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:
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.

2 . The input method according to claim 1 , wherein the step of identifying the touch behavior includes:
detecting at least one touch object that performs the touch behavior, and calculating at least one touch position of the at least one touch object; and analyzing, according to the at least one touch position, at least one sensed amount change of the at least one touch object, 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 at least one touch object, 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 mouse event data, the keyboard event data, or 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 performed on the touch keyboard; and a control circuit configured to identify 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.

8 . The controller according to claim 7 , wherein the control circuit includes:
an object detection module configured to detect at least one touch object that performs the touch behavior, and calculate at least one touch position of the at least one touch object; and a gesture detection module configured to analyze, according to the at least one touch position, at least one sensed amount change of the at least one touch object, 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 at least one touch object, or a sensed amount change at a single touch position.

10 . The controller according to claim 7 , wherein the control circuit includes:
an object detection module 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 a gesture detection module 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 includes:
an object detection module 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 a gesture detection module 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 further includes:
a data generating module configured to generate, according to the identified touch behavior, the mouse event data, the keyboard event data, or the combination of the mouse event data and the keyboard event data, which is then output to an operating system of an electronic computer.
