Embodiment Construction

[0046]Certain terms are used throughout the description and appended claims to refer to particular components. Those of ordinary skill in the art should understand that manufacturers may use different terms to refer to the same component. The scope of this specification and the appended claims does not use the difference in name as the way to distinguish components, but the difference in function of the components as the criterion for distinguishing. "Includes (including)" mentioned throughout the specification and appended claims is an open-ended term, so it should be interpreted as "including (including) but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other device...

Abstract

Provided is a pointer control method of a touch screen. The pointer control method of the touch screen comprises the steps of providing a first graph object on the touch screen; starting a pointer control mode on the touch screen, converting the first graph object into a second graph object and providing the second graph object on the touch screen; performing touch input on the touch screen and enabling the second graph object to correspondingly move on the touch screen according to the touch input received by the touch screen. A transparent sphere can be operated without direction touch on the touch screen, and the problem that the fingers block the target point location is solved. In addition, the transparent sphere has the optical enlargement effect on display contents under the transparent sphere, and a user can perform intuitive and accurate pointer operation under the objective limitation of small target point location caused by high resolution.

Description

technical field [0001] The invention relates to a pointer control method on a touch screen, in particular to a pointer control method on a touch screen which uses a rolling ball to simulate pointer movement. Background technique [0002] Traditional pointing devices (such as mouse, trackball, touch panel, etc.) bring considerable convenience to the use of personal computers. However, as the current man-machine interface of personal computers and smart phones is developing towards the direction of using touch screens for manipulation, if the arrow pointer on the touch screen is still operated with fingertips, the arrow pointer will often be pointed. Pointer covered and unable to accurately move the pointer to the correct position to click. On the other hand, for small-sized touch screens such as smart phones, under the trend of maintaining the small size of the screen but continuously increasing the screen resolution, the target points on the screen are also reduced accordin...
