| Posted: 21 Jun 2022 04:29 AM PDT  Signify has announced a wide array of new Philips Hue lighting products to its ever-growing range, as well as a new switch designed to make it easy to dim lights and select scenes. Additionally, the Hue app has been updated to offer a new Sunrise option to smart home owners, allowing existing color lights to mimick the colors of a sunrise to gently wake you in the morning … New Philips Hue track lighting systemPerhaps the most interesting option is a flexible track lighting system. In a way, this is mood lighting come full circle! Way before smart lighting, you could buy colored spotlights to fit to a ceiling track, to create color casts on walls. Now Hue owner Signify has brought track lighting up to date. Key to the new product is its flexibility, letting you mix-and-match different types of lights.
Battery-powered table lampThe first Hue Go battery-powered lamp was launched back in 2017, and remains popular today for subtle mood lighting. But the latest addition to the portable Go range is a more practical table lamp.
Other new Philips Hue lightsThere are a couple of new gradient lamps, which allow a mix of colors to be displayed at the same time.
There are also a couple of bathroom ceiling lights designed to cope with a high humidity environment.
Philips Hue switch for easy dimming and scene selectionA new Tap dial switch offers four programmable buttons intended for scene selection, while the rotary dial around the outside allows easy dimming.
Sunrise wake-up sceneThe Hue app already offers a gentle wake-up scene, designed to gradually fade in light, and this has now been supplemented by a new Sunrise option.
Pricing and availability of the new Philips Hue productsSome are available from today in Europe, while the US will need to wait until later in the summer.

| Microsoft Plans to Eliminate Face Analysis Tools in Push for ‘Responsible A.I.’ - The New York Times Posted: 21 Jun 2022 09:02 AM PDT  The technology giant will stop offering automated tools that predict a person's gender, age and emotional state and will restrict the use of its facial recognition tool. For years, activists and academics have been raising concerns that facial analysis software that claims to be able to identify a person's age, gender and emotional state can be biased, unreliable or invasive — and shouldn't be sold. Acknowledging some of those criticisms, Microsoft said on Tuesday that it planned to remove those features from its artificial intelligence service for detecting, analyzing and recognizing faces. They will stop being available to new users this week, and will be phased out for existing users within the year. The changes are part of a push by Microsoft for tighter controls of its artificial intelligence products. After a two-year review, a team at Microsoft has developed a "Responsible AI Standard," a 27-page document that sets out requirements for A.I. systems to ensure they are not going to have a harmful impact on society. The requirements include ensuring that systems provide "valid solutions for the problems they are designed to solve" and "a similar quality of service for identified demographic groups, including marginalized groups." Before they are released, technologies that would be used to make important decisions about a person's access to employment, education, health care, financial services or a life opportunity are subject to a review by a team led by Natasha Crampton, Microsoft's chief responsible A.I. officer. There were heightened concerns at Microsoft around the emotion recognition tool, which labeled someone's expression as anger, contempt, disgust, fear, happiness, neutral, sadness or surprise. "There's a huge amount of cultural and geographic and individual variation in the way in which we express ourselves," Ms. Crampton said. That led to reliability concerns, along with the bigger questions of whether "facial expression is a reliable indicator of your internal emotional state," she said. The age and gender analysis tools being eliminated — along with other tools to detect facial attributes such as hair and smile — could be useful to interpret visual images for blind or low-vision people, for example, but the company decided it was problematic to make the profiling tools generally available to the public, Ms. Crampton said. In particular, she added, the system's so-called gender classifier was binary, "and that's not consistent with our values." Microsoft will also put new controls on its face recognition feature, which can be used to perform identity checks or search for a particular person. Uber, for example, uses the software in its app to verify that a driver's face matches the ID on file for that driver's account. Software developers who want to use Microsoft's facial recognition tool will need to apply for access and explain how they plan to deploy it. Users will also be required to apply and explain how they will use other potentially abusive A.I. systems, such as Custom Neural Voice. The service can generate a human voice print, based on a sample of someone's speech, so that authors, for example, can create synthetic versions of their voice to read their audiobooks in languages they don't speak. Because of the possible misuse of the tool — to create the impression that people have said things they haven't — speakers must go through a series of steps to confirm that the use of their voice is authorized, and the recordings include watermarks detectable by Microsoft. "We're taking concrete steps to live up to our A.I. principles," said Ms. Crampton, who has worked as a lawyer at Microsoft for 11 years and joined the ethical A.I. group in 2018. "It's going to be a huge journey." Microsoft, like other technology companies, has had stumbles with its artificially intelligent products. In 2016, it released a chatbot on Twitter, called Tay, that was designed to learn "conversational understanding" from the users it interacted with. The bot quickly began spouting racist and offensive tweets, and Microsoft had to take it down. In 2020, researchers discovered that speech-to-text tools developed by Microsoft, Apple, Google, IBM and Amazon worked less well for Black people. Microsoft's system was the best of the bunch but misidentified 15 percent of words for white people, compared with 27 percent for Black people. The company had collected diverse speech data to train its A.I. system but hadn't understood just how diverse language could be. So it hired a sociolinguistics expert from the University of Washington to explain the language varieties that Microsoft needed to know about. It went beyond demographics and regional variety into how people speak in formal and informal settings. "Thinking about race as a determining factor of how someone speaks is actually a bit misleading," Ms. Crampton said. "What we've learned in consultation with the expert is that actually a huge range of factors affect linguistic variety." Ms. Crampton said the journey to fix that speech-to-text disparity had helped inform the guidance set out in the company's new standards. "This is a critical norm-setting period for A.I.," she said, pointing to Europe's proposed regulations setting rules and limits on the use of artificial intelligence. "We hope to be able to use our standard to try and contribute to the bright, necessary discussion that needs to be had about the standards that technology companies should be held to." A vibrant debate about the potential harms of A.I. has been underway for years in the technology community, fueled by mistakes and errors that have real consequences on people's lives, such as algorithms that determine whether or not people get welfare benefits. Dutch tax authorities mistakenly took child care benefits away from needy families when a flawed algorithm penalized people with dual nationality. Automated software for recognizing and analyzing faces has been particularly controversial. Last year, Facebook shut down its decade-old system for identifying people in photos. The company's vice president of artificial intelligence cited the "many concerns about the place of facial recognition technology in society." Several Black men have been wrongfully arrested after flawed facial recognition matches. And in 2020, at the same time as the Black Lives Matter protests after the police killing of George Floyd in Minneapolis, Amazon and Microsoft issued moratoriums on the use of their facial recognition products by the police in the United States, saying clearer laws on its use were needed. Since then, Washington and Massachusetts have passed regulation requiring, among other things, judicial oversight over police use of facial recognition tools. Ms. Crampton said Microsoft had considered whether to start making its software available to the police in states with laws on the books but had decided, for now, not to do so. She said that could change as the legal landscape changed. Arvind Narayanan, a Princeton computer science professor and prominent A.I. expert, said companies might be stepping back from technologies that analyze the face because they were "more visceral, as opposed to various other kinds of A.I. that might be dubious but that we don't necessarily feel in our bones." Companies also may realize that, at least for the moment, some of these systems are not that commercially valuable, he said. Microsoft could not say how many users it had for the facial analysis features it is getting rid of. Mr. Narayanan predicted that companies would be less likely to abandon other invasive technologies, such as targeted advertising, which profiles people to choose the best ads to show them, because they were a "cash cow."
