BACKGROUND
1. Field
The present disclosure is generally directed to a mobile communication device.
More particularly, the present disclosure is directed to a dual input user interface for a
mobile communication device.
2. Description of Related Art
Presently, mobile communication devices, such as cellular telephones, are
becoming a common means of communication. For example, a mobile
communication device can include a telephone keypad that a user actuates to place a
telephone call to a friend. The user may also use toe mobile communication device to
send text messages to the friend. For example, alphanumeric characters are often
assigned to a specific number of presses of specific numeric key. Thus, the user can
perform text entry on a telephone keypad by pressing a numeric key a specific number
of presses to obtain a desired alphanumeric character.
Unfortunately, pressing numeric keys numerous times for a specific character
is inconvenient for the user. For example, numerous keypresses increases the amount
of time necessary to compose a text message. The numerous keypresses also requires
additional concentration by the user to keep track of the number of presses. The
numerous keypresses further requires the user to frequently check a display to
determine if the appropriate character has been entered.
Thus, there is a need for an mobile communication device that can provide for
more convenient text entry functionality along with portable phone functionality.

display, a plasma display, or any other means for displaying information. The second
display 230 can display at least one line of text, only one line of text, two lines of text,
text and graphics, or any other data. The text keypad 240 can be a QWERTY
typewriter-style keypad or any other text input keypad. The text keypad 240 can also
be a button keypad, a keypad displayed on a display that uses sensors for text entry, a
pressure sensitive touch pad, a touch screen, or any other means for inputting text.
In operation, the second face side 220 can be used for entering text. For
example, the text keypad 240 can be used for ease of entering text of a text message.
The second display 230 can be used to view messages being entered, stored messages,
and received messages. The second display 230 may also be used to provide status,
menu, and selection indications. The input lock button 160 can be used to selectively
lock and unlock input functionality of the user interface 140, the mobile
communication device input devices 147, the numeric keypad 145, and/or the text
keypad 240. For example, the input lock button 160 can disable the user interface 140 .
and/or the numeric keypad 145 to allow for placement the mobile communication
device 100 on a table for text entry on the text keypad 240 without activating the
numeric keypad 145. The input lock button 160 can also disable the text keypad 240
when the mobile communication device 100 is used as a portable phone. The input
lock button 160 can additionally disable various combinations of both the user
interface 140 and me numeric keypad 240 for placing the mobile communication
device 100 in a pocket or purse. This functionality may also be performed in a menu
or using a soft key associated with an icon on a display. The mobile communication

device 100 may also include a speakerphone for audible communications while
inputting text on the text keypad 240.

second face side 320 can include a second display 330, a third display 335, and a text
keypad 340. Similar elements operate in a similar manner to those disclosed above.
Also, the third display 335 can be used to display additional text or graphics. For
example, the third display 335 can display additional text of a message. Also, the
third display 335 can display message status information, header information, sender
information, or any other useful information. The third display 335 can display one
line of text, multiple lines of text, or combinations of text and graphics.
Fig. 4 is an exemplary illustration of a second face side 420 of a housing 410
of a mobile communication device 400 according to another embodiment. Similar
elements can operate in a similar manner to those disclosed above. The second face
side 420 can include a second display 430 and a text keypad 440. The second display
430 can substantially surround the text keypad 440. For example, the second display
430 can completely surround or partially surround the text keypad 440. The second
display 430 can display text with the bottoms of characters always oriented towards
the center of the face side 420. The second display 430 can also display text with the
bottoms of characters always oriented towards a selected side of the second face side
420. For example, the second display 430 can display text with the characters in
alignment with the text keypad 440. The second display 430 can additionally
statically display text or can scroll text around the text keypad 440.

include any combination of a transmitter and/or a receiver. The user interface 540 can
include a numeric keypad, a text input device, an input lock button, or any other
mobile communication device input devices. The memory 560 can store program
codes and data. Many of the components of the mobile communication device 500
can be contained in a housing such as the housing 110. In operation, the controller
510 controls the operation of the mobile communication device 500. For example, the
controller 510 can receive signals from the user interface 540 and can activate and
deactivate input devices based on signals received from the user interface 540. The
controller 510 can also control the display of information on the display 530. For
example, the controller 520 can control text orientation and movement on the display
530.
The controller 510 of this invention is preferably implemented on a
programmed processor. However, the controller 510 may also be implemented on a
general purpose or special purpose computer, a programmed microprocessor or
microcontroller and peripheral integrated circuit elements, an ASIC or other integrated
circuit, a hardware electronic or logic circuit such as a discrete element circuit, a
programmable logic device such as a PLD, PLA,FPGA or PAL, or the like. In
