BACKROITND
[0004] With the proliferation of wireless communication
systems, compatible
handheld electronic devices are becoming more prevalent, as well as advanced.
Whereas
in the past such handheld electronic devices were typically lirnited to either
voice =
transmission (cell phones) or text transmission (pagers and PDAs), today's
consumer
often demands a multifunctional device capable of performing both types. of
trans.missions, including even sending and receiving e-mail. Furthermore,
these higher-
= 10 performance devices can also be capable of sending and receiving other
types of data
including that which allows:the viewing and use of Internet websites. These
higher level
iimctionalities necessarily require greater user interaction with the devices
through
included user interfaces (Ills) -which may have originally been designed to
accommodate
making and receiving telephone calls and sending messages over a related Short
. Messaging Service (SMS). As might be expected, suppliers of such mobile
electronic
devices and the related service providers are anxious to .meet these customer
requirements, but the demands of these more advanced functionalities have in
many
circumstances rendered the traditional user interfaces unsatisfactory, a
situation that has
caused deSigners to have to improve the tfis through which users input
information and
control these sophisticated operations.
[0005] Keyboards. are used on many handheld devices,
including telephones and
mobile electronic devices. The size of keyboards has been reduced over the
years, as
newer, smaller devices have become popular. Cell phones, for example, are now
sized to
fit in one's pOcket or the palm of the hand. As.the size of the devices has
decreased, it
has become more important to utilize the entire - keyboard surface as
efficiently as

possible. Thus, a need exists for a handheld electronic device which can be
operated
easily from a device perspective and a data entry perspective.

When equipped for twO-way communication, the handheld electronic
device 300 also features a communication subsystem 311 as indicated in FIG. =
3. The
communication subsystem 311 can modified so that it can support the
operational needs
.of the handheld device 300. As shown in FIG. 3, the subsystem 311 includes =
a
5
transmitter 314 and receiver 312 including the associated antenna or antennae
316, 318 as
described above, local oscillators (L0s) 313, and a processing module 320
which in the

[0035] If the han.dheld electranic device 300 is enabled as described
above, or the

exemplary embodiment is equipped with an integral or internal antenna 318 for
transmitting signals to the communication network 319. Likewise the handheld
electronic device 300 in the presently described exemplary embodiment can be
equipped =
with another antenna 316 for receiving communication from the cornmunication
network
319. These antennae 316, 318 in another exemplary embodiment can be combined

calendars. For each =
such application, synchronization with home-based versions on the applications
can be
critical for either or both of their long term and short term utility. As an
example, emails

Address book entries, on the 'other hand, can be usually updated less
frequently without
inconvenience. Therefore, the utility of the handheld device 300 can be
enhanced when .
connectable within a communication system, and particularly when connectable
on a
wireless basis in a network 319 in which voice, text messaging, and other data
transfer
are accommodated. The auxiliary I/0 subsystem 328 of FIG. 3 can take .the form
of a
variety of different navigation tools. (multi-directional or single-
directional) such as a
navigation tool 327 with trackball = assembly 321 as illustrated in the
exemplary
embodiment shown in FIG. 2, or a tkunbwheel, a navigation.pa.d, a joystick, or
the like

tools are located
. on the front surface of the handheld device 300 when in an open
configuration 601 bat
can also be located on any exterior surface of the. handheld device 300. Other
auxiliary
I/0 subsystems can include external display devices and externally connected
keyboards

=
[0040] One of the important aspects of the handheld
electrdnic device 300 to which
this disclosure is directed is its size. While some users will grasp the
handheld device
300 in both hands when entering text as in FIG. 2A, it is also possible for
users to cradle
= the handheld device 300 in one hand in such a manner that inPut and
control over the
handheld device 300 can be effected using the thumb of the same hand in which
the
= handheld device 300 is held. However, it is appreciated that additional
control can be
effected by using both hands_ As a handheld device 300 that is easy to grasp
and
= 20 desirably pocketable, the size of the handheld device 300 must be kept
com,mensurately
- small. Of the device's dimensions, limiting its width is important for the=
purpose of
= = assuring
cradleability in a user's hand. . . . . . .
[0041] However, some users can find it difficult to operate
because of the reduced
size. The dual-hinged intercormector 80 gives an increase in 'surface area and
a
protruding surface to grasp as well. The extended nature of the dual-hinged .
interconnector 80 allows the clam-shell style handheld electronic device 300
to be held
= between the fingers of both hands. Thus, the interconnector can act as a
handle of sorts.

=
= 14
Moreover, this configuration enhances stability and hence makes thumb
attivation of the
keys on keyboard housing 640. =
[0042] = Additionally, the small size of the handheld device
300 can be a drawback
in that there is limited exterior surface area for the inclusion of user input
and device
output features. This is especially true for the "prime real estate" on the
face of the
keyboard: housing .640 of the handheld device 300 in the open configuration
601_
Furthermore, as shown in the embodiment of FIG. 2A, the display screen 322 is
located
above a keyboard 650 :that is utilized for data entry into the handheld device
300 by the
user, and above a navigation tool 327 which is located on the interior surface
of the dual-
hinged interconnector. If the screen 322 is provided below the keyboard 650, a
=problem =
occurs in that viewing the screen 322 is inhibited when the useris inputting
data using the
keyboard 650. Therefore, in the embodiment shown in FIG. 2B, the display
screen 322= is
above the navigation row 70 and keyboard 650, thereby Solving the problem by
assuring
that the hands and fingers do riot block the view of the screen 322 during
data .entry
periods. This property is enhanced by the fact that the angle between the
interior surface
of the keyboard housing .640 and the interconnector 80, and the angle between
the
= interconnector 80 and the display face 320 can each. take separate
values, and thus more
positional options exist for the user.
= =
[0043) Another positional option for the user is to set the
device down 300
temporarily, as in FIG. 2B (and also FIG. 15). = If the user places the device
on. a fiat - = =
surface a user Can derive a benefit from being able to view the display screen
322 without
having to lift the device 300 by hand. As can be seen from FIG_ 2B, the dual-
hinged
interconnector 80 can act as a stand which props up the display housing 95.
Because they
are connected via hinges, the angle Ai between the display housing 95 and the
keyboard
= housing 90, the angle A2 between the back of the interconneotor 81 and
the display

all adjusvable. This adjustability, coupled With the stand action of the
interconnector, 80
Means that a user will be able to adjust the display screen 322 for
maintenance of visual
contact while the device 300 is in a resting orientation 303.

housing 90 could be constructed in various proportions within this disclosure.
=[0046] A closed configuration 600 from the right side is also shown FIG.
10.
Although it is compact, the device 300 has multiple input and output
faculties, even *hen
inthe closed configuration 609. For example, a programmable key 120, a
universal serial
bus port 874 and a. headset jack 875 are shown op the exterior of the device
300 on the
" display housing. Those skilled in the art will appreciate that the
programmable keys of
the device 105, 120 can be programmed to have multiple functions, allowing the
keys to
activate a camera, act as an alternate mute button, a function cancel button,
among other
= things. In =at least one example as illustrated in FIG. 10, some portion
of the keyboard
650 can be igen between the keyboard housing 90 and display housing 95. In
another .
.possible embodiment the device 300 could be so configured so as to completely
conceal
the keyboard 650 when viewed from the same side as in FIG_ 10 while still
coming
15. within this disclosure. Also, the dual-hinged interconnector 80 can be
seen between and
= above the hinge-end covers 900 in the illustrated.example. In the
embodiment pictured in
= FIG. 10, the thickness of the interconnectcir TT is equal to the combined
thickness of the
display housing 95 and the keyboard housing 90. The connectors could be
located on the =
sides of the interconnector 80 closest to the housings 95, 90 and parallel to
the lengthwise
axis, or on the sides which are closest to the housings 95, 90 but
perpendicular to said
= axis. .
(0047] The other side view of the device 300 in a closed
configuration 600 is
shown in FIG. 11. Even though the embodiment- is streamlined and compact,
multiple
input and output options exist. For example, in the embodiment of FIG..11, the
volume =
buttons or keys 100 in the keyboard housing 90 are situated next to a user-
progtammable
key 105. The volume buttons or keys can be configured so as to adjust the

FIG: 11 shows the dual-hinged
= = interconnector 80 between and above two hinge-end covers 900. As will
be described
further herein, still other input and output options can be provided on the
exterior of the
device 300. Again, as will be appreciated by those in the art; while a
particular shape is
shown, others are possible while still falling within the present disclosure,
for example
