Abstract

The invention provides a method for realizing left and right mouse button events and multi-objective operations on a touch screen. The method comprises the steps as follows: reference points are generated according to positions of touch points on the touch screen, and the touch screen is divided into two interaction areas according to the reference points; and the left and right mouse button events are responses to touch operations in the two interaction areas. In addition, on the basis of responses to the left mouse button events, the multi-objective operations are realized through multiple point touching or sliding touching. In the process for realizing mouse operations and the multi-objective operations on the touch screen, the operations can be finished through single-hand touching, and long waiting time and large-range moving operations are not included, so that discomfort of hands when users realize the mouse operations specifically on the touch screen is eliminated; besides, left/right hand habitual operation conversion can be realized through adjustment of ray angles for the touch operations, so that the touch experience can be enhanced, and the instinct touch feeling of people can be embodied.

Example Embodiment

[0018] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0019] The embodiment of the present invention provides a method for implementing mouse events and multi-target operations on a touch screen, such as figure 1 As shown, including: on the touch screen, the initial touch point (x', y') is first detected. According to the position of the initial touch point (x', y') in the touch screen, make a certain distance offset to determine the origin (x0, y0). For example, when the initial touch point (x', y') is at the center of the touch screen, the origin (x0, y0) is offset from the initial touch point (x', y') to (0,0) , That is, the two points coincide; when the initial touch point (x', y') is at the edge of the touch screen, in order to facilitate the touch of the left and right mouse button events, the origin (x0, y0) is relative to the initial touch point (X',y') make a certain distance (d1,d2) offset.
[0020] After the origin is determined, take the origin as the coordinate center to construct a new coordinate system with coordinate axes X'and Y'. Make two rays L1 and L2, and the angles between them and the coordinate axis X'are angle1 and angle2. The specific values ​​can be freely defined. The typical values ​​of angle1 are 135°, and angle2 is -45°, so that the two rays are A straight line is formed, and this value is convenient for right-hand operation. Such as image 3 In the display, the two ray angles are respectively 45° and -135°, which is more convenient for left-hand operation. Note that the angle of the two rays does not necessarily satisfy that the two rays are in a straight line. The above values ​​are just one of them.
[0021] in figure 1 In, the two rays divide the touch screen into two touchable areas, the lower left and the upper right. The effective touch operations in these two areas are defined as the effective touch at the initial touch point (x' ,y') The effective touch screen operation detected within a certain period of time from when the touch screen is effectively touched to when it leaves the touch screen. According to the defined judgment, the left and right mouse buttons corresponding to the initial touch point (x', y') position or the object Object1 represented by its position can be defined. For example, you can define the touch in the lower left to correspond to the left mouse button and make the left The click response of the key, the touch in the upper right area corresponds to the click response of the right mouse button. Then, detect the effective touch points in the two controllable areas. For example, the effective touch points (x1, y1) correspond to the right mouse button response. The right mouse button response can take many forms, including but not limited to displaying the command list and performing operations with other special commands. The effective touch point (x2, y2) corresponds to the response of the left mouse button. The response is an operation response to the initial touch point (x', y') position or the object Object1 represented by its position.
[0022] in figure 2 , Describes the method of judging two touchable areas, and the effective touch is determined by the touch surface. When the number of pixels in the touch surface s1\s2 is the most touchable area, it is judged as effective Touch is the corresponding response. The number of pixels of s1 in the upper right touchable area is greater than that in the lower left touchable area, then it is determined that the right button is effective in touch response. s2 The number of pixels in the lower left touchable area is greater than the upper right touchable area, then it is determined that the left button has an effective touch response.
[0023] Based on the method of judging the left and right buttons of the mouse, the method of multi-target selection operation can be realized in the process, which can be divided into point touch selection and sliding selection.
[0024] The initial touch point (x', y') corresponds to the object Object1, and the second touch point (x1', y1') corresponds to the object Object2. When a valid touch at the initial touch point (x', y') is detected and the touch at the initial touch point (x', y') has not been released, a valid left button touch operation is detected. Such as Figure 4 , The effective left button touch point (x2, y2), when a valid touch is detected and the touch is not released, that is, the left button touch point (x2, y2) touch operation has not left the touch screen. , It is detected that the initial touch point (x', y') touch is completed and then the second touch point (x1', y1') touch operation is detected. Then, after the left button touch point (x2, y2) touch is completed, that is, the left button touch point (x2, y2) touch operation leaves the touch screen, and the initial touch point (x',y' ) Selection of Object1, the second touch point (x1', y1') Object2. Similarly, before the left button touch point (x2, y2) is touched, multiple objects can be touched to realize the touch selection of multiple targets. In the process of one-touch selection, another point-touch operation on an object that has already been selected will be regarded as canceling the selection of the object.
[0025] Swipe touch to achieve multi-target operation. Figure 5 , The effective left button touch point (x2, y2), when a valid touch is detected and the touch is not released, that is, the left button touch point (x2, y2) touch operation has not left the touch screen. , The sliding of the initial touch point (x', y') is detected. Then, after the left button touch point (x2, y2) is touched, the end point of one sliding touch of the initial touch point (x', y') is the second touch point (x1', y1') position After leaving the touch screen to complete the sliding operation, the two objects Object1 and Object2 within the sliding range Rect1 will be selected. Similarly, before the touch of the left button touch point (x2, y2) is completed, multiple sliding selection operations can be completed, and sliding the touch operation on the selected object again will be regarded as canceling the selection of the object.
[0026] The above are the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principles of the present invention, several improvements and modifications can be made, and these improvements and modifications are also It should be regarded as the protection scope of the present invention.
