Abstract
Abstract An improved user interface for a cellular telephone system subscriber unit, including the following functions: (1) a predictive keyboard input method for speeding up input on a telephone with a space limited keyboard; (2) a word completion method for speeding up input; (3) a distinctive signaling method useful in a dual-mode or tri-mode cellular phone system that incorporates both voice call functionality and data messaging functionality; (4) a secret message method that permits secret messages to be received by an authorized user of a cellular telephone that includes a data messaging capability; (5) a message screening method that permits a user to set a message screening mode in a cellular telephone; (6) an improved “scratchpad” method which permits a user to enter a telephone number into a storage register of a cellular telephone while in the middle of a voice call, visually verify the entry, and then save the number to a rapid redial location for later use; (7) a global search method for searching text strings in all of the different memory sections of a cellular telephone having an address book, a hierarchical menu structure, and stored data messages.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
In a cellular telephone having an alphanumeric display and a keyboard having a plurality of programmable keys, a word completion keyboard input method comprising: accepting a user keystroke from the keyboard of an input character; displaying the input character on the display; matching the input character to a dictionary of candidate words stored within the cellular telephone to select at least one candidate word in the dictionary; displaying at least one selected candidate word on the display, each selected candidate word being visually associated with a corresponding one of the plurality of programmable keys; accepting a next user keystroke from the keyboard; and if such next input keystroke corresponds to one of the plurality of programmable keys, then displaying the selected candidate word associated with such programmable key as a separate text entry on the display.
Claim 2
Dependent Claim
136 words
In a cellular telephone having an alphanumeric display and a keyboard having a plurality of programmable keys, a word completion keyboard input method comprising: accepting a user keystroke from the keyboard of an input character; displaying the input character on the display; matching the input character to a dictionary of candidate words stored within the cellular telephone to select at least one candidate word in the dictionary; displaying at least one selected candidate word on the display, each selected candidate word being visually associated with a corresponding one of the plurality of programmable keys; accepting a next user keystroke from the keyboard; and if such next input keystroke corresponds to one of the plurality of programmable keys, then displaying the selected candidate word associated with such programmable key as a separate text entry on the display.
Claim 3
Dependent Claim
19 words
The invention according to claim 1 , including automatically adding new words input by the user to the dictionary.
