Background: This study aimed to develop an experiential approach for understanding color vision variations using virtual reality technology. Methods: A virtual classroom was developed in a three-dimensional space, and 10 university students were tested to understand color vision variations.  Results: Most participants noted that the virtual classroom was an excellent educational tool, which could help teachers understand the problems associated with [visual analog scale (VAS): mean ± standard deviation (SD), 9.55 ± 1.57] and obtain a better understanding of (VAS: mean ± SD, 9.04 ± 1.0) color vision variations.  Conclusions: Our results show that this approach enhanced the participants' understanding of color vision variations; thus, it may assist children who suffer from this variation. It is necessary to evaluate the effectiveness of this approach for teachers.

Also known as virtual reality or virtual reality environments virtual environment, is rapidly developing a comprehensive computer and interactive graphics technology, which integrates computer graphics, multimedia, artificial intelligence, multi-sensor, network parallel processing, the use of computer-generated three-dimensional space image synthesis technology to achieve the goal, through visual, hearing, touch, in order to render the graphics and animation, the viewer, "seeing is bright." Virtual reality technology is an integrated building design approach, designed to reduce labor intensity, shorten the design cycle, improve design quality, saving investment. Designers to design the building and engineering units can communicate with each other on the World Wide Web.

<div> <div> <div> <p>“Peptoids” was proposed, over decades ago, as a term describing analogs of peptides that exhibit better physicochemical and pharmacokinetic properties than peptides. Oligo-(N-substituted glycines) (oligo-NSG) was previously proposed as a peptoid due to its high proteolytic resistance and membrane permeability. However, oligo-NSG is conformationally flexible and is difficult to achieve a defined shape in water. This conformational flexibility is severely limiting biological application of oligo-NSG. Here, we propose oligo-(N-substituted alanines) (oligo-NSA) as a new peptoid that forms a defined shape in water. A synthetic method established in this study enabled the first isolation and conformational study of optically pure oligo-NSA. Computational simulations, crystallographic studies and spectroscopic analysis demonstrated the well-defined extended shape of oligo-NSA realized by backbone steric effects. The new class of peptoid achieves the constrained conformation without any assistance of N-substituents and serves as an ideal scaffold for displaying functional groups in well-defined three-dimensional space, which leads to effective biomolecular recognition. </p> </div> </div> </div>

AbstractBiofilms are microbial communities that represent a highly abundant form of microbial life on Earth. Inside biofilms, phenotypic and genotypic variations occur in three-dimensional space and time; microscopy and quantitative image analysis are therefore crucial for elucidating their functions. Here, we present BiofilmQ—a comprehensive image cytometry software tool for the automated and high-throughput quantification, analysis and visualization of numerous biofilm-internal and whole-biofilm properties in three-dimensional space and time.

AbstractThe selection and manipulation of objects in Virtual Reality face application developers with a substantial challenge as they need to ensure a seamless interaction in three-dimensional space. Assessing the advantages and disadvantages of selection and manipulation techniques in specific scenarios and regarding usability and user experience is a mandatory task to find suitable forms of interaction. In this article, we take a look at the most common issues arising in the interaction with objects in VR. We present a taxonomy allowing the classification of techniques regarding multiple dimensions. The issues are then associated with these dimensions. Furthermore, we analyze the results of a study comparing multiple selection techniques and present a tool allowing developers of VR applications to search for appropriate selection and manipulation techniques and to get scenario dependent suggestions based on the data of the executed study.
