DETAILED DESCRIPTION OF THE APPLICATION
Referring to FIG. 1, a diagram of a handheld electronic device according to an embodiment of the application is shown. The handheld electronic device 100, such as a smartphone, a touch phone, or a personal digital assistant (PDA) phone, comprises a screen 110, a storage unit 120, and a processing unit 130. The screen 110 displays an entered number 112, for example “033753.” The storage unit 120 saves one or more saved numbers 121. The processing unit 130 is coupled to the screen 110 and the storage unit 120 for determining whether the entered number 112 is corresponding to one of the saved numbers 121. If the entered number 112 is not corresponding to one of the saved numbers 121, the processing unit 130 displays a save button 114 on the screen 110 for saving the entered number 112 after the save button 114 is triggered.
If the entered number 112 inputted by the user has not been saved, a save button 114 is instantly shown on the screen 110, such that the user can directly trigger the save button 114 to save the entered number 112 without using a complicated operation method.
In the present embodiment of the application, the screen 110 can be implemented by a touch screen used for displaying a keypad 116 via which the entered number 112 is inputted by a user. In another embodiment, the handheld electronic device 100 further comprises a physical keypad via which the entered number 112 is inputted by a user.
Furthermore, in the present embodiment, the user may directly click the save button 114 on the screen 110 to trigger the save button 114 to save the entered number 112. In another embodiment, the user may use a physical button corresponding to the save button 114 to trigger the save button 114. After the save button 114 is triggered, the processing unit 130 activates a number saving function to save the entered number 112.
The storage unit 120, which can be implemented by a read only memory (ROM), an additional memory card, or a subscriber identity module (SIM) card, comprises a contact list. The saved numbers 121 are corresponding to the contact data in the contact list. After the save button 114 is triggered, the processing unit 130 saves the entered number 112 as a new data of a contact in the contact list, wherein the contact data is a new contact data or a contact data previously saved in the contact list.
Generally, a telephone number will be considered as an effective telephone number when the units of digital numbers of the telephone number reach predetermined units of digital numbers, for example six units of digital numbers. In one embodiment, the processing unit 130 further determines whether the units of digital numbers of the entered number 112 reach predetermined units of digital numbers. If the processing unit 130 determines that the entered number 112 is not corresponding to one of the saved numbers 121 and the units of digital numbers of the entered number 112 reach the predetermined units of digital numbers, the processing unit 130 displays the save button 114 on the screen 110. If the processing unit 130 determines that the entered number 112 is not corresponding to one of the saved numbers 121 but the units of digital numbers of the entered number 112 are less than the predetermined units of digital numbers, the processing unit 130 does not display the save button 114 on the screen 110.
In another embodiment, after the processing unit 130 displays the save button 114 on the screen 110, the processing unit 130 further determines whether the units of digital numbers of the entered number 112 increase. If the processing unit 130 determines that the units of digital numbers of the entered number 112 increase and the entered number 112 is corresponding to one of the saved numbers 121, the processing unit 130 does not display the save button 114 on the screen 110.
For example, one of the saved numbers 121 is “033753252” and the number inputted by the user is “033753,” the processing unit 130 determines that the units of the digital numbers of the entered number 112 “033753” reach predetermined six units of digital numbers and the entered number 112 “033753” neither matches “033753252” nor matches any one of the other saved numbers 121, and then the processing unit 130 displays the save button 114 on the screen 110. However, when the user continues to input the number as “033753252,” the processing unit 130 further determines that the entered number 112 “033753252” matches the saved number 121 “033753252.” Meanwhile, the processing unit 130 does not display the save button 114 on the screen 110.
In the above embodiments, the predetermined units of digital numbers for the telephone number are six units of digital numbers, but the application is not limited thereto.
In yet another embodiment, what differs with the above embodiments is that whether the entered number 112 is corresponding to one of the saved numbers 121 is determined according to whether the entered number 112 matches a part of the saved number 121, wherein the part is, for example, the initial part, the middle part, or the final part of the saved number 121. If it is matched, the processing unit 130 does not display the save button 114 on the screen 110 even though the units of the digital numbers of the entered number 112 reach or exceed the predetermined units of digital numbers; if it is not matched, the processing unit 130 displays the save button 114 on the screen 110.
For example, one of the saved numbers 121 is “033753252” and the number inputted by the user is “033753,” the processing unit 130 determines that the entered number 112 “033753” matches a part of the saved number 121 “033753252.” Even though the units of the digital numbers of the entered number 112 “033753” reach the predetermined six units of digital numbers, the processing unit 130 does not display the save button 114 on the screen 110. When the user continues to input the number as, for example, “0337539,” the processing unit 130 further determines that the entered number 112 “0337539” does not match the saved number 121 “033753252”, and the units of the digital numbers of the entered number 112 “0337539” reach and exceed the predetermined six units of digital numbers, and then the processing unit 130 displays the save button 114 on the screen 110.
Referring to FIG. 2, an example of a flowchart of a method for saving number according to an embodiment of the application is shown. Firstly, the method begins at step S210, the entered number 112 is shown on the screen 110 of the handheld electronic device 100. The entered number 112, for example, is the number “033753” inputted by the user by pressing the keypad 116.
Then, the method proceeds to step S220, the processing unit 130 determines whether the entered number 112 is not corresponding to one of the saved numbers 121 saved in the storage unit 120. The saved numbers 121, for example, are data corresponding to a contact in a contact list.
In step S220, the method proceeds to step S230 if the entered number 112 is not corresponding to one of the saved numbers 121; or the method terminates if the entered number 112 is corresponding to one of the saved numbers 121.
Afterwards, the method proceeds to step S230, the processing unit 130 displays the save button 114 on the screen 110 for the user to save the entered number 112 by pressing the save button.
Next, the method proceeds to step S240, the save button 114 is triggered. The user can directly click the save button 114 on the screen 110 to trigger the save button 114; or the user can use a physical button corresponding to the save button 114 to trigger the save button 114.
Then, the method proceeds to step S250, the processing unit 130 activates a number saving function. After that, the method proceeds to step S260, the processing unit 130 saves the entered number 112 as a contact data.
Referring to FIG. 3, another example of a flowchart of a method for saving number according to an embodiment of the application. Firstly, the method begins at step S310, the entered number 112, for example the number “033753,” is shown on the screen 110 of the handheld electronic device 100.
Then, the method proceeds to step S320, the processing unit 130 determines whether the units of the digital numbers of the entered number 112 reach predetermined units of digital numbers, and determines whether the entered number 112 is not corresponding to one of the saved numbers 121. The predetermined units of digital numbers, for example, are six units of digital numbers.
In step S320, if the units of the digital numbers of the entered number 112 reach the predetermined units of digital numbers and the entered number 112 is not corresponding to one of the saved numbers 121, then the method proceeds to step S330; otherwise, the method terminates.
Afterwards, the method proceeds to step S330, the processing unit 130 displays the save button 114 on the screen 110. Next, the method proceeds to step S340, the save button 114 is triggered. Then, the method proceeds to step S350, the processing unit 130 activates a number saving function. After that, the method proceeds to step S360, the processing unit 130 saves the entered number 112 as a contact data.
In another embodiment, after the step S330 of displaying the save button 114 on the screen 110, the processing unit 130 further determines whether the units of the digital numbers of the entered number 112 increase. If the processing unit 130 determines that the units of the digital numbers of the entered number 112 increase and the entered number 112 is corresponding to one of the saved numbers 121, the processing unit 130 does not display the save button 114 on the screen 110.
In yet another embodiment, what differs with the above embodiments is that whether the entered number 112 is corresponding to one of the saved numbers 121 is determined according to whether the entered number 112 matches a part of the saved number 121, wherein the part is, for example, the initial part, the middle part, or the final part of the saved number 121. If it is matched, the processing unit 130 does not display the save button 114 on the screen 110 even though the units of the digital numbers of the entered number 112 reach or exceed the predetermined units of digital numbers; if it is not matched, the processing unit 130 displays the save button 114 on the screen 110.
