On such an opportunity is perfectly exemplified in CAALYX.
In fact, mobile phones lend themselves very well to location-based technologies, as David Sym-Smith cleverly notes: " Prior to mobile phones, the most common opener to a telephone conversation was 'How are you?' Today, on a wireless phone, more conversations open with 'Where are you?'" Such GPS-enabled mobile phones (GPS-enabled cameras and other gadgets also exist) will not just enable millions of people to collectively annotate the Earth in ways never done before, but will also open many other exciting and much needed location-based service possibilities and opportunities. The year 2007 has been described as 'the year of Global Positioning System (GPS)-enabled mobile phones' par excellence. A recent conference workshop, Locare '06, was fully dedicated to the subject of 'location-based services for healthcare'. These rapid developments have made their use in mission-critical tele-care and healthcare delivery significantly more prevalent today than it was in the near past. Since then, location-aware applications and services, and location-sensitive mobile devices have undergone major improvements, and have become more widely available and less expensive. Back in January 2003, we explored the concept of 'location-based health information services', and presented it as a new paradigm in personalised health information delivery.
