Joe Killen of Tunstall Group talks about the technology and services his 60-year-old company is offering to elders or people with chronic diseases, still living in their homes. He tells us a lot about the quite new (about 5-years-old) and innovative tele-health monitoring schemes, which are gaining ground, all over the world. Joe points out the need for standards, now that we have an abundance of biometric data concerning millions of people, as European population is getting older, and proposes the creation of a common international framework for that purpose.
