DESCRIPTION OF EMBODIMENTS
Under the condition of a handheld electronic device with a lengthened screen, an operating interface, such as a navigation button, is disposed in the lengthened area to replace traditional hardware buttons so as to reduce the volume of the handheld electronic device. At this time, as the operating interface occupies a portion of screen space and covers a frame originally displayed on the screen, this frame is to be modified appropriately, such that the user may browse the data in the original frame and operate the handheld electronic device with the operating interface. Accordingly, the present application provides a touch interface apparatus and a method of operating the handheld electronic device based on the above concept. In order to make the present application more comprehensible, embodiments are described below as the examples to prove that the application can actually be realized.
FIG. 1 is a block diagram of a touch interface apparatus according to one embodiment of the present application. Referring to FIG. 1, a touch interface apparatus 100 in the present embodiment is suitable for disposing in a handheld electronic device, such as a personal digital assistant (PDA) or a PDA phone, to operate a function module of the handheld electronic device. The touch interface apparatus 100 comprises a user interface 110 and an operating interface 120, and the functions thereof are as the following.
The user interface 110 is used to display a frame of the function module on a touch screen of the handheld electronic device when the function module of the handheld electronic device is activated. The operating interface 120 is displayed on the touch screen and provided for the user to operate when an operating function of the function module is activated.
It should be noted that in the present embodiment, when the operating function of the function module is not activated, the touch screen only displays the user interface 110 and retains a largest frame to be viewed by the user. Once the user needs to operate the function module displayed on the user interface 110, the operating interface 120 would be displayed on the touch screen. As the operating interface 120 occupies a portion of display area of the screen, a size of the original user interface 110 has to be changed. In order to retain the information displayed on the user interface 110, the present embodiment applies a proportional reduction method to display the user interface 110 on an area of the touch screen excluding the operating interface 120. As for how the touch interface apparatus 100 in the present embodiment changes the user interface 110 and the operating interface 120 accordingly based on the operating action of the user, another embodiment is used for a detailed illustration.
FIG. 2 is a flowchart illustrating a method of operating a handheld electronic device with a touch operating interface according to one embodiment of the present application. Referring to FIG. 2, the present embodiment is suitable for displaying the operating interface on a touch screen of the handheld electronic device, and providing the user to operate the handheld electronic device using this operating interface. Wherein, the handheld electronic device is, for example, a handheld electronic device comprising a touch screen, such as a PDA, and a PDA phone, etc. The following illustrates the detailed process of the operating method in the present embodiment.
First, a function module of the handheld electronic device is initiated, and a user interface of this function module is displayed on the touch screen (step S210). Moreover, the user interface has a first size. Here, the aforementioned function module is, for example, a phone book function, a multimedia player function, or a communication function included in an ordinary handheld electronic device, and is not limited thereof. Furthermore, the user interface comprises a status bar and a list page. The list page is, for example, a function menu, a song menu, a video menu, a file list, or a contact list, and comprises a plurality of data items.
For example, FIG. 3 is a user interface of a function module according to one embodiment of the present application. Referring to FIG. 3, the present embodiment uses a phone book function as an example. When the phone book function of a handheld electronic device is activated, a corresponding user interface 300 having a first size is then displayed on a touch screen. In addition to a status bar 310 on an upper portion and a menu bar 330 on a lower portion, the user interface 300 also displays a contact list 320 on a middle portion. The contact list 320 lists a plurality of data items, and each of the data items displays a name and a phone number of a contact.
When the user browses the data items in the user interface and desires to perform a corresponding operation, he/she can activate an operating function of the function module. At this moment, the handheld electronic device displays an operating interface corresponding to the function module on the touch screen (step S220). Here, the handheld electronic device displays different operating interface on the touch screen according to different function modules. For instance, if a phone book function is activated, buttons such as a navigation button, a confirmation button, or a screen button are displayed for a user to browse a contact list. If a multimedia player function is activated, then buttons such as a play button, a pause button, a stop button, a fast-forward button, or a rewind button are displayed for the user to control the playing of multimedia files. If a text message editing function is activated, keypads such as an English alphabet keypad, a Chinese phonetic symbol keypad, a numeric keypad, a T9 keypad, or a 20 key keypad are displayed for the user to input texts.
When displaying the operating interface, a size of the originally displayed user interface has to be compressed. In order to retain the content originally displayed by the user interface, the handheld electronic device then reduces the original user interface and displays the reduced user interface on an area of the touch screen excluding the operating interface (step S230), in which the reduced user interface has a second size. Wherein, the step of reducing the user interface of the function module comprises reducing the data items on a list page proportionally, such that the numbers of the data items is not changed, and the size of the reduced data items plus the size of the status bar equals the second size.
More specifically, the operating interface is, for example, displayed on one side of the touch screen, and the reduced user interface of the function module is displayed on the other side of the touch screen. For example, FIG. 4 is a schematic diagram of operating a handheld electronic device with a touch operating interface according to one embodiment of the present application. Referring to FIG. 4, the present embodiment also uses the phone book function in FIG. 3 as an example. When the phone book function of the handheld electronic device is activated, a browsing interface 400 is displayed on a lower portion of the touch screen of the handheld electronic device. Wherein, the browsing interface 400 comprises a screen button 410, a navigation button 420, and a confirmation button 430. On the other hand, the reduced user interface 300 with the phone book function is displayed on an upper portion of the touch screen (that is, an area excluding the browsing interface 400). Wherein, each of the contact information in the contact list 320 of the user interface 300 is reduced proportionally, so that the size of the reduced contact information plus the size of the status bar 310 equals the second size.
FIG. 5 is a schematic diagram of operating a handheld electronic device with a touch operating interface according to one embodiment of the present application. Referring to FIG. 5, the present embodiment uses a multimedia player function as an example. When the multimedia player function of the handheld electronic device is activated, a playing interface 510 is displayed on a lower portion of the touch screen of the handheld electronic device. Wherein, the playing interface 510 comprises a rewind button 511, a play button 512, and a fast-forward button 513. On the other hand, a reduced user interface 520 with the multimedia function is displayed on an upper portion of the touch screen (that is, an area excluding the playing interface 510). Wherein, each of the song information in a song list 522 of the user interface 520 is reduced proportionally, so that the size of the reduced song information plus the size of a status bar 521 equals the second size.
It should be noted that the handheld electronic device in the present application applies, for example, the touch screen with a WVGA resolution. So, the user interface originally displayed on the touch screen also has the WVGA resolution. After the operating interface is added, the resolution of the user interface is then reduced to an ordinary VGA resolution. The advantage of this method is that currently a plurality of software and media files still apply the VGA resolution. Thus, an area of the touch screen would be blank when executing the software or playing the media files. The present application then utilizes the area frame to dispose the navigation button or the play button on this area frame, so as to operate the handheld electronic device without affecting the execution of the software or media files. It should be noted that the present embodiment is merely exemplary and do not serve as limitations to the size of the operating interface and the reduced user interface. It will be apparent to those skilled in the art that other sizes can be selected for the operating interface and the user interface according to actual needs.
Other than the method of operating the handheld electronic device by inserting the operating interface, the present application further allows a user to switch the type of operating interface to be used as needed. Another embodiment is provided as follows to illustrate in detail.

First, a function module of the handheld electronic device is initiated, and a user interface of this function module is displayed on the touch screen (step S610), in which the user interface has a first size. When the user browses a plurality of data items in the user interface and desires to perform a corresponding operation, he/she can activate an operating function of the function module. At this moment, the operating interface corresponding to the function module is displayed on the touch screen (step S620). While displaying the operating interface, the handheld electronic device also reduces the original user interface of the function module and displays the reduced user interface on an area of the touch screen excluding the operating interface (S630), in which the reduced user interface has a second size. The detailed content of the above steps are all identical or similar to the steps S210-S230 in the above embodiment, and will not be described herein.
It should be noted that the present embodiment further comprises receiving a first key input of the operating interface and executing the corresponding operating action after displaying the operating interface and reducing the user interface. For example, after the handheld electronic device receives an input of a play button, the handheld electronic device plays multimedia files in the user interface. On the contrary, after the handheld electronic device receives an input of a stop button, the handheld electronic device stops playing the multimedia files.
In the meanwhile, the handheld electronic device in the present embodiment also receives a second key input from the operating interface and switches the displayed operating interface to another one (step S640). For example, when a user executes a phone book function and browses a contact list, the displayed operating interface is a navigation button, so as to allow the user to perform a browsing operation. At this time, if the user desires to edit one of the contact information, he/she may switch the operating interface from the original navigation button to an English alphabet keypad by pressing a switching button or executing a particular touch action on the original operating interface.
FIG. 7 is a schematic diagram of operating a handheld electronic device with a touch operating interface according to one embodiment of the present application. Referring to FIG. 3, FIG. 4, and FIG. 7 simultaneously, after a phone book function of the handheld electronic device is activated, a contact list is displayed on the touch screen (as indicated in FIG. 3). Moreover, after a browsing function of the phone book is activated, a browsing interface, comprising the screen button, the navigation button, and the confirmation button, is then displayed on the lower portion of the touch screen so as to allow the user to browse the contact information. When the user desires to edit one of the contact information, he/she may switch the operating interface from the original browsing interface to an English alphabet keypad (as an English alphabet keypad 700 shown in FIG. 7) by pressing on the operating interface area and sliding to the left or the right. Therefore, convenient operation is provided since the user may switch the operating interface to perform the operation as needed.
The present application further provides a storage medium (i.e., a compact disc, a magnetic disc, and a removable disc, etc.) that records a computer-readable authority certification so as to execute the aforementioned method of operating the handheld electronic device using the touch operating interface. Here, the authority certification program stored in the storage medium is generally composed of a plurality of program segments (i.e., an organization chart establishing program segment, an approval form program segment, a setting program segment, and a deployment program segment). Furthermore, a function of the program sections corresponds to the steps of the aforementioned method and the function block diagram of the touch interface apparatus described above.
In summary, the method of operating the handheld electronic device, the touch interface apparatus, and the storage medium in the present application utilize a property of a wide screen being longer than an ordinary screen, and dispose the touch operating interface on the lower portion of the screen so as to replace the traditional hardware buttons and reduce the handheld electronic device volume. Moreover, when activating the operating interface, the original screen frame is also appropriately modified so that the user may still view the same list content and the same amount of data items on the frame.
Although the present application has been described with reference to the above embodiments, it will be apparent to one of the ordinary skill in the art that modifications to the described embodiment may be made without departing from the spirit of the application. Accordingly, the scope of the application will be defined by the attached claims not by the above detailed descriptions.
