Telehealth >> Toothscan Dental Health Technology
(added 18/06/2016)
A telehealth device just entering the market at time of writing, offers the chance to perform dental health scans at home, providing a daily record of tooth health to aid a dentist, or perhaps more pertinently, flag up a warning if a tooth is starting to degrade – before the pain sets in.


Computer Aided Manufacture >> 3D Printing Body Parts and Teeth: What's Next?
(added 18/06/2016)
An overview of how 3D printed prosthetics are changing dentistry. Covering in overview form, several different technologies for creating teeth: Everything from creating custom bridges to exacting perfection, to creating teeth that kill bacteria in the teeth around them, just by being used.


Computer Aided Manufacture >> Have You Heard of the 3D Printed Tooth That Kills Bacteria?
(added 18/06/2016)
When most people think of 3D printing, they think of the printer using plastic, resin, or maybe some metals. Yet, as this article demonstrates, you can 3D print with almost anything providing it can be reduced to a powder form. In this instance, a 3D printed tooth is made of a resin infused with antimicrobial quaternary ammonium salts. This means they exist right through the tooth, and as the outer surface is worn away by use, more and more antimicrobial material is released into the mouth.


Computer Aided Manufacture >> The Future of Dentistry: 3D Printing and Other Inventions
(added 18/06/2016)
This article takes a holistic overview look at how modern technologies are reshaping dentistry. Both augmented reality systems and 3D printed prosthetic teeth are covered as well as taking a look at realistically how long it will be for general roll out of these technologies to dentists around the globe.

Site News: posted: 30/05/2016 VWN Info Restored

The publicly available info on our services and policies recently vanished from our site, with any pages referencing it filling our logs with errors whenever they were accessed. The error was caused by a table in our database vanishing. Whilst the cause has not yet been ascertained, we have restored the table from backup.

Our apologies to everyone who tried to access the info over this weekend. In answer to those of you who thought we might have gone, but were not among those mailing us to notify of the error, no we have not gone, and are not going to shut up shop for the foreseeable future.

Latest Term: Region Rendering

Region Rendering, sometimes known as border rendering, is a technique more often used in pre-rendered images than in interactive VR or AR displays. However it is fundamentally compatible with both, and is a means of reducing the render workload, speeding the creation of the next frame.

Simply put, region rendering is when only a portion of the field of view is fully rendered, rather than the full thing. In pre-rendering it is often used as a tool to quickly get an idea what the final image will look like, without having to wait for the full thing to render. This saves time if the end result isn't what was hoped for.

In interactive virtual reality and augmented reality environments the concept is the same, though the reasoning is a little different.

In these interactive environments, maximising render speed is a priority. If you're going to be rendering interactively, at least 30 different renders per second are a necessity, and at least 60 it more ideal. Inevitably of course, this means the possible level of detail is much lower than a pre-rendered scene.

By using region rendering, you can skip the rendering process altogether for any areas of the environment which haven't visibly changed between frames. Thus it's possible to squeeze out more render frames per second, greater detail of render, or both, compared to rendering the entire field of view each time.

Alternate Lives >> People conform to the norm – whether that norm is physical or virtual
(added 15/01/2015)
Industry news, originally posted in January 2015, deemed too important to be allowed to fade. Often enough it is human nature to conform. This tendency makes us follow the lead of computers, even if the machines give us the wrong advice. This is the finding of a study in Springer’s journal Psychonomic Bulletin & Review that investigates how people make judgment calls after interacting within a virtual environment.


Augmenting Surgery >> Improving Robotic Surgery by integrating Augmented Reality Elements
(added 31/03/2014)
Robotic surgical procedures are carried out with the aid of a camera system attached alongside the tools on the robotic arm that is inserted into the body of a patient. A surgeon carries out the operation by seeing through the camera's eye. As such, augmented reality systems have always seemed a good fit to overlay a virtual representation of the patient's innards, along with the full size and shape of the target area, on the display screen. However, the difficulty of AR object recognition inside the body has always proven too much of a hurdle. Until now.


Artificial Intelligence >> Simple Yet Highly Effective Robotic Boost to Mass Spectrometry
(added 30/03/2014)
A group of biochemists at Georgia Tech had a dream; a dream of being able to automate the process of gathering samples for mass spectrometry. A dream whereby they could just hand the analysis tool a sample. It didn't matter what colour, shape, size, density, or anything it was. The tool would take over and just know how best to approach the problem of obtaining the sample. A nice pipe dream... until the College of Computing at the same university got wind of it.


Artificial Intelligence >> Robotic Insect: Guided by the Same stimuli
(added 09/03/2014)
For an insect, it is rather large. Six inches in length, and rolling around on tank treds rather than walking. Yet, this German robot is the same as an insect where it counts - in the brain. It possesses an embodied needs-based AI, itself running on a simplified version of the insect brain, and responds to stimuli from the world around it in the self same way a natural insect would.


Artificial Muscles >> Artificial Muscle from Fishing Line: Powerful yet Cheap
(added 04/03/2014)
When we think of artificial muscles, we tend to think of new materials that allow constructs to replicate the function of organic muscles in useful ways. We don't tend to think of existing materials in common usage as a means to create these muscles. After all if they are in common usage, they would already have been tested and discarded, right?


Avatars and Personification >> Only A Few Basic Emotional Expressions are the Root of All Others
(added 02/03/2014)
We have known for some time that different cultures perceive different facial expressions as conveying different emotional states, and likewise in different cultures different facial expressions are made. Rather than having ream after ream of options for facial expression sequence files, might there be a far better way to handle such regional differences in recognising avatar-based visual emotional states?

Embodied Avatars >> Futureworld
(added 16/04/2010)
Futureworld is the sequel to Westworld, yet it takes an entirely different direction. Meant to be the film that spun the Westworld franchise into an anthology set, instead it was the film that buried it. Futureworld has some great ideas, and like many films of the era, is a goldmine of nuggets concerning robotic technology, virtual reality, augmented reality and social implications.


Pure Research >> Programming the Universe: A Quantum Computer Scientist Takes on the Cosmos
(added 25/03/2010)
Programming the Universe is a Simulation Argument book. Lloyd, a professor at MIT, works in the vanguard of research in quantum computing: using the quantum mechanical properties of atoms as a computer. He contends that the universe itself is one big quantum computer producing what we see around us, and ourselves, as it runs a cosmic program.


Pure Research >> Decoding Reality: The Universe as Quantum Information

Decoding Reality is very much a Simulation Argument book. In its pages, physicist Vlatko Vedral argues that we should regard the entire universe as a gigantic quantum computer.


Teaching and Training via VR >> Women and Gaming: The Sims and 21st Century Learning
(added 21/02/2010)
Video games have become both big business and a technological focal point for new forms of learning. Today games are not just played; players engage in game design, write fan fiction, and organise themselves into collaborative learning communities. In these communities players acquire 21st century skills in technology, but, in the best of these communities, they hone these technical skills and strengthen emotional and social intelligence.
