Greek researchers enlist EU satellite against Aegean sea litter

  • “All the targets were carried into the sea, the satellites passed by and we’re ready to fill out the first report”
  • Satellite data is provided free from the European Space Agency (ESA) and hours after the overpass targets should be detected from the Sentinel-2 satellite

LESBOS ISLAND, Greece: Knee-deep in water on a picture-postcard Lesbos island beach, a team of Greek university students gently deposits a wall-sized PVC frame on the surface before divers moor it at sea.
Holding in plastic bags and bottles, four of the 5 meter-by-5-meter (16 foot-by-16-foot) frames are part of an experiment to determine if seaborne litter can be detected with EU satellites and drones.
“This was the first big day,” says project supervisor Konstantinos Topuzelis, an assistant professor at the University of the Aegean department of Marine Sciences, said of the scene from last week.
“All the targets were carried into the sea, the satellites passed by and we’re ready to fill out the first report.”
The results of the experiment — “Satellite Testing and Drone Mapping for Marine Plastics on the Aegean Sea” — by the university’s Marine Remote Sensing Group will be presented at a European Space Agency symposium in Milan in May.
“Marine litter is a global problem that affects all the oceans of the world,” Topouzelis told AFP.
Millions of tons of plastic end up in the oceans, affecting marine wildlife all along the food chain.
“Modern techniques are necessary to detect and quantify marine plastics in seawater,” Topouzelis added, noting that space agencies have already been looking into how drones and satellites can help with the clean-up.
“The main advantage is that we are using existing tools,” which brings down costs and makes it easier to scale up, says Dimitris Papageorgiou, one of the 60 undergraduate and postgraduate students who worked on the experiment.
To prepare, the team gathered some 2,000 plastic bottles and lashed them to the frames. Other targets were crafted with plastic bags, as these are even harder to spot in the water and usually constitute the deadliest threat to Aegean marine life such as dolphins, turtles and seals.
In 2018, a first phase in the experiment was able to detect large targets of around 100 square meters from space.
This year’s experiment uses targets a quarter that size to test the smallest detectable area under various weather conditions.
“It was a crazy idea,” laughs Topouzelis.
“We knew that the European satellite system passes at regular intervals with a spatial resolution of 10 meters.”
In theory, then, the satellites should be able to detect the floating rafts of plastic the team pushed out to sea.
The University of the Aegean is working on the project with Universidad de Cadiz in Spain, CNR-Ismar in Italy and UK environmental consultants Argans Ltd.
Satellite data is provided free from the European Space Agency (ESA) and hours after the overpass targets should be detected from the Sentinel-2 satellite.
The project acts as a calibration and validation exercise on the detection capabilities of the satellites.
But even if relatively small patches of plastic garbage can be spotted from orbiting satellites, the problem of how to remove it from the sea remains.
Last year, a giant floating barrier five years in the making was launched off the coast of San Francisco, as part of a $20-million project to clean up a swirling island of rubbish between California and Hawaii.
But the slow speed of the solar-powered barrier prevents it from holding onto the plastic after it scoops it up.


Saudi ‘smart glove’ inventor thrives in the age of innovation

Saudi ‘smart glove’ inventor thrives in the age of innovation

  • Hadeel Ayoub is the founder of BrightSign, a London-based company specializing in assistive technology
  • BrightSign's signature product is a smart glove that can facilitate communication by individuals with speech disability

LONDON: Saudi inventor and tech innovator Hadeel Ayoub is giving people who can’t speak new hope — and a new voice.

The founder of London-based tech company BrightSign is the driving force behind a smart glove that allows individuals who are unable to speak to communicate by translating sign language into text and speech.

After more than four years’ work, Ayoub, a designer, programmer and researcher in human computer interaction, plans to launch the device later this year.

Some of the biggest beneficiaries will be families with children who have speech disabilities and want to be better connected through technology. The BrightSign glove will enable these children to become better signers and communicators, but can also be hooked up with a web app to provide instant translation in most languages.

The architecture of a BrightSign glove is relatively straightforward: Multiple sensors, embedded under an outer glove, track finger positions, hand orientation and dynamic movements. The hardware is contained inside a slender wristband.

Hand gestures are translated into text that appears on a screen embedded in the glove, and speech is made audible via a mini-speaker. The user can select the voice and speech language.


BIO

• Founder and chieftechnology officer, BrightSign

• Experienced lecturer, researcher and entrepreneur with experience in the higher education industry

• Skilled in innovation, creative coding, programming and design research

• Ph.D. in human-computer interaction and gesture recognition from Goldsmiths, University of London


Ayoub has been featured in Forbes magazine, tech programs on the BBC and Discovery channels, and has spoken at discussions organized by Britain’s Financial Times and Guardian newspapers. She has also taken part in a number of exhibitions with innovation and assistive technology as their themes.

Recalling the inspiration for the smart glove, the Saudi inventor said she was originally designing a device for an air-draw program — the air was the canvas, and the hands and fingers were the drawing tools. Her aim was to replace the mouse and keyboard with trackable wearable technology.

On the basis of her design, Ayoub was selected to represent her university at an IBM global hackathon in artificial intelligence for social care. She reprogrammed the glove to translate sign language and won the competition.

When news of the smart glove was circulated in the media, Ayoub’s inbox was flooded with inquiriesttt from parents wanting the glove for their children, from speech therapists for their patients, and from teachers for their students.

The tech innovator quickly realized there was a need for this kind of technology and decided to make it the focus of her Ph.D. research.

“I want to break the current barriers facing those who wish to broaden their experience with sign language beyond the current traditional method,” Ayoub said.

She believes that at least three improvements are urgently needed: Integrating children with disabilities into mainstream classrooms; equipping adults who have disabilities with technologies that will help them perform tasks as well as their peers manage; and making smart-glove devices available in public locations such as airports, shopping malls, government offices and hospitals to offer a smoother service to visitors with disabilities.

A global award winner for her technological innovation, Ayoub regularly tests and improves the BrightSign glove, which she describes as a work in progress.

“The glove has gone through multiple rounds of prototyping and testing. I have implanted the users’ feedback to develop hardware, software and design,” she said.

“It is now being used in six schools to help non-verbal children overcome their communication challenges in the classroom.”

Ayoub said that further studies would help her develop the final product. “I am now taking glove pre-orders on the BrightSign website,” she said.

The Saudi inventor said that she has always been “a progressive thinker and a dreamer of possibilities,” and described a childhood spent immersed in books rather than playing with dolls.

She remembers her family library with fondness and reminisces on quiet evenings spend reading.

As well as being an innovator, Ayoub is a mother who talks lovingly about her children.

“They are very much involved in the development phases of BrightSign,” she said. “I consider their opinions on the products designed for children. I always encourage them to do what they love since that would mean that they will excel in it.

“They get excited every time they see someone using BrightSign and they can see how it helps people live better.

“They also understand the concept of tech for good and aspire to work one day on technologies with a social impact.”

Ayoub sees herself as problem solver with an eye for technical detail, a kind of instinctive trouble-shooter. “When I attempt to solve a problem, I go through cycles of trial and error until I achieve a breakthrough,” she said.

“I encountered a number of problems that were unprecedented, so I wasn’t able to turn to a source or a reference. I guess this is what prompted me to get creative and think outside the box, which eventually put me on the innovation route.

“I find dead ends challenging. When someone tells me that something has never been done, it does not mean that it is not doable. On the contrary, it motivates me to keep going until I find a solution.”

As for the current model of innovation, Ayoub admires the global interconnectedness.

“The mindset now is collaborative rather than competitive,” Ayoub said.

“I am part of inventors’ groups in Saudi Arabia, the Gulf region and the Middle East. Most of us got business training at some point in order to secure investment and go into production.”

I find dead ends challenging. It motivates me to keep going to find a solution.

Hadeel Ayoub

Being a innovator has been far from a walk in the park for Ayoub. She believes what really pushed her in her chosen field was her desire to learn something new in every degree she pursued, starting with design, then programming and, finally, technology.

“More often than not I find myself the only woman speaking at a tech conference or giving a tech talk at an event,” she said. “I am proud to represent my country in global exhibitions and am even prouder when I walk away with awards at competitions.

“I hope that I can inspire young girls to experiment with technology and use it to enhance their respective practices.

“I have created a ‘women in tech’ group where we have regular meetings to share our challenges and extend our support each other.”

Based on her experiences, Ayoub has a message for young Saudis: “This is the age of innovation and entrepreneurship. If what you are passionate about doesn’t exist as a field of knowledge, create it.

“Learn how to code. It will be useful in any career you pursue and will enable you to integrate technology into your practice.”
