AI-Powered Smart Glasses Win £1 Million Prize for Dementia Support
A groundbreaking AI-powered assistant, designed for smart glasses, has been awarded the £1 million Longitude Prize on Dementia. Developed by London-based CrossSense Ltd., the technology, called CrossSense, aims to help individuals with early-stage dementia maintain independence and live safely in their own homes for longer. Alzheimer’s Society announced the award on Wednesday, March 18, 2026.
How CrossSense Works
CrossSense utilizes a personalized AI companion, named Wispy, to identify everyday objects and guide users through daily activities. Wispy learns a person’s unique routines and adapts to their changing needs as dementia progresses. The smart glasses capture the user’s environment, and the AI interprets this information to provide assistance with tasks like making a cup of tea, getting dressed, managing household chores, and interacting with loved ones. CrossSense focuses on empowering users to make their own choices, offering helpful prompts and suggestions rather than dictating actions.
Promising Results from Initial Trials
Early testing of CrossSense has shown significant positive impacts. A study involving 23 pairs of individuals with dementia and their caregivers revealed that participants could correctly name 46% of household items without the glasses. With CrossSense, that number jumped to 82%. Importantly, the benefits persisted even after the glasses were removed, with participants correctly identifying 78% of items an hour later. The Guardian reported on these findings.
Availability and Future Plans
CrossSense plans to release a smartphone version of the AI assistant later in 2026. The CrossSense-enabled smart glasses are expected to be available for purchase in early 2027. The company is currently seeking participants for a four-week pilot program in the UK later in 2026 to gather further data and refine the technology. The subscription cost is anticipated to be around £50 per month, with the smart glasses themselves costing up to £1,000, though prices may decrease. CrossSense aims to eventually make the technology available through the National Health Service (NHS).
Expert Perspectives
Dr. Foyzul Rahman, a cognitive decline expert at Loughborough University, highlighted the significance of CrossSense’s real-time prompts and feedback, differentiating it from simple reminder systems. However, he emphasized the need for larger, more controlled studies to confirm the technology’s benefits and address ethical considerations related to data collection and user consent. The Guardian reported on Dr. Rahman’s comments.
A User’s Perspective
Carole Greig, a 70-year-old woman diagnosed with Alzheimer’s disease, who participated in testing, expressed her enthusiasm for the technology. She stated that CrossSense offers the potential for increased independence and a better quality of life for individuals living with dementia. The Guardian quoted Ms. Greig’s positive experience.
