In this paper, we describe the project; Hide&SEEK, which creates opportunities for cultural knowledge transfer through a street game experience. The game narrative is based on the concept of sharing place-based knowledge where participants assume the role of either Guest or Host of the story. The Host creates a personalized adventure route through a(More)
The studio deals with the potential of printed electronics as a way to embed electronic functionalities into everyday physical objects. Inspired by children educational toys we present a toolkit for experimenting with printed electronics and their tangible applications. It is an experimental prototyping platform for printed electronics that can be combined(More)
EN) Usually the application of digital media in authentic museum environments involves the use of equipment that could easily disturb the carefully preserved atmosphere of the place. In this demo we would like to present the project »Digitales Osmatinum« (Digital Osmantinum), a museum system that makes use of a PDA based guide system in order to introduce(More)
In this article we introduce „fingies“ a rapid prototyping framework for „Internet of Things“ (IoT) applications based on the Arduino Yún connected to hybrid sensors and actors. The hybrid sensors and actors are composed of silk-screen printed electronic circuits combined with conventional electronic parts, Surface Mounted Device (SMD) sensors and actors.(More)
In this work-in-progress, we present early comparative experiences with methods for designing tangible user interfaces (TUIs). Groups of designers used different approaches for design in the context of a concrete case study: a TUI for controlling LED lighting within hotel rooms. From the results of the groups and methods, we wish to discuss the first(More)
This empirical study is a secondary evaluation building on Franka Moritz's work “Potentials of 3D-Web-Applications in E-Commerce - Study about the Impact of 3D-Product-Presentations” [1], which was presented at the Ninth IEEE/ACIS International Conference. As in the above work, the core objective of this study is to compare 2D and 3D product(More)
