The automatic emotion recognition domain brings new methods and technologies that might be used to enhance therapy of children with autism. The paper aims at the exploration of methods and tools used to recognize emotions in children. It presents a literature review study that was performed 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, 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. Qualitative analysis revealed important clues on participant group construction and the most common combinations of modalities and methods. All channels are reported to be prone to some disturbance, and as a result, information on a specific symptoms of emotions might be temporarily or permanently unavailable. The challenges of proper stimuli, labelling methods, and the creation of open datasets were also identified. [ABSTRACT FROM AUTHOR]

This article describes an exploratory study involving the design of an after-school robotics class for groups of children at the higher-functioning end of the autistic spectrum. The aim of the study was to foster collaboration among the children in the context of a class where they programmed Lego robots under the guidance of an experimenter. The class took place once a week over several months and used many different measures to assess the children’s collaborative behaviours. Detailed analysis of behavioural data is presented, and despite the small sample size, our findings suggest that the number of potentially collaborative behaviours the children displayed during a class is more strongly related to the amount of enjoyment the children derived from the classes than to the number of classes in which the children participated. Parallel-run, free-form drawing sessions conducted before certain classes gave some indication that these behavioural changes partly generalized to a different context. Additionally, many of the children in the class either found their experiences in class to be helpful in other social interactions or expected them to be. [ABSTRACT FROM AUTHOR]
