New mobile phone with the easier and lighter concept by turning your hand into a mobile phone. 'Finger Touching', designed by Sunman Kwon at Hong-ik University in South Korea, it slips onto your hand, and then projects a 3x4 mobile-style keypad onto your fingers, with each joint making up a button.
"Human hand is the most basic communication method. For easier and simpler controls, it uses the instinctive input method â€œfinger jointâ€. Excluding the thumb, each finger joint makes up twelve buttons. These â€œknuckle buttonsâ€, based on the cell phone's 3x4 keypad, are likely to become the most popular input method."
