Interaction with Media Facades – The design of interactive systems for large-scale urban screens

Media facades are a prominent example of the digital augmentation of urban spaces. They denote the concept of turning the surface of a building into a large-scale urban screen. Due to their enormous size, they require interaction at a distance and they have a high level of visibility. Additionally, they are situated in a highly dynamic urban environment with rapidly changing conditions, which results in settings that are neither comparable, nor reproducible. Altogether, this makes the development of interactive media facade installations a challenging task.

The thesis investigates the design of interactive installations for media facades holistically. A theoretical analysis of the design space for interactive installations for media facades is conducted to derive taxonomies to put media facade installations into context. Along with this, a set of observations and guidelines is provided to derive properties of the interaction from the technical characteristics of an interactive media facade installation. This thesis further provides three novel interaction techniques addressing the form factor and resolution of the facade, without the need for additionally instrumenting the space around the facades. The thesis contributes to the design of interactive media facade installations by providing a generalized media facade toolkit for rapid prototyping and simulating interactive media facade installations, independent of the media facade’s size, form factor, technology and underlying hardware.

Spatial Interaction with Mobile Projected Displays

The miniaturization of projection technology recently reached a point where battery powered pico-projectors can be carried in ones pocket. These projectors not only allow for mobile stand-alone devices but also the integration into other devices. These new class of devices allow to create ad-hoc mobile projected displays everywhere. Until today this development is mainly technology driven. While projector phones – smart- phones with integrated projector – are available, the fact that they are mainly hand-held devices, present a variety of challenges for application and interaction techniques, for the mobile projected display they provide.
In this thesis we enable spatial interaction with mobile projected displays to over- come the current technological driven approaches. We contribute by investigating the following three different directions: Applications exploiting spatial features; Analysis of spatial alignment of mobile projected displays; and Interaction techniques exploiting spatial memory techniques. Through the development and evaluation of applications and interaction techniques that rely on spatial features we exploit the users spatial memory and allow mobile projected displays to become a valuable addition of our current mobile devices.

Dual Reality Framework – Basistechnologien zum Monitoring und Steuern von Cyber-Physischen Umgebungen

Diese Promotionsarbeit untersucht die Thematik des Monitoring und der Steuerung von Cyber-Physischen Umgebungen (CPE). In diesem Zusammenhang wird das Konzept und die Umsetzung eines Dual Reality (DR) Frameworks präsentiert, welches sich aus zwei Kom- ponenten zusammensetzt: dem Dual Reality Management Dashboard (DURMAD) zur interaktiven dreidimensionalen Visualisierung von CPE und dem Event Broadcasting Service (EBS), einer modularen Kommunikationsinfrastruktur. Hierbei stellt DURMAD basierend auf dem DR-Konzept den aktuellen Status der Umgebung in einem 3D-Modell visuell dar. Gleichzeitig umfasst es weitere Auswertungs- und Darstellungsformen, welche verschiedene Formen der Entscheidungsunterstützung für Manager der Umgebung bieten. Speziell entwickelte Filtermechanismen für den EBS ermöglichen eine Vorverarbeitung der Informationen vor dem Versenden bzw. nach dem Empfangen von Events. Durch offene Strukturen können externe Applikationen an das DR-Framework angeschlossen werden. Dies wird anhand von Objektgedächtnissen, semantischen Beschreibungen und Prozessmodellen präsentiert. Basierend auf einer Formalisierung von Dual Reality wird der Begriff Erweiterte Dual Reality (DR++) definiert, welcher auch die Auswirkungen von Simulationen in DR-Applikationen umfasst. Durch eine Integration des DR-Frameworks in das Innovative Retail Laboratory werden die Potenziale der erarbeiteten Konzepte anhand einer beispielhaften Implementierung in der Einzelhandelsdomäne aufgezeigt.
