Emergency button — A Telco 2.0 application in the e-health environment

The paper presents the idea of Telco 2.0 with an e-health usage scenario. Since numerous elderly people are going missing every year, proposed emergency location service depicts a way in which mobile operators' networks, the Internet and possibilities given by rapid improvement of smart-phones' functionalities can converge in order to relieve the problem. The descriptions are supplemented with sets of accuracy measurements and usability tests, conducted during test deployment in Polish Orange Labs R&D Centre. The results confirm usability potential of the service, giving green light for further research and development. Still, in order to make the service reliable, the algorithms used to determine location and detect falls need to be improved.
