Abstract
The input device of the present invention is a gesture recognition input device using an external multi-touch touch pad, which is an input device for controlling a mouse by placing a palm on a touch pad instead of just touching a finger.
Previously, only fingers were used to accumulate hand fatigue when used for a long time, which made it difficult to use for a long time.However, this method uses up to the palm, so there is no fatigue even after a long time. It is an interface technology that can replace.
Accordingly, the present invention is an input device designed to increase the accuracy of input by reducing the fatigue caused by long-term use only by the diversification of input methods and existing fingers and to reduce the hand fatigue even when used for a long time.
Description
Input devices applying the conventional capacitive touch associated with PCs, laptops, or tablet PCs include touch pads and touch screens. Touchpad is a generalized input device that is basically installed in laptops, and the touch screen is gradually being applied to the method of directly touching the screen such as smartphones and touch screen monitors.
The input device according to the present invention is a gesture recognition input device using an external multi-touch touch pad, the configuration of which is as shown in FIG.
The input device according to the present invention is an external type such as a PC, which is characterized in that the mouse pointer is controlled in a state in which the entire palm is naturally placed instead of simply being touched by a finger.
Existing touchpad is limited to the operation by placing one finger or a plurality of fingers on the touch pad to prevent the desired operation when other parts such as the palm touches.
As can be seen from the operation of the mouse, for a long time touch operation, as long as you use the palm to the floor to touch only a predetermined finger as in the present, it becomes impossible to use for a long time and the fatigue increases.
Therefore, the present invention has been devised to improve the accuracy of input by reducing the fatigue caused by long-term use when using only the input method and the existing finger only to increase the accuracy of input and to reduce the fatigue of the hand even when used for a long time. An object of the present invention is to provide a method for improving an interface according to characteristics of a screen device.
Therefore, the present invention is to identify and distinguish the difference between the signal when the palm and finger touch, that is, the area of the touched signal (area of the position where the signal strength is greater than the surrounding signal) for palm recognition.
In addition, to solve this problem by using the angle between the palm touch signal and the finger touch signal to distinguish each finger.
With all the palms on it, you can control all your PCs using all the features and additional convenience features of your existing mouse, making it even more intuitive and seamless.
Existing mouse or notebook touch pad is limited to simply moving the pointer and controlling it. However, the palm pad of the present invention can be applied to a virtual keyboard according to the user's convenience.
Existing mouse is a three-dimensional form, the user is too bulky and inconvenient to carry, such as a notebook, but the touch pad is thin, it is easy to carry.
The palm pad of the present invention can be said to have high utilization because the pad material is made of a flexible material, which makes it easier to carry and can be made into a protective pad function that functions as a protective case such as a Tablet PC.
BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate preferred embodiments of the invention and, together with the description, serve to further the understanding of the technical idea of the invention, And shall not be construed as interpretation.
1 is a diagram illustrating the shape of touch signals when a palm is touched on a palm pad
2 is a fan-shaped figure between palm and finger touch signals
3 is a farm mode, multi-touch mode switching procedure diagram
4 is a detailed configuration of the palm pad
When the user's hand is naturally placed on the touch pad, the touch signal sensed by the touch pad is generated by the palm and the tip of the finger, and the touch pad according to the present invention continuously monitors the signals generated by the hand and checks the movement. do.
As shown in FIG. 1, the touch signals P1 and P2 sensed by the palm of the hand are represented as a very large area compared to the finger signals F1 to F5, and thus are recognized as palms in the touch controller or the touch driver. In particular, the palm of the lower part of the thumb and the little finger to form a V-shape, the shape and size of the palm is easy to new style.
In addition, as shown in FIG. 2, in the case of a finger signal, the touch signal formed by each finger due to the shape of the hand is formed at a predetermined angle in a fan shape with respect to the palm and is generally a touch signal F1 by the thumb. , Detection of the signal F2 by the index finger, F3 by the middle finger, F4 by the ring finger, and F5 by the little finger are possible.
In this way, when the hand is placed on the touch pad and recognizes each finger separately, it is possible to add a variety of additional functions in addition to the function of the existing mouse through a single action or a complex action of each finger through the touch pad. Can be replaced.
Palmpad can provide various functions through Palm mode and Multipoint touch mode in addition to navigation, select, drag, and scroll functions, which are common mouse functions. Palm mode is a mode in which a user comfortably places a hand on a palm pad and controls it using a palm and a finger. Multipoint touch mode is a mode in which a user controls a specific single or multiple finger touches like a conventional touch pad. to be.
The basic operational process is as shown in FIG.
If there is no touch, the touch pad stays in the standby state and once the touch of any type is recognized, the touch pad analyzes the type of touch. As shown in FIG. 2, if the palm type touch is generated or simply a touch by a finger or the like, the type is checked, and if the palm touch occurs, the user enters the Palm mode, and in the case of a simple touch, enters the Multipoint touch mode. do. When entering the Palm Mode, the touchpad monitors the position of the palm and the position of each finger in real time, and recognizes the actions taken by recognizing the independent change of each touch signal. In this process, if the palm is continuously touched and the palm is stuck, if the palm is stuck, it will continue to play the Palm Mode and if the palm is away, if the other finger is still touched in addition to the palm, it will switch to the multipoint touch mode. Will recognize the touch.
In the process of multipoint touch mode, the palm touch is continuously monitored and the palm mode is entered when the palm touch is recognized.
Palmpad hardware configuration is a multi-touch sensor unit for detecting the touch signal by the user's fingers and palms as shown in Figure 4, a touch controller for processing the signal of the sensor unit, and the touch signal for communicating with the PC and the like via USB It consists of a serial communication unit, a communication terminal and a power supply terminal forming a USB connector, and a touch driver for linking touch signals of a touch pad with a control unit such as a PC.
-Multi-touch sensor: It is composed of hard form to replace the function of a general mouse or soft material on the flexible sensor like a real mouse pad so that it can be rolled or folded.
-Touch controller: Recognizes the touch signal from the sensor, converts the intensity of the touch based on each channel coordinate and transfers it to the touch driver through the communication unit.
-Touch driver: It analyzes the touch signal from the touch pad, extracts palm information, finger information, gesture information, etc. to control the movement of the mouse pointer and delivers the relevant action to the PC.
P1 ~ P2: Palm Touch Point
F1 to F5: Each finger touch point
