A city is a public space where people find meaning by living together. Although cities are governed by city councils, it is mainly the citizens that make their own city. The contemporary cityscape is increasingly pervaded with emerging media. Recent invasions of interactive media in the cityscape, however, …

In this paper we present the design and field trial of the Dynamic Collage. The Dynamic Collage was designed to facilitate and to stimulate participation of family members in the informal care of an elderly person. The Dynamic Collage enabled relatives to update their current activity by sending a photo …

Public lighting’s primary purpose is nighttime visibility for security and safety. How to meet so many requirements of so many stakeholders? The key to developing a good plan is to relate lighting to functions of public spaces, because street lighting is more than a technical requirement, a security …

Recent years have witnessed a rise in Game Jams - organized events to create playable prototypes in a very short time frame. Game Jams offer a unique and quick way to prototype games. Beyond that, we believe Game Jams can also be seen as a design research method, situated in the research-through-design …

In software architecture, the Layers pattern is commonly used. When this pattern is applied, the responsibilities of a software system are divided over a number of layers and the dependencies between the layers are limited. This may result in benefits like improved analyzability, reusability and portability …

Designing meaningful audio for interactive applications such as video games or sonic user interfaces, presents designers with several challenges. One challenge is the fact that the perception of musical meaning involves cultural or learned aspects when it comes to tonality (Huron, 2006; Patel, 2008). …

In this paper we discuss mixed-method research in HCI. We report on an empirical literature study of the NordiCHI 2012 proceedings which aimed to uncover and describe common mixed-method approaches, and to identify good practices for mixed-methods research in HCI. We present our results as mixed-method …

A rail-guided robotic system is currently being designed for the inspection of ballast water tanks in ships. This robotic system will manipulate sensors toward the interior walls of the tank. In this paper, the influence of rail compliance on the end-effector position error due to ship movement is investigated. …

On preserving privacy whilst integrating data in connected information systems.

Many quality aspects of software systems are addressed in the existing literature on software architecture patterns. But the aspect of system administration seems to be a bit overlooked, even though it is an important aspect too. In this work we present three software architecture patterns that, when …
