Das „Soap Bubble Interface“ – eine ephemere Benutzungsschnittstelle
No full textDieser Beitrag beschreibt das „Soap Bubble Interface“ und liefert hiermit ein Beispiel für die Verwendung ephemerer Materialien zur Gestaltung von User Interfaces für die Mensch-Computer-Interaktion. Die Elemente der Benutzungsschnittstelle sind einzelne vom Benutzer mit Hilfe einer Maschine auf einer Oberfläche erzeugte Seifenblasen. Der Benutzer kann mit einem Computer interagieren, indem er die Seifenblasen vorsichtig mit dem Finger oder durch Pusten bewegt. Position und Größe der Blasen werden vom Computer erkannt. Visuelles Feedback ist durch Illumination der wahlweise mit Rauch gefüllten Seifenblasen möglich. Die Installation wurde als eine konkrete Implementierung einer ephemeren Benutzungsschnittstelle entwickelt und dient der Exploration von Materialitätskonzepten für Tangible User Interfaces
The Walking Talking Stick: Understanding Automated Note-Taking in Walking Meetings
Full text linkWhile walking meetings offer a healthy alternative to sit-down meetings, they
also pose practical challenges. Taking notes is difficult while walking, which
limits the potential of walking meetings. To address this, we designed the
Walking Talking Stick -- a tangible device with integrated voice recording,
transcription, and a physical highlighting button to facilitate note-taking
during walking meetings. We investigated our system in a three-condition
between-subjects user study with thirty pairs of participants (=60) who
conducted 15-minute outdoor walking meetings. Participants either used clip-on
microphones, the prototype without the button, or the prototype with the
highlighting button. We found that the tangible device increased task focus,
and the physical highlighting button facilitated turn-taking and resulted in
more useful notes. Our work demonstrates how interactive artifacts can
incentivize users to hold meetings in motion and enhance conversation dynamics.
We contribute insights for future systems which support conducting work tasks
in mobile environments.Comment: In CHI 202
Understanding Perception of Human Augmentation: A Mixed-Method Study
Full text linkTechnologies that help users overcome their limitations and integrate with the human body are often termed “human augmentations”. Such technologies are now available on the consumer market, potentially supporting people in their everyday activities. To date, there is no systematic understanding of the perception of human augmentations yet. To address this gap and build an understanding of how to design positive experiences with human augmentations, we conducted a mixed-method study of the perception of augmented humans (AHs). We conducted two scenario-based studies: interviews (n = 16) and an online study (n = 506) with participants from four countries. The scenarios include one out of three augmentation categories (sensory, motor, and cognitive) and specify if the augmented person has a disability or not. Overall, results show that the type of augmentation and disability impacted user attitudes towards AHs. We derive design dimensions for creating technological augmentations for a diverse and global audience
Leveraging driver vehicle and environment interaction: Machine learning using driver monitoring cameras to detect drunk driving
Full text linkExcessive alcohol consumption causes disability and death. Digital
interventions are promising means to promote behavioral change and thus prevent
alcohol-related harm, especially in critical moments such as driving. This
requires real-time information on a person's blood alcohol concentration (BAC).
Here, we develop an in-vehicle machine learning system to predict critical BAC
levels. Our system leverages driver monitoring cameras mandated in numerous
countries worldwide. We evaluate our system with n=30 participants in an
interventional simulator study. Our system reliably detects driving under any
alcohol influence (area under the receiver operating characteristic curve
[AUROC] 0.88) and driving above the WHO recommended limit of 0.05g/dL BAC
(AUROC 0.79). Model inspection reveals reliance on pathophysiological effects
associated with alcohol consumption. To our knowledge, we are the first to
rigorously evaluate the use of driver monitoring cameras for detecting drunk
driving. Our results highlight the potential of driver monitoring cameras and
enable next-generation drunk driver interaction preventing alcohol-related
harm
Do You Mind? User Perceptions of Machine Consciousness
Full text linkThe prospect of machine consciousness cultivates controversy across media, academia, and industry. Assessing whether non-experts perceive technologies as conscious, and exploring the consequences of this perception, are yet unaddressed challenges in Human Computer Interaction (HCI). To address them, we surveyed 100 people, exploring their conceptualisations of consciousness and if and how they perceive consciousness in currently available interactive technologies. We show that many people already perceive a degree of consciousness in GPT-3, a voice chat bot, and a robot vacuum cleaner. Within participant responses we identified dynamic tensions between denial and speculation, thinking and feeling, interaction and experience, control and independence, and rigidity and spontaneity. These tensions can inform future research into perceptions of machine consciousness and the challenges it represents for HCI. With both empirical and theoretical contributions, this paper emphasises the importance of HCI in an era of machine consciousness, real, perceived or denied
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
