Those things already exist. You can get g-force monitors to see if people have fallen and ...
Yes, I know, however, we were asked to cover the "20" bit of the 80/20 rule and (crucially) not to depend on instrumenting the individual directly. That means accelerometers and magnetometers (for example) are out for posture detection and in with OpenCV. Same for temperature (microbolometers, not thermocouples). Way too many corner cases for my liking with either approach.
