  • Towards Somaesthetic Smarthome Designs: Exploring Potentials and Limitations of an Affective Mirror
    Chi Tai Dang, Ilhan Aslan, Florian Lingenfelser, Tobias Baur, and Elisabeth André,
    IoT 2019, Proceedings of the 9th International Conference on the Internet of Things (IoT 2019) (Bilbao, Spain). ACM, NY, USA. In Press.

    Have you ever experienced a mirror that not only “sees” how you see yourself, but tells you how others perceive you? May such a smartmirror help not only adapt/improve oneself externally (look) but also internally (mood, emotions)? What are the expectations, fears (privacy)? The acceptance of such a smart thing requires approaches that go beyond technology-driven designs. In this paper …

  • Calibration Transfer for Food Recognition Models for E-Noses
    Andreas Seiderer, Chi Tai Dang and Elisabeth André,
    IoT 2019, Proceedings of the 9th International Conference on the Internet of Things (IoT 2019) (Bilbao, Spain). ACM, NY, USA. In Press.

    Gas sensors using the low-priced MOS technique face several problems that reduce their applicability for classification tasks. In literature, several methods can be found that try to alleviate these problems. In this paper, we focus on the problem that the behavior of different sensors (of same type) results in different data even for the same gas concentrations …

  • Put that Hologram there – Probing Mobile Interaction Experiences for a Vision of Mixed Material Public Spaces
    Ilhan Aslan, Chi Tai Dang, Ruben Schlagowski, Michael Dietz, Fabian Brain, and Elisabeth André,
    IoT 2019, Proceedings of the 9th International Conference on the Internet of Things (IoT 2019) (Bilbao, Spain). ACM, NY, USA. In Press.

    The materiality of urban spaces has been changing by progress and consequently the way we, as townsmen or visitors, interact in these spaces is changing. For example, within the last decade using a mobile digital bus ticket has become a common practice in many cities around the world. Contemporary progress in mobile augmented reality technologies has already introduced novel pervasive displays, such as Microsoft’s HoloLens, which allows to display mixed realities containing tangible real and “intangible” holographic objects. Now, we seem to be at a crossroads …

  • Viewing Experience of Augmented Reality Objects as Ambient Media – A Comparison of Multimedia Devices
    Ilhan Aslan, Chi Tai Dang, Björn Bittner, Michael Dietz, Michael Filipenko and Elisabeth André,
    AmI 2019, Proceedings of the 2019 European Conference on Ambient Intelligence (AmI 2019) (Rome, Italy). Springer. In Press.

    Holograms (i.e., visual augmented reality objects embedded in real space) as mediums are being deployed in diverse contexts, such as home, mobile, and work. We argue that the user experience of holograms is mediated by the type …

  • Indoor Air Quality and Wellbeing – Enabling Awareness and Sensitivity with Ambient IoT Displays
    Andreas Seiderer, Ilhan Aslan, Chi Tai Dang and Elisabeth André,
    AmI 2019, Proceedings of the 2019 European Conference on Ambient Intelligence (AmI 2019) (Rome, Italy). Springer. In Press.

    The quality of indoor air exerts influence on the wellbeing of people. However, people rarely notice a constant and creeping deterioration of indoor air. Especially in enclosed places where several people get together, like meeting rooms, school rooms and public transportation, bad air quality might cause a reduction of cognitive performance, increased headache, fatigue and sleepiness. This paper describes and discusses a privacy respecting system, built with low cost IoT components and open-source software, that …

  • Of Smarthomes, IoT Plants, and Implicit Interaction Design
    Björn Bittner, Ilhan Aslan, Chi Tai Dang, and Elisabeth André,
    TEI 2019, Proceedings of the Thirteenth International Conference on Tangible, Embedded and Embodied Interaction (Tempe, Arizona, USA). ACM, NY, USA.

    There seems to be a danger to carelessly replace routine tasks in homes through automation with IoT-technology. But since routines such as watering houseplants also have positive influences on inhabitants’ wellbeing, they should be transformed through carefully performed designs. To this end, an attempt to use technology for augmenting a set of houseplants’ non-verbal communication capabilities is presented. First, we describe in detail how implicit interactions have been designed to support inhabitants in watering their plants through meaningful interactions. Then, we report on a field study …

  • Theodor: A Step Towards Smart Home Applications with Electronic Noses
    Chi Tai Dang, Andreas Seiderer, Elisabeth André,
    iWOAR 2018, Proceedings of the 5th international Workshop on Sensor-based Activity Recognition and Interaction (Berlin, Germany). ACM, NY, USA.

    This paper presents preliminary results of the ongoing project TheOdor which explores the potential of electronic noses that make use of commodity gas sensors (MOS, MEMS) for applications in the smarthome, for example to classify human activities based on the odors that activities generate. We describe the system and its components and report on classification results from validation experiments …

    Chi Tai Dang, Elisabeth André,
    MuC 2018, Mensch und Computer 2018 – Tagungsband (Dresden, Germany). Gesellschaft für Informatik e.V., Bonn.

    This paper presents the results of an initial survey that examines the acceptance of autonomous behavior and cloud dependency in smarthomes. In addition, this paper presents concerns on both topics. Depending on whether someone already lives in a smarthome or not, the acceptance changes …

  • Exploring Opportunistic Ambient Notifications in the Smart Home to Enhance Quality of Live
    Andreas Seiderer, Chi Tai Dang, Elisabeth André,
    Fullpaper, ICOST 2017, Proceedings of the 15th International Conference On Smart homes and health Telematics (Paris, France), Springer.

    Smart home technology became more and more widespread within recent years. They aim to make life easier and taking over unwanted tasks. In traditional homes, it is often not clear whether all windows and doors of a house are closed before inhabitants leave the home or go to sleep. However, this can be easily addressed by smart homes. We present a system based on opportunistically located ambient lights that assist inhabitants of a smart home in answering this question …

  • Tabletop Interaction Beyond Touch – Interaction On, Above, Around, and Across Tabletop Surfaces
    Chi Tai Dang
    Dissertation 2016, Augsburg University (Germany)

    Interactive or digital tabletops are table-like embedded computing systems, which provide a large unified display and input surface. Touch input and tangible artifacts on the tabletop surface represent the most prominent, thus, most often implemented input mechanisms. However, digital tabletops provide much more potential for interaction techniques …

  • A Framework for the Development of Multi-Display Environment Applications Supporting Interactive Real-Time Portals
    Chi-Tai Dang, Elisabeth André
    Proceedings of the 6th Conference on Engineering Interactive Computing Systems (EICS 2014)

    Advances in multi-touch enabled interactive tabletops led to many commercially available products and were increasingly deployed at places beyond research labs, for example at exhibitions, retail stores, or showrooms. At the same time, small multi-touch devices, such as tablets or smartphones, became prevalent in our daily life. When considering both trends, occasions and scenarios where tabletop systems and mobile devices form a coupled interaction space are expected to become increasingly widespread …
