    Item type: Conference Paper

    2009 International Symposium on Wearable Computers (ISWC)
    We present a novel approach to analyse and model psycho-physiological body activation patterns that emerge from physical and mental activity during daily routines. We analyse our approach on a 62 h dataset of daily routine recordings using acceleration and heart rate sensors. We present a descriptive analysis of psycho-physiological activations during the routines using a novel visualisation technique. Our results show that daily routines exhibit different psycho-physiological body activation characteristics. While physically-related routines are correlated with heart activity, mentally-related routines show activation patterns without physical activity.

  • Titan: An Enabling Framework for Activity-Aware "Pervasive Apps" in Opportunistic Personal Area Networks
    Item type: Journal Article
    Roggen, Daniel; Lombriser, Clemens; Rossi, Mirco; et al. (2011)
    EURASIP Journal on Wireless Communications and Networking
    Upcoming ambient intelligence environments will boast ever larger number of sensor nodes readily available on body, in objects, and in the user's surroundings. We envision "Pervasive Apps", user-centric activity-aware pervasive computing applications. They use available sensors for activity recognition. They are downloadable from application repositories, much like current Apps for mobile phones. A key challenge is to provide Pervasive Apps in open-ended environments where resource availability cannot be predicted. We therefore introduce Titan, a service-oriented framework supporting design, development, deployment, and execution of activity-aware Pervasive Apps. With Titan, mobile devices inquire surrounding nodes about available services. Internet-based application repositories compose applications based on available services as a service graph. The mobile device maps the service graph to Titan Nodes. The execution of the service graph is distributed and can be remapped at run time upon changing resource availability. The framework is geared to streaming data processing and machine learning, which is key for activity recognition. We demonstrate Titan in a pervasive gaming application involving smart dice and a sensorized wristband. We comparatively present the implementation cost and performance and discuss how novel machine learning methodologies may enhance the flexibility of the mapping of service graphs to opportunistically available nodes.
  • Influence of Piano Key Vibration Level on Players’ Perception and Performance in Piano Playing
    Item type: Journal Article
    Flückiger, Matthias; Grosshauser, Tobias; Tröster, Gerhard (2018)
    Applied Sciences
    In this study, the influence of piano key vibration levels on players’ personal judgment of the instrument quality and on the dynamics and timing of the players’ performance of a music piece excerpt is examined. In an experiment four vibration levels were presented to eleven pianists playing on a digital grand piano with grand piano-like key action. By evaluating the players’ judgment of the instrument quality, strong integration effects of auditory and tactile information were observed. Differences in the sound of the instrument were perceived by the players, when the vibration level in the keys was changed and the results indicate a sound-dependent optimum of the vibration levels. By analyzing the influence of the vibration levels on the timing and dynamics accuracy of the pianists’ musical performances, we could not observe systematic differences that depend on the vibration level.
  • RDSpeed: Development Framework for Speed-Based Adaptation of Web Content on Public Displays
    Item type: Conference Paper
    Sarabadani Tafreshi, Amir Esmaeil; wicki, Adrian; Tröster, Gerhard (2018)
    Computer Science Research Notes CSRN ~ WSCG 2018 Proceedings
    Viewers of public displays perceive the content of a display at different walking speeds. While responsive design (RD) adapts web content to different viewing contexts, so far only the characteristics of the device and recently the proximity of the viewers are taken into account. Yet, little attention has been paid to speed-based adaption of content and its potential in case of public displays. We therefore decided to develop a framework that would support speed-based adaptation of public display applications. In this paper, we present a framework called RDSpeed that allows developers and designers alike to easily utilize our speed-based adaptation technique and integrate them into their own applications. RDSpeed extends the standard RD definition by adding new media queries for each adaptation technique. Media queries have long been established as the go-to technique for developing responsive web applications when dealing with a variety of different devices. A user study was conducted to investigate the potential of our content adaptation technique, and possible use and extensions in the future. We show several example adaptive applications of RDSpeed, as well as discussing advantages and limitations of our framework as revealed by our user study.
