Abstract

An input method and a controller of a touch keyboard are provided. The input method includes: detecting a touch behavior performed on the touch keyboard, and identifying the touch behavior to determine whether to output mouse event data, keyboard event data or a combination of mouse event data and keyboard event data.

First claim

What is claimed is:

1. An input method for a touch keyboard, comprising:
configuring a detection circuit to detect a touch behavior of one or more touch objects performed on the touch keyboard;
configuring a control circuit to identify the touch behavior and determine whether the touch behavior corresponds to an action that is simultaneously implemented by a keyboard event and a mouse event; and
configuring the control circuit, in response to determining that the touch behavior corresponds to the action implemented by the keyboard event and the mouse event, to output a combination of mouse event data of the mouse event and keyboard event data of the keyboard event,
wherein the mouse event includes one or more of scrolling a mouse wheel, clicking a left mouse button and clicking a right mouse button, the mouse event data includes data of the one or more of scrolling the mouse wheel, clicking the left mouse button and clicking the right mouse button, the keyboard event includes pressing one or more of a plurality of keys of a keyboard, and the keyboard event data includes data of pressing the one or more key of the keyboard.

2. The input method according to claim 1 , wherein the step of identifying the touch behavior includes:
detecting the one or more touch objects that performs the touch behavior, and calculating at least one touch position of the one or more touch objects; and
analyzing, according to the at least one touch position, at least one sensed amount change of the one or more touch objects, so as to identify the touch behavior.

3. The input method according to claim 2 , wherein the at least one sensed amount change is at least one touch position change of the one or more touch objects, or a sensed amount change at a single touch position.

4. The input method according to claim 1 , wherein the step of identifying the touch behavior includes:
detecting a first touch object and a second touch object that perform the touch behavior, and calculating a first touch position of the first touch object and a second touch position of the second touch object;
analyzing a first path of the first touch object and a second path of the second touch object according to the first touch position and the second touch position; and
identifying the touch behavior according to a relative movement relationship between the first path and the second path.

5. The input method according to claim 1 , wherein the step of identifying the touch behavior includes:
detecting a first touch object and a second touch object that perform the touch behavior, and calculating a first touch position of the first touch object and a second touch position of the second touch object; and
in response to the first touch position being the same as the second touch position, analyzing a time interval between the first touch object and the second touch object, and identifying the touch behavior according to the time interval.

6. The input method according to claim 1 , further comprising:
generating, according to the identified touch behavior, the combination of the mouse event data and the keyboard event data, which is then output to an operating system of a computer.

7. A controller of a touch keyboard, comprising:
a detection circuit configured to detect a touch behavior of one or more touch objects performed on the touch keyboard; and
a control circuit configured to identify the touch behavior and determine whether the touch behavior corresponds to an action that is simultaneously implemented by a keyboard event and a mouse event
so as to determine whether to output a combination of mouse event data and keyboard event data,
wherein the mouse event includes one or more of scrolling a mouse wheel, clicking a left mouse button and clicking a right mouse button, the mouse event data includes data of the one or more of scrolling the mouse wheel, clicking the left mouse button and clicking the right mouse button, the keyboard event includes pressing one or more of a plurality of keys of a keyboard, and the keyboard event data includes data of pressing the one or more key of the keyboard.

8. The controller according to claim 7 , wherein the control circuit is configured to detect the one or more touch objects that performs the touch behavior, and calculate at least one touch position of the one or more touch objects; and
wherein the control circuit is further configured to analyze, according to the at least one touch position, at least one sensed amount change of the one or more touch objects, so as to identify the touch behavior.

9. The controller of claim 8 , wherein the at least one sensed amount change is at least one touch position change of the one or more touch objects, or a sensed amount change at a single touch position.

10. The controller according to claim 7 , wherein the control circuit is configured to detect a first touch object and a second touch object that perform the touch behavior, and calculate a first touch position of the first touch object and a second touch position of the second touch object; and
wherein the control circuit is further configured to analyze a first path of the first touch object and a second path of the second touch object according to the first touch position and the second touch position, and to identify the touch behavior according to a relative movement relationship between the first path and the second path.

11. The controller according to claim 7 , wherein the control circuit is configured to detect a first touch object and a second touch object that perform the touch behavior, and calculate a first touch position of the first touch object and a second touch position of the second touch object; and
wherein the control circuit is further configured to analyze, in response to the first touch position being the same as the second touch position, a time interval between the first touch object and the second touch object, and identifying the touch behavior according to the time interval.

12. The controller according to claim 7 , wherein the control circuit is configured to generate, according to the identified touch behavior, the combination of the mouse event data and the keyboard event data, which is then output to an operating system of an electronic computer.
