CollaborationBus Aqua: Synergies in Finding and Editing Ubiquitous Computing Configurations
Schirmer, M. and Gross, T.
Bachelor’s thesis, supervised by Tom Gross.
Abstract. With the ascent of ubiquitous computing, cooperative ubiquitous environments are becoming increasingly popular and commonly used. By facilitating communication and interaction among distributed participants of a shared information space through innovative and more natural interaction techniques, these environments leverage cooperation and collaboration between their users.
However, cooperative ubiquitous environments induce a high configuration and administration effort because they are composed of a wide range of diverse and complex components. Therefore, only especially trained and experienced system programmers and administrators are capable of configuring these environments to reflect individual scenarios and their users’ demands.
In this thesis I will introduce the concept of CollaborationBus Aqua, which aims at facilitating the configuration tasks for a cooperative ubiquitous environment in a way that end-users without programming skills may configure and create such environments on their own. A sophisticated interaction concept for a rich graphical editor puts aspects of visual programming as well as mechanisms to share configurations and explore the shared configurations of others to practice. Within the editor, the process of configuring cooperative ubiquitous environments is facilitated through familiar paradigms like drag-and-drop and the incorporation of an elegant graphical user interface.
To evaluate the concept, CollaborationBus Aqua was implemented in the form of an editor application that interfaces with a sensor-based platform for creating ubiquitous environments. The editor provides end-users with the necessary means for constructing manifold ubiquitous scenarios from the components of the sensor platform in a straightforward way. When configurations involve the similar usage of the same components, synergies emerge. These synergies are embraced and mediated through the editor. By leveraging exchange between the creators of synergetic configurations, CollaborationBus Aqua provides the basis for a novel, mediated configuration process in cooperative ubiquitous environments.

del.icio.us Browser
Beckmann, C. and Schirmer, M.
Student project for the course in visualisation techniques (Prof. Bernd Froehlich).
While the del.icio.us website offers many possibilities to search for interesting links with the help of a tag system, del.icio.us lacks a visualisation of a user’s network. Every network consists of three layers, which can be traversed in both directions. Starting on the network layer, a set of user names defines the network members. Every network member has a number of tags and every tag links to a package of bookmarks.
Our motivation was to visualise these three characteristical layers and allow the user to directly browse the sites which can be discovered, without losing contact to the network layers.
Sens-ation 3
Beckmann, C. and Schirmer, M.
Student project, supervised by Tom Gross and Tareg Egla.
During this project, we evaluated existing event notification infrastructures in comparison the the existing Sens-ation platform. The aim was to develop new ideas in the field of context management and context-aware computer systems. Besides, investigation and research on information needs and notification preferences in different contexts and environments has been of great importance in the project.
We implemented content-based routing as a pre-step towards context management, using the Publisher-Subscriber pattern. This pattern describes an information publisher, that manages the delegation of event notifications as well as Subscribers which submit a description of their information needs and notification preferences (subscription).

UbiStock
Beckmann, C. and Schirmer, M.
Student project, supervised by Tom Gross and Thilo Paul-Stueve.
This prototype application has been designed to explore the possibilities and limitations of Ubiquitous Computing. It displays stock items as spheres which are constantly flowing through space. Each sphere is mapped to a stock item and reflects changes in the stock’s share value. By means of colour, pulsation and movement speed, these changes are visible from the corner of one’s eye.
The prototype consists of two components, one being the UbiStock software and a Wacom Cintiq as hardware component. The unique Cintiq display allows direct manipulation through a stylus pen and has been very helpful to realise one of the main requirements of UbiComp systems: natural input methods.
We would like to thank Thilo Paul-Stueve for many creative and inspiring discussions which helped a lot to focus on the ubiquitous elements in the prototype.
