Abstract (en)
A keypad for a mobile device having a housing comprises a plurality of keys coupled to the housing. Each of the keys has means for making the selection of smaller key sizes easier for a user. The keys may incorporate a flexible or resilient upper part, or be configured to transform to a larger surface area upon the application of pressure. The keys may be configured to rotate away from a selected key. The keys adjacent a selected key may be configured to lock mechanically or electrically. The keys may have multiple parts that are movable relative to one another. The upper part of the key may include a fluid, with a selection rod positioned inside the upper part to enter the fluid.
