Next-generation air-navigation displays

Future airplanes could be fitted with several short-throw wide-angle LED projectors to create a seamless tiled cockpit interactive air-navigation display

Projection technology for future airplane cockpits

A large single interactive display designed for the cockpits of future airplanes, as it was developed during the European Project ODICIS is presented. It is based on an array of several short throw wide angle projectors resulting in a seamlessly tiled display. The project results are discussed in this contribution

Projection systems for vehicle displays

Direct view displays are nowadays common in vehicle displays of various nature to convey information. They are mostly LCD-based and benefit from the maturity and reliability of this well-developed technology. However, they also have some drawbacks that prevent them from being completely adapted to the wishes of human-machine interface designers. Prominent aspects in this respect are the more or less fixed form-factor, the limited curveability and the problematic tiling of several displays with visible seams. These points make it difficult to use these displays on complex, arbitrary shaped surfaces as encountered in many vehicle environments and are thus an obstacle to create high-information content screens in novel human-machine interfaces in the confined spaces of vehicles. Projection technology is a suitable candidate to solve many of these problems. Front projection techniques, e.g. head-up displays on the front-window of cars are coming into use1; the specialized versions of these in (fighter-) planes are already common for quite some years. These approaches however do not fully address the demands of the HMI developers for creating more complex interfaces. Recent developments open up the possibility to use the potential of the projection technology to the full. Rear-projection systems that allow the creation of free-form displays in cars are currently being investigated. For airplane environments, which provide an even greater challenge due to the safety regulations, a rear projection based, reconfigurable single large cockpit display was developed4. It allows the use of a new paradigm in human-machine interface, featuring a cockpit-wide curved screen surface with touch capabilities. It uses LCOS microdisplays, a high performance LED illumination system, custom short throw projection lenses and accompanying screen. The whole system comprises of five seamlessly tiled projectors providing a non-flat, T-shaped dashboard. The screen is equipped with a multi-touch capable interface based on optical detection, making it possible to place both information and instruments at any position, depending on the situation

Projection displays in avionics

Avionics represents a specialized area of display applications. A possible future development in this field is a single display cockpit environment with touch input capabilities. Such a seamless, tiled cockpit display based on several short throw wide angle projectors is being developed in the European Project ODICIS. The current results are discussed in this contribution

FRET-based dynamic structural biology: Challenges, perspectives and an appeal for open-science practices.

Single-molecule FRET (smFRET) has become a mainstream technique for studying biomolecular structural dynamics. The rapid and wide adoption of smFRET experiments by an ever-increasing number of groups has generated significant progress in sample preparation, measurement procedures, data analysis, algorithms and documentation. Several labs that employ smFRET approaches have joined forces to inform the smFRET community about streamlining how to perform experiments and analyze results for obtaining quantitative information on biomolecular structure and dynamics. The recent efforts include blind tests to assess the accuracy and the precision of smFRET experiments among different labs using various procedures. These multi-lab studies have led to the development of smFRET procedures and documentation, which are important when submitting entries into the archiving system for integrative structure models, PDB-Dev. This position paper describes the current 'state of the art' from different perspectives, points to unresolved methodological issues for quantitative structural studies, provides a set of 'soft recommendations' about which an emerging consensus exists, and lists openly available resources for newcomers and seasoned practitioners. To make further progress, we strongly encourage 'open science' practices
