Landmarks for vision systems, LiDAR, and the IMU were evaluated. To solve the identified problems, the researchers suggest radio-frequency-based localization as a potential solution for practical augmented reality applications. Facebook Twitter Pinterest LinkedIN Email Smartphone-based augmented reality, in which visual elements are overlaid on the image of a smartphone camera, are extremely popular apps. These apps allow users to see how furniture would look in their house, or navigate maps better, or to play interactive games. The global phenomenon Pokémon GO, which encourages players to catch digital creatures through their phone, is a well-known example. However, if you want to use augmented reality apps inside a building, prepare to lower your expectations. The technologies available now to implement augmented reality struggle when they can't access a clear GPS signal. But after a series of extensive and careful experiments with smartphones and users, researchers from Osaka University have determined the reasons for these problems in detail and identified a potential solution. The work was recently presented at the 30th Annual International Conference on Mobile Computing and Networking. "To augment reality, the smartphone needs to know two things," says Shunpei Yamaguchi, the lead author of the study. "Namely, where it is, which is called localization, and how it is moving, which is called tracking." To do this, the smartphone uses two main systems: visual sensors (the camera and LiDAR) to find landmarks such as QR codes or AprilTags in the environment, and its inertial measurement unit (IMU), a small sensor inside the phone that measures movement. To understand exactly how these systems perform, the research team set up case studies such as a virtual classroom in an empty lecture hall and asked participants to arrange virtual desks and chairs in an optimal way. Overall, 113 hours of experiments and case studies across 316 patterns in a real-world environment were performed. The aim was to isolate and examine the failure modes of AR by disabling some sensors and changing the environment and lighting. "We found that the virtual elements tend to 'drift' in the scene, which can lead to motion sickness and reduce the sense of reality," explains Shunsuke Saruwatari, the senior author of the study. The findings highlighted that visual landmarks can be difficult to find from far away, at extreme angles, or in dark rooms; that LiDAR doesn't always work well; and that the IMU has errors at high and low speeds that add up over time. To address these issues, the team recommends radio-frequency-based localization, such as ultra-wideband (UWB)-based sensing, as a potential solution. UWB works similarly to WiFi or Bluetooth, and its most well-known applications are the Apple AirTag and Galaxy SmartTag+. Radio-frequency localization is less affected by lighting, distance, or line of sight, avoiding the difficulties with vision-based QR codes or AprilTag landmarks. In the future, the researchers believe that UWB or alternative sensing modalities like ultra-sound, WiFi, BLE, or RFID have the potential for integration with vision-based techniques, leading to vastly improved augmented reality applications.

Google and the US government faced off in a federal court on Monday, as each side delivered closing arguments in a case revolving around the technology giant's alleged unfair domination of online advertising. The trial in a Virginia federal court is Google's second US antitrust case now under way as the US government tries to rein in the power of big tech. In a separate trial, a Washington judge ruled that Google's search business is an illegal monopoly, and the US Justice Department is asking that Google sell its Chrome browser business to resolve the case. The latest case, also brought by the Justice Department, focuses on ad technology for the open web -- the complex system determining which online ads people see when they surf the internet. The vast majority of websites use a trio of Google ad software products that together, leave no way for publishers to escape Google's advertising technology, the plaintiffs allege. Publishers -- including News Corp and Gannett publishing -- complain that they are locked into Google's advertising technology in order to run ads on their websites. "Google is once, twice, three times a monopolist," DOJ lawyer Aaron Teitelbaum told the court in closing arguments. Presiding judge Leonie Brinkema has said that she would deliver her opinion swiftly, as early as next month. Whatever Brinkema's judgment, the outcome will almost certainly be appealed, prolonging a process that could go all the way to the US Supreme Court. The government alleges that Google controls the auction-style system that advertisers use to purchase advertising space online. The US lawyers argue that this approach allows Google to charge higher prices to advertisers while sending less revenue to publishers such as news websites, many of which are struggling to stay in business. The US argues that Google used its financial power to acquire potential rivals and corner the ad tech market, leaving advertisers and publishers with no choice but to use its technology. The government wants Google to divest parts of its ad tech business. Google dismissed the allegations as an attempt by the government to pick "winners and losers" in a diverse market. The company argues that the display ads at issue are just a small share of today's ad tech business. Google says the plaintiffs' definition of the market ignores ads that are also placed in search results, apps and social media platforms and where, taken as a whole, Google does not dominate. "The law simply does not support what the plaintiffs are arguing in this case," said Google's lawyer Karen Dunn. She warned that if Google were to lose the case, the winners would be rival tech giants such as Microsoft, Meta or Amazon, whose market share in online advertising is ascendant as Google's share is falling. The DOJ countered that it simply "does not matter" that Google is competing in the broader market for online ads. "That is a different question" than the market for ads on websites that is the target of the case, said Teitelbaum. Google also points to US legal precedent, saying arguments similar to the government's have been refuted in previous antitrust cases. Dunn also warned that forcing Google to work with rivals in its ad products would amount to government central planning that the court should reject. If the judge finds Google to be at fault, a new phase of the trial would decide how the company should comply with that conclusion. And all that could be moot if the incoming Trump administration decides to drop the case. The president-elect has been a critic of Google's, but he warned earlier this month that breaking it up could be "a very dangerous thing." arp/dw
One of the key areas that artificial intelligence (AI) threatens to disrupt is human creativity — and the rise of generative AI has certainly thrown art into the spotlight. While fears remain that AI may replace human input and agency across society, a different approach suggests humans will meld with AI in some capacity — with the new technologies augmenting us rather than undermining us. In " Centaur Art: The Future of Art in the Age of Generative AI " (Springer, 2024), computer scientist Remo Pareschi explores the notion of "centauric intelligence" — an integration of human and computing intelligence — and its impact on the future of art. In this excerpt, Pareschi explains how our primal fears are misguided and argues that the rise of AI may, in fact, help human creative endeavors transcend to new heights. As we revisit our initial, most pressing concern — will artificial intelligence surpass human creativity in artistic endeavors? — it's crucial to recognize that the question, as commonly posed, is somewhat misdirected. Unlike games such as chess or Go, art cannot be measured by a simple win-lose metric. The fear, however, is similar: could humans be supplanted in artistic production as they have been in high-level chess? Our analysis, grounded in cognitive considerations and carried out in the pages to come, suggests a nuanced answer. At the pinnacle of creativity — where inspiration, conception and originality reign — AI is an enhancer, aiding in realizing powerful and original works. In such contexts, the human artist's role remains paramount, with AI serving as a tool to augment their creative vision. Conversely, AI's role can become more structured or repetitive. It can automate the production of routine outputs such as certain types of commercial illustrations, brochures, or video game characters. This automation significantly impacts professionals in these fields, who may rely on such work for their livelihood. Consequently, these individuals may... Remo Pareschi
San Rafael Schools to Form AI Committee for RecommendationsWashington, Nov 23 (AP) Scott Turner, President-elect Donald Trump choice to lead the Department of Housing and Urban Development, is a former NFL player who ran the White House Opportunity and Revitalisation Council during Trump's first term. Turner, 52, is the first Black person selected to be a member of the Republican's Cabinet.

From professional football to politics Turner grew up in a Dallas suburb, Richardson, and graduated from the University of Illinois Urbana-Champaign. He was a defensive back and spent nine seasons in the NFL beginning in 1995, playing for the Washington Redskins, San Diego Chargers and Denver Broncos. During offseasons, he worked as an intern then-Rep. Duncan Hunter, R-Calif. After Turner retired in 2004, he worked full time for the congressman. In 2006, Turner ran unsuccessfully as a Republican in California's 50th Congressional District. Turner joined the Texas House in 2013 as part of a large crop of tea party-supported lawmakers. He tried unsuccessfully to become speaker before he finished his second term in 2016. He did not seek a third term. Motivational speaker and pastor Turner also worked for a software company in a position called “chief inspiration officer” and said he acted as a professional mentor, pastor, and councilor for the employees and executive team. He has also been a motivational speaker. He and his wife, Robin Turner, founded a nonprofit promoting initiatives to improve childhood literacy. His church, Prestonwood Baptist Church, lists him as an associate pastor. He is also chair of the centre for education opportunity at America First Policy Institute, a think tank set up by former Trump administration staffers to lay the groundwork if he won a second term. Headed council in Trump's first term Trump introduced Turner in April 2019 as the head of the new White House Opportunity and Revitalisation Council. Trump credited Turner with “helping to lead an Unprecedented Effort that Transformed our Country's most distressed communities”. The mission of the council was to coordinate with various federal agencies to attract investment to so-called “Opportunity Zones", which were economically depressed areas eligible to be used for the federal tax incentives. The role of HUD HUD is responsible for addressing the nation's housing needs. It also is charged with fair housing laws and oversees housing for the poorest Americans, sheltering more than 4.3 million low-income families through public housing, rental subsidy and voucher programmes. The agency, with a budget of tens of billions of dollars, runs a multitude of programs that do everything from reducing homelessness to promoting homeownership. It also funds the construction of affordable housing and provides vouchers that allow low income families pay for housing in the private market. During the campaign, Trump focused mostly on the prices of housing, not public housing. He railed against the high cost of housing and said he could make it more affordable by cracking down on illegal immigration and reducing inflation. He also said he would work to reduce regulations on home construction and make some federal land available for residential construction.
