2. Brief Description of Related Developments
Mobile telephones and similar communication devices are rapidly expanding in use and function. Such devices will soon accommodate many diverse services such as, Internet access, personal information management, facsimile, imaging, messaging, and video conferencing, in addition to telephone communication. To accomplish this there is a need to provide keypads, function buttons, and displays that are compatible with the more complex applications to which the mobile device will be adapted. Full function text keyboards, such as the standard QWERTY typing array of keys and buttons, are difficult to provide while maintaining the compact size required in the mobile device. An equally difficult problem is presented by the need for display screens that can display the vast amount of different information that will be accessible by these devices. Such devices on the market today are cumbersome and often require several devices to obtain the full array of functions, i.e. personal digital assistant and a mobile telephone.
With the introduction of such multi-function electronic devices, it has become increasingly more difficult to design a user interface that enables the user to access the many types of functions and applications available in small hand held devices. It is a particular challenge to present a simple and efficient means by which the user can communicate with the device for browsing, selecting, and operating amidst the wide array of functional choices. The user interface generally consists of a keypad for entering data and commands and a display screen for presenting information relating to operation of the selected function. The keypad and display are in continuous competition for space on the device, as it is desirable that each be as large as possible for ease of use and viewing. This is particularly difficult when it is advantageous to provide a full function keyboard, for example, a QWERTY style keyboard.
It is a purpose of this invention to provide a keyboard mounted on a cover part to maximize the allotment of space to both the display and the keyboard.
It is a purpose of this invention to provide a simple and inexpensive full function mobile communications device which can access many services through the use of a single device. It is another purpose of this invention to combine the personal digital assistant with a mobile telephone in a practical package of minimum dimensions. It is also a purpose of this invention to provide a configuration of text keyboard and display that maximizes the size of both.
SUMMARY OF THE INVENTION
A multi-function electronic device is provided with a communication part which is adapted for independent operation as a cellular phone, personal digital assistant (PDA), and other modes, such as digital camera. A touch sensitive display provides the user interface enabling the communication part to operate on an independent basis. The communication part encloses the operational components to enable the functions provided. A cover part is constructed with a receptacle into which the communication part may be inserted. A flip up panel is pivotally mounted on the cover part to provide visual and physical access to the communication part once it is within the cover part.
In order to enhance the text input capability of the PDA function of the communication part a full text keyboard is constructed on the inside surface of the flip up panel so that it is useable for text input when open. When inserted into the cover the communication device is operatively connected to the keyboard.
In accordance with one aspect of the invention, the keyboard is pivotally mounted on the cover in a manner that allows it to be opened approximately 180° into an operational position to rest on an adjacent portion of the cover in a secure and supported position.
In accordance with another aspect of the invention, when the keyboard is in its operational position the touch screen display is visible and operates in conjunction with the full text keyboard to display text in parallel with the longitudinal axis of the keyboard. In another aspect of the invention, in this position, the display is constructed to pivot upward to provide an ergonomically convenient orientation with the keyboard.
In accordance with another aspect of the invention, the communication device may be inserted into the cover and the keyboard closed to protect the touch screen display. Windows are constructed in the cover in strategic locations to allow viewing of images and data for use in a communication or camera function.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS
A multi-functional electronic device 10, for example, a combination PDA/cellular telephone incorporating the features of the present invention is illustrated in the figures. Although the present invention will be described with reference to the embodiments shown in the drawings, it should be understood that the present invention may have many alternate forms. In addition, any suitable size, shape or type of elements or materials could be used.
The multi-functional device 10 of this invention is constructed in two parts, an independently operable communications part 1 and a cover part 2, as shown in FIGS. 1 and 2. Communications part 1 encloses the components of the device in various known configurations to provide a wide variety of functions and applications. These components include, for example a microprocessor, mobile telephone transceiver, PDA, display driver firmware, memory and other processor components depending on the features offered to the user. In the preferred embodiment these features include a mobile telephone, a PDA, and a camera. The communications part 1 is constructed with a touch screen display 3 and interface keys and buttons 4 for operation of the camera feature, power on/off, and other basic functions. The touch sensitive screen 3 may be configured to provide the user interface for the PDA and telephone features.
The cover part 2 is constructed with a base 5 having a receptacle 6 for receiving the communications part 1. As shown in FIG. 3, cover part 2 has a flip up lid 7 pivotally connected to the base by hinges 8, adjacent to the receptacle 6. The lid 7 is moveable between a position in which the lid extends at least partially over the receptacle and an open position in which the lid 7 rests on a flat deck 9 at the rear of the cover 2. The receptacle 6 includes an opening 20 that allows insertion of communication part 1 independent of the position of the lid 7. A full text keyboard 11 is mounted on the inside face 12 of lid 7 relative to the cover position. The keyboard 11 is accessible in the fully opened position of the lid 7 and is securely supported by deck 9.
Since the operational components of the multi-function device 10 are contained in the communications part 1, an electrical connection is provided when the communication part 1 is engaged in cover part 2. This enables the keyboard 11 to be fully operationally in conjunction with touch screen display 3.
In an alternate embodiment, communication part 2 is engagable in the cover position in two operational positions, one, a fully inserted position, as shown in FIG. 4, or a pivoted position, as shown in phantom in FIG. 4. In the fully inserted position, the display screen 3 may not be fully visible and the display portion is therefore limited to a certain extent. In the pivoted position (see phantom lines 13), the touch screen display may be tilted upward to provide an ergonomic orientation, for example at angle θ of 100° to 170°. In this position, the display 3 is fully exposed and can be configured to provide a full display for keyboard 11. In this manner the space allotment for the keyboard and display in a multi-functional device is maximized within the limits of the device without compromising the functioning of either component.
In an alternate embodiment of this invention, window 14 may be constructed in rear deck 9 to provide visible access to a portion of display screen 3. The display 3 may be configured to provide a display interface for a camera or cellular phone feature, thereby enabling these features to be used without removing part 1 from the cover part 2.
In operation, as shown in FIG. 5, the multifunction communication terminal 10 of FIGS. 1-4, comprises a system of components that are operatively interconnected through main controller 15 to provide the combined functions of a camera 16, PDA 17, and mobile telephone 18. Main control processor 15 is supported by a memory 19 and processes data and commands from mobile telephone module 18, camera module 16, and PDA module 17, and other user interface components. The primary user interface of the device 10 includes touch sensitive display 3 and function keys and buttons 4. The display 3 has an associated driver 21. Touch sensitive display screen 3 is operable to support data input for PDA functions, for example in association with keyboard 11, and a data or image display mode to support other functions. Browser key and soft keys 4 provide a secondary user interface as needed. Controller 15 provides the operating function of the PDA 17 and coordinates the operation of the keyboard 11 with the display screen 3.
Display driver 21 is operatively associated with display screen 3 to cause the displayed data to be oriented longitudinally on the display screen 3, in parallel with the keyboard 11. Insertion of communication part 1 in cover part 2 prompts controller 15 to activate the keyboard 11 and cause display driver 21 to orient the displayed data accordingly. The size of the display area would also be coordinated according to the available space for the different engagement positions, i.e. full insertion, or pivotal, of communication part 1 in the cover part 2. In addition, the display area would be configured to conform with the area of display 3 exposed by window 14, when the communication part 1 is fully inserted and the lid 7 is closed.
It should be understood that the above description is only illustrative of the invention. Various alternatives and modifications can be devised by those skilled in the art with out departing from the invention. Accordingly, the present invention is intended to embrace all such alternatives, modifications and variances which fall with the scope of the appended claims.
