Lärares erfarenheter av rörelser i svenskundervisning : En kvalitativ studie / Teachers experience of movement in teaching SwedishKarlsson, kevin January 2022 (has links)
The purpose of this study is to increase the knowledge of professional teachers’ experiences of learning with the help of body movement in the subject of Swedish. Qualitative interviews have been used as an instrument for research. The results derive from the answers of five respondents who are all professional teachers of children between the grades f-6 (ages 6 to12). The answers contribute to providing an understanding of teachers’ views on the link between body movements and learning in the subject of Swedish. The essay shows that the teachers have experiences of body movements in the subject of Swedish and what type of exercises they prefer in the subject of Swedish. The results also show that teachers prefer exercises that build on modeling and that movements are thought of as a means of increased concentration and motivation rather than as part of a didactic strategy.

Spot the Pain: Exploring the Application of Skeleton Pose Estimation for Automated Pain AssessmentHjelm Gardner, Angelica January 2022 (has links)
Automated pain assessment is emerging as an essential part of pain management in areas such as healthcare, rehabilitation, sports and fitness. These automated systems are based on machine learning applications and can provide reliable, objective and cost-effective benefits. To enable an automated approach, at least one channel of sensory input, known as modality, must be available to the system. So far, most studies of automated pain assessment have focused on facial expressions or physiological signals, and although body gestures are considered to be indicators of pain, not much attention has been paid to this modality. Using skeleton pose estimation, we can model body gestures and investigate how body movement information affects pain assessment performance in different approaches. In this study, we explored approaches to pain assessment using skeleton pose estimation for three objectives: pain recognition, pain intensity estimation, and pain area classification. Because pain is a complex experience and is often expressed across multiple modalities, we analysed both unimodal approaches using only body data and bimodal approaches using skeleton pose estimation with facial expressions and head pose. In our experiments, we trained models based on two deep learning architectures: a hybrid CNN-BiLSTM and a recurrent CNN (RCNN), on a real-world dataset consisting of video recordings of people performing an overhead deep squat exercise. We also investigated bimodal fusion of body and face modalities in three different strategies: early fusion, late fusion and ensemble learning. Although our results are still preliminary, they show promising indications and possible future improvements. The best performance was obtained with ensemble for pain recognition (AUC 0.71), unimodal body CNN-BiLSTM for pain intensity estimation (AUC 0.75) and late fusion of body and face modalities using RCNN for pain area classification (AUC 0.75). Our experimental results demonstrate the feasibility of using skeleton pose estimation to represent body modality, the importance of incorporating body movements into automated pain assessment, and the exploration of the previously understudied assessment objective of localising pain areas in the body.
