"The team also tested the device out on non-amputees for correlation. Surprisingly, the intact testers had a lower success rate in detecting texture, reporting a 77 per cent success rate."
Not really surprising, IMO. In the non-amputees the data from the sensor is additional data as the native sensors are still active. They are active and transmitting all the time, you're just usually not aware of it because your brain/mind filters the data.
The scientists saw brain activity in exactly the spot where you'd expect for handling touch sensations.
Brains are amazing, aren't they? AI has a long way to go yet.
A very good description about what goes on in your mind when you touch and feel things can be found in a book about motorcycling by Dr. Berndt Spiegel, "The Upper Half of the Mororbike".
