Description

2297662 1 RADIO COMMUNICATION DEVICE HAVING A MOVEABLE HOUSING ELEMENT AND
KEYPAD DISPOSED THEREIN
Field of the Invention
Generally, the present invention relates to radio communication devices and more specifically to a radio communication device having a moveable housing element and a keypad disposed therein for operating the radio communication device.
Background of the Invention
Today, radio communication devices provide radio communication services such as two-way radio service, radiotelephone service, cellular phone service, cordless phone service and wireless data communication services such as wireless fax, electronic mail (e-mail), and short message service. These services are generally packaged individually into a single radio communication service device, such as a traditional radiotelephone. By packaging these radio communication services as individual devices, a manufacturer can offer a portable or hand held radio communication device that is relatively easy to use. However, there is increasing pressure in the marketplace to provide a multi - functional radio communication devise that offers more than one of the typical radio communication services mentioned above. Attempting to combine such radio communication services into a single radio 2 communication device creates a cumbersome user interface that is undesired by potential customers. A typical user interface includes a speaker, a microphone, a display and a data input device such as a keypad. For some radio communication services a small display and a small data input area is required. For example, in a portable radiotelephone often there is a small display and a fixed data input keypad. On the other hand, a wireless data service such as e-mail requires extensive display of received messages as well as extensive user data input from either a pen or a keyboard.
If a manufacturer was to provide an integrated product that combined a radiotelephone and an e-mail service, the simpler user interface of the radiotelephone service would be lost in the complex user interface required for an e-mail service. Thus, it would be advantageous to provide an integrated data communication device wherein a user could easily identify the user interface of a first data service from a user interface of a second data service.

Upon transmission of RF signals from the radio communication device 103 to the remote transceiver 101, the user interface 117 transmits user input data to the processor 115. Such data may include voice data and/or messaging information. The processor 115 formats the information obtained from the user interface 117 and transmits the formatted information to the radio circuitry 113. The radio circuitry 113 converts the formatted information into electrical RF modulated signals to the antenna 105 for transmission back to the remote transceiver 101.
In the preferred embodiment, the moveable housing element 109 has a first position and second position, also 7 referred to as an open position and a closed position. FIG. 2 is a detailed illustration of the radio communication device 103 of FIG. I in the closed position. When the moveable housing element 109 is in the closed position, it covers a portion of the touch screen display 119 and the radio communication device 103 has a limited first set of user functions available. The limited set of user functions include only radiotelephone functions such as inputting telephone numbers, initiating and ending telephone calls and recalling phone numbers from a memory. This limited set of user functions is related to the functions available on a low tier radiotelephone available today. In the closed position a portion of the touch screen display 119 is exposed to the user. This exposed portion contains a data display area 201 for displaying radiotelephone feedback such as a telephone number, a signal strength, a battery level, and roaming information. The information displayed in the data display area is oriented vertically, hereinafter referred to as a portrait mode, as illustrated in FIG. 4.
In the preferred embodiment, the moveable housing element 109 includes a keypad 125. The keypad 125 includes a plurality of individual keys including a limited number of function keys and a number pad containing individual keys numbered 0-9. Each individual key is disposed within the moveable housing element 109. Each key has a first portion of the key exposed on a first side of the moveable housing element 109 and a second portion of the key is exposed on a second side of the moveable housing element 109. The keys are arranged such that when the moveable housing element 109 is in the closed 8 position, the plurality of keys are arranged adjacent to a user data area (not shown) of the touch screen display 119. The user data area of the touch screen display 119 is covered by the moveable housing element 109 and is divided up into multiple user data sub-areas which correspond to the plurality of keys of the keypad 125. When the first portion of a first key is depressed by a user, the second portion of the first key provides a pressure against the touch screen display and activates a corresponding user data sub-area. This activation of the particular user data sub-area of the touch screen display 119 creates a corresponding signal that is sent back to the processor 115 to interpret the meaning of the activation. This signal is sent via the display bus 133.
FIG. 3 is a detailed illustration of the radio communication device 103 of FIG. 1 in the opened position. As the moveable housing element 109 is moved to the open or extended position the switch activation device 129 in conjunction with the switch 127 creates a mode change signal 131 that is sent to the processor 115, as illustrated in FIG. 1. The mode change signal 131 indicates to the processor 115 that the moveable housing element 109 is being opened and a second set of user functions becomes available to the user. In the preferred embodiment, the second set of user functions includes advanced radiotelephone control functions and messaging functions such as wireless faxing, electronic mail and short messaging service.
9 With the moveable housing element 109 in the open or extended position, the radio communication device 103 has a second set of user functions.
