Considering the current development of commercial head-mounted displays (HMD), it is likely that HMDs will be widely used in the near future. Therefore, it becomes feasible to build systems that rely on HMD technology. Real-world search engines aim at supporting the user’s search capabilities in the real world. HMDs are a possible device to guide a user towards the location of an object. To ens...

With the fast advance of real-time computer graphics, head-mounted displays (HMDs) have become popular tools for 3D visualization. One of the most promising and challenging future uses of HMDs, however, is in applications where virtual environments enhance rather then replace real environments. The difficulty comes from the fact that the relative registration of real and virtual environments is...

In high reliable industries, where critical information is often given in real time, Head-Mounted Displays (HMDs) may support workers. Especially if mobility is needed, like in maintenance or some fields of medicine, HMDs can display this critical information directly within the field of view. However, in a study presented on last year ́s conference of HFES-Europe we showed that participants rea...

The synthesis and attempted isolation of neutral bis(allyl)strontium [Sr(C(3)H(5))(2)] (1) resulted in the isolation of potassium tris(allyl)strontiate K[Sr(C(3)H(5))(3)] (2). In situ generated 1 shows a pronounced Brønsted basicity, inducing polymerisation of THF. Ate complex 2 crystallises as [K(THF)(2){Sr(C(3)H(5))(3)}(THF)](∞) (2·(THF)(3)). The salt-like solid state structure of 2·(THF)(3) ...

Most virtual reality (VR) systems employ head-mounted displays (HMDs). Many such systems are also designed to provide stereo depth and use head tracking to enable the virtual world to change in response to the user's movements. The current state of HMDs and other VR technology falls short of accurately simulating many aspects of the visual world. Differences between the real world, for which th...

Real-time three-dimensional (3D) interactive displays refer to display devices servo to the line of sight of a user, allowing not only free head motion, but also potentially and importantly full body mobility. Ideally, one could wish for such capability to exist without the need to wear any viewaided device. However, unless a display system could be created in space, anywhere and anytime, a sim...

Head-mounted display (HMD) technologies find a variety of applications in the field of 3D virtual and augmented environments, 3D scientific visualization, as well as wearable displays. While most of the current HMDs use head pose to approximate line of sight, we propose to investigate approaches and designs for integrating eye tracking capability into HMDs from a low-level system design perspec...

Developing N-heterocyclic carbene (NHC) chemistry of simple organomagnesium compounds, this study reports the synthesis, X-ray crystallographic, and NMR spectroscopic characterization of three such new carbene complexes. The 1 : 1 alkyl magnesium amide : carbene complexes nBuMg(TMP)·IPr 1 and nBuMg(HMDS)·IPr 2 both exist as mononuclear complexes in the crystal but differ in solution as 2 remain...

Research in multi-document summarization has focused on newswire corpora since the early beginnings. However, the newswire genre provides genre-specific features such as sentence position which are easy to exploit in summarization systems. Such easy to exploit genre-specific features are available in other genres as well. We therefore present the new hMDS corpus for multi-document summarization...

We propose the combination of two recently introduced methods for the interactive visual data mining of large collections of data. Both, Hyperbolic Multi-Dimensional Scaling (HMDS) and Hyperbolic Self-Organizing Maps (HSOM) employ the extraordinary advantages of the hyperbolic plane (H2): (i) the underlying space grows exponentially with its radius around each point ideal for embedding high-dim...
