Description
Technical field
The present invention relates to induction of signal treatment technology, and in particular to a kind of touch feedback method and terminal.
Background technology
When being manipulated on mobile terminal such as mobile phone, flat board touch-screen electronic equipment, touch-screen will not picture
Physical button can feed back pressure sensitivity like that, there will not be other any touch feedbacks；For example：When playing mobile phone games
It is always the wide gap that can not be crossed over to lack feel.
Industry is continually striving to strengthen the interaction capabilities of touch apparatus using many modes, for example：Apple Inc. is most
New opplication 3D Touch touch technologies, enable iPhone 6S to distinguish the weight of user's pressing, so-called 3D
Touch touch technologies are the upgradings to existing capacitance touching control screen technology, are increased below existing Touch Screen
Deformation-sensor, measures screen deformation and detects screen because of the deformation that human body temperature changes and produces, to realize
Pressure identification ability.But no matter capacitance touching control screen technology or 3D Touch touch technologies belong to it is unidirectional
Control lacks in operation screen, it is necessary to the result of touch is known in the change of user concern screen display content
While to user physically directly in response to and feedback, this causes many game roles to play the part of and simulated operation
Had a greatly reduced quality Deng the strong game application experience of requirement of real-time.
Therefore, having the technology felt to the actual manipulation of operator at present, the manipulation is felt to include physics
Two kinds of touch feedback and galvanism feedback technique：
For physical tactile feedback technique, the principle of the technology be set below screen can actual motion thing
Body, forms raised, to simulate the tactile of actual button, such as China Patent No. is on screen
200680008130.3 file disclosed in：A touch control terminal is set to be positioned on rear side of display terminal, this is touched
Control terminal can be moved relative to display terminal, and producing deformation in screen side produces tactile.
It is to utilize Capacitance Coupled principle, by electric current to finger sensory nerve and fortune for galvanism technology
It is dynamic to stimulate, cause cell excitement, produce the nervous excitation ripple of impulse form, pass to nervous centralis and simulate
Different sensations.If China Patent No. is disclosed in 201210537346.6 file：It is former using Capacitance Coupled
Reason, is touching one electrode of screen arranged beneath, offscreen surface arrangement insulative dielectric material, because of human body
Belong to conductor, when finger is touched on screen, simulation forms another electrode, the close simulation of this two panels conductor
Go out electric capacity, by controlling the voltage change of screen lower electrode, capacitance coupling effect produced with finger contact position,
Forming induced-current makes finger produce sense of touch mode.
In above two feedback technique, for physical tactile feedback technique, have the disadvantage that：It can produce
The mechanical terminations size of motion is larger, is easily integrated into electronic equipment；Easily loss is not easy-maintaining and more
Change, and energy expenditure is larger；Sense of touch is single.
For galvanism feedback technique, have the disadvantage that：Because of the contact area very little of finger and screen,
The coupled capacitor capacity of generation is very small, low capacity electric capacity have hinder low-frequency current by, be easy to high-frequency electrical
The characteristic that stream passes through, as power frequency increase conduction constantly strengthens, but as frequency elevated currents are to machine
The stimulation of body can weaken rapidly, using Capacitance Coupled method to that can have excited sensation and kinesitherapy nerve to exist
Below 1000Hz low-frequency current conduction is very poor, therefore the low-frequency current size produced is limited, it is difficult to provide
Obvious touch feedback.
