Abstract

A mobile phone including a housing, a display encased in the housing, viewable outside the housing through the upper surface of the housing, wherein the upper surface has no movable buttons and no movable switches, a touch sensor detecting touch inputs performed on the upper surface, and a processor mounted in the housing receiving output from the touch sensor and rendering output on the display in response to the received touch sensor outputs.

         19 . A mobile phone comprising:
 a housing;   a display encased in said housing, viewable outside said housing through the upper surface of said housing, wherein the upper surface has no movable buttons and no movable switches;   a touch sensor detecting touch inputs performed on said upper surface; and   a processor mounted in said housing receiving output from said touch sensor and rendering output on said display in response to the received touch sensor outputs.   
     
     
         20 . The mobile phone of  claim 19 , wherein the upper surface comprises at least one representation of a function beyond an edge of said display, wherein said touch sensor detects touch input on the at least one representation. 
     
     
         21 . The computer readable medium of  claim 20 , wherein the at least one representation represents a keyboard function, and wherein in response to touch sensor outputs related to the representation, said processor renders a keyboard on said display. 
     
     
         22 . The computer readable medium of  claim 20 , wherein the at least one representation represents a general application dependent function, and wherein in response to touch sensor outputs related to the representation, said processor renders icons representing additional functions on said display. 
     
     
         23 . The computer readable medium of  claim 20 , wherein the at least one representation represents a task manager function, and wherein in response to touch sensor outputs related to the representation, said processor renders representations of available applications on said display.
