A glove designed to sense objects in the metaverse

Meta has unveiled a prototype of a glove that allows you to feel things in virtual universes. This promising accessory is far from ready to join your virtual reality headset to immerse yourself in the metaverse.

While distracting himself from the turmoil in which he locked himself FBmultiply meta ads around metaverse. Last week, Futura mentioned ReSkin, a synthetic skin capable of delivering the sense of touch to a robot’s hand, for example (read below). Always about the sense of touch, Meta’s R&D branch goes above and beyond with a glove with haptic feedback that allows you to feel the virtual world and not just with fingertips, but with the entire hand.

The prototype, which was unveiled deadCome to highlight us in the world crazy max or dunes. Instead of choosing hundreds of energy-intensive actuators that tend to heat up, the researchers found another way. They use liquids to pushair Through the small pockets in order to inflate and create a coil the pressure On the fingers or palm of the hand.

At the moment, the prototype is not yet complete, but Meta already plans to add ten times more small pockets to get it Feelings close to reality. However, by multiplying these pockets, managing them with the system becomes very complex. At this point Meta Lab is still faltering.

Tactile feedback and motor neuron sensor

Another obstacle to these gloves becoming a marketed accessory is Sustainability. For now, as we can imagine seeing it, the prototype remains brittle and unwieldy with its cables.

In terms of uses, these gloves can let you feel the printing on a file keyboard Hypothetical, for example. However, to use this default accessory, the glove must also be able to detect this intent on the wearer’s part. To do this, Meta intends to use bracelets to detect command signals from movements (motor neurons). This is how gestures can be converted into commands. Combine this process and return my touchthat’s what Meta is aiming for, already knowing that these technologies will surely only succeed in the next 10 years.

Meta: Towards a touch-sensitive electronic skin in metaverses?

Article by Sylvain Beguet published on November 4, 2021

Here’s ReSkin, a synthetic leather capable of reproducing the sense of touch. Developed by an American university, it’s one of the new research projects that Facebook/Meta has been grafted onto in order to advance its ambitions in virtual reality and metaverses.

at RoboticsOf all the senses, reproduction by touch remains the most difficult. Pick up fragile items, such as a Grape, without crushing them remains a feat to be achieved by a robotic hand. To achieve this meaning, Facebook AI/Meta has embarked on a partnership with Carnegie Mellon University in the United States.

This is where researchers developed a prototype of the tactile electronic skin, called ReSkin. skin that can be applied to robotic hands, prosthetics or “connected” gloves. With the ambition of metaverse deadit would prefer to be next to apps From the virtual reality of this Material can be employed. It will allow, for example, a person to feel what another person is touching.

ReSkin consists of a flexible, flexible rubber membrane with a thickness of 2 to 3 mm. The skin also contains fine magnetic particles. When this membrane is deformed influential On the surface, the spacing between the fine particles changes. The magnetic field Skin changes and these small differences are noted magnetometer.

Durable, simple and inexpensive

The rest is done in software with algorithms that determine the pressure to be applied, as well as the exact location of the contact on the membrane. During various tests conducted by scientists, ReSkin was able to show 90% accuracy in its interaction with surfaces. Ha sensitive The contact is accurate as it is 1 mm.

During the tests, the . program performs skin It was used to reproduce and measure stress levels for various manipulations, such as throwing or catching something, sliding on a surface, or clapping. At the end of the tests, the researchers were able to note that as a bonus, the material proved durable enough to still function after more than 50,000 interactions. Another plus: Since ReSkin does not contain any electronic component, it is inexpensive and easy to replace. The skin can be simply changed if damaged, without the need for modifications or calibrations individually.
