Abstract
A second touch area provided on the back side of the mobile phone in a location such that an index finger can be used to provide input when while the mobile phone is being held in that one hand. A second hand is not required for the various types of input that are provided using this second touch area. This allows the mobile phone to be used in single-handed operation in many circumstances.
