The present invention relates to a moving trajectory measurement method of a reader and a reader using the same.

A portable device is an information processing device that performs various functions while the user moves freely, such as a PDA, a portable multimedia player (PMP), a mobile phone, and a smartphone.

In particular, a mobile communication portable device such as a mobile phone freely moves within a service area of a mobile communication system and communicates instantly with a desired counterpart anytime and anywhere through a mobile communication base station. Such mobile communication devices have been generally used because they are convenient to carry and free to communicate. In addition, in recent years, in addition to the basic service of making a phone call, various additional services such as memo writing, text message transmission, and photography are continuously being developed.

In particular, the memo writing service in mobile devices such as PDAs and electronic notebooks can be written anytime, anywhere, without having to carry writing instruments and papers such as memo, memo, or memo that are usually suddenly remembered. The text message transmission service is widely used because it is possible to simply and quickly deliver the contents created by the caller by creating a letter, a symbol, a number, an emoticon, etc., and transmitting the same to a designated counterpart through a mobile communication base station.

However, in order to write a memo or write a text message on an existing mobile device, first enter a memo writing mode or a text message mode by operating various function keys, and then write contents using a plurality of button keys, and then store the contents. Or transfer. Therefore, even when a message having a relatively short content needs to be pressed, a plurality of button keys have to be pressed through complicated steps, and thus, input is inconvenient and the writing time is long.

In addition, since the type of characters or symbols that can be written is limited to the characters or symbols already stored in the mobile device, there is a problem in that it is not possible to freely express various information intended by the sender, and the unique expression of the sender is impossible.

Accordingly, an object of the present invention is to provide a method of measuring a movement trajectory of a reader and a reader using the same, which facilitates an input and shortens the writing time of a character or a symbol by creating and storing / transmitting contents as if writing with a pen.

On the other hand, the reader according to the invention is characterized in that the program for executing each step is installed.

According to the present invention, by writing and storing / transmitting the contents as if writing with a pen, it is possible to simplify the input and shorten the writing time of characters or symbols.

In addition, according to the present invention, information input and transmission freely expressing various characters or symbols can be made freely regardless of a font or a format previously stored in a mobile device.

In addition, according to the present invention, it is possible to perform a variety of input functions even without a separate keypad.

Hereinafter, with reference to the drawings will be described the present invention in more detail. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

As shown in FIG. 1, the reader 100, which is a movement trajectory measurement object in the present invention, may be preferably manufactured in a pen-like form, and the user may write using the reader 100 having a pen-like form. In the reader 100, the handwriting trajectory of the user may be measured.

In order for the reader 100 to measure the movement trajectory of the reader 100 that the user moves, when the user writes using the reader 100, the user displays a code indicating the corresponding location information for each location. It should be written on the printed matter 150.

Specifically, when the writing starts, the reader 100 reads the position information of the starting point 1 on which the writing starts on the printed matter 150. On the other hand, the reader 100 measures in real time the pressure applied to the end of the reader 100 when writing the end of the reader 100 to the printed matter 150.

At the start of writing, the pressure value applied to the end of the reader 100 appears, and at the time when the pressure value appears, the reader 100 reads the position information on the printed matter 150. The position information at the time is stored as the position information of the starting point 1.

Afterwards, when the user continues writing on the end of the reader 100 on the printed matter 150, the pressure value applied to the end of the reader 100 continues to appear and the reader 100 is printed on the printed matter 150. Will move on.

That is, while the reader 100 moves while the pressure value continues to appear, the reader 100 measures the relative coordinate change according to the movement of the reader 100, and the position information of the starting point 1 and the reader 100. The reader 100 extracts movement trajectory information of the reader 100 based on the relative coordinate change amount measured according to the movement of.

On the other hand, if the pressure value applied to the end of the reader 100 does not appear, this means that writing has been stopped, the reader 100 at the time point that the pressure value does not appear, the reader 100 displays the position information on the printed matter 150. It reads, and stores the position information at this time as the position information of the end point (2).

That is, the reader 100 accurately measures the movement trajectory of the reader 100 through the position information of the start point 1, the relative coordinate change amount measured according to the movement of the reader 100, and the position information of the end point 2. It becomes possible.

Figure 2 is a flow chart illustrating the principle of the movement trajectory measurement method of the reader according to the present invention. Referring to Figures 1 and 2, when explaining the principle of the movement trajectory measurement method of the reader 100 according to the present invention, the reader 100 has a predetermined threshold value of the pressure value applied at the end of the reader 100; It is determined whether or not (eg, '0') is exceeded (S210).

When it is determined that the predetermined threshold value is exceeded, the reader 100 reads the position information of the point where the reader 100 is located on the printed matter 150 as the position information of the starting point 1 at that time (S220). .

After the measured pressure value exceeds the threshold value, when the reader 100 moves on the printed matter 150, the reader 100 measures the relative coordinate change according to the movement (S230). In measuring the relative coordinate variation, it is preferable to use a position movement measurement method in an optical mouse that is generally used, or to use a motion vector of an image acquired by the reader 100 on the printed matter 150. will be.

The reader 100 may extract the movement trajectory information of the reader 100 based on the measured relative coordinate change amount from the position information of the read writing start point 1 (S240).

The reader 100 transmits the extracted movement trajectory information to an external monitor or an external printer and outputs the same, thereby displaying the contents written by the user using the reader 100.

On the other hand, in the practice of the present invention, in step S230 described above, the reader 100 for measuring the relative coordinate change according to the movement of the reader 100 may continuously measure the pressure value applied to the reader 100 together. will be. In this case, the reader 100 may extract the movement trajectory information of the reader 100 based on the measured relative coordinate change amount and the continuously measured pressure value from the position information of the read writing start point 1. (S240).

As such, when extracting the movement trajectory information of the reader 100 in consideration of the pressure value, the reader 100 may acquire the movement trajectory information reflecting the thickness of the written character or symbol according to the degree of pressure applied. . Accordingly, when the content written by the user using the reader 100 is displayed by an external monitor or an external printer, the thickness of the letter or symbol written by the user may be reflected and displayed.

On the other hand, in the practice of the present invention, the user will be able to extract more accurate movement trajectory information of the reader 100 by checking the position information of the end point (2) which is the end point of the writing.

That is, the reader 100 determines whether the pressure value applied to the end of the reader 100 is equal to or less than a predetermined threshold value (for example, '0') (S250), and the pressure value is a predetermined threshold value. In the case where it is determined to be the following, the reader 100 reads the position information of the point where the reader 100 is located on the printed matter 150 as the position information of the end point 2 at the point in time (S260).

In addition, in the practice of the present invention, the reader 100 not only reads the position information of the end point 2, but also periodically in accordance with a predetermined time period while the reader 100 moves as shown in FIG. The position information on the printed matter 150 may be read, and the position information of the read reader 100 may be used to correct the movement trajectory information of the reader 100 extracted in step S240.

On the other hand, the reader 100 reads the position information of the end point 2 which is the point where the writing is finished, and then corrects the movement trajectory information of the reader 100 extracted in step S240 based on this, thereby the reader 100 The movement trajectory information of can be measured more accurately.

In addition, when the reader 100 reads the position information of the end point 2, the reader 100 recognizes this as the end of writing and moves the movement trajectory information measured up to the point in time when the position information of the end point 2 is read. It is separated from (S270).

The movement trajectory information of the reader 100 separated as described above is transmitted to the reader 100 and simultaneously transmitted to a server, an external monitor, or an external printer that manages the movement trajectory of the reader 100 (S280).

On the other hand, the reader 100 according to the present invention will be installed a program to execute each step of the above-described step S210 to step S270.
