RFL Group's electronics brand Vision has brought OLED TV to the local market. RN Paul, managing director of RFL Group, unveiled the cover of VISION OLED TV at a programme at a hotel in the capital recently. "Compared to LCD and LED TVs, OLED TVs have several benefits. The crystalline layers in OLED TVs are thinner, lighter and more flexible than those in LED or LCD TVs. This allows significantly broader viewing angles and is ideal for situations when many people watch TV at once." Shaikh Mahabubur Rahman, head of marketing at Vision Electronics, said, "Vision OLED TV comes with 4.8mm thickness and 4K resolution. It has a Chameleon process engine, and a 120Hz refresh rate which is required for perfect picture and gaming."

World's largest and most influential tech event Consumer Electronics Show (CES) 2023 is going on in the USA's Las Vegas. CES is a global platform where the tech giants exhibit the latest innovation in consumer technology, the automotive industry and digital healthcare. AI, smart health, driverless cars, smart homes and the metaverse have been the centre of attractions for visitors, entrepreneurs and suppliers of technology products at this year's CES. The metaverse is a big theme at CES 2023. Many companies have unveiled their latest offerings in virtual reality and augmented reality. There are many unusual inventions on display, from a speech privacy mask to smart golfing tools, a smart punching bag cover and even electric inline skates. One start-up, OVR Technology, is presenting a headset that allows users to smell in the metaverse. The device could have applications beyond gaming, for example in health and wellness. A part of the show floor has been dedicated to Web3 technology. Also, Microsoft and the carmaker Stellantis have teamed up to create a showroom in the metaverse.

"We have already finalised a business deal with one of the largest online marketplaces in America. Through this marketplace, Walton products will be available for sale in the American market from February or March this year." The four-day fair will draw to a close Sunday.  

Ask the new artificial intelligence tool ChatGPT to write an essay about the cause of the American Civil War and you can watch it churn out a persuasive term paper in a matter of seconds. That’s one reason why New York City school officials this week started blocking the impressive but controversial writing tool that can generate paragraphs of human-like text. The decision by the largest U.S. school district to restrict the ChatGPT website on school devices and networks could have ripple effects on other schools, and teachers scrambling to figure out how to prevent cheating. The creators of ChatGPT say they’re also looking for ways to detect misuse. The free tool has been around for just five weeks but is already raising tough questions about the future of AI in education, the tech industry and a host of professions. WHAT IS CHATGPT? ChatGPT launched on Nov. 30 but is part of a broader set of technologies developed by the San Francisco-based startup OpenAI, which has a close relationship with Microsoft. It’s part of a new generation of AI systems that can converse, generate readable text on demand and even produce novel images and video based on what they’ve learned from a vast database of digital books, online writings and other media. But unlike previous iterations of so-called “large language models,” such as OpenAI’s GPT-3, launched in 2020, the ChatGPT tool is available for free to anyone with an internet connection and designed to be more user-friendly. It works like a written dialogue between the AI system and the person asking it questions. Millions of people have played with it over the past month, using it to write silly poems or songs, to try to trick it into making mistakes, or for more practical purposes such as helping compose an email. All of those queries are also helping it get smarter. WHAT ARE THE PITFALLS? As with similar systems, ChatGPT can generate convincing prose, but that doesn’t mean what it says is factual or logical. Its launch came with little guidance for how to use it, other than a promise that ChatGPT will admit when it’s wrong, challenge “incorrect premises” and reject requests meant to generate offensive answers. Since then, however, its popularity has led its creators to try to lower some people’s expectations. “ChatGPT is incredibly limited, but good enough at some things to create a misleading impression of greatness,” OpenAI CEO Sam Altman said on Twitter in December. Altman added that “it’s a mistake to be relying on it for anything important right now.” “It’s a preview of progress; we have lots of work to do on robustness and truthfulness.” CAN IT BE USED FOR WRITING SCHOOL PAPERS? This is what ChatGPT said when The Associated Press asked it to answer that question in all caps from the perspective of a principal shouting a brief message through a school’s PA system: “DO NOT USE CHATGPT OR ANY OTHER AUTOMATED WRITING TOOL FOR SCHOOL PAPERS. THIS IS CHEATING AND WILL NOT BE TOLERATED. IF YOU ARE CAUGHT USING CHATGPT OR ANY OTHER AUTOMATED WRITING TOOL FOR SCHOOL PAPERS, THERE WILL BE SERIOUS CONSEQUENCES.” But when asked to answer the same question on its own, ChatGPT offered this more measured warning: “As a general rule, it is not appropriate to use ChatGPT or any other automated writing tool for school papers, as it is considered cheating and does not benefit the student in the long run.” WHAT DO SCHOOLS SAY? Many school districts are still scrambling to figure out how to set policies on if and how it can be used. The New York City education department said Thursday that it’s restricting access on school networks and devices because it’s worried about negative impacts on student learning, as well as “concerns regarding the safety and accuracy of content.” But there’s no stopping a student from accessing ChatGPT from a personal phone or computer at home. “While the tool may be able to provide quick and easy answers to questions, it does not build critical-thinking and problem-solving skills, which are essential for academic and lifelong success,” said schools spokesperson Jenna Lyle. HUMAN OR AI? “To determine if something was written by a human or an AI, you can look for the absence of personal experiences or emotions, check for inconsistency in writing style, and watch for the use of filler words or repetitive phrases. These may be signs that the text was generated by an AI.” That’s what ChatGPT told an AP reporter when asked how to tell the difference. OpenAI said in a human-written statement this week that it plans to work with educators as it learns from how people are experimenting with ChatGPT in the real world. “We don’t want ChatGPT to be used for misleading purposes in schools or anywhere else, so we’re already developing mitigations to help anyone identify text generated by that system,” the company said. DOES THIS THREATEN GOOGLE? There’s been some speculation that ChatGPT could upend the internet search business now dominated by Google, but the tech giant has been working on similar technology for years — it’s just more cautious about releasing it in the wild. It was Google that helped jumpstart the trend for ever-bigger, ever-smarter AI language models that could be “pre-trained” on a wide body of writings. In 2018 the company introduced a system known as BERT that uses a “transformer” technique that compares words across a sentence to predict meaning and context. Some of those advances are now baked into Google searches. But there’s no question that successive iterations of GPT — which stands for Generative Pre-trained Transformer — are having an impact. Microsoft has invested at least $1 billion in OpenAI and has an exclusive license to use GPT-3. HEY CHATGPT, CAN YOU PUT ALL THIS IN A RAP? “ChatGPT’s just a tool, But it ain’t no substitute for school. You can’t cheat your way to the top, Using a machine to do your homework, you’ll flop. Plagiarism’s a no-no, And ChatGPT’s text is not your own, yo. So put in the work, earn that grade, Don’t try to cheat, it’s not worth the trade.”

A 38-year-old retired NASA satellite is about to fall from the sky. NASA said Friday the chance of wreckage falling on anybody is “very low.” Most of the 5,400-pound (2,450-kilogram) satellite will burn up upon reentry, according to NASA. But some pieces are expected to survive. The space agency put the odds of injury from falling debris at about 1-in-9,400. The science satellite is expected to come down Sunday night, give or take 17 hours, according to the Defense Department.

Although its expected working lifetime was two years, the satellite kept making ozone and other atmospheric measurements until its retirement in 2005. The satellite studied how Earth absorbed and radiated energy from the sun. The satellite got a special sendoff from Challenger. America's first woman in space, Sally Ride, released the satellite into orbit using the shuttle's robot arm. That same mission also featured the first spacewalk by a U.S. woman: Kathryn Sullivan. It was the first time two female astronauts flew in space together.

More than a thousand startups are showcasing their products at the annual CES tech show in Las Vegas, hoping to create some buzz around their gadgets and capture the eyes of investors who can help their businesses grow. But amid the slew of layoffs in the tech industry and an economic landscape battered with high inflation and interest rates, many may be met with cautious investors looking for products that can deliver quick returns instead of hype. Analysts say the event this year has somewhat of a muted tone compared to prior shows, when many companies routinely unveiled pie-in-the-sky projects that never saw the light of day. Carolina Milanesi, president and principal analyst at the consumer tech research firm Creative Strategies, said this time around, many of the tech items displayed during the show’s media preview days, which occurred Tuesday and Wednesday, have been less “flamboyant” compared to prior years, which showcased things like talking microwaves and smart jeans that vibrate to direct users. “The economy — and I think the mood in general — is a little bit negative around tech,” Milanesi said. “It’s really getting companies to focus on real value for customers.“ CES, the most influential tech gathering in the world, officially begins on Thursday to attendees in the industry. Roughly 3,000 companies have registered to attend the event, including big companies like Amazon that are laying off thousands of employees and axing unprofitable areas of their business amid uncertainty in the wider economy. Simultaneously, many startups are attempting to find their wings at a time when consumers are tightening their belts and being more picky about how to spend their money. And experts note the somber economic climate can be particularly difficult for companies who make hardware products — they typically require robust investments to manufacture their gadgets and often encounter challenges with securing the money they need. Marco Snikkers, founder and CEO of OneThird, a startup that tests produce ripeness, said investors have been much more critical this year about which companies to fund. Securing investments for his own company took much longer than anticipated but luckily, he said, some existing investors stepped up to help and the company didn’t run out of cash. They were able to secure more funding last month. “We can hopefully survive 2023 with what we have today,” Snikkers said, adding the Netherlands-based company, which also has an app, hopes to expand their products to the U.S. Another CES attendee, Mohamed Soliman, founder of the French electric skates startup AtmosGear, said investors have been more fearful about putting money into projects during the entire pandemic and are asking for a higher level of maturity from companies before they put some skin in the game. “I think CES could be a ‘do or die’ time for many startups,” said Wedbush analyst Dan Ives. “The clock struck midnight in terms of tech investors just giving away free money. There’s a lot more competing for capital.” Saving money has now become a big priority for the tech industry, a shift from the past when more analysts and investors were more focused on how companies were growing. Ives said unlike products that received a lot of buzz during prior shows but didn’t have a clear revenue path, like drones, investors are now looking to fund things that can be deployed, such as artificial intelligence, chip technology and electric vehicles. More transformational tech themes, such as broader use of virtual reality and immersive experiences in the metaverse, are also being showcased at the show. Though the metaverse has its skeptics, Ives said he believes all these technologies could lay the groundwork for what’s likely to be a fourth industrial revolution. But as of now, a recession is potentially on the doorstep, he said. “And I think that’s the elephant in the room at this year’s CES.” Event organizers for their part say excitement hasn’t dampened. Brian Comiskey, the director of thematic programs at the Consumer Technology Association, the trade group putting together the show, said many startups are excited to be back at the event and mingle in person with investors after COVID kept many of them away for the past two shows. The organization also has a program, called CTA Match, that pairs startups with investors who might be interested in their products, he said, adding many companies have showcased items that can be rolled out soon, or are innovations that could be deployed if they meet the right investors. But even entrepreneurs that raise money are facing higher costs due to inflation. That, coupled with a more challenging investment scene could mean more companies won’t be able to make it — or won’t be able to make it with the cash they have on hand, a scenario that could lead to more mergers with big companies, said Peter Csathy, chairman of the media and tech advisory firm Creative Media. Still, startups are trying to get the most out of the show and will attempt to create buzz around their products in an effort to grab some headlines and get free marketing, Csathy said.

CES is not allowing Russian companies to display their gadgets at the annual tech show because of the country’s invasion of Ukraine. A spokesperson for the Consumer Technology Association, the trade group putting together the event in Las Vegas, said the move has only impacted one potential exhibitor. The organization did not immediately respond to an inquiry about how many Russian companies attended past CES events, or if there was less interest from them this year. The U.S. is among about 30 countries that have sanctioned Russia over the invasion. Read more: Best of CES 2023: Electric skates, pet tech and AI for birds CTA president and CEO Gary Shapiro, who previously called the Russian invasion a “tragic and illegal assault on the people and independent nation of Ukraine,” said some Ukrainian tech companies and startups will display their gadgets at the Las Vegas show. “A lot of people from around the world want to support Ukraine,” Shapiro said in an interview, while wearing a Ukrainian flag pin on his jacket lapel. “I know my wife actively seeks out products from Ukraine that she can order. And we have bought stuff from Ukraine directly.” The tech show is expected to draw up to 100,000 attendees by the time it concludes on Sunday. It kicked off on Tuesday evening with media previews from just some of the 3,000 companies signed up to attend. CES officially opens Thursday. It’s open to the media and others in the tech industry, but not the general public.
