Mobile clients for telepresence robots are cluttered with interactive elements that either leave a little room the camera feeds or occlude them. Many do not provide meaningful feedback on robot's state and most require use of both hands. These make maneuvering difficult mobile devices. TiltWalker enables controlling robot one hand using tilt gestures smartphone. In series studies, we first just...

Several researchers stress the fact that students focus their learning according to the content in the assessment and to how this is carried out. Assessment in this particular study is not in a “usual” formal situation. Instead it refers to assessment which can be found in the interaction between teacher and pupil during hands-on work in mathematics. The analytical tools are derived from resear...

Metamaterials have become one of the hottest fields of photonics since the pioneering work of John Pendry on negative refractive index, invisibility cloaking, and perfect lensing. For practical applications, three-dimensional metamaterials are required. Here, coupling effects between individual constituents play a dominant role for the optical and electronic properties. Metamaterials can offer ...

In order to improve science education in the formative grammar school years, we combined the principles of constructivist teaching with the natural curiosity of the students in an engineering-based curriculum. This curriculum allows the students to take apart and discover for themselves how various objects work. By capitalizing on the natural curiosity of the students, and by emphasizing group,...

This paper summarizes the findings of a five-year study aimed at improving the retention rates of female students pursuing careers in engineering. The study analyzed a series of programs implemented at the University of Toledo. The programs involve hands-on design projects, research experiences, communication tools geared towards females, mentoring programs, and on-the-job rotations aimed at sp...

This paper presents the design of the visualisation and interaction in Topolor 2, an online learning system that supports social e-learning using adaptation and personalisation techniques. The main goal of this study is to investigate if and how the visualisation and interaction design based on selfdetermination theory (SDT) can improve the learning experience and learning efficiency. The goal ...

Process mining is an emerging technology in the context of Business Process Management with the goal to derive process models from observed system behavior. The global goals are: to detect previously unknown process structures, to implement consistent process controlling which may involve computation of realistic cycle times and frequency of occurrence of process pathways, or to quantify the co...
