Lightguide subassembly for receiving a trackball navigational tool mountable within a handheld mobile deviceLightguide subassembly for receiving a trackball navigational tool mountable within a handheld mobile device description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20080074392, Lightguide subassembly for receiving a trackball navigational tool mountable within a handheld mobile device. Brief Patent Description - Full Patent Description - Patent Application Claims
CROSS REFERENCE [0001]The present application claims the benefit of U.S. Provisional Application No. 60/826,898, filed Sep. 25, 2006. Said application is expressly incorporated herein by reference in its entirety FIELD [0002]This disclosure, in a broad sense, is directed toward handheld electronic devices; and more specifically to handheld communication devices that have wireless communication capabilities and the networks within which the wireless communication devices operate. The present disclosure further relates to the lightguide subassembly which receives a navigational tool assembly and is mountable within the wireless communication device. BACKGROUND [0003]With the proliferation of wireless communication systems, compatible handheld communication devices are becoming more prevalent, as well as advanced. Whereas in the past such handheld communication devices were typically limited 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 transmissions, including even sending and receiving e-mail. Furthermore, these higher-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 functionalities necessarily require greater user interaction with the devices through included user interfaces (UIs) 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 communication 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 UIs through which users input information and control these sophisticated operations. [0004]Keyboards are used on many handheld devices, including telephones and mobile communication 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, the more important it has become to utilize the entire keyboard surface as efficiently as possible. [0005]Many keyboards on mobile devices have an input device for navigation through the graphical user interface. These interfaces include such devices as trackballs and rotating wheels which can be used to effect movement of a cursor or pointer, or to scroll up, down and about a displayed page. These navigation devices often occupy a relatively large amount of space on the incorporating mobile device. Because the navigation device is frequently used and often requires fine control, a lower end size limitation will normally be observed by device designers. To accommodate such larger, more convenient navigation devices on the housing of the mobile device, the amount of space that is available for the keys of the keyboard is correspondingly reduced if the keyboard and navigational device are proximately located to one another. [0006]Another problem is the mounting a navigation tool such as a trackball navigation tool within the wireless communication device. The location and assembly of the navigation tool has been confined to a structure that was part of the frame of the device. Thus, it is desirable to integrate the navigational tool into a subassembly.
