Description:
CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    The present disclosure claims the priority to Chinese Patent Application No. 201410163528.0, titled “MOBILE DEVICE AND DIALING PANEL THEREOF”, filed on Apr. 22, 2014 with the State Intellectual Property Office of the People&#39;s Republic of China, which is incorporated herein by reference in entirety. 
       TECHNICAL FIELD 
       [0002]    The present disclosure relates to the field of mobile communications, and in particular to a mobile device and a dial pad thereof 
       BACKGROUND 
       [0003]    A dial pad refers to an input interface of a smart mobile device having a touch function, which is for inputting a phone number to dial before a call and performing related operations on the phone number. The dial pad is generally arranged in a lower part of a screen. The dial pad includes digit keys 0 to 9 for inputting a phone number, symbol keys asterisk (*) and pound sign (#), a backspace key and a dial key for dialing a number. In most of mobile phone systems, function keys for quickly processing a phone number, such saving the number to contacts, searching for a contact and searching for a public number, are also provided on a dial pad. 
         [0004]    With the rapid development of mobile devices with touch screens, the screens of the mobile devices are becoming bigger and bigger, causing more and more inconvenience to a user when the user is dialing a number with a single hand. In practice, digit keys, function keys and symbol keys in a dial pad are provided in a staggered arrangement, and the non-digit keys occupy favorable positions in the dial pad which are close to a finger of a user, pushing the digit keys to unfavorable positions. 
         [0005]    As a result, a movement distance for touching the digit keys by the user becomes longer, which is inconvenient for the user to quickly touch the digit keys and reduces input efficiency of the digit keys. 
       SUMMARY 
       [0006]    In view of the above, a mobile device and a dial pad thereof are provided according to the present disclosure. Dialing with the dial pad can be quicker and easier, and input efficiency of digit keys is improved. 
         [0007]    To achieve the above object, the following technical means are provided according to the present disclosure. 
         [0008]    A dial pad for a mobile device is provided, which includes a first key region and a second key region, where the first key region is for accommodating digit keys, and the second key region is for accommodating a symbol key and/or a function key. 
         [0009]    Preferably, the first key region and the second key region are rectangular regions, and the first key region is arranged at a side of the dial pad. 
         [0010]    Preferably, the digit keys 0 to 9 are arranged in a form of grids in the first key region, and sizes of the digit keys 0 to 9 are the same. 
         [0011]    Preferably, the first key region is arranged at a right side of the dial pad, and the second key region is arranged at a left side of the dial pad. 
         [0012]    Preferably, the first key region is arranged at a left side of the dial pad, and the second key region is arranged at a right side of the dial pad. 
         [0013]    Preferably, the second key region includes a mode switching key configured to switch positions of the first key region and the second key region. 
         [0014]    Preferably, the first key region further includes a dial key. 
         [0015]    Preferably, the first key region further includes a backspace key. 
         [0016]    Preferably, the second key region includes: symbol keys asterisk * and pound sign #. 
         [0017]    Preferably, the dial pad includes 4×4 grids, i.e., 16 grids, with identical sizes, the first key region includes 3×4 grids, i.e., 12 grids, and the second key region includes 1×4 grids, i.e., 4 grids. 
         [0018]    A mobile device is provided, which includes the dial pad according to any of the descriptions above. 
         [0019]    For a user using a dial pad, digit keys are frequently used keys, and symbol keys and function keys are infrequently used keys. In conventional technology, the infrequently used keys occupy favorable positions in the dial pad, and the frequently used keys are pushed to unfavorable positions. In the dial pad according to the present disclosure, frequently used keys and infrequently used keys are arranged separately. As a result, positions of the digit keys frequently used are concentrated, and a range thereof is reduced, resulting in a shorter movement distance for touching the digit keys by the user and further, improving accuracy and efficiency of dialing.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0033]    Technologies related to dial pads are studied and analyzed by the inventor. It is found that there is much to be improved for a conventional dial pad. For example, various keys in the dial pad may be arranged non-uniformly. As shown in  FIG. 1 , touch areas of keys  1 ,  4  and  7  which are distant from a finger of a user are increased, making keys in a left side easier to touch. 
         [0034]    In practice, for a user used to a standard digital panel (which does not merely refer to a dial pad, and is common in calculators, numeric keypads of computers, and keypads of bank ATMs), not only is efficiency of quick inputting not improved, but also mistakes may occur in keystrokes due to the non-uniform layout. Therefore, the inventor recognizes that the dial pad needs to be improved, to improve accuracy and efficiency of inputting for a user. In view of this, the following is provided by the inventor. 
         [0035]    The technical solutions in embodiments of the present disclosure are clearly and completely described hereinafter in conjunction with the drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a few rather than all of the embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without any creative efforts fall within the protection scope of the present disclosure. 
         [0036]    Dialing is one of the most important functions for various mobile devices such as a mobile phone, which serve as communication tools. On a smart mobile phone having a touch function, a layout of a dial pad has great flexibility, since a system can change a visual style of the dial pad and add more functions that are powerful. In addition, as screens of mobile phones are becoming bigger and bigger, it is increasingly important to design a more user-friendly and comfortable dial pad. 
         [0037]    In view of the above, a dial pad is provided according to the present disclosure. As shown in  FIG. 2 , the dial pad includes a first key region  100  and a second key region  200 . The first key region  100  is for accommodating digit keys, and the second key region  200  is for accommodating a symbol key and/or a function key. 
         [0038]    For a user using a dial pad, digit keys are frequently used keys, and symbol keys and function keys are infrequently used keys. In conventional technology, the infrequently used keys occupy favorable positions in the dial pad, and the frequently used keys are pushed to unfavorable positions. In the dial pad according to the present disclosure, frequently used keys and infrequently used keys are arranged separately. As a result, positions of the digit keys frequently used are concentrated, and a range thereof is reduced, resulting in a shorter movement distance for touching the digit keys by the user and further, improving accuracy and efficiency of dialing. 
         [0039]    In the present disclosure, the frequently used keys and infrequently used keys are arranged separately. The first key region  100  is for accommodating the frequently used keys, and the second key region  200  is for accommodating the infrequently used keys. It should be noted that “first key region  100 ” and “second key region  200 ” are merely used for purpose of distinguishing rather than representing priority in order. 
         [0040]    Preferably, the first key region  100  and the second key region  200  are rectangular regions, and the first key region  100  is arranged at a side of the dial pad. To introduce a layout of the dial pad in detail, a positional relationship between the first key region  100  and the second key region  200  is described in conjunction with the drawings. 
         [0041]    Reference is made to  FIG. 2 , which shows a positional relationship between the two key regions. The first key region  100  is arranged at a right side of the dial pad, and the second key region  200  is arranged at a left side of the dial pad. 
         [0042]    Reference is made to  FIG. 3 , which shows another positional relationship between the two key regions. The first key region  100  is arranged at a left side of the dial pad, and the second key region  200  is arranged at a right side of the dial pad. 
         [0043]    Reference is made to  FIG. 4 , which shows another positional relationship between the two key regions. The first key region  100  is arranged at an upper side of the dial pad, and the second key region is arranged at a lower side of the dial pad. 
         [0044]    Reference is made to  FIG. 5 , which shows another positional relationship between the two key regions. The first key region  100  is arranged at a lower side of the dial pad, and the second key region  200  is arranged at an upper side of the dial pad. 
         [0045]    Grids where the first key region  100  and the second key region  200  according to the above embodiments are located are of the same width or of the same height, and the positional relationship is relatively fixed. Other positional relationships between the first key region and the second key region are described hereinafter. 
         [0046]    Reference is made to  FIG. 6 , which shows another positional relationship between the two key regions. Two edges of the first key region  100  closely contact edges of the dial pad, which results in an increased area of the second key region  200  for accommodating more symbol keys or function keys. 
         [0047]    Reference is made to  FIG. 7 , which shows another positional relationship between the two key regions. One edge of the first key region  100  according to the embodiment closely contacts an edge of the dial pad. Compared with the embodiment shown in  FIG. 6 , an area of the first key region  100  is reduced, and an area of the second key region  200  is increased, which facilitates frequently using the symbol key and the function key by the user. In addition, an interface for the digit keys is relatively reduced, which improves input efficiency of the symbol key and the function key without affecting input accuracy. 
         [0048]      FIGS. 2 to 7  clearly show the position relationships between the first key region  100  and the second key region  200 . It should be noted that the areas of the first key region  100  and the second key region  200  shown in  FIGS. 2 to 7  are not invariable.  FIGS. 2 to 7  merely show relative positional relationships between the two regions without setting the areas of the two regions. 
         [0049]    In the present disclosure, the first key region is for accommodating the digit keys. Preferably, as shown in  FIG. 8 , the digit keys 0 to 9 are arranged in a form of grids in the first key region, and sizes of the digit keys 0 to 9 are the same. 
         [0050]    In the present disclosure, the digit keys 0 to 9 are arranged in a form of grids, and the sizes of the digit keys 0 to 9 are the same, i.e., the digit keys are provided in a uniform arrangement. In this way, an input habit of the user will not be changed, and an original layout of keys which is symmetrical and uniform is not broken in the present disclosure, which maintains a good visual effect. 
         [0051]    Preferably, as shown in  FIG. 9 , the first key region further includes a dial key and a backspace key. Since the user may make a mistake when dialing, the backspace key is arranged in the first key region  100 , to enable the user to delete content inputted via a key touched mistakenly. In general, after the user has inputted an  11 -digit phone number, the number is dialed via the dial key. Therefore, the dial key is arranged in the first key region  100  for convenience of dialing of the user. 
         [0052]    In the present disclosure, the second key region  200  is for accommodating the symbol key and/or the function key. 
         [0053]    The symbol key and/or the function key is arranged in the second key region  200 . That is, in the present disclosure, the second key region  200  may be provided with different interfaces for usage habits of different users. If one or more of symbol keys are frequently used by a user, the symbol keys are arranged in the second key region  200 . If one or more function keys are frequently used by a user, the function keys are arranged in the second key region  200 . Or, symbol keys and function keys which are frequently used are all arranged. It should be noted that not all keys which are frequently used can be arranged in the second key region  200 . In consideration of a size of the second key region  200 , keys may be selectively arranged in the second key region. 
         [0054]    Preferably, the second key region includes: symbol keys asterisk * and pound sign #. 
         [0055]    On the basis of the above embodiments, a specific example of the dial pad is provided according to the present disclosure. The dial pad includes 4×4 grids, i.e., 16 grids, with identical sizes. The first key region includes 3×4 grids, i.e., 12 grids, and the second key region includes 1×4 grids, i.e., 4 grids. 
         [0056]    For usage habits of different users, two modes are further provided according to the present disclosure. Reference is made to  FIG. 10 , which shows a layout of a first mode. The first key region  100  is arranged at a right side of the dial pad, and the second key region  200  is arranged at a left side of the dial pad. The first mode is applicable to a user touching a key with a right hand. 
         [0057]    Reference is made to  FIG. 11 , which shows a layout of a second mode. The first key region  100  is arranged at a left side of the dial pad, and the second key region  200  is arranged at a right side of the dial pad. The second mode is applicable to a user touching a key with a left hand. 
         [0058]    To facilitate switching of the two modes by a user, a mode switching key is provided in the second key region  200  according to the present disclosure, as shown in  FIG. 10  or  FIG. 11 . The user can switch between the first mode and the second mode by tapping the key, which provides convenience for users having different usage habits. 
         [0059]    Two specific embodiments are provided in the present disclosure, as shown in  FIG. 10  and  FIG. 11 . On the basis of the above, an application method for a dial pad is further provided according to the present disclosure. As shown in  FIG. 12 , the method includes:
