Society is affected by the consequences of data collection, and there are trends visible in law, the public debate and technology that could make a privacy-conscious future possible. We study how to avoid data collection from the perspective and the role of design, to provide a starting point for new developments in this context. We do so by presenting a portfolio that exemplifies a range of possible design contributions. We show how to design smart products for retail and smart home while avoiding data collection, how to convince clients through design, and how to use design to spread awareness. We present design notions and reflections that stem from this portfolio for the synthesis of new designs, that further explore the potential of design in practice that affords the trend of privacy.

In this paper, we inquire aesthetical aspects of the Japanese tea ceremony, described as the aesthetics in the imperfection, based on novel fabrication technologies: 3D-modeling and 3D-printing. To do so, 3D-printed utensils (chashaku and chasen) were iteratively designed for the ceremony and were evaluated using constructivist interviews, eliciting personal construct of a tea master on the beauty of these utensils. Our findings suggest that (1) beauty in the imperfection is feasible with 3D-printers, (2) such beauty can be created at the mechanical limits of the printer, creating uncontrolled yet beautiful irregularities, (3) further research can be made on the dialogue between the designer and the machine, leaving space for beautiful mechanical uncertainty. We invite designers and design researchers (1) to look at the potential of new technologies beyond what is classically expected, (2) to consider other cultural perspectives on aesthetics and on making, leading to potential novel practices in design.

Perceptual crossing is the reciprocal interplay of perceiving while being perceived. In this paper we discuss the last iteration of our ongoing research project on designing for perceptive qualities in systems of interactive products. We describe the design of explorative behavior in an artifact to enable the artifact and a person to engage in perceptual crossing. The explorative behavior is compared to the following and active behavior, the results of two earlier iterations. Through the iterations we formulated, applied and evaluated design relevant knowledge in the form of seven design notions. These notions inform design-researchers and design-practitioners on how to design for perceptive qualities in systems of interactive products. Here we specifically focus on how the artifact detects active perceptive behavior of a person, and how the artifact becomes aware of bygone perception and anticipates on future perception. An experiment shows how participants preferred the resulting explorative behavior that is closest to our theoretical framework based on phenomenology.

The Service Oriented Architecture (SOA) is used to support loosely-coupled integration of existing applications. We are investigating the possibility of creating entirely new applications based on SOA. We present a case study for a collaborative authoring application targeting groups of around five users collaborating over the Internet. We highlight the basic requirements of the application and show how these can be fulfilled by utilizing certain services accessed through standard HTTP, Jabber and JXTA set of protocols, and off-the-shelf techniques. By measuring the performance of the application in a heterogeneous environment and by providing details of an alternate service fulfilling the application's requirement, we show that SOA-based collaborative applications can be quickly designed and deployed.
