Abstract

Disclosed is a control method and control device for a working mode of a touch screen. The control method comprises: acquiring current touch operation data generated when a user operates a touch screen; performing logic judgment on whether to switch the working mode according to a current working mode of the touch screen and the touch operation data, and if yes, sending a switching signal to a touch screen control chip to enable the touch screen control chip to control and switch the working mode of the touch screen when receiving the switching signal. The operating intent of the user can be automatically identified according to the touch operation data and the current working mode of the touch screen, and the working mode of the touch screen is controlled to be switched to a corresponding mode, thereby the touch operation of the user is facilitated and the user experience optimized.

First claim

What is claimed is:

1. A control method for a working mode of a touch screen, comprising:
acquiring current touch operation data generated when a user operates a touch screen; and
performing logic judgment on whether to switch the working mode according to a current working mode of the touch screen and the touch operation data, and if yes, sending a switching signal to a touch screen controlling chip, to enable the touch screen controlling chip to control and switch the working mode of the touch screen when receiving the switching signal;
wherein the working modes of the touch screen comprise: a hand gesture mode and a simulated mouse mode; and
the step of performing logic judgment on whether to switch the working mode according to a current working mode of the touch screen and the touch operation data comprises:
when the current working mode of the touch screen is the hand gesture mode, and the touch operation data are single-finger slow and continuous moving operation data, determining to switch the working mode, generating a first switching signal for switching the current working mode to the simulated mouse mode, and sending the first switching signal to the touch screen controlling chip;
when the current working mode of the touch screen is the hand gesture mode, and a user interaction tool of a head-mounted device changes from an externally connected physical mouse to the touch screen, and the received touch operation data are single-finger slow and continuous moving operation data, determining to switch the working mode, generating a first switching signal for switching the current working mode to the simulated mouse mode, and sending the first switching signal to the touch screen controlling chip;
when the current working mode of the touch screen is the simulated mouse mode, and the touch operation data are multiple-finger operation data, determining to switch the working mode, generating a second switching signal for switching the current working mode to the hand gesture mode, and sending the second switching signal to the touch screen controlling chip; and
when the current working mode of the touch screen is the simulated mouse mode, and the touch operation data are single-finger quick sliding operation data, determining to switch the working mode, generating a second switching signal for switching the current working mode to the hand gesture mode, and sending the second switching signal to the touch screen controlling chip.

2. The method according to claim 1 , wherein before the step of performing logic judgment on whether to switch the working mode according to a current working mode of the touch screen and the touch operation data, the method further comprises:
setting in advance a configuration option to turn on or turn off the automatic switching of the working mode of the touch screen in a system configuration file; and
reading state information of the configuration option, and performing logic judgment on whether to switch the working mode according to a current working mode of the touch screen and the touch operation data when the configuration option is in a turned-on state.

3. The method according to claim 2 , further comprising:
providing a call interface of a configuration option to turn on or turn off the automatic switching of the working mode of the touch screen to a third party application; and
receiving, by the third party application, operation information for turning on the automatic switching of the working mode of the touch screen or operation information for turning off the automatic switching of the working mode of the touch screen that are inputted by the user.

4. The method according to claim 1 , further comprising:
controlling to present a mouse pointer widget on a user interface according to a result of switching after sending the first switching signal to the touch screen controlling chip.

5. A control device for a working mode of a touch screen, comprising:
a data acquiring module, for acquiring current touch operation data of a user;
a working mode controlling module, for performing logic judgment on whether to switch the working mode according to a current working mode of the touch screen and the touch operation data, and if yes, sending a switching signal to a touch screen controlling chip; and
the touch screen controlling chip, for controlling and switching the working mode of the touch screen when receiving the switching signal;
wherein the working modes of the touch screen comprise: a hand gesture mode and a simulated mouse mode;
the working mode controlling module particularly comprises: a logical judgment module and a signal generating module; and
the logical judgment module is for, when a current working mode of the touch screen is the hand gesture mode, and the touch operation data are single-finger slow and continuous moving operation data, determining to switch the working mode and sending a judgment result to the signal generating module; and the signal generating module is for, according to the judgment result of the logical judgment module, generating a first switching signal for switching the current working mode to the simulated mouse mode, and sending the first switching signal to the touch screen controlling chip;
or, the logical judgment module is for, when a current working mode of the touch screen is the hand gesture mode, and a user interaction tool of a head-mounted device changes from an externally connected physical mouse to the touch screen, and the received touch operation data are single-finger slow and continuous moving operation data, determining to switch the working mode and sending a judgment result to the signal generating module; and the signal generating module is for, according to the judgment result of the logical judgment module, generating a first switching signal for switching the current working mode to the simulated mouse mode, and sending the first switching signal to the touch screen controlling chip;
or, the logical judgment module is for, when a current working mode of the touch screen is the simulated mouse mode, and the touch operation data are multiple-finger operation data, determining to switch the working mode and sending a judgment result to the signal generating module; and the signal generating module is for, according to the judgment result of the logical judgment module, generating a second switching signal for switching the current working mode to the hand gesture mode, and sending the second switching signal to the touch screen controlling chip;
or, the logical judgment module is for, when a current working mode of the touch screen is the simulated mouse mode, and the touch operation data are single-finger quick sliding operation data, determining to switch the working mode and sending a judgment result to the signal generating module; and the signal generating module is for, according to the judgment result of the logical judgment module, generating a second switching signal for switching the current working mode to the hand gesture mode, and sending the second switching signal to the touch screen controlling chip.

6. The device according to claim 5 , further comprising: a configuration option setting module, for setting in advance a configuration option to turn on or turn off the automatic switching of the working mode of the touch screen in a system configuration file; and
the working mode controlling module is particularly for reading state information of the configuration option, and performing logic judgment on whether to switch the working mode according to a current working mode of the touch screen and the touch operation data when the configuration option is in a turned-on state.

7. The device according to claim 6 , further comprising:
