Speculating on biodesign in the future home

The home is a place of shelter, a place for family, and for separation from other parts of life, such as work. Global challenges, the most pressing of which are currently the COVID-19 pandemic and climate change has forced extra roles into many homes and will continue to do so in the future. Biodesign integrates living organisms into designed solutions and can offer opportunities for new kinds of technologies to facilitate a transition to the home of the future. Many families have had to learn to work alongside each other, and technology has mediated a transition from standard models of operation for industries. These are the challenges of the 21st century that mandate careful thinking around interactive systems and innovations that support new ways of living and working at home. In this workshop, we will explore opportunities for biodesign interactive systems in the future home. We will bring together a broad group of researchers in HCI, design, and biosciences to build the biodesign community and discuss speculative design futures. The outcome will generate an understanding of the role of interactive biodesign systems at home, as a place with extended functionalities

MoodLens

Using an outward-facing display mounted on eyeglasses, MoodLens seeks to help individuals express emotion who have lost the ability to speak or use facial muscles. MoodLens looks like normal eyeglasses when not in use and allows the wearer to experience eye contact normally. We collected data from non-disabled participants (i.e., potential conversation partners for the wearer) who viewed smiling, neutral and frowning emoticons on MoodLens accompanied by computerized speech. The emoticons were recognizable at conversational distances and altered the perceived emotional content of the speech significantly.Undergraduat

Considering Gut Biofeedback for Emotion Regulation

International audienceRecent research in the enteric nervous system, sometimes called the second brain, has revealed potential of the digestive system in predicting emotion. Even though people regularly experience changes in their gastrointestinal (GI) tract which influence their mood and behavior multiple times per day, robust measurements and wearable devices are not quite developed for such phenomena. However, other manifestations of the autonomic nervous system such as electrodermal activity, heart rate, and facial muscle movement have been extensively used as measures of emotions or in biofeedback applications, while neglecting the gut. We expose electrogastrography (EGG), i.e., recordings of the myoelectric activity of the GI tract, as a possible measure for inferring human emotions. In this paper, we also wish to bring into light some fundamental questions about emotions, which are often taken for granted in the field of Human Computer Interaction, but are still a great debate in the fields of cognitive neuroscience and psychology

Demonstration of Joie: A Joy-based Brain-Computer Interface (BCI) with Wearable Skin Conformal Polymer Electrodes

The 36th Annual ACM Symposium on User Interface Software and Technology (UIST ’23 Adjunct), October 29–November 01, 2023.We designed Joie, a joy-based electroencephalography (EEG) brain-computer interface (BCI). Users interact with Joie by imagining joyous thoughts and images that alter their prefrontal EEG asymmetries. These asymmetries control their character’s movement in an endless runner video game, where joyous thoughts cause left prefrontal asymmetry that leads to receiving a reward. In this demonstration, we present Joie with a wearable, dry skin conformal polymer electrode EEG headband. We conducted a pilot evaluation (11 participants, 3 training sessions per participant) to assess neurofeedback efficacy and workload. We observed that our participants were able to perform relative left activation significantly greater than right activation and create single-session improvements in resting baseline asymmetry. We also report on perceived user demand, effort and performance

Living Bits and Radical Aminos: A Workshop on Bio-Digital Interfaces for Human-Computer Interaction

As knowledge around bio-digital interaction continues to unfold, there are new opportunities for HCI researchers to integrate biology as a design and computational material. Our motivation for the workshop is to bring together interdisciplinary researchers with interest in exploring the next generation of biological HCI and exploring novel bio-digital interfaces implicating diverse contexts, scales, and stakeholders. The workshop aims to provide a space for interactive discussions, presentations, and brainstorming regarding opportunities and approaches for HCI around bio-digital interfaces. We invite researchers from both academia and industry to submit a short position paper in the following areas: Synthetic Biology, Biological Circuits, Do-It-Yourself Biology (DIYBio), Biomimetic Interfaces, Living Interfaces, Living Artefacts, and Bio-ethics. We will evaluate submissions on fit, ability to stimulate discussion, and contribution to HCI. On our website we have included examples of past work in this area to help inspire and inform position papers. Our website will host a recording of the entire workshop session with accepted papers to support asynchronous viewing for participants who are unable to attend in-person or synchronously.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Materials and Manufacturin
