Abstract

A touch control system includes: a touch panel; an active pen having a plurality of functions, the functions being used for controlling the active pen or the touch panel and initiated only by at least one voice signal, the active pen including: a voice receiving module configured to receive the at least one voice signal; a voice analyzing module configured to analyze the at least one voice signal to generate a controlling command; and a control module configured to determine that the controlling command is configured to control the active pen or the touch panel; and a touch controller electrically connected to the touch panel and receive, in response to the controlling command being configured to control the touch panel, the controlling command.

First claim

What is claimed is:

1. A touch control system, comprising:
a touch panel;
an active pen having a plurality of functions, wherein the functions are used for controlling the active pen or the touch panel and initiated only by at least one voice signal, and the active pen comprises:
a case having a hollow structure;
a voice receiving module disposed in the case and comprising a microphone or a microphone array and configured to receive the at least one voice signal;
a voice analyzing module electrically connected to the microphone or the microphone array and disposed in the case;
a control module electrically connected to the voice analyzing module and disposed in the case; and
a sensing electrode disposed at one end of the active pen; and

a touch controller electrically coupled to the touch panel and configured to receive, in response to the controlling command used for controlling the touch panel, the controlling command;
wherein the active pen is configured to generate a controlling command by analyzing the at least one voice signal through the voice analyzing module and to determine, through the control module, that the controlling command is used for controlling the active pen or the touch panel;
wherein the active pen is configured under control of the control module, in response to the controlling command based on the voice signal for controlling the active pen, to perform a protocol switching function, and the protocol switching function is used for controlling the active pen to switch to a protocol suitable for the touch controller;
wherein the active pen is configured under control of the control module, in response to the controlling command based on the voice signal for controlling the touch panel, to transmit the controlling command to the touch controller via the sensing electrode and the touch panel, and the touch controller is configured to perform an operation of the active pen on the touch panel according to the controlling command.

2. The touch control system according to claim 1 ,
wherein the active pen is configured under control of the control module, in response to the controlling command used for controlling the active pen, to perform a power control function, and the power control function is used for controlling power of the active pen.

3. The touch control system according to claim 1 , wherein the active pen, under control of the control module, uses the protocol between the active pen and the touch controller to transmit the controlling command to the touch controller.

4. A sensing method of a touch control system, the touch control system comprising a touch panel, an active pen, and a touch controller, the active pen comprising a case having a hollow structure, a voice receiving module comprising a microphone or a microphone array, a voice analyzing module electrically to the microphone or the microphone array and disposed in the case, a control module electrically connected to the voice analyzing module and disposed in the case, and a sensing electrode disposed at one end of the active pen, the active pen having a plurality of functions, the functions being used for controlling the active pen or the touch panel and initiated only by at least one voice signal, and the sensing method of the touch control system comprising:
receiving the at least one voice signal by the voice receiving module;
using the active pen to generate a controlling command by analyzing the at least one voice signal through the voice analyzing module;
using the active pen to determine, through the control module, that the controlling command is used for controlling the active pen or the touch panel; and
using the touch controller to receive, in response to the controlling command used for controlling the touch panel, the controlling command;
wherein in response to the controlling command based on the voice signal for controlling the active pen, the active pen, under control of the control module, performs a protocol switching function, and the protocol switching function is used for controlling the active pen to switch to a protocol suitable for the touch controller;
wherein in response to the controlling command based on the voice signal for controlling the touch panel, the active pen, under control of the control module, transmits the controlling command to the touch controller via the sensing electrode and the touch panel, and the touch controller is configured to perform an operation of the active pen on the touch panel according to the controlling command.

5. The sensing method of the touch control system according to claim 4 , wherein in response to the controlling command, the active is configured, under control of the control module, to perform a power control function, and the power control function is used for controlling power of the active pen.

6. The sensing method of the touch control system according to claim 4 , wherein the active pen, under control of the control module, uses the protocol between the active pen and the touch controller to transmit the controlling command to the touch controller.

7. An active pen, having a plurality of functions, wherein the functions are used for controlling the active pen or a touch panel electrically coupled to a touch controller and initiated only by at least one voice signal, and the active pen comprises:
a case having a hollow structure;
a voice receiving module disposed in the case and comprising a microphone or a microphone array and configured to receive the at least one voice signal;
a voice analyzing module electrically connected to the microphone or the microphone array and disposed in the case;
a sensing electrode disposed at one end of the active pen; and
a control module electrically connected to the voice analyzing module and disposed in the case;
wherein the active pen is configured under control of the control module, in response to the controlling command based on the voice signal for controlling the active pen, to perform a protocol switching function, and the protocol switching function is used for controlling the active pen to switch to a protocol suitable for the touch controller; and
wherein the active pen is further configured under control of the control module, in response to the controlling command based on the voice signal for controlling the touch panel, to transmit the controlling command to the touch controller via the sensing electrode and the touch panel, and the touch controller is configured to perform an operation of the active pen on the touch panel according to the controlling command.
