Claim:
A finger gesture user interface for an electronic device comprising: a housing for an electronic device comprising: a front opening in a front outer surface of the housing; a rear opening in a rear outer surface of the housing; and inner sidewalls extending from said front opening to said rear opening to form a cavity for inserting a finger therein in a direction from front-to-rear to perform a translation gesture, and for inserting a finger therein in a direction from rear-to-front to perform a translation gesture; a display mounted in said housing, wherein the whole cavity is disposed along a side of the display, separate from the display; a detector mounted in said inner sidewalls, operable to detect the front-to-rear translation gesture and to detect the rear-to-front translation gesture; and a processor connected to said detector and to said display for interpreting a detected translation gesture as a user interface input command to modify a graphic rendered on said display.
