BenQ's black box

Let you guess 10 times what the black box on the right is? If your first answer is a mobile phone, then you must be its designer. Indeed, this is the BenQ-Siemens concept phone - black box. This phone has no keyboard, not even any buttons; instead it uses a full touch screen as its panel. When you select different functions, it automatically switches between different interfaces (as shown in the figure). Although such a phone may not necessarily go into production and reach the market, it already feels pretty cool to share such a concept with its designer.
