intervention, ranging from limitations for certain ASD subgroups and security aspects of the robots to efforts regarding the automatic recognition of the children’s emotional state by the robotic systems. Finally, we summarised and discussed recommendations regarding the application of robot-based interventions for children with ASD.
