TL;DR: The results indicate an additive, enhancing effect of the touch-based, dynamic interaction mode especially for children who already are capable of solving the tasks by using mental rotation processes, as investigated with elementary school children.
Abstract: Mobile devices with touch screens, such as tablets are increasingly used in classrooms. Pragmatic advantages are seen in high mobility during computer-based learning due to a high portability of mobile devices and an easy online access to learning applications at places in and outside classrooms. From a psychological perspective, it is of special interest to examine how different modes of interaction with learning materials (e.g. through apps on tablets) affect performance and motivation. For example, touch screens can afford rather natural gestures and embodied interaction. For various contexts, the use of gestures to interact with information presentations (e.g. with 2-D and 3-D visualizations) has been shown to be beneficial for solving spatial tasks. It is of interest whether use of gestures can also improve learning from dynamic visual information presented on touch-based devices. We present and discuss a study in which we focused on the question of whether, for elementary school students, solving spatial tasks can be enhanced by using touch-gestures on mobile devices. Two conditions of spatial rotation tasks were compared using a within-and between subject design: an interactive, touch-based app allowing to physically rotate objects and a paper-based, static version. Elementary school students worked with both conditions, though in different orders. Findings suggest that the app-based, dynamic version improves task solving significantly with regard to success rate, mental and temporal efficiency. However, results clearly show that effects mostly exist only after children had first completed the paper-based, static trial of tasks in which they needed to mentally rotate the objects. The results indicate an additive, enhancing effect of the touch-based, dynamic interaction mode especially for children who already are capable of solving the tasks by using mental rotation processes. We investigated mental/physical rotation with elementary school children.Additive effects of touch-based, dynamic representations for spatial tasks were found.Gesture use is beneficial for rotation after mental pre-training.Effects relate to success rate, mental and temporal efficiency.

TL;DR: In this paper, the mechanical properties of single-layer transition metal dichalcogenides (TMDs) were investigated using first-principles calculations, and the results confirmed the remarkable strength of this novel 2D system.
Abstract: Transition metal dichalcogenides (TMD) are currently among the most interesting two-dimensional (2D) materials due to their outstanding properties. MoTe2 involves attractive polymorphic TMD crystals which can exist in three different 2D atomic lattices of 2H, 1T and 1T', with diverse properties, like semiconducting and metallic electronic characters. Using the polymorphic heteroepitaxy, most recently coplanar semiconductor/metal (2H/1T') few-layer MoTe2 heterostructures were experimentally synthesized, highly promising to build circuit components for next generation nanoelectronics. Motivated by the recent experimental advances, we conducted first-principles calculations to explore the mechanical properties of single-layer MoTe2 structures. We first studied the mechanical responses of pristine and single-layer 2H-, 1T- and 1T'-MoTe2. In these cases we particularly analyzed the possibility of engineering of the electronic properties of these attractive 2D structures using the biaxial or uniaxial tensile loadings. Finally, the mechanical-failure responses of 1T'/2H-MoTe2 heterostructure were explored, which confirms the remarkable strength of this novel 2D system.

TL;DR: Observations from SMSlingshot's implementation at festival exhibitions provide insight into the roles of scale, distance, and the spatial situation of media facade contexts, and will be useful for designers and developers of this new medium in urban spaces.
Abstract: Media facades (often characterized as a building's digital skin) are public displays that substitute dynamic details and information for usually static structures. SMSlingshot is a media facade system at the confluence of art, architecture, and technology design in the context of urban human-computer interaction. It represents a participative approach to public displays that enlivens public spaces and fosters civic and social dialogue as an alternative to advertising and service-oriented information displays. Observations from SMSlingshot's implementation at festival exhibitions provide insight into the roles of scale, distance, and the spatial situation of media facade contexts. The lessons learned apply to most public-display situations and will be useful for designers and developers of this new medium in urban spaces.
