Emerging technologies | Digital Watch Observatory

AR and VR are rapidly emerging fields, with applications within the gaming industry, as well as in the health, education, and development sectors.

What is augmented reality? The technology allows users to view the real-world environment with augmented (added) elements, generated by digital devices. One famous example in recent years was Pokemon Go, a game for mobile devices in which players chase imaginary digital creatures (visible on their mobile phones) around physical locations.

What is virtual reality? VR goes a step forward, and replaces the real world entirely with a simulated environment, created through digitally-generated images, sounds, and even touch and smell. Using special equipment, such as a custom headset, the user can explore a simulated world or simulate experiences such as flying or skydiving.

What are the main applications of augmented and virtual reality? In architecture and engineering, AR and VR allow architects to see their building plans come to life before being built. In the business sector, these technologies allow products to be previewed or customised, thus improving productivity and offering new marketing possibilities.

In health, AR can provide surgeons with additional information when operating on a patient, such as heartbeat and blood pressure monitoring and virtual x-rays. By using AR, education can be made more interactive and fun, bringing abstract concepts to life. VR can create educational environments that are otherwise inaccessible in real-life. It can also provide a framework for students to develop skills without the real-world consequences of failing (e.g. virtual flight simulators, military and medical training).

What are the policy issues associated with AR and VR? Beyond their potential, these technologies also come with challenges. Pokemon Go, for example, generated concerns around a wide range of issues, such as public safety, cybersecurity, and privacy and data protection.

Privacy issues are common across other AR applications: Since they often track movements and data, massive amounts of data are generated about the whereabouts of users. On the economic side, AR can create new business models, raising questions about taxation, jurisdiction, and customer protection.

With VR, the main concerns are health and safety. When people are exposed to VR environments for extensive periods of time, there could be negative consequences for their physical health (such as motion sickness and disorientation) as well as their mental health (such as addiction and interpersonal communication).

Drones setting a new standard in ocean rescue technology

Drones setting a new standard in ocean rescue technology


Last month, two young paddleboarders found themselves stranded in the ocean, pushed 2,000 feet from the shore by strong winds and currents. Thanks to the deployment of a drone, rescuers kept an eye on them the whole time and safely brought them aboard a rescue boat within minutes.

In North Carolina, the Oak Island Fire Department is one of a few in the country using drone technology for ocean rescues. Firefighter-turned-drone pilot Sean Barry explained the drone’s capabilities as it was demonstrated on a windy day. 

“This drone is capable of flying in all types of weather and environments,” Barry said.

Equipped with a camera that can switch between modes — including infrared to spot people in distress — responders can communicate instructions through a speaker. It also can carry life-preserving equipment.

The device is activated by a CO2 cartridge when it comes in contact with water. Once triggered, it inflates into a long tube, approximately 26 inches long, providing distressed swimmers something to hold on to.

In a real-life rescue, after a 911 call from shore, the drone spotted a swimmer in distress. It released two floating tubes, providing the swimmer with buoyancy until help arrived.

Like many coastal communities, Oak Island’s population can swell from about 10,000 to 50,000 during the summer tourist season. Riptides, which are hard to detect on the surface, can happen at any time.

Every year, about 100 people die due to rip currents on U.S. beaches. More than 80% of beach rescues involve rip currents, if you’re caught in one, rescuers advise to not panic or try to fight it, but try to float or swim parallel to the coastline to get out of the current.

Oak Island Fire Chief Lee Price noted that many people underestimate the force of rip currents.

“People are, ‘Oh, I’m a good swimmer. I’m gonna go out there,’ and then they get in trouble,” Price said.

For Price, the benefit of drones isn’t just faster response times but also keeping rescuers safe. Through the camera and speaker, they can determine if someone isn’t in distress.

Price said many people might not be aware of it. 

“It’s like anything as technology advances, it takes a little bit for everybody to catch up and get used to it,” said Price.

In a demonstration, Barry showed how the drone can bring a safety rope to a swimmer while rescuers prepare to pull the swimmer to shore.

“The speed and accuracy that this gives you … rapid deployment, speed, accuracy, and safety overall,” Price said. “Not just safety for the victim, but safety for our responders.”

Netflix teases its animated Splinter Cell series

It’s been quite some time since we heard anything about Netflix’s animated adaptation of Splinter Cell — but the streamer has finally provided some details on the show. The reveal comes in the form of a very brief teaser trailer, which shows a little bit of the show, but mostly showcases Liev Schreiber’s gravelly take on lead character Sam Fisher. We also have a proper name now: it’s called Splinter Cell: Deathwatch.

Correspondent Conor Knighton visits New Jersey beaches along the Delaware Bay to learn about horseshoe crabs – mysterious creatures that predate dinosaurs – whose very blood has proved vital to keeping humans healthy by helping detect bacterial endotoxins. He talks with environmentalists about the decline in the horseshoe crab population, and with researchers who are pushing the pharmaceutical industry to switch its use of horseshoe crab blood with a synthetic alternative used in medical testing.

SpaceX to launch bitcoin entrepreneur and three crewmates on flight around Earth’s poles

SpaceX to launch bitcoin entrepreneur and three crewmates on flight around Earth's poles


A blockchain entrepreneur, a cinematographer, a polar adventurer and a robotics researcher plan to fly around Earth’s poles aboard a SpaceX Crew Dragon capsule by the end of the year, becoming the first humans to observe the ice caps and extreme polar environments from orbit, SpaceX announced Monday.

The historic flight, launched from the Kennedy Space Center in Florida, will be commanded by Chun Wang, a wealthy bitcoin pioneer who founded f2pool and stakefish, “which are among the largest Bitcoin mining pools and Ethereum staking providers,” the crew’s website says.

“Wang aims to use the mission to highlight the crew’s explorational spirit, bring a sense of wonder and curiosity to the larger public and highlight how technology can help push the boundaries of exploration of Earth and through the mission’s research,” SpaceX said on its website.

Wang’s crewmates are Norwegian cinematographer Jannicke Mikkelsen, Australian adventurer Eric Philips and Rabea Rogge, a German robotics researcher. All four have an interest in extreme polar environments and plan to carry out related research and photography from orbit.

The mission, known as “Fram2” in honor of a Norwegian ship used to explore both the Arctic and Antarctic regions, will last three to five days and fly at altitudes between about 265 and 280 miles.

“This looks like a cool & well thought out mission. I wish the @framonauts the best on this epic exploration adventure!” tweeted Jared Isaacman, the billionaire philanthropist who charted the first private SpaceX mission — Inspiration4 — and who plans to blast off on a second flight — Polaris Dawn — later this month.

The flights “showcase what commercial missions can achieve thanks to @SpaceX’s reusability and NASA’s vision with the commercial crew program,” Isaacman said. “All just small steps towards unlocking the last great frontier.”

Like the Inspiration4 mission before them, Wang and his crewmates will fly in a Crew Dragon equipped with a transparent cupola giving them a picture-window view of Earth below and deep space beyond.

No astronauts or cosmonauts have ever viewed Earth from the vantage point of a polar orbit, one tilted, or inclined, 90 degrees to the equator. Such orbits are favored by spy satellites, weather stations and commercial photo-reconnaissance satellites because they fly over the entire planet as it rotates beneath them.

The high-inclination record for piloted flight was set in the early 1960s by Soviet Vostok spacecraft launched into orbits inclined 65 degrees. The U.S. record was set by a space shuttle mission launched in 1990 that carried out a classified military mission in an orbit tilted 62 degrees with respect to the equator.

The International Space Station never flies beyond 51.6 degrees north and south latitude. NASA planned to launch a space shuttle on a classified military mission around the poles in 1986, but the flight was canceled in the wake of the Challenger disaster.

“The North and South Poles are invisible to astronauts on the International Space Station, as well as to all previous human spaceflight missions except for the Apollo lunar missions but only from far away,” the Fram2 website says. “This new flight trajectory will unlock new possibilities for human spaceflight.”

SpaceX has launched 13 piloted missions carrying 50 astronauts, cosmonauts and private citizens to orbit in nine NASA flights to the space station, three commercial visits to the lab and the Inspiration4 mission chartered by Isaacman.

Isaacman and three crewmates plan to blast off Aug. 26 on another fully commercial flight, this one featuring the first civilian spacewalks. NASA plans to launch its next Crew Dragon flight to the space station around Sept. 24.

Finally, a screen that goes anywhere

Today we’re launching a totally new, totally different app. Meet Orion.

Orion is a small, fun app that helps you use your iPad as an external HDMI display for any camera, video game console, or even VHS. Just plug in one of the bajillion inexpensive adapters, and Orion handles the rest.

But wait — we’re a camera company. Why an HDMI monitor?

We built this to scratch a few itches. First, in professional cinematography, it’s common to connect an external screen to your camera to get a better view of the action. Orion not only gives you a bigger screen, but you can even share screenshots with your crew with a couple of taps.

We also built this for… pure fun. When traveling with a Nintendo Switch, it’s a delight to play games on a bigger screen, especially alongside friends.
