We describe an emergent field of considerable relevance to the auditory display community – that of sonic interaction design for everyday artifacts. It is positioned at the intersection of auditory display, product interaction design, and ubiquitous computing. We describe an exploration of this field that we have undertaken in a workshop setting, with an(More)
Irradiation of skin by ultraviolet radiation in mice and humans leads to a suppression of cell-mediated immunity. This process is initiated when one of the photoreceptors in skin, trans-urocanic acid, is photoisomerized to cis-urocanic acid, an immunomodulator. High levels of L-histidine, histamine, and trans-urocanic acid are found in humans and animals(More)
UV-B radiation suppresses cell-mediated immunity. Histidine forms trans-urocanic acid (trans-UCA) enzymatically in the stratum corneum. Photoisomerization of trans-UCA to cis-urocanic acid (cis-UCA) has been proposed for the initiation of an immunosuppressive process. Many microorganisms described in the literature metabolize histidine and/or trans-UCA. Our(More)
Irradiation of skin by sunlight or ultraviolet B (UVB, 290-320 nm) brings about a downregulation of cell-mediated immunity. An action spectrum for photoimmune suppression in mice indicates that trans-urocanic acid absorbs UV photons and is isomerized to the cis-isomer in the stratum corneum. Cis-urocanic acid is subsequently shown to suppress cellular(More)
Sound design for interactive products is rapidly evolving to become a relevant topic in industry. Scientific research from the domains of Auditory Display (AD) and Sonic Interaction Design (SID) can play a central role in this development, but in order to make its way to market oriented applications, several issues still need to be addressed. Building on(More)
This paper discusses the relevance of performativity and the need for improvisational methods in sound design for interactive commodities. Both the impact on design methods and on the evaluation of experience prototypes are investigated. Several sound design techniques are proposed that help to exploit performativity and improvisation without compromising(More)
