A User Interface

A user interface for an interactive device, the user interface comprising:

• an interactive surface formed by an array of displaceable surface members;
• an oscillatory signal generator configured to generate an oscillatory signal;
• and
• characterized by:
• a cable array coupled to the oscillatory signal generator, wherein the surface members are connected to the cable array such that the oscillatory signal is carried from the oscillatory signal generator to the surface members, and
• wherein the surface members have a resting position with respect to the cable array and movement of the surface members from the resting position causes the cable array to move thereby adjusting the oscillatory signal to produce a modified oscillatory signal and/or a modified oscillatory signal causes the cable array to move thereby forcing the surface members to move from the resting position;
• the user interface further comprising a signal converter which converts the modified oscillatory signal to and/or from an electrical signal of the interactive device.
