AI software for smart glasses wins £1m prize for technology to help people with dementia
AI software that can be embedded into smart glasses has won a £1m prize for technology to help people with dementia.Built into chunky, black-rimmed frames that have a camera, microphone and speakers, the tech – known as CrossSense – guides wearers through everyday life by means of a chatty assistant called Wispy.Not only can Wispy offer prompts and feedback during tasks – through verbal cues and text that floats in front of the wearer’s eyes – but it can also ask questions, engage in light conversation and aid reminiscences.The software has won the Longitude prize on dementia, one of a number of awards designed and delivered by Challenge Works and supported by Nesta.Funded by Alzheimer’s Society and Innovate UK, the prize aimed to encourage the development of technology to help people with dementia stay independent for longer.
About 150 million people globally are expected to be living with dementia by 2050.Szczepan Orlins, the chief executive of CrossSense Ltd, said the prize money would help to bring the company’s product to market.He said a smartphone version would be available at the end of this year and the CrossSense-enabled smart glasses were expected to be available in early 2027.Orlins added that while CrossSense Ltd provided the AI software, the team had been working with frames produced by various hardware companies.These can be fitted with prescription lenses and are compatible with hearing aids.
“With the prize, we will be running a pilot with smart glasses in the last quarter [of 2026] for four weeks in people’s homes, which would give us enough data to know that this is ready,” Orlins said.Orlins said information such as the level of care the wearer needs could be entered in an accompanying app, and Wispy used machine learning to adapt to users’ needs – including changes in their condition.The CrossSense technology is expected to cost about £50 a month per subscription, while the smart glasses cost up to £1,000 – although they may become cheaper.The CrossSense-enabled smart glasses will initially be marketed directly at consumers and the aim is that they will eventually be available through the NHS.Prof Julia Simner, of the University of Sussex, who was the science lead for the team, tested CrossSense with 23 pairs of people living with dementia and their carers.
The study, which has not yet been peer-reviewed, revealed that without the smart glasses, participants with dementia could name only 46% of household items correctly.With the glasses, the figure was 82%.“Crucially, the benefit lasted even after the glasses were removed,” Simner said, adding that an hour after taking the glasses off the figure was 78%.Dr Foyzul Rahman, an expert in cognitive decline at Loughborough University who was not involved with the project, said the breakthrough made by CrossSense was offering real-time prompts and feedback during tasks rather than providing simple one-off reminders.Rahman said larger, more carefully controlled studies or randomised trials were needed to test whether such devices delivered meaningful benefits in everyday life, while there were also ethical considerations over consent, given the technology will collect data from the wearer.
He also said a challenge for assistive technologies was whether people would really use them.In particular, he noted the battery life for the smart glasses was only one hour, meaning a portable power bank was required.But for Carole Greig, 70, who was diagnosed with Alzheimer’s almost three years ago and has tested the CrossSense-empowered glasses, the technology is exciting.“For people with the condition like mine who’ve got cognitive impairment, it’s just an amazing thing,” she said.“How fantastic that we can be given some more independence, that we’re going to be able to cope on our own and not be a burden.
And not only that, it’s not just [not] being a burden, it’s enjoying your life.”
Jack Draper adds new string to his bow as he rebuilds his game
Two and a half hours into one of the most unforgettable battles of his career, Jack Draper resolved to attack without hesitation, regardless of the outcome. On two pivotal points in his Indian Wells fourth-round match against Novak Djokovic, at 4-4 in the tie-break and then on match point at 6-5, Draper forced himself inside the baseline and unleashed two backhands, those shots driving him to victory.It would have been understandable for Draper to have played passive tennis in those decisive moments. Not only did Indian Wells mark his second ATP tournament back after sustaining a bone bruise to his left arm that forced him off the tour for seven months, the injury has forced him to make dramatic changes to his game.Draper returns to the circuit using natural gut strings in a hybrid string setup
Judge in rugby brain injury lawsuit tells legal teams to hurry up as cases drag on
The judge overseeing the pretrial phase of the two landmark litigation cases about brain injuries in rugby has issued another rebuke to the legal teams on both sides over their lack of progress.Senior Master Jeremy Cook started the latest round of case management hearings by reminding both the defendants and the claimants that “it won’t have escaped anybody’s notice that some of these claims are now over five years old, and we haven’t made much progress”.Since the cases involve claims of degenerative brain diseases, Cook said, time is at a premium. He has told both sides to provide him with written updates between now and a scheduled case management hearing in October, when both sides will be required to have identified their lists of 28 lead claimants from among the hundreds involved.The idea is these 28 will then be whittled down into a smaller group, who will represent the entire cohort
The WNBA’s new labor deal explained: what it means for pay, power and the league’s future
The WNBA and its players’ union (WNBPA) have reached a verbal agreement on a new collective bargaining agreement, ending 17 months of negotiations after players opted out of the previous deal and averting mounting fears of a strike.The agreement would be the sixth in league history and is being framed by both sides as a major step forward for player empowerment and the league’s growth.Commissioner Cathy Engelbert said Wednesday the two sides have “aligned on key elements”, though a formal term sheet still needs to be finalized. Union leaders echoed that sentiment, calling the deal a reflection of players using their collective voice.Full details have not yet been released, and the agreement must still be ratified
Oh deer! Rory McIlroy puts elk on the Masters champions dinner menu
Elk as the key to Masters success: who had any i-deer? Rory McIlroy will serve starters made from the meat of the North American animal at Augusta National next month in tribute to his food of choice before winning the Masters last year.The wine McIlroy drank to toast victory, food that conjures memories of his childhood in Belfast and a dish made by his mother, Rosie, also feature in the Masters champion’s dinner for 2026. In a nod to the venue’s attention to detail, McIlroy revealed that chefs from Augusta made a special visit to a New York restaurant to replicate his favourite tuna recipe.McIlroy will begin his Masters defence from 9 April. Two days earlier, he hosts fellow past winners in the annual gathering in the Augusta clubhouse
‘People will always hate but my opinion is all that matters’: GB sprinter Amy Hunt on fame, abuse and becoming ‘an icon’
The 23-year-old who went viral last year has plenty of targets for 2026, starting with the World Indoor Championships in PolandAmy Hunt’s mind is flashing back to the moment she unwittingly went viral last September. As untrammelled joy charged through her body, the BBC asked about her unusual journey from an English degree at Cambridge to a shock 200m world championship silver medal. Hunt’s response quickly became a cri du coeur to young girls everywhere: “You can be an academic badass and a track goddess.”As the 23-year-old prepares for the World Indoor Championships in Poland that start on Friday, she reveals her remark was entirely spontaneous. “As soon as I said it, I was like: ‘Oh my gosh, I’m on the BBC, can I even say that? Are they going to bleep that out?’” she says, smiling
Other nations danced for joy at the World Baseball Classic. Team USA played toy soldiers
On the morning of the World Baseball Classic final between the United States and Venezuela, the headline of the New York Times daily briefing read, “America, alone,” in reference to the unwillingness of the country’s traditional allies to join the war with Iran. The revived rhetoric of America First, once a restoration of the isolationist, often Nazi-sympathetic sentiments of the 1930s, has coalesced into current policy, status, attitude: America by itself, making its own rules, intent on largely playing alone by them.Venezuela won the final, thrillingly, 3-2 over Team USA, but not before the hosts extended that isolationism with a sourness that produced a comically vapid extension of American bravado, and nearly undermined a tournament that in its 20th year is at last becoming one of baseball’s great successes.The WBC was a two-week block party. Canada, fresh off the Toronto Blue Jays’ American League pennant, reached the quarter-finals for the first time
