    EMS-based actuated output gestures: a design process for novices
    (Mensch und Computer 2020 - Tagungsband, 2020) Pfeiffer, Max; George, Niklas; Degbelo, Auriol
    Electrical Muscle Stimulation (EMS) has been gaining increasing attention in Human-Computer Interaction (HCI), owing to its potential to generate more expressive haptic feedback. Despite many hardware and software prototypes developed to study specific interaction aspects, designing EMS-based actuated gestures remains a complex endeavor. In this work, we present a design process for actuated gestures and a mobile app to support researchers and gesture designers during EMS-based gesture creation. The app covers the individual calibration of muscles, the composition of single movements into more complex gestures, and the playback of the pre-calibrated gestures. A user study with 12 participants, mostly non-familiar with EMS, has shown that the app was successful in supporting participants test actuated gestures. Our main contributions include a design process for actuated gestures, as well as an open-source app to support the approach and its first evaluation.

    Tight Times: Semantics and Distractibility of Pneumatic Compression Feedback for Wearable Devices
    (Mensch und Computer 2019 - Tagungsband, 2019) Löffler, Diana; Tscharn, Robert; Schaper, Philipp; Hollenbach, Melissa; Mocke, Viola
    Notifications on wrist worn devices can be delivered visual, auditory or haptic. Haptic notifications are hands and eyes-free and at the same time discrete. As an alternative to vibrotactile notifications we explore the use of compression notifications for a variety of semantic contexts. We present a prototype to deliver squeeze cues and present the results of two empirical studies focusing on context-dependent interpretation and distractibility of squeeze notifications. In the first study, 20 participants rated the desirability and intuitive understanding of squeeze-based notifications in a variety of contexts. In the second study, 39 participants completed a set of cognitive tasks interrupted by squeeze-distractors. Our observations suggest that by using simple squeeze signals it is possible to convey a range of context-dependent information that requires little learning and does not distract users from their main activity. These findings help to further investigate the use of compression notifications as an attention-preserving communication channel.
