Smartag technology for demented people watches

[Yanky-G]

Need to discuss the characteristics and the way to apply 

[IndiW]

Absolutely wonderful thinking

I think general technology is almost ready and available

For example, leaving the house without closing the door, then phone can alert or the watch can alert, turning off gass if not being used, etc

Medication reminders and reorder etc

It's a matter of different services working together

Almost certainly the data is already available, just needs connecting up. Look towards Building Management Systems and Security Systems

Absolutely, even the location, for example some patients with poor memory go missing and having a GPS wrist band will be very useful
