Abstract

A method for determining a touch point during a special touch object contacting with a touch screen, and a touch screen operating tool, in particular a touch pen. The method includes: installing a sensor on the special touch object, comparing the data of the special touch object obtained by the sensor with the corresponding data of the contact point on the screen, determining the corresponding touch point of the special touch object.

Claims

1. A method for determining a particular touch object corresponding to a touch point, characterized in that the data of the particular touch object obtained by a sensor is compared with the relevant data of the touch point on a screen to determine the touch point corresponding to the particular object, and the data the sensor can obtain comprises, but not limited to, one or more than one of the following data:

sending signal at the moment the particular object touches a touch screen system;

moment the particular object touches the touch screen system;

movement speed of the particular object and a contact point of the touch screen;

movement direction of the particular object and the contact point of the touch screen in relation to a built-in coordinate system;

pressure of the particular object and the touch screen;

acceleration of the particular object and the contact point of the touch screen;

and rotation of the touch object.

2. A touch object, characterized in that the sensor is installed, the system can operate the touch screen through the touch object according to the information obtained by the sensor, and especially, a response different from other touch objects can be given when the touch screen is touched.

3. The touch object according to claim 2, characterized in that the data the sensor can obtain comprises, but not limited to, one or more than one of the following data:

sending signal at the moment the particular object touches or getting close to a touch screen system;

moment the particular object touches the touch screen system;

movement speed of the particular object and a contact point of the touch screen;

movement direction of the particular object and the contact point of the touch screen in relation to a built-in coordinate system;

pressure of the particular object and the touch screen;

acceleration of the particular object and the contact point of the touch screen;

and rotation of the touch object.

4. The touch object according to claim 2, characterized in that when the touch object is operating a touch screen simultaneously with other touch objects, the touch screen can generate the effect different from other touch objects.

5. The touch object according to claim 3, characterized in that when the touch object is operating a touch screen simultaneously with other touch objects, the touch screen can generate the effect different from other touch objects.

6. The touch object according to claim 15, characterized in that when the touch object is operating a touch screen simultaneously with other touch objects, the touch screen can generate the effect different from other touch objects.

7. The touch object according to claim 2, characterized in that the touch point corresponding to the particular object is determined by comparing the data of the particular touch object obtained by the sensor with the relevant data of the touch points on the screen.

8. The touch object according to claim 3, characterized in that the touch point corresponding to the particular object is determined by comparing the data of the particular touch object obtained by the sensor with the relevant data of the touch points on the screen.

9. The touch object according to claim 15, characterized in that the touch point corresponding to the particular object is determined by comparing the data of the particular touch object obtained by the sensor with the relevant data of the touch points on the screen.

10. The touch object according to claim 2, characterized in that the sensor can detect whether the touch object is rotated, and the system performs relevant operations when the touch object is rotated and the touch point corresponding to the touch object does not move on the plane where the touch screen is positioned.

11. The touch object according to claim 2, characterized in that the sensor is equipped with an elastic ball capable of rolling, and determines the rolling situation of the elastic ball through a relevant structure, such as gear or grating to determine the movement situation of the particular object.

12. The touch object according to claim 2, characterized in that a key or a switch is arranged on the touch object, so a user can start up or shut down the sensor or switch to the touch object-corresponding function by means of the key or the switch.

13. The touch object according to claim 4, characterized in that the touch object is pen-shaped.

15. The touch object according to claim 2, characterized in that the sensor sends the signal owing to being pressurized.

16. The touch object according to claims 15, characterized in that the sensor adopted detects the occurrence of the touch through the following structure:

when the touch occurs, a circuit in an elastic structure of the sensor is switched on owing to pressure, the signal is sent, and the elasticity of the elastic structure can be obtained by means of spring or electromagnetic principal or elastic material;

when the touch occurs, the relevant circuits in the elastic structure of the sensor generate electromotive force owing to movement based on the principal of electromagnetic induction and are controlled to send the signal, and the elasticity of the elastic structure can be obtained by means of spring or electromagnetic principal or elastic material;

and the occurrence of the touch applies pressure to piezoelectric material which generates electric potential, and the electric potential controls the relevant circuits to send the signal.

17. The touch object according to claim 15, characterized in that the touch object is pen-shaped.

18. The touch object according to claim 5, characterized in that the touch object is pen-shaped.

19. The touch object according to claim 7, characterized in that the touch object is pen-shaped.

20. The touch object according to claim 8, characterized in that the touch object is pen-shaped.

14. An operating method under the environment that the touch screen is simultaneously operated by fingers and the touch object, characterized in that the fingers and the particular touch object operate the system simultaneously, and the touch points corresponding to the fingers are used for determining the touch object-corresponding function or effect.
