German databases for national and international users, using environmental databases as an example

German Databases in Biotechnology : Problems of Biotechnology Information in Germany (Beitrag von Eleonore Poetzsch)
This thesis contributes to a new discipline of science: web science, as introduced in [Berners-Lee:2006]. The big challenge is, that such a research area has only been recently postulated, however, does not yet exist in a coherent form. Designers, computer scientists, sociologists, cognitive scientists, psychologists etc. have individual perspectives on the complex and rapidly evolving interplay of technological and social infrastructure and human society. However, a well-defined discipline — unifying the scientific analysis of social and human factors to understand, but also to shape and steer web developments by informed design and engineering — is not established yet. I hope to contribute to an interdisciplinary dialogue between science, engineering and design with this thesis.
In this paper we present a general definition of the concept ’intuitive use of user interfaces’ on the basis of our current interdisciplinary work. ’Intuitive use’ is regarded as a characteristic of human-machine systems. It refers to a special kind of interaction process between users and technical systems that use the users’ intuition. The main part of the paper deals with central aspects of this definition in detail and discusses pre-conditions and restrictions of the use of the concept. The main aspects that we discuss are the design of technical systems, application and non-conscious use of previous knowledge, intuition as a non-conscious process, interaction, and effectiveness. We complement this discussion by addressing the relationship between aesthetics and intuitive use.
In this paper, we investigate possibilities and limitations of temperature change as a method for information display in mobile applications. While some widespread and well-recognized haptic displays such as force-feedback often trigger the user's immediate attention, we will focus on ambient strategies for tactile information display, that is, the display of gradual state changes in the user's periphery that do not unexpectedly interrupt her current tasks, but builds on the mind's ability for subliminal perception of environmental change instead [1, 2].
To this end, we present a series of prototypes of mobile devices that display ambient information by means of thermal change based on the thermo-electric effect [3]. In order to assess the expedience and feasibility of such a display, a series of user tests have been conducted with respect to both, the ability for thermal change recognition and a concrete application scenario for such a display.
SocialButton
(2007)
We are exploring the use of small displays as an instrument to enhance social communication. Our focus is on encouraging communication between strangers by revealing the existence of common friends. In the following we present the concept of the SocialButton, a wearable mobile device which displays aspects of friend-of-a-friend networks. A group study has provided us with an initial understanding regarding the potential of the SocialButton to influence our social environment.
Articulated paint
(2007)
In this paper we present the concept and prototype of a new musical interface that utilizes the close relationship between gestural expression in the act of painting and that of playing a musical instrument in order to provide non-musicians the opportunity to create musical expression. A physical brush on a canvas acts as the instrument. The characteristics of its stroke are intuitively mapped to a conductor program, defining expressive parameters of the tone in real-time. Two different interaction modes highlight the importance of bodily expression in making music as well as the value of a metaphorical visual representation.
Information management and content governance in large corporations is an ongoing challenge. As a case study, we present the adaptation of the elastic lists facet browser for browsing and analysing large resource collections in an intranet of a large telecommunication corporation. The application allows users to explore resource aggregations over multiple classification schemata in parallel, enabling not only personalized information access, but also improved understanding of content distributions, as well as trend analysis and target tracking. We further present empirical usability results of a first prototype from questionnaires and eye tracking studies.
