Y-axis is positive.
Then, each actual induction point is divided into left side induction point set and right side incudes point set.
Wherein, each induction point in the left side induction point set is all satisfied:It is described
Each induction point in right side induction point set is all satisfied:P is each actual induction point
Serial number, 1≤p≤PN, PN are the sum of actual induction point, PointXpFor the abscissa of p-th of actual induction point, ln is described
Left side incudes the serial number of each induction point in point set, and 1≤ln≤LN, LN are the induction point in left side induction point set
Sum, LPointXlnThe abscissa of the ln induction point in point set is incuded for the left side, rn is the right side induction point
The serial number of each induction point in set, 1≤rn≤RN, RN are that the induction point that the right side incudes in point set is total,

It is arranged according to actual conditions, for example, 5,10,20 or other values can be set to.It should be noted that T value is bigger,
Then calculation amount is also bigger, but computational accuracy is higher；T value is smaller, then calculation amount is also bigger, but computational accuracy is lower, needs root
The two is weighed according to actual conditions.
Then, the separate equations symbol in the preferred symbol packet is counted respectively in each sub-period by the current use
The number that family uses, and the usage frequency of the separate equations symbol in the preferred symbol packet is calculated separately according to the following formula:
Wherein, n is the serial number of formal notation, and 1≤n≤N, N are the sum of the formal notation in the preferred symbol packet, t
For the serial number that sub-period is arranged according to chronological order, 1≤t≤T, the value of more early its t of sub-period on time dimension
It is smaller, UsageNumn,tFor n-th of formal notation in the preferred symbol packet by the active user in t-th of sub-period
The total degree used, WeighttFor preset weight coefficient, and Weightt< Weightt+1, i.e., more rearward the sub- period power
Weight coefficient is bigger, this is because the data closer with current time, reference significance is bigger, and more remote with current time
Data, reference significance is smaller, for example, the data of this week record obviously can more reflect that user is current than data a few months ago
Use habit, SymPrinFor the usage frequency of n-th of formal notation in the preferred symbol packet.
Step S1043, the separate equations symbol in the preferred symbol packet is distributed in virtual formula keyboard head circle
On each virtual key in face.
Wherein, the priority positive of the usage frequency of the separate equations symbol and virtual key corresponding to the separate equations symbol
It closes.The usage frequency of even a certain formal notation is higher, then being disposed at the higher virtual key of priority, (i.e. user uses
Virtual key more smoothly) on, conversely, it is lower to be disposed at priority if the usage frequency of a certain formal notation is lower
Virtual key (i.e. user uses more virtual key not smoothly) on.
Step S105, by the virtual formula keyboard head showing interface on preset human-computer interaction interface.
