Augmented reality contact lenses and crime-predicting AI

(ORDO NEWS) — AI has learned to predict crimes, acoustic levitation allows you to create 3D structures without touching them, and a paralyzed man was able to eat cake with the help of robotic arms.

Robotic arms controlled by the human brain helped him cope with a knife and fork

Scientists from the Applied Physics Laboratory at Johns Hopkins University, USA, have developed two prostheses – robotic arms and connected them via a brain-computer interface to the brain of a 49-year-old participant in the experiment. His hands do not work due to a partial lesion of the spinal cord.

After some training, the patient was able to cut and eat the dessert. This is one of the first demonstrations of coordinated control of two robotic arms via a brain-computer interface.

Acoustic levitation allows you to create 3D structures without touching them

Researchers at the University of Navarra have developed a system for non-contact assembly of structures. The acoustic field picks up small parts and droplets of glue, folds and fixes thin complex structures.

Since ultrasound passes through tissues, you can try to assemble such a structure in a place inaccessible to manipulation. For example, inside a living organism.

Contact lenses with augmented reality Mojo Vision opened a “portal” to another universe

Mojo Vision showed off its new development – a prototype of contact lenses with augmented reality. AR smart multifunctional contact lenses are equipped with the world’s smallest MicroLED display with a diameter of less than 0.5 mm and a resolution of 14,000 pixels per inch, which is capable of showing dynamic images in good quality.

After completing preclinical testing, Mojo Vision CEO Drew Perkins tested the company’s new development on himself.

The futuristic jumpsuit sends shocks through the user’s body, creating a realistic experience in the virtual world

A TechRadar journalist tested a Teslasuit designed for virtual reality. The development is equipped with 90 electrodes that are in contact with different parts of the user’s body.

They send discharges from 1 mA to 60 mA into the muscles. Signals of different frequency and intensity emanating from the electrodes imitate a range of feelings and sensations.

So a person in a suit can feel a blow or a shot on himself, as well as raindrops falling from above and flowing down all over his body.

New Israeli military technology can ‘see through walls’

An Israeli military tech startup called Camero-Tech has developed the Xaver 1000, a portable device that can penetrate walls ranging from thin drywall to reinforced concrete and produce high-quality images of objects hidden behind them.

It is alleged that the device is created for the military, law enforcement officers and rescuers in the aftermath of natural disasters.

The camera is able to “see” not only the position of objects, but also to recognize the faces and movements of people and animals.

AI has learned to predict crimes: now the police will know about the place of theft before the thief himself

American scientists used data on violent and property crimes in Chicago from 2014 to 2016 to create an algorithm that divides cities into roughly 100 m2 tiles.

Over a certain period, the AI ‚Äč‚Äčanalyzes what events are happening in each sector, and then predicts what crimes can be committed.

Moreover, the algorithm works well not only in Chicago, but also in other large cities – in Atlanta, Los Angeles and Philadelphia.

Tests have shown that the new development predicts events for a week ahead with an accuracy of 90%.
