Description

HAND WRITING INFORMATION INPUT SYSTEM FOR MOBILE DEVICES}

The present invention relates to a handwriting information input system for a mobile device, and more specifically, a content written by an electronic pen on a paper attached to an input tablet mounted on a portable device such as a smartphone so as to be openable and slideable by a smartphone. The present invention relates to a handwriting information input system for a mobile device employing the input method.

As the modern society moves into the era of mobile computing, the development of mobile devices that individuals carry is dazzling. In particular, mobile devices that use the front touch screen without the need for a separate input device, while users want smaller and smaller devices, and want to process more information at a glance on a large screen, as opposed to them. The proliferation of devices is increasing. Such a touch screen-based interface has the advantage of being able to input and output while maintaining a small device size because there is no need for a space for an input device, and has the advantage of providing intuitive and user-friendly interaction. On the other hand, the input interface for a touch screen that can be employed in a smartphone is four types of resistive type (resistive touch screen), capacitive touch screen, surface acoustic wave and infrared type. It is divided into two. The double resistive film type is a touch screen mainly used in personal or narrow work spaces, and has a structure in which two substrates coated with a transparent electrode layer are bonded to face each other with a small insulating rod interposed therebetween. Normally, these two surfaces are separated from each other by insulated rods, but when the pressure is applied by the input plate, the two plates stick together and the electric flow changes, causing the input to occur. A signal for position detection is applied when contacting the upper resistive film layer, and the position is determined by detecting an electrical signal when contacting the lower transparent electrode layer. The touch screen is the most widely used feature, although it is less durable than other touch screens, but it is durable and is used in various environments. It is used in personal use, home, school, office, restaurant system. Capacitive touch screen is coated with a special conductive metal on both sides of the glass, and a voltage is applied to the four corners of the screen to spread high frequency on the surface, and when the user touches it, the position of the part where the amount of current changes due to the capacitance of the human body It calculates the size and performs the input. This method, like the resistive method, is used for a wide range of semi-permanent technologies and is mainly used for POS systems, industrial operations, and common kiosks. However, although the transparency is higher than that of the resistive film method, it does not respond to a gloved hand or a stylus pen but only a finger contact. The surface ultrasonic method consists of attaching a transducer that emits sound waves to one corner of the glass, a reflector that reflects sound waves at regular intervals, and a receiver on the opposite side. Basically, after the ultrasonic wave flows through the glass panel, when the user touches the screen, it obstructs the path of sound waves and calculates its position. The entire panel is glass and the entire layer is flat, so it is durable, has the highest transparency, and has the best durability. However, it has the disadvantage of being extremely weak in a dirty or dusty environment. Because of their high durability, they are often used in public information kiosks, computer-based learning, and crowded environments. The infrared method utilizes the property of blocking infrared rays when it hits obstacles by using the straightness of infrared rays which is invisible to the human eye. In other words, the infrared light type touch screen has a structure in which a plurality of lights are arranged around the panel so that the light emitting device and the light receiving device face each other to form a matrix. When the light is blocked by the user, the output is reduced and the coordinates of the part are blocked. This is the principle of performing input through. All input devices including fingers can be input, but the disadvantage is that they are bulky and slow in response. However, such a touch screen method has the advantage of enabling the construction of a free user interface, efficient use of space, and various interactions using gestures, but it is impossible to recognize absolute positions, that is, Since the touch screen is a glass screen of the input device, since the input surface is smooth and there are no protrusions, the touch screen cannot feel the key and thus it is impossible to recognize the absolute position. In particular, in the electrostatic method, which is a touch screen method adopted in most smartphones in recent years, a touch pen cannot be used, and touch must be performed by hand, which causes a large problem of contamination of the screen, It is impossible to use the touch pen, but it causes great inconvenience when it requires detailed work. In addition, even in a smartphone employing a pressure-sensitive touch screen, the resolution of the handwriting input is low, and the input of a large amount of information is difficult because the input on a small screen is difficult. In addition, in order to write a memo or write a text message on an existing mobile device, the memo writing mode E first enters the text message mode through various function key operations, and then writes the contents using a plurality of button keys. You must go through the steps of saving or sending. Therefore, even when a message having a relatively short content needs to be pressed through a complicated step, a number of button keys have to be pressed, which causes inconvenience in input and takes a long time to write. In addition, since the type of characters or symbols that can be created 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 caller, and the caller's own individual expression is impossible.

Accordingly, the present invention is a means for inputting a large amount of information accurately and precisely in a mobile device using an electronic pen, in particular, an input tablet which is mounted in a mobile device so as to be opened and closed by a slide method, on which a plain paper is placed. We have developed an electronic pen writing input system that attaches and naturally writes on the paper with an electronic pen.

To this end, in the present invention, as a system for inputting handwriting information into a mobile device, in order to configure a non-powered electronic pen in the form of a general ballpoint pen, when an antenna magnetic force line is generated from an antenna coil disposed under the input tablet, the pen is contactless. The present invention provides an input system that operates on the principle of receiving this, generating power from the received magnetic force line, and operating the electronic pen through the generated power signal. The electronic pen of the present invention periodically generates a magnetic force line indicating its position, and the receiving unit detects the position generated by detecting the magnetic force line in real time to identify the position where the electronic pen operates, and writes using the same. The pen position.

According to the present invention, writing on a plain paper with an electronic pen in the form of a general pen enables easy, fast, and precise and accurate writing input, thereby enabling the input and utilization of emotional and free information. In particular, by writing and sending a message that embodies the user's handwriting, notes, drawing diary, and e-mail can be easily written by pen writing on general paper such as post-it.

Hereinafter, the present invention will be described in detail.

Referring to FIG. 1, the portable device 10 includes an upper body 11 and a lower body 12 that are movably coupled to each other. The upper body 11 is arranged to overlap the lower body 12, the lower body implements an open state by the horizontal slide movement. As shown in FIG. 1, a display unit 13 is installed on an upper surface of an upper body, and an input tablet 14, that is, a tablet for inputting writing information, is mounted on an upper surface of the lower body 12. On the input tablet 14, the electronic pen 20 can be directly inputted, or a sticky paper 15 such as a post-it is attached on the input tablet 14, and writing on the input tablet 14 is carried out. It is also possible. When adopting a method of writing on paper, the electronic pen 20 may use a ball pen nib in which ink comes out in the same form as a general pen, and in this case, the information to be written is written on paper and input on a tablet. The written information is transmitted to the portable device for input. When the information input to the tablet is transmitted to the mobile device, an application stored in the mobile device is used. The user first executes the relevant application of the mobile device, and then writes on a paper attached to the input tablet 14 with an electronic pen. After inputting, the handwritten information is transmitted and displayed in real time on the display unit 13 of the mobile device 10 through the application, and the handwritten information can be transmitted to the Twitter and e-mail using the application.

2 illustrates an example of an electronic pen used in the present invention. The electronic pen has a casing 21 in the form of a sleeve. The casing 21 has an accommodating chamber 22 having one side open, and a conical plug 23 is screwed into the open side of the accommodating chamber 22. In particular, the through hole 24 is formed at the end of the conical plug 23. In addition, a pen core 25 is provided in the storage chamber 22 of the casing 21. The nib 25 is composed of a body 26 filled with ink and a nib 27 coupled to the front end of the body 22. The nib 27 of the nib 25 has a through hole 24 of the plug 23. It is configured to protrude to outside through). In addition, the front end of the casing 21 is provided with a position sensor 28 for sensing the coordinate position by detecting the electric field generated from the tablet when inputting information.

With such a configuration, when the user grabs the electronic pen and writes or sketches the paper on the tablet as if using a normal writing instrument, an electric field is generated on the tablet, and the position sensor 28 of the electronic pen is connected to the tip of the nib 27. By detecting the electric field of the tablet that changes according to the movement and transmitting it to the mobile device, the written content is displayed on the display window of the mobile device. At the same time, the writing content is displayed on the paper as it is by the ink from the nib 27 in the process of contacting the nib 27 protruding from the casing 21 with the paper fixed on the tablet.

On the other hand, the position sensor 28 can also replace it with the magnetic generating means (28-1). To this end, means for sensing magnetism in the lower portion of the tablet 14, for example, as shown in Figure 3, the plurality of magnetic sensing means 31 in the form of a matrix in the lower portion of the tablet 14 Can be placed. In this case, the magnetic generating means 28-1 attached to the electronic pen 20 moves in accordance with the movement of the electronic pen, and accordingly, the magnetic generating means 28-1 approaches a plurality of magnetic sensing sensors ( 31) Different voltage values are output, and the coordinates are sensed.

Also, in this case, when the antenna coil is generated by placing the antenna coil under the tablet, the antenna coil receives the contactless point from the electronic pen, generates power from the received magnetic line, and generates power to the electronic pen through the generated power signal. It is also possible to operate.
