In communication units the input and/or output of data is normally performed using keypad input, voice input/output or display output. This limits the input/output of the communication unit. The claimed invention proposes a new way of inputting/outputting of data by providing a communication unit with intra-changeable elements, where the physical properties of the elements are changed by an electrical or a mechanical signal/input and that the elements are used in the user interface of the communication unit to enable flexible input and output of data from the communication unit. The user input and output is thereby including a sensory indication, including a physical and/or visual dimension.
