No peeking: Humans play computer game using only direct brain stimulation

Researchers have published the first demonstration of humans playing a simple, two-dimensional computer game using only input from direct brain stimulation — without relying on any usual sensory cues from sight, hearing or touch.

Phantom movements in augmented reality helps patients with chronic intractable phantom limb pain

A novel method of treating phantom limb pain has been developed using machine learning and augmented reality. This approach has been tested on over a dozen of amputees with chronic phantom limb pain who found no relief by other clinically available methods before. The new treatment reduced their pain by approximately 50 per cent, reports a clinical study.

A good combination: Model and experiment for a deeper look

Doctors performing medical check-ups want a full picture of the patient’s health without using the scalpel. Engineers who want to investigate the stability of a bridge without cutting into it are in the same position. Non-destructive testing methods play a major role in guaranteeing quality and safety, driving substantial interest in refined methodologies. Now researchers have developed a method that gives a precise picture of the inner world of objects combining a computerized model and experiment.

Video Games: When lag time gets you shot

Do you always get ‘shot’ playing computer games? Do you, like a sore loser, also blame the equipment? Actually, rather surprisingly, you might be justified.

What can Pokémon Go teach the world of conservation?

Launched in July this year, Pokémon Go has become a global phenomenon, reaching 500 million downloads within two months of release. The augmented reality game, designed for mobile devices, allows users to capture, battle and train virtual creatures called Pokémon that appear on screen as if part of the real-world environment. But can the game’s enormous success deliver any lessons to the fields of natural history and conservation?

Atomic beltway could solve problems of cosmic gravity

When is a traffic jam not a traffic jam? When it’s a quantum traffic jam, of course. Only in quantum physics can traffic be standing still and moving at the same time, say researchers.

Robots help position interventional needles

Finding the ideal position for interventional needles – as used in biopsies, for instance – is a difficult and time-consuming process. This can now be performed automatically, using a robotic arm to place a needle guide for the doctor at the optimal insertion point. With robotic assistance, doctors need five minutes to position the needle, as opposed to 30 minutes with conventional techniques.

New antireflective coating reduces stray light and reflections

Transparent plastic optical lenses can be manufactured cheaply and in any shape. However, a downside is that they reflect light just as much as glass does. Researchers are exhibiting a new type of antireflective coating that significantly reduces stray light and reflections from plastic lenses. Not only does this improve the performance of cameras and headlights, it’s also good news for virtual reality technologies.
