Capacitive touch control technologies may sense whether there is a user's finger or other conductive object by a detection capacitor, and a corresponding function can be implemented simply by a light touch with a finger. Currently, touch screens have been widely applied to electronic devices, to implement touch control operations.
In the process of conceiving the present disclosure, the inventor finds that there are at least the following problems in the existing technologies:
(1) Existing electronic devices support only one-dimensional input, but cannot support multi-dimensional input, and pressure detection is not sufficiently accurate.
(2) A simple finger touch control function is only applicable to a limited number of application scenarios. This does not adapt to the development trend of technologies of integrating multiple application functions in one electronic device.
