In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

Producing mobile phones for older customers requires much more than big buttons and a simple interface. At Mobile World Congress last month we spoke to two major players in this growing sector: Swedish company Doro and Austria's Emporia Telecom.

Our first conversation was with Harald Obereder, Chief Technology Officer at Emporia, who spoke to Mark Bridge about handset design and user interface design. This was followed by an interview with Chris Millington, Managing Director for Doro UK and Ireland, about research and development in the 'senior tech' market.

In this special feature we're talking to Chris Millington, Doro's MD for UK and Ireland. Doro, which produces easy-to-use mobile phones for older people, is releasing its first touch-screen smartphone this month.

As well as explaining the phone's benefits, Chris also describes the advantages of Doro's tablet and PC software. In addition, we take a few minutes to look at Doro's plans for the future.

Colin Aitken from Burnside Telecom talks about the company's new mobile telecare products: the MoniCare GSM remote monitoring solution and a 'fixed cellular phone' designed as a landline alternative for elderly users.

Mobile usability is the main topic of this special podcast, which includes Chris Millington from Doro UK and Jérôme Nadel of MobiWire (recorded at Mobile World Congress). Conversation topics include the user interface, encouraging usage and designing mobile phones to suit a specific customer group.
