US Army considers using augmented reality for mission planning

The US Army is pondering the use of augmented reality to assist with mission planning, with a research project currently underway to determine what benefits the technology could bring.

The research, which is currently being undertaken by members of the Cognitive Science Team at the Natick Soldier Research, Development and Engineering Center (NSRDEC), involves soldiers learning a mock mission route using a 3D model of a city. AR could prove a better tool than the traditional 2D maps soldiers currently use for mission planning.

“Our goal is to evaluate mobile AR as a promising candidate technology to improve mission-planning operations,” explained NSRDEC research psychologist Aaron Gardony.

“Soldiers are members of a team, but they are also multi-faceted individuals with unique preferences and aptitudes. For example, some may easily visualize three-dimensional environments from two-dimensional maps, but others may learn better using 3D imagery.”

Soldier or not, while some people can easily translate 2D renderings into 3D, for many it’s a challenge to visualise a flat plan as a fully fleshed out space, which is why AR could be very beneficial to day-to-day Army operations.

“In contrast to the one-size-fits-all approach 2D representations provide, we believe AR-based mission planning using interactive 3D maps and models could allow individuals to tailor their planning experience to their own preferences and those of their team members,” explained Gardony.

“Doing so could improve cognitive performance at both the individual and group level, leading to improved mission-planning outcomes and, ultimately, enhanced mission effectiveness.”

When viewing the model in AR, the soldiers can pan, rotate and zoom the city view, allowing them to ‘see’ the route in the manner that best suits them.

The researchers are trialling AR by tasking soldiers with learning the urban route before walking the real-life version from memory.

It is hoped that the researchers will be able to quantify any benefits that AR provides, and so make a case for the technology becoming officially adopted by the US Army for use in real-world missions.

“This study takes a novel step in evaluating AR for mission planning/route learning,” said Gardony.

“Positive results could provide a basis for future fielding of these technologies to improve mission planning and justify future research examining its impacts in other military contexts.”

Steve “Woz” Wozniak to advise hologram emoji company that he calls “groundbreaking”

Apple’s co-founder Steve “Woz” Wozniak has found himself a new gig; Woz has joined the hologram emoji company, Mojiit, as an adviser.

In his role as advisor to Mojiit, the legendary entrepreneur and engineer will help assemble a world-class engineering team in addition to bringing investors and partnerships to the newly launched startup. Wozniak will also serve as mentor to Mojiit founder, Jeremy Greene.

“I’m thrilled to join Mojiit as an advisor,” said Wozniak. “Jeremy is a natural leader, the company is groundbreaking, it’s going to change the ecommerce space, and it’s a lot of fun.”

Created in 2017, Mojiit is the latest startup technology venture from Greene. The company’s tech essentially enables users to project and share 3D hologram emojis via smartphones.

The platform turns users into emojis by scanning their face, which can then be sent to loved ones and friends. Once a Mojiit message is received, it will map the area where it is received and place the Mojiit hologram there in real time, so it works in a similar way to Pokemon Go.

“Steve is one of the best and brilliant engineers in the entire world. But outside of that, he’s a wonderful man,” said Greene. “There isn’t anyone I’d want to be in business with more than this guy. He’s a legend. Who better to learn from than the guy who created the computer?”

In addition to consumer use, businesses of all kinds can tap into hologram emojis with Mojiit’s technology.

Mojiit investors already  include NFL alum Ed Reed, and the company was able to raise a total of $1 million in its seed round of funding.

Alongside the appointment of Woz, Entourage and Ballers producer Rob Weiss recently joined the company as a creative director.

“It’s exciting to expand beyond television and film to digital platforms,” said Weiss. “Hologram technology brings incredible opportunity to entertainment and media. I’m thrilled to be leading creative at Mojiit.”

Nanoengineers send antibiotic-delivering micromotors into the body to treat cancer-causing infection

Nanoengineers have demonstrated for the first time how “micromotors” that measure half the width of a human hair can be used to transport antibiotics through the body.

Nanoengineers at the University of California San Diego tested the micromotors in mice with Helicobacter pylori infections, which can also be found in about two-thirds of the world’s population and while many people will never notice any signs of its presence it can cause peptic ulcers and stomach cancer.

The mice received the micromotors – packed with a clinical dose of the antibiotic clarithromycin – orally once a day for five consecutive days.

Afterwards, nanoengineers evaluated the bacterial count in each mouse stomach and found that treatment with the micromotors was slightly more effective than when the same dose of antibiotic was given in combination with proton pump inhibitors, which also suppress gastric acid production.

Micromotors administered to the mice swam rapidly throughout the stomach while neutralising gastric acid, which can be destructive to orally administered drugs such as antibiotics and protein-based pharmaceuticals.

Because gastric acid is so destructive to traditional antibiotics drugs used to treat bacterial infections, ulcers and other diseases in the stomach are normally taken with additional substances, called proton pump inhibitors.

But when taken over longer periods or in high doses, proton pump inhibitors can cause adverse side effects including headaches, diarrhea and fatigue. In more serious cases, they can cause anxiety or depression.

The micromotors, however, have a built-in mechanism that neutralises gastric acid and effectively deliver their drug payloads in the stomach without requiring the use of proton pump inhibitors.

“It’s a one-step treatment with these micromotors, combining acid neutralisation with therapeutic action,” said Berta Esteban-Fernández de Ávila, a postdoctoral scholar in Wang’s research group at UC San Diego and a co-first author of the paper.

The nanoengineers say that while the present results are promising, this work is still at an early stage.

To test their work, the team is planning future studies to into the therapeutic performance of the micromotors in animals and humans, and will compare it with other standard therapies used to combat stomach diseases.

UC San Diego nanoengineers also plan to test different drug combinations with the micromotors to treat multiple diseases in the stomach or in different sections of the gastrointestinal tract.

Overall, the researchers say that this work opens the door to the use of synthetic motors as active delivery platforms in the treatment of diseases.
