Fig. 4 is the method flow schematic diagram of determination touch event provided in an embodiment of the present invention, and with reference to Fig. 4, the present invention is real
Apply in example, ITO touch pads determine that the flow of touch event is as follows：
Step 401, the touch operation in response to ITO touch pads, record the touch duration of touch operation.
Step 402, judge touch duration whether in the range of the corresponding duration of click event；If it is, performing step
403；If it has not, performing step 404.
Step 403, determine touch operation correspondence click event.
Step 404, in real time calculating touch operation corresponding current touch point on ITO touch pads are inclined relative to starting point

Step 405, judge to calculate whether obtained offset is more than or equal to default deviation range；If it is, performing
Step 406；If it has not, performing step 407.
Step 406, determine touch operation correspondence slip event.
Step 407, determine touch operation correspondence long-press event.
For step 401, MCU monitors the capacitance variations on ITO touch pads in real time, if detecting a certain coordinate points has electric capacity
During change, there is touch operation in the coordinate points for determining this generation capacitance variations.Before capacitance variations stopping, electric capacity is persistently recorded
The duration of change as touch operation touch duration.
For step 402, the corresponding duration scope of click event is pre-defined, and this step need to contrast previous step inspection
Whether the touch duration of the touch operation measured is in the range of the pre-defined corresponding duration of click event.
For step 403, if touching duration in the range of the corresponding duration of click event, the touch operation pair can determine that
Answer click event.Determine after click event, MCU can be closed according to the touch event type being pre-configured with is corresponding with control model
In system, inquire about the corresponding control of the click event and be intended to and the working condition of sound equipment is controlled.
For example, in MCU, the broadcasting/pause for the currently playing song of click event correspondence being pre-configured with, then MCU can root
It is intended to according to the control of user, the current title in pause broadcasting, or plays the current title in pause.
For step 404, touch operation corresponding starting point on ITO touch pads, for for this touch operation first
Detect the point of capacitance variations.Touch operation corresponding current touch point, i.e. current time on ITO touch pads, ITO touch pads
The upper coordinate points for producing capacitance variations.
If touching duration exceeds the corresponding duration scope of click event, sustainable record touches duration, and according to generation
The changes in coordinates situation of the point of capacitance variations calculates offset of the current touch point relative to starting point.
For step 405, deviation range is pre-defined.In this step, current touch point is got relative to starting
, it is necessary to judge whether current offset reaches pre-defined deviation range after the offset of point.
For step 406, if current offset has reached pre-defined deviation range, the touch operation can determine that
One slip event of correspondence.MCU is persistently monitored to the changes in coordinates that capacitance variations point is produced on ITO touch pads, and is counted in real time
Calculate offset of the current touch point relative to starting point., will if offset has the change of reduction during continuing to increase
The point for producing reduction change is designated as flex point.Similarly, if offset has increased change during lasting reduction, it will produce
The point of increase change is designated as flex point.When MCU no longer detects the point for there are capacitance variations on ITO touch pads, then last is marked
The point for producing capacitance variations is terminating point of the touch operation on ITO touch pads.
Alternatively, it is determined that during touch operation correspondence slip event, MCU can be according to the slide detected
Starting point and ending point, determine the corresponding glide direction of slip event and/or sliding distance.
In an application scenarios, touch operation does not have direction change on ITO touch pads, i.e., when not detecting flex point,
MCU can corresponding terminating point, relative to the direction of starting point, determines pair of slip event on ITO touch pads according to touch operation
The glide direction answered.In addition, the offset that MCU can also be according to the terminating point detected relative to starting point, it is determined that sliding

Position in the second side close to touch sound equipment button, then can determine that the corresponding glide direction of the slip event is：From
The direction of second side is pointed in one side, determines that the corresponding sliding distance of the slip event is：Between terminating point and starting point
Coordinate offset amount.
In another application scenarios, touch operation has direction change on ITO touch pads, it means that touch operation exists
There is flex point in corresponding sliding process on ITO touch pads.Based on this, starting points of the MCU according to the slide detected, end
Stop and flex point, determine the corresponding glide direction of slip event and/or sliding distance.
For example, MCU cocoas obtain flex point of the touch operation on ITO touch pads in corresponding sliding process.Turned in acquisition
Point after, according to touch operation on ITO touch pads corresponding terminating point, starting point and flex point, determine the cunning of slip event
Dynamic direction.In addition, MCU can also be according to adjacent 2 points between starting point, terminating point and flex point of offset, it is determined that sliding
The sliding distance of event.
Optionally, in a slip event, flex point can have multiple, accordingly, and glide direction can also have multiple.It is theoretical
On, if a slip event has N number of flex point, N is positive integer, then slip event can include N+1 glide direction.
Following part will illustrate how to terminate according to touch operation is corresponding on ITO touch pads with reference to specific example
Point, starting point and flex point, determine the glide direction of slip event.For example, in a slip event, its sliding path is, from
Starting point slides the first offset to flex point, and the second offset is slided to terminating point from flex point.Then, the slip event includes starting
Point points to the first glide direction of flex point, and flex point points to the second glide direction of terminating point.For another example in a slip event
In, its sliding path is, the first offset to the first flex point is slided from starting point, and the second offset is slided to the from the first flex point
Two flex points, the 3rd offset is slided to terminating point from Second Inflexion Point.Then, the slip event points to the first flex point comprising starting point
First glide direction, the first flex point point to the second glide direction of Second Inflexion Point and the 3rd of Second Inflexion Point sensing terminating point is slided
Dynamic direction.
Optionally, when detecting flex point, the sliding distance of slip event is：Slide and start into terminal procedure, starting
The superposition of adjacent 2 offsets between point, at least one flex point and terminating point；Wherein, if cunning indicated by two consecutive points
Dynamic direction is consistent with the positive direction of definition, then the offset between the two consecutive points when being superimposed on the occasion of.If two adjacent
Indicated glide direction is put with the positive direction of definition on the contrary, then the offset between the two consecutive points is negative when being superimposed
Value.
Determine after slip event, MCU can be according to the touch event type and the corresponding relation of control model being pre-configured with
In, the corresponding control of inquiry slip event is intended to and the working condition of sound equipment is controlled.
It is assumed that in the touch event type and the corresponding relation of control model that are pre-configured with MCU：With ITO touch pads

If the corresponding general direction of slip event is parallel with the direction that four side is pointed in the 3rd side, user can determine that
Control be intended to the switching of up/down song.MCU can determine whether that four side side is pointed in specific direction for the 3rd side
To, or four side point to the 3rd side directions and according to the control of user be intended to, by currently playing song switch to it is upper one song
Mesh or next song.
If the corresponding general direction of slip event is parallel with the direction that second side is pointed in first side, user can determine that
Control be intended to control sound equipment broadcast sound volume increase/reduction.Now, MCU need in real time according to current touch point relative to rise
The direction of initial point and offset are controlled to the broadcast sound volume of sound equipment.
If for example, the corresponding direction of slip event is the direction that second side is pointed in first side, can determine that user's
Control is intended to increase volume.MCU can be according to indicated by current touch point relative to the offset of starting point volume increase width
Degree, increases the broadcast sound volume of sound equipment, and controls the broadcast sound volume of sound equipment with the offset produced by the movement of current touch point
Change and adaptations, to produce the effect that volume realizes gradual change with the change of sliding distance.
Similarly, if the corresponding direction of slip event is the direction that first side is pointed in second side, it can determine that user's
Control is intended to reduce volume.MCU can be according to indicated by current touch point relative to the offset of starting point volume down it is small size
Degree, reduces the broadcast sound volume of sound equipment, and controls the broadcast sound volume of sound equipment with the offset produced by the movement of current touch point
Change and adaptations, to produce the effect that volume realizes gradual change with the change of sliding distance.
Optionally, the effect that volume realizes gradual change with the change of sliding distance is produced, can refer to along first side
During being slided to the direction of second side, with current touch point lasting increasing relative to the increase of the offset of starting point
Big volume；When detecting flex point, the direction for pointing to first side along second side is slided, as current touch point is relative to turning
Point offset increase and be gradually reduced volume.Can constantly it be slided in the direction that first side is pointed to along second side
During, as current touch point persistently reduces volume relative to the increase of the offset of starting point；When detecting flex point,
Along first side point to second side direction slide, with current touch point relative to the offset of flex point increase and gradually
Increase volume.In above process, if detecting flex point again, according to the flex point direction adaptability relative with previous flex point
Sound equipment size is adjusted, repeated no more.
It should be appreciated that after the process of gradual change, being opened in above-mentioned volume with the change of sliding distance with regard to volume from slip
The moment begin to for sliding finish time corresponding overall variation, its overall loudness difference sliding distance corresponding with slip event
Indicated volume increases/and reduction amplitude matches, repeats no more.
