Description

Information input device operated by detecting movement of skin, mobile information processing device, computer and mobile communication device using the same {.}

The present invention relates to an input device, a mobile communication device and a mobile computer using the input device. In particular, the present invention relates to a device such as a computer that detects the movement of a person's skin so as to recognize what a person wants to rely on. An input device, a mobile communication device and a mobile computer using the same.

When the input device according to the present invention is used, a computer or a mobile communication device can input information that a person wants to rely on by moving a finger or the like in an arbitrary space without inputting a keyboard with a finger or inputting a hand on a display screen with a pen. You can type in

Recent advances in computer technology are spectacular. The miniaturization of the main body of the computer and related devices, such as the high performance of the computer and the development of high-definition display, is remarkable.

However, the input device for inputting information into the computer is basically the same as in the early days of typing by hand, and the size of the keyboard is almost the same since the human finger is not small. In order to solve this problem, a mouse and the like have been developed. However, since the keyboard is optimal for inputting a large amount of information in a short time, the keyboard is still used a lot. Another method of writing is to write information on a computer screen or board with a sharp pen, which is not as fast as typing on a keyboard.

1 is to show a keyboard which is a conventional input device. The existing keyboard 100 has a plurality of keys 102 on a board 101 and a structure with a line 103 for transferring processed information to a computer by wire. When a specific key of the keyboard having such a configuration is pressed, information corresponding to the key is found by mapping, and this information is transmitted to a computer not shown by wire or wirelessly so that information is input to the computer.

There has been much effort to make such a keyboard small. For example, the United States Syncoutsider (www.thinkoutside.com) folding keyboard is a full-featured keyboard that can be used as an input device. This can be easily carried, but has the disadvantage of being easy to unfold and fold in a form that can be used at the time of use and breakage. Another input device is Acceleration Sensing Glove, led by Professor Pister (www-bsac.eecs.berkeley.edu) at UC Berkeley University in the United States. The glove is made of gloves and has a structure that detects finger movements by attaching multiple accelerometers at the tip of the finger, so you can input information only by finger movement without a keyboard. However, this glove has a lot of expensive accelerometers and needs to work with gloves, so it is inconvenient to remove gloves when entering information.

The present invention is to remove a number of inconveniences and problems described above, to create a sensing device having a sensor for detecting the movement of the skin on a well-moving part of the skin of the hand or face to use as an information input device. The input device according to the present invention can be used for virtual reality, mobile communication, computer, and the like.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2-1 through 2-2 show the hand as a part of the body for explaining the principles of the present invention. In FIG. 2-1, the left hand 200 is viewed from the back of the hand, and the back of the hand 202 is connected to the wrist 201, and the plurality of fingers 204 is connected to the back of the hand 202. When the finger 204 is moved downward 205, a plurality of tendons and muscle backs (not shown) inside the back of the hand 202 move and the plurality of skins 203 located on the back of the hand move in a direction perpendicular to the direction parallel to the back of the hand. Since the part of the skin to be moved is determined for each finger movement, the movement of the specific skin region 203 of the back of the hand 202 can determine which finger is moved. 2-2 is a view of the left hand 200 from the palm side. As the finger 204 moves, the parts of the palm 213 and the wrist 212 move so that the user can know which finger has moved even by grasping the movement of the skin.

This skin movement can be known in many ways. Here, it will be described with reference to the conceptual diagram of the sensor for detecting the movement of the skin according to the present invention from 3-1 to 3-2 degrees.

3-1 and 3-2 are skin movement detection sensors 300 implemented using strain gage 301. In order to configure the skin movement detecting sensor 300, one end of the strain gauge 301 is attached to the support 302 moving like the skin, and the other end of the strain gauge is connected to the other support 303 moving like the skin. The strain gauge has a characteristic that the resistance changes when the length and the cross section change, and may be used with any material such as metal, rubber, plastic, organic material, and the like.

The skin motion sensor thus constructed will be described using 3-1 degrees and 3-2 degrees. Strain gauge 301 moves with the movement of the skin, so when the skin is stretched, 303, one side of the skin, changes to the position of 304. Since the original strain gauge 301 is changed in resistance due to the change in length and cross-section, the resistance is increased or decreased by the increase of the skin, and when the increase or decrease is detected, the increase in the skin can be detected. Reference (EODoebelin, " Measurement Systems, "McGraw-Hill Book Company, 3ed., 1983), the gage factor, GF can be written as:

Where R, L, v, p and d represent the initial resistance, initial length, Poisson's ratio, resistivity and micro-change of the strain gauge, respectively. That is, if the resistance was R at the initial length L, how much the resistance increases when the length increases by dL can be obtained by the above equation. In the above formula, the two terms on the right side are almost constant, and the third on the right side represents a case where the resistivity changes rapidly with length in a material such as a semiconductor material. 3-1 degrees and 3-2 degrees, and the above equation was found to change the resistance of both ends of the strain gauge when the strain gauge moves with the skin, this resistance is applied to both ends 302, 304 of the strain gauge By detecting the voltage difference that occurs during the application, the change in resistance can be known. In other words, the movement of the skin causes a change in the resistance of the strain gage, and the change in resistance is converted into a change in voltage, so that the deformation of the skin can be known by the difference in voltage.

It has been described that the strain gauge can be used to detect the movement of the skin to detect the movement of the skin. However, the strain gauge is not necessarily used to detect the movement of the skin. Other detection methods include physical sensors that change according to skin movement such as tactile sensor, pressure sensor, shear stress sensor, acceleration sensor, and small gyro sensor. Any sensor that can be used may be used alone or in parallel. The tactile sensor may make a human skin sense, the pressure sensor detects the pressure applied to the skin when the skin is deformed, the shear force sensor is a shear force of the skin and the shear force sensor contact area when the skin is deformed In addition, the acceleration sensor detects how the acceleration of a certain position of the skin is changed, and the gyro sensor is a sensor that detects the degree of rotation when the skin is deformed by angular velocity. In order to detect the movement of the skin well, it is advantageous to regularly arrange a plurality of sensors rather than using only one of the above sensors.

It is possible to make a variety of input device for detecting the skin movement using the above various sensors. 4-1 and 4-2 show toshi as an embodiment of an input device operated by sensing the movement of the skin according to the present invention.

The input device 400 has a plurality of skin movement detection sensors (not shown) in the Toshi 401 and the inner 402 of the Toshi, the detection sensor is connected to the processing device (not shown) inside the Toshi, the skin by the processing device The movement of the motion is recognized as a special language (ie, Body Language, or Gesture), and the language is input to a nearby computer by a wireless communication means (not shown). In this case, the wired communication means may be used without transmitting information by the wireless communication means.

When the Toshi is placed on the left and right cuffs and the finger moves, the Toshi appears as a movement of the skin, and this movement is again recognized as a certain character by mapping. Since this information is transferred to a computer, characters are entered into the computer. That is, when the finger corresponding to "I love you" moves in the air while wearing the toshi, the letter "I love you" appears on a computer screen (not shown). The TOSHI 400 can be used not only as a keyboard but also as a mouse or a pointer. When the toshi 400 is inserted into the motion sensor of the skin and the inertial sensor (Inertial Sernsor, which means the acceleration sensor and the gyroscope, not shown) that can know the spatial movement of the wrist, the movement of the wrist as well as the skin You can see the movement, so if you draw a circle in the air with your finger, a circle is drawn on the computer screen.

Such toshi enables work with text input, gestures, body language, etc. in a three-dimensional space, and thus can be usefully used for various games and virtual reality.

4-2 is an input means having the same configuration as that of 4-1, and has a closed space 413 for convenience of wearing and working. That is, the input means 410 is composed of a toshi 411 having a part 413 cut off, and a skin motion sensor (not shown) for detecting the movement of the skin on the inside 412 of the toshi, and an inertial sensor (not shown) for detecting the movement of the wrist. ) Can detect skin movement and wrist movement. The operation principle is the same as that of FIG. 4-1. In this case, the space 413 is provided for convenience of wearing, but it can be worn and loosened like a wristwatch with an appropriate connection means such as a wristwatch.

5-1 to 5-2 illustrate the wearing of the input device of FIGS. 4-1 and 4-2 according to the present invention. In FIG. 5-1, the input device 502 is worn on the left hand 500. As described above, it is possible to know which finger is moved as the finger 503 is moved. The inertial sensor (not shown) inside allows the overall movement of the back of the hand. Able to know. Therefore, as you move your finger, you can also type letters, and if you draw an arbitrary shape with your finger in space, the shape can be entered into the computer, and it can act as a pointer to point to an arbitrary location. It can be usefully used in virtual reality and various games. 5-2 shows the appearance of wearing the input device according to the present invention on the wrist, the input device 512 worn on the wrist 511 detects the movement of the finger 513 of the hand 500 and the movement of the wrist. The principle of operation is the same as in 5-1 degrees.

6 shows an example of the flow of signal processing in the input devices 4-1 to 5-2 according to the present invention. Sensor 601, which is a means for detecting the movement of skin and body such as skin, wrist, back of hand, is detected 601, and this signal is processed by the processing means inside the input device to determine which character of each finger movement corresponds to. The mapping 602 is performed, and the mapped signal is transmitted to the computer 603 using a wireless or voiced means.

The input device according to the present invention may be used as an input device of a computer by itself, but when combined with a computer and a mobile communication device as shown in FIGS. 7-1 and 7-2, it becomes a more powerful means. 7-1 and 7-2 illustrate one embodiment of a mobile communication device and a mobile computer according to the present invention.

With reference to Figure 7-1 looks at the configuration of a mobile communication device according to the present invention. 7-1 illustrates the mobile communication device 720 described above worn on the wrist 701 of the hand 700. The mobile communication device 720 exchanges a signal with the input unit 702 and the outside, and can process a signal therein. The device body 703 is configured. The main body 703 of the mobile communication device has a form in which the number of key buttons is greatly reduced in existing mobile phones. In other words, the mobile communication device basic body 703 is composed of a large LCD screen 704, a microphone and a speaker 705, and a key button 706 necessary for switching to a specific mode. In addition, when a camera (not shown) is provided, it is also possible to exchange information with an image.

The operation example of the mobile communication device configured as described above will be described as an example of sending an email using mobile communication. When sending an email, it was very inconvenient to press many keyboards with one or two fingers in the conventional mobile communication device. However, in the mobile communication device according to the present invention, since the movement of the finger 710 is recognized by the input device 702, the user has a long sentence mail. Move your finger to enter and send. In this case, the mobile communication device 720 may be commanded using various gestures in the process of writing and sending a sentence. For example, the command to send a mail may be to lift your thumb. Since inputting information using only one hand may be inconvenient, the input device 722 is worn on the wrist 721 of the other hand 730 to detect the movement of a finger and wrist and transmitted to the mobile communication device 720 as shown in 7-2. You can use your fingers to enter information. The mobile communication device includes all means capable of communicating while moving, including a mobile phone. In addition, although mobile communication devices are described as examples in FIGS. 7-1 and 7-2, a mobile communication device includes all means for communicating while moving, including a mobile phone, and instead of a mobile communication device, a small computer and a PDA (personal portable terminal) It is also applicable to any means that can store and process information. In other words, similar to 7-1, you can enter and view information while walking around with your computer on your wrist.

So far, only the input device according to the present invention has been described for convenience of description, but only worn on the back of the hand or wrist, but any part of the body such as the neck or the leg can be worn, and the shape of the input device must be limited to the Toshi shape. There is no. That is, the input device may have a glove form, a necklace form, or an ankle form. It can also be worn in the form of a hair band on the forehead, or in the form of a band wrapped around the chest. That is, any means for enclosing a part of the body and inputting information by detecting the movement of the skin falls within the scope of the present invention. In addition, a mobile communication device including a mobile phone, a computer, a PDA, etc. combined with such an information input means is possible.

In FIG. 7-1, image information is recognized through a Display 704 similar to an LCD panel. The recognition unit for this person to know the information can use various things. The two-dimensional image recognition unit may include everything representing an image on a two-dimensional curved surface including a plane. That is, various methods such as projection of a screen by projection or plasma display pannel (PDP) can be used. In addition, a holography that displays image information in a three-dimensional space may be used as a recognition unit. The image information recognizing unit gives information to a person as an electromagnetic wave containing light.

In addition, in order to recognize the processed information by the ear, it is also possible for the recognition unit to recognize a person as an acoustic wave including ultrasonic waves. In this case, it is a case where information is processed as a speaker, or when a call comes in.

As another method of recognizing the processed information to a person, it is also possible to generate a vibration to convey the information to the person to be recognized. For example, when a call comes in, a vibration generator (not shown) located in the input means 720 may generate a vibration to inform the user of the fact.

As another method of recognizing the processed information to a person, the recognition unit may generate an odor and transmit the information to a person to recognize the processed information.

The recognition unit may be implemented alone or in parallel with a plurality of recognition means.
