Companion-Technology. Due to their flexibility and the variety of interaction options, such multi-screen scenarios are hardly intuitive for the user.

Especially, intentional and emotional characteristics are essential to improve not only the relationship in a human-human interaction, but also to provide benefits to increase the understanding of the transmitted information. For technical systems it is favourable to detect and interpret these additional characteristics and to transfer appropriate knowledge to human-machine interactions. In particular, this enables an automatic recognition of emotions. In this paper, we focus on speech as the transmitting modality. Beyond the detection of the location and nature of emotional instances, automatic interpretation asks "if", "how", and "when" emotions change in an interaction. In the EmoGest corpus, providing human-human interactions with emotionally induced subjects, we analyse the subject's emotional evolution. For this, we investigate the utterances spoken at the beginning and at the end of particular sessions. Automatic emotion recognition from speech shows that in intra- and inter-individual evaluations, significant differences (at least p<0.05) in the emotional state train of the subjects can be detected. Intra-individual experiments indicate a trend towards less affective states in subsequent interactions if no further inducement is given.

Therefore, we systematically studied the neuronal correlates of voluntary facial movements using the Facial Action Coding System (FACS, Ekman et al., 2002). The facial movements performed in the MRI scanner were defined as Action Units (AUs) and were controlled by a certified FACS coder. The main goal of the study was to investigate the detailed somatotopy of the facial primary motor area (facial M1). Eighteen participants were asked to produce the following four facial movements in the fMRI scanner: AU1+2 (brow raiser), AU4 (brow lowerer), AU12 (lip corner puller) and AU24 (lip presser), each in alternation with a resting phase. Our facial movement task induced generally high activation in brain motor areas (e.g., M1, premotor cortex, supplementary motor area, putamen), as well as in the thalamus, insula, and visual cortex. BOLD activations revealed overlapping representations for the four facial movements. However, within the activated facial M1 areas, we could find distinct peak activities in the left and right hemisphere supporting a rough somatotopic upper to lower face organization within the right facial M1 area, and a somatotopic organization within the right M1 upper face part. In both hemispheres, the order was an inverse somatotopy within the lower face representations. In contrast to the right hemisphere, in the left hemisphere the representation of AU4 was more lateral and anterior compared to the rest of the facial movements.

Previously, Probability Hypothesis Density (PHD) and Cardinalised PHD (CPHD) filters based on GGIW mixtures have been proposed to solve the extended target tracking problem. Although these are computationally cheaper, they involve significant approximations, as well as lacking the ability to maintain target tracks over time.

Combination of information generally goes along with the level of abstractness, time granularity and robustness, such that large \{CTS\} architectures must perform fusion gradually on different levels — starting from sensor-based recognitions to highly abstract logical inferences. In our \{CTS\} application we sectioned information fusion approaches into three categories: perception-level fusion, knowledge-based fusion and application-level fusion.

This format accumulates the activity of the pixels over a short time, i.e. several μs. The optic flow is estimated by a new neural model mechanism which is inspired by the motion pathway of the visual system and is consistent with the vision sensor functionality, where new temporal filters are proposed. Since the DVS already generates temporal derivatives of the input signal, we thus suggest a smoothing temporal filter instead of biphasic temporal filters introduced by (Adelson and Bergen, 1985). Our model extracts motion information via a spatiotemporal energy mechanism which is oriented in the space-time domain and tuned in spatial frequency. To achieve balanced activities of individual cells against the neighborhood activities, a normalization process is carried out. We tested our model using different kinds of stimuli that were moved via translatory and rotatory motions. The results highlight an accurate flow estimation compared with synthetic ground truth. In order to show the robustness of our model, we examined the model by probing it with synthetically generated ground truth stimuli and realistic complex motions, e.g. biological motions and a bouncing ball, with satisfactory results.} } @INPROCEEDINGS {Kachele2015, author = {K{\"a}chele, Markus and Rukavina, Stefanie and Palm, G{\"u}nther and Schwenker, Friedhelm and Schels, Martin}, title = {Paradigms for the Construction and Annotation of Emotional Corpora for Real-World Human-Computer-Interaction}, booktitle = {Proceedings of the International Conference on Pattern Recognition Applications and Methods (ICPRAM)}, year = {2015}, pages = {367--373}, publisher = {SciTePress}, doi = {10.5220/0005282703670373}, isbn = {978-989-758-076-5}, owner = {mkaechele}, timestamp = {2014.11.17}, abstract = {A major building block for the construction of reliable statistical classifiers in the context of affective human-computer interaction is the collection of training samples that appropriately reflect the complex nature of the desired patterns. This is especially in this application a non-trivial issue as, even though it is easily agreeable that emotional patterns should be incorporated in future computer operating, it is by far not clear how it should be realized. There are still open questions such as which types of emotional patterns to consider together with their degree of helpfulness for computer interactions and the more fundamental question on what emotions do actually occur in this context. In this paper we start by reviewing existing corpora and the respective techniques for the generation of emotional contents and further try to motivate and establish approaches that enable to gather, identify and categorize patterns of human-computer interaction.} } @INCOLLECTION {Kachele2014c, author = {K{\"a}chele, Markus and Schels, Martin and Meudt, Sascha and Kessler, Viktor and Glodek, Michael and Thiam, Patrick and Tschechne, Stephan and Palm, G{\"u}nther and Schwenker, Friedhelm}, title = {On Annotation and Evaluation of Multi-modal Corpora in Affective Human-Computer Interaction}, booktitle = {Multimodal Analyses enabling Artificial Agents in Human-Machine Interaction}, publisher = {Springer International Publishing}, year = {2015}, isbn = {978-3-319-15556-2}, series = {Lecture Notes in Computer Science}, editor = {B{\"o}ck, Ronald and Bonin, Francesca and Campbell, Nick and Poppe, Ronald}, doi = {10.1007/978-3-319-15557-9_4}, url = {http://dx.doi.org/10.1007/978-3-319-15557-9_4}, keywords = {Affective computing; Annotation; Machine learning; Human computer interaction; Multimodal corpora; Fuzzy memberships}, pages = {35--44}, language = {English}, abstract = {In this paper, we discuss the topic of affective human-computer interaction from a data driven viewpoint.

Based on planning technology, we are able to provide advanced user assistance for operating technical devices. We present a system that assists a human user in setting up a complex home theater consisting of several HiFi devices. For a human user, the task is rather challenging due to a large number of different ports of the devices and the variety of available cables. The system supports the user by giving detailed instructions how to assemble the theater. Its performance is based on advanced user-centered planning capabilities including the generation, repair, and explanation of plans.} } @ARTICLE {Wolff2015, author = {Wolff, Susann and Brechmann, Andr{\'e}}, title = {Carrot and stick 2.0: The benefits of natural and motivational prosody in computer-assisted learning}, journal = {Computers in Human Behavior}, year = {2015}, volume = {43}, pages = {76--84}, url = {http://www.sciencedirect.com/science/article/pii/S074756321400538X}, document_type = {Article}, abstract = {For acquiring new skills or knowledge, contemporary learners frequently rely on the help of educational technologies supplementing human teachers as a learning aid. In the interaction with such systems, speech-based communication between the human user and the technical system has increasingly gained importance. Since spoken computer output can take on a variety of forms depending on the method of speech generation and the employment of prosodic modulations, the effects of such auditory variations on the user's learning achievement require systematic investigation. The experiment reported here examined the specific effects of speech generation method and prosody of spoken system feedback in a computer-supported learning environment, and may serve as validational tool for future investigations of spoken computer feedback effects on learning. Learning performance in a basic cognitive task was compared between users receiving pre-recorded, naturally spoken system feedback with neutral prosody, pre-recorded feedback with motivating (praising or blaming) prosody, or computer-synthesized feedback. The observed results provide empirical evidence that users of technical tutoring systems benefit from pre-recorded, naturally spoken feedback, and do even more so from feedback with motivational prosodic modulations matching their performance success. Theoretical implications and considerations for future implementations of spoken feedback in computer-based educational systems are discussed.} } @INCOLLECTION {Hartmann2015, author = {Hartmann, Kim and Siegert, Ingo and Prylipko, Dmytro}, title = {Emotion and Disposition Detection in Medical Machines: Chances and Challenges}, booktitle = {Machine Medical Ethics}, publisher = {Springer International Publishing}, year = {2015}, editor = {van Rysewyk, Simon Peter and Pontier, Matthijs}, pages = {317--339}, series = {Intelligent Systems, Control and Automation: Science and Engineering}, volume = {74}, doi = {10.1007/978-3-319-08108-3_19}, isbn = {978-3-319-08107-6}, abstract = {Machines designed for medical applications beyond usual data acquisition and processing need to cooperate with and adapt to humans in order to fulfill their supportive tasks. Technically, medical machines are therefore considered as affective systems, capable of detecting, assessing and adapting to emotional states and dispositional changes in users. One of the upcoming applications of affective systems is the use as supportive machines involved in the psychiatric disorder diagnose and therapy process. These machines have the additional requirement of being capable to control persuasive dialogues in order to obtain relevant patient data despite disadvantageous set-ups. These automated abilities of technical systems combined with enhanced processing, storage and observational capabilities raise both chances and challenges in medical applications. We focus on analyzing the objectivity, reliability and validity of current techniques used to determine the emotional states of speakers from speech and the arising implications. We discuss the underlying technical and psychological models and analyze recent machine assessment results of emotional states obtained through dialogues. Conclusively we discuss the involvement of affective systems as medical machines in the psychiatric diagnostics process and therapy sessions with respect to the technical and ethical circumstances.} }
