Description

Portable Electronic Device for Examination

The present invention is a portable electronic device dedicated to problem solving, more specifically, it stores various contents required for learning, outputs according to a user's request, and calculates a learning result (scoring result) according to the user's response to the learning content. An electronic device that can be used.

Students' learning methods can usually be divided into offline and online learning.

Off-line learning is the traditional way of learning using textbooks, worksheets, and problem books. Therefore, students or students have to carry a lot of textbooks, problem books, and workbooks at the same time. As the number of books to be viewed increases, the volume and weight become large, making it impossible to carry all the texts.

In addition, it is too much cost to purchase a problem book or reference book, and because it is slightly modified every year, can not see again after the year, the cost of the cost is further increased because you have to buy new textbooks.

On the other hand, in recent years, the computer is increasingly used for learning. That is, a learning application program for learning and solving problems offline using a computer has been developed.

In addition, due to the proliferation of internet usage, online learning using a computer or a mobile communication terminal has been proposed. That is, after accessing the learning server using a computer or a mobile communication terminal having a wireless Internet function, learning and problem solving are performed using the contents provided by the learning server.

Such an online learning method is capable of learning and solving problems in real time, and by requesting and viewing only necessary contents, there is an advantage that repetitive learning and problem solving are possible.

However, the conventional learning method using a computer or a mobile communication terminal has the following disadvantages depending on the device used.

First, when using equipment such as a personal computer (PC), portability cannot be satisfied. In other words, because it is impossible to carry a computer, it is inconvenient to study only in an environment where a computer is installed, such as a home or a school.

In the case of using equipment such as a portable notebook, there are the following disadvantages. First of all, it is too heavy to carry with a backpack, too expensive, and takes too long to boot up a computer and run a learning program and cannot be used for short periods of time on school buses or during breaks. In addition, the use time of the battery is relatively short, such as 2 to 3 hours, there is a disadvantage that can not be used for a long time.

In addition, a mobile communication terminal having a wireless Internet function such as a mobile phone or a PCS can be used, but such a terminal cannot display enough information at a time because the display is too small, and the storage space of the terminal is relatively small so that a large amount of content can be displayed. Can't save Therefore, when necessary, the content must be downloaded and used in real time, and there is a disadvantage in that a mobile communication fee increases due to a large amount of data transmission. In addition, there is a disadvantage that can not be used at all in the radio shadow area.

On the other hand, it is best to install and use a learning program in a conventional PDA (Personal Digital Assistant), but the following disadvantages still exist. Since PDAs basically store necessary programs such as an operating system (OS) and a browser, etc., in a ROM, which is a storage space, the use of the storage space is basically limited, thus limiting the use of learning programs. Will receive.

Meanwhile, Korean Patent Application No. 2000-0044311 and Utility Model Registration Application No. 2001-0010703 propose a multifunctional portable learning device. In addition to the music file playback function, such a device simply adds language learning or other educational contents. It is displaying.

The most important part of learning for candidates is "examination," that is, looking at a problem and choosing the correct answer and giving the result after the test is the most efficient way of teaching. In this regard, the portable learning device as described above is not a complete portable learning device in that it merely displays content, and is similar to a conventional portable information communication device such as a portable language learner, an electronic dictionary, an electronic notebook, a PDA, and the like. Will do.

The present invention has been made in view of the above, and is intended to provide a problem solving-only electronic device that is easy to carry and inexpensive, and has a large amount of problem content and can solve problems for a long time.

An object of the present invention is to provide a portable electronic device dedicated to problem solving.

Another object of the present invention is to download and store the problem content from a host such as a personal computer (PC) or a learning web server, and display or play only the desired content for use in problem solving. It is to provide an electronic device for solving problems that can be calculated and provided in non-real time.

Another object of the present invention is to provide a problem solving-only electronic device that allows transparent and convenient management of the student's learning and grades by viewing the scoring results for the problem content only to the person authenticated by the password.

2 is a block diagram showing the functional components of the apparatus according to the present invention.

The problem solving-only portable electronic device according to the present invention includes a central computing unit (CPU) 210, an input unit 240, a display panel 220, and a control unit, which are largely responsible for executing various programs and controlling overall components. An output means including an audio signal output device 230, a storage unit 250 that stores problem content, a power supply unit 270, and a communication interface 260 for performing data transmission and reception with an external device. In addition, a light emitting display means 281 made of LED and / or vibration display means 282 made of a vibration motor, and a timer 290 implemented in hardware or software may be further provided.

The central computing unit 210 drives a problem solving application program (Application Program) built in the device, and performs overall control of the component, thereby performing the problem solving function according to the present invention. The functionality of such problem solving applications that can be implemented using any programming language is described in detail below.

In the exemplary embodiment of the present invention, a processor of Intel's Strong ARM or higher performance is used as the central computing device, but is not limited thereto.

The input means 240 includes a keypad input means 241 as shown in FIG. 1, a touch screen input means 242 operated by a touch screen program, and a handwriting input means 243 implemented by a handwriting recognition program. However, the present invention is not limited thereto, and any other input means such as a voice input means may be additionally used.

The keypad input means 241 may include a multiple choice correct answer number key, a cursor movement key, a selection key, a problem play / pause key, a power button, and the like. Of course, other types of function keys may be added to the keypad input means for problem solving.

In order to implement the touch screen input means 242 and the writing input means 243, it is preferable that a predetermined touch screen driving program and a handwriting recognition program are installed in the device. Writing instruments may be used.

The display panel 220 as an output means may be a thin film display liquid crystal panel (TFT-LCD), an organic electroluminescent panel (Electronic Luminescence), etc., which is equipped with a touch screen function, but is not limited thereto. Display panels may also be used. It is preferable that the display panel is provided with a backlight function so that it can be used at night.

The audio signal output device 230 may be a speaker or the like. The audio signal output device 230 may be used to output an audio signal such as a warning sound, a problem of a voice type, a voice guide message, and the like, as described below.

The storage unit 250 is a memory for storing problem contents, programs, and the like, and is largely comprised of a ROM and a RAM. The ROM is used to store important programs such as system software, scoring result authentication programs, application programs, and the like which are not allowed to be changed. In the embodiment of the present invention, a 16 Mbyte size flash memory is used. RAM mainly stores data such as problem contents and problem solving contents, and it is preferable to use a flash memory of 32M bytes or more.

The problem content stored in the storage may be one or more problem content packages consisting of a number of individual problems. The problem content package may be, for example, a collection of unit-learning problems by subjects and subjects, a collection of past-course assignment questions (by subject), a list of expected problems by assignment (by subject), and a collection of English test questions such as TOEIC, TOEFL, and TEPS. In addition, it is possible to collect a collection of problems, such as listening, assessment of the English test, and may be stored together with commentary content for each problem.

The problem content stored in the storage unit may be roughly classified into text + image content that can be displayed and audio content that can output voice.

The data format of the content in the form of text + image may vary depending on the specification of the application program, and may be, for example, data by HWP, DOC, PPT, TXT, WML, XML, or the like. In addition, the data format of the audio content may be WAV, MP3, AU, RA, etc., but may be changed according to the type of the audio reproduction program.

The communication interface 260 for transmitting / receiving data with an external device may be a USB or serial port capable of transmitting and receiving data in a wired connection with a general PC. In addition, the communication interface may be a wireless internet module including a predetermined wireless communication chip, a wireless internet program, and the like for transmitting and receiving data with an external server via a wireless internet network.

The power supply unit 270 may be configured as a secondary battery that can operate for a long time and can be charged. The problem-only portable electronic device according to the present invention usually has to operate for a test time of several hours or more, so that it is desirable to be able to supply power for at least six hours.

The light emitting display means 281 is implemented as an LED, and may include a power LED, a warning LED, and other function LEDs. The warning LED can be used to notify the user when the time limit set in the problem solving has elapsed or is approaching, and the power LED can be used to indicate the power ON / OFF.

Vibration display means 282 may be implemented as a vibration motor used in a conventional mobile phone. Such vibration display means can be used to prevent noise from occurring during warning or bell warning when the time limit is imminent or terminated while solving a problem according to the present invention in a quiet classroom.

The timer 290 is preferably implemented in software. The timer 290 operates for a time limit from when the first problem of each problem content is posted, and when the expiration time approaches or the time limit expires, a warning signal is sent to the central processing unit. Function to transmit. The timeout of the timer 290 may be assigned to each problem or assigned to each problem content package. For example, a 120-minute time limit can be assigned to the entire language domain of the Mock Test, or a 1-minute time limit can be assigned to each question. The timeout information thus allocated is stored in the storage unit together with the problem content information.

In addition, the application program may display the remaining time on the panel during problem solving of each problem content package. For example, a message such as "3rd simulated TOEIC reading test: 34 minutes 30 seconds left" can be displayed on the panel so that the user can always check the remaining time.

In addition, when the above-described play / pause button is pressed in the middle of problem solving, not only the problem play but also the operation of the timer is paused, and when the play / pause button is pressed again, the problem play and the timer operation are restarted. Such a timer may be easily implemented by dividing the system clock of the device, so a detailed description thereof will be omitted.

3 to 5 are flowcharts for explaining the problem solving application program used in the present invention for each function.

3 is a flowchart illustrating a problem solving process and / or a solution explanation process. First, when the device is powered on (S311), an initial screen as shown in FIG. 8A is displayed. If the item "1. Problem Content Package" is selected in this state, a list of Problem Content Packages stored in the storage unit is output (S312). (See FIG. 7A)

When the user selects a specific problem content package using the input means (S313), the application determines whether a time limit is set in the corresponding content package (S314). If the time limit is set, the timer starts to count down (S315), and simultaneously outputs the problems included in the problem content package on the display panel (S316).

When the user inputs a selection signal to one of the examples of the currently displayed problem, selection of the correct answer to the problem is completed (S316). At this time, it is necessary to confirm which of the views the user has selected as the correct answer, a method of checking the item number of the selected view, changing the color, and displaying the same may be used.

It would also be desirable to assign a separate function key that can be deselected to change the view once selected. This is because you can change the selected view later, as in the actual test.

The application program always monitors whether the timeout expires, and when the timeout is imminent, it is desirable to be able to warn the user using a display means such as LED, bell, vibration, etc. (S317, S318). The relationship between the time limit and the warning time, warning means, etc. can be selected arbitrarily by the user.

If all the questions are correct answer selection (view selection) and the user inputs a test termination signal or if the timeout expires (S319 and S320), the answer information stored together with the content of the question and the correct answer selected by the user are selected. The problem solving process is terminated by performing scoring based on the (view selection) information and storing the scoring result in the storage unit (S321). As described above, scoring is performed only when the test end signal is input or the time limit expires, because, as described above, the selected view can be changed again within the time limit.

In order to allow multiple users to stare at one problem content, the user may log in with a unique ID and password when using the device for the first time. In this case, the scoring result of each user should be stored separately.

Of course, if there is a user's request after scoring, the step of providing the answer content for the whole problem or a part of the problem may be separately performed (S322). In particular, it will be possible to improve the learning effect by providing only the contents of the answers to the wrong questions.

Although not shown, in the event of an event in which the play / pause button is pressed during problem solving, the output of the problem content is temporarily removed from the screen, and the timer operation is suspended. In this case, when the problem content is not temporarily deleted from the screen, the meaning of the time limit may be lost by pressing the pause button and solving the problem and playing it again.

An example of a UI screen in this process is described in detail below with reference to FIG. 7.

4 is a flowchart illustrating a process of confirming a scoring result.

First, the user who wants to check the scoring result turns on the device (S411), and transmits a scoring result reading request signal to the application program by selecting the “2. View scoring result” menu on the initial screen as shown in FIG. 8A (S412). Then, the application program outputs a message for inputting a password for authentication, and receives a password input by the user (S413).

The application program determines whether to authenticate by comparing whether the received password is the same as a valid password previously stored in the storage unit (S414).

Only in case of authentication, the scoring result stored in the storage unit is read and displayed (S415, S417).

Thus, authentication is required for verification of the scoring result because the scoring result is a kind of personal information of the examinee who has solved the problem using the apparatus, and therefore it is necessary to protect it. Therefore, only the examinee himself / herself, a teacher, or a parent and the like who are entitled to view the test scores of the test takers are allowed to see the test scores of the test takers. Of course, if necessary, authentication may not be required for viewing the scoring results.

An example of the user interface screen related to viewing the scoring results will be described in detail below with reference to FIG. 8.

5 is a flowchart illustrating a process for editing problem content used in an apparatus according to the present invention.

The problem solving portable electronic device according to the present invention can be edited such that various problem contents are arbitrarily stored and deleted, thereby doubling the effect.

To this end, the application program according to the present invention provides a menu of “3. Edit Content (Delete / Download)” on the initial screen as shown in FIG. 8A. When a content editing command is input from the user (S511), similar to the scoring result reading, a message for requesting input of a password for authentication is output (S512). The application determines whether the password entered by the user and the stored password match, and permits editing of the content only when authenticated (S513).

Problem content editing can be divided into deletion of largely stored content (S521), download of new content (S531), and storage.

Deleting the content simply deletes the selected problem content from the device memory (S522), and downloads the new problem content stored in the PC by wired connection with the PC or the like, or by using an external server (Wireless Internet Service). After connecting to WAP server or WEB server, you can download the desired problem contents. That is, for downloading, the application program first determines whether the portable electronic device is connected to an external device (PC or web server) (S532), and after connecting (S533), downloads and stores a desired problem content package from the external device. (S534).

In order to fully utilize the electronic device according to the present invention, the following method may be used.

First, the first method is to purchase a recording medium (CD-ROM, etc.) in which the problem content is stored off-line, and then download / store the problem content to a portable electronic device dedicated to problem solving according to the present invention through a general PC. to be.

In the second method, the user may access a problem providing web server using a PC, select a desired problem content, download the downloaded content to a PC, and later download and save the downloaded content to the portable electronic device according to the present invention.

In addition, when the device according to the present invention is equipped with a communication module of the wireless Internet function, it is possible to download the desired problem content immediately after connecting to the problem providing web server.

6 is a flowchart illustrating a process of performing scoring by an external device such as a PC without directly scoring the portable electronic device according to the present invention.

In the foregoing description, a method of directly scoring an application installed in a portable electronic device has been described. However, if necessary, a separate external device such as a PC may perform scoring. To this end, a predetermined scoring and management application program is installed in the PC and the like and answer information for each problem content package should be stored.

When the scoring and management program installed in the PC or the like has a scoring request from the connected portable electronic device (S611), the scoring and management program receives a result of selecting a correct answer for the corresponding problem content package from the portable electronic device (S613). Then, the scoring result is calculated and stored on the basis of the answer information stored in the self (S614), and the scoring result is output on the screen (S616). Of course, similar to viewing the scoring result in the portable electronic device, the requestor may be authenticated before the scoring (S612).

7 to 8 show an example of a user interface screen when using a portable electronic device dedicated to problem solving according to the present invention, FIG. 7 shows a screen during problem solving, and FIG. 8 shows a screen during scoring. .

First, when the power of the device is turned on, an initial screen as shown in FIG. 8A is output, and when the item “1. Select problem content package” is selected from the menu, a list of problem content packages stored as shown in FIG. 7A is output.

In the drawing, "1. College mock test (1 time)", "2. TOEIC test (1 time)", "3.5 arithmetic unit 3 exercises" are illustrated and can be selected in more detail. For example, among the SAT exams, you can select subdivided into "1.1 language area", "1.2 mathematics search area", etc., and TOEIC test can be divided into "2.1 Listening" and "2.2 Reading".

When a specific problem content package is selected, a guide message screen as shown in FIG. 7B may be provided. The guide message may include the content of the selected problem content and a time limit. Pressing the "Play / Pause" button in this state initiates display and testing of the problem content.

Fig. 7C shows a screen during listening evaluation in which the problem content is an audio signal. In the SAT test of the language (foreign language) listening test, TOEIC, TOEFL listening test, etc., the content stored in the form of an audio signal is output, and the user listens to the content and selects the correct answer using the problem selection key.

Meanwhile, at the bottom of the screen, the remaining time of the time limit can be reported in real time.

7D and 7E show screens displaying a language domain problem of a SAT in text. When using the device according to the present invention, unlike the conventional printed test questionnaire, the amount of content that can be displayed on the panel is limited. Therefore, it is to be able to move freely before and after the screen using the above-mentioned "cursor direction key".

For example, when the problem is long as shown in FIG. 7D, it is preferable to press the cursor direction key to advance to the next screen as shown in FIG. 7E. Of course, pressing the key in Figure 7e will be able to move to the previous screen of Figure 7d.

Of course, the free movement of such a problem is not made in units of screens, but may be made in units of lines by moving a scroll bar such as the right side of the screen of FIG. 7D up and down.

In the present invention, basically, one problem is based on outputting on one screen, and it is preferable that the entire problem can be viewed using up and down scrolling. This is because the solving time can be known for each problem, and thus, it can be used as useful statistics by calculating the time required for each problem.

FIG. 7F illustrates an example in which problem content including text and a formula is displayed, and FIG. 7G illustrates an example of problem content including text and an image. The bottom of the screen keeps showing the remaining time.

FIG. 8 illustrates a screen during the scoring process. First, when the item “2. View the scoring result” is selected on the initial screen as shown in FIG. 8A, a screen for inputting an authentication password is displayed as shown in FIG. 8B. Usually, multiple users can see the results of the scoring, so the ID of the authenticator can also be entered. Of course, when authentication is not required to view the scoring result, the scoring result screen as shown in FIG. 8C may be directly output without the step as shown in FIG. 8B.

When the person who wants to view the scoring results enters an ID and / or a password, the application installed in the portable electronic device determines whether the entered password matches the stored password, and the scoring result screen as shown in FIG. Will print

Of course, when the problem is solved for a plurality of subjects (problem content package), a selection screen may be additionally provided to selectively view the scoring results for only a part of them.

The scoring results may include, but are not limited to, "subject or problem content title", "time limit", "number of questions / score", and "number of correct questions / score".

In the above description, all the questions are multiple choice, and thus only one example of selecting one of the views is described. However, when the handwriting recognition program is embedded, the test on the subjective problem content may be performed. That is, when the user writes the correct answer on the screen with a writing instrument such as a stylus pen, the writing recognition program recognizes the written character and checks whether the correct answer is made.

In the above description, the selection of the correct answer, the play / pause, etc. are all performed through the keypad input. However, the touch screen may replace this function. For example, numbers 1 through 5 are displayed below each problem, and the user selects one of them by hand or a stylus pen.

In addition, the device according to the present invention is used exclusively for problem solving, but may further include an electronic notebook function such as a schedule management, a timetable, a memo, an electronic dictionary function, an MP3 player function, and the like.

In addition, it may further include a function of storing and displaying contents related to learning that are not necessarily problems, for example, a textbook reference, a lecture contents of an instructor combined with an image and a voice, and the like.

As described above is illustratively described for the implementation of the present invention, it is not intended to limit or limit the scope of the present invention, other modifications or changes will be possible within the scope of the present invention.

By using the portable electronic device for problem solving according to the present invention as described above, it is possible to achieve the same learning effect as the actual test learning regardless of time and place.

In addition, since the device can be implemented at a light weight and low cost, and the content can be arbitrarily changed, the device can be used as an almost semi-permanent test tool. Therefore, it is much more economical and convenient to use than the test method using the conventional letter collection.
