Method of touch interaction with single finger

Abstract

The invention relates to a method of touch interaction with a single finger. The method comprises the following steps of when a touch event touches is triggered, judging the quantity of the fingers put on a screen currently, wherein if the quantity of the fingers is equal to 1, the recognition is successful, and single finger touch interaction is conducted; according to a touch movement touchesMove event triggered by the finger on the screen, obtaining the different value of the current finger position and the finger position when touch starts, converting the different value into a scaling proportion or a rotation angle, obtaining the current gesture view, and according to the scaling proportion or the rotation angle, calculating and redrawing the gesture view after scaling or rotation. Ascaling operation and a rotation operation can be achieved simply through touch of the single finger, and the operation mode is simplified, wherein single finger scaling does not need additional control cooperation like a scaling bar and is easier to use, and single finger rotation is easy to use, the selectable interaction mode of the user is enriched, and the method can better satisfy users withdifferent requirements.

Description

technical field [0001] The invention relates to the technical field of touch screen human-computer interaction, in particular to a single-finger touch interaction method. Background technique [0002] Touch screen technology (touch screen technology) has become very popular at present. Compared with traditional keyboard and mouse input methods, touch screen input is more intuitive. With recognition software, the touch screen can also realize handwriting input and other functions. There are three main types of touch screens: resistive technology touch screens, surface acoustic wave technology touch screens, and capacitive technology touch screens. At present, the popularity of capacitive technology touch screen is higher than that of the other two. [0003] Most of the existing portable mobile devices (especially mobile phones and tablet computers) use touch screens, and all-in-one computers, notebook computers, etc. also have models with matching touch screens to choose fr...

Problems solved by technology

But there is always an unavoidable problem: not precise enough

[0013] In some cases, it is inconvenient to use the two-finger operation, and it is difficult to realize the zoom operation and rotation operation, which brings trouble to the user

For example: the size of the device is large and needs to be held with both hands, which is not convenient for two-finger operation; for example: a finger is injured, it is not convenient for two-finger operation; In the case of hand operation (one hand is covered with oil when cooking, or one hand is carrying something in the subway, etc.), it is not convenient for two-finger operation
