FreeIMU: An Open Hardware Framework for Orientation and Motion Sensing

Orientation and Motion Sensing are widely implemented on various consumer products, such as mobile phones, tablets and cameras as they enable immediate interaction with virtual information. The prototyping phase of any orientation and motion sensing capable device is however a quite difficult process as it may involve complex hardware designing, math algorithms and programming. In this paper, we present FreeIMU, an Open Hardware Framework for prototyping orientation and motion sensing capable devices. The framework consists in a small circuit board containing various sensors and a software library, built on top of the Arduino platform. Both the hardware and library are released under open licences and supported by an active community allowing to be implemented into research and commercial projects.Comment: 10 pages, 1 figur

Materials in Participatory Design Processes

This dissertation presents three years of academic inquiry into the question of what role materials play in interaction design and participatory design processes. The dissertation aims at developing conceptual tools, based on Deweys pragmatism, for understanding how materials aid design reflection. It has been developed using a research-through-design approach in which the author has conducted practical design work in order to investigate and experiment with using materials to scaffold design inquiry. The results of the PhD work is submitted as seven separate papers, submitted to esteemed journals and conferences within the field of interaction design and HCI. The work is motivated both by the growing interest in materials in interaction design and HCI and the interest in design processes and collaboration within those fields. At the core of the dissertation lies an interest in the many different materials used during the design process: sketches, prototypes as well as the materials we shape products out of: physical and digital materials now form a unity of computation and physical materials that has given rise to a new research interest in design and materiality. The main results from the dissertation are an understanding of design materials that draws on pragmatist philosophy. The papers and overview article highlights how materials in a pragmatist perspective are more than the matter out of which we shape an idea. Rather they structure the entire process of inquiry, helping us frame problems, inspire solutions and try out these solutions in practice. This framework, developed in several of the submitted papers, is tested and illustrated through a series of experimental design cases.Comment: 89 pages, PhD Dissertation - contains introductory comments, the overview article, abstracts and links to all papers appended in the final doctoral wor
