Wherein, each key of multiple keys includes: sealer, capacitance touch inductive layer, shielded layer, key
Bracket, wherein capacitance touch inductive layer, in the touch action on keyboard, touch action is converted into accordingly for induction effect
Electric signal, each key can independently detect the touch-control situation in the region.
Processing unit, processing unit are configured as: judging whether the capacitance touch inductive layer of key detects that first is predetermined
Touch action, if detecting, the first predetermined touch is acted, and judges whether capacitance touch inductive layer detects the second predetermined touch
Movement, if detecting, the second predetermined touch is acted, and control keyboard is the first cursor output mode, if not detecting, second is pre-
Determine touch action, then control keyboard is the second cursor output mode.Wherein, the first predetermined touch movement is equivalent to switch, is used for
Keyboard is switched to cursor output mode from common input pattern, if not detecting that the first predetermined touch acts, is controlled
The keyboard is normal input pattern.After entering cursor output mode, further detect whether that the second predetermined touch acts,
The movement of second predetermined touch is the first cursor output mode or the second cursor output mould for specifically controlling cursor output mode
Formula.
In one example, the finger of the first predetermined touch movement predetermined quantity is touched toward predetermined direction simultaneously on key
It touches, it is preferred that can be four fingers while touching down, naturally it is also possible to be three fingers while up touch, the disclosure
