The Cambridge lab where they test how elderly people use technology
Must-have modern gadgets are designed by young people with young people in mind - that is the view of Ian Hosking, who works at Cambridge University's Design Centre.
This can mean that elderly people, who have much to gain from modern technology, feel excluded.
Mr Hosking's mission is to improve the accessibility of modern, mass-produced devices like smartphones and tablets. To this end, he conducts experiments with volunteers.
BBC News caught up with him and his team at his lab, while they were working with his latest recruit, 75-year-old Archie Ferguson.
He'd just finished a round of golf, but admitted to feeling 'frustrated, angry and a bit of a wally' when he tried to use a modern smartphone.
The Design Lab conducts tests on individual products, but the general findings that Mr Hosking discusses here apply to digital communication devices across the market.
