Description

NAVIGATION KEY FOR USE IN MOBILE COMMUNICATION TERMINAL AND A MOBILE COMMUNICATION TERMINAL

COMPRISING THE SAME

TECHNICAL FIELD

The present invention relates to a navigation key for use in a mobile communication terminal such as a mobile phone, and more particularly, to a hemispherical navigation key and a mobile communication terminal comprising the navigation key; when a user's finger slides on a hemispherical surface of the navigation key, a touch panel disposed on the hemispherical surface acquires a movement track of the finger and produces a displacement signal.

BACKGROUND OF THE INVENTION

A mobile communication terminal such as a mobile phone is usually provided with a navigation key, for moving a cursor on a screen of the mobile communication terminal, and selecting a specific object, such as a menu.

When designing the navigation key in the mobile communication terminal, two methods are usually adopted. One method is to design four direction keys (leftward, rightward, upward and downward) and a center control key; the direction keys are used to move the cursor and the control key is used to "confirm" an operation; such navigation key is usually designed as planar. The other method is to use a joy stick, which is commonly cylindrical, slim and small; but the user often feels that the hand feel is poor, and the operation is not convenient.

In addition, the navigation key designed in any of the above two methods still has the following problem. As the screen of the mobile communication terminal tends to be designed larger and larger, when the overall dimension is fixed, a large screen surely reduces the area of the navigation key and the number keys. Thus the actual operation is not convenient for the user; especially during sending a short message, the navigation key is frequently used to select characters, and a small navigation key will affect the input speed. As time passes, the user will have a bad impression on the brand of the currently used terminal.

SUMMARY OF THE INVENTION

The present invention is provided in view of the above problem in the prior art. An aspect of the invention is to convenience the user's operation by improving the design of the navigation key, so as to provide a mobile communication terminal more conveniently to be operated.

In details, the present invention adopts a hemispherical navigation key, by integrating the leftward, rightward, upward and downward keys and the intermediate control key together. The user only needs to press his thumb or other fingers on the surface of the hemispherical navigation key, and slides in a desired direction to position at any direction.

In one aspect of the present invention, a navigation key for use in a mobile communication terminal is provided, wherein the navigation key is configured in a hemispherical shape, and a touch panel is disposed on a hemispherical surface of the navigation key, when a user's finger slides on the hemispherical surface of the navigation key, the touch panel acquires a movement track of the finger and produces a corresponding displacement signal.

Several other aspects of the invention are sumarized just below.

The above navigation key is further configured to control a cursor on a display screen of the mobile communication terminal to move in various directions on the display screen.

The above navigation key is further configured to perform a selection or confirmation operation on a specific object on the display screen, or perform a photographing operation with a digital camera, when the navigation key is fully pressed.

The above navigation key is further configured to focus on an object when the navigation key is half-pressed and in a photographing state, or scroll the display screen in response to the produced displacement signal, when the navigation key is half-pressed and in a non-photographing state and the user's finger slides on the hemispherical surface of the navigation key at the same time.

The above navigation key is further configured to control an orientation of the camera comprised in the mobile communication terminal.

The above navigation key is further configured to be used as a control key for controlling a game when small games in the mobile communication terminal are run.

In another aspect of the invention, a mobile communication terminal comprising the above navigation key is further provided.

These and further aspects and features of the present invention will be apparent with reference to the following description and attached drawings.

DETAILED DESCRIPTION OF THE INVENTION

The interchangeable terms "electronic equipment" and "electronic device" include portable radio communication equipment. The term "portable radio communication equipment", which hereinafter is referred to as a "mobile radio terminal", as "portable electronic equipment", or as a "portable communication device", includes all equipment such as mobile telephones, pagers, communicators, electronic organizers, personal digital assistants (PDAs), smartphones, portable communication apparatus or the like.

In the present application, embodiments of the invention are described primarily in the context of a portable electronic device in the form of a mobile telephone (also referred to as "mobile phone"). However, it will be appreciated that the invention is not intended to be limited to the context of a mobile telephone and may relate to any type of appropriate electronic equipment, examples of which include a media player, a gaming device, PDA and a computer, digital cameras, etc.

As is shown in Figs. 1 and 2, the present invention includes a hemispherical spatial navigation key 10, so that the area of the navigation key in the mobile communication terminal 11 is expanded, and the keys 12 are positioned more compactly and beautifully.

In details, as shown in Figs. 1 and 2, a hemispherical navigation key 10 is configured to replace the common navigation key, in a mobile communication terminal 11 , and a touch panel 13 is disposed on a hemispherical surface 14 of the navigation key 10. The concrete construction and circuit of the touch panel 13 may be similar to a touch panel used in a conventional notebook computer.

In a portable device such as a notebook computer, a touch panel is commonly used to replace an input device of a mouse type. The touch panel includes a press-sensing board or touch-sensitive surface that senses a movement track of a user's finger. When the user's finger moves on the touch panel, a cursor will move correspondingly on the display screen, so as to complete a positioning operation.

The size of the mobile communication terminal is much smaller than a notebook computer. If a planar type touch panel is used in a mobile communication terminal such as a mobile phone, a high positioning accuracy cannot be achieved due to limited area of the touch panel, or the area of the screen or other press keys will be reduced, or the size of the entire terminal will have to be increased unacceptably.

However, in the present invention using a hemispherical navigation key 10 with a touch-sensitive touch panel 13, when the user's finger slides on the hemispherical surface 14 of the navigation key 10 while touching the touch panel 13, the touch panel acquires a movement track of the finger and produces a corresponding displacement signal.

In an embodiment, the navigation key 10 is configured to control a cursor 15 on a display screen 16 of the mobile communication terminal 11 to move in a corresponding direction on the display screen, according to the produced displacement signal.

In an embodiment, the navigation key 10 of the present invention has a full-pressed state and a half-pressed state, similar to a focusing and photographing button in a digital camera. When the navigation key 10 is full-pressed, it is possible to perform a selection or confirmation operation on a specific object on the display screen 16, or perform a photographing operation with the digital camera 17a or 17b. While when the navigation key 10 is half-pressed and the user is in the photographing state, it is possible to focus on a subject; or if the user is in a non-photographing state and the user's finger slides on the touch panel 13 of the hemispherical surface 14 of the navigation key 10 at the same time, it is possible to scroll the display screen 14 in response to the produced displacement signal. This is very convenient when the contents are displayed on more than one page of screen. For example, when the mobile communication terminal 11 is used to read emails or other documents, or surf on the Internet, such function will bring great convenience.

In an embodiment, when the mobile communication terminal 11 is provided with a camera 17a or 17b, and particularly, a camera for video conversation during which the camera 17b is facing the user, the navigation key 10 of the present invention is configured to control the orientation of the camera 17b, so that the camera faces the user in a more appropriate angle and the partner in the video conversation can better watch the user. For China where the 3 G communication network is going to be applied, and the countries having been covered under the 3 G network, this is a very convenient operation when carrying out a video conversation.

Furthermore, many games can be presently installed in the mobile communication terminal 11 , and these games commonly need an operation button that can conveniently move the cursor or switch the direction. The navigation key 10 of the present invention is suitable to be used as the operation key for these games, so that the user can operate more accurately, and hence promote the operation agility degree and responding speed.

The hemispherical navigation key 10 of the present invention is described as above in conjunction of concrete application examples. However, persons skilled in the art should be clear that, the applications of the hemispherical navigation key 10 of the present invention are not limited to the above examples. The purpose of the hemispherical navigation key 10 of the present invention can be further extended by combining the existing applications of the mobile communication terminal 11 and the new applications to be developed in the future.

Briefly turning to Fig. 4, a schematic block diagram of the operating circuitry or system of the mobile phone 11 is illustrated. The illustration is exemplary; other types of circuitry may be employed in addition to or instead of the operating circuitry to carry out telecommunication functions and other functions. The operating circuitry includes a controller 30 (sometimes referred to as a processor or as an operational control and may include a microprocessor or other processor device and/or logic device) that receives inputs and controls the various parts and operation of the operating circuitry. An input module 31 provides inputs to the controller 30. The input module includes the camera 7 (7a, 7b), a display controller 32, and a keys input module 33. The camera may include a lens, shutter, image sensor 7s, e.g., a digital image sensor, such as, for example, a CCD (charge coupled device), a CMOS device, or another image sensor. Images that are sensed by the image sensor may be provided the controller 30 for use in conventional ways, e.g., for storage, for transmitting, etc.

The display controller 32 responds to inputs from a touch sensitive display 16 or from another type of display that is capable of providing inputs to the controller. Thus, for example, touching of a stylus or a finger to a part of a touch sensitive display, e.g., to select a song in a displayed list of songs, to select a contact in a displayed list of contacts, to select an icon or function in a GUI shown on the display may provide an input to the controller in conventional manner. The display controller 32 also may receive inputs from the controller 30 to cause images, icons, information, etc., to be shown on the display 16. The keys input module 33, for example, may be the keys 12 themselves and/or may be signal conditioning, decoding or other appropriate circuitry to provide to the controller 30 information indicating the operating of one or more keys 12 in conventional manner.

A memory 34 is coupled to the controller 30. The memory may be a solid state memory, e.g., read only memory (ROM), random access memory (RAM), SIM card, etc. Memory that maintains information even when power is off and that can be selectively erased and provided with more data, an example of which sometimes is referred to as an EPROM or the like. The memory may be some other type device. The memory 34 includes a buffer memory 35 (sometimes referred to herein as buffer). The memory 34 may include an applications or functions storing section or function 36 to store applications programs and functions programs or routines for carrying out operation of the mobile phone 11 via the controller 30. The memory 34 also may include a data storage section or function 37 to store data, e.g., contacts, numerical data, pictures, and/or virtually any other data for use by the mobile phone 11. A drivers section 38 of the memory 34 may include various drivers for the mobile phone 11, for communication functions and/or for carrying out other functions of the mobile phone.

The mobile phone 11 includes a telecommunications portion 40. The telecommunications portion 40 includes, for example, a communications module - transmitter/receiver 41 that receives incoming signals and transmits outgoing signals via antenna 41a. The communications module — transmitter/receiver 41 is coupled to the controller 30 to provide inputs to and to receive output signals, as may be the case in conventional mobile phones. The communications module - transmitter/receiver 41 also is coupled to the speaker 42 and microphone 43 via an audio processor 44 to provide audio output via the speaker and to receive audio input from the microphone for usual telecommunications functions. The speaker and microphone enable a user to listen and to speak via the mobile phone 11. The audio processor 44 may include any appropriate buffers, decoders, amplifiers and the like.

The mobile phone 11 also includes a power supply 45 that may be coupled to provide electrical power to the operational circuitry 3 upon closing of the on/off switch 46.

For telecommunication functions and/or for various other applications and/or functions as may be selected from a GUI, the mobile phone 11 may operate in a conventional way. For example, the mobile phone may be used to make and to receive telephone calls, to play back songs, pictures, videos, movies, etc., to take and to store photographs or video, to prepare, to save, to maintain, and to display documents and databases such as a contacts or other database, to browse the Internet, to maintain a calendar, etc.

In operation of the mobile communication terminal 11 using the hemispherical navigation switch 10, a user may turn on the power switch 46 to provide power from the power supply 45; and the user may press the navigation switch 10 part way or fully or not at all; and the user also may move his or her finger over the touch sensitive surface 14 along the hemispherical surface 13 to provide input to the controller, as is illustrated in the drawings. As the navigation switch 10 is pressed or is not pressed and a the finger is moved on the surface thereof, respective signals are provided to the controller 13 to cause appropriate response from the mobile communication terminal 11, e.g., in a communication mode, in a mode to select a respective icon or item in a list shown on the display 16, to play a game, etc.

It will be appreciated that portions of the present invention can be implemented in hardware, software, firmware, or a combination thereof. In the described embodiment(s), a number of the steps or methods may be implemented in software or firmware that is stored in a memory and that is executed by a suitable instruction execution system.
