Dieters Weinbar - Auf ein Glas in St. AntonyEpisode 166: Im Gespräch mit Kai Müller über Geschmack, Charakterköpfe und gutes EssenKai Müller ist Kunstlehrer an einem Oberstufengymnasium. Und offensichtlich versteht er sein Handwerk, denn als erstes Mal schafft er es, das Kunzilein und den Dieter zurück auf die Schulbank zu bekommen. Ansonsten ist er ein großer Fan des deutschen Bildungssystem. Er hat es in seiner eigenen Ausbildung in vollen Zügen genossen. Unter anderem hat er es zum Meisterschüler an der Kunstakademie Düsseldorf gebracht. Aber das reicht alles noch nicht, er hat mal katholische Theologie studiert und ist außerdem ein begnadeter Koch.

Nonverbal behaviors such as posture, gestures, and gaze are essential for conveying internal states, both consciously and unconsciously, in human interaction. For robots to interact more naturally with humans, robot movement design should likewise integrate expressive qualities—such as intention, attention, and emotions—alongside traditional functional considerations like task fulfillment, spatial constraints, and time efficiency.

HCI Deep DivesEmolleia – Wearable Kinetic Flower Display for Expressing EmotionsWhat we wear (our clothes and wearable accessories) can represent our mood at the moment. We developed Emolleia to explore how to make aesthetic wears more expressive to become a novel form of non-verbal communication to express our emotional feelings. Emolleia is an open wearable kinetic display in form of three 3D printed flowers that can dynamically open and close at different speeds. With our open-source platform, users can define their own animated motions. In this paper, we described the prototype design, hardware considerations, and user surveys (n=50) to evaluate the expressiveness of 8 pre-defined animated motions of Emolleia. Our...2024-10-0513 min
HCI Deep Dives“I am both here and there” Parallel Control of Multiple Robotic Avatars by Disabled Workers in a CaféRobotic avatars can help disabled people extend their reach in interacting with the world. Technological advances make it possible for individuals to embody multiple avatars simultaneously. However, existing studies have been limited to laboratory conditions and did not involve disabled participants. In this paper, we present a real-world implementation of a parallel control system allowing disabled workers in a café to embody multiple robotic avatars at the same time to carry out different tasks. Our data corpus comprises semi-structured interviews with workers, customer surveys, and videos of café operations. Results indicate that the system increases workers’ agency, enabling them to b...2024-10-0406 min
HCI Deep DivesMovement Quality Visualization for Wheelchair DanceWheelchair dance is an important form of disability art that is still subject to significant levels of ableism and art exclusion. Wheelchair dancers face challenges finding teachers and choreographers who can accommodate their needs, documenting and sharing choreographies that suit their body shapes and their assistive technologies. In turn, this hinders their ability to share creative expressions. Accessible resources and communication tools could help address these challenges. The goal of this research is the development of a visualization system grounded on Laban Movement Analysis (LMA) that notates movement quality while opening new horizons on perceptions of disabled bodies and...2024-10-0412 min
HCI Deep DivesInnermost Echoes: Integrating Real-Time Physiology into Live Music Performances
In this paper, we propose a method for utilizing musical artifacts and physiological data as a means for creating a new form of live music experience that is rooted in the physiology of the performers and audience members. By utilizing physiological data (namely Electrodermal Activity (EDA) and Heart Rate Variability (HRV)) and applying this data to musical artifacts including a robotic koto (a traditional 13-string Japanese instrument fitted with solenoids and linear actuators), a Eurorack synthesizer, and Max/MSP software, we aim to develop a new form of semi-improvisational and significantly indeterminate performance practice. It has since evolved into...2024-10-0410 min
HCI Deep Dives"Speech is Silver, Silence is Golden " Analyzing Micro-communication Strategies between Visually Impaired Runners and their GuidesRunning and jogging are popular activities for many visually impaired individuals thanks to the relatively low entry barriers. Research in HCI and beyond has focused primarily on leveraging technology to enable visually impaired people to run independently. However, depending on their residual vision and personal preferences, many chose to run with a sighted guide. This study presents a comprehensive analysis of the partnership between visually impaired runners and sighted guides. Using a combination of interaction and thematic analysis on video and interview data from 6 pairs of runners and guides, we unpack the complexity and directionality of three layers of...2024-10-0409 min
HCI Deep DivesDetecting an Offset-Adjusted Similarity Score based on Duchenne SmilesDetecting interpersonal synchrony in the wild through ubiquitous wearable sensing invites promising new social insights as well as the possibility of new interactions between humans-humans and humans-agents. We present the Offset-Adjusted SImilarity Score (OASIS), a real-time method of detecting similarity which we show working on visual detection of Duchenne smile between a pair of users. We conduct a user study survey (N = 27) to measure a user-based interoperability score on smile similarity and compare the user score with OASIS as well as the rolling window Pearson correlation and the Dynamic Time Warping (DTW) method. Ultimately, our results indicate that our...2024-10-0308 min
HCI Deep DivesLinking Audience Physiology to ChoreographyThe use of wearable sensor technology opens up exciting avenues for both art and HCI research. To be effective, such work requires close collaboration between performers and researchers. In this article, we report on the co-design process and research insights from our work integrating physiological sensing and live performance.
