While we're on tech I would love to be able to monitor my relatives fluid intake (and urine output) - fairly convinced that they never drink water and so are often mildly dehydrated thus risking kidney and bladder problems.
I think monitoring should stop where we would all stop if actually present - this could be different places for different people but for most would be OK to know someone had got into bed or out of bed, or gone into bathroom, but not to go any further than that.
That would be very interesting, Houdini, we haven't thought of dehydration. It's relatively easy to track using video monitoring, as well as being an important metric and a starting point for different affections.
I agree that people should be able to stop the cameras whenever they want and also be free to configure the system according to their needs.
To move our project forward and further investigate what people think about video monitoring for preventive medicine we created a website. Please have a look if you have 1 minute and it would be very useful to get your feedback: http://machinemedicine.com/
Thanks again!
