Description
The present invention relates to an information input system using a finger movement and an input method thereof, and more particularly, to a system and method for inputting information by using a motion input unit that integrates a mouse function and a keyboard function, And more particularly, to an information input system and a method for inputting information using a finger movement that can remotely control various smart devices in a mouse mode, an operation mode, and a handwriting mode.
In recent years, the types and the penetration rates of smart devices have increased rapidly throughout the world, and smart appliances such as refrigerators and washing machines have also been added to the smart devices.
In such a smart / wearable environment, an input device such as a conventional keyboard, a mouse, and a touch pad may cause inconvenience of use.
Since the keyboard and mouse are optimized for the input of the PC environment, it is difficult to have a keyboard and a mouse in the case of a portable smart device. Therefore, the conventional keyboard and mouse are not suitable for application, so the touch interface using the position sensor is used .
In the case of such a touch interface, there is an advantage that a user can intuitively command and control an interlocked device. In recent years, a pen-shaped motion input unit capable of recognizing a touch is also developed .
However, such a touch interface is often used in a small portable smart device, but it is disadvantageous in that it is inefficient in medium and large smart devices such as a smart TV or a smart device.
In order to solve these problems, a sensor-based smart device control technology using an acceleration sensor, a geomagnetic sensor, a gyro sensor, or the like has been developed for a smart device-based smart device control technology using a camera, have.
However, in the case of the image recognition-based control technology, since the user's face, hands, and gestures must be received through the camera and a specific motion must be detected, it can be used only when there is sufficient light. It is only possible to control it.
In addition, in the case of the speech recognition-based control technique, since the user transmits commands to the smart device through the natural language, there is a disadvantage that the use of the device is limited depending on the circumstances such as noise environment and public places.
In addition, in the case of the sensor-based control technology, a product that replaces the mouse function by sensing the movement of the user's finger is described, but the accuracy of sensing is lowered and the handwriting input is impossible.
In addition, since smart devices use different input methods in recent years, incompatibility of interfaces between smart devices is increasing the burden of user's UI (User Interface) learning.
In order to solve such a problem, the information input system and the input method using the finger movement of the present invention include a motion input unit capable of integrating a mouse function and a keyboard function, and the integrated management unit includes a finger To an information input system and an input method for remotely controlling various smart devices connected to the mobile device in a mouse mode, an operation mode, and a handwriting mode .

The virtual plane is composed of the two-dimensional axes of X and Y, and the vertical and horizontal histograms of the motion coordinates obtained with respect to the X and Y axes are obtained, and the midpoints of the motion coordinates The radiation histogram is obtained while rotating in the direction of the edge of the coordinates. Since the sensor data of the motion input unit is discrete data, when obtaining the histogram, the histogram value can be obtained by supplementing the coordinates between the two points.
And one final character input information is calculated in one character group by using this.

For example, when the user inputs a character of 'e' through the finger motion information, the 'e' character may be 'a character starting to be handwritten in a loop' or ' A character consisting of one loop as a whole can be recognized in two groups of characters.
Accordingly, the decision tree algorithm is independently performed in each character group (the first decision tree algorithm), and the second decision tree algorithm is performed using the histogram characteristic by the decision tree algorithm in each character group Tree algorithm) to recognize the final character input information, that is, the character 'e'.
In addition, when the user inputs the character 's' through the finger motion information, the 's' character generally has a 'rope-free character' as shown in Table 1, Looped character '.
