Then why do you keep asking to have "groups of people," and "control groups"? That doesn't make any sense when testing a device. With a device, you just test it to see if it works or not. I don't see how groups would fit into a test like that.
Because all the definitions of double blind testing have similar wording
Then it is not a double blind test..ArtI don't see how groups would fit into a test like that.
