Designing positive User Experience (UX) with products enables the creation of unique selling propositions. Being strongly driven by cognitive processes rather than mere product properties, UX is difficult to realize successfully. While User Experience Design (UXD) is a rather young discipline within product development other disciplines outside engineering design traditionally focus on creating experiences. We aim at transferring knowledge from those disciplines to support the design of fascinating UX with technical products. Our work is based on the ExodUX model (from Experience Oriented Disciplines to User eXperience) consisting of 41 experience from disciplines outside engineering design (e.g. sports). Our overarching goal is to support UXD based on the ExodUX approach - extending the model to a broader framework. As part of this, we documented concrete design information for all 41 experience triggers in a consistent and applicable way. Furthermore, we present a supplementing process how to implement gained knowledge of single triggers in a product development project. Finally, we provide situation specific application methodologies for the whole framework.

Nature nanotechnology 15(1), 18 - 21 (2020). doi:10.1038/s41565-019-0594-8, Molecular spin switches are attractive candidates for controlling the spin polarization developing at the interface between molecules and magnetic metal surfaces, which is relevant for molecular spintronics devices. However, so far, intrinsic spin switches such as spin-crossover complexes have suffered from fragmentation or loss of functionality following adsorption on metal surfaces, with rare exceptions. Robust metal–organic platforms, on the other hand, rely on external axial ligands to induce spin switching. Here we integrate a spin switching functionality into robust complexes, relying on the mechanical movement of an axial ligand strapped to the porphyrin ring. Reversible interlocked switching of spin and coordination, induced by electron injection, is demonstrated on Ag(111) for this class of compounds. The stability of the two spin and coordination states of the molecules exceeds days at 4 K. The potential applications of this switching concept go beyond the spin functionality, and may turn out to be useful for controlling the catalytic activity of surfaces., Published by Nature Publishing Group, London [u.a.]
