Such convexity will be imposed only on the virtual keyboard. When the keypad is not needed, the liquid is moved back into the reservoir. It is also possible to individually adjust the size of the keys, a change in pressure. To operate a keyboard requires very little power. It is expected that this technology will soon be used in different applications and games.
