<p>The commentary is partially critical. Mr Konrad Erzberger a shareholder of the TUI concern, based in Germany, operating worldwide. Half supervisory board made up representatives and half appointed by employees. In judgement, Court Justice European Union (CJEU) answered question, whether it was compliant with Articles 18 45 Treaty on Functioning (TFEU) stating that Member State should g...

We present our ongoing design of Snakey, a tangible user interface (TUI) dedicated to the field of reservoir geosciences and engineering. Our design of Snakey emphasizes intuitive manipulation and interaction with 3D curves, common to underground well path exploration and planning. Snakey is not designed to replace the traditional CAD reservoir well path planning tools, but rather to augment th...

In this paper, we discuss the value of semiotics to inquire tangible user interfaces (TUI) in humancomputer interaction (HCI). Drawing on Peirce’s three types of representation – icon, index, and symbol (Peirce, Houser, & Kloesel, 1998) – we analyze signification processes in the design of tangible UIs. As a case study, we draw on several prototypical interfaces and analyze their semiotic struc...

A king u in a tournament is a player who beats any other player v directly or indirectly. That is, either u → v (u beats v) or there exists a third player w such that u→ w and w → v. A sorted sequence of kings in a tournament of n players is a sequence of players, S = (u1, u2, . . . , un), such that ui → ui+1 and ui in a king in sub-tournament Tui = {ui ,ui+1, . . . , un} for i = 1,2, . . . , n...

Physical prototyping is an important part in research and development of tangible user interfaces (TUIs). On the way from the idea to a working prototype, hardware prototypes usually have to be crafted repeatedly in numerous iterations. However, this can be very timeand cost-intensive when non-standard, expensive hardware components are part of the design. This brings us to think about digital ...

Desert springs, which harbor diverse and endemic invertebrate assemblages, are often used as refuge habitats for protected fish species. Additionally, many of these springs have been colonized by invasive fish species. However, the potential impacts of recently established fish populations on invertebrate communities in desert springs have been relatively unexplored. We conducted a mesocosm exp...

Recent development of three-dimensional (3D) and four-dimensional ultrasound (4D), specially using tomographic ultrasound image (TUI), inverse mode, automatic volume calculation (AVC) and virtual organ computer-aided analysis (VOCAL), provided us with new possibilities to study fetal low urinary obstructions before 24th week. Ultrasound scan studies have been conducted in order to provide infor...

Tangible user interfaces (TUI) promise to enable natural and intuitive interaction with digital information through the physical environment. They are not limited to the interactions of a single person, but also support collaboration among – even dislocated – groups. Technological advances make it possible to integrate sensors and actuators as well as wireless communication and processing techn...
