Mobile telephones and similar communication devices are rapidly expanding in use and function. Such devices will soon accommodate such diverse services 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.
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 keypads, button decks, and displays which provide a simple, easy to use, user interface. It is another purpose of this invention to allow the device to be operated with one hand.
A mobile communication device is designed to provide the combined functions of a personal digital assistant (PDA) and a mobile telephone. The device is constructed having a body which is defined by bottom, top, and side walls to form an enclosure which houses the internal components of the device and associated accessories. The top of the body has a recessed central portion in which a display screen panel is mounted for sliding and pivotal motion. The screen slides transverse to the longitudinal axis of the body, within the recess, between a first position in which it generally conforms to the overall contour of the body and a second position in which the screen extends externally to the body contour. In the extended position, a text keyboard, mounted on the recessed deck which forms the floor of the recessed central portion is exposed for use. On each side of the recessed central portion button decks are constructed on which can be mounted buttons or keypads suitable for the basic functioning of the communication device and its associated accessories. A digital camera is also mounted on one of the side decks on a movable bracket to accommodate video telephoning or other digital camera applications.
The display screen is viewable in either the first or second positions and may be tilted up to make viewing more convenient in the extended position. One of the side decks of the body is constructed with a telephone keypad for use with the mobile telephone function. The display may be oriented on the screen between at least two positions for reading in a longitudinal direction or a transverse direction depending on the function being used. When the text keyboard is in use the display will read longitudinally. Other functional keys are distributed on the screen panel and side decks for convenient access by the user. The mobile telephone function is designed for one hand operation.
The invention is described in more detail below with reference to the attached drawing in which:
An electronic device 30 is constructed having a configuration of screens, text keyboard, and function keys which allow the device to provide multiple functions. The configuration is optimized for utilization of internet services through a mobile telephone to provide internet access for shopping, news, email, finance, travel and other available services. In addition personal information data processing may be provided, such as calendar, appointments, notes, contacts, and other applications provided by packaged software such as MICROSOFT OFFICE. The result is the effective combination of the functions of a personal digital assistant and a mobile telephone.
The subject mobile communication device is constructed having a body 1 which is defined by bottom, top, and side walls to form an enclosure which houses the internal components of the device and associated accessories shown generally in
The screen panel 2 slides over the keyboard 12 in a direction substantially transverse to the longitudinal axis 14 of the body 1. The screen panel 2 may be mounted on pins 31, as shown in
In the alternate embodiment, shown in
The panel 2 is operable in either position and the display is oriented for the most advantageous view for a particular function. The display may be graphically rotated through 90° on screen panel 2 for reading in a transverse direction or a longitudinal direction, as shown in
In the extended position, the text keyboard 12, mounted on the recessed deck of the body 1, is exposed for use. Each side of the recessed portion of the top of the body is constructed with button decks 4 and 5 on which can be mounted buttons or keypads suitable for the basic function of the communication device and its associated accessories. A digital camera is mounted on one of the side decks on a movable bracket to accommodate video telephoning or other digital camera applications. In the alternate embodiment in which no recess is formed, a single flat deck may be formed on the top surface of the body 2. This surface may be divided into side button decks and a central text keyboard deck.
The display screen is viewable in either the first or second positions and may be tilted up, as shown in
Other functional keys are distributed on the screen panel, such as hard keys 21 which correspond to screen identified functions. The side decks 4 and 5 also provide a practical surface on which to mount frequently used function keys, such as cursor keys 13, send and end keys 9, application key 8, and on/off and display orientation or camera buttons 23 and 24 for convenient access by the user.
The mobile telephone function is designed for one hand operation. To facilitate this function the telephone number pad 7 may be arranged in a circle to provide more convenient access in both of the longitudinal or transverse positions of use. As shown in
The microphone 20 and earpiece 19 of mobile telephone 21 are positioned at the bottom surface 22 of body 1, as shown in
For further convenience a speaker 40 is provided on side deck 4 to allow hands free operation when the text keyboard is exposed for use. This enables the user to continue to work or take notes while having a telephone conversation.
In this manner a wide variety of applications can be accommodated in a very compact package with a user interface that allows convenient use of keyboard, keypads and screen. It should be noted that the applications shown in the block diagram of
