FIG. 1 illustrates a block diagram of an illustrative embodiment of a computer device 10 that allows users to utilize different forces in place of the conventional pointing device. Particularly, the computer device 10 may have a touch screen 102, a processor 104, a pointing device 106 such as a mouse or track ball, and an operating system 108.
The basic configuration of the computer device 10 can refer to the computer product of ASUSTM T91 Table or AcerTM 420P-232G32n, or other computer product, wherein an example of the operating system 108 thereof can be MicrosoftTM Window 7TM.
Specifically, the touch screen 102 of the illustrative embodiment may be a resistive type touch screen that can sense the touch pressure applied by the user. With regard to the details of touch-sensing of the resistive type touch screen, those skilled in the art can refer to the article titled “Pressure-based text entry for mobile devices” by Stephen A. Brewster and Michael Hughes, which is incorporated herein by reference with its entirety.
FIG. 2 illustrates a flowchart of an illustrative method for operating the computer device 10 in one embodiment.
Step 200: the operating system 108 may pre-define a first pointing device command and a second pointing device command, wherein the first pointing device and the second pointing device command may be irrelevant to directional pointing control. Various applications executed on the operating system 108 can run different processes in response to the first pointing device command and the second pointing device command, respectively. For example, in a file management application, the first pointing device command executed with respect to a file may be to open the file, while the second pointing device command executed with respect to the file may be to call the function menu for the file.
Step 202: the user may operate the pointing device 106 to generate a first pointing device signal, and in response to the first pointing device signal, the processor 104 may invoke the pre-defined first pointing device command. For example, the user may double-click the left mouse button on the icon of a file (i.e. a graphic object) to generate a mouse double-click signal. The processor 104 may then invoke the pre-defined first pointing device command (i.e. the double-click command) to open the file.
Step 204: the user may operate the pointing device 106 to generate a second pointing device signal, and in response to the second pointing device signal, the processor 104 may invoke the pre-defined second pointing device command. For example, the user may double-click the right mouse button on the icon of a file to generate a right button signal. The processor 104 may then invoke the pre-defined second pointing device command (i.e. the right button command) to call the function menu for the file.
In addition to operations of the pointing device 106, the user can utilize the resistive type touch screen to perform operations.
Step 206: in response to a first touch, the touch screen 102 may generate a first touch signal, and in response to the first touch signal, the processor 104 may invoke the first pointing command. For example, the user may touch the icon of the file by a relatively smaller force to generate a first touch signal. The processor 104 may then invoke the pre-defined first pointing device command (i.e. the double-click command in Step 202) to open the file.
Step 208: in response to a second touch different from the first touch, the touch screen 102 may generate a second touch signal, and in response to the second touch signal, the processor 104 may invoke the second pointing device command. For example, the user may touch the icon of the file by a relatively larger force to generate a second touch signal. The processor 104 may then invoke the pre-defined second pointing device command (i.e. the right button command in Step 204) to call the function menu for the file. It is noted that any pressure applied by the user may be applicable to the present invention provided that the pressures given by the user in step 206 and step 208 can be distinguished by the touch screen 102. The value of pressure applied by the user is not limited in the described embodiments.
The present invention can also have other modifications. For example, during steps 202-208, the location of the file icon can be constant or variable and not limited in the described embodiments.
Furthermore, the first pointing device command and the second pointing device command are not necessarily associated with a specific graphic object. For example, in one application, processes irrelevant to the graphic object can be set in response to the first pointing device command and the second pointing device command, respectively. For example, when the user double-clicks on any location of the operating area or lightly touches the touch screen, the application may run as background. When the user hits the mouse right button on any location of the operating area or relatively heavily touches the touch screen, the application may be ended.
FIG. 3 illustrates a computer device 30 for multimedia file browsing application in one illustrative embodiment. Particularly, the computer device 30 may have a touch screen 302, a processor 304, and a multimedia file browsing application 306. The basic configuration of the computer 30 may refer to AppleTM iPhoneTM or NokiaTM N800 Internet Tablet, or other computer device, wherein an example of the operating system used in the computer device 30 can be Apple iOS, or Nokia Maemo, or Google Android and not limited to the described embodiments.
It is noted that the touch screen 302 is not limited to resistive type and can be inductive type, surface acoustic type, or optical type.
FIG. 4 illustrates a flowchart of an illustrative method for operating the computer device 30 in one embodiment.
Step 400, the multimedia file browsing application 306 may be executed. The multimedia file browsing application 306 may provide the user with a first browsing mode and a second browsing mode. In the context of the present invention, different browsing modes may mean that the user can browse the content of the multimedia file by different ways, and under different browsing modes, same or different commands can be used for browsing the multimedia file. For example, the application 306 can be a reading program of an electronic book and can provide the user with vertical read mode and horizontal read mode, or page locking mode and page drag-able mode, or read-only mode and highlight and notation mode, or full page mode and column mode.
The application 306 also can be a photo-browsing mode to provide full screen mode or partial view mode.
The application 306 also can be a video-playing mode to provide Chinese subtitle mode or English subtitle mode or no subtitle mode.
The application 306 also can be an audio-playing program to provide normal mode or fast forward mode.
The electronic book read program together with vertical read mode and horizontal read mode thereof will be described below as an illustrative embodiment of the present invention.
Step 402: in the vertical read mode of the electronic book read program 306, the user can perform a first touch on the book page presented on the touch screen 302, and the touch screen 302 may correspondingly generate a first touch signal. In response to the first touch signal, the processor 304 may invoke a browsing command in the vertical read mode, such as jump to next page.
Step 404: in the vertical read mode of the electronic book read program 306, the user can perform a second touch different from the first touch of step 402 on the book page presented on the touch screen 302, and the touch screen 302 may correspondingly generate a second touch signal. In response to the second touch signal, the processor 304 may invoke a switching command to switch the vertical read mode to the horizontal read mode. In an illustrative embodiment, the touch in step 404 may not be limited to a specific touch position on the book page. Step 404 may perform the switching by a single touch without calling the menu for selection, thus increasing the convenience of use. Similarly, the user can perform the second touch once again to invoke the switching command to switch the horizontal read mode to the vertical read mode.
Step 406: in the horizontal read mode, the user can perform the first touch described above on the book page presented on the touch screen 302 to generate the first touch signal. In response to the first touch signal, the processor 304 may invoke the browsing command in the horizontal read mode, such as jump to next page. It is noted that the user also can perform a third touch that is different from the second touch in step 404 on the book page presented on the touch screen 302, and the touch screen 302 may correspondingly generate a third touch signal. In response to the third touch signal, the processor 304 may invoke a browsing command in the horizontal read mode, such as jump to the previous page. The browsing command in the horizontal read mode in step 406 is not necessarily the same as the browsing command in the vertical read mode in step 402.
It is worth to note that the difference between the touch in step 404 and the touch in step 402 (or the touch in step 406) may be the pressure applied by the user or the touch duration. Alternatively, the difference between the touch in step 404 and the touch in step 402 may be the pressure applied by the user, while the difference between the touch in step 404 and the touch in step 406 may be the touch duration. Moreover, the touch in step 406 and the touch in step 402 can be the same or different, but not limited to the described embodiments.
It is noted that the present invention can have other modifications. For example, the touch position in step 404 and the touch position in step 402 or 406 can be the same or different, and the touch position in step 402 and the touch position in the step 406 can be the same or different.
Reference throughout this specification to features, advantages, or similar language does not imply that all of the features and advantages that may be realized with the present invention should be or are in any single embodiment of the invention. Rather, language referring to the features and advantages is understood to mean that a specific feature, advantage, or characteristic described in connection with an embodiment may be included in an embodiment of the present invention. Thus, discussion of the features and advantages, and similar language, throughout this specification may, but do not necessarily, refer to the same embodiment, and need not necessarily be included in any embodiment consistent with the present invention.
Furthermore, the described features, advantages, and characteristics of the invention may be combined in any suitable manner in one or more embodiments. One skilled in the relevant art will recognize that the invention may be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments of the invention.
The foregoing illustrative embodiments are provided to illustrate and disclose the technical features of the present invention, and are not intended to be restrictive of the scope of the present invention. Hence, all equivalent variations or modifications made to the foregoing embodiments without departing from the spirit embodied in the disclosure of the present invention should fall within the scope of the present invention as set forth in the appended claims.
