    ABSTRACT: The intention of the symposium on Haptic and Audio-visual stimuli at the EuroHaptics 2010 conference is to deepen the understanding of the effect of combined Haptic and Audio-visual stimuli. The knowledge gained will be used to enhance experiences and interactions in daily life. To this end, a number of key lectures have been organized and accompanying papers can be found in this proceedings. With the lectures and the interaction between the researchers at the symposium, we aim to initiate a community interested in multimodal stimulation involving haptic elements with an emphasis on experiences for entertainment, well-being and relaxation.

    ABSTRACT: From literature and through common experience it is known that stimulation of the tactile (touch) sense or auditory (hearing) sense can be used to improve people's health and well-being. For example, to make people relax, feel better, sleep better or feel comforted. In this position paper we propose the concept of combined auditory-tactile stimulation and argue that it potentially has positive effects on human health and well-being through influencing a user's body and mental state. Such effects have, to date, not yet been fully explored in scientific research. The current relevant state of the art is briefly addressed and its limitations are indicated. Based on this, a vision is presented of how auditory-tactile stimulation could be used in healthcare and various other application domains. Three interesting research challenges in this field are identified: 1) identifying relevant mechanisms of human perception of combined auditory-tactile stimuli; 2) finding methods for automatic conversions between audio and tactile content; 3) using measurement and analysis of human bio-signals and behavior to adapt the stimulation in an optimal way to the user. Ideas and possible routes to address these challenges are presented.

    ABSTRACT: Adding haptic stimulation to movies is a promising step in creating more emotionally immersive experiences. To explore the potential of this concept, we have created a wearable tactile jacket that is used to deliver movie-specific tactile stimuli to the viewer's body that are specifically targeted to influence the viewer's emotions. Immersion was evaluated in a user test using questionnaires and physiological measurements. The findings show promising effects of the haptic stimuli that need to be substantiated in further more refined user tests.

    ABSTRACT: The same stimulus can evoke different emotions for different individuals. Incorporating personalized construal of stimuli is how appraisal models differ from dimensional models of emotion. Scherer formulated a model of the cognitive antecedents of emotions and analyzed recollections of events and emotions that his participants provided. In the present study, we were interested whether Scherer's appraisal model also applies to a situation in which participants have to empathize with a photo by building a story around the event depicted. Our results show that recollecting a personal emotional event and empathizing with a photo seem to be similar processes. Results of machine-learning techniques, however, show lacking performance of classifications to express discrete emotion labels in terms of appraisal data.
