- ZeitschriftenartikelCombining Mobile Devices and Medical Workstations for Diagnostic Reading of Medical Images(i-com: Vol. 12, No. 1, 2013) Ritter, Felix; Al Issawi, Jumana; Harz, Markus; Benten, Simon; Schilling, Kathy J.Wir präsentieren ein neues Konzept für die Kombination mobiler multi-touch Geräte und medizinischer Workstations, um über mobile Geräte eine mit medizinischen Workstations vergleichbare Qualität für die Betrachtung medizinischer Bilddaten anzubieten. Das patientenzentrierte, workflow-orientierte Design verbindet hierbei ein mobiles Touch-Gerät mit medizinisch zugelassenen Monitoren und passt die Steuerung sowie die auf dem mobilen Gerät dargestellten Inhalte und Informationen dem Standort und den Zugangsrechten des Benutzers an. Das Konzept der Software basiert auf einem Diagnosesystem für die Befundung von Brust-MR-Daten und exploriert die Eignung von Touch-Interaktionen für das diagnostische Betrachten von MR Patientendaten. Wir diskutieren die Vorteile für Radiologen sowie mögliche Herausforderungen. Des weiteren werden die Ergebnisse einer informellen Evaluation des Prototypen sowie einer quantitative Studie zur Geschwindigkeit und Präzision einer neuen multi-touch Geste zur Vermessung von Objekten in medizinischen Bilddaten beschrieben.
- ZeitschriftenartikelCrowd-Powered Systems(KI - Künstliche Intelligenz: Vol. 27, No. 1, 2013) Bernstein, Michael S.Crowd-powered systems combine computation with human intelligence, drawn from large groups of people connecting and coordinating online. These hybrid systems enable applications and experiences that neither crowds nor computation could support alone.Unfortunately, crowd work is error-prone and slow, making it difficult to incorporate crowds as first-order building blocks in software. We introduce computational techniques that decompose complex tasks into simpler, verifiable steps to improve quality, and optimize work to return results in seconds. Using these techniques, we prototype a set of interactive crowd-powered systems. The first, Soylent, is a word processor that uses paid micro-contributions to aid writing tasks such as text shortening and proofreading. Using Soylent is like having access to an entire editorial staff as you write. The second system, Adrenaline, is a camera that uses crowds to help amateur photographers capture the exact right moment for a photo. It finds the best smile and catches subjects in mid-air jumps, all in realtime. These systems point to a future where social and crowd intelligence are central elements of interaction, software, and computation.
- ZeitschriftenartikelE-Government und Datensouveränität – Einblicke und Lösungsansätze(HMD Praxis der Wirtschaftsinformatik: Vol. 58, No. 5, 2021) Heine, Moreen; Wessel, DanielDie Digitalisierung hat alle Lebensbereiche erreicht – so auch den öffentlichen Sektor. Um bequeme E‑Government-Angebote bereitstellen zu können, müssen bürgerbezogene Daten zwischen Verwaltungen geteilt werden. Gleichzeitig verfolgen viele Kommunen Smart-City-Strategien und sind dabei auch auf den Zugang zu Daten der Bürger angewiesen. Damit stellt die Digitalisierung und Digitale Transformation im öffentlichen Sektor zunehmend mehr Anforderungen an die Datensouveränität der Bürger. Im privaten Bereich geschieht dieses Teilen und die Weitergabe von Daten häufig unreflektiert oder wenig informiert. Zwar stimmen viele Personen zu, dass ihnen Datenschutz wichtig sei, diese Einstellung zeigt sich allerdings oft nicht im Verhalten (Privacy Paradox). Ziel des Beitrags ist es, basierend auf aktueller Forschung, für die Datensouveränität relevante Eigenschaften von Websites im privaten und öffentlichen Kontext anhand von exemplarischen Fällen zu beschreiben. Unterschieden wird dabei zwischen öffentlichen Angeboten (z. B. Bürgerportale von Kommunen), besonders regulierten Angeboten (z. B. Portale von Banken und Versicherungen) und privaten Angeboten, deren Geschäftsmodell darauf beruht, möglichst umfangreiche Daten über ihre Nutzer zu sammeln (z. B. Soziale Netzwerke). Ziel ist es, Eigenschaften der Websites zu erfassen, die Auswirkungen auf die Datensouveränität auf Nutzerseite haben können und Gestaltungsempfehlungen zur Erhöhung der Datensouveränität, insbesondere für den öffentlichen Sektor, abzuleiten. Digitalisation has reached all areas of life—including the public sector. To provide convenient e‑government services, citizen-related data must be shared between administrations. At the same time, many municipalities are pursuing smart city strategies and are dependent on access to citizen data. Digitalisation and digital transformation in the public sector are thus placing increasing demands on the data sovereignty of citizens. In the private sector, sharing and transmission of data often happen unthinkingly or while lacking information. Although many people agree that privacy is important to them, this attitude is often not reflected in their behaviour (privacy paradox). Based on current research, this article aims to describe the characteristics of websites relevant to data sovereignty in private and public contexts using illustrative cases. A distinction is made between public services (e.g., citizens’ portals of municipalities), particularly regulated services (e.g., portals of banks and insurance companies), and private services whose business model is based on collecting as much data as possible about their users (e.g., social networks). The aim is to identify characteristics of the websites that can have an impact on data sovereignty on the user side and to derive design recommendations for increasing data sovereignty, especially for the public sector.
- ZeitschriftenartikelImmersive Inscribed Spaces – Bringing Virtuality to Written Artefacts for Humanities(i-com: Vol. 21, No. 1, 2022) Gabel, Jenny; Berns, Christof; Bosch, Sebastian; Eickmeyer, Jost; Harter-Uibopuu, Kaja; Martin, Nathalie; Osthof, Ann Lauren; Steiger, Johann Anselm; Steinicke, FrankWriting is an essential cultural technique, and the resulting artefacts are an important part of cultural heritage. The Cluster of Excellence ‘Understanding Written Artefacts’ is an interdisciplinary and cross-cultural long-term project dedicated to studying so-called ‘written artefacts (WA)’. Our work introduces immersive technologies such as virtual, augmented, and mixed reality to the research cluster for the first time. In this paper, we outline the scope of our research project and present our current implementations of immersive applications based on two scenarios involving inscribed spaces. So far, immersive technologies have not been used in academia to create research focused applications for exploring, analysing, and understanding WA within their inscribed space, including providing access to appropriate spatial and temporal contexts. Thus, we collaborate closely with researchers from the humanities to create interactive and immersive applications for the novel field of WA research. The results of our preliminary user study show high ratings in the sense of presence in the virtual environments and indicate that immersive spatial context could add new perspectives for understanding WA. We hope to provide valuable insights on the design of immersive applications to support future research in novel fields.
- WorkshopbeitragUCAI 2022: Workshop on User-Centered Artificial Intelligence(Mensch und Computer 2022 - Workshopband, 2022) Buschek, Daniel; Hauptmann, Hanna; Heuer, Hendrik; Loepp, Benedikt; Riener, Andreas; Yigitbas, EnesThe proliferation of AI-based techniques poses a range of new challenges for the design and engineering of intelligent and adaptive systems since they tend to act as black boxes and do not offer the user sufficient transparency, control, and interaction opportunities, which are considered major goals of user-centered design in the HCI field. This workshop aims at sharing and discussing recent developments at the intersection of HCI and AI, and at exploring novel methodological, technical, and interaction approaches. Researchers and practitioners with diverse disciplinary backgrounds can and should contribute to advancing the research agenda in this emerging field of human-centered artificial intelligence.
