  abstract     = {{Today, mobile devices (smartphones, tablets, etc.) are widespread and of high importance for their users. Their performance as well as versatility increases over time. This leads to the opportunity to use such devices for more specific tasks like image processing in an industrial context. For the analysis of images requirements like image quality (blur, illumination, etc.) as well as a defined relative position of the object to be inspected are crucial. Since mobile devices are handheld and used in constantly changing environments the challenge is to fulfill these requirements. We present an approach to overcome the obstacles and stabilize the image capturing process such that image analysis becomes significantly improved on mobile devices. Therefore, image processing methods are combined with sensor fusion concepts. The approach consists of three main parts. First, pose estimation methods are used to guide a user moving the device to a defined position. Second, the sensors data and the pose information are combined for relative motion estimation. Finally, the image capturing process is automated. It is triggered depending on the alignment of the device and the object as well as the image quality that can be achieved under consideration of motion and environmental effects.}},

  abstract     = {{In this paper, we address three major issues, look at their interaction and combination and present our results on how to arrive at solutions for these issues. The issues are: 1) supporting informal communication and atmosphere in organisations, 2) the role and potential of ambient displays in future work environments, and 3) the combination of mostly static artefacts that are integrated in the architectural environment with mobile devices carried by people. Our results can be considered as steps towards the design and realization of what we call “social architectural spaces” in the context of future work environments. These environments will be populated with a range of different smart artefacts that are designed to facilitate awareness and notification as well as informal communication. We address a range of spaces in office buildings including public spaces, e.g., in the hallway, the foyer, and the cafeteria that have not been the focus of research so far. In particular, we present two artefacts: the Hello.Wall, a wall-size large ambient display, and the ViewPort, a mobile handheld device. They are interacting with each other via wireless networks and different types of sensing technology. The artefacts and the software were developed in the EU-funded “Disappearing Computer”- project “Ambient Agoras: Dynamic Information Clouds in a Hybrid Worlds”.}},

  abstract     = {{We present a ubiquitous computing environment that consists of the Hello.Wall in combination with ViewPorts. Hello.Wall is a new wall-sized ambient display [4,2] that emits information via light patterns and is considered informative art. As an integral part of the physical environment, Hello.Wall constitutes a seeding element of a social architectural space conveying awareness information and atmospheres in organizations or at specific places. The display is context-dependent by reflecting identity and distance of people passing by. Hello.Wall can "borrow" other artefacts in order to communicate more detailed information. These mobile devices are called ViewPorts. People can also further interact with the Hello.Wall using ViewPorts via integrated WaveLAN and RFID technology.}},
