Embodiment Construction

[0015] The present invention will be further explained below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the content described below.

[0016] Such as figure 1 Shown is the initial state of the cursor 101 of the virtual mouse and the left touch control 102 and the right touch control 103 on the display of the touch device 104 when there is no touch operation. Generally, if there is no touch operation to the virtual mouse, The cursor 101 and the left touch control 102 and the right touch control 103 will be hidden after a period of time, and the specific time for automatically entering into hiding is adjusted by the user.

[0017] Such as figure 2 As shown, when touch operations are detected and these touch operations meet the conditions for activating the virtual mouse, a left touch control 102 is generated at the left touch point position, a right touch control 103 is generated at the right touch point p...

Abstract

The invention provides a user's interface allowing a user to use fingers to control a mouse cursor displayed on a touch screen. Only when two fingers contact the touch screen simultaneously, and certain distance limit between two contacts is met, a virtual mouse can be activated. When the virtual mouse is activated, the mouse cursor appears in a position which is close to the two contacts and which is not sheltered by the fingers. Two touch controls are displayed with the two contacts as the center, and the user drawing an optional control can make the cursor move synchronously. By means of the control mode, the user is allowed to see the cursor when the cursor moves, and small objects which are difficult to be targeted before can be targeted easily and accurately. In addition, when the finger clicks or presses the left or right sides of the touch controls, that is to say, similar operations are performed on the left or the right key of the mouse. The control mode is closer to operational habits of a traditional mouser as compared with other method using a touch screen to control the mouse to move.

Description

technical field [0001] Aspects of the invention relate generally to controlling a displayed cursor on a computer display, and more particularly, to controlling the cursor with a finger through cursor control interaction associated with the cursor. Background technique [0002] Touch-sensitive surfaces are rapidly becoming more common in computing devices. They are very convenient because they allow the user to make natural gestures on which the user is familiar, such as inputting handwriting by using a special stylus, and many of these devices also allow input provided by the user's fingertips. The term touch-sensitive surface or device will be used herein to refer to a surface or device configured to detect the touch of any type of "stylus", such as a specially designed stylus device or a user's finger. One disadvantage of using a finger or a stylus with a larger area tip is that it is difficult to aim precisely where the finger will touch and to use the finger to aim at s...
