Abstract

The present invention relates to an algorithm and method for implementing the same, which makes it easier to use a touch screen-based device such as a tablet by analyzing the information of the touch area transmitted from the touch panel and separately detecting the touch information of the fan and the touch information of the hand. will be.

Description

Algorithm for separating pen and hand multi-touch {pen finger multitouch algorithm}

The present invention relates to an algorithm and a hardware configuration method designed to correct the weakness of the existing touch screen and recognize the touch of the human body and the touch of the fan. The existing touch screen separately recognizes the touch of the fan and the touch of the finger. Even if you do not recognize or separate, even if the user's most comfortable posture, the fan and palm multiple touch occurs, it does not recognize the separation at all, so in order to draw a picture using the fan, the palm has to be separated from the touch panel. It is a technology that corrects the inconvenience of the existing touch screen through algorithm and hardware configuration that can draw a picture correctly even when attaching a palm.

Touch Screen Touch Area Recognition Algorithm

If you want to use the zoom-in zoom-out function by using the multi-touch after drawing with the pan on the touch screen, you can perform the above operations with your finger, but there are problems in accuracy and convenience compared to drawing with the pan. . In order to solve this problem, it is necessary to develop a device or an algorithm according to which the fan is in contact with the body.

Touch area recognition simulation application development tool, electrostatic touch screen

Develops pressure type touch screen and device driver

The touch screen allows you to recognize the contact between the fan and the body,

Makes it easy to use touch screen devices. For example, if the palm is in contact with the touch screen and the user can draw with a fan, there will be no user-friendly input.

1 is an operation of the algorithm of the present invention.
2 is an exemplary screen related to a method of dividing a touch area according to the present invention.
3 is a flowchart illustrating an algorithm operation method related to a method of dividing a gesture of a device that receives an input at the time of making a touch of the present invention.

1. Algorithm for separating pan touch and body touch

Since the touch screen operates by recognizing the touch area of the screen, the size and location information of the touch area is basically transmitted to the operating device. The purpose of this algorithm is to receive this information and recognize whether it is the body or the fan who is touching the screen. Fans and hands can make a distinct difference in the area of contact between the screens and thus determine the final operating gesture of the operating device.

Referring to FIG. 2, the contact area of the screen according to the multi-touch of the finger and the palm and the fan are in contact with each other. Unlike operating methods of other devices, when the contact points 1 and 2 of FIG. 2 occur, the contact information of the palm occupying a large area is ignored and the fan or finger occupies a small area. Since the operation area should be notified, the contact area is grayed out, and the average value for each type of touch is evicted and the final decision on the touched state is compared to the current touched state so that the algorithm can make a final decision. The method is determined based on the form of FIG. 2.

2. A mechanical device that recognizes the separation between the touch and body touch

When using a capacitive touch screen, using a regular fan does not know whether the fan has been touched. Therefore, the device should be mounted so that current flows in the fan, so that the fan is touched on the screen. However, if the device is configured only this way, the contact between the body and the fan is not distinguished, so the fan can be distinguished by the strong current other than the body or the low current flows, or the contact is made on the touch screen. Signaling the pressure applied to the fan through a variety of wireless communication operating in the touch screen operating devices, such as Bluetooth or infrared communication can be easily distinguished that the fan is touched.

3. How to handle screen event when screen contact between fan and body occurs simultaneously

According to Fig. 3, the event is divided into the DRAW mode and the Press mode.
