Florence Chan's award-winning AI vision tool helps the blind navigate their world
Great minds blazing a trail: meet the women who are leading the way in the realm of science and invention.

In 2019, Florence Chan was in the third year of her PhD in biomedical engineering. Her research focused on using
artificial-intelligence vision to recognise the status of cells , differentiating between stem cells, cancerous and healthy ones. She was impressed with how efficient AI was in recognising their subtle differences. One day, while taking a break from the lab, she was strolling through a shopping centre when she spotted a group of visually impaired people navigating the mall with the traditional tools of the blind: canes and guide dogs. She wondered, 'Could AI vision support them?'
That penny-drop moment catapulted her into action and soon she was in touch with the
Hong Kong Society for the Blind and speaking to the visually impaired about what could best help them. Tools available in Europe and the United States that rely on GPS don't work well in densely populated cities such as Hong Kong, because of interference from multiple devices.
Chan was already having a busy year. Pregnant with her first child, she spent her maternity leave preparing a business proposal for an incubation programme, pitching it to the Hong Kong Science and Technology Park. It worked, and in 2020, she co-founded AI Guided, aiming to create a device that allowed AI to be eyes for the visually impaired.
Beginning with a rough idea on paper, she and her team worked through 20 prototypes over five years. They experimented with devices that could be worn on the chest and head, or as glasses, and eventually settled on a belt.

The
GUIDi Smart Belt is worn around the waist and scans the surrounding area with advanced AI vision technology. It emits gentle vibrations from various points on the belt, warning the user of obstacles ahead, allowing them to walk with confidence.

Meta in talks for Scale AI investment that could top US$10 billion
Meta Platforms is in talks to make a multibillion-dollar investment into artificial intelligence start-up Scale AI, according to people familiar with the matter. The financing could exceed US$10 billion in value, some of the people said, making it one of the largest private company funding events of all time. The terms of the deal are not finalised and could still change, according to the people, who asked not to be identified discussing private information. Representatives for Scale and Meta declined to comment. Meta Founder and CEO Mark Zuckerberg waves before speaking at LlamaCon 2025, an AI developer conference, in Menlo Park, California, April 29, 2025. Photo: AP Scale AI, whose customers include Microsoft and OpenAI, provides data labelling services to help companies train machine-learning models and has become a key beneficiary of the generative AI boom. The start-up was last valued at about US$14 billion in 2024, in a funding round that included backing from Meta and Microsoft. Earlier this year, Bloomberg reported that Scale was in talks for a tender offer that would value it at US$25 billion. This would be Meta's biggest ever external AI investment, and a rare move for the company. The social media giant has before now mostly depended on its in-house research, plus a more open development strategy, to make improvements in its AI technology. Meanwhile, Big Tech peers have invested heavily: Microsoft has put more than US$13 billion into OpenAI while both and Alphabet have put billions into rival Anthropic.

AI scientist De Kai offers a new vision for ‘parenting' AI to avoid our own demise
For years, the story of artificial intelligence (AI) has been cast as a high-stakes contest between the US and China – a technological arms race with global consequences. But to De Kai, a pioneering machine learning scientist and advocate for AI ethics, this framing fundamentally misunderstands the technology. 'I would prefer to think about it as the AI climate change challenge,' De Kai said in an interview with the Post at the Hong Kong University of Science and Technology, where he is a professor of computer science and engineering. 'Literally, AI is a change to the [social] climate that humanity is competing in.' De Kai, whose surname is Wu but who professionally goes by only his given name, has spent four decades at the forefront of AI research, going back to his work in natural language processing during his PhD at the University of California, Berkeley, in the early 1980s. His new book, Raising AI: An Essential Guide to Parenting Our Future, released on June 3, argues that living with AI requires a paradigm shift – one in which people 'parent' these systems as if they were their children. 'What's the single thing in folks' lives that makes them most want to become better versions of themselves?' De Kai writes. 'Having kids, most grown folks say.' Since AI is learning by absorbing everything we do and say online, we need to be conscientious about who we are around our AI 'children', the argument goes. De Kai's book Raising AI makes an argument for treating AI as children that must be parented by good role models.

AI content detector: why does China dismiss it as ‘superstition tech'?
With the graduation season approaching, many Chinese universities have introduced regulations setting clear requirements for the proportion of artificial intelligence -generated content – or the 'AI rate', as it is called – in theses. Advertisement Some universities have used the AI rate as a deciding factor in whether a thesis is approved. The rule is intended to prevent academic misconduct, as educators have become increasingly concerned about the unregulated use of AI in producing scholarly literature, including data falsification and content fabrication, since the public debut of generative AI models such as ChatGPT However, an official publication of the Ministry of Science and Technology has warned that using AI content detectors to identify AI writing is essentially a form of 'technological superstition' that could cause many unintended side effects. AI detection tools could produce false results, the Science and Technology Daily said in an editorial last Tuesday, adding that some graduates had complained that content clearly written by them was labelled as AI-generated. Advertisement Even a very famous Chinese essay written 100 years ago was evaluated as more than 60 per cent AI-generated, when analysed by these tools, the article said.
