    ThermoPixels:Toolkit for Personalizing Arousal-based Interfaces through Hybrid Crafting

    Much research has shown the potential of affective interfaces to support people reflect on, and understand their bodily responses. Yet, people find it difficult to engage with, and understand their biodata which they have limited prior experience with. Building on affective interfaces and material-centered design, we developed ThermoPixels, a toolkit including thermochromic and heating materials, as well as galvanic skin response sensors for creating representations of physiological arousal. Within 10 workshops, 20 participants created personalized representations of physiological arousal and its real-time changes using the toolkit. We report on participants’ material exploration, their experience of creating shapes and the use of colors for emotional awareness and regulation. Reflecting on our findings, we discuss embodied exploration and creative expression, the value of technology in emotion regulation and its social context, and the importance of understanding material limitations for effective sense-making

    Towards Affective Chronometry:Exploring Smart Materials and Actuators for Real-time Representations of Changes in Arousal

    Increasing HCI work on affective interfaces aimed to capture and communicate users’ emotions in order to support self-understanding. While most such interfaces employ traditional screen-based displays, more novel approaches have started to investigate smart materials and actuators based prototypes. In this paper, we describe our exploration of smart materials and actuators leveraging their temporal qualities as well as common metaphors for real-time representation of changes in arousal through visual and haptic modalities. This exploration provided rationale for the design and implementation of six novel wrist-worn prototypes evaluated with 12 users who wore them over 2 days. Our findings describe how people use them in daily life, and how their material-driven qualities such as responsiveness, duration, rhythm, inertia, aliveness and range shape people’s emotion identification, attribution, and regulation. Our findings led to four design implications including support for affective chronometry for both raise and decay time of emotional response, design for slowness, and for expressiveness
