Can we communicate directly with the brain through the sense of touch?
Yes, we can!
There are devices by which you can see through electrotactile signals to your tongue (BrainPort) and hear through vibrotactile signals to your torso (Vest). Amazingly, the brain is still able to interpret the information as sound and vision, making you see and hear!
With Xtactor Smart Wristband (the screenless smartwatch) you get information from your smartphone through vibrotactile signals on your wrist!
After some training, you will be able to interpret the signals almost instinctively!
