tube / Cell phone

I think that cell phone of future must have very simple shape but in the same time contain large quantity of additional functions. Present conceptual cell phone in the form of the tube haven’t habitual constant screen. This cell phone have translucent air screen which appears only at necessity. This conceptual cell phone made from cilynder metal tube and have three control buttons and scrolling ring also able to move slightly in left or right side. This scrolling ring play a role of the navigation joystick. Rough textured surfaces of metal buttons and a scroll ring harmony accented its tactile functions.
