Abstract

A dynamic user interface (1000) is configured to present one of a plurality of keypad configurations to a user. Each keypad configuration includes a plurality of user actuation targets that may be selectively presented to, or hidden from, a user. A segmented optical shutter (204) having segments (801,802,803,804) configured for selective transition from opaque to translucent states is disposed above an segmented optical shutter (204) having a plurality of transparent electrodes (901), each operating as an electroluminescent element. When each segment (801) is active and in a transparent state, a corresponding electroluminescent element is actuated so as to project light (1001,1002) both through the corresponding segment (801) at a first luminosity and about the corresponding segment (801) at a second luminosity, so as to circumscribe the segment (801). The illuminated segment (801) and the circumscription (1004) together form a user actuation target.
