    Morphino: A nature-inspired tool for the design of shape-changing interfaces

    Get PDF
    The HCI community has a strong and growing interest in shape-changing interfaces (SCIs) that can offer dynamic af- fordance. In this context, there is an increasing need for HCI researchers and designers to form close relationships with dis- ciplines such as robotics and material science in order to be able to truly harness the state-of-the-art in morphing technolo- gies. To help these synergies arise, we present Morphino: a card-based toolkit to inspire shape-changing interface designs. Our cards bring together a collection of morphing mechanisms already established in the multidisciplinary literature and illustrate them through familiar examples from nature. We begin by detailing the design of the cards, based on a review of shape-change in nature; then, report on a series of design sessions conducted to demonstrate their usefulness in generating new ideas and in helping end-users gain a better understanding of the possibilities for shape-changing materials

    Co-designing Cards on Social Issues for Creating Educational Games

    This paper presents a participatory methodology to design cards on social issues with the purpose to democratise knowledge among co-designers on the learning content of educational games. Situated on the topic of everyday sexism, the methodology has been developed through an iterative process involving two collaborative workshops, two iterations of card design and a feedback survey. Extracting findings from the workshops and the feedback gathered on the co- designed cards, this paper presents insights that could be used to inform similar studies using cards to inspire and foster reflection on social issues

    Synthesis of Azolo[1,3,5]triazines via Rhodium(III)-Catalyzed Annulation of <i>N</i>‑Azolo Imines and Dioxazolones

    No full text
    A wide range of azolo­[1,3,5]­triazines were obtained by Rh­(III)-catalyzed annulation of <i>N</i>-azolo imines and dioxazolones. The reaction proceeds by the first catalytic C–H amidation of an imidoyl C–H bond followed by cyclodehydration. Good yields were obtained for <i>N</i>-azolo imines derived from aminoazoles and aromatic and heteroaromatic aldehydes. A range of dioxazolone amidating reagents were employed to introduce aryl, heteroaryl, and alkyl substituents. The reaction was also performed with a benchtop setup at 1 mmol scale using microwave heating

    Personal exposure to PM2.5 in Chinese rural households in the Yangtze River Delta

    High levels of PM2.5 exposure and associated health risks are of great concern in rural China. For this study, we used portable PM2.5 monitors for monitoring concentrations online, recorded personal time‐activity patterns, and analyzed the contribution from different microenvironments in rural areas of the Yangtze River Delta, China. The daily exposure levels of rural participants were 66μg/m3 (SD 40) in winter and 65μg/m3 (SD 16) in summer. Indoor exposure levels were usually higher than outdoor levels. The exposure levels during cooking in rural kitchens were 140μg/m3 (SD 116) in winter and 121μg/m3 (SD 70) in summer, the highest in all microenvironments. Winter and summer values were 252μg/m3 (SD 103) and 204μg/m3 (SD 105), respectively, for rural people using biomass for fuel, much higher than those for rural people using LPG and electricity. By combining PM2.5 concentrations and time spent in different microenvironments, we found that 92% (winter) and 85% (summer) of personal exposure to PM2.5 in rural areas was attributable to indoor microenvironments, of which kitchens accounted for 24% and 27%, respectively. Consequently, more effective policies and measures are needed to replace biomass fuel with LPG or electricity, which would benefit the health of the rural population in China

    Rhodium(III)-Catalyzed Imidoyl C–H Activation for Annulations to Azolopyrimidines

    No full text
    Azolopyrimidines are efficiently prepared by direct imidoyl C–H bond activation. Annulations of <i>N</i>-azolo imines with sulfoxonium ylides and diazoketones under redox-neutral conditions and alkynes under oxidizing conditions provide products with various arrangements of nitrogen atoms and carbon substituents. We have also probed the mechanism of this first example of Rh­(III)-catalyzed direct imidoyl C–H activation by structural characterization of a catalytically competent rhodacycle obtained after C–H activation and by kinetic isotope effects
