Method for judging touch input and electronic device

Abstract

The invention provides a method for judging touch input and an electronic device corresponding to the method. The method for judging touch input is applied to the electronic device. The method includes that when an operation body is initially detected in a touch sensing area of the electronic device, a first contact area parameter of a first area where the operation body and the touch sensing area are contacted is obtained. After preset time intervals, a second contact area parameter of a second area where the operation body and the touch sensing area are contacted is obtained. A ratio of the first contact area parameter and the second contact area parameter is confirmed. When the ratio of the first contact area parameter and the second contact area parameter is larger than a first threshold, the first touch operation by the operation body is confirmed.

Description

technical field [0001] Embodiments of the present invention relate to a method for judging touch input and an electronic device corresponding to the method. Background technique [0002] In current electronic devices with a touch screen, when a user performs a touch input, the geometric center of the contact area between the user's finger and the touch screen is usually taken as the contact point. However, when performing touch operations such as clicking and long pressing on a fixed position on the touch screen, since the area of ​​contact between the finger and the touch screen increases from small to large, there may be a deviation between the center point of the initial touch area and the center point of the subsequent touch area. shift. Therefore, the offset error may cause the touch screen to mistakenly fail the touch operation at the fixed position as a sliding touch input. [0003] At present, a solution is proposed to avoid misidentified operations by reducing the...

However, when performing touch operations such as clicking and long pressing on a fixed position on the touch screen, since the area of ​​contact between the finger and the touch screen increases from small to large, there may be a deviation between the center point of the initial touch area and the center point of the subsequent touch area. shift

Therefore, this offset error may cause the touch screen to incorrectly fail the touch operation at a fixed position as a swipe touch input.

[0003] At present, a solution to avoid misidentification operations by reducing the sensitivity of the touch screen is proposed, but this solution reduces the sensitivity of the electronic device to respond to sliding touch input

Especially for users whose fingers have a small contact area with the device, it is easy to cause a delay in responding to the user's sliding touch input

On the other hand, for users whose fingers have a large contact area with the device, it is easy to cause misjudgment of the user's touch input response
