Abstract
An interface apparatus includes a main unit, an array of interface modules, driver circuitry, and a remote unit. The main unit outputs files to an output unit, is detachably couplable to interface modules and assigns content identifiers to interface modules. The array presents an image to the user and each interface module can be engaged by a user. The driver circuitry is adapted to drive the array to present an image to the user based upon the user's engagement with an interface module. The remote unit is coupled to the output unit and can be detachably coupled to the interface module. When coupled to the interface module, the remote unit can access the assigned identifier and transmit a request signal to the main unit based on the identifier. The request signal is adapted to cause the main unit to output a file identified by the identifier to the output unit.
