Humans can recognize a wide range of colors and interpret them in many different ways. Besides obvious effects like highlight and beautification, these colors can influence the emotional state of humans in a significant way. While this is no new information and color psychology is a heavily discussed topic in the psychological area, little research...

Attribute Grammars are mostly used when specifying a compiler or a software
program: A context-free grammar is enriched by variables (attributes) rules and
conditions. This approach can also be adapted for a flexible search function – in
our case in the context of online courses for e-learning: In general, a course
consists of chapters – each compo...
n order to address the heterogeneity of the student´s learning behaviour at universities, it is useful to offer additional electronic material for a better understanding or to deepen the learning content. However, producing these materials is often a very time-consuming process, since often multiple views to the learning matter have to be considere...
Ambient displays provide us with information in the background of our awareness. However, as each user has individual wishes and needs of how, which and when information is presented, the acceptance of ambient displays is low.In this paper we introduce an extensible architecture for personalized ambient information.We employ a notification system t...
The Tangible Reminder Mobile brings together tangible mnemonics with ambient displays and mobile interaction. Based on the
Tangible Reminder Project we present a new interface for mobile devices that is capable of viewing and editing data linked
to real world objects. An intelligent piece of furniture equipped with RFID-sensors and digitally contro...
The design of Tangible Interfaces has already evolved since the first projects were developed. Frameworks and taxonomies have helped to understand the field of Tangible Interaction. But nevertheless the mental models of the interaction process with Tangible Interfaces seems to be surprisingly diverse. In this paper we present a comprehensive and ge...
Ambient displays provide us with information in the background of our awareness. However, as each user has individual wishes and needs of how, which and when information is presented, the acceptance of ambient displays is low. In this paper we introduce an abstract output facility which provides personalization for ambient fixtures. We employ a not...
This chapter gives an overview of the broad range of interaction techniques for use in ubiquitous computing. It gives a short introduction to the fundamentals of human-computer interaction and the traditional user interfaces, surveys multi-scale output devices, gives a general idea of hands and eyes input, specializes them by merging the virtual an...
Today's computer systems rely on standard input and output hardware which often complicates the tasks of interacting and mapping. The Tangible Reminder introduced in this paper presents an highly usable, self explanatory, real life interface. It's task is to keep track of appointments, giving an overview over their current states and reminding the...
