Falls prediction

You are right to point out that the technology to do this is already ubiquitous. However, I'm of the opinion that the people who we need to identify are those who do not want to be monitored and who don't want to be told of their vulnerability. They would hate to be called patients!

I guess that every big telecoms company wants a slice of the social and medical care market. They don't want to be only the bit carriers. I'm afraid that BT failed 4 times to enter the social alarm (i.e. PERS) market - so AT&T could face an uphill battle to take on the likes of GE, Philips, Siemens and Intel.

I believe that mobile phone technology will play a big part in telecare services in about 10 to 15 years, when older people are used to the devices. Meanwhile, I see a line drawn between devices for mobile care (for everyone) and those based in the home (for house-bound older people).
