Is it possible to calculate the weight of a person by only using his smartphone, some action he must perform (jump, rotate etc.) and some data like his height or age.
Current smartphones have the following sensors/instruments: G-Sensor Digital compass Proximity sensor Ambient light sensor GPS
In conjunction with the data those devices would provide could we somehow get the approx. weight of a person?
I was thinking of like asking the person to jump and then calculate the downward velocity but that is more indicative of the persons physical strength then weight...
