Young Mozambican inventor bringing the blind smart 'vision'
MATOLA, Mozambique: When Armando Ernesto Chau straps on the futuristic smart glasses that a young Mozambican robotics student is developing in the family dining room, he has a vision of a life less confined to his modest home. Chau is the prototype tester for Joao Antonio Rego, a 24-year-old robotics and electronic engineering student driven to provide visually impaired Mozambicans with assistance that goes beyond a simple cane. Since he lost his sight 20 years ago, the 45-year-old father has not worked and rarely leaves his home in Matola, outside the capital Maputo.
Rego's electronic glasses — battery-powered devices embedded with sensors that scan for obstacles ahead and emit warning vibrations — offer the promise of new possibilities. 'It is vibrating ... it is those bushes,' Chau said, demonstrating for AFP Rego's Vision Hope 0.2. 'Maybe, there is a window here... yes.' 'Because of these obstacles, it vibrates. So I go back,' he said. 'It stopped. See? Then it says there is something on this side... When I turn, it is quiet.'
Resembling a virtual reality eye mask, this is Rego's latest prototype since he launched his Vision Hope project in 2021, winning Mozambique's Young Creative Award for technological innovation the following year. New features include a larger 120-degree range and more accurate sensors, explained Rego, a student at Eduardo Mondlane University. The battery, attached to a strap that is worn over a shoulder, is on a smart system that saves power and warns when it is running low. A GPS allows others to know the whereabouts of the user.
Inspiration
Rego is already working on improvements in his dining room workshop. 'I want the next version to have sensors capable of detecting very thin obstacles like wires and threads,' he told AFP. 'The coating also needs to be waterproof,' he said. Slim and serious, Rego was inspired to help when, years ago, he saw a visually impaired woman fall in a busy street in downtown Maputo, said his mother, Helena Inacio.
'Seeing that woman on the ground disturbed him. He vowed that he would create glasses,' she told AFP. She had asked: ''Glasses for what? So that blind people can see?' He said, 'No, to give direction.'' 'I thought it was fantasy,' Inacio said. Rego moved his lab out of his bedroom for better ventilation after a health scare led a doctor to warn about the risks of fumes from his soldering work. 'I had health problems and after an X-ray, they said there were some spots on my lungs which might have been caused by chemical fumes, like tin. It was temporary, but I must always take precautions,' he said.
Rego's own vision is to secure partnerships that will allow him to one day produce and distribute his glasses across his impoverished country, where nearly 2.7 million people suffer vision loss, according to the International Agency for the Prevention of Blindness. Chau, who lost his sight after falling ill in 2005 and undergoing treatment in hospital, has made some suggestions for the next iteration. 'I told him to first improve the roadside verification system,' he said.
He would also like a sensor that can detect the pools of stagnant water that are common in his area. And, if possible, a way for detected obstacles to be identified. 'A system that communicates... about what kind of obstacle is in front of me, if it is a human being, a car,' he said. 'If the glasses are made the way I suggest, it will help us a lot, me and many other visually impaired people out there,' said Chau. — AFP
When they are in production and he can get his own pair, the glasses will give Chau a new lease of life, said his wife, Felizarda Nhampule. 'Sometimes he stays here at home alone while I go out and do my errands. Sometimes he wants to go out somewhere but can't,' she said. 'With the glasses, he will be able to visit his friends and get rid of the boredom of staying at home. In case of an emergency, he can go and seek help from neighbors,' she told AFP, flashing a smile. 'So these glasses will be a great help to him and to us as a family.'- AFP

France orders Tesla to end ‘deceptive practices'
France orders Tesla to end 'deceptive practices' PARIS: French anti-fraud authorities said on Tuesday they have ordered US electric car giant Tesla's local subsidiary to stop 'deceptive commercial practices' after an investigation found several violations harmful to consumers and contrary to law. The fraud prevention and consumer protection agency (DGCCRF) said its agents investigated Tesla's French subsidiary between 2023 and 2024 after reports were filed on a consumer complaint platform. The probe revealed 'deceptive commercial practices regarding the fully autonomous driving capabilities of Tesla vehicles, the availability of certain options and vehicle trade-in offers', it said. The agency also cited delays in refunding cancelled orders, a lack of information on the location of deliveries and incomplete sales contracts, among other violations. Tesla was given four months to comply with regulations. It faces a daily fine of 50,000 euros ($58,000) if it fails to stop deceptive commercial practices over the fully autonomous driving option of certain Tesla models. Tesla did not immediately respond to an AFP request for comment. Tesla sales have tanked in Europe in recent months owing to an ageing fleet of cars, rising competition and consumer distaste for Elon Musk's role in US President Donald Trump's administration. — AFP

‘Spectacular' Viking burial site discovered in Denmark
In an accidental find, a 10th-century burial site believed to have belonged to a Viking noble family has been discovered in northern Denmark, packed with a 'spectacular' trove of ancient objects, a museum announced Tuesday. The discovery came when pearls, coins, ceramics and a box containing a gold thread were unearthed during construction work near Lisbjerg, a village located seven kilometers (four miles) north of Aarhus, Denmark's second-largest city. Archaeologists found the site contained around 30 graves dating from the second half of the 10th century, when the famous King Harald Bluetooth reigned, said the Moesgaard Museum in Aarhus. According to the museum's archaeologist Mads Ravn, the graves are most likely linked to a noble family from the Viking Age -- which lasted between the eighth and 11th centuries -- whose farm was discovered less than a kilometer from the burial site in the late 1980s. Conservator Helle Strehle holds a Viking Age silver coin discovered at a Viking Age burial site. An aerial photo shows archaeologists working at a Viking Age burial site in Lisbjerg.

Archaeologists work at a Viking Age burial site in Lisbjerg. 'This could have been one of Harald Bluetooth's earls or stewards,' Ravn told AFP. Ravn noted that the king, who introduced Christianity to what is today Denmark, tasked nobles with managing certain regions. Researchers also discovered some human remains, such as teeth and bones, at the site. 'People basically took what was important to them into the grave because they wanted to transfer it to the other world,' the archaeologist said. One of the graves, which scientists believe belonged to an important woman, contained a box filled with decorative objects and a pair of scissors. The 'magnificent' box is a remarkable find, according to Ravn, with only a few having been discovered before, including one in southeastern Germany. 'It's very rare, there's only three of them we know of,' he said. The excavations at Lisbjerg are due to be completed this week, after which experts will begin a thorough analysis of the objects recovered. Wooden objects in particular should help them accurately date the burial site. As a royal and commercial center, Aarhus was one of Denmark's most important cities during the Viking Age.— AFP
