Stretchable sensor gives robots and VR a human touch

It’s not a stretch to say that stretchable sensors could change the way soft robots function and feel. In fact, they will be able to feel quite a lot.

Cornell researchers have created a fiber-optic sensor that combines low-cost LEDs and dyes, resulting in a stretchable “skin” that detects deformations such as pressure, bending and strain. This sensor could give soft robotic systems – and anyone using augmented reality technology – the ability to feel the same rich, tactile sensations that mammals depend on to navigate the natural world.

The Economic Singularity: From Capitalism’s Unplanned Obsolescence to the New Transcendent Economy

What if with the new wave of technologies, such as nanotechnology which would enable us to reprogram matter at a molecular level, we can overcome scarcity once and for all? Design would then become the most important part from start to end product which can be freely shared or have a premium in the marketplace. At any rate, this will dismantle the current social, economic, and political system, because it will become irrelevant; every institution, every value system, every aspect of our lives have been governed by scarcity: the problem of distributing a finite amount of “stuff.” There will be no need for any of today’s social institutions. In other words, when nanotech and ultra-realistic VR are commonplace, the system built on scarcity will crumble and that would herald the forthcoming “economic singularity.” #EconomicSiingularity

The current faltering economic model is suboptimal, hinders economic growth, and is not sustainable going forward.

Virtual Reality to the Rescue: Innovative pilot program transcends remote learning

When COVID-19 reared its ugly head, wreaking havoc on education for students all over the world, CSU’s human virtual reality program stepped up to meet the moment.

“We knew that teaching an entire human gross anatomy class remotely with only pictures would not be ideal for students,” said Tod Clapp, an associate professor in the Department of Biomedical Sciences and head of its human anatomy program.

Moving BMS 301, Human Gross Anatomy, to online-only instruction this summer meant that students would not only miss out on the chance to work with and learn from real human cadavers, they would also miss getting to experience the new 100-person virtual reality lab Clapp’s team built last fall.

Voxon’s US$10,000 hologram table – no glasses required

Interactive 3D images that appear to float in the air, above a table that a group of people can stand around without needing any special headsets or glasses: that’s what South Australian company Voxon Photonics has built with its US$10,000 VX1 table.

Fiction has promised us holograms for decades, with one of the most famous examples appearing in 1977’s Star Wars: A New Hope. On board the Millennium Falcon, R2D2 and Chewbacca play some sort of digital board game, interacting with figures built out of light hovering in the air above a table.

Such things have been a long time coming to the real world. VR and AR can both somewhat replicate the experience, but they require headsets. In the best case, these are a bit antisocial, stopping you from looking others in the eye. In the worst case, they completely remove the wearer from the real world to immerse them in virtual space.

UK’s first 6G innovation centre launches at University of Surrey

It will allow for near-instantaneous virtual interactions, allowing people to send a hug to a loved one or shake hands with a colleague online. Its increased capacity and speed will revolutionise virtual reality and allow for wholesale ‘teleportation of senses’, researchers claim.

Potential applications include doctors monitoring patients remotely, embracing and holding hands with a loved one who may be thousands of miles away, and having virtual meetings with no lag…

Scientists say 6G technology will be about adding a fourth dimension, ‘teleporting´ our senses to more advanced virtual worlds.

Concurrent sharing of an avatar body

The COVID-19 crisis has led to a significant increase in the use of cyberspace, enabling people to work together at distant places and interact with remote environments and individuals by embodying virtual avatars or real avatars such as robots. However, the limits of avatar embodiment are not clear. Furthermore, it is not clear how these embodiments affect the behaviors of humans.

Therefore, a research team comprising Takayoshi Hagiwara () and Professor Michiteru Kitazaki from Toyohashi University of Technology; Dr. Ganesh Gowrishankar (senior researcher) from UM-CNRS LIRMM; Professor Maki Sugimoto from Keio University; and Professor Masahiko Inami from The University of Tokyo aimed to develop a novel collaboration method with a shared avatar, which can be controlled concurrently by two individuals in VR, and to investigate human motor behaviors as the avatar is controlled in VR.

Full movements of two participants were monitored via a motion-capture system, and movements of the shared avatar were determined as the average of the movements of the two participants. Twenty participants (10 dyads) were asked to perform reaching movements with their towards target cubes that were presented at various locations. Participants exhibited superior reaction times with the shared avatar than individual reaction times, and the avatar’s hand movements were straighter and less jerky than those of the participants. The participants exhibited a sense of agency and body ownership towards the shared avatar although they only formed a part of the shared avatar.

Neuroscientists Reprogram Brain’s GPS Using Laser Beams

Neuroscientists at University College London (UCL) have used laser beams to “switch on” neurons in mice, providing new insight into the hidden workings of memory and showing how memories underpin the brain’s inner GPS system.

The study, published in the journal Cell, explains how researchers harnessed an ‘all-optical’ approach using twin lasers to simultaneously read and write the activity of ‘place cells’ (a type of neuron) in mice, as they navigated a virtual reality environment.

Remarkably, by stimulating the place cells, scientists were able to reactivate (or retrieve) the memory of a location where the mice obtained a reward, which in turn “mentally teleported” the mice, causing them to act as if they were in the rewarded place.
