AI Smart Glasses Win £1M Longitude Prize for Dementia Care

CrossSense, a technology startup focused on assistive devices, has won the prestigious Longitude Prize on Dementia with its innovative AI-powered smart glasses designed to help people living with dementia navigate their daily lives. The prize, worth £1 million, recognizes the most transformative technology for improving the quality of life of people with dementia.

The smart glasses use artificial intelligence to identify everyday objects in the wearer's environment and provide real-time audio guidance to help them complete daily tasks. For someone with dementia who may struggle to recognize a toothbrush or remember the steps involved in making a cup of tea, the glasses act as a patient, ever-present companion that gently guides them through each activity.

“The prize, worth £1 million, recognizes the most transformative technology for improving the quality of life of people with dementia.”

In testing, the results were striking. Participants using the CrossSense glasses improved their ability to identify everyday items from just 46% to 82% — a dramatic improvement that translates directly into greater independence and confidence in daily life. The glasses essentially bridge the gap created by cognitive decline, allowing wearers to maintain their autonomy for longer.

The technology works by combining a lightweight camera embedded in the glasses' frame with advanced computer vision algorithms running on a connected device. When the wearer looks at an object, the AI identifies it and provides contextual information through a discreet speaker. The system learns the user's home environment over time, becoming more accurate and personalized with continued use.

The Longitude Prize on Dementia was established to catalyze innovation in dementia care, an area that has historically received less technological attention than other major health conditions. With an estimated 55 million people worldwide living with dementia and numbers expected to rise sharply as populations age, tools that can extend independence and quality of life are urgently needed.

CrossSense's victory highlights the potential for AI-assisted technology to make a genuine difference in the lives of vulnerable people. The company plans to use the prize funding to refine the product and begin wider deployment, with the goal of making the glasses available through healthcare systems and directly to families caring for loved ones with dementia.
