Newly found snake species in AlUla seen as symbol of Arabian Peninsula’s biodiversity

CHICAGO: Working as a teacher with members of the deaf and hard-of-hearing community helped a Saudi artificial intelligence scholar realize that technology held the potential to help improve the way they communicate with the world.

After working with people with hearing impairments for more than a decade-and-a-half, Bader Alsharif said he has come to understand that one of the greatest challenges they face is the public’s lack of understanding of sign language. He realized that if this barrier could be overcome, it would not only improve this community’s ability to communicate but also help the wider public better understand the lives of those who rely on signing.

“I decided to focus on sign language and AI because of my close work with students over the past 16 years,” the 39-year-old told Arab News. “I saw the challenges they face when it comes to communication, especially in situations where people around them don’t understand sign language.

“That really touched me and made me want to help. So, using my background in computer engineering and the power of artificial intelligence, I realized we could create a smart system that recognizes sign language in real time and translates it into words.

“This can help bridge the gap between the deaf and hearing community. In simple terms, a camera captures the person making a hand gesture and then AI models analyze those gestures using deep learning and hand tracking. Then the system matches the gesture to letters and words, and displays the meaning of the particular words.”

As Alsharif became more immersed in his academic research, he quickly identified the potential for AI to be a transformative tool in support of deaf students. He personally understands about 30 percent of sign language gestures but the AI-powered program he is developing is designed to interpret the full range of signs, which would help to bridge the communication gap.

The computer engineering scholar has spent several months working with a team to build a dataset that includes every aspect of each sign language gesture and its English translation. The dataset contains nearly 130,000 images of hand gestures, each of which is assigned 21 data points to help the system correctly identify and translate the sign.

Though the initial version is for English translation, Alsharif said datasets can be created for all languages, and his next goal is to create a version that interprets Saudi Sign Language.

“As soon as we have a good dataset, we can implement any sign language translation system into any language,” he added.

Right now, the system is one-way, translating sign language into English, with some limitations. The next challenge, he said, is to reverse the process and expand the system to translate speech, in any language, into sign language.

Originally from Makkah, Alsharif graduated with bachelor’s degree from the College of Technology in Riyadh in 2008 and began working for the Technical and Vocational Training Corporation in Riyadh. In 2017 he received a master’s degree in computer engineering from the Florida Institute of Technology.

His work aims to combine technological innovation with social impact, a goal that positions him as a forward-thinking leader in the use of computer engineering in healthcare.

Alsharif has been studying for a doctorate since 2021 at Florida Atlantic University, where his research focuses on various aspects of sign language-recognition systems, and the use of AI and the internet in the provision of medical services.

He also works as a teaching assistant, guiding and evaluating more than 30 students who are carrying out engineering-design projects. He also assists more than 200 students with advice about technical questions, design principles and project development.

“All these studies use artificial intelligence to help solve real-world problems and support people who have special needs,” Alsharif said.

Alsharif, who lives in Boca Raton, Florida, with his wife and four children, said he is grateful to the government of Saudi Arabia, which made all of his achievements possible. Other innovative projects he has led or been involved with include the opening of digital communications technology company CISCO’s first office in Saudi Arabia, and he has has managed the optimization of performance and security for more than 300 devices.

He has also published more than 10 peer-reviewed papers, with a focus on AI, cybersecurity and the Internet of Things, particularly as they relate to healthcare. He says he has a particular commitment to advancing technology and fostering inclusivity, particularly through his work with individuals with special needs.

MANCHESTER: Manchester United came from 4-2 down in extra-time to beat Lyon 5-4 in a remarkable Europa League quarter-final to progress 7-6 on aggregate on Thursday.
United’s season looked over when Lyon came from 2-0 down to lead by two goals with just six minutes remaining at Old Trafford despite having captain Corentin Tolisso sent-off.
However, a Bruno Fernandes’ penalty, Kobbie Mainoo’s strike and Harry Maguire’s header capped a stunning finale to set up a semifinal meeting with Athletic Bilbao.
The Red Devils sit 14th in the English top flight and defeat would have almost certainly meant missing out on European football entirely next season.
Instead they are just three games away from a European trophy and the lifeline of direct access to the riches of the Champions League next season.
First-half goals from Manuel Ugarte and Diogo Dalot had put United in a commanding position.
But the defensive deficiencies and mental fragility of Ruben Amorim’s side were exposed in a collapse that threatened to cap a miserable campaign.
Two goals in seven minutes from Corentin Tolisso and Nicolas Tagliafico brought Lyon level.
Tolisso was then sent-off for two yellow cards in the 89th minute.
The 10 men still looked set to prevail in the extra 30 minutes thanks to a brilliant strike from Rayan Cherki and Alexandre Lacazette’s penalty.
United’s history is build on dramatic late fightbacks but few have been more remarkable than this to leave Lyon shellshocked.
The home side got off to a flying start thanks to a fine team goal as Fernandes released Alejandro Garnacho down the right and his cross picked out Ugarte to slot in just his second goal since joining the English giants form Paris Saint-Germain.
Amorim’s decision to restore Andre Onana in goal was under scrutiny.
The Cameroonian had been dropped for Sunday’s 4-1 thrashing at Newcastle after two costly errors that led to both Lyon’s goals in last week’s 2-2 first leg draw.
Those mistakes came after a war of words with former United midfielder Nemanja Matic, who labelled him “one of the worst goalkeepers in United’s history.”
The 29-year-old rewarded his manager’s faith with a couple of important stops to prevent Lyon levelling through Paul Akouokou and Cherki.
At the other end, a United side that have often looked labored and lacking in ideas all season, suddenly clicked into gear in the first 45 minutes.
United doubled their lead in first-half stoppage time when Maguire’s long ball was expertly controlled by Dalot, who then fired in off the inside of the post.
Garnacho should have killed the tie off within minutes of the restart for the second half when he shot straight at Lucas Perri with Fernandes begging for a pass for a tap in.
That was to prove a turning point as United crumbled in stunning fashion.
Lyon boss Paulo Fonseca was able to prowl the touchline unlike in Ligue 1 where he is serving a nine-month touchline ban.
The Portuguese introduced captain Lacazette off the bench in a bid to turn the tide.
And the former Arsenal striker played a central role in the fightback.
Lacazette flicked on Moussa Niakhate’s header and Tolisso swooped to head in and give the visitors a lifeline.
Tagliafico then prodded in at the back post despite Onana’s attempt to scoop it off the line.
Just as Lyon were in the ascendency Tolisso gave them a mountain to climb again with a soft second yellow for a trip on Casemiro.
Yet, it did not initially matter as Cherki confirmed his status as one of Europe’s rising stars with a powerful drive that left Onana motionless.
Lyon’s other prized asset Malick Fofana was then chopped down by Luke Shaw inside the area and Lacazette confidently dispatched the resulting spot-kick.
Another penalty at the other end, though, kickstarted the fightback as Fernandes fired home.
Substitute Mainoo showed why he had been thrust in an unfamiliar forward role with a composed finish to level on 120 minutes.
Barely 60 seconds later Maguire completed the comeback with a towering header at the back post.
