The electronic device may then advantageously execute the identified device functions.
Referring now to FIG. 1, a block diagram for one embodiment of an electronic device 114 is shown, in accordance with the present invention. In the FIG. 1 embodiment, electronic device 114 may include, but is not limited to, a central processing unit (CPU) 116, a display 122, a memory 118, and one or more input/output interface(s) (I/O interface(s)) 124. The foregoing components of electronic device 114 may be coupled to, and communicate through, a device bus 128.
In alternate embodiments, electronic device 114 may be implemented using components and configurations in addition to, or instead of, certain of those components and configurations discussed in conjunction with the FIG. 1 embodiment. Furthermore, in the FIG. 1 embodiment, electronic device 114 may be implemented as any type of appropriate electronic device. For example, in certain embodiments, electronic device 114 may be implemented as any type of stationary or portable electronic device, such as a personal computer, a television, a consumer-electronics device, a cellular telephone, a settop box, an audio-visual entertainment device, or a personal digital assistant (PDA).
In the FIG. 1 embodiment, CPU 116 may be implemented to include any appropriate and compatible microprocessor device that preferably executes software instructions to thereby control and manage the operation of electronic device 114. The FIG. 1 display 122 may include any effective type of display technology including a cathode-ray-tube monitor or a liquid-crystal display device with an appropriate screen for displaying various information to a device user. Furthermore, in certain embodiments, display 122 may include a touchscreen sensor that allows a display 122 to detect pressure applied by a device user on the surface of a display screen of display 122.
In the FIG. 1 embodiment, memory 118 may be implemented to include any combination of desired storage devices, including, but not limited to, read-only memory (ROM), random-access memory (RAM), and various types of non-volatile memory, such as floppy disks, memory sticks, compact disks, or hard disks. The contents and functionality of device memory 118 are further discussed below in conjunction with FIG. 3.
In the FIG. 1 embodiment, I/O interface(s) 124 may include one or more input and/or output interfaces to receive and/or transmit any required types of information by electronic device 114. I/O interface(s) 124 may include one or more means for allowing a device user to communicate with electronic device 114. For example, the foregoing means may include a keyboard device, a touch-sensitive input pad, a wireless remote-control device, a speech-recognition module with corresponding microphone, a graphical user interface with touch-screen capability, a motion sensor device, a hand-held device controller unit, or a selection button array mounted externally on electronic device 114. The implementation and control of electronic device 114 are further discussed below in conjunction with FIGS. 2-7.
Referring now to FIG. 2, a frontal drawing of one exemplary embodiment of the FIG. 1 electronic device 114 is shown, in accordance with the present invention. The FIG. 2 embodiment is presented for purposes of illustration, and in alternate embodiments, electronic device 114 may be implemented using components, features, and configurations in addition to, or instead of, certain of those components, features, and configurations discussed in conjunction with the FIG. 1 embodiment. Furthermore, in alternate embodiments, electronic device 114 may be implemented as any other type of portable or non-portable device.
In the FIG. 2 embodiment, electronic device 114 includes a display 122 for displaying appropriate information to a system user. In the FIG. 2 embodiment, electronic device 114 also includes one or more external I/O interfaces 124 to permit the system user to provide control information to electronic device 114. In many embodiments, because of the relatively small size of display 122, there is limited space for display icons and shortcuts on the screen of display 122. Furthermore, navigating through multiple levels of dropdown menus is both time-consuming and difficult, especially if a full keyboard and mouse are not available.
Therefore, the present invention allows a device user to utilize a pattern mode for inputting a pre-defined pattern to easily activate a linked function in a user-friendly manner. The pattern may be any desired pattern that is input by utilizing any effective techniques. For example, a device user may input a pattern by tracing the desired pattern on a touchscreen of display 122 or adjacent to a proximity sensor device, or on a touch-sensitive pad from external I/O interfaces 124. Alternately, electronic device 114 may include a motion sensor module that senses 3-dimentional pattern information when a device user moves electronic device 114 in a pre-defined pattern. In certain embodiments, various types of patterns may also be input by physically manipulating external controls (keys, buttons, switches, etc.) from I/O interfaces 124.
In certain embodiments, electronic device 114 may then recognize the input pattern and execute an associated device function, such as launching a desired application, entering a particular mode, or performing a specified task. In certain embodiments, a feature extractor (see FIG. 3) of electronic device 114 may create pattern features from the input pattern, and a pattern recognizer (FIG. 3) may then utilize the pattern features to recognize the specific pattern. In various embodiments, any effective techniques may be utilized to recognize an input pattern. For example, electronic device 114 may utilize pattern matching, fuzzy logic, or artificial neural network techniques to identify the input pattern. A corresponding device function may then be located and executed based upon the foregoing identified pattern.
In certain embodiments, a desired device function may be automatically launched when a device user inputs a first initial character of the desired device function by utilizing pattern input means. For example, tracing a letter “N” may launch a navigation function, or a letter “C” may launch a calculator function. The electronic device 114 may also present a device user with all function options corresponding to a first initial character that are currently supported by the electronic device 114. For example, inputting the letter “N” may provide a list including a navigation application and a notepad application.
If the device user enters one or more subsequent characters of the desired device function, electronic device 114 may responsively present the device user with an updated list of only those function options corresponding to both the first initial character and the one or more subsequent characters. For example, if the device user inputs the letter “A” after the foregoing letter “N”, then the function list may be updated to remove the notepad application. Additional details for the implementation of electronic device 114 are further discussed below in conjunction with FIGS. 3-7.
Referring now to FIG. 3, a block diagram for one embodiment of the FIG. 1 memory 118 is shown, in accordance with the present invention.

The FIG. 4 embodiment is presented for purposes of illustration, and in alternate embodiments, command database 318 may include other components and information in addition to, or instead of, certain of those components and information discussed in conjunction with the FIG. 4 embodiment.
In the FIG. 4 embodiment, command database includes, but is not limited to, individual command selections corresponding respectively to command A 440(a) through command N 440(n). Each of the commands is comprised of a pattern and a corresponding device function. For example, in the FIG. 4 embodiment, a command A 440(a) has a pattern A that is linked to a function A. In the FIG. 4 embodiment, electronic device 114 may access command database 318 to either create new commands 440 or to identify an appropriate function for a particular input pattern. In certain embodiments, some or all of command database 318 may be predefined and populated during manufacture of electronic device 114. Utilization of command database 318 is further discussed below in conjunction with FIGS. 6-7.
Referring now to FIG. 5, a block diagram for one embodiment of the FIG. 3 function database 324 is shown, in accordance with the present invention. The FIG. 5 embodiment is presented for purposes of illustration, and in alternate embodiments, function database 324 may include other components and information in addition to, or instead of, certain of those components and information discussed in conjunction with the FIG. 5 embodiment.
In the FIG. 5 embodiment, function database 324 includes, but is not limited to, a listing of applications, functions, tasks, modes, and other relevant information that are associated with electronic device 114. In the FIG. 5 embodiment, function database 324 includes a function A 540(a) through a function X 540(x).

This text command function is especially advantageous in situations where no pattern has been previously entered into command database 318 (FIG. 4).
In the FIG. 5 embodiment, command manager 316 or other appropriate entity may then recognize the input text and search through function database 324 to locate one or more identical or related matches. In certain embodiments, these function matches may be defined by predetermined text mapping rules that are selected according to any effective and appropriate criteria. Electronic device 114 may then take a specified responsive action that may include, but is not limited to, displaying information related to the identified function(s), or executing the particular function.
Referring now to FIGS. 6A-6B, a flowchart of method steps for performing a command editing procedure is shown, in accordance with one embodiment of the present invention. The flowchart of FIGS. 6A-6B is presented for purposes of illustration, and in alternate embodiments, the present invention may utilize steps and sequences other than those steps and sequences discussed in conjunction with FIGS. 6A-6B.
In the FIG. 6 embodiment, in step 612, an electronic device 114 may enter a command edit mode in response to any appropriate event including, but not limited to, a request from a device user. In step 614, the device user may input a desired pattern into the electronic device 114 using any effective techniques. For example, the pattern may be input by utilizing a touchscreen, a touch-sensitive pad, or a motion sensor of the electronic device 114. In step 616, a command manager 316 of the electronic device 114 then stores the pattern into a command database 318 in the electronic device 114.
In step 618, the device user may then select a particular device function 540 to correspond to the previously-input pattern by utilizing any effective methods. For example, the desired function 540 may be selected from a function list displayed on a display 122 of the electronic device 114. In step 620, command manager 316 may link the selected function to the appropriate pattern by utilizing any effective techniques. In certain embodiments, the command manager 316 stores the selected function 540 with the corresponding pattern in the command database 318. In step 622, the command manager 316 determines whether any more commands remain to be created. If additional commands remain, then the FIG. 6 process returns to step 614 to define any additional commands. However, if no additional commands remain to be defined, then the FIG. 6 process may terminate.
Referring now to FIGS. 7A-7B, a flowchart of method steps for performing a command execution procedure is shown, in accordance with one embodiment of the present invention. The flowchart of FIGS. 7A-7B is presented for purposes of illustration, and in alternate embodiments, the present invention may utilize steps and sequences other than those steps and sequences discussed in conjunction with FIGS. 7A-7B.
In the FIG. 7 embodiment, in step 712, operating power is supplied to an electronic device 114. In step 714, a device user may input a desired pattern into the electronic device 114 using any effective techniques. For example, the pattern may be input by utilizing a touchscreen, a touch-sensitive pad, or a motion sensor of the electronic device 114. In step 716, a pattern recognizer 322 performs a recognition procedure by utilizing any appropriate techniques to identify the previously-input pattern.
In certain embodiments, if an input pattern is unrecognized, then the command manager 318 may dynamically prompt the device user to store the unrecognized pattern and link the pattern to a corresponding function, as discussed above in conjunction with FIG. 6. Furthermore, during functions that were not initiated by entering a previously-defined pattern, command manager 316 may automatically prompt a device user to add an appropriate command to command database 318.
In step 718, in response to the input pattern, a command manager 316 may retrieve a linked command from a command database 318 to identify a particular device function 540 that corresponds to the previously-input pattern. In step 720, electronic device 114 may then advantageously execute the identified function. In step 722, the command manager 316 determines whether any more commands remain to be executed. If additional commands remain, then the FIG. 7 process returns to step 714 to select and execute any additional commands. However, if no additional commands remain to be defined, then the FIG. 7 process may terminate. For at least the foregoing reasons, the present invention therefore provides an improved system and method for effectively selecting functions in an electronic device.
The invention has been explained above with reference to certain embodiments. Other embodiments will be apparent to those skilled in the art in light of this disclosure. For example, the present invention may readily be implemented using certain configurations and techniques other than those described in the specific embodiments above. Additionally, the present invention may effectively be used in conjunction with systems other than those described above. Therefore, these and other variations upon the discussed embodiments are intended to be covered by the present invention, which is limited only by the appended claims.
