Description

How to Search for Key Sequences {KEY SEQUENCE SEARCH METHOD}

The present invention relates to a key sequence retrieval method of a Man-Machine Interface (MMI), and in particular, only a part of a key sequence input for MMI control used in a mobile terminal is input and then a corresponding function is retrieved. The present invention relates to a key sequence retrieval method that makes it possible to use an ambiguous function by referring to a list and description of a key sequence included.

The general meaning of MMI is the information exchange function or information exchange device between a computer application system or a computer control system and an operator or a process engineer who operates it, and can be thought of as a computer peripheral device in a broad sense. In the MMI, the output is input to a human (operator) and the input is output from a human, so it is important to fit the human characteristic and the environmental characteristics in which the human is working. Printers, typewriters, CRTs, operator consoles, various projectors, keyboards and switches, data readers, voice devices, and driving monitors are the main components of the human-machine interface, and their shapes, sizes, arrangements, types and colors In terms of lighting, operability, etc., it is necessary to be in harmony with the installation environment and the suitability of human intelligence, psychology, and emotionality.

Various applications or applications for MMI vary considerably, and user-machine interfaces used in wireless terminals or devices such as mobile phones, pagers, and personal digital assistants (PDAs) are also a type of MMI.

Now, let's look at the narrower meaning of MMI. Although the general user interface also shares the meaning of MMI, the MMI used for mobile phones analyzes user key input using a keypad and a display, which are user interfaces, and interprets them by syntax and executes the corresponding actions. The key sequence, which is a procedure of key input, is a scripting language that can be linked with a function of a system operating software, and can be designed differently according to a corresponding device, and uses an MMI module that can interpret it.

The MMI module separates an input key sequence into minimum units having meanings, and analyzes the key sequence (script grammar) by using a parser. The grammar is then interpreted and the function allocator calls the corresponding function in the system software to perform the control functions.

For example, when a key is input in a key sequence having a predetermined rule in order to register / cancel an additional service, the corresponding operation is executed to register / cancel the additional service.

IMEI (International Mobile Equipment Identity) is a unique number of a mobile terminal, which is usually 15 digits, which can be confirmed by the user by a predetermined key sequence.

In addition, unstructured supplement service data (USSD) for controlling non-standardized supplementary services, subscriber identity module (SIM) for managing personal authentication contents, and the like may also be controlled by inputting keys in a predetermined key sequence.

The key sequence for inputting such additional services is regarded as an MMI used in a mobile phone.

The key sequence for MMI control that can be easily used by the user is the registration and release of supplementary services, such as caller ID display, remote control service, call prohibition, call waiting, call rejection, call forwarding, and tracking connection. To register, you need to register using a key sequence provided by the manufacturer or carrier.

However, this key sequence is not only complicated, but also difficult to remember because it is mostly a combination of simple numbers and * and # keys. Therefore, you need to find the manual or reference material and input Chinese characters. In addition, such key sequence inputs are not easy to operate, so most users do not use them frequently.

For example, assume that the format of the key sequence for call forwarding is "** 21 * target phone number * 11 # <call>". "<Call>" means a call key of the cellular phone.

1A to 1B are conventional simple key input screens, which are screens inputted in a key sequence from a standby screen in order to use a call forwarding function. Here, for example, suppose that you want to register a call forwarding to the phone number 02-123-4567, '** 21 * 021234567 * 11 #' must be entered in order. It's hard to remember this, so you'll need to have a manual or reference material nearby to use it.

First, as shown in FIG. 1A, a key is input from a standby screen while viewing a user reference material. Then, characters are displayed on the screen sequentially, such as pressing a keypad in general. Continue to press the keypad until it is displayed as shown in FIG. After that, press the <call> key to register, listen to the confirmation sound or confirm the message, and then press the <end> key to complete the registration.

If the user wants to release it or register again, the first part may be vaguely remembered, but it is not easy to remember it completely.

As described above, it is difficult to remember a key sequence having a predetermined rule. Therefore, it is difficult to use the key sequence when there is no reference material. There was a problem to give up.

In view of the above problems, the present invention lists a list of key sequences that include only a portion of a key sequence and then searches through the search function. An object of the present invention is to provide a key sequence search method for finding and using a desired key sequence.

1 is a conventional key sequence input screen.

2 is a key sequence input screen of the present invention.

3 is a flowchart showing the procedure of an embodiment of the present invention.

In order to achieve the above object, the present invention provides a method for retrieving a key sequence of a mobile phone having a human-machine interface control function, wherein a user inputs a part of a key sequence starting with "*" or "#" and retrieves a function. Selecting a; Outputting a list of key sequences having a part of user input through the search and waiting for a user's selection; And if the user selects a desired key sequence from the list, outputting a description including the format of the corresponding key sequence.

The selecting of the search function may further include a submenu outputting step of selecting whether to search by key or search by name.

In addition to the above-described method, after a part or all of the format of the key sequence is automatically input through a predetermined selection key input on the description screen of the key sequence selected by the user, waiting for a subsequent input or correction by the user. It further comprises.

Reference to Figures 2 to 3 to describe the present invention as described above in detail.

2a to 2f are execution screens showing the present invention by way of example, and show an embodiment to which the present invention is specifically applied. Therefore, the present invention can be applied in a manner different from the present embodiment, which will be referred to while describing the present embodiment.

2A illustrates a state in which an MMI key input is started on a standby screen, which is the same as a general key input state.

2B shows a menu for automatically searching for a key when the key input is recognized to be MMI. Naturally, the automatic output of the key search menu is only a specific embodiment of the present invention, and the search can be performed by using a predetermined shortcut key. Here, we printed out the key search menu to verify that the user is currently entering part of the key sequence, which allows the user to search for a key sequence containing "** 2". You can continue.

FIG. 2C is a diagram for determining a submenu to list a result list by pressing a key to which a key search menu is assigned in the screen, and may also list keys of a key sequence including a currently input “** 2”. You can also list the names of key sequences that contain "** 2". This submenu is also to be understood as an example of application, and any result output method may be used without such a submenu.

FIG. 2D illustrates a case where the 'search by key' menu is selected in FIG. 2C and lists keys of a key sequence including "** 2". In this example, only two are shown.

The user can select the desired key sequence with the appropriate key operation from the corresponding list.

FIG. 2E illustrates a case where the 'search by name' menu is selected in FIG. 2C and lists names of key sequences including "** 2". Again, only two are shown, but many can be displayed.

FIG. 2F is a case in which "** 21" or "unconditional incoming call registration" first shown in FIG. 2D or 2E is selected, and includes a format as shown in the figure.

After completing the search, the user can input the searched content and execute the corresponding function. As shown in FIG. 2F, the 'selection' menu is automatically displayed on the description screen, so that the user can select the 'selection'. By pressing a corresponding key or pressing a predetermined shortcut key, some or all of the corresponding format may be automatically recorded on the input screen, and the user may wait for subsequent input or editing.

For example, by pressing the Select key in the description of the selected 'Unconditional Call Forwarding', "** 21 * * 11 #" can be automatically displayed in the input window, where * indicates the current cursor position. Can indicate that the input of can be inserted into this part.

Or "** 21 * phone number * 11 #" can be printed to allow the user to edit the 'phone number' part. These various changes can be applied without departing from the invention.

Thus, the user only needs to edit the portion that the user must enter or only enter the subsequent portion of the displayed key sequence. Such a function may also be an application example of the present invention as a function added to a search function.

FIG. 3 shows the contents described in FIG. 2 in a flow chart form, which shows the overall flow of the present invention.

As shown, when a user enters some of the MMI keys, a search menu is automatically displayed. If the user does not use the search function, the user will continue to accept the input, and the MMI key input is terminated by executing the function after the user completes the input.

However, if you use the search menu, it lists a list of key sequences that contain your current input. In this case, a form of a list that is listed through a lower menu that receives an additional input of a user may be set. As described above, an initial portion of the keys of the key sequence may be listed, or may be listed by name for easy identification by the user.

Subsequently, when the user selects one of the lists using the numeric keys or the arrow keys, a corresponding description is displayed, preferably including the type of the corresponding key sequence. This allows the user to use the function description and format of the key sequence without reference.

By simply searching for the desired key sequence, the user can conveniently use the key sequence without reference. Also, by adding additional automatic input function, the user's convenience can be improved.

As described above, the present invention allows the user to input only a part of the MMI key sequence and then list a list of key sequences including the search function. When one of the lists is selected, the user can check the contents and format thereof. Even if you don't know the function, you can easily check and use the key sequence you want with the built-in search function, and it can maximize the user's convenience by adding a function that minimizes user input.
