The paper describes a novel, declarative language that enables modelling ubiquitous, contextual and interactive augmented reality environments. The language, called CARL-Contextual Augmented Reality Language, is highly componentised with regards to both the structure of AR scenes as well as the presented AR content. This enables dynamic composition of CARL presentations based on various data sources and depending on the context. CARL separates specification of three categories of entities constituting an AR environment-trackable markers, content objects and interfaces, which makes the language more flexible and particularly well suited to building collective awareness systems based on ubiquitous AR-based information visualisation.

Augmented Reality (AR) is a technology that has gained an increasing interest during last years. Several fields (e.g. maintenance and education) have already started to integrate AR systems in their procedures. The preliminary results obtained from those works show a promising future for the technology. However, the number of tools that allow non-programmers to create new applications is still limited. Moreover, the great majority of these tools have still some limitations in terms of flexibility and reusability. The purpose of the platform presented in this paper is to face those problems and provide new means of AR application development. The main target of the platform is to serve as a unified system for aiding operators in the maintenance procedures in large scientific facilities. However, an important goal is that the platform can be flexible enough so it can be adapted to other fields. In order to demonstrate this flexibility, the platform has been also used to develop educational applications and a commercial educational platform.

A growing spectrum of Ubiquitous Computing (UbiComp) applications suggests that interaction with computers should be as natural and effortless as using pen, paper and language when writing. Unlike current computer environments that require a considerable amount of adaptation from users for smooth interaction, future digital interfaces are envisioned to act unobtrusively and intelligently in our environment. This dissertation describes a novel user interface approach combining Augmented Reality (AR), UbiComp and Autonomous Animated Agents into a single coherent human-computer interface paradigm that makes steps toward this vision. A significant challenge for the UbiComp community is to create efficient, natural and user-friendly interfaces since there are no standards and best practices to follow yet. Typical UbiComp scenarios include numerous mobile users roaming a large area while interacting with various stationary and mobile devices. Since the location and behavior of users and devices change rather frequently, an enormous amount of events describing changes gets generated in the environment. Processing such large data sets can be greatly overwhelming for humans, therefore an interface to a UbiComp system is expected to possess certain autonomy in order to filter and interpret relevant events and react proactively without constant user guidance and explicit instructions. By relieving users from dealing with low-level details and allowing computers to make decisions by themselves, these interfaces appear to be "smart". This thesis presents software solutions that employ reactive, autonomous and social digital assistants in UbiComp environments. These systems rely on software agent technology tailored to the needs of AR applications, where system behavior is visualized by virtual animated characters appearing on top of the real world. We discuss how autonomous animated agents can be employed to mediate communication between humans and computers in AR environments while exploiting real world attributes as input and output communication channels. The agents maintain a model of the real world by analyzing data coming from the sensors that measure physical properties such as pose, velocity, sound or light, and autonomously react to changes in the environment in accordance with the users' perception. Autonomous, emergent behavior is a novel feature in UbiComp, while awareness of real world attributes is yet unexploited by autonomous agents. This dissertation explores the requirements for context-aware animated agents concerning visualization, appearance, and behavior as well as associated technologies, application areas, and implementation details. Several application scenarios illustrate design and implementation concepts. i Kurzfassung Ubiquitous Computing (UbiComp, ubiquitäre Computertechnik) zielt darauf ab, daß die Interaktion mit Computers so natürlich und mühelos sein soll wie das Schreiben mit einem Stift auf Papier. Im Gegensatz zu derzeitigen Computersystemen, die dem Benutzer Anpassung abverlangen, agieren...
