Educational Resources as Digital Products

Abstract. In the paper educational resources are treated as regular digital products. The problem of the production, distribution and sale is addressed, especially concentrating on the production effort, cost and price. An original method of estimating development effort of e-learning resources is described and experimental results are presented. The paper presents also two extensions of the existing structure and implementation of learning objects. The structure of a learning object, although flexible, focuses on reuse, which is insufficient for independent learning. Therefore the first extension is the concept of a teaching object that contains all parts of the educational process, from knowledge presentation, through examples and exercises to final examinations. A teaching object is proposed as an independent subject of sale. Addition of data access methods to learning objects is the second proposed extension that creates a learning component. A model of learning object distribution based on Web services and learning components is proposed

Automatic Emotion Recognition in Children with Autism: A Systematic Literature Review

© 2022 by the authors. Licensee MDPI, Basel, Switzerland. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (https://creativecommons.org/licenses/by/4.0/).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.Peer reviewedFinal Published versio

Technology adoption review for ageing well: analysis of technical solutions

While several technological solutions are available for older adults to improve their wellbeing and quality of life, little is known about the gaps between the needs, provided solutions, and their adoption from a more pragmatic perspective. This paper reports on reviewing existing technological solutions for older adults, which span the work life, life in the community, and wellbeing at home. We analyzed 50 different solutions to uncover both negative and positive features of these solutions from the perspective of the impact of technology adoption on the quality of life of older adults. Our approach harnesses holistic reasoning to determine the most suitable technologies available today and provides suggestions for improvement toward designing and implementing better solutions

Emotion Monitoring – Verification of Physiological Characteristics Measurement Procedures

This paper concerns measurement procedures on an emotion monitoring stand designed for tracking human emotions in the Human-Computer Interaction with physiological characteristics. The paper addresses the key problem of physiological measurements being disturbed by a motion typical for human-computer interaction such as keyboard typing or mouse movements. An original experiment is described, that aimed at practical evaluation of measurement procedures performed at the emotion monitoring stand constructed at GUT. Different locations of sensors were considered and evaluated for suitability and measurement precision in the Human- Computer Interaction monitoring. Alternative locations (ear lobes and forearms) for skin conductance, blood volume pulse and temperature sensors were proposed and verified. Alternative locations proved correlation with traditional locations as well as lower sensitiveness to movements like typing or mouse moving, therefore they can make a better solution for monitoring the Human-Computer Interaction

Towards New Mappings between Emotion Representation Models

There are several models for representing emotions in affect-aware applications, and available emotion recognition solutions provide results using diverse emotion models. As multimodal fusion is beneficial in terms of both accuracy and reliability of emotion recognition, one of the challenges is mapping between the models of affect representation. This paper addresses this issue by: proposing a procedure to elaborate new mappings, recommending a set of metrics for evaluation of the mapping accuracy, and delivering new mapping matrices for estimating the dimensions of a Pleasure-Arousal-Dominance model from Ekman’s six basic emotions. The results are based on an analysis using three datasets that were constructed based on affect-annotated lexicons. The new mappings were obtained with linear regression learning methods. The proposed mappings showed better results on the datasets in comparison with the state-of-the-art matrix. The procedure, as well as the proposed metrics, might be used, not only in evaluation of the mappings between representation models, but also in comparison of emotion recognition and annotation results. Moreover, the datasets are published along with the paper and new mappings might be created and evaluated using the proposed methods. The study results might be interesting for both researchers and developers, who aim to extend their software solutions with affect recognition techniques

What is the phenomenon of Jára Cimrman Theatre ?

Przedmiotem pracy jest czeski Teatr im. Jary Cimrmana w Pradze. Praca ma być próbą przybliżenia jego fenomenu. Jara Cimrman to dla Czechów postać kultowa, a teatr jego imienia od ponad czterdziestu lat cieszy się niezmiennym powodzeniem. W mojej pracy spróbuje przybliżyć nieco postać Jary - nieistniejącego geniusza, a także postaci jego twórców - Zdenka Sveraka i Ladislava Smoljaka.Przede wszystkim jednak zajmować mnie będzie sam teatr oraz prezentowany w nim rodzaj humoru. W mojej pracy opisuje okoliczności jego powstania, osoby, które wpływały i wpływają na jego dzisiejszy kształt. Zajmuje się również zjawiskiem mistyfikacji i jej znaczeniem w czeskiej kulturze. Przede wszystkim jednak praca jest próbą uchwycenia specyficznego humoru prezentowanego w teatrze przez grupę ludzi mówiących o sobie Cimrmani. W poniższej pracy zajmuje się opisem ich działalności i sylwetek a także analizą ich scenicznych działań, które balansują gdzieś na granicy pomiędzy teatrem a kabaretem.In this thesis I am focusing on Czech Theatre. Named after Jara Cimrman .Work is an attempt to familiarize it’s phenomenon. Jara Cimrman is a cult figure for the Czechs, and his theatre for over forty years is invariably popular. In my work I attempt to approximate a figure of Jara Cimrman and his creators – Zdenek Sverak and Ladislav Smoljak. But mainly I would write about Jara Cimrman Theatre and the specific humor that is presented on its boards. In my work I describe the circumstances of its creation, people who has influenced and are still affecting its present shape. I am also writing about phenomenon of mystification and its importance in the Czech culture Above all, the work is an attempt to capture specific humor presented in the theater by a group of people talking about themselves Cimrman. In this work I am describing their profiles and activities, but most of all I am analyzing their actions on stage, which balances somewhere between theatre and cabaret
