Industry and Simulation >> 3D printing failures shared online
(added 20/08/2013)
Seven catastropic failures are visually depicted by this BBC article. Each failure accompanied by blurb explaining what it was supposed to be, as well as where, and more imprtantly why it went wrong. It serves as a good reminder of how young this technology still is, and how frustrating it can be, for even expert users to produce 3D printed objects successfully with the way things currently stand.

A BBC article looking at the rise of the smart car – AI driven cars that will soon be able to communicate with cloud services for traffic control, communicate with the humans on board, and work in flocks to drive themselves with consideration (and a degree of literal mind-reading) of each other's positions and goals.



New to VR?

Site News: posted: 02/01/2015 We're Back!

Towards the run-up to Christmas last year, this site managed to consume nearly a hundred gigabytes in traffic. Unfortunately, when we reached the amount we had paid for, the email server decided to go down too. So that left us in a fairly amusing situation: where the site was down until the month turned over, or until we emailed the hosting service to let them know we were ok to increase it. Which couldn't happen until the site went back up...

Still, that's all behind us now. It's a new year, and a new start. For much of the second half of last year things were a bit spartan here, driven mostly by health issues amongst our people. Those issues haven't gone away, and in one case have gotten quite a bit more severe, but it's high time we got the ball rolling again. After all, the technical capabilities behind VR and AR are most decidedly not standing still, and neither should we.

Latest Term: Kinematic Motion Estimation

Kinematic motion estimation is set of techniques for trying to track in real-time three dimensions, the movement of parts of an object, usually a user. It is necessary to estimate the position change rather than track it directly because artefacts are relatively common in real-time video capture systems, and because even if the view is perfect, tracking something like a finger moving through three dimensional space, is going to be subject to a degree of error owing to the time lapse, as well as telling the system nothing about how the rest of the body has moved to enable that finger to be there at that time.

In general, all methods work by analysing the difference between frames, and then using machine vision algorithms to first reconstruct what the body parts actually are, along with non-relevant data in the visual field. Once that is done, the identifiable parts are tracked, whilst any that are not identifiable / separable from the background / blurred / hidden are reconstructed, using a variety of possible methods, primarily (but not always) revolving around matching the user to a boned model of their joints or presumed joints.

The position of identifiable body parts and how that position has changed between frames, is then enough data to use to estimate quite reliably the position of body parts that are not currently recognisable or visible based on how the person's body would have to deform at the joints in order to reach that pose, as well as the type of motion they had been undergoing in the frames leading up to this point.

It is a complex process, but a very necessary one, as it is, in essence, replicating the human capability to read body language, mannerisms, and most importantly control gestures by the interface system.

All forms of gesture interface use some degree of kinematic motion estimation, and the process is particularly vital in motion capture systems, where the end goal is to translate the user's precise body language into a virtual environment to bring life to an avatar form.

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.
